摘要 [目的]探讨血清胃蛋白酶原(PG)、PGⅠ/PGⅡ比值以及血清促胃液素水平的表达与慢性萎缩性胃炎(CAG)的关系及意义。[方法]收集我院消化内科在知情同意前提下行智能染色内镜(i-Scan)检查符合研究标准的患者138例,内镜下收集黏膜活检标本,根据病理诊断结果分为CAG及非CAG组;应用时间分辨荧光免疫法测定血清PG水平,并计算PGⅠ/PGⅡ比值;酶联免疫法测定促胃液素水平;采用14 C呼吸试验和病理组织检查2种方法联合判断幽门螺杆菌(Hp)的感染情况。[结果]CAG组与非CAG组相比,血清PGⅠ水平降低、促胃液素值明显下降(均P<0.05),PGⅠ/PGⅡ比值2组比较差异无统计学意义。不同萎缩部位的CAG其PGⅠ及促胃液素值比较差异有统计学意义,胃窦萎缩者的PGⅠ要高于其他部位(P<0.05),胃体萎缩的促胃液素水平要高于其他部位(P<0.05)。[结论]检测血清PG及PGⅠ/PGⅡ比值和促胃液素水平,可以应用于CAG的临床筛查,根据有无异常,再行胃镜检查有助于提高CAG的检出率。Hp感染可以影响CAG PG的水平。
