糖尿病视网膜病变(DR)是2型糖尿病(T2DM)最常见的微血管并发症之一,具有高发病率、高致盲率和高复发率的特点[1]。其发病原因尚未完全阐明,推测微血管扩张,基底膜增厚,动静脉短路导致微血管缺血是视网膜病变的触发步骤[2-4]。目前1/2以上的世界人口感染幽门螺杆菌(Hp),但Hp感染与糖尿病的关系认识不一。部 Diabetic retinopathy (DR) is one of the most common microvascular complications of type 2 diabetes mellitus (T2DM), with high morbidity, high blinding rates and high recurrence rates [1]. The etiology has not been fully elucidated, speculated that microvascular dilatation, thickening of the basement membrane, arteriovenous ischemia leading to retinal ischemia trigger step [2-4]. At present, more than one-half of the world’s population is infected with Helicobacter pylori (Hp), but the relationship between Hp infection and diabetes is not well understood. unit
