摘要:

目的 探讨血清胃蛋白酶原(PG)Ⅰ、PGⅡ、PGⅠ/PGⅡ比值(PGR)、胃泌素17(G-17)在健康体检中的价值。方法 采用酶联免疫吸附试验(ELISA)检测1 872名表观健康者血清PGⅠ、PGⅡ、G-17水平,并计算PGR。分析性别、年龄与血清PGⅠ、PGⅡ、PGR、G-17的关系,以PG和G-17同时阳性作为筛查方案,比较其与胃镜检查结果的符合率。结果 表观健康人群男、女性之间血清PGⅠ水平、PGR差异均有统计学意义(P<0.001),而PGⅡ、G-17水平差异无统计学意义(P>0.05)。随着年龄的增长,PGⅠ和PGⅡ水平逐渐上升,而PGR则呈下降趋势。血清G-17在21~50岁时为平台期,50岁之后G-17水平逐渐上升。男、女性之间血清PG、G-17阳性率以及PG与G-17同时阳性的比例差异均无统计学意义(P>0.05)。G-17阳性率明显高于PG阳性率(P<0.001)。PG和G-17同时阳性的筛查方案与胃镜检查结果的阳性符合率为12.5%。结论 血清PG、G-17联合检测对胃相关疾病的筛查具有重要意义,适合在体检人群中推广。

Abstract:

Objective To investigate the roles of serum pepsinogen(PG)Ⅰ,PGⅡ,pepsinogenⅠ/pepsinogenⅡ ratio(PGR) and gastrin 17(G-17) in healthy examination. Methods The levels of serum PGⅠ,PGⅡ and G-17 were determined by enzyme-linked immunosorbent assay(ELISA) in 1 872 healthy subjects. PGR was calculated. The relations of serum PGⅠ,PGⅡ,PGR and G-17 with sex and age were evaluated. The results of the combined determination of serum PG and G-17 were compared those of gastroscopy. Results The levels of serum PGⅠand PGR had statistical significance between males and females(P<0.001),while the levels of PGⅡand G-17 had no statistical significance(P>0.05). The levels of serum PGⅠ and PGⅡ were increased with the increasing of ages,while PGR was decreased. Serum G-17 reached a plateau in 21-50 years old,while it was gradually increased after 50 years old. There was no statistical significance in the positive rates of serum PG and G-17 and the double positive rate of serum PG and G-17 between males and females(P>0.05),and the positive rate of serum G-17 was higher than that of serum PG(P<0.001). Compared with the results of gastroscopy,the positive coincidence rate of the combined determination of serum PG and G-17 was 12.5%. Conclusions The combined determination of serum PG and G-17 is important in the screening of gastric-related diseases,which can be applied in healthy examination.
