探讨2型糖尿病患者血浆纤溶活性因子组织型纤溶酶原激活物(t-PA)、纤溶酶原激活物抑制物-1(PAI-1)水平与颈动脉粥样硬化(carotid atherosclerosis,CAS)的关系.将91例2型糖尿病患者根据颈动脉超声内膜中层厚度分为4组并设健康对照组,分析CAS程度与血浆t-PA、PAI-1水平的关系.结果显示CAS程度与t-PA水平呈明显负相关(r=-0.723,P＜0.01),与PAI-1水平均呈明显正相关(r=0.851,P＜0.01).提示2型糖尿病患者纤溶功能异常可能参与了大血管粥样硬化的发生、发展过程.

The association of plasma tissue type plasmingogen activator (t-PA) and plasminogen activator inhibitor (PAI-1) with carotid atherosclerosis in patients with type 2 diabetes was explored.The subjects with type 2 diabetes (n =91) and control subjects (n =30) were enrolled for this study.According to carotid artery intima media thickness in Color Doppler Ultrasonography,the subjects with type 2 diabetes were divided into four groups:normal carotid group(group 1,n =25),lining thickening group (group 2,n =30),stable plaques group (group 3,n =23),carotid stenosis group(group 4,n =13).Plasma t-PA and PAI-1 levels were measured by ELISA.Compared with the control group,there was no significant change in the levels of plasma t-PA and PAI-1 in group 1 (P＞0.05),plasma t-PA activity was decreased significantly(P＜0.05) and PAI-1 activity increased obviously (P＜0.05) in group 2,group 3,and group 4.Carotid atherosclerosis degree was negatively correlated with t-PA(r=-0.723,P＜0.01) and positively correlated with PAI-1 (r=0.851,P＜0.01).The results suggested that the abnormal fibrinolysis function may take part in the development of atherosclerosis of carotid arteries in patients with type 2 diabetes.
