糖尿病视网膜病变(DR)是眼科常见病,常导致患者视力不可逆性下降,其2大特征包括黄斑水肿,视网膜新生血管生成;而视网膜新生血管生成是导致患者视力丧失最重要的原因之一.内皮抑素(ES)各种作用的发挥与其特有的结构特点密不可分,是目前公认的最强的抑制血管生长的因子之一,ES抑制视网膜新生血管的作用机制复杂,且尚未完全明确.因此,本文拟从ES调控细胞外基质的表达、抑制促血管生成蛋白的表达、调控关键信号通路的表达3个方面阐述ES抑制糖尿病视网膜新生血管病变的可能机制,并作一综述.%Diabetic retinopathy (DR) is a common disease of ophthalmology,often causes irreversible decline of patients' vision,which has two features including macular oedema,diabetic retinal neovascularization.Diabetic retinal neovascularization is one of the most important reasons leading to blindness.Endostatin (ES) is one of the most effective agents inhibiting angiogenesis,whose biological function has a close relationship with its chemical construction.However,its mechanisms of treating diabetic retinal neovascularization are very complicated and remain unclear.Therefore,in this review we summarized several possible mechanisms,including regulating the expression of extracellular matrix,inhibiting the expression of pro-angiogenic factors,and regulating the signaling pathways,by which ES may inhibiting diabetic retinal neovascularization.
