Abstract:
Objective By using resting-state fMRI (r-fMRI), to observe the effect of electroacupuncture at Quchi (LI 11) and Shangjuxu (ST 37) in changing brain activity pattern in functional bowel disorders (FBD), and to provide imaging evidence for seeking the central mechanism of Quchi (LI 11) and Shangjuxu (ST 37) in treating FBD.Method Twenty patients with functional constipation were taken as the constipation group, and 20 patients with functional diarrhea were taken as the diarrhea group. The constipation group was intervened by electroacupuncture at Shangjuxu (ST 37), while the diarrhea group was intervened by electroacupuncture at Quchi (LI 11). On the next day, the two groups both received electroacupuncture at the corresponding non-meridian point. The r-fMRI data of the two groups were collected before and after the interventions. With the functional connectivity taken as the observation index and right insular lobe as the seed point, MTLAB, DPARSF and REST were adopted to obtain the brain images functionally connected with the seed point, to further analyze the difference in brain functional connectivity before and after electroacupuncture.Result After electroacupuncture at Shangjuxu (ST 37), functional constipation patients presented positive activation in left cerebellar declive, left lingual gyrus, left middle occipital gyrus, right occipital lobe, right supramarginal gyrus, right gyrus cingula and left precuneus; the right subgyrus, right insular lobe and left insular lobe were negatively evoked. After electroacupuncture at Quchi (LI 11), patients with functional diarrhea showed significant differences in left cerebellar culmen and left posterior cingulate.Conclusion Electroacupuncture at Quchi (LI 11) and Shangjuxu (ST 37) can induce changes in brain functional connectivity related to visceral hypersensitivity in FBD patients, which is possibly associated with the effect of acupuncture in improving FBD.
