摘 要:目的 比较单纯空腹血糖受损(I-IFG)和单纯糖耐量受损(I-IGT)肥胖者的内皮功能及代谢异常的异同.方法 选择I-IFG(C组)60例(非肥胖即C1组28例,肥胖即C2组32例)和I-IGT(D组)83例(非肥胖即D1组41例,肥胖即D2组42例)作比较,以糖耐量正常者(N组)142例(非肥胖即N1组75例,肥胖即N2组67例)作对照,做口服葡萄糖耐量试验及胰岛素释放试验检测血糖、免疫活性胰岛素,同时检测空腹血脂、游离脂肪酸、脂联素、超敏C反应蛋白(hs-CRP)、内皮素(SET),留取晨尿测定内皮素(UET)、尿微量白蛋白(MUA).测量腰围、血压、身高和体质量.彩超测定肱动脉休息时、加压及服用硝酸甘油后的内径变化.计算平均动脉压(MAP)、血糖曲线下面积(glu AUC)、胰岛素曲线下面积(INSAUC)、第二相胰岛素曲线下面积(INSAUC two)、20 min胰岛素净增值与血糖净增值的比值(△I20/△G20)、β细胞功能指数(HOMA-β)和胰岛素抵抗指数(HOMA-IR)等.结果 校正性别、年龄后,D组和D1组的hs-CRP、SET和UET分别与C组和C1组比较差异有统计学意义(P <0.05或P<0.01),D2组与C2组hs-CRP比较差异有统计学意义(P<0.05);D组与C组比较空腹血糖(FPG)、糖耐量2h血糖(2 h PG)、glu AUC、HOMA-β、胰岛素释放试验2h胰岛素(INS120)和△I20/△G20差异均有统计学意义(P<0.05或P<0.01);D1组与C1组比较FPG、glu AUC、2 h PG、HOMA-IR、HOMA-β、INS120、INSAUC、INSAUC two、△I20/△G20,差异均有统计学意义(P <0.05或P<0.01);D2组与C2组比较MAP、FPG、HOMA-β、2hPG、INS120差异均有统计学意义(P<0.05).结论 I-IGT非肥胖者出现了大血管内皮功能损害且微血管内皮功能损害更严重,而肥胖者大血管内皮功能损害更严重;I-IFG肥胖者血压明显增高;I-IGT糖代谢紊乱较重、胰岛功能损害轻但非肥胖者早期相缺陷较重;I-IGT和I-IFG肥胖�Objective To compare the discursion of endothelial function and metabolism in obese isolated impaired fasting glucose (I-IFG) and isolated impaired glucose tolerance(I-IGT).Methods Sixty cases of I-IFG(group C) including obesity(group C2; 32 cases) and no-obesity (group C1; 28cases) and 83 cases of I-IGT (group D) including obesity (group D2 ; 42 cases) and no-obesity (group D1:41cases) were compared to 142 cases of normal glucose tolerance (group N) including obesity(group N2 ;67 cases) and no-obesity (group N1; 75 cases).All cases were detected glucose and insulin with oral glucose tolerance test and insulin release test.Fasting venous blood of all samples were obtained to measure the levels of fasting of blood lipids,free fatty acids (FFA),adiponectin (APN),high-sensitivity C-reactive protein (hs-CRP) and serum endothelin-1 (SET-1),and urine endothelin-1 (UET-1) and urea-microalbumin (MUA) after collecting urina sanguinis.To be measured waistline,blood pressure,height and weight,and the arteria brachialis diameter was tested at least and after arteria brachialis elevated pressure and glycergl trintrate.To calculate main arterial blood pressure (MAP),area under curve of glucose (glu AUC),area under curve of insulin (INSAUC),second-phase area under curve of insulin (INSAUC two),ratio of the net increment of insulin to plasma glucose at 20 min (△ I20/△ G20),insulin resistance index (HOMA-IR)and index of pancreatic islets secretion function (HOMA-β).Results It is significant difference between groups D and C,and between groups D1 and C1 in hs-CRP,SET,UET(P 〈0.05 orP 〈0.01) after adjusting sex and age.It is significant difference between groups D2 and C2 in Hs-CRP(P 〈0.05).Meanwhile between groups D and C in FPG,2 h PG,glu AUC,HOMA-β,INS120 and △I20/△G20 (P 〈0.05 or P 〈0.01),between groups D1 and C1 in FPG,glu AUC,2 h PG,HOMA-IR,HOMA-β,INS120,IN-SAUC,INSAUC two and △I20/△G20(P 〈
