Objective To observe the changes of angiopoietin 2(Ang-2)and vascular endothelial cadherin(VEcadherin)in vascular endothelial cells injured by analogue trauma stress induced by intracellular heat shock protein 70(e HSP70),and to explore the protective effect of Xuebijing Injection(XI)on the endothelial cells. Methods The expression levels of Ang-2 and VE-cadherin m RNA and protein in the cultured human umbilical vein endothelial cells(HUVEC)were monitored at hour 0, 2, 4, 8, 16, 32 after e HSP70 stimulation...
