Abstract: 目的:研究断流术和分流术对门脉高压性胃病(PHG)大鼠胃粘膜细胞Caspase-3 mRNA表达的影响.方法:将48只Wistar雄性大鼠随机分成正常对照组、模型对照组、断流术组和分流术组.应用逆转录PCR(RT-PCR)测Caspase-3 mRNA表达.结果:正常对照组自由门脉压为(1.15±0.13)kPa,模型对照组升高至(2.68±0.16)kPa(P<0.01),断流术组升高达(2.73±0.27)kPa,分流术组回降至(1.57±0.23)kPa,与模型对照组比较差异有统计学意义(P<0.01).Caspase-3 mRNA表达有类似变化,正常对照组、模型对照组、断流术组和分流术组各组表达分别为0.48±0.02、0.96±0.04、1.04±0.06和0.65±0.03.结论:正常鼠胃粘膜上皮细胞凋亡基因Caspase-3 少量表达,PHG时Caspase-3 mRNA表达增加,断流术后Caspase-3 mRNA表达进一步上调,分流术后Caspase-3 mRNA表达有所下调.
