Clinical study on self-made Jianpi-Tiaogan-Wenshen decoction in the treatment of diarrhea-predominant irritable bowel syndrome / 国际中医中药杂志

ABSTRACT

Objective@#To evaluate the efficacy of self-made Jianpi-Tiaogan-Wenshen decoction in the treatment of diarrhea-predominant irritable bowel syndrome (IBS).@*Methods@#A total of 107 patients with diarrhea- predominant IBS who met the inclusion criteria were divided into control group (53 cases) and observation group (54 cases) by random number table method. On the basis of routine treatment, the control group was given Bifidobacterium triple viable powder and trimebutine maleate dispersible tablets, while the observation group was given self-made Jianpi-Tiaogan-Wenshen decoction. Both groups were treated for 4 weeks. The symptoms and signs were scored before and after treatment. The level of 5-hydroxytryptamine (5-HT) was measured by double antibody sandwich method. The mast cell count was observed under high power microscopy, and the clinical efficacy was evaluated.@*Results@#The total effective rate was 90.7% (49/54) in the observation group and 60.4% (32/53)in the control group, and there was significant difference between the two groups (χ2=13.406, P<0.01). After treatment, the levels of mast cell count (10.03 ± 2.19 pcs/Hp vs. 14.85 ± 1.98 pcs/Hp, t=11.935), 5-HT (7.06 ±1.37 mg/L vs. 9.67 ± 1.31 mg/L, t=10.069) significantly decreased in the observation group (P<0.05). After treatment, the VAS score, stool frequency score and stool character score of the observation group were significantly lower than those of the control group (t=11.560, 11.957, 20.539, respectively, P<0.05).@*Conclusions@#Self-made Jianpi-Tiaogan-Wenshen decoction can improve clinical symptomsof diarrhea-predominant IBS patients, reduce mast cell count and 5-HT level, and improve the clinical efficacy.
