Methods: A rat model of non- alcoholic fatty liver disease was established after 20 weeks of high-fat feeding, and the rats were divided into six groups, normal group, model group, simvastatin group (4 mg/kg), low- dose group of Linggui Zhugan Decoction (2.1 g/kg), medium-dose group of Linggui Zhugan Decoction (4.2 g/kg), and high-dose group of Linggui Zhugan Decoction (8.4 g/kg), and the liver morphological changes of HE staining and oil red O staining after the intervention of Linggui Zhugan Decoction were observed, and the microplate reader detected aspartate aminotransferase, alanine aminotransferase, Four levels of blood lipids. Network pharmacology combined with molecular docking was used to screen the potential mechanism and target of Linggui Zhugan Decoction for the intervention of non-alcoholic fatty liver disease. Results: Linggui Zhugan Decoction significantly improved the levels of alanine aminotransferase and alanine aminotransferase in model rats (P<0.05). HE staining and oil red O staining showed that Linggui Zhugan Decoction significantly reduced liver lipid deposition in rats in the model group. Linggui Zhugan Decoction could significantly reduce the quadruplical levels of blood lipids in model rats (P<0.05). Network pharmacology screened out 10 key targets and 5 key signaling pathways;The molecular docking results showed that the first 20 active ingredients all had good binding ability to the top 10 targets. Conclusion: The results show that Linggui Zhugan Decoction has the effect of regulating blood lipids and improving liver tissue lesions in non-alcoholic fatty liver disease, and preliminarily verifies the regulatory effect of Linggui Zhugan Decoction on lipid metabolism-related genes.展开更多
