摘要: 目的:探讨血清中胃蛋白酶原(PG)、胃泌素17(G-17)和幽门螺杆菌抗体(anti-HP)检测应用于胃癌筛查的可行性,阐明其临床价值。方法:选择早期胃癌患者208例作为观察组,同期体检正常者208人作为空白对照组。利用酶联免疫吸附试验和乳胶增强免疫比浊法检测2组受试者血清中PGⅠ、PGⅡ和G-17水平;采用13C尿素呼吸试验检测2组受试者anti-HP阳性率,并对anti-HP阳性(anti-HP阳性组)和anti-HP阴性(anti-HP阴性组)受试者血清PGⅠ、PGⅡ水平和PGⅠ/PGⅡ比值进行比较分析。结果:与空白对照组比较,观察组患者血清PGⅠ/PGⅡ比值和PGⅠ水平明显降低(P<0.01),而PGⅡ、G-17水平和anti-HP阳性率明显升高(P<0.01);与anti-HP阴性组比较,anti-HP阳性组受试者血清PGⅠ/PGⅡ比值和PGⅠ水平明显降低(P<0.01),而PGⅡ和G-17水平明显升高(P<0.01)。结论:anti-HP阳性率结合PGⅠ/PGⅡ比值检测对于胃癌筛查具有重要的临床意义,提示上皮内瘤病变组织中G-17和PGⅡ水平可以作为胃癌前病变的观察指标。

Abstract: Objective:To investigate the feasibility of detection of serum pepsinogen (PG), gastrin-17 (G-17) and Helicobacter pylori antibody (anti-HP) in the gastric cancer screening, and to elucidate its clinical value. Methods:A total of 208 patients with early gastric cancer were selected as observation group; at the same time, 208 healthy examinees were regarded as blank control group. The levels of PGⅠ, PGⅡ and G-17 of the subjects in two groups were detected by enzyme-linked immunosorbent assay and latex-enhanced immunoturbidimetry; the positive rates of anti-HP were detected by 13C urea breath test; the serum levels of PG Ⅰ, PG Ⅱ and PG Ⅰ/PG Ⅱ ratio of the anti-HP positive subjects (anti-HP positive group) and anti-HP negative subjects (anti-HP negative group) were compared and analyzed. Results:Compared with blank control group, the serum PGⅠ/PGⅡ ratio and PGⅠ level of the subjects in observation group were significantly decreased(P<0.01), and the levels of PGⅡ,G-17and the positive rate of anti-HP were increased(P<0.01).Compared with anti-HP negative group, the serum PGⅠ/PGⅡ ratio and PGⅠ level of the subjects in anti-HP positive group were significantly decreased(P<0.01).The levels of PGⅡ and G-17 were significantly increased (P<0.01). Conclusion:The detection of positive rate of anti-HP combined with the ratio of PGⅠ/PGⅡ has important clinical significance in gastric cancer screening.The levels of G-17 and PG Ⅱ in the epithelial neoplasia lesion tissue can be used as indicators of gastric precancerous lesions.
