摘要
目的::探讨胃蛋白酶原Ⅰ(P GⅠ)和胃蛋白酶原Ⅱ(P GⅡ)检测对胃溃疡患者的筛查作用。方法:选取2013年1月-10月在青浦中心医院的体检者2052例,胃溃疡患者120例,分别检测血清P GⅠ和P GⅡ,并计算P GⅠ/P GⅡ比值,统计学分析三个指标在体检者与胃溃疡患者之间的差异。结果:胃溃疡患者血清PGⅠ、PGⅡ和PGⅠ/PGⅡ分别为316.7±129.2ng/ml、40.2±30.1ng/ml 和12.0±4.9,三者均显著高于体检人群(156.0±63.8ng/ml,15.9±11.1ng/ml 和9.7±4.3)(P<0.05)。如果以体检人群95%的可信区间设定正常参考值,则PGⅠ、PGⅡ和PGⅠ/PGⅡ的参考值分别为<270.9ng/ml、<37.8n g/m l和<14.4,它们对胃溃疡的阳性预期值分别为61.7%、55.8%和13.3%。结论:胃溃疡患者血清P GⅠ和P GⅡ水平均显著高于体检者,因此它们可能用于大规模人群胃溃疡的筛查。
Abstract
Objective: To investigate the screening effect of pepsinogenⅠ (PGⅠ) and epsinogenⅡ(PGⅡ) detection on gastric ulcer patients. Methods: 2052 physical examination population and 120 gastric ulcer patients were selected for PGⅠand PGⅡ detection in XXX hospital,from January 2011 to October 2011. Results: Serum PGⅠ, PGⅡ, and PGⅠ/PGⅡ in physical examination population were 316.7±129.2ng/ml, 40.2±30.1ng/ml, and 12.0±4.9, respectively. Each was significantly higher than those in gastric ulcer patients (156.0±63.8ng/ml, 5.9±11.1ng/ml, and 9.7±4.3,respectively.)(P<0.05). If PGⅠ<270.9 ng/ml as a reference, Positive expectations to gastric ulcer was 61.7%; PGⅡ<37.8ng/ml as a reference, Positive expectations to gastric ulcer was 55.8%; PGⅠ/PGⅡ<14.4 as a reference, Positive expectations to gastric ulcer was 13.3%. Conclusion: Serum PGⅠ and PGⅡ in gastric ulcers was significantly higher than those in physical examination population. Therefore, they may be useful in screening of gastric ulcer patients in large populations.
