胃增生性息肉和胃底腺息肉患者血清胃功能指标及幽门螺杆菌感染情况的分析

目的分析比较胃增生性息肉和胃底腺息肉患者血清胃功能指标及幽门螺杆菌(Helicobacter pylori,Hp)感染情况.方法选取2017年12月至2018年12月于徐州医科大学附属医院行胃镜检查发现胃息肉且病理证实为胃增生性息肉和胃底腺息肉患者135例,其中增生性息肉组68例,胃底腺息肉组67例.采用免疫印迹法对两组患者血清Hp抗体[尿素酶A(urease A,UreA)、尿素酶B(urease B,Ure B)、细胞毒素相关蛋白(cytotoxin associated gene A, CagA)、空泡细胞毒素(vacuolating cytotoxin,VacA)]进行定性检测.选取慢性浅表性胃炎80例为对照组.酶联免疫吸附(enzymelinkedimmunosorbent assey,ELISA)法检测3组血清胃功能指标[胃蛋白酶原(pepsinogen,PG)Ⅰ、PG-Ⅱ、胃泌素-17(gastrin,G-17)],并计算PGⅠ、PGⅡ比值(PGⅠ and PGⅡ ratio,PGR).结果胃增生性息肉组血清PGⅡ(13.13(8.15,20.30)μg /L)、G17(8.44(3.72,27.17)pmol/L)水平高于对照组(9.16(5.56,15.14)μg /L与1.83(0.87,5.95)pmol/L)(P均<0.05),PGR水平低于对照组(P<0.05);胃底腺息肉组血清PGⅠ(120.12(86.72,174.70)μg /L)、PGⅡ(11.92(7.27,22.26)μg/L)、G17(5.68(1.79,14.65)pmol/L)水平高于对照组(101.32(79.17,131.33)μg /L、9.16(5.56,15.14)μg /L、1.83(0.87,5.95)pmol/L)(P 均<0.05);胃增生性息肉组血清 G17 (8.44 (3.72, 27.17)pmol/L)水平高于胃底腺息肉组(5.68(1.79,14.65)pmol/L)(P<0.05);胃增生性息肉组Hp感染率61.76%(42/68)高于胃底腺息肉组40.30%(27/67)(P<0.05),且以Ⅰ型Hp为主(P<0.05);胃增生性息肉组Hp阳性者血清PGⅡ、G17水平均高于Hp阴性者(P均<0.05);胃底腺息肉组Hp阳性与阴性者血清PGⅠ、PGⅡ、G17、PGR水平比较差异无统计学意义;胃增生性息肉组Hp Ⅰ型者血清PGⅠ、PGR水平高于Hp Ⅱ型者(P<0.05),胃底腺息肉组Hp Ⅰ型血清PGⅠ、PGⅡ、G17、PGR水平与Ⅱ型比较差异无统计学意义.结论胃增生性息肉、胃底腺息肉患者血清PG、G17水平高于慢性浅表性胃炎患者,胃增生性息肉患者较胃底腺息肉患者Hp感染率高且胃功能指标存在异常.
