测定 1 0 0例Ⅱ型糖尿病患者平均血小板体积 (MPV) ,血小板压积 (PGT) ,血小板分布宽度 (PDW ) ,血小板计数 (PLT) ,并与 50例健康人比较 ,发现Ⅱ型糖尿病平均MPL、PLT、PDW高于对照组 (P <0 0 5) ,说明Ⅱ型糖尿病存在血小板功能异常。比较有视网膜病变与无视网膜病变且与对照组之间关系 ,示均有显著性差异 (P <0 0 5) ,而以有视网膜病变组差异更为显著 (P <0 0 1 ) ,说明血小板功能异常在视网膜病变的发生发展中起重要作用 The average platelet volume (MPV), platelet pressure (PGT), platelet distribution width (PDW) and platelet count (PLT) were measured in 100 patients with type 2 diabetes mellitus, and compared with 50 healthy subjects, , PLT, PDW higher than the control group (P <0 05), indicating that type 2 diabetes platelet dysfunction. There was a significant difference between retinopathy and non-retinopathy (P <0.05), but there was more significant difference between the two groups (P <0.01), indicating that platelet Abnormal function plays an important role in the occurrence and development of retinopathy
