Objective:To explore the molecular mechanism of Mimenghua Granules in treating dry eye based on network pharmacology and bioinformatics methods.Methods:Screening and prediction of possible blood-inducing active ingredients and action target of Mimenghua Granules through Traditional Chinese Medicine Systems Pharmacology database and analysis platform;mining dry eye-related diseases through disease gene database,gene target;use the functional protein combined network database STRING to draw the component-target and disease-target PPI networks,and extract the intersection of these two networks;use DAVID database analysis to screen key targets and analyze the mechanism of action.Results:A total of 593 active ingredients related to Mimenghua Granules were retrieved from the Traditional Chinese Medicine Systems Pharmacology database,and 59 blood active ingredients were obtained by screening based on pharmacokinetic parameters,and 680 targets related to these ingredients were retrieved;from disease genes,the database searches for 47 genes directly related to dry eye;3 key genes(ICAM1,IFNG,and IL-6)were obtained after the intersection of the component target and disease target PPI network;these genes are mainly involved in natural killer cell-mediated cytotoxicity,Jak-STAT signaling pathway,and Cytokine-cytokine receptor interaction.Conclusion:The mechanism of Mimenghua Granules in treating dry eye is related to the interaction of cytotoxic pathway,Jak-STAT signal pathway,and cytokines.The key gene targets are ICAM1,IFNG,and IL-6. 展开更多

Objective:The purpose of this study is to investigate the anti-diabetic effects of linarin,a flavonoid extracted from Chrysanthemi Indici Flos(CIF),and its potential mechanisms.Methods:The effects of linarin on cell viability and glucose consumption in Hep G2 cells were measured.Meanwhile,monosodium glutamate(MSG) mouse model was constructed to monitor the changes of insulin tolerance,glucose tolerance,triglyceride and cholesterol.The protein expression levels of pAMPK,p-ACC,PEPCK and p-GS were detected by Western blot.Results:Linarin could increase the relative glucose consumption of Hep G2 cells,improve insulin tolerance and glucose tolerance,and decrease the levels of triglyceride and cholesterol of MSG mice.Simultaneously,the expression levels of p-AMPK and p-ACC in Hep G2 cells and the liver tissue of MSG mice were increased,while the expression levels of PEPCK and p-GS were decreased after treatment with linarin.Conclusion:Insulin resistance could be ameliorated by linarin in type 2 diabetes,and its mechanism may be related to AMPK signaling pathway. 展开更多
