Abstract:

目的 探讨环氧化酶-2(COX-2)在幽门螺杆菌(Hp)感染与非感染性胃溃疡及胃癌的表达。方法 选择绵阳市404医院消化内科2011年2月-2012年2月的门诊及住院患者,用免疫组织化学方法检测196例经胃镜和组织病理学检查明确为胃溃疡(病理分型肠上皮化生、异型增生)、胃癌及正常胃黏膜者的胃黏膜COX-2蛋白的表达,比较各病理分类之间及Hp感染与非感染之间COX-2蛋白表达的差异。结果 胃溃疡(肠上皮化生、异型增生)、胃癌组的炎症细胞、腺上皮细胞、癌细胞及极少量正常黏膜上皮细胞中有COX-2表达。从正常胃黏膜-胃溃疡(肠上皮化生、异型增生)-胃癌COX-2的阳性表达有逐渐增强的趋势(P<0.05)。Hp阳性组COX-2的阳性表达高于Hp阴性组(P<0.05),胃癌组COX-2的阳性表达高于胃溃疡组(P<0.05)。结论 COX-2在胃癌的表达高于胃溃疡。Hp感染可诱导COX-2过度表达。
