Abstract:Objective:To study the effect of auxiliary treatment of Banxia Xiexin decoction combined with domperidone in treating functional dyspepsia. Method: Eighty patients with functional dyspepsia were enrolled and divided into observation group and control group. Patients in observation group received auxiliary treatment of Banxia Xiexin decoction combined with domperidone. Patients in control group received domperidone alone. Then the therapeutic effect, clinical symptoms, plasma motilin level and psychological state between two groups were compared. Result: The total effective rate in observation group (90%) was significantly higher than that in control group (P<0.05). The abdominal pain, abdominal distention, acid regurgitation, belching scores in observation group were (0.72±0.06), (1.64±0.08), (0.62±0.08) and (0.95±0.04) respectively, which were lower than control group (P<0.05). The plasma motilin of (398.68±120.14) μg · L-1 in observation group was significantly higher than control group (P<0.05). The somatization score, obsessive-compulsive symptoms score, interpersonal sensitivity score, depression symptom scores, anxiety symptoms score, hostile score, terror symptom score, paranoid symptoms score in observation group were significantly lower than those in control group (P<0.05). Conclusion: Using Banxia Xiexin decoction combined with domperidone is helpful to improving clinical symptoms, promoting level high expression of plasma motilin, alleviating negative emotions and improving effect of treatment.
