摘要
目的:对比胃束带术(GB)、Roux-en-Y胃转流术(RYGBP)及胆胰分流术(BPD)治疗2型糖尿病(T2DM)大鼠的疗效。方法:通过注射链脲佐菌素(STZ)及喂饲高糖高脂饲料建立T2DM大鼠模型。将成功选模的70只大鼠分为GB组(G组)、RYGBP组(R组)、BPD组(B组),每组20只,另假手术组(S组)10只。检测术前及术后1、2、3、4、8、16周空腹血清葡萄糖(BG)、甘油三酯(TG)、总胆固醇(TC)、胰岛素(INS)含量,计算胰岛素敏感指数(ISI),观察术后各组死亡率和并发症。结果:术后第16周,GB组、RYGBP组、BPD组的空腹体重分别为(324.4±22.5)g、(338.9±17.5)g、(333.3±28.4)g,BG含量分别为(12.44±1.29)mmol·L-1、(9.70±0.81)mmol·L-1、(11.93±2.39)mmol·L-1,TC含量分别为(2.32±0.45)mmol·L-1、(2.22±0.79)mmol·L-1、(2.13±0.31)mmol·L-1,TG含量分别为(1.38±0.32)mmol·L-1、(1.16±0.41)mmol·L-1、(1.23±0.35)mmol·L-1,ISI分别为(-6.38±0.29)、(-6.67±0.24)、(-6.65±0.23),与术前比较,差异均有统计学意义(P<0.05,P<0.01),RYGBP组INS含量为(69.43±18.73)mU·L-1,与术前比较,差异有统计学意义(P<0.05)。GB组死亡率为5%,RYGBP组死亡率为20%,BPD组死亡率为35%。结论:GB、RYGBP、BPD均有降血糖、降血脂作用,对胰岛素抵抗(IR)有明显的改善作用。
This study was aimed to compare the efficacy of gastric banding(GB),Roux en-Y gastric bypass(RYGBP) and biliopancreatic diversion(BPD) in the treatment of rats with type 2 diabetes mellitus(T2DM).Animal models of T2DM were induced by streptozotocin(STZ) injection and high-sugar-fat diets.A total of 70 T2DM rats were randomly allocated into the GB group(G group,n = 20),RYGBP group(R group,n = 20),BPD group(B group,n = 20),and the sham operation group(S group,n = 10).The fasting blood glucose(BG),triglyceride(TG),total cholesterol(TC) and insulin(INS) content were determined before and 1,2,3,4,8,16 weeks after operation.The insulin sensitivity index(ISI) was calculated.The mortality and complications were observed in each group.The results showed that the fasting weight of the GB group,RYGBP group and BPD group were(324.4 ± 22.5) g,(338.9 ± 17.5) g,(333.3 ± 28.4) g,respectively.The BG content was(12.44 ± 1.29) mmol/L,(9.70 ± 0.81) mmol/L,(11.93 ± 2.39) mmol/L,respectively.The TC content was(2.32 ± 0.45) mmol/L,(2.22 ± 0.79) mmol/L,(2.13 ± 0.31) mmol/L,respectively.The TG content was(1.38 ± 0.32) mmol/L,(1.16 ± 0.41) mmol/L,(1.23 ± 0.35) mmol/L,respectively.The ISI were(-6.38 ± 0.29),(-6.67 ± 0.24),(-6.65 ± 0.23),respectively.And the INS content of the RYGBP group were(69.43 ± 18.73) mU/L.There were significant differences between before and after operation on the 16th week(P〈0.05,P〈0.01).The mortality rate was 5% in the GB group,20% in the RYGBP group,and 35% in the BPD group.It was concluded that the GB,RYGBP and BPD are effective in reducing blood glucose and blood lipids in the treatment of rat with T2DM.The treatment effect is obvious in the improvement of insulin resistance(IR).
