Acupuncture Therapy Based on Biological Specificity of Acupoints for Major Depressive Disorder

In this study, SSRIs antidepressants will be used, and the oral dose will be determined by the clinical specialist. Once-daily for 6 weeks.

This study will use the intradermal needle as an acupuncture intervention. Strong reaction acupoints selected in the first part of the study will be stimulated. According to the position of the acupoints, choose a needle of φ0.20\*1.5m or φ0.20\*1.2mm. Press the needle to insert the acupoint vertically and retain it in the skin. After the intervention, the needle will be retained for 72 hours with a day of rest after removal. During needle retention, participants will be instructed to press the acupoints 3-4 times a day for about 1 minute each time, with the amount of stimulation as much as the patient can tolerate, at an interval of about 4 hours. A total of 10 treatment sessions will be performed for 6 weeks.
