目的 探討以Goto-Kakizaki (GK)大鼠建立保留全胃的十二指腸空腸曠置術(shù)(DJB)模型的可行性及操作要點(diǎn)。
方法 將16只GK大鼠隨機(jī)分為實(shí)驗(yàn)組(n=8)和對(duì)照組(n=8)。在規(guī)范的術(shù)前、術(shù)中及術(shù)后操作下,對(duì)實(shí)驗(yàn)組和對(duì)照組大鼠分別行DJB術(shù)和假手術(shù),比較2組大鼠術(shù)前,術(shù)后1、2、3及4周空腹血糖和體質(zhì)量的變化情況,評(píng)價(jià)手術(shù)造模是否成功,并觀察2組大鼠的存活情況。
結(jié)果 術(shù)后4周2組大鼠均全部存活。與術(shù)前比較,實(shí)驗(yàn)組術(shù)后1周空腹血糖即下降(P<0.05),術(shù)后2、3及4周血糖趨于穩(wěn)定;對(duì)照組術(shù)后各時(shí)相空腹血糖水平無(wú)明顯變化(P>0.05)。術(shù)后各時(shí)相實(shí)驗(yàn)組的空腹血糖水平均低于對(duì)照組(P<0.05),提示成功建立了模型。實(shí)驗(yàn)組術(shù)后4周體質(zhì)量的增加值低于對(duì)照組(P<0.05)。
結(jié)論 DJB是一種可行的、安全有效的降糖術(shù)式。規(guī)范實(shí)驗(yàn)操作程序可以降低術(shù)中風(fēng)險(xiǎn),建立穩(wěn)定的GK大鼠DJB模型。
