Abstract:
Objective:To explore the therapeutic effect of Fuzheng Huayu capsule on nonalcoholic fatty liver fibrosis induced by high trans fatty acid and high sugar diet in mice. Method:Forty SPF male C57/B6 mice were randomly divided into 4 groups （normal group， model group， Obelcholinic acid group， and Fuzheng Huayu capsule group）， with 10 mice in each group. Except 10 mice in the normal group， nonalcoholic fatty liver fibrosis was induced by high-fat and high-sugar diet for 24 weeks in the other 30 mice. From the 25th week of modeling， 4 groups received intragastric administration for 4 weeks， once a day： Fuzheng Huayu capsule group 4.8 g·kg-1. Oxycholic acid group 10 mg·kg-1. Model control group and normal group received the same volume of normal saline. Liver tissue and serum samples were collected at the end of the 28th week. The pathological changes of liver tissue of mice in each group were observed by hematoxylin-eosin （HE） staining， the degree of liver fibrosis was observed by Sirius red staining， the degree of lipid deposition was observed by oil red O staining， the content of hydroxypropylamine （Hyp） in liver tissue was determined by alkaline hydrolysis， and the change of triglyceride （TG） in liver tissue was detected by enzyme method. Serum alanine aminotransferase （ALT）， aspartate aminotransferase （AST） activities and fasting blood glucose （FBG） were detected by kit method， enzyme-linked immunosorbent assay （ELISA） was used to detect fasting Insulin （INS） level and calculate the changes of insulin resistance index （HOMA-IR）， liver fibrosis related mRNA and proteins of were detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）， Western blot and Immunohistochemistry. Result:Compared with the normal group， the liver tissue in the model group showed significant collagen fiber deposition， at mostly F2-F3 fibrosis stages， with increased number of inflammatory foci in liver tissue， obvious balloon degeneration and fatty degeneration of liver cells， significantly increased contents of Hyp and TG in liver tissue （P<0.01）， significantly increased activities of ALT and AST in serum and levels of FBG， INS and HOMA-IR （P<0.01）， and increased type I collagen （Col-Ⅰ）， Col-Ⅳ， α-smooth muscle agonist protein （α-SMA） and transforming growth factor-β （TGF-β） protein and mRNA in liver tissue. Compared with the model group， the collagen fiber deposition in liver tissue of mice in Fuzheng Huayu capsule group was significantly reduced， at mostly F0-F1 fibrosis stages， with significantly improved balloon-like change of hepatocytes， and significantly reduced number of inflammatory foci in lobules （P<0.05，P<0.01）. Compared with the model group， Fuzheng Huayu capsule can significantly reduce the content of Hyp in liver tissue， the levels of serum ALT and AST， and the expression of Col-Ⅰ， Col-Ⅳ， α-SMA and TGF-β genes and proteins in mice （P<0.05，P<0.01）. Conclusion:Fuzheng Huayu capsule has a good therapeutic effect on nonalcoholic fatty liver fibrosis induced by high trans fatty acid and high sugar diet in mice.
