Objective： To observe the clinical efficacy of umbilical compress therapy of modified Banxia Xiexin Decoction combined with conventional western medicine in the treatment of acute duodenal ulcer bleeding.,Methods,2,Ninety patients of acute duodenal ulcer bleeding were randomly divided into the control group and treatment group， 45 cases in each group. The patients in the control group were treated with conventional western medicine， and the patients in the treatment group were treated with umbilical compress therapy of modified Banxia Xiexin Decoction based on the treatment for the control group， with a course of 5 days. The clinical efficacy was observed， and the changes of turning negative time of fecal occult blood， fasting time， hospital stay， traditional Chinese medicine syndrome score， hemoglobin level and blood urea nitrogen level were compared.,Results,2,①The apparent effective rate， effective rate and improvement rate of total syndrome score in the treatment group were higher than those in the control group （,P,<,0.05）. ②The turning negative time of fecal occult blood in the treatment group was earlier than that in the control group， and the fasting time was shorter than that in the control group （,P,<,0.05）. There was no statistically significant difference in the hospital stay between the two groups （,P,>,0.05）. ③ After treatment， the levels of hemoglobin and urea nitrogen in both groups were improved （,P,<,0.05）， and the improvement in the treatment group was better than that in the control group （,P,<,0.05）.,Conclusion,2,Compared with conventional western medicine alone， umbilical compress therapy of modified Banxia Xiexin Decoction combined with conventional western medicine shows good efficacy in the treatment of acute duodenal ulcer bleeding， which can be widely used in clinic.
