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 To study the clinical features,differential diagnosis and treatment of caesarean scar pregnancy (CSP) with sonographic mass.Methods A retrospective analysis was performed on 39 patients of CSP with sonographic mass undergoing treatment in Peking Union Medical College Hospital from 2005 to 2012.14 cases with misdiagnosis of gestational trophoblastic neoplasm,among 4 cases were administered by chemotherapy with methotrexate (MTX),cisplatin,fluorouracil (5-FU) and dactinomycin.According to treatment methods,39 cases were divided into five groups: 3 cases in methotrexate,16 cases in dilation and curettage,15 cases in excision of CSP lesion via laparoscopy,6 cases in excision of CSP lesion via laparotomy,and 4 cases in transabdominal hysterectomy (TAH).Results (1)Clinical characteristics: the mean age was (33 ± 5) years old.Five patients had undergone two prior caesarean sections.The median interval from the last caesarean delivery to CSP was 4 years.Thirty-five cases presented vaginal bleeding or abnormal serum β-hCG level from 5 cases with medical abortion,9 cases with artificial abortion and 21 cases with dilation and curettage.The sonography showed cystic-solid or solid mass with mixed echoes in the lower segment of anterior uterine wall,surrounded by peritrophoblastic vasculature.(2) Treatment outcome: diagnosis of gestational trophoblastic neoplasm was suspected or made in 20 patients,four of whom were even treated by chemotherapy.MTX therapy was given to 3 patients,2 of whom were cured.Dilation and curettages were given to 16 patients,11 of whom were cured.8 patients underwent curettage with sonographic guidance after uterine artery embolism,and 8 patients with laparoscopic or hysteroscopic guidance.All of 15 patients underwent excision of CSP lesion via laparoscopy were cured.4 patients were treated by TAH.(3) Time of in hospital and operation:in laparoscopy group,the average hospitalization days were (3.5 ± 1.6) days,the average operation duration was (54 ± 16)minutes.In laparotomy group,the average hospitalization days were (9.7 ± 5.8) days,and the average surgical duration was (87 ± 15) minutes.It reached significant difference (P ＜ 0.05).Conclusions CSP with sonographic mass was the consequence of continued growth of residual pregnancy mass after incomplete abortion or curettage of CSP with gestation sac.The similar sonographic image might lead to misdiagnosis.Individual therapy was recommended.Excision of CSP lesion via laparoscopy might be the primary option for its advantages in differential diagnosis,caesarean scar defect repair and successful ratio.
