Aim To investigate the effect of resveratrol (Res)on septic mice and LPS-insulted H9c2 cells,as well as its involved mechanisms.Methods By use of a mouse cecal ligation and puncture-induced septic model (CLP),the survival of septic mice was evalua-ted after resveratrol treatments.H9c2 cells were insul-ted by LPS and then treated with resveratrol,the mR-NA expressions of TNF-α,SIRT1 and other class III HDAC members were detected using RT-PCR and real-time PCR,Finally,the protein levels of nuclear p65, an important subunit of NF-κB,were measured in H9c2 cells using Western blot assay,to reveal the effect of resveratrol on LPS-induced nuclear transloca-tion of NF-κB.Results Compared with the control septic animals,intraperitoneal injection of resveratrol (1 or 5 mg·kg -1 ·d -1 )significantly increased the survival of septic mice.Furthermore,resveratrol signif-icantly increased mRNA expressions of SIRT1,SIRT2, SIRT6 and SIRT7 in LPS-insulted H9c2 cells.Res-veratrol also remarkably inhibited LPS-induced nuclear translocation of NF-κB.Conclusion An appropriate dose of resveratrol protects septic mouse hearts from the injury induced by LPS through the activation of SIRT family members and the inhibition of NF-κB pathway.

Objective To explore the prognostic factors of non-small-cell lung cancer (NSCLC) patients with brain metastasis. Methods 122 NSCLC patients with brain metastasis from Jan 2007 to Dec 2012 were incorporated, and followed with death as the end. The influence factors of prognosis were retrospective analyzed. Kaplan-Meier method was used for survival analysis, the Log-rank test for single factor analysis,and Cox regression model for multiple factors analysis. Results The single-factor and multi-factor analysis showed that the influence factors of prognosis were age, pathological type, number of intracranial metastasis, presence of extracranial metastasis, treatment, Karnofsky score, the original site control situation (P<0.05). Gender, the size of the original site had no influence for prognosis (P>0.05). The average survival times of patients with palliative symptomatic treatment, simple whole brain radiotherapy, whole brain radiotherapy local lesion plus the amount of radiation, whole brain radiotherapy local lesion plus the amount of radiation combined with chemotherapy were (2.14 ±0.19) months, (7.28 ±0.60) months, (16.90 ±1.35) months, (17.7±1.12) months, 1 year survival rates were 0, 8.5%, 71.0%, 93.3%. Survival analysis showed that there was statistical significance among the four groups (P= 0.000). Conclusion The age, pathological type, number of intracranial metastasis, presence of extracranial metastasis, treatment, Karnofsky score, the original site control situation are the prognosis factors in NSCLC patients with brain metastasis, therefore the treatment of these patients should be comprehensively analyzed.

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.

OBJECTIVETo evaluate incidence of postoperative delirium after hip surgery in elderly patients by meta-analysis.
METHODSFrom January 1, 2014 to December 31, 2013, clinical literatures about postoperative delirium after hip surgery in elderly patients,were searched from the Pubmed. Literature extract table were formed according to inclusion and exclusion criteria. Stata-12.0 was applied for Meta-analysis. P was used to test heterogeneity of study, random-effect model was performed when I2 > 50%. Subgroup analysis was used according to stage of age, assessment scale of delirium and statistical area of literature. Begg test was used to test publication bias.
RESULTSTwenty-one literatures were included. Incidence of postoperative delirium after hip surgery in elderly patients by weighted and combination was 17% [95% CI (16%, 18%)]. Incidence of postoperative delirium after optional hip surgery was decreased more than emergency operation in included 5 literatures [OR = 0.32, 95% CI (0.22, 0.45)]. Incidence of postoperative delirium in patients less than 80 years old was 21% [95% CI (19%, 23%)], while 21% [95% CI (19%, 24%)] in patients more than 80 years old. Incidence of postoperative delirium in CAM evaluation scale was 23% [95% CI (21%, 26%)], while 19% [95% CI (17%, 21%)] in other evaluation scales. Incidence of postoperative delirium in Asian area was 17% [95% CI (15%, 20%)], while 23% [95% CI (21%, 25%)] in European and American area. There was no publication bias tested by Begg test (P < 0.05).
CONCLUSIONIncidence of postoperative delirium after hip surgery in elderly patients increases higher, especially in emergency operation. A standardizing research method is benefit for evaluate incidence of postoperative delirium after hip surgery in elderly patients, decreasing heterogeneity and publication bias.

Objective To build experimental animal model of cerebral alveolar echinococcosis disease of sheep,in order to study of human alveolar hydatid disease of the brain.Methods Experiment animal models of ten Xinjiang big-tail sheep were performed by, direct skull puncture,intracerebral inoculation of echinococcus multilocularis.MRI was used to observe the growth status of cerebral alveolar echinococcosis disease of sheep after 8 months,and morphological and pathological characteristics after autopsy were ana-lysed.Results 4 sheep models (40%)were successful built which were confirmed by pathology and MRI.On MRI,4 cases all were single lesion,on T2 WI there was multiple follicles bubbles under the background of low signal in one case,and low signal in other three cases.Under the microscope,a large number of lymphocytes,eosinophils and plasma cells infiltrated the lesion area,around which small blood vessels were blocked and had inflammatory reaction were showed.Conclusion The method using artificial inocula-tion rat alveolar echinococcosis to establish experimental model of cerebral alveolar echinococcosis disease of sheep has the character-istic of feasibility,simplicity and repeatability.

Objective The predictive value of the metabolic syndrome (MetS) for mortality from all-cause and cardiovascular disease (CVD) in the Chinese population is unclear. The aim of this present study was to compare MetS with its individual components as predictors of mortality in Chinese elderly adults. Methods A cohort of 1,535 subjects (994 men and 541 women) aged 50 years or older was selected from employees of a machinery factory in 1994 and followed until 2009. Cox models were used to estimate the hazard ratios (HRs) predicted by MetS according to the harmonized definition and by its individual components. Results The baseline prevalence of MetS was 28.0% in men and 48.4% in women. During a median follow-up of 15 years, 414 deaths occurred, of these, 153 participants died from CVD. Adjusted for age and gender, the HRs of mortality from all-cause and CVD in participants with MetS were 1.47 (95% confidence interval (CI): components. On evaluating the MetS components individually, we found that, independent of MetS, only hypertension and impaired glucose predicted higher mortality. Conclusions The number of positive MetS components seems no more informative than classifying (dichotomous) MetS for CVD risks assessment in this Chinese cohort.
