Abstract:To explore the effect of bifidobacterium quadruple viable tablet combined with quadruple therapy on serotransforming growth factor-1 (TGF-1), gastrin 17 (G17), and pepsinogen I (PGI) in patients with H.pylori (HP)-positive gastric ulcer. Methods98 patients with HP positive gastric ulcer were randomly divided into control group and combined group. The control group was treated with tetrad therapy, and the combined group was treated withtetrad therapy combined with bifidobacterium quadruple viable tablet. The clinical efficacy, gastric mucosal histological score, serum TGF-1, PGI, G17, gastrin (MTL), and adverse effects were compared between the two groups. ResultsThe total effrctiverate of the combination group was higher than control group (P<0.05). Compared with pre-treatment, the gastric mucosal histology scores, TGF-1, G17, and PGI were decreased,and MTLwasincreased, and the combination group was more significant than control group (P<0.05). The overall incidence of adverse effects in the combination group was lower than that in the control group (P<0.05). ConclusionBifidobacterium quadruple viable tablet combined with quadruple therapy has a satisfactory curative effect in the treatment of HP-positive gastric ulcer, and can regulate the level of gastrointestinal hormones, with good safety and clinical value.
