【摘要】 目的探讨多因素干预条件下新诊2型糖尿病患者亚临床动脉粥样硬化(AS)进展的危险因素。方法前瞻性观察156例年龄35～70岁、病程在1年以内、无亚临床动脉粥样硬化的2型糖尿病患者在采取以抗血小板为基础的强化血糖、血脂、血压、体重等综合达标干预措施的2年中各代谢指标和亚临床动脉粥样硬化的动态变化,比较强化干预2年后发生与未发生亚临床动脉粥样硬化的患者间代谢控制的差异,采用logistic回归分析探讨亚临床动脉粥样硬化进展的危险因素。结果156例患者经2年的综合强化干预,颈总动脉和股动脉血管内中膜厚度与基线比较差异无统计学意义,但显著高于1年时的对应值(P＜0．01)；干预2年时,45例(28．8%)患者检出有血管内中膜厚度异常或动脉粥样硬化斑块,高于干预1年时的18例(11．5%,P＜0．01)；糖化血红蛋白、总胆固醇、高密度脂蛋白胆固醇、稳态模型的胰岛素抵抗指数与干预1年时的对应值比较有升高趋势(P＜0．01)；糖化血红蛋白的达标率亦显著低于干预1年时(P＜0．01)。亚临床动脉粥样硬化组糖化血红蛋白和低密度脂蛋白胆固醇的达标率低于无动脉粥样硬化组(P＜0．01)。logistic回归分析显示,低密度脂蛋白胆固醇达标可使亚临床动脉粥样硬化发生的相对危险度减少83%,糖化血红蛋白达标使相对危险度减少59%,但随访2年时,年龄每增加10岁使相对危险度增加82%。结论多因素强化干预并不能完全阻止新诊2型糖尿病亚临床动脉粥样硬化的发生,随着时间的推移,亚临床动脉粥样硬化呈进展趋势,血糖、血脂亦呈上升趋势；低密度脂蛋白胆固醇和糖化血红蛋白是否达标以及年龄是影响新诊2型糖尿病患者发生亚临床动脉粥样硬化的主要危险因素。更多还原

【Abstract】 Objective To investigate risk factors for the progress of subclinical atherosclerosis (AS)in newly diagnosed type 2 diabetics with muhifactorial intervention.Methods One hundred and fifty- six patients of type 2 diabetes,aged 35～70 years,with course of less than one year and without subclinical AS,were observed prospectively.After two-year intervention based on anti-platelet therapy integrated with intensive control of blood glucose,blood lipid,blood pressure and body weight,dynamic changes in all metabolic indicators and subclinical AS in the patients and differences between those with subclinical AS and without it were analyzed to study the risk factors for its progress by logistic regression analysis.Results There were no significant differences in intima-medial thickness(IMT)of common carotid artery(CCA) and femoral artery(FA)in the patients between baseline and two years after intervention,but those in them were significantly increased two years after intervention than those one year after intervention(P＜0.O1). Two years after intervention,increased IMT or atherosclerotic plaques could be found in 45 of 156 patients (28.8%),significantly higher than those one year after intervention(11.5%,P＜0.01).Levels of glycosylated hemoglobin Alc(HbAlc),total cholersterol(TC),high-density lipoprotein-cholesterol (HDL-C)and HOMA-insulin resistance(IR)showed an increased trend two years after intervention,as compared with those one year after intervention(P＜0.01).Proportions of those with normal level of HbAlc two years after intervention was significantly lower than that one year after intervention(P＜0.01). Proportions of those with normal level of HbAlc and low-density lipoprotein-cholesterol(LDL-C)were significantly lower in patients with subclinical AS than those without it two years after intervention(P＜0.01).Logistic regression analysis showed that relative risk(RR)for subclinical AS could reduce by 83% with normal level of LDL-C and 59% by normal HbAlc,respectively,but there was an 82% increase in RR for it with an increase of age by ten years.Conclusions Subclinical AS could not be absolutely prevented in patients with newly diagnosed type 2 diabetics after two-year intensive multifactorial intervention.Subclinical AS could present a progressive trend with time,as well as levels of blood glucose and blood lipid.Levels of LDL-C and HbAlc,as well as age,were major risk factors for occurrence of subclinical AS in patients with newly-diagnosed type 2 diabetes.更多还原
