摘要
目的 评估幽门螺杆菌 (Hp)感染对慢性胃炎胃黏膜环氧合酶 2 (COX 2 )表达的影响。 方法 与 10例正常对照者比较 ,用免疫组化方法半定量检测 46例慢性胃炎患者Hp根除治疗前后胃窦黏膜COX 2蛋白的表达 ,用悉尼分类标准对胃黏膜炎症、活动性和Hp密度进行半定量测定。 结果 在胃黏膜表面上皮、腺上皮细胞和固有层间质细胞的胞浆中可见COX 2表达。与正常对照者比较 ,Hp感染胃黏膜的COX 2平均阳性细胞率明显增加 [(18.0± 14.1) %比 (12 .3± 4.6 ) % ,P <0 .0 5 ) ];成功根除Hp后的胃黏膜COX 2平均阳性细胞率明显下降 [(2 0 .1± 13 .1) %比 (13 .8± 5 .9) % ,P <0 .0 5 ) ];COX 2表达与慢性炎症计分相关 (r =0 .78,P <0 .0 5 )。结论 Hp感染导致胃黏膜COX 2表达增加 ,提示COX 2在Hp相关性胃炎发生中起作用。
