Objective:To analyze the expression of tumor-associated transmembrane protein 61 (TMEM61) in cholangiocarcinoma tissues and its influence on prognosis and immune infiltration, as well as the effect on the proliferation of cholangiocarcinoma cells.Methods:In the cholangiocarcinoma gene chip dataset (TCGA-CHOL), differentially expressed genes between cholangiocarcinoma tissues and normal bile duct tissues were screened, and the upregulated TMEM61 gene was selected for further analysis. Based on the TMEM61 expression, cholangiocarcinoma patients higher than the median value were classified as the high-expression group ( n=17), and those lower than the median value were classified as the low-expression group ( n=18). The Kaplan-Meier survival curve was plotted. Functional and pathway enrichment analyses were conducted on differentially expressed genes related to TMEM61, and the correlations between TMEM61 expression and immune cells and immune molecules were respectively analyzed. The expression level of TMEM61 in cholangiocarcinoma tissues was analyzed by immunohistochemistry; The effect of TMEM61 expression on the proliferation of cholangiocarcinoma cells was detected by Western blotting, CCK-8, clone formation assay, etc. Results:Compared with normal tissues, the expression of TMEM61 mRNA in cholangiocarcinoma tissues was significantly upregulated ( t=18.31, P<0.001). The overall survival rate of patients in the high-expression group of TMEM61 was significantly lower than that in the low-expression group, and the difference was statistically significant ( χ2=7.23, P=0.007). The differentially expressed genes related to TMEM61 were involved in cell proliferation, cell cycle and DNA replication, etc. Compared with normal tissues, regulatory T cells ( t=10.21, P<0.001) and M0-type macrophages ( t=5.89, P=0.008) were significantly increased in cholangiocarcinoma tissues. Plasma cells ( t=7.34, P=0.002), γδT cells ( t=9.87, P<0.001), and M2-type macrophages ( t=11.53, P<0.001) were significantly decreased in cholangiocarcinoma tissues. The expression of TMEM61 was correlated with neurociliary protein 1, tumor necrosis factor ligand superfamily member 15 and B7 homologous protein 3 (all P<0.05). The proportion of positive staining area of TMEM61 protein in normal tissues was (10.15±2.27) %, and that in cholangiocarcinoma tissues was (69.43±11.66) %. The difference was statistically significant ( t=14.97, P<0.001). Inhibition of TMEM61 expression led to a decrease in the number of cholangiocarcinoma cell clones and proliferation activity, and the differences were statistically significant (both P<0.01). Conclusion:The expression of TMEM61 is elevated in cholangiocarcinoma tissues and is associated with poor prognosis. The abnormally high expression of TMEM61 affects the infiltration of immune cells and promotes the proliferation of cholangiocarcinoma cells. TMEM61 is expected to become a potential biomarker for the prognosis assessment of cholangiocarcinoma.

Objective To investigate the effects of scribble planar cell polarity protein(SCRIB)on proliferation,apoptosis,and autophagy of glioblastoma(GBM)and elucidate its potential underlying mechanisms.Methods The expression level of SCRIB in GBM tissue was queried through the Biomarker Exploration of Solid Tumors(BEST)database.Lentivirus-mediated shRNA interference was employed to downregulate SCRIB expression in human glioblastoma cell lines U87 and U251,which were divided into negative control group(mock)and SCRIB shRNA interference groups(kd1 and kd2).SCRIB expression levels were detected using Western blotting(WB)and quantitative polymerase chain reaction(qPCR).EdU incorporation and cell apoptosis rates were detected by flow cytometry(FCM).CCK-8 assay was used to detect the proliferation vitality of U87 and U251 cells,and WB was used to detect the expression of proliferation-related proteins.Immunofluorescence(IF)staining was conducted to detect the expression of autophagy-related proteins LC3 and p62,followed by quantitative analysis across multiple fields.WB was also used to detect the expression levels of LC3,p62,and proteins in the JAK-STAT3 signaling pathway.Results Compared with that of normal tissues,SCRIB mRNA expression level was significantly upregulated in GBM tissues(P＜0.05).FCM results showed that EdU incorporation rates were significantly reduced(P＜0.001)while cell apoptosis rates were markedly increased(P＜0.001)in U87 and U251 cells with SCRIB knockdown.CCK-8 results indicated that compared with the mock group,the proliferation vitality of U87 and U251 cells in the SCRIB knockdown group was significantly downregulated(P＜0.001).IF staining showed that LC3 fluorescence aggregation was significantly enhanced(P＜0.001),while p62 fluorescence aggregation was significantly reduced(P＜0.001)in the SCRIB knockdown group.WB results showed that compared with the mock group,the protein expression levels of p27,LC3,p-JAK2 and p-STAT3 were upregulated,while C-Myc,Cyclin D1,MCM,PCNA and p62 were downregulated,with statistically significant differences(P＜0.05).Conclusion Downregulation of SCRIB may induce autophagy and apoptosis in glioblastoma cells by inhibiting the JAK-STAT3 signaling pathway,thereby suppressing cell proliferation.

Objective: To investigate the prevalence of dyslipidemia among adults in Moyu County, Hotan Prefecture, Xinjiang Uygur Autonomous Region, so as to provide insights into the management of dyslipidemia. Methods: The physical examination data of permanent residents at ages of 18 years and older were collected from Moyu County from 2018 to 2019, including demographic features, height, body weight, blood pressure and blood biochemical parameter measurements. The epidemiological characteristics of dyslipidemia were analyzed among residents. Results: Totally 166 142 adults were investigated, with a mean age of (41.08±15.72) years. There were 77 744 men (46.76%), 34 728 obese adults (20.90%), 5 776 adults with diabetes (3.48%) and 26 294 adults with hypertension (15.83%). The levels of triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were (1.38±0.98), (4.13±1.19), (1.31±0.41) and (2.25±0.77) mmol/L, respectively. The prevalence of dyslipidemia was 29.72%, and the detection rates of high TG, high TC, low-HDL-C and high LDL-C were 9.73%, 4.59%, 19.65% and 1.99%, respectively. The prevalence of dyslipidemia was higher in men than in women (33.97% vs. 25.98%; χ2=1 264.729, P<0.001), and the prevalence increased with age (χ2=539.382, P<0.001) and body mass index (χ2=3 601.833, P<0.001). The prevalence of dyslipidemia was 35.48% among patients with hypertension (χ2=497.251, P<0.001) and 46.07% among patients with diabetes (χ2=766.142, P<0.001). There were 9 059 adults with two and more abnormal blood lipid indexes (18.35%), and the detection rates of two and more abnormal blood lipid indexes were 26.50%, 24.14% and 33.15% among patients with obesity, hypertension and diabetes, respectively. Conclusions The prevalence of dyslipidemia among adults in Moyu County is lower than the national level, and low-HDL cholesterolemia is the most common type of dyslipidemia. The prevalence of dyslipidemia is high among patients with obesity, hypertension and diabetes mellitus, in whom abnormality of multiple blood lipid indexes is measured.

Objective To explore the prevalence and characteristic of Non-alcoholic fatty liver disease (NAFLD) among the ethnic Kirghiz adult in Xinjiang Province. Methods The study was conducted based on the national health checkup in Xinjiang province during 2018. A total of 19 843 participants of Kirghiz adults in Aheqi County, Xinjiang Uygor Autonomous Region were selected for physical examination, questionnaires, blood biochemical indicators detection (FBG, TG, LDL-C, HDL-C, TC, ALT and AST) and abdominal ultrasonography. A total of 1 396 patients diagnosed with NAFLD by abdominal ultrasonography were selected as the case group, and 4 188 non-NAFLD subjects matched in age, sex and region were selected as the control group at a ratio of 1:3. The clinical characters and risk factors of NAFLD patients were analyzed. Results The overall prevalence of NALFD in Kirghiz adults was 7.0%, 7.8% in male, and 6.2% in female (standardized to 6.8%, 7.5%, and 6.0%, respectively). The prevalence in male was higher than that in female (P<0.01). The prevalence of NAFLD in the obesity, diabetes, and hypertension group was significantly increased, which was 19.0%, 20.6% and 18.5%, respectively. Body mass index (BMI), waist circumference (WC), triglycerides, AST (aspartate aminotransferase) and ALT (alanine transamilase) in the NAFLD group were all higher than those in the control group (all P < 0.01). In the NAFLD group, 17.2% had another one metabolic disorder and 62.0% had another two metabolic disorders. Logistic regression analysis showed that waist circumference (OR = 4.08, 95%CI = 3.04~5.10), FBG (OR = 3.76, 95%CI = 2.86~4.93) and BMI (OR = 3.32, 95%CI = 2.16~4.38) were the main independent risk factors for NAFLD. Literacy (OR = 0.42, 95%CI = 0.24~0.69) and physical activity (OR = 0.68, 95%CI = 0.45~0.96) were protective factors. Conclusion The prevalence of NAFLD in Kirgiz adults in Xinjiang is lower than the national average. More than half of NAFLD patients are comorbidity with at least two metabolic abnormalities. WC, FBG and BMI were the independent risk factors for NAFLD, however, literacy and physical activity were protective factors.

Objective To discuss the anticoagulation effects and safety of sodium citrate in continuous renal replacement therapy (CRRT).Methods A total of 140 cases who underwent CRRT in the intensive care unit (ICU) of Zhejiang Provincial People′s Hospital from January 2014 to December 2016 were selected as research objects and divided into the heparin sodium group (n=56),the low molecular weight heparin calcium group (n=48) and the sodium citrate group (n=36) according to the anticoagulation methods. The differences of anticoagulation effects,the average service life of the pipelines,the overall pipeline quantity,the total cost of blood purification,the blood transfusion amount during CRRT,total bilirubin (Tbil),serum creatinine (Cer), Na+,K+,prothrombin time (PT),activated partial prothrombin time (APTT),platelet count (PLT) before and after CRRT and the complications related to CRRT among the three groups were compared.Results The anticoagulation effect of the sodium citrate group was obviously better than that of the other two groups (χ2=18.809,P<0.05). The average service life of the pipelines of the sodium citrate group was (29.3±5.4) h, which was obviously higher than that of the heparin sodium group (16.5±3.5) h and the low molecular weight heparin calcium group (24.8±4.1) h,and the intergroup difference was statistically significant (F=6.596, P<0.05). The transfusion amount of red blood cells,plasma and platelets of the sodium citrate group was (12.3±2.8) U,(1875.5±198.6) ml and (23.5±8.6) U,which was obviously lower than that of the heparin sodium group [(16.5±5.6) U,(2463.4±265.4) ml and (58.3±18.5) U] and the low molecular weight heparin calcium group [(13.4±3.2) U,(1954.4±214.5) ml and (32.6±11.5) U],and the intergroup differences were all statistically significant (F=4.563,3.896,7.456;P<0.05). The Tbil,Cer,Na+ and K+ of all groups decreased after CRRT,and the differences were all statistically significant (P<0.05). There were statistical significance in PT,APTT and PLT among the three groups (F=4.562,4.153,5.468;P<0.05). The PLT of the sodium citrate group increased significantly after CRRT,with statistical difference (P<0.05). The incidence rate of hemorrhages in skin,digestive tract,puncture point and trachea of the sodium citrate group was respectively 2.8％,5.6％,2.8％ and 5.6％,which was obviously lower than that of the heparin sodium group (23.2％,12.5％, 16.1％,12.5％) and the low molecular weight heparin calcium group (6.3％,10.4％,8.3％,8.3％),and the differences were all statistically significant (χ2=6.678,7.553,6.849,7.534;P<0.05). The incidence rate of heparin induced thrombocytopenia (HIT) of the heparin sodium group was 8.9％ (5/56).Conclusions The anticoagulation effect of sodium citrate in CRRT is remarkable with less complications. It can significantly reduce the amount of blood transfusion and the cost of blood purification and is worth of promotion in clinical application.

Objective To investigate the influence factors of temporary catheter obstruction after sealing in the CRRT.Methods A total of 811 patients undergoing the CRRT in ICU of our hospital from July 2015 to March 2016 were included in the study. Retrospective analysis was used to investigate the influence factors of CRRT temporary catheter obstruction.Results A number of 755 out of 811 patients were catheter unobstructed,while 56 cases (6.9%) had catheter obstruction. Single factor analysis showed that 5 factors including APTT,PLT,modes of anticoagulation,diabetes and anticoagulants,had statistically significant (t/χ2=5.133,6.092,53.548,10.646,4.765;P<0.05). Logistic multivariate linear regression analysis showed that PLT,history of diabetes,APTT and modes of anticoagulation were influence factors of catheter obstruction after sealing.Conclusions The main influences factors of the CRRT temporary catheter occlusion after sealing were PLT,diabetes,APTT and modes of anticoagulation. However,further multicenter study with large sample size is necessary.

Objective To evaluate systematic reviews or Meta-analyses related to ventilator-associated pneumonia (VAP) in closed suction system or open suction system.Methods CNKI, CBM, Cochrane Library, Web of Science, MEDLIN and Embase databases were searched for systematic reviews or meta-analyses in closed suction system and open suction system. Two reviewers independently evaluated the articles, and then extracted the data. QQAQ evaluation sheet was used to assess and cross-check reporting characteristics and methodological quality of included literature respectively, and divergence would be resolved by discussion. Results Nine systematic reviews or Meta-analysis were included, which involved three aspects: incidence rate of VAP, airway colonization bacteria and the duration of mechanical ventilation.Conclusions This revaluation of systemic evaluation provides high-quality evidence resources and provides reliable evidence support for the development of clinical practice.

Objective To explore the better lock solutions of temporary catheter for patients with cont inuous renal replacement therapy (CRRT) in intensive care unit. Methods A total of 235 patients with insertion of temporary central venous catheters were divided into two groups randomly. 500 U/ml heparin saline was used in the observational group (123 cases) and 1 000 U/ml heparin saline was used in the control group (112 cases). Two groups adopted positive pressure seal tube method, and the situation of catheters and bleeding were observed. Results There were no statistical significance of two groups in the situation of catheters and bleeding (P>0.05). Logistic regression:8 observational factors (machine type, dilution method, catheter placement, blood flow velocity, the use of anticoagulants, whether to use immunity inhibitors, whether for high blood pressure, diabetes) in the Logistic regression, no factors was found to have association with the situation of catheters (P>0.05 ), 2 factors were found to have association with bleeding (P<0.05 ), one hazard effect:the maximum flow of blood, one positive effect:the position of catheter. Multiple linear regression: 6 observational factors [hemoglobin, acute physiology and chronic health evaluation (APACHE)Ⅱ, C-reactive protein, systolic pressure, diastolic pressure, activated partial thromboplastin time (APTT)] in the multiple linear regression, two factors were found to have association with the situation of catheters (P>0.05 ), all of them had positive effect: APACHEⅡ,APTT; two factors were found to have association with bleeding (P < 0.05), all of them had hazard effect: APACHEⅡ,APTT. Conclusions Compared with 1 000 U/ml, 500 U/ml heparin lock solutions doesn′t increase the thrombosis of temporary catheters, and also decrease the rate of bleeding,so 500 U/ml heparin lock solutions can use in CRRT patients who use anticoagulant.
