Summary

Acupoints are the stimulus points and reactive points for acupuncture to treat diseases. Therefore, this study is designed to detect the pain threshold and temperature of biological specificities of acupoints in healthy control (HC) participants and major depressive disorder (MDD) participants by using pressure pain threshold gauge (PTG) and infrared thermography (IRT). Based on the results of the PTG and IRT tests, the potentially superior acupoints for the treatment of MDD will be selected separately. Then, different acupoint groups selected based on different biological specificities tests will be used for clinical treatment to evaluate the clinical efficacy of intradermal acupuncture (IA) for MDD based on changes in the biological specificities of acupoints.

Detailed description

Part 1: This study will include 50 patients with MDD (MDD group) and 50 HC participants (HC group). PTG and IRT, respectively, will be adopted to assess 2 kinds of biological specificity of MDD-related acupoints: pain sensitivity specificity and thermal specificity. Based on the results of the PTG and IRT tests, the potentially superior acupoints for the treatment of MDD will be selected separately. After statistical analysis of the data from PTG and IRT tests, 4 pressure pain threshold strong response acupoints (PSA) and 4 temperature strong response acupoints (TSA) will be selected, respectively. This part of the trial began on January 10, 2022, and its registration number is NCT06114342. Part 2: A total of 160 participants with MDD who meet the inclusion criteria will be included in the study. Patients with MDD who met the criteria will be randomly divided 1:1:1:1 into 4 groups: wait-listed treatment (WL) group, clinical common acupoint (CCA) group, TSA group, and PSA group. All participants received basic therapeutic medication for the use of one or more antidepressants. Dosing and dosage will be adjusted by a specialist. The Patient Health Questionnaire-9 (PHQ-9) and the MOS item short form health survey (SF-36) will be used as clinical efficacy outcome indicators, and each group's incidence of adverse effects will be observed. This study will investigate the effectiveness and safety of IA based on changes in the biological specificity of acupoints for MDD.

Conditions

• Major Depressive Disorder

Interventions

Type	Name	Description
DRUG	Basic treatment	1. Health education: Properly explain the causes and precautions of the patient and instruct the patient to rest regularly. In addition, care should be enhanced to avoid accidents. 2. The basic therapeutic drug is the use of one or more antidepressants, such as oral 5-hydroxytryptamine reuptake inhibitors, dual inhibitors of pentraxin and norepinephrine reuptake, noradrenergic and specific pentraxinergic antidepressants, pentraxin receptor balance antagonists, tricyclic antidepressants, etc. If there is significant sleep disturbance, benzodiazepines may be added temporarily. Dosing and dosage will be adjusted by a specialist.
PROCEDURE	PSA	Four PSA 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.
PROCEDURE	TSA	Four TSA 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.
PROCEDURE	CCA	Acupoints: LR3 (Taichong), PC6 (Neiguan), SP6 (Sanyinjiao), and HT7 (Shengmen). PC6 and HT7 will use φ0.20\*1.2mm acupuncture needle. LR3 and SP6 will use φ0.20\*1.5m acupuncture needles. 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.
