摘  要:目的 分析影响Goto-Kakizaki(GK)大鼠Roux-en-Y胃旁路术后降糖效果的相关因素.方法 回顾性分析GK大鼠术前(0周)、术后1、3、6、12、24周摄食量、体质量、空腹血糖及术前(0周)、术后4、12、24周各时间点糖化血红蛋白(HbAlc)水平,探讨影响胃旁路术后降糖效果的相关性因素.依据术前HbAlc水平将GK大鼠分为A组,HbAlc 6.5%~7.9%;B组,HbAlc 8.0%~9.9%;C组,HbAlc> 10%,以评估术前HbAlc水平与胃旁路术后降糖效果之间的相关性.结果 与术前相比,大鼠术后1~24周空腹血糖、HbAlc均明显下降(P<0.01),术后24周时空腹血糖由(12.1 ±3.0)mmol/L下降到(7.6±1.3)mmol/L,HbAlc由(9.2%±1.8%)下降到(6.3%±0.8%).治愈组与好转组相比,术前空腹血糖分别为(11.1±2.2)、(15.8±2.3)mmol/L,HbAlc分别为(8.6%±1.4%)、(11.5%±1.4%),两组之间相比差异有统计学意义(均P<0.01),而两组大鼠术前摄食量及体质量之间相比差异无统计学意义(P>0.05).非条件Logistic逐步回归分析显示术前HbAlc对该手术的治愈率与好转率有预测价值(P<0.01).A组与C组、B组与C组降糖效果相比差异有统计学意义(P<0.01),而A组与B组相比差异无统计学意义(P>0.05).结论 GK大鼠术前HbAlc水平与胃旁路术后降糖效果具有相关性,且术前HbAlc< 10%时降糖效果较好.Objective To analyze the related factors associated with the effect of Roux-en-Y gastric bypass in Goto-Kakizaki rats.Methods In GK rats undergoing Roux-en-Y gastric bypass,the weight,food intake,and the fasting blood glucose were retrospectively analyzed before surgery and 1,3,6,12,24 weeks after surgery,and the glycosylated haemoglobin concentrations were retrospectively analyzed before surgery and 4,12,24 weeks after surgery.According to preoperative glycosylated haemoglobin concentrations,GK rats were divided into 3 groups(group A,HbAlc 6.5%-7.9%; group B,HbAlc 8.0%-9.9% ; group C,HbAlc 〉 10%).Results The fasting blood glucose and the glycosylated haemoglobin concentrations significantly decreased 1 week after surgery(P 〈 0.01),on 24 weeks after operation,the fasting blood glucose levels decreased from(12.1 ± 3.0)mmol/L to(7.6 ± 1.3)mmol/L,and the glycosylated haemoglobin concentrations declined from(9.2% ± 1.8%)to(6.3% ± 0.8%).Preoperative fasting blood glucose was(11.1 ± 2.2)mmol/L and(15.8 ± 2.3)mmol/L respectively,and the preoperative glycosylated haemoglobin concentration was(8.6% ± 1.4%)and(11.5% ± 1.4%)respectively(P 〈 0.01).Non-conditional Logistic regression analysis identified preoperative glycosylated haemoglobin concentrations as an independent predictor for the cure rate(P 〈 0.01); Differences were significant between group A and group C,and group B and group C on the efficiency of the surgery(P 〈0.01).Conclusions Significant correlation established between glycosylated haemoglobin concentrations and the efficiency of the surgery,especially for those rats with preoperative HbAlc 〈 10%.
