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 investigate the prevalence and associated factors of fecal incontinence (FI) and urinary incontinence (UI) in postpartum Chinese women.Methods Questionnaires about FI and UI symptoms were completed via telephone interviews conducted within six months after delivery.Multi-variant Logistic analysis was applied for relation between delivery mode and FI or UI.Results (1) Two thousand and twelve postpartum women were admitted into this study,among which 14 (0.7％) had FI within 6 months after delivery.Logistic regression analysis showed that FI was significantly associated with forceps delivery (OR =20.09,95 ％ CI:3.64-110.90,P =0.000),and mediolateral episiotomy (OR=6.11,95％ CI:1.29-28.80,P=0.024).(2) Among the 2012 women,the prevalence of UI,stress urinary incontinence (SUI),urgent urinary incontinence (UUI)and mixed urinary incontinence (MUD was 10.04％ (n=202),8.15％ (n=164),0.94％ (n=19)and 0.94 ％ (n =19),respectively.Logistic regression analysis found that SUI prevalence was related to maternal age (OR =1.07,95％ CI:1.04-1.11,P =0.000),maternal weight before delivery (OR=1.04,95％ CI:1.02-1.06,P=0.001),neonatal head circumference (OR=1.20,95％ CI:1.05-1.39,P =0.010),mediolateral episiotomy (OR =4.96,95 ％ CI:3.05-8.07,P =0.0005 ),spontaneous vaginal delivery (OR=5.22,95％ CI:2.53-10.76,P=0.000) and forceps delivery (OR=9.20,95％ CI:4.07-20.79,P=0.000).UUI was related to maternal weight before delivery (OR=1.51,95％ CI:1.12-2.05,P=0.008).MUI was related to maternal weight before delivery (OR=1.06,95％ CI:1.00-1.11,P=0.049),duration of second stage of labor (OR=1.01,95％ CI:1.00-1.03,P =0.010),mediolateral episiotomy (OR =7.76,95％ CI:1.42-42.52,P=0.017) and forceps delivery (OR=15.21,95％ CI:1.61-143.44,P=0.018).(3) The prevalence of SUI was higher at 4 days and 42 days after delivery (7.95％ and 9.10％).Conclusions (1) F1 and UI prevalence is lower in this study than in other reports.(2) Vaginal delivery is a risk factor for women's FI and UI,especially forceps delivery and mediolateral episiotomy.(3) Maternal age,pre-delivery weight,newborn head circumference,spontaneous vaginal delivery,forceps delivery and mediolateral episiotomy might increase the risk of UI.

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.

In order to obtain higher L-lactic acid yield industrial strain, the original strain Rhizopus oryzae PW352 was mutated by means of N+ ions implantation and a mutant strain Rhizopus oryzae RE3303 was obtained. Its lactic acid yield was increased by 75% than that of the original one. The acid producing condition was optimized by orthogonal design. The concentration of L-lactic acid reached to 131～136g/L and the conversion rate of glucose was as high as 86%～90% under the optimum condition.

Objective To investigate the effect of glucose supplement on AMPK activation in myocardium of exercised rats by measuring the myocardial AMPK activation and glycogen content after acute exercise training.Methods Rats were subjected to an acute endurance exercise and glucose supplement in varying doses and time points before and after exercise.The dynamic changes of myocardial AMPK activities was measured with Western blotting, changes of myocardial glycogen content were measured with Anthrone method.Results AMPK activation in myocardium of exercised rat was increased significantly throughout the exercise, and remained at a higher level 1 hour after acute exercise.However the level of AMPK activity was not significantly increased in exercised rat with glucose supplement.Glycogen content was not significantly changed after exercise.Rats subjected to lower dose glucose supplement did not show significant changes in glycogen content neither.But glycogen content was significantly increased in rats at 24 hours after exercise, subjected to higher dose of glucose supplement.Conclusions 1) Acute exercise induces a significant increase in AMPK activation in myocardium of exercised rats.Glucose supplement significantly inhibites the activation of AMPK induced by acute exercise.(2) Higher dose glucose supplement significantly increases glycogen content in the rat myocardium 24 h after exercise.

Objective To explore the energy feature of the spontaneous neural activity in depressive patients with diurnal rhythm.Methods Twenty depressive patients with diurnal rhythm,20 depressive patients without diurnal rhythm and 20 gender-,age-,education-matched healthy controls were scanned with 3.0 T MRI Scanner.According to Results of ANOVA,group-wise two sample t-test was completed.The correlation analysis were conducted between ALFF of significant difference brain regions and the score of Hamilton rating scale for depression.Results The brain regions showing significant differences among three groups were located in the right parahippocampal gyrus(MNI:18,-36,-9;K=136),left parietal lobe(MNI:-54,-45,42;K=86),left cerebellum crus(MNI:-84,-60,36;K=86) and right cerebellum crus(MNI:9,-78,-36;K=91)(P<0.05,Alphasim correct).Compared with non-diurnal rhythm group,the diurnal rhythm group showed significantly increased ALFF in the right parahippocampal gyrus.Compared with healthy group,the diurnal rhythm group showed significantly increased ALFF in right parahippocampal gyrus,left parietal lobe,and significantly decreased ALFF in left cerebellum crus 1 and right cerebellum crus 2.Compared with healthy group,the non-diurnal rhythm group showed significantly increased ALFF in left parietal lobe,and significantly decreased ALFF in left cerebellum crus 1 and bilateral cerebellum crus 2.No correlation between ALFF of significant difference brain regions and clinical symptoms was found(P>0.05).Conclusion The diurnal rhythm observed in depression may be associated with aberrant activity of parahippocampal gyrus.

Objective To investigate the changes of cortical thickness and surface area in patients with bipolar depression(BD),and to explore the relationship between abnormal changes in gray matter and clinical symptoms.Methods 28 BD patients and 28 healthy controls underwent T1-weighted MRI.The Freesurfer software was used to process the T1 images,which used a set of automated sequences to analyze cortical thickness and surface area on 66 regions (33 regions of each hemisphere),and the correlation with clinical features was also calculated.Results Compared with controls,BD patients showed thinner cortical thickness in left medial orbitofrontal cortex((2.40±0.12) mm vs (2.55 ±0.18) mm,P=1.2× 10-3) and left rostral anterior cingulate((2.66±0.21) mm vs (2.88±0.27) mm,P=3.1 × 10-4),and smaller area of left cuneus((1 443.13± 131.00) mm2vs (6 634.70±600.16) mm2,P=2.7× 10-4) and right superior frontal gyrus ((6 634.70±600.16) mm2vs (7 300.50±653.39) mm2,P=1.3× 10-3).In addition,the negatively correlation was found between the cortical area of left cuneus and effective illness duration (r=-0.471,P=0.018),and the cortical thickness in left rostral anterior cingulate and total score of HAMD-17(17-item Hamilton Rating Scale for Depression) (r=-0.508,P=0.009).Conclusion There are abnormal altertion of cortical thickness and cortical areas of emotional circuit in bipolar depression,but the brain areas are not completely overlapping.Correlation analysis suggests that cortical thickness and area is related to different clinical features.

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.
