摘要: 为探讨有或无微量白蛋白尿的2型糖尿病患者血浆sICAM-1(可溶性细胞间黏附分子)、sVCAM-1(可溶性血管细胞黏附分子)水平的变化,并以血浆vWF水平作为内皮功能损伤的指标,观察血浆黏附分子水平与vWF水平之间的关系,应用ELISA法检测了82例2型糖尿病患者(其中57例尿白蛋白正常、25例伴微量白蛋白尿)的血浆sICAM-1、sVCAM-1、vWF水平,并与28例健康人作对照.再将结果与空腹血糖、糖化血红蛋白、尿微量白蛋白、三酰甘油、总胆固醇、高密度脂蛋白、低密度脂蛋白、空腹胰岛素水平进行相关分析.结果:在尿白蛋白正常且血浆vWF水平正常的2型糖尿病患者中,血浆sICAM-1水平已有显著升高(P<0.05),且与BMI、三酰甘油密切相关.提示:血浆sICAM-1可替代vWF作为2型糖尿病患者早期血管病变预测和监测的指标.

Abstract: The aim was to test the hypothesis that endothelial dysfunction is already evident in normoalbuminuric with type 2 diabetes.Previous studies have shown that the development of microalbuminuria is associated with the onset of endothelial dysfunction in individuals with type 2 diabetes.Plasma soluble intercellular adhesion molecule(sICAM-1), soluble vascular cell adhesion molecule(sVCAM-1), vWF were measured by ELISA in 28 healthy control subjects(groupⅠ), 57 normoalbuminuria individuals with type 2 diabetes(groupⅡ), and 25 microalbuminuria individuals with type 2 diabetes(groupⅢ).Plasma sICAM-1 levels were significantly higher in the groupⅡ and groupⅢ than that in the groupⅠ(P<0.05).In contrast plasma sVCAM-1 and vWF levels were elevated only in the groupⅢ compared with groupⅡ and groupⅠ(P<0.05).Correlated analysis showed a significant positive correlation between sICAM-1 and blood pressure,triglyceride, vWF, sVCAM-1.The results suggest that plasma sICAM-1 levels might be implicated in the development of diabetic vasculopathy, and could predict the onset of endothelial dysfunction instead of plasma vWF levels.The measurement of plasma sICAM-1 levels in type 2 diabetic patients may be clinically useful for early discovering of endothelial dysfunction.
