[Abstract] Objective: To observe the clinical efficacy of auricular electro-acupuncture on treatment-resistant depression (TRD), and then to explore its brain mechanism monitored by resting state functional magnetic resonance imaging (rs-fMRI).Materials and Methods: 20 patients with TRD were enrolled with the auricular electro-acupuncture for 8 weeks. Before the treatment (week 0) and after treatment (week 8), 17 Hamilton Depression Scale (HAMD-17) was used to evaluate its antidepressant effect; Using rs-fMRI technique. The rs-fMRI scans were performed on a 3.0 T MRI scanner (Magnetom Skyra, Siemens, Germany) before and after 8-week. We selected the bilateral rACC as the seed regions to compare the changes of functional connectivity (FC) before and after treatment. Finally to analyze the correlation between clinical efficacy and changes in FC after 8 weeks in TRD.Results: 17 subjects with TRD completed clinical studies. Comparing the HAMD-17 scores between 0 week and 8 weeks after treatment, the differences show statistically significant (P<0.001). 9 subjects with TRD completed brain mechanism studies. FC increased between the right rACC and the left Precuneus/ Postcentral_L(aal), the left rACC and left Lingual Gyrus/left Precuneus/Postcentral_L(aal); FC decreased between the left rACC and the right Precuneus. The FC increases between the left rACC and left lingual gyrus was significantly positively associated with the HAMD-17 score reduction (r=0.840, P=0.005).Conclusions: Auricular electro-acupuncture is effective in the treatment of TRD. Its antidepressant effects is possible related with the FC between rACC and precuneus, rACC and lingual gyrus. |
