Objective To compare the pharmacological actions of Liandai Tablet(LT) and its main active components on apoptosis of gastric cancer cells and DNA damage. Methods Effects of Liandai Tablet(LT) and its main active components,berberine and indirubin,on growth and apoptosis of gastric cancer cell strain MGC_803 were explored and their effects on DNA damage were also studied. Results LT serum in high and low dosages and berberine could inhibit the growth of MGC_803 as compared with the control group,and typical morphological features of apoptosis were found in the MGC_803 by methyl green pyronin stain assay.But indirubin at various concentrations showed no obvious inhibitory effects. Agarose gel electrophoresis assay revealed that the MGC_803 cell DNA was split into large fragments when treated with berberine. Conclusion LT serum exerts a similar inhibitory effect on the growth and apoptosis of gastric cancer cells as compared with berberine.The effects of LT at various serum concentrations on MGC_803 DNA was less than that of berberine,and indirubin at the given concentration had no this effect.

OBJECTIVETo establish an in vitro cell model for investigating hepatic steatosis in non-alcoholic fatty liver disease.

METHODSL-02 cells cultured in 1640 containing 10% fetal bovine serum were divided into control group and model group. At 70%-80% confluency, L-02 cells in the model group were exposed to a long-chain mixture of free fatty acids (FFA, oleate and palmitate ) for 24 h, and cells in control group were treated with fresh medium. Lipid droplets in the cells were observed and total lipid content was determined with Oil Red O staining. The morphology of lipid droplets, trilyceride level, malonaldehyde content and cell apoptosis rate were evaluated to verify the cell model, and the effect of Huganqingzhi tablet on the lipid droplets was observed.

RESULTSA large number of lipid droplets were found in the cell model, which showed markedly increased level of triglyceride without significant changes of malonadehyde content or cell apoptosis rate. Intervention with two doses of Huganqingzhi tablet significantly decreased the number of lipid droplets and trilyceride content in the cell model.

CONCLUSIONhepatic steatosis L-02 cell model can be established by long-chain mixture of free fatty acids (oleate:spalmitate=2:1) for therapeutic drug studies.

OBJECTIVE To provide reference for improving rational use of antibiotics in medical institutions. METHODS With the help of information construction， strengthening personnel training and assessment， carrying out science popularization and education， optimizing drug catalogs， equipping full-time clinical pharmacists， optimizing assessment indicators and releasing pharmaceutical information in time， new fine management mode of antibiotics was constructed in our hospital. Through the hospital information system， the relevant data of our hospital in Jan.-Dec. 2020 （before the implementation） and Jan.-Dec. 2021 （after the implementation） were collected and compared， such as utilization rate of antibiotics， intensity of antimicrobial use， the incidence of hospital infection in the inpatients， the incidence of surgical site infection， the qualified rate of antibiotic medical order， and the proportion of antibiotics in the total outbound amount of Western medicine. RESULTS Compared with 2020， the utilization rate of antibiotics in hospitalized patients in 2021 decreased from 34.94% to 32.44%， intensity of antimicrobial use decreased from 39.07 DDDs （defined daily doses） to 30.77 DDDs， and the incidence of nosocomial infections among inpatients decreased from 2.64% to 1.91%； the incidence of surgical site infections decreased from 0.26% to 0.03%； the qualified rate of antibiotic medical orders increased from 93.82% to 97.75%； the proportion of antibiotics in the total outbound amount of Western medicine decreased from 14.86% to 12.51%.CONCLUSIONS Through a series of fine management measures， our hospital has built a new fine management mode of antibiotics， which has improved the rationality of antibiotics use while ensuring the treatment effect.

OBJECTIVE To study the effects of isoliquiritigenin （ISL） regulating gut microbiota and repairing gut barrier function in model mice with non-alcoholic fatty liver disease （NAFLD）， and to clarify its mechanism for improving NAFLD. METHODS Thirty male C57BL/6J mice were randomly divided into the normal （ultrapure water）， model group （ultrapure water）， ISL group （100 mg/kg）， with 10 mice in each group. Model group and ISL group were fed with high-fat diet for 19 weeks to establish NAFLD model； at the same time， the mice were given relevant medicine/ultrapure water intragastrically. The changes of body weight in mice were recorded， and liver index， white fat index and brown fat index were calculated. The pathological changes of liver tissue and colon tissue as well as lipid accumulation were observed in mice. The levels of total cholesterol （TC）， triglyceride （TG）， aspartate aminotransferase （AST） and alanine aminotransferase （ALT） E-mail：xiangshj3@mail.sysu.edu.cn in serum or liver were measured； the serum levels of interleukin-6 （IL-6）， IL-1β and tumor necrosis factor-α （TNF-α） and the levels of IL-6， IL-1β and TNF-α mRNA expression in liver tissue were detected. Fecal samples underwent 16S rDNA sequencing analysis， and the effects of ISL on gut microbiota structure of mice were investigated. The expressions of gut mucosal barrier-related proteins （Claudin-4， Occludin and ZO-1） were determined in the colon tissue of mice. RESULTS Compared with model group， the body weight， liver index， the levels of TC in liver tissue and serum， the levels of AST and ALT in serum， the levels of IL-6， IL-1β and TNF-α in serum， and the mRNA expression of TNF-α in liver tissue were all decreased significantly in ISL group， while brown fat index was increased significantly. The inflammation and damage of liver tissue were significantly improved， and the NAFLD activity score and the proportion of lipid staining area were significantly reduced （P＜0.05）. ISL could significantly up-regulate the relative abundance of beneficial microbiota （norank_f_Muribaculaceae， Odoribacter， Ruminiclostridium， etc.） and the expressions of intestinal barrier function- related proteins， but could significantly down-regulate the relative abundance of harmful bacteria （Desulfovibrio， norank_f_Lachnospiraceae， unclassified_p_Firmicutes）， and could repair intestinal barrier. CONCLUSIONS ISL could significantly delay the progress of NAFLD， the mechanism of which may be associated with regulating gut microbiota and improving gut barrier function.

OBJECTIVE To study the effects of bergapten in the treatment of liver fibrosis and its mechanism based on serum metabolomics. METHODS Forty mice were divided into normal control group （0.5% carboxymethyl cellulose sodium solution）， model group （0.5% carboxymethyl cellulose sodium solution）， and BP low-dose and high-dose groups （50， 100 mg/kg）， with 10 mice in each group. Except for the normal control group， the other three groups were all treated with carbon tetrachloride to induce liver fibrosis model； they were given relevant medicine/solution intragastrically， once a day， for consecutive 8 weeks. After the last medication， the levels of alanine aminotransferase （ALT） and aspartate aminotransferase （AST） in serum were detected， and liver pathological changes were observed； the expressions of α-smooth muscle actin （α-SMA） and Collagen Ⅰ were detected in liver tissue； the serum of the mice was collected for metabolomics analysis. RESULTS Compared with the model group， serum levels of ALT and AST and protein expressions of α-SMA and Collagen Ⅰ in liver tissue were decreased significantly in BP high-dose and low-dose groups （P＜0.05）， while liver fibrosis was improved significantly. Meanwhile， metabolomics analyses showed that there were a total of 175 serum differential metabolites in the BP high-dose group and model group， of which 18 substances were upregulated and 157 substances were downregulated； the main metabolic pathways involved in bergapten intervention were pyrimidine metabolism， butanoate metabolism， fatty acid synthesis， tyrosine metabolism， β-alanine metabolism， nicotinic acid and nicotinamide metabolism， glutathione metabolism， etc. CONCLUSIONS BP is effective in the treatment of liver fibrosis by regulating pyrimidine metabolism， butanoate metabolism， glutathione metabolism and so on in rats with liver fibrosis.
