ABSTRACT OBJECTIVE To investigate the intervention effect and mechanism of Wuwei baogan pill on mice with non-
alcoholic fatty liver disease (NAFLD). METHODS The mice were given high-fat and high-sugar diet for 19 weeks to induce
NAFLD model. The model mice were randomly grouped into model group, positive control group (polyene phosphatidylcholine
capsules, 23.30 mg/kg), Wuwei baogan pill low-dose, medium-dose and high-dose groups (0.11, 0.23, 0.45 g/kg), with 8 mice
in each group; the normal group was additionally set up without modeling. Administration groups were given relevant medicine
intragastrically, and model group and normal group were given constant volume of normal saline, once a day, for consecutive 4
weeks. After the last administration, glucose metabolism (including fasting blood glucose, fasting insulin, insulin resistance
index), liver function [liver index, alanine aminotransferase (ALT), aspartate aminotransferase (AST),liver tissue pathological
score], lipid metabolism [triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-
density lipoprotein cholesterol (HDL-C)] were measured; the pathological morphology of liver tissue, as well as fibrosis, lipid
droplet formation, and glycogen synthesis were observed; the levels of free fatty acid (FFA) in serum and inflammatory factors in
liver tissue [tumor necrosis factor- α (TNF- α), interleukin-6
