Serum metabolomics-based study on the mechanism of action of bergapten in the treatment of liver fibrosis / 中国药房

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.

Clinical effect observation of Iodized Lecithin Capsules in the treatment of vitreous hemorrhage / 中国基层医药

Objective To determine the clinical effect of Iodized Lecithin Capsules in the treatment of vitre-ous hemorrhage.Methods 102 patients ( 102 eyes ) with vitreous hemorrhage were divide into Group A ( treatment group) and Group B ( control group);the treatment for Group A with 52 patients (52 eyes) is taken Iodized Lecithin Capsules orally;for Group B with 50 patients (50 eyes),it was the prolonium iodide through intramuscular injection. The course of treatment for both Group A and B was 3 months and all the patients in the two groups receive systemic diseases treatment and etiological treatment at the same time.The clinical effects of both groups will be compared. Results The effective rate for Group A was 82.7% whereas the figure for Group B was 64.0%.The differences between the two groups had statistical significance(χ2 =4.58,P <0.05).Conclusion By taking Iodized Lecithin Capsules orally is a very effective way to treat vitreous hemorrhage without obvious side effects.The treatment is safe and effective.
