Objective: To evaluate the effects of Xiayuxue Decoction, a compound traditional Chinese medicine, on liver angiogenesis in rats with carbon tetrachloride (CCl4)-induced liver fibrosis. Methods: Liver cirrhosis was induced by intraperitoneal injection of 50% CCl4-olive oil solution at the dose of 1 mL/kg body weight, twice per week for 9 consecutive weeks. After 3- and 6-week injection, 6 rats in the normal group and 6 rats in the model group were randomly sacrificed for dynamic observation. The survival rats of model group were randomly divided into model group (n=15) and Xiayuxue Decoction group (n=11). Six normal rats were used as a normal control. Xiayuxue Decoction was administered orally starting from the 7th week for 3 weeks. At the end of the ninth week, animals were sacrificed and liver tissues were harvested to measure histological changes, activities of matrix metalloproteinase-2 (MMP-2) and MMP-9 and protein expressions of platelet endothelial cell adhesion molecule-1 (CD31), von Willebrand factor (vWF), vascular endothelial growth factor (VEGF), vascular endothelial growth factor receptor-2 (VEGFR2), complement decay-accelerating factor (DAF) and α-smooth muscle actin (α-SMA) in the liver tissues. Results: Compared with the normal group, liver injury, fatty degeneration and collagen deposition were evidently observed in the model group and protein expressions of CD31, vWF, VEGF, VEGFR2, DAF and α-SMA were gradually increased. In addition, the activities of MMP-2 and MMP-9 in liver tissues were enhanced in the model group (P
