Abstract:
Objective To investigate the effect of Xuefu Zhuyu decoction on nonalcoholic fatty liver disease (NAFLD) and its material basis. Methods In experiment 1 for exploring the effect of Xuefu Zhuyu decoction on mice with NAFLD induced by high-fat diet, 50 healthy male C57BL/6J mice were randomly divided into normal group, model group, high- and low-dose Xuefu Zhuyu decoction groups, and obeticholic acid control group, with 10 mice in each group. The mice in the normal group were given control diet, and those in the other groups were given high-fat diet. Gastric administration was started at week 13, and related samples were collected at the end of week 16. Food intake and body weight were recorded, enzyme-linked immunosorbent assay was used to measure the serum level of fasting insulin, fasting blood glucose was measured, and insulin resistance index was calculated. HE staining and NAFLD activity score (NAS) were used to observe liver histopathology in mice, oil red O staining was used to observe lipid deposition, and triglyceride (TG) level in liver tissue and serum alanine aminotransferase (ALT) level were measured. In experiment 2 for exploring the effect of different extracts of Xuefu Zhuyu decoction on mice with NAFLD induced by high-fat diet, the methods of water decocting, water extraction and alcohol precipitation, and petroleum ether extraction were used to obtain the extracts 1, 2, and 3 of Xuefu Zhuyu decoction, and 54 healthy male C57BL/6J mice were randomly divided into normal group, model group, Xuefu Zhuyu decoction extract 1, 2, and 3 groups, and Xuefu Zhuyu decoction control group, with 9 mice in each group. The mice in the normal group were given control diet, and those in the other groups were given high-fat diet. Gastric administration was started at week 13, and related samples were collected at the end of week 16. Food intake and body weight were recorded, and enzyme-linked immunosorbent assay was used to measure the serum level of fasting insulin, fasting blood glucose was measured, and insulin resistance index was calculated. HE and NAS were used to observe liver histopathology in mice, oil red O staining was used to observe lipid deposition, and the levels of TG and gamma-glutamyl transpeptidase (GGT) in liver tissue and the serum level of ALT were measured. The t -test was used for comparison of normally distributed continuous data between two groups; a one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t -test was used for further comparison between two groups. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups and further comparison between two groups. Results In experiment 1, compared with the model group, the high- and low-dose Xuefu Zhuyu decoction groups and the obeticholic acid control group had significant reductions in body weight, insulin resistance index, the distribution of vacuolar lipid droplets in liver tissue, intralobular inflammation, the ballooning degeneration of hepatocytes, NAS score, the level of TG in liver tissue, and the serum level of ALT (all P < 0.05). Compared with obeticholic acid, high- and low-dose Xuefu Zhuyu decoction had a significantly better effect in reducing body weight, insulin resistance index, and total NAS score (all P < 0.05), and low-dose Xuefu Zhuyu decoction had a significantly better effect in improving serum ALT ( P < 0.05). In experiment 2, compared with the model group, the Xuefu Zhuyu decoction extract 1, 2, and 3 groups had significant reductions in fasting blood glucose, insulin resistance index, the distribution of lipid droplets in liver tissue, intralobular inflammation lesions, the ballooning degeneration of hepatocytes, total NAS score, and the level of TG in the liver (all P < 0.05). Compared with the model group, the extract 1 group had a significant reduction in body weight ( P < 0.05); the extract 2 and 3 groups had a significant reduction in the serum level of ALT ( P < 0.05); the extract 2 group had a significant reduction in the level of GGT in liver tissue ( P < 0.05). The extract 2 of Xuefu Zhuyu decoction had the closest effect to compound Xuefu Zhuyu decoction. Conclusion Xuefu Zhuyu decoction and its extracts can help to achieve varying degrees of improvement in NAFLD induced by high-fat diet in mice, and the extract 2 of Xuefu Zhuyu decoction might be the main material basis for Xuefu Zhuyu decoction.
