Effects of Shenqi Neijin powder on activation and apoptosis of hepatic stellate cells in rats with hepatic fibrosis.
Traditional herbal medicine is usually administrated according to experiences and practices. We aimed to investigate the anti-fibrotic effects of Shenqi Neijin powder (SQNJP) in hepatic fibrosis rats induced by carbon tetrachloride (CCl4). A total of 32 rats were divided into control group, model group, and SQNJP group. The hydroxyproline content was assayed. Histological features of liver tissues were determined with different staining methods. Western blotting analysis and immuno-fluorescence staining were performed to determine the expression of alpha-smooth muscle actin (α-SMA) and the activation of hepatic stellate cells (HSCs). Serial sections were stained with α-SMA immuno-fluorescence staining and the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling method (TUNEL) in turn to detect the apoptosis of HSCs. Fatty degeneration, deposition of collagen, and interval of fibers were noticed in rats induced by CCl4. After administration of SQNJP, remarkable decrease of fatty degeneration, deposition of collagen, and hydroxyproline content were noticed. Compared with the model group, significant decrease of α-SMA protein was noticed after administration of SQNJP, and remarkable apoptosis of HSCs was noticed after treating with SQNJP. SQNJP showed anti-fibrotic effects through inhibiting HSCs activation and inducing apoptosis of HSCs.
