摘要
With the high incidence of diabetes around the world,ischemic complications cause a serious influence on people’s production and living.Neovascularization plays a significant role in its development.Therefore,neovascularization after diabetic ischemia has aroused attention and has become a hot spot in recent years.Neovascularization is divided into angiogenesis represented by atherosclerosis and arteriogenesis characterized by coronary collateral circulation.When mononuclear macrophages successively migrate to the ischemia anoxic zone after ischemia or hypoxia,they induce the secretion of cytokines,such as vascular endothelial growth factor and hypoxia-inducible factor,activate signaling pathways such as classic Wnt and phosphatidylinositol 3 kinase(PI3K)/protein kinase B(Akt)pathways,trigger oxidative stress response,activate endothelial progenitor cells or enter the glycolysis or lactic acid process and promote the formation of new blood vessels,remodeling them into mature blood vessels and restoring blood supply.However,the hypoglycemic condition has different impacts on neovascularization.Consequently,this review aimed to introduce the mechanisms of neovascularization after diabetic ischemia,increase our understanding of diabetic ischemic complications and their therapies and provide more treatment options for clinical practice and effectively relieve patients’pain.It is believed that in the near future,neovascularization will bring more benefits and hope to patients with diabetes.
