RESUMO
Objective To study the value of 4‐item examination of gastric function in the evaluation of disease severity and course of peptic ulcer .Methods The 4‐item examination of gastric function ,including PGⅠ ,PGⅡ ,PGⅠ /PGⅡ ,gastrin 17 and He‐licobacter pylori(Hp) positive rate ,were detected by adopting enzyme linked immunosorbent assay (ELISA) in 175 cases of peptic ulcer(study group) and 60 persons undergoing physical examination(control group) .The Spearman correlation coefficient was used to analyze the relationship between the 4‐item gastric function examination with the severity and course of peptic ulcer .Results The levels of PGⅠ ,PGⅡ ,gastrin 17 and Hp positive rate in the study group were significantly higher than those in the control group(P<0 .05) ,while PGⅠ /PGⅡwas significantly lower than that in the control group(P<0 .05) .The values of PG Ⅰ /PGⅡfrom high to low were in turn the scarring stage group ,healing stage group and active stage group ,other indexes from high to low were in turn active stage group ,healing stage group and scarring stage group .The levels of PGⅠ ,PGⅡand gastrin 17 and Hp posi‐tive rate in the patients with disease course ≥3 years were significantly higher than those in the patients with disease course<3 years(P<0 .05) .The severity and disease course in the patients with peptic ulcer were positively correlated with the levels of PGⅠ ,PGⅡ ,gastrin 17 and Hp positive rate(P<0 .05) and negatively correlated with PG Ⅰ /PGⅡ(P<0 .05) .Conclusion In the pa‐tients with peptic ulcer ,4‐item gastric function examination is closely correlated with the severity and course of illness ,which can serve as the index for evaluate the severity and course of disease ,thus increases the clinical treatment pertinence ,reduces the occur‐rence of antibacterial drugs abuse ,and is worthy of being promoted and applied in clinic .
