Aerobic glycolysis,which is also termed as Warburg effect,is one of the most common and profound biochemical phenotypes of tumor ceils.Several oncogenes and tumor suppressors genes have been implicated in aerobic glycolysis.MicroRNAs can control this metabolic switch by regulating oncogenes and tumor suppressors genes in a post-transcriptional way.A deeper understanding of the mechanisms and pathways by which miRNAs regulate the aerobic glycolysis will hopefully lead to a new therapeutic strategy for malignant cancer.

Objective: The purpose of this study is to investigate the mechanism for the TRAIL (TNFrelated apoptosis-inducing ligand) expression in NK (natural killer) cells stimulated by NDV (Newcastle disease virus). Methods: Pure NK cells were isolated by using MACS (magnetic activated cell sorting). The cytotoxicity of NK cells stimulated by NDV was detected by LDH releasing assay. TRAIL transcription levels in NK cells stimulated by NDV were detected through RFQ-PCR (real-time fluorogenic quantitative-PCR). TRAIL expression on NK cell membrane stimulated with NDV for 16 h was analyzed by FCM (flow cytometry). The level of IFN (interferon) -γ was determined by ELISA after NK cells were stimulated by NDV. TRAIL expression on NK cell membrane was analyzed by FCM after applying the anti-human IFN-γ while NDV was added into NK cell medium. Results: The purity of NK cells detected by FCM was (90.60± 1.15)%. NDV can enhance the cytotoxicity of NK cells after stimulation for 16 h, and the cytotoxicity of NK cells reached (22.28±0.84)% after stimulation with 204.8HU NDV. TRAIL mRNA expression levels were increased after stimulation with various concentrations of NDV for 4 h. TRAIL expression on NK cell membrane was significantly increased after stimulation with NDV for 16 h. IFN-γ level was significantly increased after NK cells were stimulated by NDV, consistent with the concentration of NDV and it was time-dependent. IFN-γ level reached a peak of 796.47±37.87 pg/mL after stimulation with 25.6 HU NDV for 16 h. TRAIL expression was significantly decreased after IFN-γ was neutralized. Conclusion: NDV can enhance the expression of IFN-γ in NK cells, and IFN-γ can up-regulate the TRAIL expression. This is one of the mechanisms for TRAIL expression on NK cells stimulated by NDV. Besides this mechanism, there exists another mechanism for TRAIL expression on NK cells directly stimulated by NDV. Copyright © 2012 by TUMOR.

Objective To investigate the prevalence of metabolic syndrome (MS) among residents in Shuimogou district of Urumqi city and to compare the differences between the Uygur and Han Populations. Methods Adopting cluster sampling, a survey of diabetes mellitus was conducted in Shuimogou district in June, 2008. Data of total 2420 subjects aged over 18 years with complete data, including background information of each individual, blood pressure, lipid profile, blood glucose and so on, were analyzed in this study. The criterion of the China Diabetes society (CDS) in 2004 was applied for diagnosis. Results The crude prevalence rates of MS were 12.85% in total, 14.91% in male and 7.39% in female, respectively. The age-standardized prevalence rates of MS were 9.93% in total, 13.58% in male and 6.11% in female. The prevalence rates of MS in male was higher than that in female (P0.05). The prevalence rates of components of MS were 43.31% for obesity, 30.08% for hypertension, 25.79% for hypertriglyceridemia and 16.28 % for hyperglycosemia. Among the four factors above, there were about 65% subjects who had at lest one abnormal factor according to the CDS criterion. Conclusion There were no differences in the prevalence rates of MS between the Uygur and Han populations. However, the prevalence rate of MS in male was higher than that in female. More than half subjects had at least one abnormal metabolic factor.

One-day-old unvaccinated chicks were inoculated with serotype I virulent strain GA and vaccine strain CVI988, serotype III vaccine strain HVT o f Marek's disease viruses(MDV). By using an indirect immunofluorescence assay of suspensions of peripheral blood mononuclear cells(PBMC) with monoclonal antibo dies(MAb) BA4 and BD8 specific to glycoprotein B of MDV, The dynamic course s of vir emia levels for each of 3 strains from 4 days to 45 days postinfection (PI) were determind. Viremia for virulent strain GA-infected chickens were detected from 4 days PI until days before death of infected chickens, it got its peak at abou t 14 days PI. Viremia in serotype 1 vaccine CVI988-inoculated chickens were mea sured between 4 to 22 days PI, it could be detected from 4 days PI and ended at 18 days PI, it got its peak at 8 days PI. For serotype 3 vaccine HVT-inoculated chickens, viremia could be detected beween 4 to 14 days PI, its peak happened a t about 6 days PI. Such IFA with MAbs BA4 and BD8 could be used to evaluate qu al ity of vaccination process in chicken flocks. The differential dynamic courses o f viremia for different strains may be used to diagnose virulent MDV infection i n vaccinated flocks. The viremia levels measured by IFA with the MAbs and co-cu ltivation assay for plague forming unit(PFU) were compared. The results indicate d that IFA assay of PBMC suspension was more sensitive and specific than co-cu ltivation assay, i.e. viremia levels measured by IFA were 30 to 100-fold higher than that by plague-forming assay in CEF for the same sample.
