摘  要:目的通过观察具有糖尿病的代谢综合征患者采用二甲双胍或吡格列酮治疗后血糖、胰岛素、胰高血糖素、胰岛β细胞功能和胰岛素抵抗的改变,探讨胰岛α细胞功能在以胰岛素抵抗为核心的2型糖尿病致病机制中的可能作用及其在药物治疗后的变化情况。方法于2012年4月至2013年4月在北京市朝阳区糖尿病中心选取具有糖尿病的代谢综合征患者60例,按随机数字表法分为二甲双胍组(口服二甲双胍0.5g/次,每日3次,n=30)和吡格列酮组(口服吡格列酮15mg/次,每日1次,n=30),治疗1年。同期选取年龄性别匹配的体检正常的健康人30例作为对照组。比较3组的一般资料及药物干预组治疗前后血糖、胰岛素、胰高血糖素、胰岛素敏感性指数、胰岛素抵抗指数、胰岛β细胞功能指数、胰岛素分泌敏感性指数、第1时相胰岛素分泌指数及第2时相胰岛素分泌指数。结果药物干预组治疗前与对照组比较,空腹胰高血糖素[(146.22±25.41)pmol/L比(21.31±7.85)pmol/L,P=0.002]及胰高血糖素曲线下面积均显著升高[(469.84±13.12)pmol/(L·h)比(100.94±7.73)pmol/(L·h),P=0.006]。二甲双胍组治疗后与治疗前比较,空腹血糖[(6.46±1.38)mmol/L比(7.54±0.43)mmol/L,P=0.031]、空腹胰岛素[(119.22±69.01)pmol/L比(139.38±71.13)pmol/L,P=0.042]、空腹胰高血糖素[(91.69±22.11)pmol/L比(142.81±24.56)pmol/L,P=0.029]、血糖曲线下面积[(25.19±1.31)mmol/(L·h)比(32.68±1.12)mmd/(L·h),P=0.043]、胰岛素曲线下面积[(468.65±20.10)pmol/(L.h)比(786.32±21.37)pmol/(L·h),P=0.017]和胰高血糖素曲线下面积[(280.60±8.26)pmol/(L·h)比(487.14±14.31)pmol/(L·h),P=0.032]均显著降低;吡格列酮组治疗后与治疗前比较�Objective To observe and evaluate the effects of metformin and pioglitazone on blood glucose, insulin, glucagon, β-cell function and insulin resistance among patients with diabetes and metabolic syndrome, so as to discuss the role of pancreatic α cells in pathogenesis of type 2 diabetes mainly caused by insulin resistance and the change of a-cell function after treatment. Methods A total of 60 patients diagnosed with diabetes and metabolic syndrome were selected in Beijing Chaoyang District Diabetes Center from April 2012 to April 2013 and divided with random number table into metformin group ( treated with metformin 0. 5 g orally thrice a day for 1 year, n =30) and pioglitazone group (treated with pioglitazone 15 mg orally once a day for 1 year, n =30). 30 normal healthy people who had physical examination at the Center during the same period were enrolled into the control group, matched in age and gender with the intervention groups. The general condition of the 3 groups, and blood levels of glucose, insulin, and glucagon, insulin sensitivity index (ISI) -Matsuda, homeostasis model as- sessment of insulin resistance (HOMA-IR), β-cell function index (HOMA-β), 1-phase index, 2-phase index, and insulin secretion sensitivity index (ISSI) at baseline in the 3 groups and after treatment in the metformin group and the pioglitazone group were measured and calculated. Results Compared with the control group be- fore treatment, the intervention groups as a whole had significantly higher fasting glucagon level [ ( 146. 22± 25.41 ) pmol/L vs. (21.31 ±7. 85) pmol/L, P =0.1302] and area under curve (AUC) of glucagon [ (469. 84 ± 13. 12) pmol/(L · h) vs. (100. 94 ± 7.73) pmol/(L · h), P = 0. 006 ]. Compared with the results before treatment, the metformin group exhibited significantly reduced fasting glucose [ (6.46 ± 1.38) mmol/L vs. (7. 54 ± 0.43) mmol/L, P= 0.031], fasting insulin [ (119.22 ± 69.01) pmol/L vs. (139.38 ± 71.13 ) pmol/L, P = 0.
