Brief Summary

Affective disorders (mainly including major depressive disorder and bipolar disorder) are common, chronic and highly disabling mental disorders, which lack of objective biological markers. It is believed that genetic and environmental factors are involved in the development of affective disorders. Gut microbes can affect the function of brain neural circuits by mediating metabolic, immune, endocrine and autonomic changes along the brain-gut axis. The brain can also regulate intestinal microbes through endocrine, neural structure, neurogenic exosomes and other pathways. Based on the brain-gut axis, this study intends to establish a large cohort of affective disorders, and screen out efficient and convenient biomarkers for clinical diagnosis and efficacy prediction by studying key indicators such as intestinal microbes, serum metabolites and immune indexes, brain-derived exosomes, and brain functional imaging.

Outcome Measures

Primary Outcomes (1)

  • Montgomery-Asberg Depression Rating Scale(MADRS)

    MADRS score is to evaluate the degree of depression, and the higher score means severer depression.

    0 ~16 weeks

Study Arms (3)

bipolar disorder

EXPERIMENTAL

Patients with BD depressive episode received standard treatment with quetiapine fumarate tablets, starting from 50mg/ night, titrated to a therapeutic dose of 300-400mg/ night within 10 days, and maintained treatment for 4 weeks. According to the patient's condition, patients with BD depressive episode could receive another standard treatment with lurasidone, starting from 20mg/ night, titrated to a therapeutic dose of 40mg/ night within 6 days, and maintained treatment for 4 weeks. Adverse reactions and changes in condition of all patients were recorded

Drug: Quetiapine Fumarate TabletsDrug: Lurasidone

major depressive disorder

EXPERIMENTAL

MDD depressive episode patients received standard treatment with escitalopram oxalate tablets, starting from 5mg/ day once, titrated to a therapeutic dose of 10-20mg/ day within 1 week, and maintained treatment for 4 weeks

Drug: Escitalopram Oxalate Tablets
