Objective: To investigate the impact and mechanism of the effective components recipe of Yangxintongmai Formula (YT-Ⅱ ) on angiogenesis of endothelium of rat with myocardial ischemia. Methods: The endothelial cell derived from the myocardial ischemic rat model was cultured and divided into YT-Ⅱ group and controlled groups including Yangxintongmai formula (YT Ⅰ) group, Shexiang-baoxin wan (SBW) group, b--FGF group, normal saline (NS) group and blank control group. Then the interference action on the "proliferation", "migration" ...
