What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The change in MADRS total score from baseline
Time Frame: 8 weeks
There are a total of 10 projects in Montgomery-Asberg Depression Rating Scale(MADRS), each with a 7-point scoring system ranging from 0 to 6 points. The higher the score, the more severe the degree of depression.
8 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The change in HAMD-17 total score from baseline
Time Frame: 8 weeks
There are a total of 17 projects in Hamilton Depression Scale-17(HAMD-17). Scores are distributed on a scale of 0 to 53. A score above 24 indicates severe depression, a score of 17 indicates moderate depression, and a score below 7 indicates no depressive symptoms.
8 weeks
The effective rate of HAMD-17
Time Frame: 8 weeks
The effective definition of HAMD-17 is that the reduction rate of HAMD-17 score relative to baseline is ≥ 50%.

The response rate of MADRS
Time Frame: 8 weeks
The response definition of MADRS is that the score ≤ 12 points.

Perform the Clinical Global Impression Scale (CGI-S) score from Visit 1 to Visit 7,The highest score is 7 points, and the higher the score, the more severe the condition will be.
8 weeks
Proportion of participants with a CGI-S score of 1/2
Time Frame: 8 weeks
Perform the Clinical Global Impression Scale (CGI-I) score from Visit 3 to Visit 7.The highest score is 7 points, and the higher the score, the more severe the condition will be.

Proportion of CGI-I Scores on the Clinical Global Impression Scale
Time Frame: 8 weeks
Perform the Clinical Global Impression Scale (CGI-I) score from Visit 3 to Visit 7.The highest score is 7 points, and the higher the score, the more severe the condition will be.
8 weeks
The change in MADRS Single item score from baseline
Time Frame: 8 weeks
Each single item has a 7-point scoring system ranging from 0 to 6 points. The higher the score, the more severe the degree of depression.
8 weeks
The change in HAMD-17 factor score from baseline
Time Frame: 8 weeks
  1. Items scored 0-4 (5-point scale, 8 items) Depressed mood, feelings of guilt, suicide, work and interests, retardation, agitation, psychic anxiety, somatic anxiety
  2. Items scored 0-2 (3-point scale, 9 items) Difficulty falling asleep, insomnia during sleep, early awakening, gastrointestinal symptoms, general somatic symptoms, genital symptoms, hypochondriasis, weight loss, insight. The higher the score, the more severe the degree of depression.
8 weeks
The change in HAMA total score from baseline
Time Frame: 8 weeks
There are a total of 14 projects in Hamilton Scale(HAMA).The total score ranges from a minimum of 0 to a maximum of 56. The higher the score, the more severe the anxiety.
8 weeks

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
The change in ISI total score from baseline
Time Frame: 8 weeks
There are a total of 7 projects in Insomnia Severity Index(ISI) . The total score ranges from a minimum of 0 to a maximum of 28. The higher the score, the more severe the degree of insomnia.
8 weeks
The change in DSST total score from baseline
Time Frame: 8 weeks
Participants are required to match symbols with numbers according to the coding key as many as possible within 90 seconds. One point is awarded for each correct matching item; the first 10 sample items are unscored and not timed. The total score ranges from a minimum of 0 to a maximum of 90. Higher scores indicate better cognitive processing speed and represent a superior outcome. The lower the score, the worse of the cognitive function.
8 weeks
The change in PDQ-D total score from baseline
Time Frame: 8 weeks
The total score ranges from a minimum of 0 to a maximum of 80. The higher the score, the worse of the cognitive function.
