Alteration of metabolism and epigenetic status are two new focuses in the field of cancer re -search.Recently,more and more reports have demonstrated that the changes of both metabolic enzymes and al -tered epigenetic status have close interrelationship with the pathogenesis and development of gliomas in human . We discuss here the effects of altered metabolic enzymes on epigenetic status in gliomas based on two important altered metabolic enzymes ,with the aim to unlock the molecular mechanism on how gliomas occur and progress . This newfound molecular mechanism of how altered metabolic enzymes impact on epigenetic status in gliomas may contribute to the identification of novel therapeutic targets to gliomas in the future .

Objective To provide the basis for the study of HPV16 E5 gene inthe pathogenesis of oral squamous cell carcinoma by constructing three lentiviral vectors expressing HPV 16 E5, E6 or E7 oncogene and transfecting o-ral epithelial cells with the vectors.Methods HPV16 E5, E6 or E7 oncogene was amplified using PCR and liga -ted into the lentiviral vector pLVX-AcGFP-N1 respectively to construct vectors pLVX -AcGFP-E5, pLVX-AcGFP-E6 and pLVX-AcGFP-E7, then respectively cotransfected 293T cells with packaging plasmids , viral supernatant was collected to respectively transfect oral epithelial cells .Afterpuromycin screening,oral epithelial cells with HPV 16 E5, E6,or E7 oncogene transfection were constructed , then reverse transcription PCR and western blotassays were performed for verifying HPV16 E5, E6 or E7 expression.Results pLVX-AcGFP-E5, pLVX-AcGFP-E6 and pLVX-AcGFP-E7 were successfully constructed, oral epithelial cells expressing HPV 16 E5, E6 or E7 oncogene wereacquired, HPV16 E5,E6 or E7 expression was confirmed in oral epithelial cellsthrough reverse transcription PCR and western blot assays.Conclusion Three lentiviral vectors expressing HPV16 E5, E6 or E7 oncogene can successfully infect oral epithelial cells .

Objective To investigate the effects of 25‐hydroxy vitamin D [25(OH)D] status on the pregnancy outcome in the second and third trimester pregnant women living .Methods A total of 143 pregnant women (12 -42 weeks gestational age) were participated in the study .Their serum 25(OH)D concentrations were detected by liquid chromatography‐mass spectrometry method .Finally ,vitamin D status was assessed according to sufficiency group(n= 32) ,inadequacy group(n= 49) ,insufficiency group(n=51) and deficiency group(n=11) .Retrospective analysis were adopted to follow up the pregnancy outcome of pregnant women .Results (1)The average serum 25(OH)D level was(22 .49 ± 9 .51)ng/mL in the second and third trimester of pregnancy . (2)Abortion rate were 3 .1% (1/32) in sufficient group ,2 .0% (1/49)in inadequacy group ,11 .8% (6/51) in insufficiency group , 36 .4% (4/11) in deficiency group ,fetal distress incidence were 3 .1% (1/32) ,8 .2% (4/49) ,11 .8% (6/51) ,36 .4% (4/11) in each group .Abortion ,fetal distress rate were higher in deficiency group compared with the other three groups(P<0 .05) .(3)Bacterial vaginosis incidence were 0(0/32) ,4 .1% (2/49) ,13 .7% (7/51) ,27 .3% (3/11)in each group ,deficiency group and insufficiency group were higher(P<0 .05) .(4)Otherwise ,the gestation period were (39 .48 ± 1 .44) weeks in sufficient group ,(39 .00 ± 1 .70) weeks in inadequacy group ,(38 .09 ± 2 .01) weeks in insufficiency group ,(37 .29 ± 0 .49) weeks in deficiency group ,pregnancy cycle was significantly shorter when 25(OH)D<20 .00 ng/mL (P<0 .05) .Conclusion Vitamin D deficiency in pregnant women could increase the risk of abortion ,fetal distress ,bacterial vaginosis ,and significantly shorten the gestation period .

Objective:To observe the clinical curative effect of long-time needle retaining at Baihui(GV20)combined with multidirectional point-toward-point needle insertion with needle shaking at Fengchi(GB20)for the treatment of cervical vertigo(CV)and its influence on the blood flow velocity of vertebrobasilar arteries. Methods:Seventy patients with CV were randomly divided into a treatment group(35 cases,1 dropout)and a control group(35 cases,2 dropouts)according to the random number table method.Those in the treatment group were treated with long-time needle retaining at Baihui(GV20)combined with multidirectional point-toward-point needle insertion with needle shaking at Fengchi(GB20),and those in the control group were treated with conventional acupuncture.The treatment was performed every other day,7 sessions as a treatment course,for a total of 2 courses.The clinical efficacy was compared between the two groups by observing changes in the evaluation scale for symptoms and functions of cervical vertigo(ESCV)and the mean blood flow velocity(Vm)of vertebrobasilar arteries. Results:The total effective rate and the cured plus markedly effective rate were 91.2%and 79.4%,respectively,in the treatment group,versus 78.8%and 54.5%in the control group,respectively,with a statistically significant difference in the cured plus markedly effective rate between the two groups(P<0.05).The ESCV score and the Vm of vertebrobasilar arteries in the two groups improved significantly after treatment.The Vm of the left vertebral artery(LVA),right vertebral artery(RVA),and basilar artery(BA)increased in patients with low and normal flow velocities(P<0.05),and the Vm of the LVA,RVA,and BA decreased in patients with a high flow velocity(P<0.05);the results in the treatment group were significantly better than those in the control group(P<0.05). Conclusion:Long-time needle retaining at Baihui(GV20)combined with multidirectional point-toward-point needle insertion with needle shaking at Fengchi(GB20)can significantly reduce the clinical symptoms of CV and regulate the blood flow rate of vertebrobasilar arteries bidirectionally,and thus is an effective therapy for CV.

Objective Monkey B virus(BV), also known as Cercopithecine herpesvirus 1,is an important zoonotic pathogen.According to the national standard, antibodies are detected using BV as an antigen.However, the preparation of BV antigen is very stricted due to biosafety issues.Therefore, in this study, we used alternative antigens to detect the BV antibody by serological assay and verified their specifity and sensitivity.Methods A total of 135 blood samples from rhesus monkeys were tested by two ELISA method (BV and HVP2) and enzyme immunosorbent assay (EIA)method.The positive and suspicious samples were verified by immuno-fluorescence assay (IFA), Western blot and immunoblotting technique using HSV-1 gC1 purified glycoprotein as an antigen.Results The positive rates of HVP2-ELISA, BV-ELISA and HSV-1-EIA were 32.6%, 37.8% and 34.8%, respectively.Consistant result of the three detection method accounted for 91.1% (123/135), and the positive result were confirmed by IFA And WB.There were 12 suspicious samples,in which 33.3% (4/12) were verified to be positive.Conclusions Compared with BV antigen, the sensitivity and specificity of the alternative antigen HSV-1 are moe close than HVP2.Positive and suspicious samples should be verified by several method to avoid missed detection.

Objective To assess the agreement of different endoscopy grading or scoring systems for inflammatory bowel diseases(IBD)including ulcerative colitis(UC)and Crohn's disease(CD).Methods A standardized table was prepared based on the searches for endoscopic grading or scoring systems on Medline and Chinese Biomedical Database,the data of 80 patients with UC and 31 with CD.who underwent colonoscopy in Shanghai Renji hospital from June 2006 to February 2007,were evaluated with each system by two physicians independently.Data were analyzed with SPSS 13.0.Results Six endoscopic grading and scoring systems of UC and three of CD were included for evaluation.For the systems of UC and CD,Kendall's coefficients of concordance were 0.71(P<0.01)and 0.34(P<0.01),respectively.There was no significant differenee between every two systems for UC.Nonetheless.Spearman's correlation coefficient between Chinese Grading System of Crohn's Disease(CGSCD)and Crohn's Disease Endoscopic Index of Severity(CDEIS)was 0.32(P=0.08).Significant differences in frequencies were detected in endoscopic systems for UC by Kruskal Wallis test(P<0.01).Conclusion There is satisfactory concordance among the endoscopic grading and scoring systems of UC,while CGSCD needs further improvement.Furthermore,Jeroen elassifieation inclines to severe category,while modified Baron scale tends to be a mild one.
