Specific electrode sites are customized for the subject through magnetic resonance scanning, the deep nucleus cluster to be stimulated-nucleus accumbens is calibrated through electric field simulation before treatment, and the stimulation target can be accurately positioned by stimulating the specific electrode sites of the subject during treatment. During the treatment period, all subjects were treated with a fixed time interference stimulation (TI) device at a frequency of 30 minutes twice a day, 5 days a week, for a total of 10 treatments. The output current intensity during treatment is 3.64 mA+4.36 mA.

Hamilton Depression Scale（HAMD-17)
The Hamilton Depression Scale（HAMD-17) was used to assess the extent of the patient's depressive episodes, with higher scores representing more severe depression, and this scale was used to monitor the patient's improvement in depression before and after treatment.
Time frame: 0-5 days
Montgomery-Asberg Depression Rating Scale（MADRS）
The Montgomery-Asberg Depression Rating Scale (MADRS) is used to reflect the effectiveness of antidepressant treatment and to monitor changes in a patient's condition. The scale is a stand-alone scale whose ratings are based on a clinical interview with questioning about symptoms that leads to a rating of depression severity.
Time frame: 0-5 days
Hamilton Anxiety Scale（HAMA）
The Hamilton Anxiety Scale is primarily used for the assessment of anxiety levels, and has 14 items, each of which has a 0-4 scale, with anxiety possible above a score of 7. The higher the score, the more severe the anxiety.
Time frame: 0-5 days
Young Mania Rating Scale（YMRS）
The Young Mania Rating Scale is mainly used to assess the manic symptoms of the subjects before and after the treatment, there are 11 items, each symptom has a working scale, divided into 5 levels, the level score of each item is different, most of them are 0-4, in which the 5th, 6th, 8th and 9th items are scored as 0, 2, 4, 6, 8, and the higher the total score of the subject the more serious the degree of mania.
Time frame: 0-5 days
Snaith-Hamilton Pleasure Scale（SHAPS）
The Snaith-Hamilton Pleasure Scale is a self-report scale that assesses the degree of the subject's pleasure deficit; the higher the score, the more severe their pleasure deficit. The scale was used to assess the degree of improvement in the patients' pleasure deficit before and after treatment.

Temporal Experience of Pleasure Scale (TEPS)
The Temporal Experience of Pleasure Scale (TEPS) is a self-report scale that assesses an individual's anticipation and experience of future pleasure, with higher scores suggesting a stronger experience of pleasure. The scale was used to evaluate the degree of improvement of pleasure deficit before and after treatment.
Time frame: 0-5 days
