摘要 目的探讨幽门螺杆菌感染、p53和血管内皮生长因子(VEGF)表达水平与胃癌发生、发展的关系;方法收集120例威海市立二院消化科行胃镜检查的门诊及住院患者的胃组织样本和血液样本,其中胃癌组78例,不典型黏膜组25例、正常黏膜组17例;分别采用病理WarrthinStarry银染和ELISA方法观察不同黏膜组织中幽门螺杆菌感染情况,免疫组化方法观察组织中p53和VEGF的表达情况;结果胃癌组、不典型黏膜组幽门螺杆菌感染、p53和VEGF阳性表达率均明显高于阴性患者(P<0.05),各组幽门螺杆菌感染阳性患者p53和VEGF阳性表达率明显高于阴性患者(P<0.05);结论胃癌与幽门螺杆菌感染存在一定相关性,p53和VEGF可调控细胞凋亡,对胃癌的发生、发展可能起到一定的促进作用。
