Objective To observe the effect of transduetion of human wild type gene(wt-p53) mediated by recombinant adenovirus on cell growth, cell cycle and apoptosis of neuroblastoma (NB) cell line SH-SY5Y. Methods The NB cell line SH-SY5Y were transfected by recombinant adenovirus with green fluorescent protein(Ad-GFP). The suitable muhiplieity of infection (MOI) was determined after trans-fer efficiency was tested by flow cytometry (FCM). Both recombinant adenovirus(Ad) and recombinant adenovirus mediating wt-p53 gene (Ad-p53) were transfected into SH-SY5Y cells. SH-SY5Y cells without any transfection were used as blank group. The p53 protein expres-sion was validated by Western blot. Cell number was counted and growth curve was drawn. Both cell cycle and apoptesis were detected by FCM. Results The results indicated that the transfer efficiency of recombinant adenovirus to SH-SY5Y was satisfied, and 100 MOI was suitable. After transfection with Ad-p53, p53 protein was high expressed. Cell growth were inhibited, apoptosis and cell cycle arrest were in-duced in p53 gene transfeetion group. Conclusions Our results indicate that clinical application of the in vitro p53 gone modified tumor cell vaccine might be feasible and effective in clinical treatment of NB.

ObjectiveTo observe the effect of co-stimulated factor B7-1 and granulocyte-macrophage colony-stimulating factor(GM-CSF) genes mediated by recombinant adenovirus on immunogenicity of neuroblastoma(NB)cell line SH-SY5Y.MethodsAfter NB cell line SH-SY5Y was transfected with recombinant adenovirus mediating green fluorescent protein(Ad-GFP) in different multiplicity of infection(MOI),the transfer efficiency was tested by flow cytometry(FCM).SH-SY5Y cells were transfected separately with recombinant adenovirus,recombinant adenovirus mediating B7-1 and GM-CSF genes or only B7-1 gene,and they were named as Ad,B7-GM and B7 group.The cells which were not transfected were named as SH group.The protein expression of B7-1 and GM-CSF were detected by using FCM and enzyme linked immunosorbent assay(ELISA).Peripheral mononuclear cells were separated and purified with Ficoll density gradient centrifugation.Cpm and cytokine(IFN-? and IL-2) secretory were evaluated by mixed lymphocyte culturing with different ratio(5 to 1 and 10 to 1) on target cells and effect cells.ResultsTransfer efficiency of recombinant adenovirus to SH-SY5Y was high.After transfection,B7-1 and GM-CSF genes were expressed.Proliferation of lymphocytes was stimulated and cytokine increased vigorously in B7-GM group and B7 group,and the effect in B7-GM group was stronger than that in B7 group.And the effect in ratio 5 to 1 group was stronger than that in 10 to 1 group.ConclusionsB7-1 and GM-CSF genes have synergistic effect.After transfection with recombinant adenovirus mediated B7-1 and GM-CSF genes,the immunogenicity of SH-SY5Y is greatly enhanced.

AIM: To investigate the infection factors,diagnosis and treatment of endophthalmitis after intraocular foreign body injury.METHODS: Totally 256 cases with intraocular foreign bodies including the occurrence of endophthalmitis in 42 cases were analyzed retrospectively.RESULTS: The incidence of endophthalmitis after intraocular foreign body injury was 16.4%.Posterior segment foreign bodies and combined with traumatic cataract were the risk factors of endophthalmitis after intraocular foreign body injury (all P<0.05).Intravitreal injection of vancomycin hydrochloride and ceftazidime in the treatment of intraocular foreign body injury reduced the incidence of endophthalmitis (P<0.05).Types and sizes of intraocular foreign bodies,the time of extraction and the condition of wound had no significant effect on the incidence of endophthalmitis (all P>0.05).Vitrectomy was the main treatment of endophthalmitis.CONCLUSION: Posterior segment foreign bodies and combined with traumatic cataract were the risk factors of endophthalmitis after intraocular foreign body injury.It should be kept the integrity of the posterior capsule of lens in traumatic cataract surgery.Intravitreal injection of vancomycin and ceftazidime is recommended in emergency surgery.Vitrectomy should be performed as soon as possible when confirmed endophthalmitis.

Objective To observe and compare the regulating effect between electroacupuncture and sham electroacupuncture on the symptoms of menopausal transition and levels of estradiol (E2), follicle-stimulating hormone (FSH), and luteinizing hormone (LH), for evaluating the clinical efficacy of electroacupuncture in mitigating the relevant symptoms of menopausal transition. Method Thirty eligible subjects with menopausal transition were randomized into a treatment group and a control group, 15 cases in each group. The treatment group was intervened by electroacupuncture at the ordinary acupoints, while the control group was by electroacupuncture at non-meridian points. The E2, FSH, and LH contents were detected after intervention and at the 20th week during the follow-up study, the flush score and Menopause Rating Scale (MRS) were evaluated respectively after 4-week and 8-week treatment and at the 20th week and 32nd week during the follow-up study, and the safety of electroacupuncture was also estimated.Result The flush and MRS scores were significantly changed after 4-week and 8-week treatment and at the 20th week and 32nd week during the follow-up study in both groups compared to that before the treatment in the same group (P<0.01,P<0.05). There was a significant difference in comparing the changes of MRS score after 8-week treatment between the two groups (P<0.01). There were significant differences in comparing the changes of flushing scores between the two groups after 8-week treatment and at the 20th week and 32nd week during the follow-up study (P<0.01). The serum levels of E2, FSH, and LH were significantly changed in the treatment group after 8-week treatment (P<0.05). There were significant differences in comparing the changes of FSH and LH levels between the two groups after 8-week treatment (P<0.05). The difference in comparing the change of serum E2 level between the two groups at the 20th week during the follow-up study was statistically significant (P<0.05). Conclusion Electroacupuncture can improve the flushing intensity and produce a benign regulation on the relevant hormone levels in menopausal transition, though this regulation is insignificant when the treatment terminates.

Objective To analyze the prevalence of human papilloma virus(HPV) and the relationship between HPV and vaginal environment in puerperium women.Methods One thousand and twenty-nine cases puerperium women were detected for HPV subtype by using nucleic acid flow-through hybridization.Patients with HPV positive had been considered as observe group and the rest as control.The prenatal infection of HPV of HPV-DNA positive and negative postpartum puerperium women, and the vaginal cleanliness of prenatal and postpartum were analyzed.Results In 1 029 cases puerperium women, the total HPV-DNA positive rate was 10.30％(106/1029) ,and high risk infection rate was 95.65％ (110/115).The rate of HPV positive before pregnant in HPV positive group (46.51％, 40/86) was higher than that in HPV negative group (9.09％, 10/110).There was significant difference of vaginal environment in the two groups (x2 =36.567, P＜0.05).In HPV-DNA positive and negative women during the puerperium vaginal cleaning degree of Ⅰ , Ⅱ ratio prenatal respectively were 56.98％ (49/86) and 76.36％ (84/110), and the difference was significant (x2 =8.317, P ＜0.05).Postpartum to 45.35％ (39/86) and 60.00 (66/110), and the difference was significant (x2 =3.941, P＜0.05).Conclusion The HPV infection of pregnant women are easy to getagain.There is relevance between HPV infection and vaginal environment.

Objective To study the effect of clopidogrel on different CYP2C19 genotypes and platelet reactivity in acute cerebral infarction patients with antiplatelet aggregation.Methods Four hundred and seventy-four cases of cerebral infarction patients in Beijing Tiantan Hospital Affiliated to Capital Medical University from April 2015 to April 2016 were collected.CYP2C19 genotype was determined,and the genotype was divided into the wild type group,the heterozygous type group and the mutant homozygous group.Platelet aggregation inhibition rate(ADP%) and platelet reactivity index induced by ADP were detected.Patients were divided into clopidogrel resistance group(group CR) and non resistant group according to whether ADP% was less than 30.SPSS 16.0 statistical software was used for statistical analysis,the comparison between groups using independent samples t test,chi square test and multivariate analysis using Logistic regression analysis,when P<0.05 difference was statistically significant.Results Among the 474 patients,204 cases(43.04%) were divided into wild-type group,and 204(43.04%) and 66(13.92%) were divided into the mutant heterozygous group and mutant homozygous group.In Chi square test analysis,clopidogrel resistance group and non resistance group CYP2C19 genotype distribution was significantly different(χ2=6.658,P=0.036).CR group angle(α) values((68.87±5.47)°) and MA((66.77±6.25) mm) were higher than that of CS group ((66.55±6.05)° and (63.30±5.66) mm,t=2.199,3.387,P=0.029,0.001).The multivariate logistic regression analysis showed that OR of angle level was 1.028,95%CI was 0.929-1.137 (P=0.595);OR of Ma level was 1.561,95%CI was 0.785-0.970 (P=0.012).Conclusion The effect of clopidogrel on platelet aggregation in patients with acute cerebral infarction is decreased by CYP2C19 gene mutation.CYP2C19 mutant allele is a risk factor for clopidogrel resistance.Angle (α) value and MA value are the risk factors for the diagnosis of CR in the patients with acute cerebral infarction,and the risk of clopidogrel resistance increased when the patients′ Angle (α) value and the value of MA increased.MA value as a predictor of CR and the screening tool has a certain value.
