The linearity of paeoniflorin was good in the range of 0.044 2～ 0.353 6 ? g(r=0.999 9)The average recovery of paeoniflorin was 97.56 % with RSD=1.18 % . Conclusion The established method is simple, feasible and repeatable, and can be used for the quality supervisory of Chanhoukang Granules.

Objective To investigate the efficacy and safety of citrate anticoagulation for continuous renal placement therapy (CRRT) in patients at high risk of bleeding. Methods Forty-seven patients who needed to CRRT and were admitted into the department of critical care medicine from January 2015 to October 2016 were enrolled in this study. According to the patient′s actual condition, they were divided into citrate groups (24 cases) and saline group (23 cases). Patients in saline group were given saline wash. The efficacy and safety were compared between the two groups. The filter lifetime, after treatment the activated partial thromboplastin time (APTT), hemoglobin (Hb), blood gas indexes were compared between the two groups. Results The citrate group used 76 filters while the 0.9% sodium chloride group used 87 filters. The average filter lifetime in citrate group was (22.4 ± 12.7) h which was longer than (8.6±3.3) h in 0.9%sodium chloride group (t=9.79, P<0.01). The incidence of coagulation in extracorporeal circulation was 3.9%(3/76) which was lower than 16.1%(14/87) in 0.9%sodium chloride group(χ2=5.20, P<0.05). Conclusions Regional citrate anticoagulation is a safe and effective option for CRRT in patients at high risk of bleeding.

Objective:Non-alcoholic fatty liver disease(NAFLD)has significant genetic susceptibility.Adipocytokines play a crucial role in NAFLD development by participating in insulin resistance and hepatic steatosis.However,the association between adipocytokine pathway genes and NAFLD remains unclear.This study aims to explore the association of gene polymorphisms in the adipocytokine pathway and their interactions with NAFLD in obese children. Methods:A case-control study was conducted,dividing obese children into NAFLD and control groups.Peripheral venous blood(2 mL)was collected from each participant for DNA extraction.A total of 14 single nucleotide polymorphisms(SNP)in the adipocytokine pathway were genotyped using multiplex PCR and high-throughput sequencing.Univariate and multivariate Logistic regression analyses were used to assess the association between SNP and NAFLD in obese children.Dominant models were used to analyze additive and multiplicative interactions via crossover analysis and Logistic regression.Generalized multifactor dimensionality reduction(GMDR)was used to detect gene-gene interactions among the 14 SNPs and their association with NAFLD in obese children. Results:A total of 1 022 children were included,with 511 in the NAFLD group and 511 in the control group.After adjusting for age,gender,and BMI,multivariate Logistic regression showed that PPARG rs1801282 was associated with NAFLD in the obese children in 3 genetic models:heterozygote model(CG vs CC,OR=0.58,95%CI 0.36 to 0.95,P=0.029),dominant model(GG+CG vs CC,OR=0.62,95%CI 0.38 to 1.00,P=0.049),and overdominant model(CC+GG vs CG,OR=1.72,95%CI 1.06 to 2.80,P=0.028).PRKAG2 rs12703159 was associated with NAFLD in 4 genetic models:heterozygous model(CT vs CC,OR=1.51,95%CI 1.10 to 2.07,P=0.011),dominant model(CT+TT vs CC,OR=1.50,95%CI 1.10 to 2.03,P=0.010),overdominant model(CC+TT vs CT,OR=0.67,95%CI 0.49 to 0.92,P=0.012),and additive model(CC vs CT vs TT,OR=1.40,95%CI 1.07 to 1.83,P=0.015).No significant multiplicative or additive interaction between PPARG rs1801282 and PRKAG2 rs12703159 was found in association with NAFLD.GMDR analysis,adjusted for age,gender,and BMI,revealed no statistically significant interactions among the 14 SNPs(all P>0.05). Conclusion:Mutations in PPARG rs1801282 and PRKAG2 rs12703159 are associated with NAFLD in obese children.However,no gene-gene interactions among the SNP are found to be associated with NAFLD in obese children.

To develop a quality control checklist for the prevention and control of coronavirus disease 2019 （COVID-19） in fever clinic and isolation ward of the general hospital and to assess its application. Based on the relevant prevention and control plans and technical guidelines for COVID-19，Delphi method was used to identity items for evaluation，and a quality control checklist for the prevention and control of COVID-19 in the fever clinic and isolation ward was developed in Sir Run Run Shaw Hospital. The checklists included 8 dimensions and 32 items for fever clinic，7 dimensions and 27 items for the isolation ward. The appointed inspectors conducted daily quality control for each shift with this checklist. The expert authority coefficient was 0.88，the mean of the importance of each index in the quality control table was not less than 4.8，and the coefficient of variation was not more than 0.07. During the entire February 2020，8 problems were found and rectified on-the-spot with the application of the checklist. Quality inspection rate was 100% in both isolation wards and fever clinic. The compliance rate and accuracy rate of hand hygiene were 100%; the correct rate of wearing and removing protective equipment increased from 96% to 100%. During the same period，a total of 1915 patients were admitted to the fever clinic，including 191 suspected patients （all were isolated in the hospital，3 were confirmed）. There were no medical staff infected with COVID-19，no cross infection of patients and their families in the hospital. A quality control checklist for the prevention and control of COVID-19 has been developed and applied in the isolation wards and fever clinic，which plays an important role in preventing nosocomial infection.
