Objective To study how to use the machine of B.BRAUN's Diapact continuous renal replacement therapy (CRRT) to achieve multiple models of plasma treatment by analyzing the characteristics of the machine.Methods Based on the machine of B.BRAUN's Diapact CRRT,assisted by extra single pump,the pipeline connection of the machine was reformed and the appropriate parameter was reset.Results After the reconstruction,the new equipment could succeed in achieving special plasma treatment such as double filtration plasmpheresis (DFPP)and plasma adsorption (PA).Conclusions The reconstructed equipment can attain special plasma treatment.Compared with plasma exchange (PE),the equipment has some characteristics such as few syndromes and without external plasma.According to its safety and stability,this new method is suitable for clinical application.

Methanol fuel is a most promising substitute for gasoline. It is scarcely reported about methanol-fueled exhaust on the health effect, neither about genotoxicity research between methanol- and gasoline-fueled exhaust. In the present study, the two kinds of exhaust were sampled directly from tailpipe at the same type bus, the same state, L5178Y thymidine kinase (TK) gene mutation assay was used to investigate their genotoxicity at the same dose range, and compared with micronucleus and comet assay. The results showed that the genotoxicity of gasoline-fueled exhaust is stronger than that of methanol-fueled exhaust, while the cytotoxicity of methanol-fueled exhaust is stronger than that of gasoline-fueled exhaust at dose range. The study demonstrated that L5178Y TK gene mutation assay is more sensitive than micronucleus and comet assay.

Objective:To analyze the application value of non-invasive inflammation diagnosis model in the diagnosis of liver fibrosis in patients with non-alcoholic fatty liver disease (NAFLD) combined with hepatitis B virus (HBV) infection.Methods:A total of 98 patients with NAFLD complicated with HBV infection admitted to some coastal China Coast Guard Hospital of People′s Armed Police from June 2019 to October 2021 were selected. Their liver stiffness (LSM), aspartate aminotransferase to platelet ratio (APRI), γ-glutamyltranspeptidase to platelet ratio (GPR), and fibrosis index based on factor 4 (FIB-4) were measured, The receiver operating characteristic (ROC) curve was used to analyze its clinical diagnostic efficacy for liver fibrosis caused by NAFLD combined with HBV infection.Results:Among 98 patients, there were 7 cases in S0 stage, 47 cases in S1 stage, 21 cases in S2 stage, 14 cases in S3 stage, and 9 cases in S4 stage; Including 35 cases of obvious liver fibrosis and 9 cases of cirrhosis. There was no statistically significant difference in gender and body mass index (BMI) among patients in different stages (all P>0.05). Age: the S0 group
