The changes of ICAM-1, VEGF and nitric oxide (NO), von Willebrand factor (vWF), endothelin-1 (ET-1) and thrombomodulin (TM) and other vascular endothelial function indexes in four groups were compared.Results:NDR group, BDR group, PDR group, ICAM-1, VEGF, NO and vWF (except NDR group), four ET-1 TM and vascular endothelial function indexes were significantly higher than the control group, while the difference between NDR vWF group was not statistical significant;differences in ICAM-1, VEGF and NO, vWF, ET-1 and TM four vascular endothelial function index among NDR group, BDR group and PDR group were statistically significant. Compared with the two groups, four vascular endothelial function indexes of ICAM-1, VEGF and NO, vWF, ET-1 and TM in retinopathy group were significantly higher than those in control group. Conclusions:There is correlation between VEGF, ICAM-1 level and microvascular injury in senile diabetic retinopathy patients. The late progression of the disease is, the higher VEGF, ICAM-1, NO, vWF, ET-1 and TM of vascular endothelial damage indexes are.It can reflect the microcirculation the extent of injury and blood rheology, and change of coagulation mechanism. It is worthy for clinical reference.展开更多
