2型糖尿病患者尿白蛋白排泄率与血浆纤溶活性的相关性分析

目的 探讨2型糖尿病患者24 h尿微量白蛋白排泄率(UAE)与血浆纤溶活性改变的关系.方法 129例2型糖尿病患者根据UAE分为尿白蛋白正常组、微量白蛋白尿组和大量白蛋白尿组,并以40例健康人为对照组,采用发光底物法测定血浆组织型纤溶酶原激活物(t-PA)和纤溶酶原激活抑制物-1(PAI-1)活性,计算PAI-1/t-PA,并进行UAE、血糖、血脂、血尿素氮、肌酐测定.结果 与健康对照组比较,2型糖尿病患者血浆PAI-1活性显著增高,t-PA活性显著降低(P＜0.01);三组2型糖尿病患者PAI-1/t-PA比值差异有统计学意义(P＜0.05),以大量蛋白尿组患者PAI-1/t-PA比值最高;单因素相关分析发现,AER与PAI-1/t-PA比值呈正相关,其中以微量白蛋白尿组最为明显(r=0.5422,P＜0.001).结论 2型糖尿病患者尿白蛋白排泄率与血浆纤溶活性密切相关.

The association of urinary albumin excretion with fibrinolytic activity in patients with type 2 diabetes

Objective To examine the relationship between UAE and fibrinolytic activity in patients with type 2 diabetes.Methods 129 type 2 diabetic patients recruited and subgrouped by UAE,and the UAE,FBS,lipids,renal function and the activity of t-PA and PAI-1 were conducted in these patients and 40 health people.Results Compared to control group,the activity of PAI-1 was increased and the activity of t-PA decreased dramaticlly in type 2 diabetic group(P＜0.05);there was significant difference in the ratio of PAI-1 and t-PA between three diabetic groups(P＜0.05),of three group the ratio of PAI-1 and t-PA was most highest in the patients with macroal buminuria,and simple correlation analysis showed positive correlation between UAE and the ratio of PAI-1 and t-PA,especially in the patients with microalbuminuria(r=0.321,P＜0.05).Conclusion The UAE is closely relatedto fibrinolytic activity in patients type 2 diabetes.
