Effect and Mechanism of Flavored Tongxie Yaofang Decoction for Diarrheal Irritable Bowel Syndrome under Intestinal Microecology

Abstract

This research was to analyze the effect of flavored Tongxie Yaofang on diarrheal irritable bowel syndrome (IBS) by the situation of intestinal microecology. The treatment mechanism was analyzed, so as to provide a more effective treatment method for patients clinically. 60 IBS patients were selected as the research objects and were divided according to the different treatment methods. For the control group (n = 20 cases), oral pinaverium bromide tablets were given. For the treatment group (n = 40 cases), the flavored Tongxie Yaofang decoction was given in addition to conventional treatment. The curative effects on the two groups of patients were evaluated in combination with the changes in intestinal microecology. With the syndrome score, the total effective rate of the treatment group (92.5%) was obviously superior to the control group (80%) ( $P<0.05$ ). The clinical symptoms such as abdominal pain, abdominal distension, and diarrhea in the treatment group were significantly relieved after treatment in contrast to the control group ( $P<0.05$ ). Intestinal Bifidobacterium, Escherichia coli, and Bifidobacterium/Escherichia coli (B/E) ratio were all greatly higher than those in the control group ( $P<0.05$ ). In summary, flavored Tongxie Yaofang had a good effect in improving the symptoms of patients with diarrheal IBS and improved the microflora of Bifidobacterium and Escherichia coli in the intestinal tract of patients.
