Aim Human umbilical vein endothelial cells(HUVEC) were incubated with high homocysteine(Hcy) in vitro,establishing inflammatory damage model of vascular endothelial cell,after intervening with Diplacone,to observe the effect of Diplacone on HUVEC,and to explore the possible protective effect of Diplacone on vascular endothelial cell. Methods HUVEC were pretreated with different concentrations of Hcy,choosing the optimal damage concentration and time of Hcy. HUVEC were treated with different concentration of...
