目的 评估2型糖尿病患者(diabetes mellitus,DM)视网膜病变程度与颈总动脉内-中膜厚度(common carotid artery inti-ma-media thickness,CCA IMT)的相关性,以期早期发现糖尿病视网膜病变(diabetic retinopathy,DR)并评估其病变程度.方法 筛选2型糖尿病患者84例.根据眼底荧光造影的结果分为糖尿病无视网膜病变(non-diabetic retinopathy,NDR)组、非增殖期糖尿病视网膜病变(non-proliferative diabetic retinopathy,NPDR)组及增殖期糖尿病视网膜病变(proliferative di-abetic retinopathy,PDR)组三组.记录各组病例的性别、年龄、糖尿病病程,测量其CCA IMT、空腹血糖(fasting blood glu-cose,FBG)、糖化血红蛋白(glycosylated hemoglobin,HbA1c)、血清甘油三脂(serum triglycerides,TG)、总胆固醇(totalcholesterol,TC)、低密度脂蛋白胆固醇(low-density lipoprotein cholestero,LDL-C)及高密度脂蛋白胆固醇(high-density lipo-protein cholesterol,HDL-C).结果 CCA IMT、FBG、HbA1c及糖尿病病程均同DR的程度具有正相关性(P<0.05);且排除了FBG、HbA1c及糖尿病病程的影响后,CCA IMT仍与DR程度相关(P<0.01).结论 2型糖尿病患者DR的程度同CCA IMT具有正相关性.%Objective To estimate the correlation between the degree of the diabetic retinopathy(DR)and the common carotid artery intima-media thickness (CCA IMT)in type 2 diabetes mellitus(DM)for early detection of DR and the the extent of their lesions. Methods A total of 84 patients with type 2 diabetes mellitus,according to the result of fundus fluorescein angiography,were divided into three groups:non-diabetic retinopathy(NDR)group,non-proliferative diabetic retinopathy(NPDR)group and proliferative diabetic retinopathy(PDR)group. In each group, gender, age and duration of diabetes were recorded, and common carotid artery intima-media thickness(CCA IMT), fasting blood glucose (FBG) ,glycosylated hemoglobin( HbAlc), serum triglycerides(TG), total cholesterol(TC), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were measured. Results There was a positive correlation between the degree of DR and all of CCA IMT, FBG, HbAlc, and the course of diabetes(P＜0.05). And moreover,after ruling out the effect of FBG, HbAlc and the course of diabetes,there was still a positive correlation between CCA IMT and the degree of DR(P＜0. 01). Conclusions There is a positive correlation between the degree of DR with type 2 diabetes mellitus and the common carotid artery intima-media thickness.
