Depression is a common emotional disorder that seriously affects people's life and health all over the world. The pathogenesis of depression is complex, and traditional Chinese medicine (TCM) for antidepressants has a good therapeutic effect because of its multi-component, multi-pathway, and multi-target action mode. At present, the anti-depressive mechanism of TCM has not been fully clarified, but it is clear that depression is closely related to metabolic health. Therefore, in order to further explore the anti-depressive mechanism of TCM, this paper proposes research strategies on the anti-depressive mechanism of TCM based on functional metabolomics from the perspective of metabolism, the potential biomarkers of depression are analyzed with the help of multi-omics combined analysis technology, and the functional molecules of TCM for antidepressant are studied. Molecular biology techniques are used to accurately capture the molecular interactions between biomarkers of depression and functional compounds, which identify effective drug targets and further elucidate the biochemical functions and related mechanisms involved in depression metabolic disorders. This paper systematically reviews the research strategies and applications of functional metabolomics in the anti-depressive mechanisms of TCM, expounds on the core value of functional metabolomics, and summarizes the current research status and hot issues of TCM for antidepressants in recent years, providing new methods and new ideas for the study of mechanisms of TCM with the help of functional metabolomics.

Objective To analyse the spectral patterns of complementarity determining region 3 (CDR3) length distribution of T lymphocyte receptor beta chain variable (TRBV) gene families in infiltrating T cells of the liver tissues and the peripheral blood samples of patients with chronic hepatitis B (CHB) in order to evaluate the characteristics of T cell clonal expansion. Methods The spectral patterns drift of TRBV gene families (the monoclonal/oligoclonal TCR β T cells) in the peripheral blood and hepatic tissues from 11 cases of CHB patients were analyzed by the real-time fluorescence quantitative reverse transcription polymerase chain reaction (FQ-PCR) with DNA melting curve analysis, and abnormal rates of TRBV gene families were compared between CHB patients and healthy control. The comparison of rates was done by chi square test. Results The gene melting spectral pattern of 26 TRBV families of the 11 CHB patients, no matter in the peripheral blood or hepatic tissue, showed either a single peak or prominent melting peaks, even disappeared for certain TRBV families. The abnormal rate of TRBV gene families in the hepatic tissues was significantly higher than that in the peripheral blood samples (x2 = 23. 246, P<0. 01). What is more interesting was that some parts of TRBV families were identical in both the peripheral blood and the hepatic tissue in certain patients. TCR BV13.1, TCR BV17 and TCR BV22 fragments were found to be restricted used in both the peripheral blood and hepatic tissue by some CHB patients. Conclusions T cells in the peripheral blood and the hepatic tissues of CHB patients can develop clonal expansion to some extent.Parts of TRBV families are restricted used in the peripheral blood and hepatic tissue in some CHB patients, which offers a foundation for further studying the common specific spectral drift patterns of TRBV CDR3 gene in CHB patients.

The purpose of the study was to observe the effect of rapamycin (RAPA) on the differentiation and maturation of rat bone marrow-derived dendritic cells (BMDCs) in vitro. BMDCs from Wistar rats were cultured with granulocyte-macrophage colony-stimulating factor plus interleukin-4 in the presence or absence of RAPA (20 ng/mL), and stimulated with lipopolysaccharide (LPS) for 24 h before cells and supernatants were collected. Surface phenotype of BMDCs was flow-cytometrically detected to determine the expression of maturation markers, MHC class II and CD86. Supernatants were analyzed for the production of IL-12 and IFN-gamma cytokines by using ELISA. BMDCs were co-cultured with T cells from Lewis rats and mixed lymphocyte reaction was assessed by MTT method. The morphology of BMDCs stimulated with LPS remained immature after RAPA pretreatment. RAPA significantly decreased the CD86 expression, impaired the IL-12 and IFN-gamma production of BMDCs stimulated with LPS, and inhibited the proliferation of allogeneic T cells. In conclusion, RAPA can inhibit the maturation of BMDCs stimulated with LPS in terms of the morphology, surface phenotype, cytokine production, and ability of BMDCs to stimulate the proliferation of allogeneic T cells in vitro.
