Aim To study the protective effect of the naringin on chemotactic factor CX3CL1 of humanumbilical vein endothelial cells( HUVEC) induced by high glucose. Methods The effect of different concentrations of naringin on HUVEC cell viability was determined by MTS. HUVECs were divided into 4 groups:(1) control group,(2) high glucose group,(3) naringin group and(4) high glucose treated with naringin group.After treatment for 5 days,the concentration of nitric oxide( NO) in the culture medium was measured by nitrat...
