糖尿病视网膜病变血栓前状态分子标志物的研究

目的:观察糖尿病视网膜病变患者血浆中血栓调节蛋白、血管性血友病因子、纤溶酶原激活剂抑制物-1水平的变化,探讨血栓前状态分子标志物与糖尿病视网膜病变的关系。方法:将63例2型糖尿病患者分为:无糖尿病视网膜病变组35例,糖尿病视网膜病变组28例,同期健康体检者30例为对照组。测定各组血浆血栓调节蛋白、血管性血友病因子、纤溶酶原激活剂抑制物-1的水平,并对上述指标进行比较。结果:2型糖尿病患者血浆血栓调节蛋白、血管性血友病因子、纤溶酶原激活剂抑制物-1水平均明显高于对照组(P<0.01);糖尿病视网膜病变组也明显高于无糖尿病视网膜病变组(P<0.01)。结论:糖尿病患者存在血管内皮损伤,抗凝作用减弱,血小板黏附与聚集,纤溶活性下降,可能是糖尿病视网膜病变的发病机制之一。

Study on molecule marker of pro-thromb state with diabetic retinopathy

Objective To study the relationship between molecule marker of pro-thromb state and diabetic retinopathy by detecting the levels of thrombomodulin,von Willebrand disease factor,plasminogen activator inhibitor-1 in blood plasma.Methods Sixty-three patients with type 2 diabetic mellitus were divided into two groups,35 patients not complicated with diabetic retinopathy group and 28 patients with diabetic retinopathy.And the other 30 health people were as normal controls.The levels of thrombomodulin,von Willebr...
