ABSTRACT
Nonalcoholic fatty liver disease (NAFLD) is a type of metabolic disorder syndrome of abnormal lipid deposition in hepatocytes, and with the improvement of living standards, the incidence rate of NAFLD has reached a worrying level. Several anthropometric indicators, including waist circumference, waist-hip ratio, and waist-height ratio, have been used in the evaluation of obesity and the correlation study of various metabolic diseases. This article introduces the association between NAFLD and various anthropometric indicators for obesity and points out that anthropometric indicators for obesity can be used for the prevention and control of NAFLD.

ABSTRACT
ObjectiveTo investigate the expression and clinical significance of OX40/OX40L (CD134/CD134L) in CD4+ T cells, CD8+ T cells, monocytes, and B lymphocytes in peripheral blood of patients with autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and their overlap syndrome before and after standardized treatment. MethodsA total of 74 patients with AIH, PBC, and their overlap syndrome who were diagnosed in Subei People’s Hospital of Jiangsu from August 2015 to August 2019 were enrolled, and according to related diagnostic criteria, they were divided into AIH group (group A) with 29 patients, PBC group (group P) with 26 patients, and overlap syndrome group (group C) with 19 patients. A healthy control group with 30 individuals was also established. Peripheral blood samples were collected before and after standardized treatment to measure the expression of OX40/OX40L on the surface of peripheral blood cells by immunofluorescence flow cytometry, and the expression of OX40/OX40L was compared before and after treatment and between the three groups and the healthy control group to investigate its clinical significance. A one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test was used for further comparison between two groups; the paired t-test was used for comparison of paired samples between two groups. ResultsThere were no significant differences in sex composition and age composition between the three groups (P＞0.05). Before treatment, the positive rate of OX40 in peripheral blood CD4+ T cells gradually increased in groups A, P, and C, and groups A, P, and C had a significantly higher positive rate of OX40 than the control group (14.80%±4.99%/17.11%±2.71%/25.18%±5.55% vs 6.67%±2.26%, F=14.823, P＜0.001); groups A, P, and C had a significantly higher positive rate of OX40 in CD8+ T cells than the control group (4.86%±1.54%/6.40%±1.88%/7.33%±2.12% vs 4.09%±2.69%, F=5.486, P＜0.001); the positive rate of OX40L in CD14+ monocytes was 19.84%±6.11% in group A, 21.17%±4.35% in group P, 29.13%±6.32% in group C, and 4.86%±2.34% in the control group, and there was a significant difference between groups (F=17004, P＜0.001); the positive rate of OX40L in CD19+ B cells was 17.62%±3.86% in group A, 14.75%±4.32% in group P, 1013%±2.56% in group C, and 4.50%±1.38% in the control group, showing a trend of gradual reduction, and groups A, P, and C had a significantly higher positive rate than the control group (F=12.221, P＜0.001). After treatment, the positive rate of OX40 in CD8+ T cells decreased significantly to a similar level as the control group, and there was no significant difference between groups (F=0731, P=0.538). For the other three types of cells, although there were varying degrees of reduction in the positive rate of OX40/OX40L after treatment, groups A, P, and C still had a significantly higher positive rate than the control group; in CD4+ T cells, the positive rate of OX40 was 11.00%±1.98% in group A, 13.72%±1.03% in group P, 19.72%±3.47% in group C, and 6.67%±2.26% in the control group, and groups A, P, and C had a significantly higher positive rate than the control group (F=11.365, P＜0.001); in CD14+ monocytes, the positive rate of OX40L was 11.82%±2.23% in group A, 15.19%±4.42% in group P, 24.51%±4.09% in group C, and 4.86%±2.34% in the control group, and groups A, P, and C had a significantly higher positive rate than the control group (F=13748, P＜0.001); in CD19+ B cells, the positive rate of OX40L was 9.09%±3.25% in group A, 6.81%±2.20% in group P, 748%±2.85% in group C, and 4.50%±1.38% in the control group, and groups A, P, and C had a significantly higher positive rate than the control group (F=8.052, P＜0.001). Groups A, P, and C had significant reductions in the expression of OX40/OX40L in peripheral blood CD4+ T cells, CD8+ T cells, CD14+ monocytes, and CD19+ B lymphocytes after treatment (all P＜0.05). ConclusionThe expression of OX40/OX40L in peripheral blood increases in patients with AIH, PBC, and their overlap syndrome and decreases after treatment, indicating that the OX40/OX40L pathway is involved in the pathogenesis of the above diseases, and the role of OX40 on the surface of CD8+ T cells may better reflect the treatment outcome.
ABSTRACT
Objective: To introduce the construction idea and function for establishing China Cardiovascular Surgery Registry (CCSR)database and to provide a reference for domestic congener databases. Methods: Using peer database as reference, taking current status of cardiovascular surgery registry and hardware in our country with the necessity of international communication, we worked on a variables selection, metadata instruction, logic rules, case report form develpment and finally established a web-based, multi-functional database that enabled cross-database and international merging of data, forming a national intelligent data-exchanging platform for cardiovascular surgery. Results:CCSR database has over 300 variables of multiple topics including basic information, risk factors, medical procedures and endpoint events. Taking clinical and association data exchange standards as reference, it may conduct cross-discipline data connection, record important peri-operative information in relevant patients and meanwhile, it has the functions of automatic logic check, data report, statistical study, data export and importing the electronic medical records. Conclusion:CCSR database is a national platform accord with current status of Chinese cardiovascular surgery and characteristics, meanwhile it gives consideration to international communication and data exchange; which may play a important role in improving medical care and clinical investigation.

ABSTRACT
OBJECTIVE:To analyze the dyeing status of cinnabar and its pieces,and provide reference for its quality clinical safetey appicaton. METHODS:TLC was used for the qualitative identification of amaranth,carmine,erythrosine,acid red 73, 808 udan and indirubin. HPLC-MS was used to detect the 808 udan :HPLC conditions were as follows,column was Acquity UPLC BEH C18 with mobile phase of cetonitrile-0.1% formic acid(70∶30,V/V)at a flow rate of 0.3 ml/min,the detection wave-length was 520 nm;MS conditions were as follows,ion source was electrospray ionization source,scanning mode was positive ion scanning with full scanning tandem mass spectrometry,nebulizer pressure was 30 psi,drying gas was nitrogen,ion spray voltage was 4 000 V,collision energy was 30 V,and the injection volume was 5 μl. The volumetric method was used for content determi-nation of HgS. RESULTS:TLC spots of amaranth,carmine,erythrosine,acid red 73,808 udan and indirubin were clear and well-separated. 4 batches of 808 udan dyeing were included in the 18 batches of samples,6 batches had non-compliance contents (including 3 batches of 808 udan dyeing). CONCLUSIONS:Dyeing-doped and other quality problems exist in the cinnabaris in markets,which should be noticed.
