Objective: To observe the clinical effects of Jianwei Yuyang Granule (JYG) in treating patients with gastric ulcer and its influence on interleukin-1beta (IL-1beta) and basic fibroblast growth factor (bFGF) mRNA expression in gastric mucosa for exploring the therapeutic mechanism.
Methods: Fifty-six patients with confirmed gastric ulcer unader gastroscope and differentiated as Gan-stagnant Pi-deficient syndrome were randomly assigned to two groups, the treated group (26 cases) treated with JYG and the control group (30 cases) treated with famotidine and sucralfate, 4 weeks as one therapeutic course. The changes before and after treatment in clinical compliance, symptom integral, ulcer-healing rate, clinical effective rate, and HP-clearance rate were observed. And the gastric mucosa biopsy was fetched for morphological examination and IL-1beta and bFGF mRNA expression detection by RT-PCR as well.
Results: The clinical compliance rate in the treated group was 100 %, which was obviously better than that in the control group (86.7 %, P< 0.01); the improvement on symptom integral in the former was also better (P < 0.01); no statistical significance was shown in ulcer-healing rate, clinical effective rate and HP-clearance rate between the two groups. Morphological observation showed markedly decreased inflammatory cell infiltration, epithelial cell regeneration and rather regular glandular arrangement in both groups. The IL-1beta mRNA expression level decreased and that of bFGF increased in both groups after treatment significantly ( P < 0.01), but showed insignificant difference between the two groups.
Conclusion: JYG, with its good clinical compliance, has favorable effects in relieving clinical symptoms, promoting endoscopic ulcer healing and HP clearance, decreasing the expression of IL-1beta mRNA and increasing the expression of bFGF, therefore, it could promote the recovering of gastric ulcer.
