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.

AIM: To evaluate the effects of the extract of Buddleja officinalis eye drops in basic tears secretory volume, tear film stability, expression of androgen receptors(AR) in castrated rats with dry eye, and to investigate the therapeutic effects of extract of Buddleja officinalis on dry eye caused by gonadal hormones level imbalance. METHODS:A total of 45 Wistar masculinity rats were divided at random into 9 groups, including normal group(A1,A2 and A3), model group(B1,B2 and B3), therapy group with extract of Buddleja officinalis eye drops(C1,C2 and C3). The "1" stood for being fed for 1 month, and "2" for 2 months, and "3" for 3 months. The dry eye model was established with orchiectomy on group B,C. Group C was treated with Buddleja officinalis extract eye drops for one month. All rats were checked with Schirmer Ⅰ test (SⅠt) and tear film break-up time (BUT). Expression of AR was analyzed by flow cytometer(FCM). RESULTS:The SⅠt value of group C was significantly higher than that of group B (P<0.01) and the BUT value of group C was significantly longer than that of group B (P<0.01), which indicated the eye drop could significantly keep basic tears secretory volume and tear film stability. And the expression of AR of group C was much higher than that of group B,which showed that available composition of the eye drops maybe display androgen-like activity.CONCLUSION:The main components of extract of Buddleja officinalis is the flavonoids which could significantly inhibit happening of dry eye of rat after androgen level lowered. Its mechanism is like androgen's and it could display androgen-like activity to keep basic tears secretory volume and tear film stability.

AIM: To explore the effect of Buddleia flavonoids drug-containing plasma and androgen receptor(AR) blocker on the expression of STAT1 phosphoprotein.METHODS: In vitro lacrimal gland epithelial cells were cultivated with H2O2 to establish the dry eye apoptosis state. Blank plasma group, Buddleia officinalis plasma total flavonoids interfere with drug-containing group, and the intervention group of testosterone propionate were set. The expressions of STAT1 phosphoprotein of each group were observed by Western blot and AR blocker flutamide was used to explore the intended androgen effect of Buddleia flavonoids.RESULTS: After the intervention of drug-containing plasma, the expression of STAT1 Phosphoprotein in Buddleja officinalis drug-containing plasma intervention group(0.353±0.494) and testosterone propionate intervention group(0.502±0.036) were enhanced and the differences between the two groups were significant (P<0.01). After using the AR blocker in all groups, the expression of STAT1 phosphoprotein in each group (0.268±0.061,0.283±0.106,0.213±0.071) had no difference.CONCLUSION: Buddleja officinalis drug-containing plasma total flavonoids can promote the expression of STAT1 phosphorylation.

AIM: To evaluate the effects of total flavonoid of chrysanthemum on the expressions of Fas and FasL in male rabbits with dry eye, and to investigate the therapeutic effects of the total flavonoid of chrysanthemum on dry eye.
METHODS: Totally 150 male Japanses white rabbits were divided into blank group ( group A ) , sham -operated group ( group B ) , model group ( group C ) , androgen control treatment group (group D), and total flavonoid of chrysanthemum treatment group ( group E ) . The dry eye model was established with orchiectomy on group C, D and E. Rabbits in group E were treated with total flavonoid of chrysanthemum. Rabbits in group D were treated with androgen intramuscular injection. Rabbits in the group A, group B, group C was treated with normal saline. All rabbits were detected with Schirmer's Ⅰ test and tear break-up time (BUT). Fas, FasL were checked on immunohistochemistry.
RESULTS:The Schirmer's I test values of group E was significantly higher than that of group C ( P<0. 01 ) and the BUT value of group E was significantly longer than that of group C ( P<0. 01 ). The quantity of positive expression of Fas in glandular tube cell and acinar epithelial celland apoptosis cells of group E after treatment at 1, 3, 5mo were significantly lower than that of group C, cell population of the positive expression of FasL was obviously higher than that of group C (P<0. 01).
CONCLUSION:The main component of chrysanthemum is flavonoid, which could significantly inhibit happening of dry eye in rabbit after androgen level lowered and lacrimal gland apoptosis and keep basic tears secretory volume and tear film stability.

Objective: To compare the clinical efficacy between 'warming-unblocking needling technique' and reinforcing method by twirling in treating knee osteoarthritis (KOA) due to deficiency of liver and kidney. Methods: A total of 72 patients with KOA were divided into a warming-unblocking group and a reinforcing group by complete randomized method, with 36 cases in each group. Xuehai (SP 10), Heding (EX-LE 2), Liangqiu (ST 34), Neixiyan (EX-LE 4), Xizhong (Extra), Dubi (ST 35), Yinlingquan (SP 9), Zusanli (ST 36) and Yanglingquan (GB 34) were the main points in both groups. Taichong (LR 3), Taixi (KI 3) and Sanyinjiao (SP 6) were the combined points. 'Warming-unblocking needling technique' was applied in the warming-unblocking group, and reinforcing method by twirling was applied in the reinforcing group. The treatments were performed once a day, 10 times as a treatment course, at a 2-day interval between two courses, for 3 courses in total. The scores of Western Ontario and McMaster Universities osteoarthritis index (WOMAC) in the two groups were observed before and after the treatment, and the clinical efficacy was compared. Results: After treatment, the total effective rate was 94.3％ in the warming-unblocking group and 87.9％ in the reinforcing group, and the difference between the two groups was statistically significant (P<0.05). The component scores of pain, stiffness and daily activities in WOMAC and total WOMAC scores in both groups decreased after treatment (all P<0.01). The component and total WOMAC scores in the warming-unblocking group were lower than those in the reinforcing group (P<0.05 or P<0.01). Conclusion:'Warming-unblocking needling technique' has significant efficacy than reinforcing method by twirling in treating KOA due to deficiency of liver and kidney. It can significantly improve pain, stiffness and daily functional activities of patients.

Objective To compare the difference of protein and lipid metabolism between patients with inflammatory bowel disease and healthy controls,and to investigate the association of these changes with disease activity and location of the lessions.Methods The retrospective cohort study was carried out.The data of protein and lipid metabolisms collected from 195 patients with ulcerative colitis,76patients with Crohn's disease and 97 healthy controls during 1995 to 2007 were analyzed.Disease activity were evaluated using simple clinieal colitis activity index and simple index of Crohn's disease activity.The erythrocyte sedimentation rate(ESR)and C-reactive protein(CRP)were measured.Results Serum levels of ESR in patients with ulcerative colitis were negatively linear correlated with serum levels of albumin/globulin ratio(β=-0.521,P＜0.01)and positively linear correlated with serum levels of α2globulin(β=0.319,P＜0.01).Serum levels of globulin in patients with Crohn's disease were positively linear correlated with serum levels of ESR(β=0.558,P＜0.01)and CRP(β=0.424,P=0.01).In ulcerative colitis,serum levels of albumin/globulin ratio,albumin and total cholesterol were significantly higher in patients with proctosigmoiditis than those in patients with lesions at other locus(P=0.003,0.005,0.038,respectively).In Crohn's disease,serum level of globulin was significantly higher in patients with lesions only at colon than that in patients with lesions only at small bowel(P=0.029).Conclusions Serum levels of albumin/globulin ratio and α2-globulin can be predictors of inflammatory activity in patients with ulcerative colitis.The increasing serum globulin may predict the progression of disease activity in patients with Crohn's disease.The nutritional deficiency is more critical in patiens with small bowel involvement than those with colon involvement.
