摘 要:目的 探讨血管内皮生长因子(VEGF)及其受体FLT-1、FLK-1mRNA在门静脉高压性胃病(PHG)中的作用。方法 采用逆转录聚合酶链反应(RT-PER)对44例肝硬化门静脉高压症患者PHG动态变化过程中病变部位的VEGF、FLT-1及FLK-1mRNA的表达进行检测。结果 轻度胃病组VEGF、FLT-1、FLK-1mRNA的表达量分别为(2.28±0.33)、(0.59±0.17)和(0.56±0.14),与无胃病组及正常对照组比较差异均有显著性(均P〈0.01);重度胃病组VEGF、FLT-1、FLK-1mRNA分别为(3.48±1.02)、(0.68±0.20)和(0.71±0.18),与轻度胃病组、无胃病组及正常对照组比较差异均有显著性(均P〈0.01)。结论 VEGF及其受体FLT-1、FLK-1过度表达是胃病胃黏膜损害的重要因素之一。Objective To study the role of vascular endothelial growth factor ( VEGF ) and its receptor FLT-1,FLK-1 mRNA in the development of portal hypertensive gastropathy (PHG). Methods The expression of VEGF and its receptor FLT-1, FLK-1 mRNA in 44 patients with PHG were analyzed by reverse transcription-polymerase chain reaction (RT-PCR). Results VEGF and its receptor FLT-1, FLK-1 mRNA were all detected in the gastric mucosa, with higher level in the moderate PHG than the patients without PHG and the normal controls [ ( 2.28 ± 0.33 ), ( 0.59 ± 0. 17 ), ( 0.56 ± 0.14 ) P 〈 0.01 respectively]. The expression of VEGF and its receptor FLT-1, FLK-1 mRNA were higher in the severe PHG than the moderate PHG and the patients without PHG [ (3.48 ± 1.02 ) , (0.68 ± 0.20 ), (0.71 ± 0.18 ) P 〈 0.01 respectively ]. Conclusion The expression of VEGF and its receptor FLT-1 ,FLK-1 mRNA is up-regulated in the portal hypertensive gastric mucosa,which are one of the important factors in the development of PHG.
