目的分析糖尿病患者颈动脉彩超的临床意义及其与代谢相关因素的相关性，以寻找在基层医院进行预筛时的替代指标。方法418例患者按照颈动脉彩超检查结果分为正常组(内中膜度厚度<0.9 mm、无斑块及狭窄)和异常组(内中膜度厚度≥0.9 mm有斑块或狭窄者)；选取与代谢相关的因素(如血压、腰围、颈围、BMI、血糖、血脂)等数据，进行数据分析；比较两组患者各相关指标之间的差异。结果颈动脉检查正常组中颈围、腰围、收缩压，明显低于异常组，两组差异有统计学意义(<0.01)；空腹血糖正常组低于异常组，两组差异有统计学意义(<0.05)；高密度脂蛋白胆固醇正常组高于异常组，两组差异有统计学意义(<0.01)。结论颈围、腰围、收缩压、空腹血糖、HDL均与大血管病变存在关联性，其中颈围可推荐作为基层医院筛查颈动脉异常的预筛指标进行推荐。“,”Objective Analysis the carotid artery color Doppler of diabetic patients and its relationship with metabolic factors, to find alternative indicators for pre-screen in the primary hospital. Methods According to the results of carotid artery ultrasonography, 418 patients were divided into normal group (intima-media of thickness<0.9mm, no plaque and stenosis) and abnormal (intima-media thickness ≥ 0.9mm of plaque or stenosis); select the factors related to metabolism (such as blood pressure, waist, neck circumference, BMI and blood glucose, blood lipid), compare the dif erences between the two groups of patients al relevant indexes. Results Carotid ultrasound in normal group, neck circumference, waist circumference, systolic blood pressure, which is significantly lower than that in abnormal group, there are significant dif erence between two groups ( <0.01);fasting blood glucose in normal group is lower than the abnormal group, there was significant dif erence between two groups ( <0.05);high density lipoprotein cholesterol in normal group is higher than the abnormal group, there was significant dif erence between two groups ( <0.01). Conclusion Neck circumference, waist circumference, systolic blood pressure, fasting blood glucose, HDL are associated with vascular disease, the neck circumference can be recommended as the pre screening index for carotid artery abnormal at primary hospital.
