2型糖尿病是世界范围内的一个主要健康问题,发病率较高[1]。糖尿病对人体的损害主要是其引发的各种慢性并发症。动脉粥样硬化是糖尿病大血管病变的病理过程。在临床上,动脉硬化最直接、最方便的诊断方法是B超下可见斑块形成或内膜的增厚。颈动脉内膜-中膜厚度(CIMT)、斑块用作亚临床动脉粥样硬化的早期指标,是未来死亡和心血管事件的强预测因子[2]。有研究[3-4]发现胱抑素C与心血管疾病有关,内脏型肥胖者容易发生心血管疾病。本文通过探讨内脏脂肪面积、血清胱抑素C与2型糖尿病颈动脉硬化的关系,定期监测胱抑素C和内脏脂肪面积有助于为颈动脉硬化的预防和早期诊断提供参考。

摘要:
目的探讨内脏脂肪面积、血清胱抑素C与2型糖尿病颈动脉硬化的相关性。 方法选择2型糖尿病病人127例,根据是否发生颈动脉粥样硬化分为单纯2型糖尿病组(对照组)40例和2型糖尿病合并颈动脉硬化组(硬化组)87例,检测内脏脂肪面积、血清胱抑素C及其他指标,分析内脏脂肪面积、血清胱抑素C与2型糖尿病颈动脉硬化的相关性。 结果单因素分析显示,硬化组年龄、体质量指数、收缩压、病程、胱抑素C、内脂肪面积均大于对照组(P < 0.05~P < 0.01);logistic回归分析显示,胱抑素C、内脏脂肪面积、年龄是2型糖尿病病人发生颈动脉硬化的危险因素。 结论胱抑素C和内脏脂肪面积与2型糖尿病颈动脉硬化有关,可为2型糖尿病颈动脉硬化的早期诊断提供参考。 Abstract:ObjectiveTo explore the correlation of visceral fat area and serum cystatin C with carotid atherosclerosis in type 2 diabetes mellitus. MethodsAccording to whether having carotid artery aterosclerosis, 127 patients with type 2 diabetes mellitus were divided into the simple diabetes mellitus group(control group, 40 cases) and type 2 diabetes mellitus complicated with carotid atherosclerosis(sclerosis group, 87 cases).The visceral fat area, serum cystatin C and other indexes were detected, and the correlation of visceral fat area and serum cystatin C with carotid atherosclerosisin type 2 diabetes mellitus were analyzed. ResultsThe age, body mass index, systolic blood pressure, course of disease, cystatin C and visceral fat area in sclerosis group were greater than those in control group(P < 0.05 to P < 0.01).The results of logistic regression analysis showed that the cystatin C, visceral fat area and age were the risk factors of carotid atherosclerosis in patients with type 2 diabetes mellitus. ConclusionsThe cystatin C and visceral fat area are related to the carotid atherosclerosis in type 2 diabetes mellitus, which may provide a reference for early diagnosis of carotid atherosclerosis in type 2 diabetes mellitus. -
