Abstract
Multiple myeloma (MM) is the second most common malignant haematological disease with a poor prognosis. The limit therapeutic progress has been made in MM patients with cancer relapse, necessitating deeper research into the molecular mechanisms underlying its occurrence and development. A genome-wide CRISPR-Cas9 loss-of-function screening was utilized to identify potential therapeutic targets in our research. We revealed that COQ2 plays a crucial role in regulating MM cell proliferation and lipid peroxidation (LPO). Knockout of COQ2 inhibited cell proliferation, induced cell cycle arrest and reduced tumour growth in vivo. Mechanistically, COQ2 promoted the activation of the MEK/ERK cascade, which in turn stabilized and activated MYC protein. Moreover, we found that COQ2-deficient MM cells increased sensitivity to the LPO activator, RSL3. Using an inhibitor targeting COQ2 by 4-CBA enhanced the sensitivity to RSL3 in primary CD138+ myeloma cells and in a xenograft mouse model. Nevertheless, co-treatment of 4-CBA and RSL3 induced cell death in bortezomib-resistant MM cells. Together, our findings suggest that COQ2 promotes cell proliferation and tumour growth through the activation of the MEK/ERK/MYC axis and targeting COQ2 could enhance the sensitivity to ferroptosis in MM cells, which may be a promising therapeutic strategy for the treatment of MM patients.

Abstract
Laboratory testing is a vital chain in the prevention and control of genital chlamydia trachomatis infection. The prevalence of genital chlamydia trachomatis infection is high, but the detection rate of the infection is low in men who have sex with men (MSM) in China. Self-sampling for genital chlamydia trachomatis detection by MSM is a new option to address this problem, which would play a significant role in expanding genital chlamydia trachomatis infection screening in this population. This paper summarizes the progress in research of self-sampling for the detection of genital chlamydia trachomatis and the related factors in MSM both at home and abroad to provide reference for the promotion of self-sampling for the detection of genital chlamydia trachomatis in this population.

Abstract
Objective: Gastric adenocarcinoma of the fundic gland type (GA-FG) is rare and often occurs in patients who are not infected with Helicobacter pylori. The current study analyzed and summarized the clinical, endoscopic, and pathological features of GA-FG, in an effort to improve its diagnosis. Methods: Patients who were diagnosed with GA-FG and treated with endoscopic submucosal dissection (ESD) resection at the Department of Gastroenterology, First Affiliated Hospital of Zhejiang Chinese Medical University from January 1st 2020 to October 1st 2022 were included in the study. Their clinical manifestations, endoscopic features, pathological immunohistochemistry, and other characteristics were analyzed. Results: A total of 14 patients with GA-FG were included in the study, 5 males and 9 females, with a mean age of 59 years. Most had no substantial clinical manifestations. Twelve patients were H. pylori-negative, all patients underwent ESD resection, and all patients survived during the follow-up period of 13±9 months. Eleven patients had postoperative endoscopic follow-up records, and no recurrence was detected. Fifteen lesions were detected (2 were present in 1 patient). Twelve were located in the upper 1/3 of the stomach, 10 were ≤ 1 cm in diameter, 12 had a morphology of type 0-Ⅱa, 8 had visible discoloration changes, and 12 had visible vasodilation on the surface. Magnified endoscopy and narrow-band imaging indicated that 12 of the lesions had enlarged marginal crypt epithelium, without any obvious microvascular pattern abnormalities and no obvious borderline. After resection the pathological specimens were all without vascular infiltration, and there was no atrophy of the mucosa at the edge of the lesion. In immunohistochemistry analyses MUC-2 was negative in all cases. MUC5AC was negative in 11 cases, MUC-6 was positive in all cases, and Ki-67 was ≤ 5% in 12 cases. Conclusions: GA-FG is a newly identified type of gastric cancer with low malignancy and a good prognosis. Characteristic discoloration and surface dilated vessels are often evident endoscopically. Enlarged marginal crypt epithelium and no visible boundary lines are often apparent in magnification endoscopy and narrow band imaging.

Abstract
Objective: To investigate the effect of embryo quality at different developmental stages on the secondary sex ratio (SSR) of single live birth neonates. Methods: Data for patients with singleton live births after embryo transferred between January 2016 and January 2022 were retrospectively analyzed. The effect of embryo quality at different development stages on the SSR of 11 713 singleton live births were investigated. The association of SSR and embryo quality at different development stages was examined in univariate analysis and in a multivariate logistic regression model, after adjustment for confounders, using two models (Ⅰ and Ⅱ). Results: The age of both male and female, body mass index of both male and female, basal follicle stimulating hormone and estradiol, smoking of male, methods of insemination, methods of sperm extraction, types of transfer cycle and the number of embryo transferred were not related with SSR (all P>0.05). After adjustment for confounders, the probability of a male live birth was higher after transfer of good-quality blastula than after transfer of poorer-quality blastula (model Ⅰ: aOR=0.73, 95%CI: 0.65-0.82, P<0.001; model Ⅱ: aOR=0.73, 95%CI: 0.65-0.82, P<0.001). The quality of cleavage stage embryo was not associated with SSR (model Ⅰ: aOR=0.99, 95%CI: 0.87-1.13, P=0.937; model Ⅱ: aOR=0.99, 95%CI: 0.87-1.13, P=0.899). Conclusions: The SSR of singleton live births after embryo transfer is not correlated with the quality of cleavage stage embryo, but is correlated with the quality of blastula. Good-quality blastula transfer is more likely to result in a male live birth.

Abstract
Objective: To observe the status of patient-reported outcomes (PROs) and their correlation with the number of hospitalizations within 1 year in patients with atrial fibrillation(AF). Methods: This study is a prospective investigation. Patients with non-valvular atrial fibrillation treated in the Department of Cardiology of the Third People's Hospital of Yancheng from May 2020 to April 2021 were selected. General information and AF6 questionnaire were used to define PROs. The number of hospitalizations within 1 year after discharge was obtained. Spearman correlation analysis was used to analyze the correlation between PROs and the New York Heart Association (NYHA) classification. The logistic regression model was used to analyze the number of hospitalizations in AF patients within 1 year. Results: A total of 197 patients were enrolled, the mean age was (74.1±9.0) years, 106 (53.8%) patients were female. The mean AF6 score was (24.3±8.3). The proportion of patients with 6 entries≥1 point exceeded 50%. There was a positive correlation between NYHA classification and PROs (r=0.360, P<0.001). Logistic regression analysis showed that the older age (OR=1.058, P=0.004) and the AF6 scores≥24(OR=4.082, P<0.001) were the risk factors of rehospitalization within 1 year for AF patients. Conclusions: The PROs of AF patients are at the medium level and poor levels of PROs are associated with increased risk of rehospitalization within 1 year.

Abstract
Objective: To compare the volumetric changes of cervical disc herniation (CDH) after cervical microendoscopic laminoplasty(CMEL),expansive open-door laminoplasty (EOLP) and conservative treatment. Methods: A retrospective study was conducted involving 101 patients with cervical spondylotic myelopathy(CSM),at the Department of Orthopaedic Surgery,the First Affiliated Hospital of Zhengzhou University from April 2012 to April 2021. The patients included 52 males and 49 females with an age of (54.7±11.8) years(range:25 to 86 years). Among them, 35 patients accepted CMEL treatment,33 patients accepted EOLP treatment,while 33 patients accepted conservative treatment. Volume data of CDH were measured by three-dimensional analysis of the initial and follow-up MRI images. The absorption rate and reprotrusion rate of CDH were calculated. The happening of resorption or reprotrusion was defined when the ratio was greater than 5%. The clinical outcomes and quality of life were evaluated by the Japanese Orthopaedic Association (JOA) score and the neck disability index (NDI).Quantitative data was analyzed by one-way ANOVA with post LSD-t test (multiple comparison) or Kruskal-Wallis test. Categorical data was analyzed by χ2 test. Results: The follow-up time of the CMEL group,EOLP group and the conservative treatment group were (27.6±18.8)months,(21.6±6.9)months and(24.9±16.3)months respectively with no significant difference(P>0.05). Changes of CDH volume in patients:(1) There were 96 CDH of 35 patients in the CMEL group,among which 78 showed absorption. The absorption frequency was 81.3%(78/96) and the absorption rate was ranged 5.9% to 90.9%;9 CDH showed reprotrusion,the reprotrusion frequency was 9.4% (9/96) and the reprotrusion rate was 5.9% to 13.3%;(2) There were 94 CDH of 33 patients in the EOLP group,of which 45 showed absorption. The absorption prevalence was 47.9% (45/94) and the absorption rate was 5.0% to 26.7%;20 CDH showed reprotruded,with the reprotrusion frequency of 21.3% (20/94) and the reprotrusion rate was 5.8% to 28.3%;(3) There were 102 CDH in 33 patients of the conservative group. Among them, 5 showed absorption. The absorption frequency was 4.9% (5/102),and the absorption rate was 7.2% to 14.3%;58 CDH showed reprotruded with the re-protrusion ratio of 56.9% (58/102) and the re-protrusion rate was 5.4% to 174.1%. The absorption ratio and reprotrusion ratio of the CMEL group were statistically different from EOLP group or the conservative group (P<0.01).The absorption ratio and reprotrusion ratio of the EOLP group was different from conservative group (all P<0.01). In terms of clinical outcomes, the excellent/good rate of the JOA score and NDI scores in the CMEL group were different from that of conservative group (all P<0.01) but not from that of the EOLP group(P>0.05). Conclusions: CMEL is an effective method for the treatment of CSM,making CDH easier to resorption compared to the EOLP or conservative treatment,thus making a better decompression effect on the nerves. This study enlightened on a new strategy for the clinical treatment of CSM.

Abstract
Objective: To investigate the effect of laparoscopic ovarian cystectomy on anti-Mullerian hormone (AMH) level, ovarian response to gonadotropin stimulation and pregnancy rate for in vitro fertilization (IVF) patients with benign ovarian cysts. Methods: Patients with benign ovarian cysts who were admitted for cystectomy and had undergone IVF treatment were enrolled in the study. There were 373 participants with ovarian cysts underwent laparoscopic ovarian cystectomy in the experimental group. According to duration of post-surgery, there were four sub-groups: 1 year post-surgery (1Y POST), 2 years post-surgery (2Y POST), 4 years post-surgery (4Y POST) and ≥5 years post-surgery (≥5Y POST) in the experimental group. According to histopathologic types of ovarian cysts, there were two sub-groups: ovarian endometriotic cysts and ovarian non-endometriotic cysts. Two hundreds and three patients with no history of ovarian cysts and ovarian surgery were in the control group. The level of AMH and basic concentrations of follicle stimulating hormone (FSH), luteinizing hormone (LH), progesterone (P), estradiol (E2) were measured. Antral follicle counts (AFC) were calculated. There were other study variables: total dose of gonadotropins, duration of ovarian stimulation, the number of oocyte retrieved, the number of embryo obtained, blastocyst transfer rate and pregnancy rate. Results: The control group was matched as closely as possible to the experimental group, including age, body mass index and menstrual cycle (all P>0.05). Compared to the women in control group, the women in ovarian endometriotic cystectomy sub-group had significantly higher levels of basal FSH and basal P, lower level of AMH (all P<0.05); the women in ovarian endometriotic cysts sub-group had significantly higher dose of gonadotropins (all P<0.05); the women in ovarian endometriotic cysts ≥5Y POST sub-group had significantly lower number of oocyte retrieved, lower number of embryo obtained, lower blastocyst transfer rate, and lower pregnancy rate (all P<0.05). Compared to the women in control group, the women in ovarian non-endometriotic cysts sub-group had a significantly higher level of basal FSH and basal P (all P<0.05). The women in ovarian non-endometriotic cysts sub-group had lower level of AMH, higher dose of gonadotropins, lower number of oocyte retrieved, lower number of embryo obtained, lower rate of blastocyst transfer and lower rate of pregnancy than the control group but there were no statistically significant differences among them (all P>0.05). The women with unilateral ovarian endometriotic cysts had significantly lower number of oocyte retrieved on the side of surgery than another side (P<0.05). Conclusions: In short term laparoscopic ovarian cystectomy has no significant effect on ovarian reserve. But with long-term follow-up ovarian reserve, ovarian response to gonadotropin stimulation and pregnancy rate are decreased. The effect of laparoscopic ovarian cystectomy in benign cysts on ovarian is associated with whether or not it is the surgical side.

Abstract
Objective: To explore the clinical outcomes of top-quality blastocysts transfer developed from cleavage embryos with different grading and determine whether the cleavage stage embryo morphology grading should be taken into consideration when transferring the embryo at the blastocyst stage. Methods: A number of 3 059 cycles were included with single top-quality blastocyst transfer dating from January 2017 to May 2021 in Henan Provincial People's Hospital. According to the number of cleavage sphere and degree of fragmentation, all cleavage stage embryos were divided into three groups: top D3 embryo (8 cells, ≤5% fragments)-TB group, suboptimal D3 embryo (8 cells, 5%<fragments≤10%; 7 cells or 9 cells, ≤10%)-TB group, and normal D3 embryo-TB group. Univariate analysis, multivariate logistic regression analysis and threshold effect analysis were performed on the data. Results: The clinical pregnancy rates of top D3 embryo-TB group(1 326 cycles), suboptimal D3 embryo-TB group (830 cycles) and normal D3 embryo-TB group (903 cycles) were 69.53%, 70.12% and 66.67%, respectively (P>0.05); and the early abortion rate were 10.74%, 12.54% and 12.62%, respectively (P>0.05). After adjusting for confounders, logistic regression showed that no significant associations were found between cleavage stage embryo morphology grading and clinical pregnancy rate (suboptimal D3 embryo-TB group: OR=1.02, 95%CI: 0.76-1.38, P=0.879; normal D3 embryo-TB group: OR=0.84, 95%CI: 0.61-1.14, P=0.262) and early abortion rate (suboptimal D3 embryo-TB group: OR=1.18, 95%CI: 0.77-1.82, P=0.445; normal D3 embryo-TB group: OR=1.26, 95%CI: 0.81-1.98, P=0.309). The results of threshold effect analysis showed that when a single top-quality blastocysts was transferred, the effect of age on the clinical pregnancy rate showed a curve relationship, when the age was≥33 years old, the clinical pregnancy rate decreased significantly with age increased (OR=0.89, 95%CI: 0.83-0.95, P=0.007); and there was no significant change in early abortion rate (OR=1.01, 95%CI: 0.97-1.06, P=0.628). Conclusions: Cleavage stage embryo grading is not found to correlate with clinical outcomes in single top-quality blastcyst tranfer. Therefore, when considering blastocyst transfer, its morphology at blastocyst stage is more relevant. The effect of age on pregnancy outcomes of single blastocyst transfer should be considered.

Abstract
Objective: To estimate the safety of myomectomy in twin pregnant women with intramural myomas during cesarean section. Methods: The clinical data of 145 cases of twin pregnancies with intramural myomas who were delivered by cesarean section in Beijing Obstetrics and Gynecology Hospital, Capital Medical University from June 2013 to December 2021 were collected. Maternal demographics, fibroids' characteristics, maternal and fetal outcomes were compared between groups of cesarean section with myomectomy (myomectomy group, 49 cases) and cesarean section only (non-myomectomy group, 96 cases). Results: Compared with non-myomectomy group, myomectomy group had significantly prolonged operative time [50.0 minutes (37.5-57.5 minutes) vs 40.0 minutes (35.0-50.0 minutes), respectively; P=0.007] and significantly longer postoperative hospital stay [4.0 days (3.0-4.0 days) vs 3.0 days (3.0-4.0 days), respectively; P=0.047). Other maternal and fetal outcomes such as estimated blood loss, hemoglobin difference, postpartum hemorrhage, blood transfusion, B-Lynch structure, uterine artery ligation, postoperative fever and neonatal Apgar score showed no significant differences (all P>0.05). For intramural myomas <5 cm, there were no significant differences in maternal and fetal outcomes between myomectomy group and non-myomectomy group (all P>0.05). For intramural myomas ≥5 cm, operative time [55.0 minutes (40.0-60.0 minutes) vs 42.5 minutes (40.0-50.0 minutes), respectively; P=0.019] was significantly prolonged, postoperative hospital stay [4.0 days (4.0-5.0 days) vs 4.0 days (3.0-4.0 days), respectively; P=0.048] was significantly longer in myomectomy group than non-myomectomy group, but there were no significant differences in other maternal and fetal outcomes (all P>0.05). Conclusion: For twin pregnancies with intramural myomas, it is safe and feasible to remove intramural myomas during cesarean section by experienced obstetricians.

Abstract
Objective: To investigate the application and clinical efficacy of ultrasound debridement method in residual burn wounds. Methods: A retrospective cohort study was conducted. From August 2017 to August 2021, 64 patients with residual burn wounds who met the inclusion criteria were admitted to the 980th Hospital of the Joint Logistic Support Force of PLA. According to the debridement method adopted for the residual wounds, the patients were divided into ultrasound debridement group (34 cases, 22 males and 12 females, aged (31±13) years) and traditional debridement group (30 cases, 19 males and 11 females, aged (32±13) years). After the corresponding debridement, the wounds of patients in the two groups were selected for stamp skin grafting or large skin grafting according to the wound site and skin donor status. For unhealed wounds after stage Ⅰ surgery, secondary debridement and skin grafting were be performed, with the wound debridement methods in the 2 groups being the same as those of stage Ⅰ, respectively. On postoperative day 3, drug-sensitive test was used to detect the bacteria in the wound and the positive rate of bacteria was calculate. On postoperative day 7, the survival rate of skin slices in wound and the incidence of subcutaneous hematoma were calculated. At discharge, wound healing time and debridement times of patients were counted, and the secondary debridement rate was calculated. Data were statistically analyzed with independent sample t test or chi-square test. Results: On postoperative day 3, the wounds in ultrasound debridement group were infected with Staphylococcus aureus in 2 cases and Pseudomonas aeruginosa in 2 cases, and the wounds in traditional debridement group were infected with Staphylococcus aureus in 5 cases, Pseudomonas aeruginosa in 3 cases, Acinetobacter baumannii in 1 cases, Klebsiella pneumoniae in 1 cases, and Enterobacter cloacae in 1 cases. The positive rate of bacteria of wound in ultrasound debridement group was significantly lower than that in traditional debridement group (χ2=5.51, P<0.05). On postoperative day 7, the survival rate of skin grafts in ultrasound debridement group was (92±5) %, which was significantly higher than (84±10) % in traditional debridement group (χ2=6.78, P<0.01); the incidence of subcutaneous hematoma in ultrasound debridement group was 17.6% (6/34), which was significantly lower than 40.0%( 12/30) in traditional debridement group, χ2=3.94, P<0.05. At discharge, the wound healing time in ultrasound debridement group was (11.0±2.0) d, which was significantly shorter than (13.0±3.1) d in traditional debridement group (t=3.81, P<0.01); the secondary debridement rate of wounds in ultrasound debridement group was 2.9% (1/34), which was significantly lower than 20.0% (6/30) in traditional debridement group (χ2=4.76, P<0.05). Conclusions: Ultrasound debridement method can significantly reduce the bacterial load of residual burn wounds, reduce postoperative hematoma formation, and promote the survival of skin grafts to shorten the course of disease of patients.

Abstract
Objective: To explore the effectiveness, safety and cost between urinary follicle stimulating hormone (uFSH) and recombinant follicle stimulating hormone (rFSH) in controlled ovarian stimulation (COS) in China. Methods: Data were collected from 16 reproductive centers in China covering oocytes collection time from May 1, 2015 to June 30, 2018. Eligible patients were over 18 years old, adopting COS with uFSH (uFSH group) or rFSH (rFSH group) as start gonadotropins (Gn), and using in vitro fertilization (IVF) and (or) intracytoplasmic sperm injection for fertilisation, excluding frozen embryo recovery cycle. Generalised estimating equation was used to address the violation of independency assumption between cycles due to multiple IVF cycles for one person and clustering nature of cycles carried out within one center. Controlling variables included age, body mass index, anti-Müllerian hormone level, cause of infertility, ovulation protocol, type of fertilisation, number of embryos transferred, number of days of Gn use. Results: Totally 102 061 cycles met eligibility criteria and were included in the analyses. In terms of effectiveness, after controlling relevant unbalanced baseline characteristics, compared with rFSH group, the high oocyte retrieval (>15 oocytes was considered high retrieval) rate of uFSH group significantly decreased in gonadotropin-releasing hormone agonist protocol (OR=0.642, P<0.01) and in gonadotropin-releasing hormone antagonist protocol (OR=0.556, P=0.001), but the clinical pregnancy rate per transfer cycle and the live birth rate per transfer cycle significantly increased (OR=1.179, OR=1.169, both P<0.01) in both agonist and antagonist protocols. For safety, multiple analysis result demonstrated that in the agonist protocol, compared with rFSH group, the incidence of moderate to severe ovarian hyperstimulation syndrome of uFSH group significantly decreased (OR=0.644, P=0.002). The differences in ectopic pregnancy rate and multiple pregnancy rate between the uFSH and rFSH groups were not significant (P=0.890, P=0.470) in all patients. In terms of cost, compared with rFSH group, the uFSH group had lower total Gn costs for each patient (P<0.01). Conclusion: For patients who underwent COS, uFSH has better safety, and economic profiles over rFSH in China.

Abstract
Objective: To screen the differently expressed microRNAs (miRNAs) and to explore the effect and mechanism of microRNA-3907 (miR-3907) in meibomian gland carcinoma (MGC). Methods: Experimental research. MGC tissues and para-carcinoma tissues of patients diagnosed with MGC by histopathology were collected from July 2011 to January 2019 in Tianjin Medical University Eye Hospital. The miRNA microarray analysis of MGC and para-carcinoma tissue samples from 5 patients was performed. miR-3907 with a significant up-regulation was selected as a research object. Bioinformatics predicted and dual-luciferase gene reporter assay verified miR-3907 target genes. The protein expression levels of target genes in 18 MGC tissues and 6 para-carcinoma tissue samples were determined by immunohistochemical staining. miR-3907 over-expression, miR-3907 knock-down, target gene knock-down and miR-3907 knock-down with target gene knock-down were respectively performed in MGC cell. The mRNA and protein expressions were validated by real-time PCR and Western blotting after transfection. The cell proliferation and migration ability was detected by cell counting kit-8 and scratch experiment after transfection. The main statistical methods were Fisher's exact test, independent sample t test, two-factor repeated measure analysis of variance. Results: There were 22 differently up-regulated miRNAs and 5 differently down-regulated miRNAs in MGC tissues, of which miR-3907 was significantly up-regulated. Thrombospondin-1 (THBS1) was a target gene of miR-3907 according to bioinformatics and dual-luciferase gene reporter assay. The positive expression rate of THBS1 protein in para-carcinoma tissues (6/6) was significantly higher than that in MGC tissues (5/18), and the difference was statistically significant (P=0.003). Compared with the negative control group, the proliferation ability of the miR-3907 over-expression group was increased at 48 h and 72 h (F=3.70, 2.65; both P<0.01), and the migration rate at 24 h was significantly higher (54.6%±3.4% vs. 34.2%±0.6%; t=8.34, P<0.01). Compared with the negative control group, the proliferation ability of the miR-3907 knock-down group was decreased at 24 h, 48 h and 72 h (F=3.10, 2.17, 3.09; all P<0.05), and the migration rate at 24 h was significantly lower (40.8%±2.8% vs. 69.7%±2.7%; t=10.42, P<0.01). Compared with the negative control group, the THBS1 knock-down group promoted cell proliferation at 24 h, 48 h and 72 h (F=3.84, 3.79, 2.24; all P<0.05), and the migration rate at 24 h was significantly increased (82.5%±1.9% vs. 37.6%±5.1%; t=11.74, P<0.01). Compared with the control group, the miR-3907 knock-down with THBS1 knock-down group increased proliferation at 24 h and 48 h (F=3.97, 3.31; both P<0.05), and the migration healing rate at 24 h was significantly increased (56.9%±2.2% vs. 41.9%±4.3%; t=3.53, P<0.05). Conclusions: There are differently expressed miRNAs between MGC and para-carcinoma tissues, which may be related to the occurrence and development of MGC. miR-3907 in MGC tissues has a significant difference from that in para-carcinoma tissues. Moreover, miR-3907 can play a role in promoting proliferation and migration of MGC by inhibiting the expression of THBS1.

Abstract
Objective: To explore the related factors of poor ovarian response (POR) in patients receiving controlled ovarian stimulation (COS) and to establish the nomogram for predicting POR in patients who received in vitro fertilization or intracytoplasmic sperm injection (IVF/ICSI). Methods: In this retrospective research, clinical data of 17 164 cycles of patients who received IVF/ICSI treatment at Henan Provincial People's Hospital from September 1st, 2016 to September 1st, 2020 were analyzed. Independent correlative factors affecting the occurrence of POR were screened by logistic regression, which were the model enrollment variables in the prediction model. Totally 13 266 cycles with well-record of enrollment variables were screened, and these data were randomly divided into model group (9 896 patients) and validation group (3 370 patients) according to 3∶1. The nomogram was established according to the regression coefficient of the relevant variables. The prediction accuracy of the nomogram was evaluated by calculating area under the receiver operating characteristic curve (AUC). Results: Multivariate logistic regression analysis showed age, infertility type, body mass index, anti-Müllerian hormone, basal follicle stimulating hormone, basal estrogen, antral follicle number, previous times of POR, history of ovarian surgery, ovulation stimulation protocol and average amount of gonadotropin were independent correlative factors affecting the occurrence of POR (all P<0.05). In the model group, according to the above factors, the prediction model and nomogram of POR risk were constructed and the validation group verified the model. The AUC of the model group was 0.893 (95%CI: 0.885-0.900), and the AUC of the validation group was 0.890 (95%CI: 0.878-0.903). Conclusion: The influencing factors of POR after COS in patients treated by IVF/ICSI are screened, and the nomogram for predicting POR established in this study is proved to be effective, simple, intuitive and clear in predicting the occurrence of POR.

Abstract
OBJECTIVE To analyze the polymorphism of Plasmodium lactate dehydrogenase (pLDH) gene and predict B-cell epitopes in pLDH peptides in four species of human malaria parasites. METHODS The blood samples and epidemiological characteristics were collected from malaria cases in Yunnan Province registered in the National Notifiable Disease Report System. The pLDH genes of four human Plasmodium species were amplified using nested PCR assay and sequenced. The polymorphisms of pLDH genes was analyzed using the software MEGA version 7.0.26 and DnaSP version 5.10, and the B-cell epitopes were predicted in pLDH peptides using the Immune Epitope Database (IEDB). RESULTS The sequences of P. vivax LDH (PvLDH), P. falciparum LDH (PfLDH), P. ovale LDH (PoLDH) and P. malariae LDH (PmLDH) genes were obtained from 153, 29, 17 and 11 blood samples from patients with P. vivax, P. falciparum, P. ovale and P. malariae malaria, respectively, which included 15, 2, 4 and 2 haplotypes and had a nucleotide diversity (π) of 0.104. A high level of intra-species differentiation was seen in the PoLDH gene (π = 0.012), and the π values were all < 0.001 for PvLDH, PfLDH and PmLDH genes. Active regions of B-cell antigen were predicted in the pLDH peptide chain of four human malaria parasites, of 4 to 5 in each chain, and the activity score was approximately 0.430. Among these peptide chains, the "86-PGKSDKEWNRD-96" short-peptide was a B-cell epitope shared by all four species of human malaria parasites, and the "266-GQYGHS (T)-271" short-peptide was present in PvLDH and PoLDH peptide chains, while "212-EEVEGIFDR-220" was only found in the PvLDH peptide chain, and "208-LISDAE-213" was only seen in the PfLDH peptide chain. CONCLUSIONS The PoLDH gene polymorphism may be derived from the weak negative purification selection, while PvLDH, PfLDH and PmLDH genes may maintain a relatively conservative state. There may be two B-cell epitopes "212-EEVEGIFDR-220" and "208-LISDAE-213" in the proximal region of the C terminal in the pLDH peptide chain, which is feasible to differentiate between P. vivax and P. falciparum infections.

Abstract
Objective: To evaluate the prognostic effects of two comprehensive geriatric assessment (CGA) methods in elderly patients with acute myeloid leukemia (AML). Methods: Ninety-seven patients with newly diagnosed AML at Beijing Hospital from August 2008 to December 2019 were included (≥60 years old). All patients were evaluated by two methods of CGA. One was IACA index proposed by Beijing Hospital, including instrumental activities of daily living (IADL), age, Charlson comorbidity index (CCI), albumin; the other was proposed by Italian FIL study group (FIL-CGA), including activities of daily living (ADL), IADL, age, and modified cumulative illness rating score for geriatrics (MCIRS-G). Results: Among 97 patients, 54 patients received standard chemotherapy, 16 with decitabine, 2 with targeted therapy and 25 with the best supportive therapy. The overall response rate (ORR) in 72 treated patients were 67.7%, 33.3% and 0 respectively in fit, unfit and frail groups according to IACA index (P=0.001). Based on FIL-CGA, the ORRs of fit, unfit and frail groups were 52.5%, 41.7% and 35.0% respectively (P=0.418). The 1-year OS rates of fit, unfit and frail groups regarding IACA method were 78.7%, 27.7% and 0 respectively (P<0.01). The 1-year OS rates of fit, unfit and frail groups regarding FIL-CGA method were 67.8%, 28.2% and 13.9% respectively (P<0.01), while no significant difference was seen between unfit group and frail group (P=0.111). The early death rates of fit, unfit and frail groups by IACA were 0, 6.0% and 28.6% respectively (P=0.006), while those by FIL-CGA were 2.3%, 5.9%, 13.9% respectively (P=0.123). Conclusion: Compared with FIL-CGA method, IACA predicts more effectively the treatment response, survival and early mortality in elderly patients with AML.

Abstract
Through literature analysis of Pheretima and its origin-related earthworm,this study summarized the progress on Pheretima in textual criticism of origin,origin identification,effective components,detection of harmful components,and pharmacological effects,which can lay a basis for further research on Pheretima. Through literature research,the authors found that Pheretima was first recorded in Secret Formulary for Traumatology and Fracture Taught by Immortal written by LIN Daoren in Tang Dynasty rather than the Taiping Holy Prescriptions for Universal Relief in Song Dynasty. The latest techniques for origin identification include microscopic trait identification,DNA barcoding,and HPLC. The main effective components of Pheretima are proteins,polypeptides,enzymes,nucleotides,amino acids,and trace elements. According to recent studies,Pheretima has anti-pulmonary and anti-renal interstitial fibrosis,respiratory syncytial virus-inhibiting,human hypertrophic scar fibroblast proliferation-suppressing,and mouse embryonic fibroblast proliferation-promoting effects. Moreover,Pheretima can prevent colitis-induced colon cancer by inhibiting the activation of COX-2/PGE2/β-catenin signaling pathway. METHODS:: for detecting the harmful components and their residues( organic pollutant polychlorinated biphenyl,heavy metals) and bacteria in Pheretima,have been established. Pheretima,mainly derived from wild earthworms,has remarkable clinical efficacy. However,the wild resource is in short supply and artificial culture is expected to be a promising solution.

Abstract
Objective: To analyze the protein expression differences of lacrimal gland adenoid cystic carcinoma (LACC) with high-grade transformation (HGT). Methods: Experimental study. A total of 8 paraffin tissue samples were collected in Tianjin Medical University Eye Hospital from December 2012 to January 2019. According to pathological examination, the samples were divided into the LACC group and the LACC-HGT group, with 4 cases in each group. The LACC group included 2 male samples and 2 female samples, with an average age of 53 years. The LACC-HGT group included 2 male samples and 2 female samples, with an average age of 44 years. Primary cells were cultured from fresh tumor tissue. Isobaric tags for relative and absolute quantification techniques were used to screen the differentially expressed proteins between the two groups, and bioinformatics analysis was conducted for the differentially expressed proteins. Microarray was used to screen differentially expressed mRNAs between LACC and LACC-HGT primary cells. The mass spectrum data were intersected with mRNA microarray data, and quantitative real-time (qRT) PCR was performed to verify the results. Proteomics and microarray data were compared using the independent sample t test. The qRT-PCR data were compared pairwise by one-way analysis of variance. Results: A total of 105 HGT-related differential proteins were detected in this study, including 50 up-regulated proteins and 55 down-regulated proteins. The significantly up-regulated proteins included hemoglobin subunit beta, hemoglobin subunit alpha 1, and collagen type Ⅵ alpha 2 chain; the significantly down-regulated proteins included Cereblon, adenosylhomocysteinase like 2, and ribosomal protein L39 pseudogene 5. Gene ontology analysis results showed that the LACC-HGT differential proteins were mainly located in the cytoplasm, vesicle cavity, and extracellular matrix, had organic acid binding and molecular carrier activity, and participated in the regulation of extracellular matrix composition, immunity, inflammation, apoptosis, and other biological processes. Pathway analysis showed that the LACC-HGT differential proteins were mainly involved in signal pathways such as mitogen-activated protein kinase signal pathway and extracellular matrix proteoglycans and glycan metabolism signal pathway. Protein complex prediction analysis screened out 4 up-regulated protein complexes and 1 down-regulated protein complex. There were 15 LACC-HGT differential proteins that overlapped with mRNA chip differential genes, of which 6 were tumor-related proteins including collagen type XIV alpha 1 chain (COL14A1), EMAP like 4 (EML4), inter-alpha-trypsin inhibitor heavy chain 4 (ITIH4), NDRG family member 2 (NDRG2), osteoglycin (OGN) an Ras homolog family member C (RhoC). The main function was the movement and migration of tumor cells. The qRT-PCR results showed that the relative expression levels of COL14A1, EML4, ITIH4, NDRG2, OGN, and RhoC in primary LACC-1, LACC-2, LACC-HGT-1, and LACC-HGT-2 cells were significantly different (F=1 675.98, 38.53, 27.37, 16.47, 13.38, 25.22, all P<0.01). For example, the relative expression of COL14A1 in primary LACC-HGT-1 (16.09±0.51) and LACC-HGT-2 (9.96±0.34) cells was significantly higher than that in primary LACC-1 (1.00±0.13) and LACC-2 (0.67±0.08) cells (all P<0.05). Conclusion: There are differentially expressed proteins between LACC-HGT and LACC, among which COL14A1, EML4, ITIH4, NDRG2, OGN, and RhoC may play an important role in LACC-HGT and can be used as potential targets of LACC-HGT in further study.

Abstract
Objective: To explore the consistency of peripheral whole blood and venous serum procalcitonin (PCT) levels, and the value of peripheral whole blood PCT in evaluating pediatric bacterial infection. Methods: This multicenter cross-sectional parallel control study was conducted in 11 children's hospital. All the 1 898 patients older than 28 days admitted to these hospitals from March 2018 to February 2019 had their peripheral whole blood and venous serum PCT detected simultaneously with unified equipment, reagent and method. According to the venous serum PCT level, the patients were stratified to subgroups. Analysis of variance and chi-square test were used to compare the demographic characteristics among groups. And the correlation between the peripheral blood and venous serum PCT level was investigated by quantitative Pearson correlation analysis.The PCT resultes were also converted into ranked data to further test the consistency between the two sampling methods by Spearman's rank correlation test. Furthermore, the ranked data were converted into binary data to evaluate the consistency and investigate the best cut-off of peripheral blood PCT level in predicting bacterial infection. Results: A total of 1 898 valid samples were included (1 098 males, 800 females),age 27.4(12.2,56.7) months. There was a good correlation between PCT values of peripheral whole blood and venous serum (r=0.97, P<0.01). The linear regression equation was PCTvenous serum=0.135+0.929×PCTperipheral whole blood. However, when stratified to 5 levels, PCT results showed diverse and unsatisfied consistency between the two sampling methods (r=0.51-0.92, all P<0.01). But after PCT was converted to ordinal categorical variables, the stratified analysis showed that the coincidence rate of the measured values by the two sampling methods in each boundary area was 84.9%-97.1%. The dichotomous variables also showed a good consistency (coincidence rate 96.8%-99.3%, Youden index 0.82-0.89). According to the severity of disease, the serum PCT value was classified into 4 intervals(<0.5、0.5-<2.0、2.0-<10.0、≥10.0 μg/L), and the peripheral blood PCT value also showed a good predictive value (AUC value was 0.991 2-0.997 9). The optimal cut points of peripheral whole blood PCT value 0.5、1.0、2.0、10.0 μg/L corresponding to venous serum PCT values were 0.395, 0.595, 1.175 and 3.545 μg/L, respectively. Conclusions: There is a good correlation between peripheral whole blood PCT value and the venous serum PCT value, which means that the peripheral whole blood PCT could facilitate the identification of infection and clinical severity. Besides, the sampling of peripheral whole blood is simple and easy to repeat.

Abstract
Objective: To investigate the clinicopathological features and differential diagnosis of primary cutaneous nasal extranodal NK/T cell lymphoma (pcENKTCL-NT). Methods: Fifteen cases of pcENKTCL-NT were collected at the First Affiliated Hospital of Zhengzhou University from January 2016 to December 2019. The clinical characteristics, morphological features, immunophenotypes, and results of in situ hybridization and gene detection were analyzed. Results: Among the 15 patients, 7 were male and 8 were female, with a male to female ratio of 1.0∶1.1. Their ages ranged from 29 to 86 years, and the median age was 59.3 years. All patients were hospitalized for skin lesions, including skin ulcers, scattered patchy red papules, and local blisters. The skin lesion might be a hard nodular mass, and part of it was a confluent patchy erythema; it could be manifested as multiple scattered nodules of different sizes, and some lesions were like round ulceration. There were 8 cases of lower limbs, 4 cases of chest (1 case with upper limb lesions), 2 cases of trunk and 1 case of neck. Most of the patients were sensitive to GGDP regimen (cisplatin, dexamethasone, gemcitabine and pemostatin). Histologically, most lesions showed tumor cells invading the epidermis and skin appendages, dermal infiltration, diffuse distribution, vascular and peritubular destruction, and some subcutaneous adipose tissue involvement. Morphologically, most of the tumor cells were mixed with small-to medium-size lymphocytes, and some were large cells, mixed cells or small cells. Immunohistochemistry showed that CD3, CD3 ε and TIA-1 were expressed in all cases, but not CD20 and CD8. CD56 and granzyme B were expressed in most of the cases, and CD5 was not expressed. Ki-67 positive index was about 50%-90%. EBV in situ hybridization was positive in all cases. The clonal rearrangement of T cell receptor gene was found in some CD56 negative cases. The 15 patients were followed up for 5-45 months, and one of them was lost to follow-up. Five patients died within 5-13 months after the diagnosis, accounting for 35.7% (5/14) of the 14 patients. The average survival time of the deceased patients was 8.6 months. Conclusions: The incidence rate of pcENKTCL-NT is relatively low, but its biological behavior is aggressive and its prognosis is overall poor. Its skin lesions and histopathological features are relatively diverse. The diagnosis should be determined with using clinical data, histological morphology, immunophenotype and EB virus in situ hybridization. At the same time, attention should be paid to differential diagnosis from other cutaneous lymphoma with cytotoxic phenotype to avoid missed diagnosis and misdiagnosis.

Abstract
The trapped electron states on a pliable lattice have different localization and physical chemistry characteristics. Here, terahertz time-domain measurements suggest that the formation of vanadyl oxygen defect, in the presence of the surface potential traps and mobile charge carriers, leads to a transient charge distribution that forms terahertz radiating dipoles in V2O5. The emergence of radiating dipoles is evidenced by terahertz responses with a two-valley feature of the thermally reduced α-V2O5 (001) thin films in the temperature range of 300-700 K. The two photoconductance valleys on a several millielectron volts interval are related to two emergent split-off traps, which originate from the VO6 octahedra distortion upon the vanadyl oxygen desorption on the surface. The pliable surface lattices plays a decisive role. So long as the α-V2O5 (001) thin films are covered by a 30 nm-thick Al2O3 capping layer, the distinct two-valley feature disappears completely in the full temperature range. The terahertz radiating dipoles with a fine energy structure is potentially a new measure for charge dynamics on the α-V2O5 (001) surface.

Abstract
Objective: To explore and compare the preventive effect of using letrozole and gonadotropin-releasing hormone (GnRH) antagonist during luteal phase of patients at high risk for ovarian hyperstimulation syndrome (OHSS). Methods: A total of 99 infertile women undergoing in vitro fertilization and embryo transfer or intracytoplasmic sperm injection with high risk for OHSS were enrolled in this randomized controlled trial.The letrozole group (n=51) received letrozole of 7.5 mg daily for 3 days;the GnRH antagonist group (n=48) were given cetrorelix of 0.25 mg subcutaneously daily for 3 days. Both groups received support therapy combined with embryo cryopreservation. The incidence of OHSS was surveyed. And the serum concentration of estradiol, LH and progesterone on days 3, 5 and 8 after oocytes retrieval were measured. Results: There were no statistical differences in terms of baseline characteristics of patients and outcomes of controlled ovarian hyperstimulation between the two groups.The incidence of moderate and severe OHSS was found no significantly difference between letrozole group [11.8%(6/51)] and GnRH antagonist group [10.4%(5/48);P>0.05]. The estradiol concentration of the indicated days on days 3,5 and 8 after oocytes retrieval in letrozole group and GnRH antagonist group were (1 417±3 543) versus (15 210±9 921) pmol/L, (1 692±4 330) versus (18 680±11 567) pmol/L, (239±336) versus (3 582±5 427) pmol/L, respectively;compared with GnRH antagonist group, the estradiol level was significantly lower in the letrozole group (all P<0.01). The luteinizing hormone level in the letrozole group were (0.46±0.40), (0.56±0.55)and (0.67±0.58) U/L on days 3,5 and 8 after oocytes retrieval, which were significantly higher than those of GnRH antagonist group [(0.28±0.28), (0.30±0.19) and (0.45±0.37) U/L, respectively; all P<0.05]. There was no obvious differences on progesterone levels between letrozole group and GnRH antagonist group (all P>0.05),and on days 8 after oocytes retrieval,the level of progesterone in each group were significantly lower than those on day 3 and 5 after oocytes retrieval (P<0.05). Conclusion: Letrozole has the same efficiency as GnRH antagonist for the prevention of OHSS, faster and cheaper to use, but its efficacy seems not to be related to the suppression of steroidogenic during the luteal phase.

Abstract
OBJECTIVE The current difficulties in the treatment of tumor include repeated administration and high recurrence rate after tumor resection. In order to reduce the number of doses, avoid side effects of chemotherapeutic drugs, suppress tumor growth and delay tumor recurrence after surgery, a temperature-sensitive in situ gel with paclitaxel microspheres (PTX/M gel) was prepared. PTX/M gel was administered by intratumoral injection once a month. METHODS First of all, paclitaxel microspheres (PTX/M) were prepared by emulsion solvent evaporation method. A laser particle size distribution analyzer was used to investigate the size, distribution, specific surface area of microspheres. Paclitaxel content was determined by high performance liquid chromatography (HPLC). Then encapsulation efficiency of paclitaxel was calculated and in vitro release characteristics were studied. Secondly, PTX/M gel was prepared by cold dissolution method. The phase transition temperature, elastic modulus, dissolution curve, correlation between dissolution and release were measured. Finally, U87 MG and 4T1 subcutaneous tumor models were established respectively to study the efficacy of PTX/M gel in suppressing tumor growth and delaying tumor recurrence after surgery. RESULTS The median diameter of the selected PTX/M was (32.24±1.09) μm, the specific surface area was (206.61±10.23) m2/kg, the encapsulation efficiency was 85.29%±1.34%, and the cumulative release percentage of paclitaxel from PTX/M was 33.56%±3.33% in one month. Phase transition temperature of PTX/M gel was 33 °C. The elastic modulus of PTX/M gel at 25 °C and 37 °C were 4.2×103 Pa and 18×103 Pa, respectively. The gel could stay in the body for up to 48 hours. It could be seen from the results of animal experiments that were compared with the saline group and the Taxol group, and the tumor-bearing mice of the PTX/M gel group had the slowest tumor growth (P<0.05). Similarly, in the tumor recurrence experiments, the mice of PTX/M gel group had the latest tumor recurrence after surgery. CONCLUSION As a local sustained-release preparation, PTX/M gel can effectively suppress tumor growth and delay postoperative recurrence of tumors. It has potential advantages in tumor treatment.

Abstract
Objective: To explore the value of anti-Müllerian hormone (AMH) and age in predicting outcomes of patients undergoing in vitro fertilization and embryo transfer treatment. Methods: In this retrospective study, 6 328 Chinese patients who underwent the first in vitro fertilization or intracytoplasmic sperm injection and embryo transfer treatment in Henan Provincial People's Hospital between July 2016 and July 2018 were analyzed. All the patients were categorized into two groups according to pregnancy or not. Baseline data and outcomes of two groups were compared. The regression analysis was conducted to identify the independent factors of clinical pregnancy rates. Furthermore, correlation analysis was performed between AMH and other factors. Results: (1) The total clinical pregnancy rate was 56.86% (3 547/6 238). Age, AMH, basal FSH, antral follicle number (AFC), starting dose of gonadotropin (Gn), total doses of Gn, duration of Gn, number of oocytes, transferable cleavage embryos and transferred embryos were significantly different (all P<0.01). (2) Correlation analysis showed that AMH had significant passive correlation with age, basal FSH, starting dose of Gn and total doses of Gn (all P<0.01), while showed significant positive correlation with AFC, body mass index, duration of Gn, number of oocytes and transferable cleavage embryos (all P<0.01). Of all the factors, AMH had the strongest correlation with AFC (P<0.01). (3) Multivariate logistic regression analysis suggested that age was the independent influencing factor of clinical pregnancy rate (OR=0.938, 95%CI: 0.824-0.952, P<0.01), while AMH not (OR=1.004, 95%CI: 0.984-1.024, P=0.687). In the subgroups according to age, the advanced group (age>35 years old) had lower clinical pregnancy rate and higher cancellation rate for no available embryos. Conclusions: AMH has no predictive value of clinical pregnancy outcomes for patients with in vitro fertilization and embryo transfer treatment, while age has certain predictive value of pregnancy outcomes. AMH level may have indictive value for the evaluation of ovarian reserve.

Abstract
Objective: To validate comprehensive geriatric assessment (CGA) system in Chinese elderly diffuse large B cell lymphoma (DLBCL) patients. Methods: Patients ≥ 65 years of age who had been diagnosed with de novo DLBCL were screened for eligibility (n=99). CGA was performed during staging procedures through application of the following instruments: age, comorbidity score according to the Cumulative Illness Rating Score for Geriatrics(CIRS-G), activities of daily living (ADL), and instrumental activities of daily living (IADL). Results: All patients were classified as "ft" , "unfit" , and "frail" . Forty-nine (49.5%), 14 (14.1%), and 34 (36.4%) patients were categorized into the fit, unfit, and frail groups, respectively. The overall response rate was 91.8%, 64.3%, and 69.5% in fit, unfit, and frail group, respectively (χ(2)=9.311, P=0.007). Eleven (22.4%), 7 (50.0%), and 16(44.4%) patients showed disease relapse/progression in fit, unfit, and frail group, respectively (χ(2)=6.309, P=0.040). The 2-year probability of overall survival was 90.6%, 43.0%, and 58.5% in fit, unfit, and frail group, respectively (χ(2)=14.774, P=0.001). The 2-year probability of progression-free survival was 72.9%, 32.5%, and 37.3% in fit, unfit, and frail group, respectively (χ(2)=11.038, P=0.004). Conclusion: The CGA index can predict the clinical outcomes of elderly DLBCL patients in China.

Abstract
目的 研究血清游离轻链(sFLC)检测在原发性轻链型淀粉样变(pAL)中的诊断和预后价值。 方法 回顾性分析2009年1月至2015年6月确诊且有完整sFLC数据的126例pAL患者的临床资料,探讨sFLC的诊断价值,并采用Cox回归法分析sFLC差值(dFLC)的预后价值。 结果 126例患者中男女比例为1.57∶1,中位年龄为57 (37~81)岁,λ轻链型者80例(63.5%),肾脏受累者87例(69.0%),心脏受累者79例(62.7%)。126例患者的中位dFLC为99 (1~4 263)mg/L。血清蛋白电泳、血清免疫固定电泳、尿免疫固定电泳和sFLC比值异常法检测单克隆免疫球蛋白(M蛋白)的阳性检出率分别为34.9%(44/126)、63.5%(80/126)、77.0%(97/126)和81.0%(102/126)。联合上述四种方法可将M蛋白的检出率提高至98.4%(124/126)。中位随诊16个月后,37例患者死亡,所有患者的中位生存时间尚未达到。多因素分析发现dFLC ≥130 mg/L是影响pAL患者预后的独立危险因素(HR=3.272, 95% CI 1.384~7.739,P=0.007)。 结论 sFLC检测可显著提高pAL患者M蛋白的检出率;高水平dFLC是影响患者预后的独立危险因素。

Abstract
Objective: To measure the comprehensive geriatric assessment (CGA) in elder non-Hodgkin's Lymphoma (NHL) patients in a cross-sectional study; to compare the differences between Eastern Cooperative Oncology Group (ECOG)-performance status (PS) and CGA. Methods: CGA stratification included the following 3 instrument assessments: activity of daily living (ADL);instrumental activity of daily living (IADL);comorbidity score according to the modified cumulative illness rating score for geriatrics (MCIRS-G). According to CGA and age, NHL patients, aged ≥60 years, were classified as"fit","unfit"and"frail"groups. ECOG-PS was evaluated and compared with CGA. Results: According to CGA, 51.6% senior NHL patients (33 cases) were classified as"fit", 12.5%(8 cases) as"unfit"and 35.9%(23 cases) as"frail". Several comorbidities were observed in majority patients, such as cardiovascular disease, diabetes mellitus and hypertension. In the"younger aged"patients between 60 to 64ys, 25%(3/12) was considered as"frail". However, this proportion increased to 42.9%(6/14) in patients older than 80ys. Moreover, impaired CGA was observed in 38.9%(21/54) of ECOG-PS ≤1 patient. Conclusions: Impaired CGA is as common as approximately half in elderly NHL patients and more than one third even in ECOG-PS ≤1 patients. ECOG-PS may underestimate the impaired fitness function in elder NHL patients.

Abstract
OBJECTIVE MicroRNA-155 (miR-155) is significantly highly expressed in breast cancer, lung cancer, liver cancer and other malignant tumors. This study was to design and construct a radiolabeled probe targeting miR-155 for in vivo imaging in breast cancer. METHODS Anti-miR-155 oligonucleotide (AMO-155) was chemically synthesized with 2' OMe modification. Its 5' end was linked with acetyl amine group. After chelated with a bifunctional chelator NHS-MAG3, AMO-155 was radiolabeled with 99mTc using stannous chloride. The serum stability was evaluated at cellular level. In vivo imaging was performed in MCF-7 tumor bearing mice after the administration of 99mTc radiolabeled AMO-155 and scramble control probes, respectively. Furthermore, the blocked imaging of tumor bearing mice was obtained after the injection of unlabeled AMO-155 2 hours ahead. MCF-7 and MDA-MB-231 tumor bearing mice with different expression level of miR-155 were imaged, respectively. Quantitative real-time PCR (qRT-PCR) was used to identify the expression level of miR-155 in the bearing tumors. RESULTS 99mTc-AMO-155 was prepared with high radiolabeled efficiency (97%), radiochemical purity (greater than 98%), and radioactive specific activity (3.75 GBq/μg). 99mTc-AMO-155 was stable in fresh human serum for 12 hours. After the administration via tail vein, 99mTc-AMO-155 displayed significant accumulation in MCF-7 bearing tumors with high expression level of miR-155, whereas 99mTc-control showed little accumulation. After blocked with unlabeled AMO-155, the tumor could not be visualized clearly after the administration of 99mTc-AMO-155. Furthermore, 99mTc-AMO-155 could show the differential expression of miR-155 in vivo. MCF-7 tumor was shown with significantly higher radioactive accumulation than MDA-MB-231, based on its higher expression level of miR-155, which was verified by qRT-PCR. CONCLUSION 99mTc-labeled AMO-155 with chemical modification showed good serum stability and in vivo tumor targeting ability. This study provides a potential probe for in vivo imaging of breast cancer.

Abstract
Esophageal squamous cell carcinoma is the most common type of esophageal cancer in Eastern Europe and Asia, being the 6th most common cause of cancer deaths worldwide. The aim of this study was to analyze the expression of transmembrane serine protein in esophageal squamous cell carcinoma, and to correlate it with the clinical biological features of esophageal cancer. The expression of transmembrane protease serine 4 (TMPRSS4) mRNA and protein in carcinoma tissues and corresponding adjacent tissues and non-tumorous esophageal tissues was determined using PCR (qRT-PCR). The results show that both TMPRSS4 mRNA and protein expression were remarkably lower in adjacent normal tissues than in tumorous tissues. TMPRSS4 protein expression in esophageal carcinoma was correlated with patient demographic characteristics, tumor type, high TNM stages and overall survival (OS). Based on the experimental results, we conclude that TMPRSS4 is closely related to the occurrence, development and metastasis of esophageal squamous cell carcinoma.

Abstract
Objective: To examine the relationship between recovery experience, occupational stress, and physiological health of nurses in a municipal grade A tertiary hospital. Methods: A total of 296 in-service nurses from 7 municipal grade A tertiary hospitals were selected from October 2015 to February 2016. Individual characteristics of the subjects were collected using a self-made questionnaire. The recovery experience, occupational stress, and physiological health of the subjects were assessed based on the physiological health dimensions in the Chinese version of Recovery Experience Questionnaire (REQ-C) , Job Content Questionnaire (JCQ) , and Quality of Work Life (QWL7-32) . Results: The mean recovery experience score of nurses from the municipal grade A tertiary hospital was 45.04±7.72, and 51.35% of the nurses had satisfactory recovery experience. Occupational stress was identified in 81.76% of the nurses. Based on the four categories of occupational stress, 65 nurses were identified with high-strain jobs (21.95%) , 56 with relaxed (low-strain) jobs (18.92%) , 49 with passive jobs (16.55%) , and 126 with active jobs (42.57%) . In addition, the mean physiological health score of the nurses was 21.20±4.24. Physiological health was negatively correlated with occupational stress (r=-0.173, P<0.05) , but positively correlated with recovery experience (r=0.198, P<0.01) . Recovery experience was negatively correlated with occupational stress (r=-0.116, P<0.05) . Job demand was the major contributor to occupational stress, where subjects with high-demand active jobs had the poorest recovery experience (F=2.610, P<0.05) and physiological health (F=8.166, P<0.01) . Conclusion: Job demand has a great impact on the occupational stress of nurses, where increased job demand can lead to stronger stress response, reduced recovery experience, and poorer physiological health.

Abstract
Objective: To analyze the clinical and gene mutation characteristics of dynamin-1 (DNM1)-related infantile spasms. Method: Clinical, laboratory and genetic data of one case of DNM1-related infantile spasms diagnosed by Xiangya Hospital in September 2015 were analyzed.Through taking "Dynamin-1" "DNM1" as key words to search at CNKI, Wanfang, PubMed and OMIM to date (April 2016), the clinical characteristics of 9 reported cases of DNM1-related epileptic encephalopathy in international literature with our case were reviewed. Result: The boy is the second child of healthy and nonconsanguineous parents.At 7 months, he started to have seizures with head dropping, and he was brought for the first time to our hospital at the age of 17 months.The patient presented with severe psychomotor retardation, epilepsy, muscular hypotonia, and electroencephalography showed hypsarhythmia.He received 28 days of adrenocorticotropic hormone (ACTH) therapy.After that, his seizures were improved with valproic acid and levetiracetam, and disappeared between 3 years and 5 months to 5 years and 5 months of age on treatment with valproic acid only.Exome-sequencing study (trios) identified novel heterozygous mutation c. 443A>G (p.Glu148Arg) in DNM1. Up to now, 9 cases of epileptic encephalopathy (infantile spasms or Lennox-Gastaut syndrome) associated with de novo DNM1 gene mutations have been reported. Conclusion: The main clinical features of DNM1 mutations include intractable seizures, intellectual disability, developmental delay, hypotonia, and developmental delay before the onset of seizures.

Abstract
The epithelium is a highly dynamic system, which plays a crucial role in the homeostasis of the intestinal tract. However, studies on the physiological and pathophysiological functions of intestinal epithelial cells (IECs) have been hampered due to lack of normal epithelial cell models. In the present study, we established a reproducible method for primary culture of mouse IECs, which were isolated from the viable small intestinal crypts of murine fetuses (on embryonic day 19), using type I collagenase and hyaluronidase in a short span of time (≤20 min). With this method, continuously growing mouse IECs, which can be subcultured over a number of passages, were obtained. The obtained cell lines formed a tight cobblestone-like arrangement, displayed long and slender microvilli, expressed characteristic markers (cytokeratin 18 and Notch-1), and generated increasing transepithelial electrical resistance and low paracellular permeability during in vitro culture. The cells also had enzymatic activities of alkaline phosphatase and sucrase-isomaltase, and secreted various cytokines (IL-1β, IL-6, IL-8, and monocyte chemoattractant protein-1), responding to the stimulation of Escherichia coli. These results show that the primary-cultured mouse IECs obtained by the method established here had the morphological and immunological characteristics of IECs. This culture system can be a beneficial in vitro model for studies on mucosal immunology and toxicology.

Abstract
Objective: To explore clinical characteristics, treatment, and prognosis of a family with childhood-onset rapid-onset dystonia parkinsonism (RDP) caused by ATP1A3 gene mutation and review literatures. Method: The clinical data of a RDP child, his brother and mother had been analyzed retrospectively. This family was admitted to Xiangya Hospital in January 2016. DNA samples were analyzed by the next-generation sequencing and confirmed by Sanger sequencing. Related literature from PubMed, Online Mendelian Inheritance in Man (OMIM), CNKI and Wanfang databases to date (up to October 2016) with"Rapid-onset dystonia-parkinsonism""RDP""DYT12" as key words was reviewed. Result: The proband boy was three years and four months old (April 2015) when he had the first attack of the disease. After a febricity, he suddenly acquired acute aphasia and limb movement disorder. Rehabilitation therapy and supportive treatment made his speech gradually recovered but still slurred. However, his abnormal walking posture still existed. Nine months later (January 2016, 4 years and one months old), symptoms including aphasia, dysphagia, and weakness with rostrocaudal gradient reoccured after fever. The disease progressed to the critical condition within 24 hours. He"seizured" four times with tonic spasms of limbs but without loss of consciousness. Family history showed his grandparents were consanguineous marriage. His mother and brother also developed abnormal gait and dysarthria after an infection before primary school age. Their symptoms improved gradually without relapsing. However, they did not recover entirely with mild intellectual disability. His mother had a healthy brother and sister. This proband had no other siblings but the brother. Heterozygous missense mutation p. R756H in ATP1A3 gene was detected in this proband, his mother and his brother. This mutation had been reported pathogenically related to RDP, and it located in highly conserved gene region. Benzodiazepine was used for the proband and his brother, with the proband being improved better although not completely. Meanwhile, benzodiazepine had no significant effect on his mother because of poor compliance. This is the first case report of RDP in China. The mutations of ATP1A3 have been previously reported in 51 patients including 6 large families and 16 other unrelated patients. A total of 14 different mutations in ATP1A3 gene with RDP have been reported to date, including 12 missense mutations, a 3-bp in-frame deletion, and a 3-bp in-frame insertion. The sporadic cases all had the typical clinical phenotypes of RDP, such as the abrupt onset of dysarthria, dysphagia, limb dystonia with bradykinesia, and postural instability. The symptoms of bulbar and arms were much more obvious. It was hard to diagnose RDP in a family because some patients had typical symptoms of RDP, while the others might experience from mild symptoms to no symptoms, which might be related to incomplete penetrance of RDP. Two cases carrying the same mutation as our patients also presented some overlapping phenotypes. Conclusion: The p. R756H heterozygous mutation in ATP1A3 gene is the pathogenic mutation of RDP, analysis of genotype-phenotype correlations of RDP will be very important and meaningful.

Abstract
This paper aimed to analyze the clinical effects of Xianling Gubao capsules on the bone mineral density (BMD) of 94 patients with osteoporosis. After reviewing and analyzing the clinical information in our hospital from January 2015 to January 2016, the patients were divided into a control group and a treatment group with 47 cases in each group. Patients in the control group were treated with routine Western medicine, while the treatment group received Xianling Gubao capsules. Both groups were treated continuously for 3 courses (30 days each course) and had their BMD analyzed and compared. The effective rates of the treatment group and control group were 91.48% and 70.21%, respectively, with statistical significance (P less than 0.05). Compared with the same group before the treatment, the bone metabolic indexes (blood calcium, phosphorus, and alkaline phosphate) and the BMD of the femoral neck and lumbar vertebrae (L1-2, L3-4, L2-4) of both groups were all improved with statistical significance (P less than 0.05) after the treatment. The above indexes of the treatment group were all significantly higher than those of the control group, with statistical significance (P less than 0.05). Compared with the same group before treatment (P less than 0.05), the osteocalcin (OC) levels of both groups were increased, and the Cross-linked N-telopeptide of type 1 collagen (CTX-1) levels were decreased after the treatment. The OC level in the treatment group was higher when compared with the control group, while the CTX-1 level was lower compared to the control group (P less than 0.05). Moreover, no significant side-effects or adverse events were observed during the treatment and observation period. The Xianling Gubao Capsule possesses a therapeutic effect for BMD in osteoporosis patients, which can effectively increase their BMD, improve their bone metabolism, and control the loss of bone mass, therefore, can be used in clinical promotion and application.

Abstract
The amino acids in royal jelly (RJ) have a wide range of pharmacological and health-promoting functions in humans. Multiple studies on the amino acid quality and composition in RJ have investigated RJ harvested at 72 h after larval transfer. In contrast, the concentration of amino acids in RJ harvested before 72 h remains unknown. In this study, the concentration of free amino acids (FAAs) and total amino acids (TAAs) in RJ harvested at 13 time points between 24 and 72 h after transfer of ten Apis mellifera colonies were measured. Our results indicated that the most abundant FAAs were Pro, Phe, Lys, Glu, and Tyr, whereas the most abundant TAAs were Asp, Glu, Leu, Lys, and Val. The total FAA concentration in RJ increased with increasing harvest time, from 4.30 mg/g at 24 h to 9.48 mg/g at 72 h. In contrast, the variation in concentration of TAAs observed was a decrease-increase-decrease trend with 40 h (149.53 mg/g) and 52 h (169.62 mg/g) as inflection points. The highest and lowest concentrations of TAA were 197.96 and 121.32 mg/g at 24 and 72 h, respectively. To our knowledge, this is the first study to investigate the concentration changes of FAAs and TAAs prior to 72 h after transfer. Our results will provide theoretical support to guide production practices of beekeeping, as well as elucidate the relationship between the harvest time point and RJ content.

Abstract
OBJECTIVE To observe the effect of Tripterygium wilfordii polycoride (TWP) on ulcerative colitis (UC), and its intervention effect on toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88) signaling pathway, thus to investigate its possible mechanism. METHODS Trinitrobenzene sulfonic acid (TNBS)/ethanol enema method was used to set up the UC rat model. With random number table, 90 male Wistar rats were divided into normal control group, model group, TWP low, medium and high dose group (3, 6, 12 mg/kg, respectively) and azathioprine (AZA) group (6 mg/kg), with 15 rates in each group. Four days after enema, rates in each group were given corresponding drug lavage for 14 consecutive days. Disease activity index (DAI), colon gross morphological damage and histological grading of each group were observed. Using Western blot and reverse transcription (RT)-PCR method, the TLR4/MyD88 signaling pathway-related proteins in UC rat intestinal tissue were detected, namely TLR4, MyD88, tumor necrosis factor receptor related factor 6 (TRAF-6), nuclear factor kappa B (NF-κB), tumor necrosis factor alpha (TNF-α), and interleukin-1 beta (IL-1β). RESULTS The DAI, colon gross morphological damage, and histological grading of the model group were significantly higher than that of the normal control group (all P<0.01), indicating successful establishment of UC model. The DAI, colon gross morphological damage and histological grading of the TWP high dose group were lower than those of the model group (0.87±0.25 vs 1.60±0.76, 3.93±1.94 vs 5.40±2.21, 5.45±2.73 vs 13.27±3.50, P<0.05). Compared with the normal control group, the mRNA and protein expressions of TLR4, MyD88, TRAF-6, NF-κB, TNF-α, and IL-1β in the model group rats were significantly increased (all P<0.01); which were significantly decreased in the TWP high dose group compared with model group rats (mRNA: 2.166±0.475 vs 5.647±0.275, 1.295±0.087 vs 3.774±0.418, 1.125±0.188 vs 2.535±0.320, 1.201±0.152 vs 2.082±0.077, 1.525±0.218 vs 3.094±0.022, 1.797±0.257 vs 17.152±0.145; protein: 0.252±0.010 vs 0.277±0.008, 0.172±0.002 vs 0.213±0.005, 0.233±0.006 vs 0.248±0.003, 0.099±0.003 vs 0.122±0.007, 0.238±0.002 vs 0.252±0.005, 0.235±0.003 vs 0.245±0.006, all P<0.05), also decreased in the AZA group (all P<0.01); and there were no significant differences between the TWP high dose group and the AZA group (all P>0.05). CONCLUSIONS TWP can alleviate intestinal inflammation, promote healing of mucosa, showing a therapeutic effect for UC. One of its mechanisms may be through inhibiting the expression of TLR4, affecting the expression of TRAF-6, which is downstream to MyD66 signaling pathway, thus to suppress the activation of NF-κB and reduce the release of inflammatory factor such as TNF-α and IL-1β.

Abstract
In this work, we studied the phase transitions and exchange bias of Ni50−xMn36Sn14Tx (T = Pd, Pt; x = 0, 1, 2, 3) alloys. An intermartensitic transition (IMT), not observed in Ni50Mn36Sn14 alloy, was induced by the proper application of negative chemical pressure by Pd(Pt) doping in Ni50−xMn36Sn14Tx (T = Pd, Pt) alloys. IMT weakened and was suppressed with the increase of applied field; it also disappeared with further increase of Pd(Pt) content (x = 3 for Pd and x = 2 for Pt). Another striking result is that exchange bias effect, ascribed to the percolating ferromagnetic domains coexisting with spin glass phase, is notably enhanced by nonmagnetic Pd(Pt) addition. The increase of unidirectional anisotropy by the addition of Pd(Pt) impurities with strong spin-orbit coupling was explained by Dzyaloshinsky-Moriya interactions in spin glass phase.

Abstract
Sensing bitter tastes is crucial for most animals because it can prevent them from ingesting harmful food. This process is mainly mediated by the bitter taste receptors (T2R) that are largely expressed in the taste buds. Previous studies have identified some T2R gene repertoires. Marked variation in repertoire size has been noted among species. However, research on T2Rs is still limited and the mechanisms underlying the evolution of vertebrate T2Rs remain poorly understood. In the present study, we analyzed the structure and features of the protein encoded by the forest musk deer (Moschus berezovskii) T2R16 and submitted the gene sequence to NCBI GenBank. The results showed that the full coding DNA sequence (CDS) of musk deer T2R16 (GenBank accession No. KP677279) was 906 bp, encoding 301 amino acids, which contained ATG start codon and TGA stop codon, with a calculated molecular weight of 35.03 kDa and an isoelectric point of 9.56. The T2R16 protein receptor had seven conserved transmembrane regions. Hydrophobicity analysis showed that most amino acid residues in T2R16 protein were hydrophobic, and the grand average of hydrophobicity (GRAVY) was 0.657. Phylogenetic analysis based on this gene revealed that forest musk deer had the closest association with sheep (Ovis aries), as compared to cow (Bos taurus), Tursiops truncatus, and other species, whereas it was genetically farthest from humans (Homo sapiens). We hope these results would complement the existing data on T2R16 and encourage further research in this respect.

Abstract
Domestic goats are important meat production animals; however, data from transcriptional profiling of skeletal muscle tissue in goat have thus far been scarce. We used comparative transcriptional profiling based on RNA sequencing of longissimus thoracis muscle tissue obtained from fetal goat muscle tissue (27 512 850 clean cDNA reads) and 6-month-old goat muscle tissue (27 582 908 reads) to identify genes that are differentially expressed, novel transcript units and alternative splicing events. Gene annotation revealed that 15 960 and 14 981 genes were expressed in the fetal and juvenile libraries respectively. We detected 6432 differentially expressed genes and, when considering GO terms, found 34, 27 and 55 terms to be significantly enriched in molecular function, cellular component and biological process categories respectively. Pathway analysis revealed that larger numbers of differentially expressed genes were enriched in fetal myogenesis or cell proliferation and differentiation-related pathways (such as Wnt), genes involved in the cell cycle and the Notch signaling pathway, and most of the differentially expressed genes involved in these pathways were downregulated in the juvenile goat library. These genes may be involved in various regulation mechanisms during muscle tissue differentiation between the two development stages examined herein. The identified novel transcript units, including both non-coding and coding RNA, as well as alternative splicing events increase the level of complexity of regulation mechanisms during muscle tissue formation and differentiation. Our study provides a comparative transcriptome analysis on goat muscle tissue, which will provide a valuable genomic resource for future studies investigating the molecular basis of skeletal muscle development.

Abstract
WHAT IS KNOWN AND OBJECTIVE The Adverse Drug Reaction Information Bulletin (ADRIB), issued by China Food and Drug Administration (CFDA), is a major source of information on drugs causing safety concerns in China. As the publication is only published in Chinese, we undertook an analysis of the reports in the ADRIB since its first publication in 2001 to give international readers a better appreciation of the pharmacovigilance issues addressed. METHODS Every issue of the ADRIB was scrutinized, and the issues addressed as well as the drugs involved are summarized and discussed. RESULTS AND DISCUSSION From 2001 to 2014, 109 items of ADR information have been reported. The antimicrobial agents were most often the subject of discussion. There were 28 traditional Chinese medicines (TCMs) discussed. Among the ADRs addressed, the adverse reactions of the skin and its appendages were most frequent. About two-fifths of the ADRs arose from the inherent properties of the active substance, and a majority of the ADRs were caused by off-label use, irrational drug combinations and misuse in special populations. WHAT IS NEW AND CONCLUSION Many of the pharmacovigilance issues addressed were similar to those considered by Western Drug Regulatory Agencies. The pharmacovigilance issues relating to Chinese traditional medicines are less well addressed internationally, and these would be of particular value as the use of such medicines increases in the West.
