In this study,the investigators will test the antidepressant effect of acupuncture versus sham intervention on major depression, in an eight-week, double-blind, randomized-controlled trial in 40 MDD patients who still have significant depressive symptoms without changing at their treatment modality for the last 4 weeks. During the visits at weeks 0 (baseline), 1, 2, 4, 6, 8 (intervention), and 12 (4 weeks after intervention), subjects will be assessed depressive symptoms with the 21-item Hamilton Rating Scale for Depression (HAM-D). Before and after the intervention (Weeks 0 and 8),Computerized TCM constitution diagnosis will be measured and the blood samples will be collected for biomarker analyses, including neurotransmitter, inflammatory molecules and immunologic function. All parts of this research will start after being approved by the Institution Review Board in study sites.
The outcomes of this study could provide the evidence of applying acupuncture as an alternative effective treatment for depression and to improve the understanding of biological mechanisms for its antidepressant effects.
