Objective：To observe the clinical effect of Banxia Xiexin tang combined with triple therapy for chronic atrophic gastritis.M e th o d s：Selected 90 cases of patients with chronic atrophic gastritis of intertwined cold and heat type，and divided them into the control group and the observation group randomly，45 cases in each group.The control group was given amoxicillin capsules，rabeprazole sodium enteric-coated capsules and colloidal bismuth subcitrate capsules for treatment，while the observation group was additionally given Banxia Xiexin tang based on the syndrome differentiation for treatment.The treatment for both groups lasted for 8 weeks.Observed the changes of clinical symptoms and levels of superoxide dismutase(SOD)and malondialdehyde(MDA)in serum of both groups，and statistically analyzed the negative rates of helicobacter pylori(Hp)in both groups and the clinical effect.Results：The total effective rate was 93.3%in the observation group and 73.3%in the control group，difference being significant(P＜0.05).Each score of distention and pain in the epigastrium，distention and irritancy，low food intake and loss of apetite as well as epigastric upset and acid regurgitation in both groups were lower than those before treatment，differences being significant(P ＜ 0.05)；the four scores in the observation group were lower than those in the control group，differences being significant(P＜0.05).The clearance rate of Hp was 91.1%in the observation group and 71.1%in the control group，difference being significant(P＜0.05).The levels of SOD in both groups were higher than those before treatment，and the levels of MDA were lower than those before treatment，differences being significant(P ＜ 0.05)；the level of SOD in the observation group was higher than that in the control group，and the level of MDA was lo w e r than that in the control group，differences being significant(P ＜ 0.05).Conclusion：Banxia Xiexin tang combined with trip letherapy for chronic atrophic gastritis can significantly improve the clinical symptoms of patients，and promote the negative rate of Hp as well as the clinical effect.
