摘要
目的研究幽门螺杆菌(Helicobacter pylori,H.pylori)感染者血清中TNF-α、IL-8、VEGF水平及其与胃炎病理组织严重程度的关系。方法选取2012年1月-2014年12月在延安大学附属医院行内窥镜确诊的80例慢性胃炎患者为研究对象,以13C尿素呼气和胃黏膜组织活检进行H.pylori检测。依据胃炎组织病理类型分为:慢性胃炎、中性粒细胞浸润、胃萎缩和肠上皮化生四个类别,检测患者血清中TNF-α、IL-8、VEGF的水平并分析其与慢性胃炎患者严重程度的关系。结果 80例胃炎患者中41.5%伴有H.pylori感染,且H.pylori感染者血清中TNF-α水平(4.34±3.72)pg/ml和VEGF水平(683.18±428.37)pg/ml明显高于未感染者(2.76±1.51)pg/ml和(485.26±306.75)pg/ml,差异有统计学意义(P<0.05);但IL-8水平在感染者与未感染者之间差异无统计学意义(P>0.05)。血清中TNF-α和IL-8水平与慢性胃炎严重程度密切相关,而血清中IL-8水平同时与中性粒细胞浸润程度密切相关,血清中VEGF水平则与萎缩性胃炎和肠上皮化生密切相关。结论血清中高TNF-α水平与慢性胃炎严重程度相关,高IL-8水平与慢性胃炎和中性粒细胞浸润相关,高VEGF水平则与胃癌癌前病变有关。
