摘要:

据统计,全球3.8亿人患有糖尿病,其患病率预计在不久将会大幅度增加。糖尿病的一个最严重的并发症是视网膜病变。目前对于糖尿病视网膜病变的治疗有激光光凝术、糖皮质激素或血管生成血管内皮生长因子等,只适用于早期的糖尿病性视网膜病变,而且副作用较大。因此,急需治疗糖尿病性视网膜病变的新手段。探讨了缺血性适应可能为寻找糖尿病性视网膜病变治疗新策略创造条件。缺血性是决定糖尿病性视网膜病变的病理生理学关键因素之一。缺血发生在视网膜血流量不足以满足视网膜的代谢需求时,不可逆转的形态和功能的变化可能会导致失明。暴露于无害的条件刺激能够短暂的引起抗缺血性损伤或缺血耐受。阿根廷布宜诺斯艾利斯大学Rosenstein医生表示,我们已经研制出一种“缺血疫苗”,可防止严重缺血。本文综述的新数据即显示缺血耐受作为治疗神经与血管改变引起的实验性糖尿病视网膜病变的有效性。

Abstract:

Diabetic retinopathy is a leading cause of acquired blindness, and it is the most common ischemic disorder of the retina. Available treatments are not very effective. Efforts to inhibit diabetic retinopathy have focused either on highly specific therapeutic approaches for pharmacologic targets or using genetic approaches to change expression of certain enzymes. However, it might be wise to choose innovative treatment modalities that act by multiple potential mechanisms. The resistance to ischemic injury, or ischemic tolerance, can be transiently induced by prior exposure to a non-injurious preconditioning stimulus. A complete functional and histologic protection against retinal ischemic damage can be achieved by previous preconditioning with non-damaging ischemia. In this review, we will discuss evidence that supports that ischemic conditioning could help avert the dreaded consequences that results from retinal diabetic damage.
