Background

Acupuncture is an important component of traditional Chinese medicine, and is used for treating depression (MDD) from ancient times as a non-drug intervention means. In recent years, both review of acupuncture treatment MDD and Meta analysis indicate that it is a safe and effective antidepressant therapy. Neuromodulation therapy is a novel non-drug treatment strategy that has been motivated by the development of neuroscience in recent years, and Vagus Nerve Stimulation (VNS) and Trigeminal Nerve Stimulation (TNS) therapies currently belonging to their categories have been used in the study of the treatment of MDD. In China, the acupuncture and anti-depression treatment are mostly selected from the head acupuncture point and the ear acupuncture point at present. Baihui and Yintang are used as two major points for anti-depression treatment recommended by 'evidence-based acupuncture clinical practice guideline-depression', and a large number of clinical tests show that the two points can be effectively relieved from depression by electric stimulation.
