摘要

To investigate the effects of ancient Chinese medical formula Xiayuxue Decoction (下瘀血汤

XYXD) on activation of hepatic stellate cells (HSCs) and defenestration of sinusoidal endothelial cells (SECs) in CCl4-induced fibrotic liver of mice. High performance liquid chromatography was used to identify the main components of XYXD and control the quality of extraction. C57BL/6 mice were induced liver fibrosis by CCl4 exposure and administered with XYXD for 6 weeks simultaneously. Liver tissue was investigated by hematoxylin-eosin and Sirius-red staining. Sinusoidal fenestrations were observed by scanning electronic microscopy and fluorescent immunohistochemistry of PECAM-1 (CD31). Whole liver lysates were detected of α-smooth muscle actin (α-SMA) and type-I collagen by Western blot. Primary rat HSCs-T6 cells were analyzed by detecting α-SMA

respectively. Amygdalin and emodin in XYXD were identified. XYXD (993 mg/kg) inhibited Sirius red positive area up to 70.1% (P<0.01)

as well as protein levels of α-SMA and type-I collagen by 42.0% and 18.5% (P<0.05) respectively. In vitro

XYXD (12.5 μg/mL

50 μg/mL) suppressed the activation of HSCs and reversed the myofibroblastic HSCs into quiescent

demonstrated as inhibition of fluorescent F-actin by 32.3% and 46.6% (P<0.05). Besides

XYXD induced the apoptosis of HSC-T6 cells by 20.0% (P<0.05) and 49.5% (P<0.01)

evidenced by enhanced TUNEL positivity. Moreover

ultrastructural observation suggested XYXD inhibited defenestration of SECs

which was confirmed by 31.1% reduction of protein level of CD31 (P<0.05). XYXD inhibited both HSCs activation and SECs defenestration which accompany chronic liver injuries. These data may help to understand the underlying mechanisms of XYXD for prevetion of chronic liver diseases.
