Abstract
Objective: To investigate the effect of global end-diastolic volume index (GEDI)-guided fluid resuscitation on the prognosis of patients with chronic heart failure and septic shock. Methods: This study was a prospective randomized controlled study. Consecutive eligible patients were divided into 2 groups according to the random number table method: control group (n=21) and experimental group (n=20). On the basis of routine treatment, patients in the control group received early goal-directed therapy until the central venous pressure (CVP) reaching 8-12 mmHg (1 mmHg=0.133 kPa), mean arterial pressure reaching over 65 mmHg, urine volume reaching over 0.5 ml·kg(-1)·h(-1), and central venous oxygen saturation reaching more than 70%. On the basis of routine treatment, patients in the experimental group were monitored continuously on cardiac output with pulse indication and fluid resuscitation guided by volume index GEDI. The GEDI should be maintained on the range of 680-800 ml/m(2). The remaining resuscitation goals were the same as control group. General clinical data of the two groups were collected at admission. Negative fluid balance onset time, duration of mechanical ventilation, ICU mortality and 28-day mortality were compared between the two groups. The outcomes were recorded as listed: start time of negative fluid balance, duration of mechanical ventilation, mortality in ICU and 28-day mortality. Results: There was no significant difference in age, sex, weight, APACHE Ⅱ score, SOFA score and NYHA functional class score between the two groups (all P>0.05). The negative liquid balance onset time in the control group was 3.5 (2.5, 4.0) days, which was significantly longer than that in the experimental group (2.6 (2.0, 3.0) days,U=115.0, P=0.012). The duration of mechanical ventilation was 355 (118, 552) hours in the control group, which was significantly longer than that in the experimental group (132 (36.75, 233.3) hours, U=130, P=0.038). The ICU mortality was 38.1% (8/21) in the control group, tended to be higher than that in the experimental group (20.0%(4/20), χ(2)=1.620, P=0.203). The 28-day mortality was 42.9% (9/21) in the control group, similar as in the experimental group (25.0%(5/20), χ(2)=1.482,P=0.477). Conclusion: Fluid resuscitation guided by volume index (GEDI) may improve the prognosis of patients with chronic heart failure complicated with septic shock.

Abstract
Objective: To investigate histopathological characteristics, and differential diagnoses of childhood synovial sarcoma. Methods: HE staining, immunohistochemical staining and fusion gene detection by FISH were performed in 12 cases of synovial sarcoma in childhood at Beijing Children's Hospital from 2016 to 2018. Results: There were 6 cases of biphasic type, 1 case of monophasic epithelial type, 3 cases of monophasic spindle cell type and 2 cases of poorly differentiated synovial sarcomas. EMA, CKpan, bcl-2, CD99, TLE1 and CD34 immunostain positivities were observed in 10/12, 9/12, 12/12, 10/12, 10/12 and 0/12 cases respectively. Unique INI1 immunohistochemical staining was observed in 9/12 cases. SS18-SSX gene fusion was detected in 8 of 11 cases by FISH. Conclusions: Synovial sarcoma is rare in children. Histological morphology combined with immunohistochemistry and FISH SS18-SSX fusion gene detection are important for the diagnosis and differential diagnosis of synovial sarcoma in children.

Abstract
A survey was conducted to analyze the HIV testing status and related influencing factors of male sexually transmitted diseases(STD) patients attending 18 county-level hospitals in Shandong Province from July 2015 to August 2016. The HIV detection rate of 1 570 subjects was 77.58% (1 218/1 570), and the HIV-antibody positive rate was 0.99% (12/1 218). Compared with general hospitals patients, urinary and anorectal patients, non-sexual patients, and patients with negative attitudes toward HIV testing, patients were more likely to be tested for HIV from specialized hospitals (OR=3.74, 95%CI:2.53-5.54), the skin and venereal section (OR=1.92, 95%CI: 1.31-2.79), the STD group (OR=2.02, 95%CI: 1.34-3.03) and patients with positive attitude (OR=15.20, 95%CI:10.74-21.52).

Abstract
Objective: To investigate the food source of water of college students from Hebei Province in spring. Methods: In March 2017, the subjects were recruited in a college in Baoding, Hebei Province. 156 students completed the investigation. All foods were collected for 3 consecutive days using duplicate portion study combined with weighing method to test the water content of various foods. To analyze the water content of the food and calculate the proportion to the total amount of food water intake, the edible parts of each meal were divided into staple food, dishes, porridge, soup and snacks. Body mass index (BMI) was grouped according to quartiles, and the differences in food intake and food water sources among subjects of different genders and BMI were compared. Results: The age of subjects was (19.8±1.1) years old, including 80 male students. The median intake of staple food, dishes, porridge, soup and snacks per day was 562 g, 743 g, 111 g, 102 g and 0 g, respectively. The median intake of water from staple food, dishes, porridge, soup and snacks per day was 301 ml/d, 620 ml/d, 97 ml/d, 93 ml/d and 0 ml/d, respectively. The median ratio of water intake to total food water intake of staple food, dishes, porridge, soup and snacks was 27%, 53%, 8%, 8% and 0%, respectively. The median intake of water from staple food and dishes in male students was significantly higher than that of female students (P<0.05). The amount of water intake from porridge of female students was significantly higher than that of male students (P<0.05). There was no significant difference in the water intake from soup and snacks between different genders. There was no significant difference in food intake and food water sources among college students with different BMI (P>0.05). Conclusion: The food source of water of college students from Hebei Province in spring is mainly based on dishes and staple foods. The food source of water for boys and girls is different.

Abstract
At present, methods of water-intake survey include government, industry, sector statistics data, dietary survey (24 hours dietary recall, dietary record and food frequency questionnaire), fluid intake survey (retrospective fluid-intake questionnaire, 1-5 days 24 hours fluid-intake survey, 7 days 24 hours fluid-intake record), weighing method with the food composition table, weighing method, duplicate portion method and chemical analysis, and so on. The method of 7 days 24 hours fluid-intake record is an internationally recognized and authoritative method for fluid-intake survey with the highest accuracy, which can reflect the differences of fluid intake between working and non-working days, and can obtain detailed data on behaviors and patterns of fluid water, such as the time, types and places of fluid intake. The method of combining weighing method, duplicate portion method and chemical analysis is used to analyze water intake from food with the highest accuracy, which can be used in an extensive range of population and areas, but with high cost and complex operating steps. It is of great practical significance to compare and evaluate the advantages and disadvantages of different methods about water-intake survey, which will be helpful for researchers to choose appropriate methods for water-intake survey to obtain accurate and representative data in various areas, different population, and complex circumstances.

Abstract
Objective: To investigate the effects of different expression of monoacylglycerol lipase (MAGL) in tumor-associated macrophages (TAMs) with the proliferation of MHCC97H human liver cancer cells in vivo and its mechanism. Methods: Human peripheral blood-derived monocyte was induced to differentiate into M2-type TAMs and was identified by flow cytometry. The co-culture model of TAMs and MHCC97H human liver cancer cells was established, and the expression of MAGL in TAMs cells was detected by qRT-PCR. The expression of MAGL in TAMs cells was detected by plasmid transfection. ELISA and qRT-PCR was used to detect the mRNA expression levels and secretion levels of inflammatory factors in TAMs cells. The subcutaneous tumor model of MHCC97H mice was constructed to observe the effect of different expression of MAGL in TAMs cells with the proliferation of MHCC97H human liver cancer cells in vivo. F-test was used for the measurement of homogeneity of variance between two independent samples. A t-test was used for homogeneity of variance, and the corrected t-test was used for non-homogeneity of variance. Results: Human peripheral blood-derived monocytes were successfully induced to differentiate into M2-type TAMs. An in vitro co-culture model was established. qRT-PCR showed that MHCC97H human liver cancer cells significantly down-regulated the expressional level of MAGL in TAMs cells. The constructed subcutaneous tumor model of mice demonstrated that up-regulation up-regulation of MAGL expression in M2-type TAMs inhibited the proliferation of MHCC97H human liver cancer cells in vivo. Furthermore, the mechanistic study illustrated that the high expression of MAGL promoted the transcription and secretion of inflammatory factors such as interleukin-1 beta, interleukin-6 and tumor necrosis factor-alpha in M2-type TAMs cells. Conclusion: The overexpression of MAGL inhibits the proliferation of MHCC97H hepatocellular carcinoma cells in vivo, and its mechanism may be associated to the release of inflammatory factors that from TAMs cells.

Abstract
At present, there is no accurate and effective method for treating neoplastic pericardial effusion. This study analyzed the current literature on the treatment of neoplastic pericardial effusion to provide advice and guidance for clinical treatment. Surgical treatments include pericardial puncture, extension of catheter drainage, pericardial window, and surgical pericardiotomy. Each surgical procedure has a corresponding indication, and the best treatment is selected according to the patient's specific conditions. Systemic chemotherapy is effective in lymphoma and small cell lung cancer that are sensitive to chemotherapeutic drugs. Although pericardial injection of drugs is effective for pericardial tamponade and recurrent pericardial effusion, these methods can only temporarily relieve symptoms and cannot prolong the life of patients. In recent years, immunotherapy, especially adoptive immunotherapy, has achieved good results in the treatment of neoplastic pericardial effusion, thus providing a novel treatment option for neoplastic pericardial effusion.

Abstract
BACKGROUND AND PURPOSE The cerebellum plays an important role in motor and cognitive functions. However, whether and how the normal-appearing cerebellum is impaired in patients with neuromyelitis optica spectrum disorders remain unknown. We aimed to identify the occult structural damage of the cerebellum in neuromyelitis optica spectrum disorder and its possible causes at the level of substructures. MATERIALS AND METHODS Normal-appearing gray matter volume of the cerebellar lobules and nuclei and normal-appearing white matter volume of the cerebellar peduncles were compared between patients with neuromyelitis optica spectrum disorder and healthy controls. RESULTS The cerebellar damage of patients with neuromyelitis optica spectrum disorder in the hemispheric lobule VI, vermis lobule VI, and all cerebellar nuclei and peduncles was related only to spinal lesions; and cerebellar damage in the hemispheric lobules VIII and X was related only to the aquaporin-4 antibody. The mixed cerebellar damage in the hemispheric lobules V and IX and vermis lobule Crus I was related mainly to spinal lesions; and mixed cerebellar damage in the hemispheric lobule VIIb was related mainly to the aquaporin-4 antibody. Other cerebellar substructures showed no significant cerebellar damage. CONCLUSIONS We have shown that the damage in cerebellar normal-appearing white matter and normal-appearing gray matter is associated with aquaporin-4-mediated primary damage or axonal degeneration secondary to spinal lesions or both. The etiologic classifications of substructure-specific occult cerebellar damage may facilitate developing neuroimaging markers for assessing the severity and the results of therapy of neuromyelitis optica spectrum disorder occult cerebellar damage.

Abstract
BACKGROUND Surgery is becoming more practical and effective than conservative treatment in improving the poor outcomes of patients with breast cancer liver metastasis (BCLM). However, there is no generally acknowledged set of standards for identifying BCLM candidates who will benefit from surgery. METHODS Between January 2011 and September 2018, 67 female BCLM patients who underwent partial hepatectomy were selected for analysis in the present study. Prognostic factors after hepatectomy were determined. Univariate and multivariate analyses were performed to identify predictors of overall survival (OS) and intrahepatic recurrence-free survival (IHRFS). RESULTS The 1-, 3- and 5-year OS of patients treated with surgery was 93.5%, 73.7% and 32.2%, respectively, with a median survival time of 57.59 months. The Pringle manoeuvre [hazard radio (HR) = 0.117, 95% CI0.015-0.942, p = 0.044] and an increased interval between breast surgery and BCLM diagnosis (HR0.178, 95% CI 0.037-0.869, p = 0.033) independently predicted improved overall survival for BCLM patients. The 1-, 2- and 3-year IHRFS of patients who underwent surgery was 62.8, 32.6% and 10.9%, respectively, with a median intrahepatic recurrence-free survival time of 13.47 months. Moderately differentiated tumours (HR 0.259, 95% CI 0.078-0.857, p = 0.027) and the development of liver metastasis more than 2 years after breast surgery (HR 0.270, 95% CI 0.108-0.675, p = 0.005) might be predictors of increased IHRFS. CONCLUSIONS An interval of more than 2 years between breast cancer surgery and liver metastasis seems to be an indication of liver surgery in BCLM patients. The Pringle manoeuvre and moderately differentiated tumours are potential predictors associated with OS and IHRFS, respectively, as benefits from liver resection. Studies with increased sample sizes are warranted to validate our results.

Abstract
Background Psoriasis is a chronic skin disorder that manifests as epidermal keratinocyte hyperplasia. Objectives We examined the effect of oxymatrine treatment on cell proliferation and apoptosis in skin lesions of psoriasis. Patients and methods Patients with severe plaque psoriasis were treated with oxymatrine or with acitretin. The skin lesions were stained with proliferating cell nuclear antigen (PCNA), Ki‐67 and Bcl‐2, as well as examined by terminal deoxynucleotidyl transferase‐mediated dUTP nick‐end labelling (TUNEL). We performed correlations of the Psoriasis Area and Severity Index (PASI) and the proliferation and apoptosis index. Results Oxymatrine significantly reduced the psoriasis lesions as demonstrated by the reduced PASI score after treatment [6·91; 95% confidence interval (CI) 5·00–8·81, P < 0·001]. In the oxymatrine group, the mitotic index was 26·15 (95% CI 24·80–27·49) before oxymatrine treatment, decreasing to 14·52 (95% CI 13·82–15·25; P < 0·001) after treatment, but remained higher than the normal group (6·24; 95% CI 5·87–6·61, P < 0·001). Oxymatrine also inhibited the proliferation of epidermal cells in the skin lesion as indicated by the reduced proliferation index after treatment (P < 0·01). In addition, oxymatrine treatment reduced cellular apoptosis as shown by increased Bcl‐2 expression and a decrease in TUNEL‐positive cells. The PASI score was positively correlated with mitotic index, proliferation index and apoptotic index (TUNEL), but negatively correlated with Bcl‐2 expression. Conclusions Oxymatrine treatment reduced proliferation but inhibited apoptosis of cells in the skin lesion. The balance between cell proliferation and turnover may contribute to the significant alleviation of psoriasis by oxymatrine. What's already known about this topic? Psoriasis manifests as epidermal keratinocyte hyperplasia with proliferation, keratinocyte maturation and turnover rates. Current drugs for psoriasis may inhibit cell proliferation but could not adjust the balance of cell division, differentiation and apoptosis.
What does this study add? We studied the efficacy of oxymatrine in the treatment of psoriasis and analysed the correlation of skin lesions, proliferation and apoptosis index before and after oxymatrine treatment.
What is the translational message? Our study has demonstrated that oxymatrine is effective in the treatment of severe plaque psoriasis. It has comparable efficacy with acitretin. Because acitretin treatment was sometimes associated with metabolic abnormalities, our study suggests oxymatrine therapy as an alternative treatment for psoriasis in the context of acitretin allergy or adverse reactions.

Abstract
Objective: To explore the association between frailty and muscle performances of hospitalized elder adults with coronary artery disease. Methods: A total of 122 hospitalized patients aged 65-85 years old with coronary artery disease from Department of Geriatrics and Cardiology, Peking Union Medical College Hospital between December 2017 and March 2018 were enrolled in the study. A comprehensive geriatric assessment was performed to evaluate existing comorbidity and geriatric syndromes of the patients. Frailty was assessed using the Clinical Fraity Scale. The patients were classified as frail and non-frail, according to the scale. Muscle performances were assessed using grip strength, gait speed, etc. Whole body and appendicular skeletal muscle mass was detected with bioelectrical impedance analysis in patients with reduced grip strength or slowed gait speed. Appendicular skeletal muscle index (ASMI) was calculated. Results: Among all subjects, 28 were with frailty (23.0%) and 94 were without (77.0%). The frail patients were older [(76.7±5.4) years vs. (72.2±5.6)years], had higher Charlson comorbidity index [2.0(1.0,2.75)vs. 1.0(0,2.0)], and higher proportion of malnutrition (14.29% vs. 1.06%), urinary incontinence (39.29% vs. 15.96%), using walking-aid (28.57% vs. 6.38%), and more kinds of taken drugs (8.1±3.0 vs. 6.6±2.7), than the non-frail patients. Prealbumin levels [(207.8±60.0)mg/L vs.(234.3±45.4)mg/L] were lower, and highly sensitive C-reactive protein levels [(5.89±9.57)mg/L vs.(1.89±2.49)mg/L] were higher in the frail patients than in the non-frail patients (all P<0.05). Compared with non-frail patients, the frail patients had poorer grip strength [(19.67±7)kg vs.(29.23±8.29)kg] and slower gait speed [(0.54±0.2)m/s vs.(0.91±0.22)m/s] (all P<0.001). Spearman rank correlation analyses showed that grip strength was positively correlated with the appendicular skeletal muscle mass(r=0.811), whole body skeletal muscle mass(r=0.74) and the ASMI (r=0.783), respectively. Conclusions: The incidence of frailty among hospitalized older adults with coronary artery disease is high. Poor muscle performances were common in these patients. Assessment of frailty and muscle performances can help to evaluate the overall function of older adults with cardiovascular disease in a comprehensive way.

Abstract
Objective: To investigate the relationship between duration of sleep and all-cause mortality in patients with type 2 diabetes. Methods: A total of 17 452 type 2 diabetic patients who were under the National Basic Public Health Service Project, in Changshu county, Qinghe district and Huai'an district in Huai'an city of Jiangsu province, were recruited as participants. Cox proportional hazards regression models were used to estimate the associations between different levels on the duration of sleep and all-cause mortality. Stratified analysis was performed according to factors as gender, age, and lifestyle. Results: Among the 67 912 person-years of observation, from the fo1low- up program, the median time of follow-up was 4 years, with 1 057 deaths occurred during the follow-up period. Taking patients with duration of sleep as 7 h/d for reference, the multivariate adjusted hazard ratios (95%CI) of all-cause mortality appeared as ≤6, 8, 9 and ≥10 h/d were 1.14 (0.94-1.37), 1.10 (0.91-1.32), 1.33 (1.05-1.70), and 1.52 (1.24-1.87), respectively which were associated with the duration of sleep. Data from the subgroup analysis showed that this was consistent with the whole population. Longer duration of sleep was associated with the all-cause mortality but no significant association was found between shorter duration of sleep and the all-cause mortality. Conclusion: Longer duration of sleep seemed to have increased the risk of all-cause mortality in type 2 diabetic patients.

Abstract
Objectives: To investigate the total fluids intake among college students in spring from Hebei. Methods: In March 2017, the subjects were recruited in a college in Baoding, Hebei Province. 156 students completed the investigation. Total drinking fluids was assessed by 7-day 24-hour fluid intake questionnaire, with a quantitative tool. The water from food was assessed by duplicate portion method. The sources of total fluids intake among subjects were analysed. Results: The age of subjects was (19.8±1.1) years old, including 80 male students. The median amounts of total fluids intake, total drinking fluids and water from food were 2 324, 1 135 and 1 174 ml, respectively. The proportions of total drinking fluids and water from food in total fluids intake were 51%±9% and 49%±10%. Only 19.9% (n=31) and 18.6% (n=29) of college students had adequate total fluids intake and total drinking fluids, according to the recommendation of China. The median amounts of total fluids intake, total drinking fluids and water from food were 3 210, 1 860 and 1 093 ml/d, respectively. The proportion of total drinking fluids in total fluids intake was 61%±7%, which were all higher than those who did not reach the recommended intake (2 158, 1 000, 1 149 ml/d; drinking fluids accounting for 46%±8% of total fluids intake) (P<0.05). Conclusion: The amounts of total fluids intake and total drinking fluids of college students in Hebei Province are lower than the recommended intake in China. The contributions of total drinking fluids and water from food to total fluids intake were nearly same.

Abstract
Objective: To analyze the influencing factors on condom use among 35-years-or-older female sex workers (OFSWs) in Qingdao by using the three-level logistic model. Methods: From March to June 2014, OFSWs were recruited in Qingdao, using respondent-driven sampling. Related information on OFSWs and their recent five sexual partners (not including husband) were obtained by conducting a questionnaire survey on OFSWs. A Three-level logistic regression model was conducted to analyze the influencing factors of condom use between OFSWs and their sexual partners. Results: A total of 420 OFSWs participated the survey as well as information on 2 100 sexual partners. Results from the empty model showed that the use of condoms among OFSWs having an aggregation that related to the levels of working sites and their own behaviors. Results from the three-levels of logistic model analysis showed that, OFSWs that having had junior middle school education (OR=1.450, 95%CI: 1.054-1.994)/high school education or above (OR=2.264, 95%CI: 1.215-4.222), knowing the function of condom use (OR=2.004, 95%CI: 1.273-3.154) would have higher rates of condom use. OFSWs with higher score of attitude on condom use (OR=0.796, 95%CI: 0.745-0.849), having had syphilis infections in the past (OR=0.657, 95%CI: 0.478-0.902) would have lower rate of condom use. For the sexual partners, the rate of condom use among OFSWs' regular partners were higher than that of OFSWs' boyfriends (OR=15.291, 95%CI: 8.441-27.700; OR=29.032, 95%CI: 15.413-54.682). Conclusion: Condom use of OFSWs was affected by behaviors of both OFSWs themselves and their sexual partners. Prevention and control programs should focus on OFSWs and their sexual partners at the same time. The key intervention contents should include target populations as: OFSWs with low level of education, having had infections of syphilis, those who do not use condoms with their trusted partners.

Abstract
BACKGROUND We conducted a single-arm phase II trial to evaluate the efficacy and adverse effects (AEs) of an anti-epidermal growth factor receptor monoclonal antibody, nimotuzumab, combined with cisplatin and 5-fluorouracil (PF) as first-line treatment in recurrent metastatic nasopharyngeal carcinoma after radical radiotherapy. METHODS Patients who met the eligibility criteria were recruited from ten institutions (ClinicalTrials.gov; NCT01616849). A Simon optimal two-stage design was used to calculate the sample size. All patients received weekly nimotuzumab (200 mg) added to cisplatin (100 mg/m2 D1) and 5-fluorouracil (4 g/m2 continuous infusion D1-4) every 3-weekly for a maximum of six cycles. Primary end point was objective response rate (ORR). Secondary end points included disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and AEs. RESULTS A total of 35 patients were enrolled (13 in stage 1 and 22 in stage 2). Overall ORR and DCR were 71.4% (25/35) and 85.7% (30/35), respectively. Median PFS and OS were 7.0 (95% CI 5.8-8.2) months and 16.3 (95% CI 11.4-21.3) months, respectively. Unplanned exploratory analyses suggest that patients who received ≥2400 mg nimotuzumab and ≥4 cycles of PF had superior ORR, PFS and OS than those who did not (88.9% versus 12.5%, P < 0.001; 7.4 versus 2.7 months, P = 0.081; 17.0 versus 8.0 months, P = 0.202). Favourable subgroups included patients with lung metastasis [HROS 0.324 (95% CI 0.146-0.717), P = 0.008] and disease-free interval of >12 months [HROS 0.307 (95% CI 0.131-0.724), P = 0.004], but no difference was observed for metastatic burden. The only major grade 3/4 AE was leukopenia (62.9%). CONCLUSION Combination nimotuzumab-PF chemotherapy demonstrates potential efficacy, and is well tolerated as first-line chemotherapy regimen in recurrent metastatic nasopharyngeal carcinoma.

Abstract
OBJECTIVES To investigate the value of optical coherence tomography (OCT) in the diagnosis of coronary atherosclerosis and myocardial infarction in forensic identification. METHODS OCT and hematoxylin-eosin (HE) examination were performed to examine the pathological samples of coronary artery and myocardial infarction in 5 cases of sudden coronary death. The morphological and local measurement indexes were compared. RESULTS In the OCT images, the layers of coronary artery could be distinguishably featured, and the atheroma plaques had a good morphological correspondence with HE slices. The normal myocardia in the OCT image showed weak light signals with high absorbance, while the fiber scar tissues in the myocardial infarction areas showed strong light signals with low absorbance. There were no significant differences on the fibrous cap thickness in coronary atherosclerotic plaques or intima-media thickness between the OCT images and the HE slices (P>0.05). In the OCT images, the optical densities of the old myocardial infarction areas (1 226.24±622.66) and those of normal myocardia (3 707.90±962.98) were significantly different ( P<0.05). CONCLUSIONS The OCT image has a good morphological consistency with HE slice, thus is expected to be the primary screening method for the forensic pathology examination of coronary artery atherosclerosis and myocardial infarction, which can help to improve the diagnostic accuracy.

Abstract
Objective: To compare the etiology and incidence of pulmonary infection in patients with esophageal carcinoma accompanied by esophagotracheal fistula before and after the airway stent implantation. Methods: The clinical records of patients with esophageal carcinoma accompanied by esophagotracheal fistula in Respiratory Department and Oncology Department of Meitan General Hospital were retrospectively analyzed from March 2008 to January 2018. The demographic data, comorbidities, pathological results and etiology were collected before and after tracheal stents were implanted in all patients. The incidence of pulmonary infection was analyzed, and the classification of etiology was compared before and after tracheal stents implantation. Results: A total of 100 patients were included in the study. The incidence rate of pulmonary infection before stents implantation was 83.0%. A total of 105 bacterial strains were cultured, including 73 strains of gram-negative bacteria (69.5%) and mainly pseudomonas aeruginosa, 5 strains of gram-positive bacteria [all methicillin-resistant staphylococcus aureus (MRSA)] (4.8%), and 27 strains of fungi (25.7%) and mainly candida albicans. The incidence rate of pulmonary infection was lowered to 53.0% after tracheal stents implantation (χ(2)=29.102, P<0.001). A total of 79 bacterial strains were cultured, and the main bacteria were still gram-negative bacteria and fungi, in which pseudomonas aeruginosa and candida albicans accounted for the majority. However, 13 strains of MRSA were cultured (16.5%), significantly higher than those before stents implantation (χ(2)=7.451, P=0.005). Conclusions: The incidence rate of pulmonary infection in patients with esophageal carcinoma accompanied by esophagotracheal fistula is very high. Gram-negative bacteria and fungi are the main etiologies. Tracheal stents implantation can effectively reduce the incidence of pulmonary infection. However, the incidence rate of MRSA is significantly increased after stents implantation.

Abstract
Objective: To analyze the epidemic features of male HIV-infected and AIDS patients by sexual transmission in Shandong Province. Methods: Data on HIV-infected people and AIDS patients (HIV/AIDS) were derived from HIV/AIDS Comprehensive Response Information Management System. To analysis the epidemiological data of male HIV/AIDS by sexual transmission reported in Shandong Province from 1997 to 2016. Results: A total of 8 584 HIV/AIDS were reported by heterosexual transmission or homosexual transmission from 2007 to 2016. 2 421 cases were reported by heterosexual transmission and 6 163 cases were reported by homosexual transmission. Among cases infected by heterosexual transmission. The average age of cases infected by heterosexual transmission was (38.13±12.39) and (31.62±10.22) among cases who infected by homosexual transmission (t=24.95, P<0.001). 84 cases were reported by homosexual transmission and 138 cases by heterosexual transmission from 2007 to 2008, and 6 079 cases were reported by homosexual transmission and 2 283 cases by heterosexual transmission from 2009 to 2016. A total of 770 cases were dead after reported. Among the dead cases, 337 cases were infected by homosexual transmission and 433 cases by heterosexual transmission (χ(2)=328.21, P<0.001). 61.4% of the dead cases by heterosexual transmission were no longer than 6 months after reported and 54.3% in homosexual transmission (χ(2)=3.96, P=0.047). Conclusion: Homosexual transmission has been the main transmission of HIV/AIDS in Shandong Province. Epidemiological features and social demographic characteristics of each sexual transmission were different. As part of HIV cases developed to death in 6 months.

Abstract
Sarcopenia is a common geriatric syndrome characterized by progressive decrease of muscle mass and function leading to an increased risk of physical disability, poor quality of life, and mortality. Increasing evidence shows that sarcopenia is related with fragility fractures. This systematic review aimed to summarize the following: (1) the prevalence of sarcopenia in patients with fragility fracture and (2) the associated risk factors for fragility fracture in patients with sarcopenia. Literature search was conducted in PubMed and Cochrane databases. Studies with the prevalence of sarcopenia in elderly patients with fragility fracture and associated risk factors in patients with sarcopenia were included. A total of 15 papers were included, with 10 reporting sarcopenia prevalence, and 5 on fracture risk in patients with sarcopenia. The prevalence of sarcopenia after fracture ranged from 12.4 to 95% in males and 18.3 to 64% in females. The prevalence of sarcopenia in elderly patients with fragility fracture was high, especially in men. Two studies showed that sarcopenia was a risk factor for fragility fracture when associated with low bone mineral density (BMD) but only in men. Caution should be taken for male patients with sarcopenia and low BMD, which is related to significantly increased risk of fractures. There is a pressing need for further research on sarcopenia and its risk on fragility fracture to better understand the relationship, pathophysiology, and mechanisms, which may shed light on potential interventions to improve clinical outcomes.

Abstract
Objective: To explore the causes of secondary drug resistance among HIV infected persons who were receiving antiretroviral therapy in Shandong province, and provide evidence for the improvement of antiretroviral therapy strategy. Methods: A case-control study was designed with 1∶2 matching on case and control groups. Household and face-to-face interview were conducted in October, 2015. All the study subjects were screened from both the drug resistant database of antiretroviral therapy of Shandong provincial laboratory and national comprehensive HIV/AIDS database in Shandong. The sample size was estimated as 330 cases including 110 drug resistant and 220 non-drug resistant cases. Subjects were people living with HIV/AIDS (PLWHA) aged 15 or older and received antiretroviral therapy for more than 6 months with records of virus load (VL). Subjects who presented VL above 1 000 copies/ml would receive drug resistance testing. Subjects who were confirmed resistant to with secondary drug, were selected as case group, the rest subjects with non-secondary drug resistance would form the control group. EpiData 3.1 software and SPSS 22.0 software were used to establish a database. Related influencing factors were analyzed with non- conditional stepwise logistic regression model. Results: A total of 288 cases were enrolled, including 103 in the case and 185 cases in the control groups, with average age as (37.62±1.06) years and (37.90±0.74) years old, respectively. Most of them were male, married/cohabitant, with education level of junior/senior high school or below and under Han nationality. Results from the multivariate logistic regression model showed that ORs (95%CI) of receiving antiretroviral therapy for 1-3 years, or more than 3 years were equal to 8.80 (3.69-21.00), 3.00 (1.20-7.53), compared with receiving antiretroviral therapy less than one year, respectively. OR (95%CI) of Among the PLWHA that with missing rate above 25.0% on medication, the OR appeared as 15.41(4.59-51.71), compared with not missing medication. OR (95%CI) among those who took the medicine themselves was 0.22 (0.07-0.74). Conclusions: Factors as duration of treatment, missing rate on medication and taking medicine by oneself were of influence on secondary drug resistance. Other factors as duration on antiretroviral therapy longer than 1 year, missing rate above 25.0% on medication, were related to the risk on secondary drug resistance. However, if the medicine was taken by oneself, it served as a protective factor for secondary drug resistance. It is necessary to strengthen the intervention and health education programs related to antiretroviral therapy.

Abstract
Objective: To understand the survival status and influencing factors for HIV/AIDS patients on highly active anti-retroviral therapy (HAART) in Shandong province. Methods: Both Kaplan-Meier (K-M) method and cumulative incidence function (CIF) were used to calculate the cumulative incidence of AIDS-related death respectively, and Fine-Gray model was used to identify the influencing factors related to survival time. Results: Through K-M method, a higher AIDS-related cumulated death rate than the CIF, was estimated. Among all the HIV/AIDS patients who initiated HAART from 2003 to 2015 in Shandong, 5 593 of them met the inclusion criteria. The cumulative incidence rate for AIDS-related death was 3.08% in 1 year, 4.21% in 3 years, 5.37% in 5 years, and 7.59% in 10 years respectively by CIF. Results from the F-G analysis showed that HIV/AIDS patients who were on HAART, the ones who had college degree or above (HR=0.40, 95%CI: 0.24-0.65) were less likely to die of AIDS-associated diseases. However, HIV/AIDS patients who were on HAART and living in the western areas of Shandong (HR=1.33, 95%CI: 1.01-1.89), diagnosed by medical institutions (HR=1.39, 95%CI: 1.06-1.80), started to receive care ≥1 year after diagnosis (HR=2.02, 95%CI: 1.30-3.15), their CD(4) cell count less than 200 cells/μl (HR=3.41, 95%CI: 2.59-4.59) at the time of diagnosis, with NVP in antiviral treatment (ART) regime (HR=1.36, 95%CI: 1.03-1.88), at Ⅲ/Ⅳ clinical stages (HR=2.61, 95%CI: 1.94-3.53) and CD(4) cell count less than 350 cells/μl (HR=5.48,95%CI: 2.32-12.72) at initiation of HAART ect., were more likely to die of AIDS-associated diseases. Conclusions: With the existence of competing risks, the cumulative incidence rate for AIDS-related death was overestimated by K-M, suggesting that competing risk models should be used in the survival analysis. Measures as early diagnoses followed by timely care and early HAART could end up with the reduction of AIDS-related death.

Abstract
Segmental defects are formidable challenges for orthopedic surgeons that are caused by large osseous defects such as open injury, comminuted fracture as well as other severe traumas and infection. Current treatment options have practical and clinical shortcomings, calling for innovative bone graft materials. This study is related to hollow tubular magnesium‑strontium (MgSr) alloy scaffolds with autologous morselized bone filled inside and three different coatings were individually applied on MgSr scaffolds, respectively, to study the effects of degradation and bioactivity of the grafts on new bone growth. The optimal coating method was screened using immersion tests, cell proliferation and adhesion, alkaline phosphatase (ALP) assay in vitro, and 4 weeks' implantation in a critical-size segmental defect in vivo. More new bone formation was observed by radiographic tests and histology along the ulna defects, when magnesium scaffold grafts were implanted. Meanwhile, depression occurred for blank control group with only autologous morselized bone filled, because of rapid absorption rate of morselized bone during initial implantation. Therefore, biodegradable MgSr alloy grafts showed their potential application in treating the critical-size segmental defects. As for different coating methods, CaP chemically deposited (CaP) coated sample showed least H2 evolution in vivo, demonstrating highest corrosion resistance and relative stable interfaces, however, the least beneficial ion release meanwhile. Micro-arc oxidation coating (MAO) degraded faster comparing with CaP, while with the main composition of MgO. They both indicate insufficient bioactivity in bone formation. The results suggest superior combination of bioactive surface, beneficial ions release and appropriate corrosion rate of Strontium phosphate conversion (SrP) coating, indicating superior comprehensive oeteoconductive and osteoinductive properties of coatings on hollow tubular MgSr alloy scaffold.

Abstract
Objective: To investigate the value of computed tomography (CT) texture analysis in differential diagnosis of inflammatory and malignant pulmonary nodules. Methods: The image data of 54 patients with lung cancer and 36 patients with pulmonary inflammatory nodules were retrospectively collected in our hospital. All the patients received chest CT scan. CT texture analysis of entropy, correlation degree and contrast ratio were performed by the MaZda software. The receiver operating characteristic curve (ROC) was established and the area under the curve (AUC) was calculated to evaluate the value of CT texture analysis in differential diagnosis of inflammatory and malignant pulmonary nodules. Results: In the lung cancer group, the value of entropy, correlation degree and contrast ratio were 1.58±0.07, 0.02±0.17 and 8.79±2.59, respectively. In the inflammatory nodules group, the value of entropy, correlation degree and contrast ratio were 1.51±0.04, 0.22±0.16 and 12.53±2.24, respectively. The differences were all statistically significant (P values were 0.008, 0.027, and 0.006, respectively) between two groups. There was not statistically significant difference (P>0.05) in the CT values between the lung cancer group and the inflammatory nodule group based on the non-contrast enhanced CT scan. Meanwhile, there was no statistically significant difference (P>0.05) in the value of entropy, correlation degree or contrast ratio between two groups based on arterial phase or venous phase of contrast enhanced CT. The ROC analysis showed that the AUC in differentiating the lung cancer and inflammatory nodules was 0.821, 0.778 and 0.875, respectively. The AUC of combination of three phases was 0.931, which was higher than the AUC of entropy, correlation degree and contrast ratio respectively (P<0.01). The sensitivity was 88.9%, and the specificity was 87.5%. Conclusion: CT texture analysis is a high-potential image analysis method, which can provide more information for the differential diagnosis of benign and malignant pulmonary nodules.

Why hasn't this woman been screened for breast and cervical cancer? - Evidence from a Chinese population-based study. Public Health 2019; 168:83-91. [PMID: 30708199 DOI: 10.1016/j.puhe.2018.12.007] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2018] [Revised: 12/01/2018] [Accepted: 12/10/2018] [Indexed: 11/16/2022]
Abstract
OBJECTIVE Less than half of eligible Chinese rural women have been screened for breast and cervical cancer. The objective of this study was to describe individual-level reasons for attending or not attending 'two cancers' screening using Andersen's Behavioral Model of Health Services Use. STUDY DESIGN Cross-sectional study. METHODS The study sample was from the Health Services Survey in 2013 in Jiangsu, China. A total of 6520 rural women aged 36-65 years answered the questions on 'two cancers' screening participation and were included in the final analysis, which consisted of univariate and multivariate logistic regression. RESULTS In the results of multivariate logistic regression, factors significantly associated with having 'two cancers' screening included educational level (odds ratio [OR] = 0.78, 95% confidence interval [CI] = 0.65-0.92), per capita household income (OR = 0.65, 95% CI = 0.58-0.73), availability of female medical faculty in township facilities (OR = 0.35, 95% CI = 0.28-0.42), quality of life (OR = 0.72, 95% CI = 0.58-0.90), being nulliparous (OR = 3.21, 95% CI = 1.96-5.26), and multiparous (OR = 1.91, 95% CI = 1.68-2.16). CONCLUSION To reduce inadequate screening service utilization of breast and cervical cancer in rural areas, efforts should be made not only to target the vulnerable rural women with lower income, lower educational level, and lower health conditions but also to further improve access to female primary-care providers. Strategies are also urgently needed to focus on nulliparous and multiparous women.

Abstract
Objective: To investigate the clinicopathological and ultrastructural characteristics of Langerhans cell histiocytosis (LCH) in children. Methods: A total of 345 cases of LCH from the Department of Pathology, Beijing Children Hospital from January 2012 to March 2016 were investigated by hematoxylin-eosin stain, EnVision immunohistochemistry and transmission electron microscopy. Results: The rate of primary clinical diagnosis of LCH in children was 46.0%(210/457). Among 345 patients of LCH, 213 were male and 132 were female, the male to female ratio was 1.6∶1.0, and the median age was 21 months (range from 2 days after birth to 13.3 years). There were total 597 lesions, including bony lesions (258, 43.2%), skin lesions (206, 34.5%) , followed by lymph node (16, 2.7%), lung (28, 4.7%), liver (25, 4.2%) and head-neck (50, 8.4%). Single organ system LCH (SS-LCH) was seen in 295 cases (85.5%) and 50 cases (14.5%) presented with multiple organ system involvement LCH (MS-LCH). There was no significant difference in age and gender between SS-LCH and MS-LCH groups. Regarding sites, more lesions were seen in bone and skin in SS-LCH group, in contrast lymph node, lung, liver and head-neck involvements were often seen in MS-LCH group. Immunohistochemically, the expression of CD1a and Langerin was seen in 99.7% (341/342) and 98.8% (338/342) of the cases respectively. The diagnostic rates by light and transmission electron microscopy were 98.8% (341/345) and 97.4% (112/115) respectively (P>0.05). Conclusions: LCH of children occurs predominantly in SS-LCH pattern, frequently involving bone, skin, lymph node, lung and liver and other sites with unique histopathological, immunophenotypical and ultrastructural features. Accurate diagnosis relies on the morphology, immunophenotype and ultrastructural features. Further refinement of specimen processing may improve the accuracy of pathological diagnosis.

Abstract
BACKGROUND Mucin over-secretion is a significant characteristic of chronic rhinosinusitis with nasal polyps (CRSwNP). This study aimed to investigate the relationship between Th2 cytokines and MUC5AC or MUC5B, and the mechanism of mucin over-secretion in the type-2 inflammatory endotype of CRSwNP. METHODS Main Th-cell cytokines, associated mediators, and mucins were determined in the homogenates of nasal polyp samples from 21 CRSwNP patients and inferior turbinate samples from 8 controls, by ELISA or UniCAP system. Secretion of MUC5AC and MUC5B was measured in the supernatants of IL-5, IL-4, or IL-13 primed nasal polyp fragments. Co-localization of MUC5AC, MUC5B, and IL-4 receptor α (IL-4Rα) in CRSwNP and controls was evaluated by immunohistochemistry. Gene expression of IL-4Rα in the samples was measured by real-time reverse transcription-polymerase chain reaction. RESULTS Baseline protein levels of the Th2-cytokines IL-4, IL-5, and IL-13, and mucins MUC5AC and MUC5B were significantly higher in the IL-5(+) CRSwNP group, compared to control and IL-5(-) CRSwNP groups. MUC5AC and MUC5B secretions were significantly increased in IL-4- or IL-13-primed, but not IL-5-primed fragments of nasal polyps. Immuno-stained serial sections demonstrated that IL-4Rα was widely expressed in the epithelium and submucosal glands in control and nasal polyp tissues. Gene expression of IL-4Rα was elevated in nasal polyp tissues, specifically in the IL-5(+) CRSwNP group. CONCLUSIONS In type-2 inflammatory nasal polyps, characterized by the tissue expression of IL-5, MUC5AC and MUC5B are overexpressed. Both IL-4 and IL-13 may upregulate mucin expression via IL-4Rα, which is also overexpressed in IL-5(+) CRSwNP.

Abstract
Objective: To summarize the clinical manifestations, pathological features, diagnosis, and treatment of abdominal solitary fibrous tumor (SFT). Methods: The data of clinical manifestations, pathological features, diagnosis, and treatment of 18 patients with abdominal SFT admitted to Department of General Surgery, Peking Union Medical College Hospital between January 2000 and December 2016 were retrospectively reviewed. Results: Abdominal mass was first presented in 14 patients. The blood routine, liver, kidney, and coagulation function were normal in all the patients. Tumor markers were abnormal in 4 cases. Most SFT showed hypoechoic mass with regular shape under ultrasound. CT findings differed among the cases. All the 18 patients underwent surgical treatment, and the diagnosis was proved by the postoperative histopathology. SFT differed in general morphology. The positive rate of Ki-67, smooth muscle actin (SMA), CD34, and S-100 was high under immunohistochemistry. Conclusions: Early diagnosis of abdominal SFT is difficult, leading to a low preoperative diagnosis rate. Complete removal of the tumor is the only reliable method of radical treatment.

Abstract
Perinatal depression affects 10-20% of women and is associated with poor outcomes for mother and child. Inflammation is associated with depression in non-pregnant adults. Perinatal depression and inflammation in pregnancy are independently associated with morbidities including obesity, gestational diabetes, preeclampsia, and preterm birth. The role of inflammation in perinatal depression has received little attention. We hypothesized an association between self-reported perinatal depressive symptoms and serum inflammatory biomarkers TNF-α, IL-6, IL-1β, and CRP. 110 healthy gravidas were recruited in third trimester from an academic medical center, with a baseline study visit at a mean of 32.5 (SD ± 1.8) weeks gestational age. Sixty-three participants completed the Edinburgh Postnatal Depression Scale (EPDS) and provided demographic information and serum samples upon enrollment and at 3 and 6 months postpartum. Serum inflammatory markers were quantified by multiplex array. Multiple linear mixed effects models were used to evaluate trends of biomarkers with the EPDS score in the third trimester of pregnancy and the postpartum period. Elevated serum TNF-α was associated with lower EPDS total score (β = - 0.90, p = 0.046) after adjusting for demographics and medication use. In contrast, IL-6, CRP, and IL-1β did not demonstrate statistically significant associations with depressive symptoms by the EPDS in either crude or adjusted models. Study findings showed no association or an inverse (TNF-α) association between inflammatory markers and perinatal depressive symptoms. Relevant literature evaluating a role for inflammation in depression in the unique context of pregnancy is both limited and inconsistent, and further exploration is merited.

Abstract
Objective: To explore the advantage of radiofrequency catheter ablation under the three-dimensional mapping in the treatment of atrioventricular nodal reentrant tachycardia (AVNRT) in reducing the X-ray exposure dose of interventional doctors. Methods: 79 patients with AVNRT, in the first hospital of Shanxi Medical University from January 2015 to June 2016, performed to do radiofrequency catheter ablation treatment were selected, and according to the random number method were divided into two-dimensional mapping group and three-dimensional mapping group. The two-dimensional mapping group was mapped the ablation target at the X-ray, while the ablation target was mapped by CARTO 3 system in the three-dimensional mapping group. Compare the X-ray fluoroscopy time, success rate, complications rate and doctor's X-ray exposure dose between the two groups. Results: Compared with the two-dimensional mapping group, acute success rate and complication rate of the three dimensional mapping group were not statistically significant (P>0.05) , while the X-ray fluoroscopy time and the X-ray dose of the three-dimensional mapping group decreased significantly, the difference was statistically significant (P<0.05) . Conclusion: Three-dimensional mapping can significantly reduce the X-ray irradiation time and interventional doctor's X-ray exposure dose in radiofrequency catheter ablation of AVNRT patients and the potential hazards of ionizing radiation on the human body.

Abstract
OBJECTIVES To evaluate the association of mannose-binding lectin (MBL) deficiency with susceptibility and clinical features of group B Streptococcus (GBS) causing meningitis in Chinese infants. METHODS During 2014-2017, 33 infants with laboratory-confirmed GBS meningitis were included. Six polymorphisms (H/L, Y/X, P/Q, A/D, A/B and A/C) of MBL were sought for in these patients and in 330 healthy controls by PCR-based sequencing. Serum MBL concentration was determined. RESULTS Significantly higher frequency of MBL variant genotype A/B was found in patients than controls (15/33, 45%, vs. 79/330, 24%, p=0.011). Patients with variant genotype A/B had significantly lower serum MBL than those with wild-type genotype A/A (median, 482.87 vs. 1455.13 ng/mL, p=0.002). Moreover, patients with genotype A/B had significantly higher level of C-reactive protein (median, 146 vs. 41 mg/L, p=0.007), neutrophil (median, 58.1% vs. 45.7%, p=0.033) and neutrophil-to-lymphocyte ratio in blood (median, 2.32 vs. 1.03, p=0.018) compared to those with genotype A/A. No significant differences were observed in clinical features of patients with different genotypes. CONCLUSIONS Our result suggested that infants with MBL deficiency are at higher risk of meningitis caused by GBS. Further studies in different populations with larger number of subjects are needed.
