Abstract:
Objective To investigate the effect of Huatan Qushi Huoxue prescription on the ultrastructure of hepatocyte mitochondria in a rat model of nonalcoholic steatohepatitis (NASH). Methods A total of 48 male Sprague-Dawley rats were randomly divided into blank group, model group, Yishanfu group, and Huatan Qushi Huoxue prescription group, with 12 rats in each group. The rats in the model group and the drug groups were administered and modeled since week 2; the rats in the blank group were given normal diet, and those in the other three groups were given high-fat diet. Based on dose conversion between human and animal, the equivalent dose of Huatan Qushi Huoxue prescription was 1.26 g/100 g body weight, and the equivalent dose of polyene phosphatidylcholine capsules (Yishanfu) was 0.014 18 g/100 g body weight. The rats in the model group were given 0.9% sodium chloride by gavage, those in the Yishanfu group were given polyene phosphatidylcholine suspension by gavage, and those in the traditional Chinese medicine group were given the granules of Huatan Qushi Huoxue prescription by gavage, once a day for 10 consecutive weeks. A transmission electron microscope was used to observe liver ultrastructure and perform a quantitative analysis. A one-way analysis of variance was used for comparison of continuous data between multiple groups; for further pairwise comparison, the least significant difference t -test was used for data with homogeneity of variance, and the Dunnett's T3 was used for data with heterogeneity of variance. Results The model group had a large number of lipid droplets accumulated in hepatocytes, changes in mitochondrial morphology and structure, and reductions in the number of mitochondria and endoplasmic reticulum. The Huatan Qushi Huoxue prescription group had a significant reduction in lipid droplets in hepatocytes and significant increases in the number of mitochondria and endoplasmic reticulum compared with the model group, with intact mitochondrial membrane and structure. The Yishanfu group had a reduction in lipid droplets in hepatocytes, an increase in the number of mitochondria, and a reduction in the number of endoplasmic reticulum, with relatively intact mitochondrial membrane and structure. The quantitative analysis showed that compared with the blank group, the model group had a significant increase in the area of lipid droplets and a significant reduction in mitochondria, with a significant difference in mitochondrial density between the two groups (all P < 0.01); after drug intervention, the Yishanfu group had a significant reduction in the area of lipid droplets and a significant increase in the number of mitochondria, with a significant difference in mitochondrial density between the Yishanfu group and the model group (all P < 0.01); compared with the Yishanfu group, the traditional Chinese medicine group had a significantly greater reduction in the area of lipid droplets and a significant increase in the number of mitochondria, with a significant difference in mitochondrial density between the two groups (all P < 0.05). Conclusion Huatan Qushi Huoxue prescription can improve lipid accumulation, increase mitochondrial density, and protect mitochondrial structure and function, with a better clinical effect than Yishanfu.
