【摘要】 目的:探讨2型糖尿病患者血浆致动脉粥样硬化指数(AIP)与其他致动脉粥样硬化(AS)危险因素的相关性。方法:152例2型糖尿病患者以AIP值0.06为切点,分为非致动脉硬化表型组(N组65例:AIP<0.06)和致动脉硬化表型组(A组87例:AIP≥0.06),比较两组间的临床生化指标。结果:A组体重指数(BMI)、腰臀比、胰岛素抵抗指数(HOMA-IR)、胰岛素分泌指数(HOMA-β)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、极低密度脂蛋白胆固醇(VLDL-C)、血尿酸均高于N组(P<0.05或P<0.01),高密度脂蛋白胆固醇(HDL-C)低于N组(P<0.01),且冠心病发病率较高(P<0.05)。相关分析表明,AIP与BMI、腰臀比、收缩压、舒张压、HOMA-IR、HOMA-β、TC、TG、LDL-C、VLDL-C、血尿酸呈正相关(P<0.05),与HDL-C负相关(P<0.01)。Logistic Regression分析结果显示,HDL-C、LDL-C、VLDL-C、TG是AIP的独立影响因素(P<0.01)。结论:2型糖尿病患者中,能间接反应LDL-C颗粒大小的指标AIP与肥胖和胰岛素抵抗、高胰岛素血症、HDL-C、VLDL-C、TG、血尿酸等其他致AS危险因素密切相关,控制这些危险因素有利于降低AIP,从而减缓AS的发生和发展。

【Abstract】 Objective:To study the patients with type 2 diabetes mellitus (T2DM) plasma atherosclerosis index (AIP) and for other risk factors for atherosclerosis (AS).Method:152 patients with T2DM with AIP value of 0.06 as the point of tangency were selected, and they were divided into send arteriosclerosis of the phenotypic group (the group N 65 cases: AIP < 0.06) and the atherosclerosis phenotypic group (the group A 87 cases: AIP 0.06 or higher), the clinical and biochemical indexes between two groups were compared.Result:The body mass index (BMI), waist hip ratio, and insulin resistance (HOMA IR) and insulin secretion index (HOMA-β), triglycerides (TG), low-density lipoprotein cholesterol (LDL - C), low density lipoprotein cholesterol (VLDL -C), blood uric acid in the group A were higher than those of the group N (P<0.05 or P<0.01), high density lipoprotein cholesterol (HDL - C) less than the group N (P<0.01), the higher incidence of coronary heart disease (P<0.05). Correlation analysis showed that AIP and BMI, waist hip ratio, systolic pressure, diastolic pressure, HOMA IR, HOMA -β, TC, TG, LDL and VLDL -C, blood uric acid positive correlation (P<0.05), and negatively correlated to HDL - C (P<0.001). Logistic Regression analysis showed, HDL - C, LDL -C, VLDL -C, TG were the independent factors affected the AIP (P<0.01).Conclusion:In patients with type 2 diabetes, can indirect reactions of LDL - C particle size index AIP, with obesity and insulin resistance, hyperinsulinemia is HDL - C, VLDL -C, TG and blood uric acid and other closely related to AS risk factors, control these risk factors is beneficial to reduce the AIP, slowing the occurrence and development of AS.

大血管并发症是2型糖尿病患者致死致残的主要原因,动脉粥样硬化(AS)是导致大血管并发症的主要因素,目前糖尿病患者发生动脉硬化的机制尚未完全阐明。研究表明低密度脂蛋白胆固醇(LDL-C)颗粒直径大小与动脉粥样硬化(AS)具有密切的关系[1]。血浆致动脉粥样硬化指数(atherogenic index of plasma,AIP)是指甘油三酯(TG)与高密度脂蛋白胆固醇(HDL-C)比值的对数[2]。AIP作为一项新的血脂指标,与LDL-C颗粒直径大小呈负相关,可作为间接反应LDL-C颗粒大小的指标,可作为2型糖尿病患者发生大血管并发症危险性的一个指标[3-4]。最近研究发现,2型糖尿病患是冠心病的重要危险因素,且合并高AIP[5]。本文对2型糖尿病患者的AIP的相关危险因素进行了分析,探讨导致2型糖尿病患者AS的危险因素,以期更好地控制糖尿病大血管并发症。
1 资料与方法
1.1 一般资料 选取2011年1月-2013年6月于本院内分泌专科初诊住院的2型糖尿病患者152例进行横断面调查研究。患者均签署知情同意书,均符合1999年WHO糖尿病诊断标准,年龄20~70岁,平均(48.27±10.01)岁,糖尿病病程0~10年。因习惯上以LDL-C颗粒直径小于25.5 nm为致动脉硬化表型,而25.5 nm对应的AIP为0.06[2]。因此以AIP值0.06为切点,将研究对象分为非致动脉硬化表型组(N组):AIP<0.06,65例;致动脉硬化表型组(A组):AIP≥0.06,87例。冠心病的诊断标准(满足下列一项即可):(1)既往陈旧心肌梗死病或急性心肌梗死。(2)冠状动脉造影证实有冠状动脉≥70%的狭窄。(3)典型心绞痛病史以及典型的ST-T改变。排除标准包括:入院前1周内应用口服降糖药、胰岛素、降压药、降脂药、降尿酸等,入院时有应激、感染及酮症并发症。
1.2 研究方法 (1)体格检查:在髂嵴和第12肋下缘连线的中点水平测量腰围,在大转子水平测量臀围,测量身高、体重,腰臀比的计算为腰围/臀围,体重指数(BMI)的计算为体重(kg)/身高2(m2),测量右上臂血压,测量3次取平均值。……
