ObjectiveTo investigate the clinical curative effect of traditional Chinese medicineKuiyu decoction combined with quadruple therapy for peptic ulcer (PU).MethodsThis study was a randomized controlled trial. 82 patients with PU and conformed to the indusive criteria were randomly divided into a control group and a treatment group by the random number table method, with 41 cases in each group. The control group was treated with quadruple therapy, while the treatment group was treated with traditional Chinese medicineKuiyu decoction based on the treatment of the control group. Integral change of main symptoms before and after treatment and the level changes of serum motilin (MTL), somatostatin (SS) of the two groups before and after treatment were compared and clinical total effective rate was evaluated.ResultsThe total effective rate was 95.1% (39/41) in the treatment group and 80.5% (33/41) in the control group. There was statistical difference between the two groups(χ2=4.100,P=0.043). Stomach pain (0.58 ± 0.21vs.0.73 ± 0.28,t=2.744), gasteremphraxis (0.35 ± 0.12vs.0.43 ± 0.14,t=2.778), sour regurgitation integral (0.28 ± 0.09vs.0.34 ± 0.11,t=2.703) and serum MTL level (358.5 ± 81.3 pg/mlvs.422.8 ± 86.9 pg/ml,t=3.460) in the treatment group were lower than those in the control group (P<0.01);the serum SS level (87.5 ± 18.7 pg/mlvs.73.8 ± 17.9 pg/ml,t=3.389) in the treatment group was higher than that in the control group(P<0.01).ConclusionsTraditional Chinese medicineKuiyu decoction combined with quadruple therapy for the patients with PU can promote SS secretion through decreasing MTL, so it can improve the clinical effect.
