目的 初步探讨双峰型胰岛素释放曲线(IRC)出现的原因.方法 以63例双峰型IRC2型糖尿病患者为双峰组、18名正常志愿者为对照组,进行口服葡萄糖耐量试验、胰岛素释放试验和C-肽释放试验,并计算稳态模型指标.结果 两组受试者的空腹血糖、空腹胰岛素、1 h胰岛素、空腹C-肽、1 h C-肽、Homa-1R差异无统计学意义;0.5 h血糖、1 h血糖、2 h血糖、3 h血糖、0.5 h胰岛素、2 h胰岛素、3 h胰岛素、0.5 hC-肽、2 h C-肽、3 hC-肽、血糖曲线下面积、胰岛素曲线下面积、C-肽曲线下面积、胰岛素分泌指数、△I30/△G30:双峰组>对照组,△C-P30/△G30:双峰组<对照组.结论 双峰组患者胰岛第一分泌相过度代偿,0.5 h胰岛素形成假性峰值而导致血糖增高,胰岛第二分泌相形成正常峰值,此组患者应为糖耐量受损.

Objective To investigate the reason for the appearance of bimodal insulin release curve (IRC). Methods Sixty-three cases of bimodal pattern of IRC (double hump group) were selected as experimental group; 18 normal volunteers as control group. Oral glucose tolerance test, insulin release test and C-peptide release test were performed, and the index of steady-state model was calculated. Results There were no significant difference among the two groups in fasting insulin, 1 hC-peptide, fasting plasma glucose, Homa-insulin resistance. 0.5 hIns: double hump group > control group. Fasting C-peptide: control 1 group >double hump group > normal Group. 0.5 h C-peptide: double hump group and control group >normal group. Fasting plasma glucose: normal group > double hump group and control group. 0.5 h plasma gulcose: normal group > double hump group > control group. glucose area under curve: normal group >double hump group > control group; △I30△ G30: double hump group > control group >normal group. insulin area under curve and C-peptide area under curve: double hump group > control group and normal group.There were significant difference among the results. Conclusions The pancreatic island has an overcompensation in the first secretion phase in double hump group, and the insulin displayed the pseudopeak value at 0.5 h which lead to the increase of blood glucose. The pancreatic island has a normal peak value in the second secretion phase, the patients in this group exsits impaired glucose tolerance.
