摘要
目的 :探讨 2型糖尿病 (DM)患者的肥胖子女与非肥胖子女的胰岛素分泌功能的 6个参数水平的变化。方法 :以 2型糖尿病患者的 2 3名非肥胖子女为A组 ,18名肥胖子女为B组 ,对照组用 2 7名健康体检者 ,行简化的口服葡萄糖耐量试验 (OGTT) ,测空腹血糖和胰岛素 ,服糖后 2h血糖和胰岛素 ,应用稳态模式胰岛素抵抗指标 (HOMA -IR)作为胰岛素抵抗指标 ,用稳态模式胰岛 β细胞功能指数 (HBCI)作为胰岛素分泌指标 ,对三组的这些指标进行对比分析。结果 :与对照组比较 ,A组空腹血糖相对升高 (P <0 0 5 ) ,HBCI降低 (P <0 0 5 ) ,B组空腹血糖升高 (P <0 0 5 ) ,服糖后 2h血糖升高 (P <0 0 5 ) ,HBCI降低 (P <0 0 1) ,HOMA -IR升高(P <0 0 5 )。结论 :2型DM患者的非肥胖子女在出现糖耐量减低前存在胰岛素分泌功能减退 ,肥胖子女减退更明显。
Objective To investigate the disturbance of insulin-secretion function in the offsprings of patients with type Ⅱ diabetes. Methods Blood sugar (with oxidase method) and insulin (with RIA) levels were measured after overnight fasting and repeatedly measued 2h after 75g glucose per oral in the following subjects: ① Group A, 23 non-obese offsprings of type Ⅱ diabetics ② group B, 18 obese offsprings (BMI≥25kg/m 2) and ③ 27 controls. Homeostatic model assessment-insulin resistance (HOMA-IR) and β-cell function index (HCI) were calculated from the data (glucose and insulin levels) obtained. Results For Group A subjects, the fasting blood sugar (FPG) levels were significantly higher and HBCI significantly lower than those in te controls (both P<0.05). For Group B obese subjects, in addition to the above two parameters (with HBCI P<0.01), 2h PG levels as well as HOMA-IR were also significantly higher (both P<0.05). Conclusion Present study showed that in the offsprings of diabetics, HBCI was already lowered before definite impaired glucose tolerance (IGT) could be demonstrated, especially in the obese ones.
