ABSTRACT

Objective: To observe the therapeutic effect of mild moxibustion on irritable bowel syndrome (IBS) visceral hyperalgesiamodel rats and its regulatory effect on P2X3 receptors in the spinal cord, anterior cingutate cortex (ACC) and thalamic ventral posterolateral nucleus (VPL). Methods: Thirty 8-day-old newborn rats were randomly divided into a normal group (n=6) and a modeling group (n=24) according to the completely random number table method. Rats in the normal group were bred routinely, and those in the modeling group were subjected to preparing IBS chronic visceral hyperalgesia model using colorectal distention (CRD) in stimulation method. Rats successfully modelled were re-divided into a model group, a mild moxibustion group, a P2X3 receptor antagonist group, and a normal saline group according to the completely random number table method with 6 rats in each group. Rats in each group received corresponding interventions from the 37-day old, once a day for 7 consecutive days. Immunohistochemistry and Western blot assays were used to detect P2X3 protein expressions in the spinal cord, ACC and VPL of rats. Results: Under different intensities of CRD stimulation, the abdominal withdrawal reflex (AWR) scores of the model group were significantly increased versus the normal group (all P<0.05); the AWR scores of the mild moxibustion group and the P2X3 receptor antagonist group were significantly reduced versus the model group (all P<0.01). The P2X3 protein expressions in rat spinal cord, ACC and VPL tissues of the model group were significantly increased versus the normal group (all P<0.01); the P2X3 protein expressions in rat spinal cord, ACC and VPL tissues of the mild moxibustion group and the P2X3 receptor antagonist group were significantly reduced versus the model group (all P<0.01). Conclusion: Mild moxibustion can inhibit the P2X3 receptor expressions in the spinal cord, ACC, and VPL tissues of IBS visceral hyperalgesia model rats, which may be the mechanism of mild moxibustion in relieving the central sensitization of rats with IBS visceral hyperalgesia.

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 (@*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.
