对30例老年2型糖尿病患者及10例健康老年人空腹及标准脂肪餐后2h,4h,6h,8h胰岛素及C肽水平进行同步测定并加以分析。结果各时点胰岛素,老年糖尿病组高于对照组,空腹,餐后6h及8h统计学上有显著差异(P<0.05);老年糖尿病组各时点C肽水平低于对照组,有显著差异(P<0.05)。结论老年2型糖尿病患者标准脂肪餐后胰岛素及C肽分泌试验出现分离现象,即出现高胰岛素低C肽现象,为今后2型糖尿病患者使用C肽治疗奠定理论基础。
The levels of insulin and C-peptide in fasting and standard fat at 2h, 4h, 6h, 8h postprandial in 30 elderly patients with type 2 diabetes mellitus and 10 healthy controls were measured and analyzed simultaneously. Results The levels of insulin and senile diabetes mellitus in each group were higher than those in the control group at each time point (P <0.05), fasting and postprandial 6h and 8h postprandial (P <0.05). The levels of C-peptide in the elderly diabetic group were significantly lower than those in the control group (P <0.05). Conclusion Separation of insulin and C-peptide in postprandial insulin of type 2 diabetes mellitus in elderly patients with type 2 diabetes shows the phenomenon of high C-peptide with high insulin, which lays the theoretical foundation for the future use of C-peptide in type 2 diabetic patients.
