Abstract
OBJECTIVE: To observe the effect of acupuncture-moxibustion on negative emotions and plasma tryptophan (Trip)-kynurenine (Kyn) metabolism in the patients with Crohn's disease (CD) at the mild and moderate active stage. METHODS: A total of 66 CD patients were randomized into an observation group (33 cases, 1 case dropped off) and a control group (33 cases, 2 cases dropped off). In the observation group, acupuncture was applied in combination with moxibustion. In the control group, the sham-acupuncture was used in combination with sham-moxibustion. In both of the observation group and the control group, acupuncture was applied to Zhongwan (CV 12), Shangjuxu (ST 37), Sanyinjiao (SP 6), Gongsun (SP 4), Hegu (LI 4), Quchi (LI 11), Taixi (KI 3) and Taichong (LR 3), and moxibustion was applied to Tianshu (ST 25) and Zusanli (ST 36). The treatment was given once every two days, 3 times a week, totally for 12 weeks. Separately, before and after treatment, the score of the hospital anxiety-depression scale (HADS) and the score of intestinal core symptoms (degree of abdominal pain and frequency of diarrhea) were observed in the patients of the two groups. The concentration of plasma indoleamine 2,3-dioxygenase 1 (IDO1) and the ratios of Kyn/Trp, QuinA/Kyn, KynA/Kyn and KynA/QuinA were compared between the two groups. RESULTS: Compared with before treatment, the scores of HADS-A and HADS-D in the observation group and the score of HADS-A in the control group were all reduced after treatment (P<0.01, P<0.05). The scores of abdominal pain degree in the two groups and score of diarrhea frequency in the observation group were all reduced after treatment (P<0.001). After treatment, the reducing ranges of the score of HADS-A and the scores of abdominal pain degree and diarrhea frequency in the observation group were all larger than the control group (P<0.01, P<0.05). Compared with before treatment, the plasma IDO1 concentration in the two groups and the ratios of plasma Kyn/Trp and QuinA/Kyn in the observation group were all reduced after treatment (P<0.001, P<0.05, P<0.01), the ratios of plasma KynA/Kyn and KynA/QuinA were increased after treatment in the observation group (P<0.05, P<0.01). After treatment, the changes in IDO1 concentration and the ratios of plasma QuinA/Kyn and KynA/QuinA in the observation were larger than the control group (P≤0.01, P<0.05). In the observation group, the difference in the ratio of plasma KynA/Kyn before and after treatment was negatively related to the improvement value of HADS-D (r =-0.67, P<0.05). After treatment, plasma IDO1 concentration was positively related to HADS-A in the observation group (r =0.65, P<0.05). CONCLUSION:Acupuncture and moxibustion relieve the negative emotions of anxiety and depression in CD patients at mild and moderate active stage, which is probably related to the regulation of plasma Trp-Kyn metabolic pathway.
