细胞因子与糖尿病视网膜病变的研究进展

糖尿病视网膜病变（DR）是一种发生进行性视力损害的糖尿病（DM）并发症,其特征是毛细血管闭锁、微循环障碍和局部缺血性视网膜新生血管形成,其确切的发病机制尚不清楚。最近有研究认为DR可能与视网膜毛细血管炎症反应有关。由于细胞因子能引起炎症反应和黏附分子表达,因此细胞因子增加单核细胞和内皮细胞黏附的过程被认为是DR发生发展过程中的关键事件。就血管内皮生长因子（VEGF）、转化生长因子-β（TGF-β）、碱性成纤维细胞生长因子（bFGF）等多种细胞因子在DR中的作用进行综述。

Recent progress in the investigation of cytokine and diabetes retinopathy

Diabetic retinopathy is a progressive vision-threatening complication of diabetes mellitus.The characters of diabetic retinopathy in clude capillary occlusion,microcirculation disturbance and retina neovascularization near ischemic areas of the retina.The exact pathogenic mechanism is still unclear.Recent studies showed that it may be related to vascular inflammation of the retina.Cytokines can cause induction of proinflammatory and adhesion molecules and thereby increase monocyte-endothelial cell adhesion,which is now accepted as the early key event in the development of diabetic retinopathy.The functions of many cytokines such as vascular endothelial growth factor,transforming growth factor-β,basic fibroblast growth factor and ideas for medicine therapeutic to diabetic retinopathy are summarized in this review.
