Objective To investigate the clinical efficacy of trimebutine combined with Xiangsha Pingwei in the treatment of functional dyspepsia and its effect on gastrointestinal hormone.Methods One hundred and twenty cases of functional dyspepsia were randomly divided into the control group and observation group,60 cases in each group.The control group was treated with trimebutine 0.2 g,3 times/d and the observation group was treated with trimebutine 0.2 g,3 times/d and Xiangsha Pingwei 10 g,2 times/d.Both groups were treated for four weeks,a course of treatment.Clinical efficacy and the influence on gastrointestinal hormone levels were compared between the two groups.Results The symptoms scores in both groups all decreased significantly after treatment.While the postprandial fullness scores,early satiety scores and epigastric pain scores in the observation group were significantly lower than those in the control group (0.62±0.12 vs.1.85±0.25,0.56±0.14 vs.1.46±0.21,0.48±0.15 vs.1.32±0.12,t=34.36,27.62,33.87,P<0.05).The total effective rate in the observation group was significantly higher than that in the control group (90.00% vs.73.33%,χ2=5.57,P<0.05).MOT and GAS levels in both groups increased significantly.While MOT and GAS levels in the observation group were significantly higher than those in the control group (MOT: (355.2±78.1) ng/L vs.(288.7±82.4) ng/L;GAS:(96.5±17.6) ng/L vs.(88.4±16.0) ng/L,t=4.54,2.64,P<0.05).The somatostatin (SS) level in both groups decreased significantly.While the SS level in the observation group was significantly lower than that in the control group ((41.1±11.1) ng/L vs.(48.9±12.9) ng/L,t=3.55,P<0.05).Conclusion Trimebutine combined with Xiangsha Pingwei can significantly improve the clinical symptoms and gastrointestinal hormone in patients with functional dyspepsia.
