摘要 目的探讨幽门螺杆菌(Helicobacter pylori,Hp)感染对胃黏膜中核因子-κB(NF-κB)表达的影响。方法应用免疫组织化学方法检测NF-κB p65在21例Hp阴性慢性胃炎和48例Hp阳性慢性胃炎胃黏膜中的表达情况,用悉尼分类标准对胃黏膜慢性炎症、活动性和Hp密度进行半定量测定。结果NF-κB p65主要表达于胃黏膜上皮细胞,固有层炎性细胞也有不同程度的表达。Hp阳性慢性胃炎胃黏膜中NF-κB p65的表达明显高于Hp阴性组(P<0.01),且NF-κB p65的表达与胃黏膜慢性炎症及活动性的程度相关(P<0.05)。结论Hp感染导致胃黏膜NF-κB p65表达增加,提示NF-κB参与了Hp相关性胃炎的病理生理过程。
