Abstract:Objective To observe the efficacy of Yiqi Huoxue Tongluo Formula combined with rabeprazole in treating chronic atrophic gastritis and its effect on serum levels of hypoxia-inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF) in patients, providing evidence for clinical treatment.Methods A total of 80 patients with chronic atrophic gastritis of the pattern of spleen-stomach qi deficiency and blood stasis obstructing collaterals, admitted to Suzhou Traditional Chinese Medicine Hospital Affiliated to Nanjing University of Chinese Medicine from January 2024 to June 2025, were randomly divided into an observation group and a control group using a random number table method, with 40 cases in each group. The control group received oral rabeprazole sodium enteric-coated tablets, while the observation group was treated with Yiqi Huoxue Tongluo Formula in addition to the treatment given to the control group. Both groups received continuous treatment for 12 weeks. The therapeutic efficacy, Traditional Chinese Medicine (TCM) syndrome scores, gastric mucosal pathology scores, HIF-1α and VEGF levels, and adverse reactions were compared between the two groups.Results The total effective rate was significantly higher in the observation group than in the control group (P < 0.05). After treatment, the scores for dull epigastric pain, abdominal distension and discomfort, poor appetite, and fatigue and weakness were significantly lower in the observation group than in the control group (all P < 0.05). Within the same group, the post-treatment scores for the above symptoms were significantly lower than the pre-treatment scores (all P < 0.05). After treatment, the scores for atrophy, intestinal metaplasia, and dysplasia were significantly lower in the observation group than in the control group (all P < 0.05). Within the same group, post-treatment pathological scores were significantly lower than the pre-treatment scores (all P < 0.05). After treatment, serum HIF-1α and VEGF levels were significantly lower in the observation group than in the control group (all P < 0.05). Within the same group, post-treatment HIF-1α and VEGF levels were significantly lower than pre-treatment levels (all P < 0.05). There was no statistically significant difference in the total incidence of adverse reactions between the two groups (P > 0.05).Conclusion Yiqi Huoxue Tongluo Formula combined with rabeprazole demonstrates significant efficacy in treating patients with chronic atrophic gastritis of the pattern of spleen-stomach qi deficiency and blood stasis obstructing collaterals. It improves TCM syndromes and gastric mucosal pathological status, reduces serum HIF-1α and VEGF levels, and does not increase adverse reactions.
