摘要: 目的 探讨血浆同型半胱氨酸(Hcy)、血清25-羟维生素D3[25-(OH)D3]水平与青年糖尿病患者颈动脉内膜中层厚度(CIMT)的关系。 方法 选取107例青年糖尿病患者作为研究对象,采用颈部血管超声测量CIMT,并依据CIMT值将患者分成3组,分别为重度增厚组(n=29)、轻度增厚组(n=33)以及未增厚组(n=45), 并选取107例同期体检的健康青年志愿者为对照组。检测所选受试者血浆Hcy和血清25-(OH)D3水平,观察各组患者Hcy和25-(OH)D3指标水平差异及其与CIMT的关系。 结果 重度增厚组、轻度增厚组和未增厚组患者血浆Hcy水平均显著高于对照组(P<0.05), 血清25-(OH)D3水平均显著低于对照组(P<0.05)。受试者CIMT与血浆Hcy水平呈正相关(r=0.463, P<0.001), 而与血清25-(OH)D3水平呈负相关(r=-0.339, P<0.001)。经Logistic回归分析,高水平血浆Hcy与低水平血清25-(OH)D3均是青年糖尿病患者CIMT增厚的独立危险因素(P<0.001)。 结论 青年糖尿病患者血浆Hcy与血清25-(OH)D3水平可在一定程度上反映CIMT状况,均可作为评价患者大血管病变发生风险的重要指标,为青年糖尿病患者的临床诊治提供指导。Abstract: Objective To study the relationship between plasma homocysteine(Hcy), serum 25-hydroxyvitamin D3(25-(OH)D3)levels and carotid intima-media thickness(CIMT)in young diabetic patients. Methods A total of 107 young diabetic patients were selected as research objects. CIMT was measured by neck vessels ultrasound, and these patients were divided into severe thickening group(n=29), mild thickening group(n=33)and thickening-free group(n=45)according to the values of CIMT, and 107 healthy volunteers in the same period with physical examinations were selected as control group. The plasma Hcy and serum 25-(OH)D3 levels were detected, and their differences in differed groups and their relationship with CIMT were observed. Results Severe thickening group, mild thickening group and thickening-free group had significantly higher plasma Hcy levels that the control group(P<0.05), and significantly lower serum 25-(OH)D3 levels than the control group(P<0.05). The subjects' CIMT had a positive correlation with plasma Hcy level(r=0.463, P<0.001), and a negative correlation with serum 25-(OH)D3 level(r=-0.339, P<0.001). Logistic regression analysis showed that high level of plasma Hcy and lower level of serum 25-(OH)D3 were both independent risk factors of CIMT thickening for young patients with diabetes(P<0.001). Conclusion The levels of plasma Hcy and serum 25-(OH)D3 in young diabetic patients can reflect the condition of CIMT to a certain extent, and can be used as important indicators to evaluate the risk of macro-vascular disease in young diabetic patients. Meanwhile, they provide guidance - for the diagnosis and treatment of these patients.
