Abstract
Objective: To compare the postoperative liver function injury condition in patients with intermediate-and advanced-stage hepatocellular carcinoma (HCC) treated with hepatic artery infusion chemotherapy (HAIC) and hepatic artery chemoembolization (TACE) combined with immune checkpoint inhibitors (ICIs) and multi-target tyrosine kinase inhibitors (TKIs). Methods: Patients with intermediate-and advanced-stage HCC who were admitted and treated with HAIC/TACE+ICIs+TKIs therapy at Nanfang Hospital of Southern Medical University from January 2019 to November 2021, with follow-up up to July 2023, were retrospectively enrolled. The results of liver function tests within one week before interventional surgery and on the first day after surgery were recorded. The degree of postoperative liver injury was graded according to the common terminology criteria for adverse events 5.0 (CTCAE 5.0). The treatment efficacy was evaluated according to RECIST 1.1 criteria. Measurement data were compared between groups using a t-test or a non-parametric rank sum test. Enumeration data were compared between the groups using the χ(2) test or Fisher's exact probability method. The survival condition differences were analyzed by the log-rank method. Results: This study included 82 and 77 cases in the HAIC and TACE groups. There were no statistically significant differences between the two groups of patients in terms of gender, age, physical condition score, number of tumors, presence or absence of liver cirrhosis, Child-Pugh grade, albumin-bilirubin (ALBI) grade, and combined ICIs and TKIs . The HAIC group had later tumor staging, a greater tumor burden, poorer liver reserve function, and a larger proportion of patients in stage C (81.7% vs. 63.6%), χ(2)=6.573, P = 0.01). There were 53 cases (64.6% vs. 32.5%) with a maximum tumor diameter of ≥ 10cm, χ(2)=16.441, P < 0.001), and more patients had a retention rate of ≥ 10% for indocyanine green (ICG) at 15 minutes (68.3% vs. 51.9%, P = 0.035). The postoperative incidence rate of increased levels of alanine aminotransferase, aspartate aminotransferase, and total bilirubin was significantly lower in the HAIC group than that in the TACE group (28.0% vs. 63.6%, χ(2)=20.298, P < 0.001, 54.9% vs. 85.7%, χ(2)=17.917, P < 0.001;40.2% vs. 55.8%, χ(2)=3.873, P = 0.049). The number of patients with postoperative ALBI grade 3 was significantly lower in the HAIC group than that in the TACE group (6.1% vs. 16.9%, χ(2)=4.601, P = 0.032). There was no statistically significant difference in the incidence rate of postoperative hypoalbuminemia, activated partial thromboplastin time, or increased international standardized ratio between the two groups of patients. There was no statistically significant difference in median progression-free survival (7.3 months vs. 8.2 months, P = 0.296) or median overall survival (16.5 months vs. 21.9 months, P = 0.678) between the two groups of patients. Conclusion: The incidence rate of postoperative liver injury is higher in patients with intermediate-and advanced-stage HCC treated with TACE combined with ICIs and TKIs than in patients with HAIC combined with ICIs and TKIs.

Abstract
Objective: To compare the effects of the China Children's Asthma Action Plan (CCAAP)-based remote joint management model with traditional management model on the control of childhood asthma. Methods: A retrospective cohort study was conducted to analyze the general data and asthma control assessment data of 219 children with asthma who attended the respiratory department of Guangzhou Women's and Children's Medical Center from April 2021 to October 2021 and were followed up for 1 year or more. According to the follow-up management model, the CCAAP-based remote joint management model was used in the observation group and the traditional management model was used in the control group, and the propensity score matching method was applied to match the data of children in the two management models for comparison. Paired-samples t-test, Wilcoxon signed-rank test, McNemar χ2-test or χ2-test or nonparametric tests were used to compare the general data and asthma control assessment data between the two matched groups of children. Results: Among 219 children with asthma, 145 were male and 74 were female, aged at consultation (7.2±2.4) years. There were 147 cases in the observation group and 72 cases in the control group, and 27 cases in each of the observation and control groups were successfully matched. The number of asthma exacerbation aura, acute exacerbations, and emergency room visits or hospitalizations for asthma exacerbations were lower in the observation group than in the control group after pairing (1 (0, 2) vs. 3 (1, 5) times, 0 (0,0) vs. 0 (0, 1) times, 0 (0,0) vs. 1 (0, 1) times, Z=-3.42, -2.58, -3.17, all P<0.05). The use of peak flowmeters was higher in children aged 5 years and older in the observation group than in the control group after pairing (100% (22/22) vs. 13% (3/23), χ2=54.00,P<0.001). The ratio of actual to predicted 1st second expiratory volume of force after follow-up in the observation group after pairing was higher than that before follow-up in the observation group and after follow-up in the control group ((95±11)% vs. (85±10)%, (95±11)% vs. (88±11)%, t=-3.40, 2.25, all P<0.05). The rate of complete asthma control after follow-up was higher in both the observation and control groups after pairing than before follow-up for 12 months in both groups (93% (25/27) vs. 41% (11/27), 52% (14/27) vs. 41% (11/27), H=56.19, 45.37, both P<0.001), and the rate of complete control of asthma in children in the observation group was higher than that in the control group at 3 and 12 months of follow-up management (56% (15/27) vs. 25% (5/20), 93% (25/27) vs. 52% (14/27), χ2=47.00, 54.00, both P<0.001). The number of offline follow-up visits, inhaled hormone medication adherence scores, and caregiver's asthma perception questionnaire scores were higher in the observation group than in the control group after pairing (6 (4, 8) vs. 4 (2,5), (4.8±0.3) vs. (4.0±0.6) score, (19.3±2.6) vs. (15.2±2.7) score, Z=6.58, t=6.57, 5.61, all P<0.05), and the children in the observation group had lower school absences, caregiver absences, asthma attack visit costs, and caregiver PTSD scores than the control group (0 (0,0) vs.3 (0, 15) d, 0 (0,0) vs. 3 (0, 10) d, 1 100 (0, 3 700) vs. 5 000 (1 000, 10 000) yuan, 1.3 (1.1, 1.9) vs. 2.0 (1.2, 2.7) score, Z=-2.89, -2.30, 2.74, 2.73, all P<0.05). Conclusion: The CCAAP-based joint management model of asthma control is superior to the traditional management model in the following aspects: it can effectively improve asthma control, self-monitoring, and lung function in children; it can improve treatment adherence and caregivers' asthma awareness; and it can reduce the duration of absenteeism from school, the cost of asthma exacerbation visits, and caregiver's negative psychology.

Abstract
Objective: To investigate the value of histogram parameters in quantifying brain development trajectory at slice of anterior and posterior horns of lateral ventricles on conventional brain MRI in normal children aged 0-5 years. Methods: Routine brain MRI data [apparent diffusion coefficient (ADC) map, T1-weighted imaging (T1WI), and T2-weighted imaging (T2WI)] were retrospectively collected from 300 children aged 0-5 years who underwent MRI at Children 's Hospital of Nanjing Medical University from April 2014 to November 2021, 154 males and 146 females, aged [M (Q1, Q3) ] 35.57(17.98,50.66)months. According to the random sampling method, they were divided into training set (n=240) and validation set (n=60) in a ratio of 8∶2. The training set was divided into 6 groups according to age:≤0.5 years, 24 persons; >0.5-≤1 years,21 persons; >1-≤2 years,31 persons; >2-≤3 years,44 persons; >3-≤4 years,42 persons; >4-≤5 years,78 persons. MRIcron software was used to delineate the whole brain at the level of the anterior and posterior horns of the lateral ventricles of the three MRI data as the region of interest. Then gray histograms and their parameters [including mean, maximum, minimum, skewness, kurtosis, mode, variance, and percentiles at 5% intervals from 10% to 95%(10th-95th) ]were obtained. Intra-class correlation coefficients (ICC) were used to assess consistency of intra-observer and inter-observer measurement. Representative parameters were selected by Spearman correlation analysis and curve fitting. The linear regression coefficient β represented development rates at different ages. The selected curve regression models were applied to the validation set, and the reliability of the model was evaluated with accuracy. Results: Intra-observer and inter-observer histogram measurement parameters were generally in good consistency (ICC>0.800, all P<0.001). Histogram parameters ADC 10th-65th, T1WI 55th-80th and T2WI 10th-45th were highly correlated with age (∣r∣≥0.700, 0.600 and 0.600 respectively; all P<0.001). ADC 30th and T2WI 10th had the greatest goodness of fit (R²=0.871, 0.873; both P<0.001). Map of brain development trends showed that ADC 30th and T2WI 10th decreased with age. ADC 30th changed rapidly before the age of 2 years, most significantly within 6 months, and the rate of decrease slowed down after 2 years old. T2WI 10th decreased rapidly within 1 year, and moderately after 1 year old. The curve regression models of ADC 30th and T2WI 10th had higher accuracy in validation set [93% (56/60) and 95% (57/60), respectively]. Conclusion: Histogram parameters can quantify brain developmental trajectories at slice of anterior and posterior horns of lateral ventricles on conventional MRI in normal children aged 0-5 years, and obtain the brain development curves reflecting this slice of this age group.

Abstract
Objective: To explore the effects and mechanism of water-soluble chitosan hydrogel on infected full-thickness skin defect wounds in diabetic mice. Methods: The experimental research method was adopted. The control hydrogel composed of polyvinyl alcohol and gelatin, and the water-soluble chitosan hydrogel composed of the aforementioned two materials and water-soluble chitosan were prepared by the cyclic freeze-thaw method. The fluidity of the two dressings in test tube before and after the first freeze-thawing was generally observed, and the difference in appearance of the final state of two dressings in 12-well plates were compared. According to random number table (the same grouping method below), the cell strains of L929 and HaCaT were both divided into water-soluble chitosan hydrogel group and control hydrogel group, respectively. After adding corresponding dressings and culturing for 24 h, the cell proliferation activity was measured using cell counting kit 8. Rabbit blood erythrocyte suspensions were divided into normal saline group, polyethylene glycol octyl phenyl ether (Triton X-100) group, water-soluble chitosan hydrogel group, and control hydrogel group, which were treated accordingly and incubated for 1 hour, and then the hemolysis degree of erythrocyte was detected by a microplate reader. Twenty-four female db/db mice aged 11-14 weeks were selected, and full-thickness skin defect wounds on their backs were inflicted and inoculated with the methicillin-resistant Staphylococcus aureus (MRSA), 72 h later, the mice were divided into blank control group, sulfadiazine silver hydrogel group, control hydrogel group, and water-soluble chitosan hydrogel group, which were treated accordingly. On post injury day (PID) 0 (immediately), 7, 14, and 21, the healing of the wound was observed. On PID 14 and 21, the wound healing rate was calculated. On PID 14, MRSA concentration in wounds was determined. On PID 21, the wounds were histologically analyzed by hematoxylin and eosin staining; the expression of CD31 in the wounds was detected by immunofluorescence method, and its positive percentage was calculated. Raw264.7 cells were taken and divided into interleukin-4 (IL-4) group, blank control group, control hydrogel group, and water-soluble chitosan hydrogel group, which were treated accordingly. At 48 h of culture, the percentages of CD206 positive cells were detected by flow cytometry. The number of samples was all 3. Data were statistically analyzed with independent sample t test, one-way analysis of variance, analysis of variance for repeated measurement, least significant difference test, and Dunnett T3 test. Results: Two dressings in test tube had certain fluidity before freeze-thawing and formed semi-solid gels after freeze-thawing for once. The final forms of two dressings in 12-well plates were basically stable and translucent sheets, with little difference in transparency. At 24 h of culture, the cell proliferation activities of L929 and HaCaT in water-soluble chitosan hydrogel group were significantly higher than those in control hydrogel group (with t values of 6.37 and 7.50, respectively, P<0.01). At 1 h of incubation, the hemolysis degree of erythrocyte in water-soluble chitosan hydrogel group was significantly lower than that in Triton X-100 group (P<0.01), but similar to that in normal saline group and control hydrogel group (P>0.05). On PID 0, the traumatic conditions of mice in the 4 groups were similar. On PID 7, more yellowish exudates were observed inside the wound in blank control group and control hydrogel group, while a small amount of exudates were observed in the wound in sulfadiazine silver hydrogel group and water-soluble chitosan hydrogel group. On PID 14, the wounds in blank control group and control hydrogel group were dry and crusted without obvious epithelial coverage; in sulfadiazine silver hydrogel group, the scabs fell off and purulent exudate was visible on the wound; in water-soluble chitosan hydrogel group, the base of wound was light red and obvious epithelial coverage could be observed on the wound. On PID 14, the wound healing rate in water-soluble chitosan hydrogel group was significantly higher than that in the other 3 groups (all P<0.01). On PID 21, the wound in water-soluble chitosan hydrogel group was completely closed, while the wounds in the other 3 groups were not completely healed; the wound healing rate in water-soluble chitosan hydrogel group was significantly higher than that in the other 3 groups (all P<0.01). On PID 14, the concentration of MRSA in the wound in water-soluble chitosan hydrogel group was significantly lower than that in blank control group (P<0.01), but similar to that in control hydrogel group and sulfadiazine silver hydrogel group (P>0.05). On PID 21, the new epidermis was severely damaged in blank control group; the epidermis on the wound in control hydrogel group also had a large area of defect; complete new epidermis had not yet being formed on the wound in sulfadiazine silver hydrogel group; the wound in water-soluble chitosan hydrogel group was not only completely covered by the new epidermis, the basal cells of the new epidermis were also regularly aligned. On PID 21, the percentage of CD31 positivity in the wound in water-soluble chitosan hydrogel group was (2.19±0.35)%, which was significantly higher than (0.18±0.05)% in blank control group, (0.23±0.06)% in control hydrogel group, and (0.62±0.25)% in sulfadiazine silver hydrogel group, all P<0.01. At 48 h of culture, the percentage of CD206 positive Raw264.7 cells in water-soluble chitosan hydrogel group was lower than that in IL-4 group (P>0.01) but significantly higher than that in blank control group and control hydrogel group (P<0.05 or P<0.01). Conclusions: The water-soluble chitosan hydrogel has good biosafety and can induce higher level of macrophage M2 polarization than control hydrogel without water-soluble chitosan, so it can enhance the repair effect of MRSA-infected full-thickness skin defect wounds in diabetic mice and promote rapid wound healing.

Abstract
Objectives There has been slow adoption of thyroid ultrasound guidelines with adherence rates as low as 30% and no population-based studies investigating adherence to guideline-based malignancy risk assessment. We therefore evaluated the impact of adherence to the 2015 ATA guidelines or 2017 ACR-TIRADS guidelines on the quality of thyroid ultrasound reports in our healthcare region. Methods We reviewed 899 thyroid ultrasound reports of patients who received fine-needle aspiration biopsy and were diagnosed with Bethesda III or IV nodules or thyroid cancer. Ultrasounds were reported by radiology group 1, group 2, or other groups, and were divided into pre-2018 (before guideline adherence) or 2018 onwards. Reports were given a utility score (0-6) based on how many relevant nodule characteristics were included. Results Group 1 had a pre-2018 utility score of 3.62 and 39.4% classification reporting rate, improving to 5.77 and 97.0% among 2018-onwards reports. Group 2 had a pre-2018 score of 2.8 and reporting rate of 11.5%, improving to 5.58 and 93.3%. Other radiology groups had a pre-2018 score of 2.49 and reporting rate of 32.2%, improving to 3.28 and 61.8%. Groups 1 and 2 had significantly higher utility scores and reporting rates in their 2018-onward reports when compared to other groups' 2018-onward reports, pre-2018 group 1 reports, and pre-2018 group 2 reports. Conclusions Dedicated adherence to published thyroid ultrasound reporting guidelines can lead to improvements in report quality. This will reduce diagnostic ambiguity and improve clinician's decision-making, leading to overall reductions in unnecessary FNA biopsy and diagnostic surgery.

Abstract
Objective: To explore the effect of atlantoaxial fusion on the growth and development of children's cervical spine. Methods: The clinical data of 12 children with atlantoaxial dislocation who underwent posterior atlantoaxial fusion at Department of Orthopaedics,the 909th Hospital of Joint Logistics Support Force of Chinese People's Liberation Army from June 2002 to September 2013 were retrospective analyzed. There were 7 males and 5 females,with age of (8.1±3.1)years (range:3 to 13 years).Nine cases were traumatic and 3 cases were congenital malformations,1 of the children had Down syndrome. All children underwent posterior atlantoaxial fusion. Furthermore,the information of the height and anteroposterior width of the cervical vertebral bodies and vertical growth rate of the fusion mass were collected from all patients immediately postoperatively and during the follow-up.The range of motion in cervical spine were collected preoperatively and during follow-up period. Data were compared using independent sample t test, paired sample t test and repeated-measurement. Results: All 12 children had regular follow-up within (122.4±25.3)months(range:65 to 163 months). The height and anteroposterior width of the cervical vertebral bodies were similar to these results with those in published reports of growth in normal children of the same age(all P<0.01). At the last follow-up,atlantoaxial fusion of 11 cases had substantial growth (vertical growth rate of the fusion mass:11 cases ≥10%, 1 case <10%);the range of motion in cervical spine was close to the normal level (flexion(55.2±5.0)°,extension (65.3±4.9)°,left bending (41.7±4.5)°,right bending (42.4±4.4)°,left rotation (66.4±5.6)°,right rotation (68.5±5.8)°). Conclusions: Atlantoaxial fusion surgery is satisfactory in the treatment of pediatric atlantoaxial dislocation.During the follow-up,the growth and development of the cervical spine is close to that of normal children of the same age.In long-term observation,it has been found that the operation has no negative effect on the growth and development of the children's cervical spine.

Abstract
Rectal cancer is a common malignant tumor of the digestive tract, and surgery is the main treatment strategy. Disorders of bowel, anorectal and urogenital function remain common problems after total mesorectal resection (TME), which seriously decreases the quality of life of patients. Surgical nerve damage is one of the main causes of the complications, while TME with pelvic autonomic nerve preservation is an effective way to reduce the occurrence of adverse outcomes. Intraoperative nerve monitoring (IONM) is a promising method to assist the surgeon to identify and protect the pelvic autonomic nerves. Nevertheless, the monitoring methods and technical standards vary, and the clinical use of IONM is still limited. This review aims to summarize the researches on IONM in rectal and pelvic surgery. The electrical nerve stimulation technique and different methods of IONM in rectal cancer surgery are introduced. Also, the authors discuss the limitations of current researches, including methodological disunity and lack of equipment, then prospect the future direction in this field.

Abstract
Objective: To investigate the clinical effects of negative pressure wound therapy (NPWT) in treating the poor healing of incisions after different abdominal operations. Methods: The retrospective observational study was conducted. From June 2019 to December 2020, 42 patients with poor healing of incisions after abdominal surgery were admitted to Center of Burns and Trauma of the First Affiliated Hospital of Naval Medical University, including 29 males and 13 females, aged 23-81 years. The disease course of poor healing of abdominal incision was 3-60 d. The preoperative examination of patients was completed after admission, and NPWT was used after debridement. According to the dehiscence level of incision, the negative pressure value of -10.64 to -6.65 kPa was set. The incisions were sutured in the second stage when the incisions had good blood circulation. The cause of abdominal surgery, the dehiscence level and the cause of poor healing of abdominal incision were investigated, and the final healing of abdominal incision and the occurrence of complication were observed. Results: The causes of abdominal operations in this group of patients who ocurred poor healing of abdominal incisions were ranked according to the composition ratio, with the top 4 causes being colon cancer (9 cases, accounting for 21.4%), bile duct disease (8 cases, accounting for 19.0%), liver cancer (5 cases, accounting for 11.9%), and appendicitis (4 cases, accounting for 9.5%). There were 25 cases (59.5%) with dehiscence of abdominal incision in the deep fascia layer, and the other 17 cases (40.5%) with dehiscence of abdominal incision in the superficial fascia layer. The causes of poor healing of abdominal incision were ranked according to the composition ratio, with the top 3 causes being infection (24 cases, accounting for 57.1%), fat liquefaction (11 cases, accounting for 26.2%), and suture reaction (5 cases, accounting for 11.9%). The blood circulation in 40 patients was improved after being treated with NPWT, and the incisions were sutured in the second stage. The incisions healed well when the suture lines were removed in the second to third week. Intestinal fistula and bile leakage developed during the NPWT treatment, respectively in the other 2 patients, in which negative pressure equipment was removed subsequently, and the incisions healed after adequate drainage and conventional dressing changes. Conclusions: NPWT is effective in treating poor healing of abdominal incision after different abdominal surgeries. The clinicians need to comprehensively assess the patient's condition to determine when and how to use NPWT to avoid the occurrence of intestinal fistula, bile leakage, and other complications.

Abstract
Objective: To investigate the present situation of unintended pregnancy within two years postpartum and its influencing factors in China. Methods: Participants who delivered a live birth at 60 hospitals in 15 provinces in the eastern, central and western regions of China during July 2015 to June 2016 were interviewed by using structured questionnaire. Information on occurrence of unintended pregnancy within 2 years after delivery, postpartum contraceptive use, sexual resumption, breastfeeding, and women's socio-demographic characteristics, and so on, were collected. Life-table analysis, cluster log-rank tests and a 2-level Cox regression model were used for data analysis. Results: A total of 18 045 postpartum women were investigated. The cumulative 1- and 2-year unintended pregnancy rates after delivery were 5.3% (95%CI: 4.5%-6.1%) and 13.1% (95%CI: 11.3%-14.8%), respectively. Cox regression model analysis showed that the risk of unintended pregnancy within 2 years postpartum were increased in younger women, ethnic minorities, women with abortion history, and those who had a vaginal delivery with short lactation time and late postpartum contraceptive initiation (all P<0.01). The risk of postpartum unintended pregnancy was not associated with geographic regions and hospitals where women gave a birth (all P>0.05). Conclusions: In China, the risk of unintended pregnancy within 2 years after delivery is relatively high. Service institutions and service providers should improve the quality of postpartum family planning services, promote the use of high effect contraceptive methods, and educate women to use a method at the time of their sexual resumption or even before.

Abstract
Objective: To analyze the characteristics of magnetic resonance imaging (MRI) and clinical etiology of ovarian infertility. Methods: The data of infertile women who underwent 3.0T MRI and magnetic resonance hysterosalpingography (MR-HSG) examination in the Affiliated Hospital of Nanjing University of Chinese Medicine from September 2017 to March 2020 were collected. The ovarian factors of infertility, as well as the abnormalities of bilateral fallopian tubes and uterus, were evaluated. Etiologies assessed by MRI were finally confirmed by hysteroscopy, laparoscopy, surgery, or a comprehensive clinical diagnosis. Results: Among 1 351 patients, 1 296 cases were eligible and included for further analysis. Evaluated by MRI and MR-HSG, 494(38.12%) cases had ovarian abnormalities, including 239(48.38%) cases of ovarian endometriosiss, 116(23.48%) cases of polycystic ovary syndrome (PCOS), 37(7.49%) cases of diminished ovarian reserve (DOR), 33(6.68%) cases of ovarian mass, 28(5.67%) cases of ovarian injury, and 41(8.30%) cases who had at least two kinds of ovarian diseases. Unilateral and bilateral ovarian abnormalities accounted for 52.02% (257/494) and 47.98%(237/494), respectively.In total, 453 of 494(91.7%) patients had only one kind of ovarian disease. Among the 494 patients, 103(20.85%) cases had abnormal ovary with normal uterus and fallopian tubes, and the other 391(79.15%) cases had abnormalities not only in ovary, but in fallopian tube and/or uterus. Conclusion: Infertility-related ovarian diseases have certain characteristics of MRI findings. 3.0T MRI is useful for comprehensive analysis of etiology in ovarian infertility. Combined with MR-HSG, it provides one-stop assessments of the pelvic factors in female infertility.

Abstract
Objective: To analyze the clinical efficacy and safety of camrelizumab combined with apatinib as a second-line therapy for unresectable hepatocellular carcinoma (HCC). Methods: Ninety-four cases with mid-and advanced-stage HCC who received camrelizumab combined with apatinib as second-line treatment were enrolled. Routine blood test, blood biochemical indexes, tumor stage, tumor imaging characteristics, previous treatment strategies and other clinical data before treatment were documented. Imaging examination follow-up results and adverse reactions during treatment were followed up until the end of follow-up or loss of follow-up or death. Kaplan-Meier method was used to analyze the clinical efficacy. Results: As of the last follow-up, 94 cases with mid-and advanced-stage HCC had received camrelizumab combined with apatinib as second-line treatment. Among them, 15 cases were lost to follow-up, 31 cases died, and 48 cases survived. The overall remission rate was 31.9%. The overall disease control rate was 71.3%. The median time to disease-free progression was 6.6 months. The median time to disease progression was not yet available. The 1-year cumulative survival rate was 62.3%. Grade 3 and above adverse reactions mainly included were thrombocytopenia (7.4%), abdominal pain (4.3%), active hepatitis (4.3%), leukopenia (4.3%), diarrhea (3.2%), hand-foot syndrome (3.2%). All adverse reactions were effectively controlled. Conclusion: Camrelizumab combined with apatinib can effectively prolong the survival period of patients with mid-and advanced-stage HCC, and it is well tolerated.

Abstract
Objective: To investigate the effect of body mass index (BMI) on clinical pregnancy and neonatal outcomes in patients with polycystic ovary syndrome (PCOS) during frozen-thawed embryo transfer. Methods: A total of 650 patients with PCOS who received routine in vitro fertilization or intracytoplasmic sperm injection treatment for frozen-thawed embryo transfer from June 2014 to June 2019 in Tianjin Central Hospital of Gynecology Obstetrics were retrospectively analyzed. According to BMI, PCOS patients were divided into group A (18.5≤BMI<23 kg/m2, n=253), group B (23≤BMI<25 kg/m2, n=167), and group C (BMI≥25 kg/m2, n=230). The general information, clinical pregnancy outcomes, pregnancy complications, the incidence of macrosomia and low-birth-weight infants were compared in the three groups, and the influencing factors of neonatal birth weight were analyzed. Results: The embryo implantation rate, clinical pregnancy rate, and ongoing pregnancy rate all showed downward trend with the increase of BMI, but the differences were not statistically significant (all P>0.05). The live birth rate in group C [47.0% (108/230)] was significantly lower than those in groups A and B, with statistical significance (χ²=7.43, P=0.024). The late miscarriage rate was higher in group C [9.4% (13/139)] than in groups A and B (χ²=7.66, P=0.022). The birth rates of macrosomia in groups B [22.2% (16/72)] and group C [21.1% (16/76)] were significantly higher than that in group A, and the difference was statistically significant (χ²=14.15, P=0.001). There was no statistically significant difference in the incidence of gestational diabetes between the three groups (χ²=3.81, P=0.149). The incidence of hypertension disorders complicating pregnancy increased with the increase of BMI, and the difference was not statistically significant (P>0.05). Regression analysis showed that macrosomia was significantly associated with maternal pre-pregnancy BMI and gestational weeks, and the risk of macrosomia increased by 15% (95%CI: 3%-28%) for every increase in maternal BMI. Conclusions: The embryo implantation rate, clinical pregnancy rate, and ongoing pregnancy rate of PCOS patients in frozen-thawed embryo transfer cycles show downward trend with the increase of BMI. Obese patients with PCOS have a significant increase in late miscarriage rate and a significant decrease in live birth rate. The incidence of hypertension disorders complicating pregnancy in PCOS patients in the obese group has an increasing trend, and the birth rate of macrosomia has increased significantly. Therefore, it is recommended that obese women with PCOS lose weight scientifically before pregnancy to improve pregnancy and neonatal outcomes.

Abstract
Objective: To investigate the impact of a previous cesarean delivery on pregnancy outcomes of in vitro fertilization and frozen-thawed embryo transfer (FET). Methods: The clinical data of 1 179 patients who received in vitro fertilization and FET in Tianjin Central Hospital of Gynecology Obstetrics from January 2014 to May 2019 and had a history of the previous delivery were retrospectively analyzed. The patients were divided into four groups according to different previous delivery history and the number of embryo transferred: group A (single embryo transfer group with cesarean delivery history, n=338), group B (single embryo transfer group with vaginal delivery history, n=78), group C (double embryo transfer group with cesarean delivery history, n=444), and group D (double embryo transfer group with vaginal delivery history, n=319). The 1∶1 propensity score based on age, body mass index (BMI), infertility duration, basal FSH, basal LH, number of oocytes retrieved and high-quality embryo rate was used to match group A and B (caliper value=0.15), group C and D (caliper value=0.05), and group A and C (caliper value=0.01) respectively to reduce the influence of selection bias. The clinical pregnancy outcomes of patients were compared. Results: (1) Group A and group B were single embryo transfer groups with a total of 77 pairs of matched patients. There were no statistically significant differences in clinical pregnancy rate [42.9% (33/77) vs 45.5% (35/77)], miscarriage rate, preterm birth rate, and neonatal birth weight (all P>0.05). (2) Group C and group D were double embryo transfer groups with a total of 304 pairs of matched patients. The clinical pregnancy rate [42.4% (129/304)] and twin pregnancy rate [9.5% (29/304)] of Group C were significantly lower than those of Group D [53.0% (161/304), 15.5% (47/304) respectively; both P<0.05). There were no statistically significant in miscarriage rate, preterm birth rate and neonatal birth weight between the two groups (all P>0.05). (3) Groups A and C matched 318 pairs of patients. The two groups had no statistical significances in clinical pregnancy rate [38.4% (122/318) vs 45.6% (145/318)], miscarriage rate and preterm birth rate (all P>0.05), but the twin pregnancy rate in group C was significantly higher than that of group A [11.3% (36/318) vs 0.3% (1/318), P<0.01). (4) The occurrence of the low-birth-weight infant were related to gestational age (OR=0.41, 95%CI: 0.32-0.54) and twin pregnancy (OR=4.44, 95%CI: 1.93-10.21), and the occurrence of macrosomia was related to BMI (OR=1.18, 95%CI: 1.06-1.32). Moreover, the previous delivery method was not related to the neonatal birth weight (P>0.05). Conclusions: Patients with different delivery histories receive FET therapy, the pregnancy outcomes of single embryo transfer are not significantly different, and the success rate of double embryo transfer in patients with a cesarean delivery history is low. The neonatal birth weight is not related to the history of the cesarean section. It is recommended that patients with a cesarean delivery history choose elective single embryo transfer to ensure the success rate and to reduce the risk.

Abstract
The homeostasis dysfunctions caused by cold stress remain a threat to intestinal health, particularly for young broiler chickens. We hypothesized that adenosine monophosphate-activated protein kinase (AMPK) was involved in the regulation of cold stress on intestinal health. This study aimed to examine the effect of cold stress for 72 h on growth performance, serum biochemistry, intestinal barrier molecules, and AMPK in broilers. A total of 144 10-day-old male Arbor Acres broilers were subjected to temperature treatments (control 28 ± 1 °C vs cold stress 16 ± 1 °C) for 72 h. Growth performance was monitored, serum was collected for the analysis of physiological parameters, and jejunal mucosa was sampled for the determination of tight junction (TJ) proteins, heat shock proteins, and AMPK signaling molecules. Results showed that 72 h cold treatment reduced average BW gain and increased the feed conversion ratio of the broilers (P < 0.05). Cold stress for 72 h increased blood endotoxin, aspartate aminotransferase, glucose, and low-density lipoprotein cholesterol levels (P < 0.05). Moreover, 72 h cold treatment up-regulated jejunal Occludin, zonula occludin 1, inducible nitric oxide synthase, heat shock factor 1, and AMPKα1 gene expression (P < 0.05) but had no obvious effect on total AMPK protein expression (P > 0.05). In conclusion, cold stress significantly reduced the growth performance of broiler chickens. The intestinal barrier function might be impaired, and enhanced bacterial translocation might occur. The unregulated gene expression of TJ proteins implied the remodeling of intestinal barrier. The change of AMPK suggested the possible relationship between intestinal energy metabolism and barrier function under cold stress.

Abstract
Objective: To detect the expression of Myc-induced nuclear antigen 53 (Mina53) and liver tissue >5 cm from the edge of the tumor (LTM5), and analyze its relationship with tumorigenesis, clinicopathological characteristics, and patient survival and prognosis in hepatocellular carcinoma (HCC). Methods: The expression levels of Mina53 mRNA and protein in 18 pairs of fresh HCC and LTM5 were assessed by qRT-PCR and Western blot, respectively. The expression of Mina53 in 284 pairs of HCC and LTM5 sample was determined by immunohistochemistry. Paired-sample t-test was used for the comparison of measurement data among groups, and heterogeneity of variance was tested using Wilcoxon rank-sum test. χ (2) test was used for the comparison of measurement data among groups. Kaplan-Meier method and log-rank test were used for survival analysis. Cox regression model was used for single factor and multi factor analysis. Results: The relative expression levels of Mina53 mRNA and protein in 18 fresh HCC tissues were significantly higher than those in LTM5 tissues (mRNA: -4.41 ± 1.48 and -5.93 ± 1.65, t = 3.100, P = 0.007; protein: 1.12 ± 0.29 and 0.46 ± 0.21, t = 10.616, P < 0.001). The relative expression level of Mina53 in 284 HCC tissues was higher than that of LTM5 (z = -18.739, P < 0.001). The expression level of Mina53 was associated with tumor size (χ (2) = 5.474, P = 0.019), vascular invasion (χ (2) = 8.965, P = 0.003), pathological grade (χ (2) = 12.006, P = 0.002), and TNM stage (χ (2) = 16.686, P < 0.001). The overall postoperative survival time and disease-free survival time of patients with high expression of Mina53 (28.5 months and 22.7 months, respectively) were shorter than those with low expression (33.0 months and 31.8 months, respectively) (P < 0.05) in HCC. Cox multivariate regression analysis showed that Mina53 and multiple tumors were independent prognostic factors affecting the overall postoperative survival time and disease-free survival time of HCC patients (P < 0.05). Conclusion: Mina53 may play an important role in the occurrence of HCC and participate in the process of tumor growth as well as invasion and metastasis. The high expression of Mina53 signifies that the patient has a poor prognosis and thus can be used as a potential marker for judging the prognosis of HCC patients.

Abstract
Objective: To evaluate the efficacy and safety of cell sheets containing allogeneic keratinocytes and fibroblasts in the treatment of partial-thickness burn wounds. Methods: The cell sheets containing allogeneic keratinocytes and fibroblasts were constructed using polyurethane biofilm as carrier. Then gross observation and histological observation were conducted. From April 2016 to December 2017, Changhai Hospital of Naval Medical University recruited patients with acute partial-thickness burn wounds that met the inclusion criteria for this prospective and positively self-controlled clinical trial. Recruitment of 40 acute partial-thickness burn wounds were planned with each selected single wound being not smaller than 10 cm×10 cm and not more than 5% total body surface area (TBSA). Each wound was equally divided into two areas, which were recruited into cell sheet group and conventional treatment group according to the random number table. The wounds in cell sheet group were covered by cell sheet and then sterile gauze as secondary dressings. Depending on the wound healing and exudation, the sterile gauze was replaced every 1 to 3 day (s) after the treatment was started, and the cell sheet was replaced every 7 days (namely dressing changing). The wounds in conventional treatment group were covered by sulfadiazine silver cream gauze and then dressed with sterile gauze, with the dressings changed every 2 to 3 days depending on wound exudation. On treatment day 5, 7, 10, and 14, the wound healing rates in the two groups were calculated. The complete wound healing time, the total number of dressing changes, and the status of wound infection during treatment were recorded. The Visual Analogue Scale was used to score the pain at the first dressing change. Scar formation of patients was followed up for 6 to 12 months after injury. Safety indicators including vital signs, laboratory examination indexes, and adverse reactions during treatment were observed. Data were statistically analysed with Wilcoxon rank sum test and Bonferroni correction. Results: (1) Each prepared cell sheet had a diameter of about 8 cm and was about 49 cm(2) in size, containing 2 or 3 layers of keratinocytes and fibroblasts. (2) A total of 43 patients were enrolled, of whom 3 patients dropped out of the study. Of the 40 patients who completed the treatment, there were 22 males and 18 females who were aged 1 to 57 year (s), with total burn area of 2% to 26% TBSA. (3) On treatment day 5, 7, 10, and 14, the wound healing rates in cell sheet group were significantly higher than those in conventional treatment group (Z=4.205, 4.258, 3.495, 2.521, P<0.05 or P<0.01). The complete wound healing time in cell sheet group was 7 (6, 8) days, which was significantly shorter than 11 (7, 14) days in conventional treatment group (Z=4.219, P<0.01). The total number of wound dressing changes in cell sheet group was 1 (1, 2) times, which was significantly less than 6 (4, 7) times in conventional treatment group (Z=5.464, P<0.01). (4) The wounds in cell sheet group in 31 patients healed before the first dressing change. The pain score of wounds in the first dressing change in cell sheet group of 9 patients was 1 (0, 1) point, while the pain score of wounds in the first dressing change in conventional treatment group of 40 patients was 2 (1, 3) points. There was no obvious infection in the wounds in both groups of 40 patients before the wound healing. Nine patients completed the follow-up after the trial. In 6 patients, no scar formation was observed in cell sheet group or conventional treatment group. The color of wounds in cell sheet group was consistent with normal skin, and there was only a small amount of pigment deposition in the wounds of conventional treatment group. Three patients developed pigment deposition only in the wounds of cell sheet group but obvious scars in conventional treatment group. (5) The abnormal fluctuations of vital signs including body temperature, blood pressure, heart rate, respiratory rate, and laboratory examination indexes of all patients during treatment were alleviated through the process of burn wound healing. No obvious adverse reactions or abnormalities related to the treatment were observed. Conclusions: The cell sheet containing allogeneic keratinocytes and fibroblasts can reduce the number of dressing changes, accelerate wound epithelialization, shorten wound healing time, reduce pain during dressing change in the treatment of partial-thickness burn wounds, and it may reduce scar hyperplasia after wound healing because of accelerating wound epithelization. Its clinical application is simple, safe, and effective.

Abstract
Objective: To investigate the protective effect of Baicalin on apoptosis induced by lipopolysaccharide in H9C2 cardiomyocytes and its possible mechanism. Methods: In order to establish apoptosis model of H9C2 cardiomyocytes, H9C2 cardiomyocytes were cultured and divided into four groups: the control group; the baicalin group was treated with baicalin at the final concentration of 10μmol/L for 12 hours; the LPS group was stimulated with LPS at the final concentration of 1 μg/ml for 6 hours; The LPS+baicalin group was stimulated with LPS at the final concentration of 1 μg/ml for 6 hours within treated with baicalin at the final concentration of 10μmol/L for 12 hours. Collecting cell samples, CCK-8 (The Cell Counting Kit-8) was used to detect cell activity, and Terminal-deoxynucleoitidyl Transferase Mediated Nick End Labeling (TUNEL) was used to detect the expression levels of apoptosis. Laser Scanning Confocal Microscopy was used to detect the expression levels of store-operated calcium entry in H9C2 cardiomyocytes. Western blot was used to detect the protein expression levels of STIM1, cleaved-caspase3, Bax and Bcl-2. Fluorogenic quantitative PCR was used to detect the mRNA expression level of STIM1. Results: Compared with the control group, LPS-induced H9C2 cardiomyocyte survival rate decreased (P<0.05), the expression level of apoptosis increased (P<0.05), the internal flow of calcium increased (P<0.05), the expression levels of cleaved-caspase3, Bax protein levels increased (P<0.05), Bcl-2 protein level decreased (P<0.05), the expression of STIM1 mRNA and protein level increased (P<0.05). Compared with LPS group, the survival rate of H9C2 cardiomyocytes in baicalin intervention group increased (P<0.05), the expression level of apoptosis decreased (P<0.05), the internal flow of calcium decreased (P<0.05), the expression levels of cleaved-caspase3, Bax protein decreased (P<0.05), and the level of Bcl-2 protein increased (P<0.05), the expression of STIM1 mRNA and protein level decreased (P<0.05). Conclusion: Baicalin may alleviate LPS-induced cardiomyocyte apoptosis by alleviating calcium overload, and improve cell survival.

Abstract
Objective: To preliminarily observe the effects of application of micro-negative pressure in children with small-area deep partial-thickness burn. Methods: From January 2016 to August 2018, 64 children with small-area deep partial-thickness burn who were admitted to the Department of Burn Surgery of the First Affiliated Hospital of Naval Medical University were recruited in this prospective randomized controlled study. According to the random number table, they were divided into negative pressure group [18 boys and 14 girls, aged (3.9±1.6) years with total burn area of (5.5±2.2)% total body surface area (TBSA)] and conventional group [20 boys and 12 girls, aged (3.8±1.7) years with total burn area of (5.8±1.6)% TBSA], with 32 patients in each group. After admission, simple debridement was performed in the patients of 2 groups. After that, the children in negative pressure group were treated with micro-negative pressure with negative pressure material replaced every 3 to 5 days. Children in conventional group were treated with silver sulfadiazine cream with dressing change every other day. On post injury day (PID) 14 and 21, general wound observation was performed, the wound healing rate was calculated, the exudates from the wounds were cultured and the positive detection rate was calculated. The number of patients requiring surgical skin grafting was recorded and the rate of surgical skin grafting was calculated, and the complete wound healing time was recorded in the patients of 2 groups. Scar formation was evaluated by the Vancouver Scar Scale (VSS) in 3, 6, and 12 months after wound healing. Data were processed with chi-square test, t test, Bonferroni correction, and analysis of variance for repeated measurement. Results: (1) On PID 14, all the necrotic tissue in the wounds of patients in negative pressure group was removed, with few exudates, and most of the wounds had been epithelialized; most of necrotic tissue in the wounds of patients in conventional group was removed, with more exudates and smaller wound healing area than those in negative pressure group. On PID 21, most of the wounds of patients in negative pressure group were healed, and the exudates were rare, while the wound healing area of patients in conventional group was significantly smaller than that in negative pressure group with more exudates. (2) On PID 14 and 21, the wound healing rates [(49.8±3.3)% and (95.8±2.4)%] of patients in negative pressure group were significantly higher than those in conventional group [(40.0±3.2)% and (75.3±2.5)%, t=11.899, 33.461, P<0.01]. (3) On PID 14 and 21, the positive detection rates of wound bacteria of patients in negative pressure group were significantly lower than those in conventional group (χ(2)=6.275, 5.741, P<0.05). (4) The rate of surgical skin grafting of patients in negative pressure group was significantly lower than that in conventional group (χ(2)=5.333, P<0.05). (5) The complete wound healing time of patients in negative pressure group [(23.9±2.3) d] was significantly shorter than that in conventional group [(27.9±1.8) d, t=-7.806, P<0.01]. (6) In 3, 6, and 12 months after wound healing, the VSS scores [(6.9±1.8), (5.6±1.4), (3.4±1.5) points] of patients in negative pressure group were significantly lower than those in conventional group [(9.0±1.5), (7.4±2.0), (5.7±1.6) points, t=-4.987, -4.127, -5.988, P<0.01]. Conclusions: In comparison with routine dressing change, the treatment of application of micro-negative pressure in children with small-area deep partial-thickness burn can significantly improve the wound healing rate and rate of surgical skin grafting, decrease the wound infection rate, shorten the wound healing time, and improve the wound healing quality.

Abstract
OBJECTIVE To investigate the relationship between the expression of nephrin and the infiltration of macrophages in renal tissues in patients with lupus nephritis (LN), and to provide the evidence of potential mechanism of podocyte injury in LN. METHODS In the study, 60 patients who were first diagnosed with LN by pathology were selected including 38 active LN patients with r-SLEDAI≥4, and another 10 patients of normal renal tissue were excised as a normal control group. The renal tissue and podocyte injury were observed through light and transmission electron microscope. The expression of nephrin and the infiltration of macrophages (CD68+cells) in the renal tissue of the 60 LN patients and 10 normal cases were detected by immunohistochemical and immunofluorescence method. Different statistical analysis methods were used to analyze the correlation between the variables. Variance analysis was used for comparison among the groups, while LSD test was used for comparison between every two groups. Pearson correlation analysis was used to analyze the correlation between the variables. RESULTS (1)Of all the LN patients, 24 h urinary protein [(3.94±1.76) vs. (1.56±0.68), P<0.05], erythrocyte sedimentation rate (ESR) [(79.83±6.3) vs. (40.1±10.5), P<0.05] and serum creatinine [(106.58±14.9) vs. (79.1±9.89), P<0.05] were significantly increased in active group than those in inactive group, while C3 [(0.34±0.12) vs. (0.78±0.11), P<0.05], C4 [(0.07±0.04) vs. (0.17±0.10), P<0.05 ] and eGFR [(62.42±5.16) vs. (81.33±4.53), P<0.05] were significantly decreased in active group. (2)Compared with the normal control group, the expression of nephrin in renal tissue of the LN patients was significantly decreased, and the expression of nephrin in the active patients was significantly lower than that in inactive group (P<0.05). (3)Compared with the normal control group, the number of infiltrated macrophages in the LN patients was significantly increased, especially in the active patients (P<0.05). Macrophages were mainly found in glomeruli. (4)There was a significant negative correlation between the expression of nephrin and macrophage infiltration in renal tissues of the LN patients (r=0.761, P<0.001). CONCLUSION Macrophage infiltration in renal tissues may be one of the potential mechanisms of podocyte injury in lupus nephritis.

Abstract
Objective: To assess the cognitive level of first aid knowledge regarding the small area burn among the child caregivers in Shanghai and improve the level of first aid for small area burn in children. Methods: From November 2017 to March 2018, 7 municipal districts in Shanghai were selected according to the random number table, from which 2 750 students of 4 nurseries, 5 kindergartens, 6 primary schools, and 2 junior middle schools were selected by adopting the convenience sampling method. Each student was limited to one caregiver as the research object. A cross-sectional survey was conducted on the cognitive level of first aid knowledge regarding small area burn among the caregivers with self-designed questionnaire through WeChat and Tencent QQ. The age, burn experience, and scarring after burns in children, the prevalence rate of burn in children of different age groups, the educational background of caregivers and their social relationship with their children, and the measures taken by caregivers firstly after small area burn occurred among their children were recorded. The choices of applying the folk prescription drugs to the wounds of their children made by caregivers and those with different educational backgrounds were recorded. The choices of applying daily necessities to the wound of their children made by caregivers were recorded. The caregivers' knowledge of standard first aid measures for small area burn, and the knowledge of caregivers with different educational backgrounds of all standard first aid measures for small area burn were recorded. The caregivers' choices of hospitals for treatment the first time, and the choices of going to the Grade Ⅲ Level A hospital with burn specialty for treatment made by caregivers with different knowledge levels about first aid measures for small area burn and those by caregivers whose children did or didn't have burn experience were recorded. The caregivers' choices of different types of medical institutions with burn specialty or specialized in burn treatment, and choices of going to burn department of comprehensive Grade Ⅲ Level A hospital for treatment made by caregivers with different knowledge levels about first aid measures for small area burn were recorded. Data were processed with Pearson chi-square test and partitions of chi-square test. Results: The effective recovery rate of questionnaire was 99.0% (2 723/2 750). The ages of children were mainly 6-11 years [64.7% (1 762/2 723)]The prevalence of burn in children was 19.4% (527/2 723). There was no statistically significant difference in the overall comparison of burn prevalence of children among the age groups (χ(2)=1.424, P>0.05). The percentage of scar formation after burn in children was 27.3% (144/527). The education backgrounds of caregivers were mainly undergraduate [40.2% (1 094/2 723)], and their social relationships with children were mainly children's mothers [74.6% (2 030/2 723)]. Assuming that their children suffered from minor burns, the measures firstly taken by 74.0% (2 016/2 723) of the caregivers was to immediately access cool running water and remove clothing on the wound of children. Totally 19.2% (523/2 723) of the caregivers chose to apply folk prescription drugs for their burn children by themselves, and the percentage of caregivers with education background of junior middle school choosing to apply folk prescription drugs for their burn children by themselves was significantly higher than that of caregivers with education background of junior college, undergraduate, or graduate (χ(2)=18.502, 20.642, 13.319, P<0.05). Totally 49.2% (1 340/2 723) of caregivers chose to daub many kinds of daily necessities for their burn children by themselves. Totally 39.2% (1 068/2 723) of caregivers knew all standard first aid measures for small area burn, the percentage of caregivers with education background of undergraduate knowing all standard first aid measures for small area burn was significantly higher than that of caregivers with education background of senior high school and secondary specialized school (χ(2)=11.234, P<0.05). Assuming that their children suffered from minor burns, 39.0% (1 063/2 723) of the caregivers chose to go to the nearest hospital for treatment the first time, the percentage of caregivers who knew all standard first aid measures for small area burn choosing to go to Grade Ⅲ Level A hospital with burn specialty for treatment the first time was similar with that of caregivers who did not know/did not fully know (χ(2)=3.528, P>0.05), and the percentage of caregivers whose children had burn experience choosing to go to Grade Ⅲ Level A hospital with burn specialty for treatment in the first time was similar with that of caregivers whose children didn't have burn experience (χ(2)=3.521, P>0.05). Among all medical institutions with burn specialty or specialized in burn treatment, 28.0% (762/2 723) of the caregivers chose to go to comprehensive Grade Ⅲ Level A hospital for treatment, and the percentage of caregivers who knew all standard first aid measures for small area burn choosing to go to comprehensive Grade Ⅲ Level A hospital for treatment was significantly higher than that of caregivers who did not know/did not fully know (χ(2)=4.890, P<0.05). Conclusions: The caregivers of children are mainly children's mothers with education background of undergraduate in Shanghai, and caregivers' cognitive levels of first aid knowledge regarding the small area burn are low. Only a few caregivers know all standard first aid measures for small area burn, and there are still some caregivers who have the wrong idea of applying folk prescription drugs or daily necessities for children by themselves. The publicity and education of basic first aid knowledge of burn should be strengthened through various channels such as burn simulation exercise and network, and caregivers should be guided to take their children to hospitals with burn specialty for treatment after occurrence of burn in children, so as to obtain more professional medical treatment.

Abstract
Objective: To investigate the short-term outcome of patients with acute myocardial infarction complicating cardiogenic shock due to left main disease. Methods: A total of 24 patients with acute myocardial infarction complicating cardiogenic shock due to left main artery disease hospitalized in Fuwai hospital from June 2012 to May 2018 were included. The clinical data were analyzed,and the patients were divided into survivor group (11 cases) and death group (13 cases) according to survival status at 28 days post the diagnosis of shock. The patients were further divided into thrombolysis in myocardial infarction(TIMI) flow grade 0-2 group (11 cases) and TIMI flow grade 3 group (13 cases) according to TIMI flow grade after the procedure. The patients were then divided into non-three-vessel lesions group (14 cases) and three-vessel lesions group (10 cases) according to coronary angiography results. Results: Compared with survivor group, patients in death group presented with lower worst systolic blood pressure within 24 hours after admission (50(48, 70) mmHg (1 mmHg=0.133 kPa) vs. 73(70, 80) mmHg, P<0.01), lower worst diastolic blood pressure with in 24 hours after admission ((33.5±12.4) mmHg vs. (48.9±9.4) mmHg, P<0.01), higher respiratory rates ((27.3±2.5) times/min vs. (21.5±4.0) times/min, P<0.01), less 24 hours urine output ((422±266) ml vs. (1 680±863) ml, P<0.01), lower platelet counts ((161.9±81.9)×10(9)/L vs. (241.6±94.0)×10(9)/L, P=0.03), higher serum creatinine ((250.0±36.8) μmol/L vs. (132.7±34.2) μmol/L, P<0.01), higher alanine aminotransferase (288(76,846) IU/ml vs. 81(42, 109) IU/ml, P=0.04), lower artery pH (7.11±0.17 vs. 7.39±0.09, P<0.01), higher lactic acid ((10.29±3.62) mmol/L vs. (4.21±2.85) mmol/L, P<0.01), higher incidence of invasive ventilation (7/13 vs. 2/11, P=0.02), higher scores of acute physiology and chronic health evaluation (APACHE) Ⅱ (35.4±6.8 vs. 18.7±1.7, P<0.01) and simplified acute physiology score (SAPS) Ⅱ (73.5±17.4 vs. 47.0±4.3, P<0.01), and higher incidence of target vessel TIMI flow grade 0-2 (10/13 vs. 1/11, P<0.01). Kaplan-Meier survival curve analysis showed that survival rate at 28 days post the diagnosis of shock in TIMI flow grade 3 group was higher than that in TIMI flow grade 0-2 group (76.9% vs. 9.1%, log-rank test, P<0.01), and mortality rate was similar at 28 days post the diagnosis of shock between non-three-vessel lesions group and three-vessel lesions group (35.7% vs. 60.0%, log-rank test, P=0.14). Multivariate logistic regression analysis showed that compared with TIMI flow grade 0-2 group, the OR value of death at 28 days post the diagnosis of shock in TIMI flow grade 3 patients with acute myocardial infarction complicating cardiogenic shock due to left main disease was 0.030(95%CI 0.003-0.340, P<0.01). Conclusion: Short-term outcomeof patients with acute myocardial infarction complicating cardiogenic shock due to left main disease remains poor, and final flow of TIMI grade 3 is confirmed as independent protective factor of death at 28 days post the diagnosis of shock in these patients.

Abstract
Objective: To explore the management strategy and clinical outcome of renal transplantation in presensitized recipients using deceased donor kidneys. Methods: From January 2011 to June 2018, twenty-one presensitized patients, including 8 with positive donor specific antibodies (DSA) and 13 with positive panel-reactive antibodies (PRA) but no DSA, received renal retransplantation from deceased donors in our center. The incidence of delayed graft function (DGF) and acute rejection (AR), changes of DSA, and the graft and patient survival were retrospectively analyzed. Results: None of the renal allografts had primary non-function (PNF) and DGF after transplantation. Four of the 13 recipients with PRA(+)/DSA-had a total of 5 episodes of acute cell-mediated rejection (CMR), while 5 of 8 recipients with pre-existing DSA(+) developed AR, including 3 cases with CMR alone and 2 cases with mixed AR. All episodes of rejection were successfully reversed after targeted treatment. Interestingly, of the 8 recipients with positive preformed DSA, 4 cases with positive DR-DSA and/or class Ⅰ-DSA had their DSA disappeared after transplantation, whereas DQ-DSA remained positive in 4 of 5 recipients. After a median follow-up of 26 months, all recipients maintained normal renal allograft function, and the survival rates of both graft and recipient were 100%. Conclusions: With the use of deceased donors, kidney transplantation can be successfully performed in presensitized patients by appropriate HLA-matching screening, choosing donor kidneys with good quality, and the combination of optimal perioperative treatment.

Abstract
Objective: To compare the predictive value of PSS, APACHEII, SAPSII and SOFA in the prognosis evaluation of acute poisoning. Methods: Clinical data (including PSS score, APACHEII score, SAPSII score and SOFA score, within 24 hours after admission) of 231 acute poisoning patients admitted to the emergency intensive care unit EICU of our hospital from January 2015 to October 2016 was retrospectively analyzed. The patients were divided into the survival group and the dead group according to the 28-day clinical outcomes, comparing the differences of clinical data in each group. To analyze the correlation between PSS score, APACHEII score, SAPSII score and SOFA score in each group, comparing the value and the area under the ROC curve of four scoring systems and evaluate the predictive value of the four scoring systems. Results: Comparing with the survival group and the dead group, PSS score, APACHEII score, SAPSII score and SOFA score were significantly different (P<0.01) . PSS score, APACHEII score, SAPSII score and SOFA score were significantly positive correlation (P<0.01) , the area under the ROC curve (AUC) of the four scoring systems were 0.833, 0.887, 0.843 and 0.843 respectively. The area under the ROC curve (AUC) of APACHEII score was higher than PSS score, SAPSII score and SOFA score, the difference was statistically significant (z=2.351, 2.317, 2.217; P=0.019, 0.021, 0.027) , there was no significant difference in the area (AUC) between the three scoring curves (P>0.05) . The cutoff value (cut-off) , sensitivity, specificity and accuracy rates of PSS score, APACHEII score, SAPSII score and SOFA score were (2.5, 93.1%, 50.9%, 61.5%) , (14.5, 82.8%, 75.7%, 77.48%) , (31.5, 77.6%, 76.90%, 77.08%) , (5.5, 77.60%, 74.60%, 75.35%) . Conclusion: PSS score, APACHEII score, SAPSII score and SOFA score can evaluate the prognosis of patients with acute poisoning, but the APACHEII score is better than the other three scoring systems in evaluating the prognosis for its evaluation ability and accuracy rate.

Abstract
Dysfunction of the intestinal epithelial barrier under elevated temperatures is assumed to prompt pathological conditions and to eventually impede chickens' growth, resulting in massive economic losses in broiler industries. The aims of this research were to determine the impact of acute heat stress on the intestinal tight junction network of broiler chicks (Gallus domesticus L.) and to elucidate whether adenosine monophosphate-activated protein kinase (AMPK) was involved in the integrated response of the broiler's gastrointestinal tract to heat stress. A total of 80 9-day-old Arbor Acres chicks were subjected to temperature treatment (thermoneutral versus heat stress) and AMPK inhibition treatment (5 mg/kg body weight intraperitoneal injection of compound C vs. sham treatment) for 72 h. In addition to monitoring growth performance, the mRNA and protein levels of key tight junction proteins, target components of the AMPK pathway, and biomarkers of intestinal inflammation and oxidative stress were assessed in the jejunum under both stressors at 24 and 72 h. An increase of the major tight junction proteins, claudin-1 and zonula occludens-1, was implemented in response to an exacerbated expression of the AMP-activated protein kinase. Heat stress did not affect zootechnical performance but was confirmed by an increased gene expression of heat shock proteins 70 and 90 as well as heat shock factor-1. In addition, hyperthermia induced significant effects on tight junction proteins, although it was independent of AMPK.

Abstract
The kinetics of serum hepatitis B surface antigen (HBsAg) during the natural history of hepatitis B virus (HBV) infection has been studied, but the factors affecting them remain unclear. We aimed to investigate the factors affecting HBsAg titres, using data from multicentre, large-sized clinical trials in China. The baseline data of 1795 patients in 3 multicentre trials were studied, and the patients were classified into 3 groups: hepatitis B early antigen (HBeAg)-positive chronic HBV infection (n = 588), HBeAg-positive chronic hepatitis B (n = 596), and HBeAg-negative chronic hepatitis B (n = 611). HBsAg titres in the different phases were compared, and multiple linear progression analyses were performed to investigate the implicated factors. HBsAg titres varied significantly in different phases (P = .000), with the highest (4.60 log10 IU/mL [10%-90% confidence interval: 3.52 log10 IU/mL-4.99 log10 IU/mL]) in patients with HBeAg-positive chronic HBV infection. In all phases, age and HBV DNA were correlated with serum HBsAg level. In HBeAg-positive chronic hepatitis B patients, a negative correlation between HBsAg titres and fibrosis stage was observed. Alanine amonitransferase or necroinflammatory activity was also correlated with HBsAg titres in HBeAg-negative chronic hepatitis B patients. In conclusion, decreased HBsAg titres may be associated with advancing fibrosis in HBeAg-positive chronic hepatitis B patients or increased necroinflammation in those with HBeAg-negative chronic hepatitis B. Our findings may help clinicians better understand the kinetics of HBsAg and provide useful insights into the management of this disease.

Abstract
In this article, multiple eigen-systems including linear growth rates and eigen-functions have been discovered for the Rayleigh-Taylor instability (RTI) by numerically solving the Sturm-Liouville eigen-value problem in the case of two-dimensional plane geometry. The system called the first mode has the maximal linear growth rate and is just extensively studied in literature. Higher modes have smaller eigen-values, but possess multi-peak eigen-functions which bring on multiple pairs of vortices in the vorticity field. A general fitting expression for the first four eigen-modes is presented. Direct numerical simulations show that high modes lead to appearances of multi-layered spike-bubble pairs, and lots of secondary spikes and bubbles are also generated due to the interactions between internal spikes and bubbles. The present work has potential applications in many research and engineering areas, e.g., in reducing the RTI growth during capsule implosions in inertial confinement fusion.

Abstract
Objective: To study the antiseptic effect of compound lysostaphin disinfectant and its preventive effect on infection of artificial dermis after graft on full-thickness skin defect wound in rats. Methods: (1) Each one standard strain of Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus were selected. Each 20 clinical strains of Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus were collected from those isolated from wound exudates of burn patients hospitalized in our wards from January 2014 to December 2016 according to the random number table. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of compound lysostaphin disinfectant to above-mentioned strains were detected. The experiment was repeated 3 times. Compared with the corresponding standard strain, the clinical strain with higher MIC and/or MBC was considered as having decreased sensitivity to the disinfectant. The percentage of strains of each of the three kinds of bacteria with decreased sensitivity was calculated. (2) Artificial dermis pieces were soaked in compound lysostaphin disinfectant for 5 min, 1 h, 2 h, and 4 h, respectively, with 21 pieces at each time point. After standing for 0 (immediately), 12, 24, 36, 48, 60, 72 h (with 3 pieces at each time point), respectively, the diameters of their inhibition zones to standard strains of Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus were measured. The experiment was repeated 3 times. The shortest soaking time corresponding to the longest standing time, after which the disinfectant-soaked artificial dermis could form an effective inhibition zone (with diameter more than 7 mm), was the sufficient soaking time of the disinfectant to the artificial dermis. (3) Forty Sprague-Dawley rats were divided into post injury day (PID) 3, 7, 14, and 21 sampling groups according to the random number table, with 10 rats in each group. A full-thickness skin defect wound with a diameter of 20 mm was made on both sides of the spine on the back of each rat. Immediately after injury, the artificial dermis without any treatment was grafted on the wound on left side of the spine (hereinafter referred to as control wound), while the sufficiently soaked artificial dermis with compound lysostaphin disinfectant was grafted on the wound on right side of the spine (hereinafter referred to as disinfectant wound). On PID 3, 7, 14, and 21, the gross condition of wounds of all the surviving rats was observed, and the new infection rates of control wounds and disinfectant wounds were calculated. Then, the rats in the sampling group with corresponding time were killed, and the full-thickness wound tissue containing artificial dermis was collected for quantitative analysis of bacteria. Bacteria content of the uninfected control wounds and that of the uninfected disinfectant wounds were compared. Data were processed with chi-square test and Wilcoxon rank sum test. Results: (1) The MIC of compound lysostaphin disinfectant to standard strains of Staphylococcus aureus, Klebsiella pneumoniae, and Acinetobacter baumannii were 1/32, 1/32, and 1/512 of the original concentration of the disinfectant, respectively, and the MBC were 1/32, 1/16, and 1/512 of the original concentration of the disinfectant, respectively. The percentages of clinical strains of Klebsiella pneumoniae, Acinetobacter baumannii and Staphylococcus aureus with decreased sensitivity to compound lysostaphin disinfectant were 15% (3/20), 20% (4/20), and 10% (2/20), respectively. (2) After being soaked in compound lysostaphin disinfectant for 2 and 4 h, the longest standing time, after which the artificial dermis could form an effective inhibition zone against Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus, were 24, 36, and 48 h respectively, longer than 12, 24, and 24 h of soaking for 5 min and 24, 24, and 36 h of soaking for 1 h. The sufficient soaking time of compound lysostaphin disinfectant to artificial dermis was 2 h. (3) On PID 3, no infection symptom was observed in all the wounds, and so both the new infection rate of control wounds and that of disinfectant wounds were 0. The artificial dermis was transparent but not well connected with the wound. On PID 7, the new infection rate of control wounds was 20.00% (6/30), which was obviously higher than 3.33% (1/30) of disinfectant wounds, χ(2)=4.043, P<0.05. On the infected wound, a large amount of purulent exudates were observed, and the artificial dermis was not connected with the wound and degraded partially. On the uninfected wound, artificial dermis was transparent and had a partial connection with the wound. On PID 14 and 21, no new infected wound was observed, and so both the new infection rate of control wounds and that of disinfectant wounds were 0. There was no obvious improvement on the infected wounds. The collagen layers of artificial dermis in the uninfected wound established a good connection with the wound and were separating from the silica gel layer gradually. Infection occurred in 2, 3, 1 control wound (s) in PID 7, 14, and 21 sampling groups, respectively, and in 1 disinfectant wound in PID 14 sampling group. The bacteria content of the infected wounds tissue was 0.79×10(6) to 7.22×10(9) colony-forming unit (CFU)/g. The bacteria content of uninfected control wounds tissue in PID 3, 7, and 14 sampling groups were (3.43±1.88)×10(2,) (2.37±0.43)×10(3,) and (8.40±1.03)×10(3) CFU/g, respectively, which were significantly higher than (0.33±0.12)×10(2,) (0.43±0.17)×10(3,) (2.16±0.52)×10(3) CFU/g of uninfected disinfectant wounds tissue (Z=-3.780, -3.554, -3.334, P<0.05). The bacteria content of uninfected control wounds tissue and that of uninfected disinfectant wounds tissue in PID 21 sampling group were similar (Z=-0.490, P>0.05). Conclusions: Compound lysostaphin disinfectant has quite strong antibacterial ability against Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus. Clinical strains of the three kinds of bacteria were highly sensitive to compound lysostaphin disinfectant. Saturation of absorption of compound lysostaphin disinfectant achieves in artificial dermis after 2 hours' soaking. After 24, 36, and 48 hours' standing, the soaked artificial dermis still has the antibacterial effect on Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus, respectively. The infection rate and the bacteria content of full-thickness skin defect wound in rats are all decreased when grafted with soaked artificial dermis.

Abstract
OBJECTIVE To investigate the current situation of the activities of daily living (ADL) of the aged at home in western China, and to analyze its influencing factors so that we can improve the quality of life and pension services of elderly people. METHODS The elderly people who came from Qinghai Province, Ningxia Autonomous Region, Xinjiang Uygur Autonomous Region, Shanxi Province, Guizhou Province, Guangxi Province, Sichuan Province, Yunnan Province and Chongqing were surveyed by questionnaires. Logistic regression model was used to analyze the influencing factors of ADL. RESULTS A total of 7 175 aged people living in the western China were surveyed. In the study, 78.86% of the aged at home could independently live. 12.32% of the aged were of mild dysfunction. 6.27% of the aged had moderate dysfunction. And 2.55% of the aged suffered severe dysfunction. Multiple Logistic analyses indicated that age, educational level, economic income, body mass index and disease were the factors that affected their ADL. The risk of decreased ADL in the 60-69 and 70-79year-old groups were 0.221 (95%CI: 0.190-0.258) and 0.353 (95%CI: 0.305-0.409) times that of the elderly over the age of 80. Compared with illiterate seniors,the risks of decline in ADL of primary school, junior high school, secondary or high school, college or undergraduates, postgraduates or above were 0.299 (95%CI: 0.140-0.637), 0.312 (95%CI: 0.146-0.663), 0.238 (95%CI: 0.112-0.510), 0.226 (95%CI: 0.105-0.484), and 0.238 (95%CI: 0.110-0.514) times. The declines in the risk of ADL for elderly people with quite difficult economic conditions, slight difficulty and breaking even were 2.720 (95%CI: 2.015-3.672), 2.344 (95%CI: 1.816-3.027), and 1.542 (95%CI: 1.215-1.957) times of the economically abundant people. Compared with those with a body mass index (BMI)≥28, the risk of ADL reduction for BMI<18.5 was 1.577 (95%CI: 1.142-2.179) times. And the ADL of the elderly with no disease was at the risk of falling 0.685 (95%CI: 0.602-0.779) times that of an elderly person with the disease. CONCLUSION The activities of daily living of age at home of western China are not high, and affected by many factors, such as age, educational level and so on. With the increasing of the elderly, maintaining and improving the ADL are the problems and challenges that we are faced with.

Abstract
Objective: To investigate the role of FibroScan(FS)in liver fibrosis evaluation in patients with chronic hepatitis B virus(HBV)infection and related influencing factors. Methods: A total of 313 patients with chronic HBV infection were enrolled, and liver tissue was obtained through ultrasound-guided"1-second fast tissue cutting". The liver stiffness measurement(LSM)was determined by FS, serum HBeAg and liver function were measured, and the patients' demographic data were recorded. The t-test was used for comparison of normally distributed data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed data between groups; the Spearman or Pearson correlation coefficient was used for correlation analysis; the ROC curve and AUC were used to evaluate the efficiency of FS in the diagnosis of liver fibrosis ≥S2. Results: LSM was positively correlated with liver inflammation grade and fibrosis stage(r = 0.428 and 0.402 in HBeAg-positive group and r = 0.296 and 0.283 in HBeAg-negative group, all P < 0.001). The correlation of LSM with sex, age, alanine aminotransferase(ALT)level, and total bilirubin(TBil)was affected by HBeAg status and ALT level, and LSM was only positively correlated with TBil in HBeAg-negative group(r = 0.298, P < 0.001). In patients with ALT ≥2×upper limit of normal(ULN), FS had a low efficiency in the diagnosis of liver fibrosis ≥S2(AUC < 0.75, P > 0.05), regardless of their HBeAg status. The cut-off values of FS in the diagnosis of liver fibrosis ≥S2 varied with ALT level and HBeAg status, and in the ALT <1×ULN and 1-2×ULN groups, the cut-off values of FS in the diagnosis of liver fibrosis ≥S2 in patients with positive and negative HBeAg were 5.85 kPa/7.3 kPa and 6.35 kPa/8.5 kPa, respectively. In the patients with positive HBeAg in ALT < 2×ULN group, LSM was positively correlated with age(r = 0.278, P = 0.014). FS had relatively high diagnostic efficiency in patients aged > 30 years(AUC = 0.867, P < 0.001)and low diagnostic efficiency in patients aged≤30 years(AUC = 0.632, P > 0.05). Conclusion: LSM is positively correlated with liver inflammation grade and fibrosis stage. The cut-off value of FS in the diagnosis of marked liver fibrosis is affected by age, ALT level, and HBeAg status. FS has low diagnostic efficiency in patients aged ≤30 years.

Abstract
Objective: To investigate the safety and feasibility of mini-flank open nephron sparing surgery (MI-OPN) via retroperitoneal route for the treatment of centrally located renal tumor. Methods: From May 2013 to April 2015, twenty-four cases of centrally located renal tumor were treated with MI-OPN via retroperitoneal route in Zhongshan Hospital. All cases were included in this study with whose clinical data and long term follow-up information retrospectively analyzed. Results: With the assistance of intraoperative ultrasonography to confirm tumor location and boundary, MI-OPN was successfully performed in all cases. Mean tumor maximum diameter was 3.3±0.6 cm, mean operation time was 113±16 minutes, mean ischemia time was 31±6 min, and mean estimated blood loss was 102±46 ml. Mean postoperative hospital stay was 5.0±0.8 days, postoperative complication was found in one patient (4%). The mean pre- and postoperative serum creatinine were 77.1±20.1 μmol/L and 90.3±20.0 μmol/L. Pathological examination confirmed negative surgical margin in all cases, with 18 cases of clear cell renal cell carcinoma, 2 cases of papillary renal cell carcinoma, 2 cases of chromophobe renal carcinoma, 1 case of renal oncocytoma and 1 case of renal angiomyolipoma. In up to 12-36 months postoperative follow-up, no local recurrence or systemic progression was witnessed. Conclusions: For the treatment of centrally localized renal tumor, MI-OPN via retroperitoneal route is a safe and feasible operation method. Importantly, rupture of the tumor capsule was effectively avoided during tumor resection with the assistance of ultrasonic position-setting. Furthermore, incidence of severe postoperative complications such as bleeding and damage of collection system were not found since surgical wound of kidney sewn tightly and finely. The last but not the least, by placing ice slush in retroperitoneal cavity, impairment of renal function caused by renal artery clamping can be alleviated due to decreased metabolism.

Abstract
Objective: To investigate the prevalence, severity of hearing disorders and demographics of people with hearing disorders based on the whole population in Jilin, Guangdong, Shannxi and Gansu provinces in China. Methods: According to " WHO Ear and Hearing Disorders Survey Protocol" , 144 clusters were chosen with probability proportional sampling(PPS) method from the four provinces covering 194, 688, 061 residents. Audiological test, otological examination and questionnaire surveying were conducted for all samples from August, 2014 to September, 2015. The hearing disorders were classified according to WHO criteria and classification. Results: Among 47 511 targeted residents, 45, 052 individuals (94.82% response rate) participated in the survey. The standardized prevalence rates of hearing disorders and disabling hearing disorders were 15.84 % and 5.17 % respectively. Almost 50% of people with hearing disorders had no awareness of it or its starting time. There was significant difference in the prevalence among people of different ages, genders, occupations, provinces, marital status and education levels. The prevalence of hearing disorders increased significantly as age grew. People above 60 years old occupied 55.31% of the total hearing disorders. The prevalence of hearing disorders among male, people of low education and those who lost husband or wife, as well as workers and farmers was relatively higher. Conclusions: The prevalence of hearing disorders is high, and hearing disorders are " invisible" . Demographics and socioeconomic factors significantly influence the prevalence of hearing disorders.

Abstract
Objective: To evaluate the safety and efficacy of mini-flank incision for open partial nephrectomy for stage T1b renal tumor. Methods: The data of patients with stage T1b renal tumor who underwent mini-flank incision for open partial nephrectomy between January 2010 to September 2015 were retrospectively reviewed. The Nephron-sparing surgery (NSS) was performed through mini-flank supra-12th rib incision under general anesthesia. Results: A total of 47 patients(31 male and 16 female) were enrolled in our study. The median age was 40 years (range 22-67 years). The Zhongshan Score(ZS score) of renal tumors was 6 in 5 cases, 7 in 13 cases, 8 in 12 cases, 9 in 5 cases, 10 in 6 cases, 11 in 2 cases, 12 in 2 cases, 13 in 2 cases. The length of incision was from 7 cm to 9 cm, with an average of 8.1 cm. The operative time was from 70 min to 150 min, with an average of 96 min. The blood loss was from 50 ml to 600 ml, with an average of 135 ml. The warm ischemia time was from 20 min to 35 min, with an average of 28 min. All of the surgery margin were negative. One patient had fluid in surgical region and relieved after the drainage, and one patient had acute myocardial infarction. The hospital stay time was from 5 d to 14 d, with an average of 8 d. The pathological diagnosis included clear cell carcinoma in 37 cases, multilocular cystic renal carcinoma in 1 case, chromophobe cell tumor in 4 cases, and papillary carcinoma in 5 cases. The mean preoperative serum creatinine level was 87 μmol/L(48-150 μmol/L) and with a mean of 91 μmol/L(52-148 μmol/L) at 3 month follow-up after surgery, and there was no difference between the preoperative and postoperative period(P>0.05). A total of 45 out of 47 patients were followed up for 36 to 78 months, with an average of 60 months, and no one had recurrence or metastasis during follow-up. Conclusion: Mini-flank incision for open partial nephrectomy for renal tumor with stage T1b is safe and effective, which is worthy of promotion and application for small incision and quick recovery.

Abstract
In the missionary hospitals founded in the nineteenth century by the missionaries in China, the sprout of consciousness of medical risk control emerged. They did their best to avoid medical accidents which might lead to anti-missionary struggle by the Chinese people, and were especially cautious to control the happening of medical accidents. First of all, the hospitals made careful screening on patients by giving priority to those patients pursuing treatment of eye diseases, and barely forced to accept patients with intractable and critical diseases. Second, before the operation, the missionary doctors usually let the patient sign an agreement of consent for surgical operation, with the patient him/herself responsible for all the consequences of operation. Generally, the patient(s) won't be hospitalized, even though the work of their nursing was generally done by the patient's relatives. All these three initiatives promoted the spread of western medicine in China and expanded a positive influence of western medicine, though it seemed to be contradictory to the principles of equality and universal love of Christianity.

Abstract
In the present study, we examined whether the ARNTL (BMAL1) rs2278749 T/C polymorphism was associated with the susceptibility to Alzheimer disease (AD). This case-control study examined the genotypes of apolipoprotein E (APOE e4) and BMAL1 rs2278749 T/C using restriction fragment length polymorphism and the TaqMan assay, respectively. A total of 296 unrelated AD patients and 423 control subjects were included. Both in the entire sample and in APOE e4 non-carriers, the prevalence of T carriers in BMAL1 rs2278749 T/C in AD patients was significantly higher than that in control subjects (entire sample: χ(2) = 12.950, P < 0.0001; APOE e4 non-carriers: χ(2) = 13.094, P < 0.0001). Both in the entire sample and in APOE e4 non-carriers, the prevalence of TT genotypes 2278749 in AD patients was also significantly higher than that in control subjects (entire sample: χ(2) = 7.765, P = 0.024; APOE e4 non-carriers: χ(2) = 13.062, P < 0.0001). However, among APOE e4 carriers, the difference in the prevalence of T carriers or TT genotypes in the BMAL1 rs2278749 T/C between patients and control subjects presents was not significant (T carriers: χ(2) = 0.078, P = 0.851 or TT genotypes: χ(2) = 2.576, P = 0.325). Among APOE e4 non-carriers, T carriers in the BMAL1 rs2278749 T/C were associated with a high susceptibility to AD, but among APOE e4 carriers, the association between AD and BMAL1 rs2278749 T/C was not significant.

Abstract
Camellia oleifera is an important edible oil woody plant in China. Lack of useful molecular markers hinders current genetic research on this tree species. Transcriptome sequencing of developing C. oleifera seeds generated 69,798 unigenes. A total of 6949 putative microsatellites were discovered among 6042 SSR-containing unigenes. Then, 150 simple sequence repeats (SSRs) were evaluated in 20 varieties of C. oleifera. Of these, 52 SSRs revealed polymorphism, with the number of alleles per locus ranging from 2 to 15 and expected heterozygosity values from 0.269 to 0.888. The polymorphic information content varied from 0.32 to 0.897. Cross-species transferability rates in Camellia chekangoleosa and Camellia japonica were 90.4 and 78.8%, respectively. The 52 polymorphic unigene-derived SSR markers serve to enrich existing microsatellite marker resources for C. oleifera and offer potential for applications in genetic diversity evaluation, molecular fingerprinting, and genetic mapping in C. oleifera, C. chekangoleosa, and C. japonica.

Abstract
To investigate the role of apoptosis in duck viral hepatitis pathogenesis, 4- and 21-d-old ducks were inoculated with duck hepatitis A virus serotype 1 and killed at 2, 6, 12, 24, and 48 h postinfection. TdT-mediated dUTP nick-end labeling was used to detect apoptosis cells. Expression profiles of apoptosis-related genes including caspase-3, -8, -9, and Bcl-2 in spleen, bursa of Fabricius, liver, and the quantity of virus in blood were examined using real-time PCR. The TdT-mediated dUTP nick-end labeling analysis indicated there was a significant difference of apoptotic cells between treatments and controls. The same difference also appeared in virus amount variation in blood during infection. Gene expression analysis revealed that the apoptosis-related gene expression profile was different in the 2 groups, and also different between various organs. This study suggested that apoptosis may play an important role in duck hepatitis A virus serotype 1 infection, and apoptosis suppression might facilitate virus multiplication, resulting in the highest virus concentration in the host.

Abstract
CN17 is a functional stay-green wheat variety that exhibits delayed leaf senescence and enhanced photosynthetic competence. To better understand these valuable traits, levels of chlorophyll a and b, soluble proteins, unsaturated fatty acids, and other components of CN17 were assayed. In addition, chloroplast ultrastructure, chloroplast number, and differences in gene expression between CN17 and a control variety, MY11, were examined. By 21 d post-anthesis (DPA), CN17 leaves exhibited a significantly higher maximal photochemical efficiency for photosystem II (PSII) (F(v) /F(m) ) and a significantly higher efficiency of excitation capture by open PSII reaction centres (F(v) '/F(m) '). In addition, chlorophyll degradation in CN17 was delayed by approximately 14 d, and was not blocked as observed in cosmetic stay-green phenotypes. The soluble protein content (Ps) of CN17 was higher than MY11 at all timepoints assayed, and the ratio of unsaturated to saturated fatty acids was significantly higher. CN17 also exhibited isolated granal lamellae associated with vesicles and diminished peroxidation, and between 35 and 42 DPA, a sharp decrease in chloroplast number was detected. Taken together, these results strongly support the hypothesis that chloroplast ultrastructure regeneration is responsible for the functional stay-green trait of CN17, and gene expression data provide insight into the mechanistic details.

Abstract
ABSTRACT Although copper is an essential metal and cadmium is an environmental pollutant, both are toxic when present in excess. Metallothionein and glutathione are two of the key components that participate in detoxification of copper and cadmium. In the present study the role of glutathione in resistance to copper and cadmium was investigated with the yeast Saccharomyces cerevisiae. The yeast cells used in this study have different abilities to produce glutathione and Cup1 protein, the yeast metallothionein homolog encoded by CUP1 gene. It was demonstrated that Cup1 protein plays a dominant role in buffering excess copper, and yeast does not depend on glutathione to reduce copper toxicity whether it possesses single or multiple copies of CUP1. In fact, excess copper can cause glutathione oxidation and depletion and damage the glutathione system. On the other hand, it was indicated that Cup1 protein is an important cadmium-detoxifying component, and the glutathione system can positively respond to cadmium. In yeast containing single or multiple copies of CUP1, glutathione is an indispensable line of defense against cadmium. Yeast having glutathione and no Cup1 protein is not able to grow in medium containing excess copper, but can tolerate higher concentrations of cadmium. In addition, it was found that yeast, independent of glutathione, can efficiently remove excess copper, whereas it cannot promptly eliminate accumulated cadmium regardless of having glutathione or not.

Abstract
In the title compound, [Cd(C8H4O5)(C12H12N2)], the CdII cation is coordinated by three 5-hydroxyisophthalate anions and one 5,5′-bimethyl-2,2′-bipyridine ligand in a distorted CdO4N2 octahedral geometry. The 5-hydroxyisophthalate anions bridge the Cd cations, forming a two-dimensional polymeric complex parallel to (100). In the complex, the hydroxy group is linked to the uncoordinated carboxy-O atom via an O—H⋯O hydrogen bond. Weak C—H⋯O hydrogen bonds are also present in the crystal structure. One of the methyl groups is disordered over two positions in a 0.536 (11):0.464 (11) ratio.

Abstract
The behavior of tethered DNA in shear flow is investigated numerically by the smoothed dissipative particle dynamics (SDPD) method. Unlike numerical methods used in previous studies, SDPD models the solvent explicitly, takes into account the fully coupled hydrodynamic interactions and is free of the numerical artifact of wall sticking. Based on numerical simulations the static and dynamic properties of a tethered DNA is studied both qualitatively and quantitatively. The observed properties are in general agreement with previous experimental, numerical and theoretical work. Furthermore, the cyclic-motion phenomenon is studied by power spectrum density and cross-correlation function analysis, which suggest that there is only a very weak coherent motion of tethered DNA for a characteristic timescale larger than the relaxation time. Cyclic motion is more likely relevant as an isolated event than a typical mode of DNA motion.

Abstract
The crystal structure of the title compound, (C16H13FN)[Ni(C3S5)2], consists of NiIII complex anions and 1-(2-fluorobenzyl)quinolinium (fbq) cations. In the complex anion, the NiIII cation is chelated by two 2-sulfanylidene-1,3-dithiole-4,5-dithiolate (dmit) dianions in a distorted square-planar geometry; the two dmit mean planes are twisted with respect to each other at a dihedral angle of 8.44 (3)°. In the fbq cation, the dihedral angle between the benzene ring and the quinoline ring system is 80.57 (14)°. The centroid–centroid distance of 3.860 (5) Å between benzene rings indicates π–π stacking between adjacent fbq cations. The distance of 3.4958 (18) Å between the S atom and the centroid of the pyridine ring suggests the existence of a lone-pair–aromatic interaction between the anion and the cation. A short S⋯S contact [3.387 (2) Å] is also observed in the crystal structure.

Abstract
Stripe rust, caused by Puccinia striiormis Westend f. sp. tritici, is one of the most important foliar diseases of wheat (Triticum aestivum L.) worldwide. Stripe rust resistance genes Yr27, Yr31, YrSp, YrV23, and YrCN19 on chromosome 2BS confer resistance to some or all Chinese P. striiormis f. sp. tritici races CYR31, CYR32, SY11-4, and SY11-14 in the greenhouse. To screen microsatellite (SSR) markers linked with YrCN19, F1, F2, and F3 populations derived from cross Ch377/CN19 were screened with race CYR32 and 35 SSR primer pairs. Linkage analysis indicated that the single dominant gene YrCN19 in cultivar CN19 was linked with SSR markers Xgwm410, Xgwm374, Xwmc477, and Xgwm382 on chromosome 2BS with genetic distances of 0.3, 7.9, 12.3, and 21.2 cM, respectively. Crosses of CN19 with wheat lines carrying other genes on chromosome 2B showed that all were located at different loci. YrCN19 is thus different from the other reported Yr genes in chromosomal location and resistance response and was therefore named Yr41. Prospects and strategies of using Yr41 and other Yr genes in wheat improvement for stripe rust resistance are discussed.
