This study aims at investigating the special effectiveness of antidepressant effect of Fluvoxamine for endogenous depression. The investigators also aim to assess the effect of Fluvoxamine on the multimodal magnetic resonance imaging(MRI), blood cytokines, feces bacteria flora and neuropsychological performance in depression patients with melancholic features. The investigators further aim to identify the predictors of Fluvoxamine's antidepressant effeect using the above techniques.

RECRUITINGChange in Hamilton Depression Rating Scale-17 item (HAMD-17)
Interview-based questionnaire used to measure the severity of depression. Consists of 17 items with a score calculated. Higher scores are associated with more severe depression.
Time frame: Baseline, 2weeks, 1 months, 2 months
Change in Hamilton Anxiety Rating Scale-14 item (HAMA-14)
Interview-based questionnaire used to measure the severity of anxiety. Consists of 14 items with a score calculated. Higher scores are associated with more severe anxiety.
Time frame: Baseline, 1 months, 2 months
Change in voxel-based morphometry of grey matter, white matter as assessed by structural magnetic resonancce imaging
Participants will receive resting-state functional magnetic resonance imaging (MRI). Scans will be performed on a 3.0- T Siemens Magnetom Skyra scanner (Siemens Healthineers, Erlangen, Germany). During scanning, all participants were instructed to remain motionless, and to think of nothing in particular but to not fall asleep.
Time frame: Baseline, 2 months
Change in Functional connectivity
Change in Functional connectivity of the brain networks as assessed by measure of connectivity in multimodal MRI.
Time frame: Baseline, 2 months
Change in peripheral blood cytokines
Peripheral blood sample will be collected and the concentration of IL-6, TNF-α, and CRP will be assessed.
Time frame: Baseline, 1 months, 2 months
Change in feces bacterial flora
The objective of investigator is to characterize gut microbiome in patients with TRD. To explore the specific diversity of gut microbiome. The stool samples were collected in the collection kits at the baseline, and were frozen at -80 °C. After the process of DNA Purification, 16S rRNA Gene Amplification and Illumina MiSeq sequencing, the study finally find the abundance and diversity of microbiota.

Change in Congruent STROOP Time to Complete (Executive Function)
Stroop Colour Naming Test (STROOP) is a cognitive test designed to assess the ability to inhibit a prepotent response to reading words while performing a task that requires attention control. It comprises two sheets with 50 words on each, and each word is the name of a colour. On the first sheet, the Congruent STROOP Sheet, the word and ink colour match; on the Incongruent STROOP Sheet, the word and ink colour do not match. For each sheet, the patient has 4 minutes to name the ink colour of each word. When the patient finishes the sheet, or once 4 minutes is up, the clinician notes the time taken and counts the number of correct and incorrect responses. The scale ranges from 0-100, the higher score the greater the cognitive flexibility.
Time frame: Baseline, 1 months, 2 months
Change in DSST (Number of Correct Symbols)
Digit Symbol Substitution Test (DSST) is a cognitive test designed to assess psychomotor speed of performance requiring visual perception, spatial decision-making, and motor skills. It consists of 133 digits and requires the patient to substitute each digit with a simple symbol in a 90-second period. Each correct symbol is counted, and the total score ranges from 0 (less than normal functioning) to 133 (greater than normal functioning)." as a description of DSST.
Time frame: Baseline, 1 months, 2 months
Improvement on Snaith-Hamilton Pleasure Scale (SHAPS)
The Snaith-Hamilton Pleasure Scale (SHAPS) assesses the anhedonia symptoms of MDD patients, with higher score indicating more severe anhedonia. Evaluating the patient's pleasure experience and choosing the degree of agreement with the happy response in some pleasant situations, and each item was rated on a 4-point scale."1 = Strongly agree, 2 = agree, 3 = disagree and 4 = strongly disagree" This scale evaluates the status of patients in the recent period of time, The total score of the scale is the sum of the scores of 14 items, with a total score of 14-56. The higher the total score, the more serious the anhedonia.
Time frame: Baseline, 1 months, 2 months
