Objective To study the effects of deoxycytidine (5-aza-2 deoxycytidine, DAC) on DNA Methylation state and expression of mRNA and protein of pl6 gene in human squamous lingual carcinoma SCC-9 cells in vitro. Methods The SCC-9 cells were divided into four groups, group 0, 1, 2 and 3 which processed using three gradients concentration of DAC. The group 0 without DAC was as the control group. Q-MSP was used to detect the state of methylation of the p16 in SCC-9 cells treated by DAC after 48 hours. Real-time fluorescence quantitative PCR was used to detect mRNA expression level changing of the p16 in SCC-9 cells treated by DAC. Immunohistochemical method was used to detect the expression of p16 protein. Results The hypermethylation and non-methylated p16 gene in SCC-9 was mixed with the results of Q-MSP. The results of Real-time PCR showed that mRNA expression of p16 in SCC-9 cells which treated by the different concentration of DAC for 48 hours was higher the control group. And difference was statistically significant (P < 0.05). The high expression of p16 protein was found in the experimental group with immunohistochemical method. Conclusion The p16 gene methylation states of SCC-9 may be suppresses and the recovery of mRNA and protein expression of p16 gene must be prompted by DAC.

ObjectiveTo explore the effect of acupuncture combined with training of the modified rehabilitation apparatus on upper limb motor function of patients with ischemic stroke.Methods86 patients with ischemic stroke were divided randomly into the treatment group ( treated by acupuncture combined with training of the rehabilitation apparatus) and the control group (treated by simple acupuncture). The upper limb motor function of two groups was evaluated by Fugl-Meyer Assessment (FMA) before and after treatment.ResultsAfter 28 days treatment, scores of FMA of two groups were all raised significantly, but it was significantly greater for the treatment group than the control group (P<0.01).ConclusionIt is shown that acupuncture combined with training of the rehabilitation apparatus can improve the upper limb motor function and activity of daily living of patients with ischemic stroke.

Objective To investigate the expression of engulfment and cell motility protein 1 (ELMO1) in hepatocellular carcinoma(HCC) and its effects on cell migration.Methods The expression of ELMO1 in HCC cell lines and HCC tissues was assessed by Western blot.We used transient transfection with an ELMO1 expressing vector to over-express ELMO1 protein in SK-HEP-1 cells.Over-expression of ELMO1 was confirmed by Western blot.siRNAs specific to ELMO1 (ELMO1 siRNA) were used to knockdown ELMO1 expression.Rho Family Small GTPase Activation Assay, Western blots, transwell assay were used to determine the migration potential of cells.Student's test was employed for statistical analysis.Results The expression of ELMO1 protein was obviously up-regulated in HCC tissues and cell lines (P<0.05).Over-expression of ELMO1 promoted cell migration in SK-HEP-1 cells, while knock-down of ELMO1 showed the opposite effect.Conclusion ELMO1 up-regulation significantly correlates with cell migration in hepatocellular carcinoma.

DNA from 32 cases of tongue squamous cell carcinoma(TSCC)specimens and the neck lymph node metastasis specimens were processed by bisulfite treatment.The methylation of the specimens was examined by Q-MSP amplification.The consistency of p1 6 methyla-tion of primary TSCC with that of lymph node metastasis tumor was 90.62%(P <0.05).We assumed that p1 6 gene promoter CpG island methylation rates in primary TSCC and metastatic lymph nodes are consistent,p1 6 gene methylation status can be a methylation predictor be-tween premary and lymph node metstasized TSCC.

Objective To study the risk factors for children with acute central nervous system(CNS)viral in-fection,so that pediatrician may identify children with poor prognosis at early stages of the disease,and provide them with a theoretical basis for clinical treatment. Methods The clinical data of a cohort patients of acute CNS viral infec-tion who were hospitalized at the First Affiliated Hospital of Fujian Medical University between January 2010 and June 2013 were retrospectively collected and analyzed. According to Glasgow outcome scale on discharge,children were di-vided into good prognosis group and poor prognosis group. Clinical data and outcomes were analyzed by using univariate analysis and binary Logistic regression multivariate analysis. Results Three hundred and one cases were enrolled,278 (92. 36% )patients were assigned to the good prognosis group,and 23(7. 64% )patients were assigned to the poor prognosis group. By univariate analysis,the patients in the poor prognosis group had longer duration of sickness before admission,longer time of fever,lower white blood cell count in cerebrospinal fluid,a relatively lower calcium level,con-scious disturbance at the early stage,multiple seizures,convulsive status epilepticus,meningeal irritation sign,muscle weakness,severe changes in electroencephalogram(EEG),and abnormal neuroimaging findings(computed tomography or magnetic resonance imaging,or both)had significant differences between the good prognosis group and the poor short - term outcome groups(all P < 0. 05). By binary Logistic regression multivariate analysis,factors indicating a poor prognosis during the early stage were conscious disturbance at the early stage(0R = 4. 885,95% CI:1. 523 - 15. 670, P = 0. 008),multiple seizures(0R = 6. 352,95% CI:1. 905 - 21. 178,P = 0. 003),severe changes in EEG( 0R =4. 269,95% CI:1. 708 - 10. 666,P = 0. 002),and abnormal neuroimaging findings( 0R = 9. 740,95% CI:2. 360 -40. 192,P = 0. 002). Conclusions Conscious disturbance at the early stage,multiple seizures,severe changes in EEG and abnormal neuroimaging findings are risk factors for acute viral infection of CNS in children.

Objective To assess the feasibility of heterogeneous acellular dermal matrix(ADM)seeded with adipose derived stem cells(ADSC)for urethroplasty in a rabbit model.Methods ADSC were isolated from a rabbit and expanded in vitro,then identified by flow cytometry.We seeded ADSC onto the ADM and made it into tissue-engineered urethra.12 male rabbits were removed 1 cm urethra and divided into experiment group and control group.There were 6 rabbits in each group.Reconstructed urethra with tissueengineered urethra was used in experiment group,while unseeded ADM were used in control group.Urethrography was performed at 6 months after surgery.The animals were scarified at 3 and 6 months after surgery and the repaired urethra were harvested.H&E staining and immunohistochemical staining were performed with cytokeratin AE1/AE3 and smooth muscle desmin makers.Results The morphology of isolated ADSC was with long spindle cross-links,and had multicentral growth.Flow cytometry showed that the ADSC expressed CD166,CD105,CD90 and CD44,but not expressed CD45 and CD13.The cells could growth well on the ADM and showed good biocompatibility with it.All animals could void normally,urethrography showed there was no significant stenosis.3 months after surgery,the experiment group appeared regenerated smooth muscle but not in the control group,both groups did not regenerate urothelium.At 6 months urothelium and smooth muscle cells could be observed in the experiment group,but only the smooth muscle was evident in the control group.Conclusions By applying tissue engineering methods,we can seed the ADSC onto the heterogeneous ADM and make it into tissue-engineered urethra,which can help improve the reconstructive effect of urethra.

AIM: To investigate the inhibitory effect of Chinese medicine Jinan injection(JA) on Lewis lung cancer (LLC) in mice. METHODS: The C 57 BL/6J mice with Lewis lung cancer(LLC) were divided into normal saline(NS), Jinan high dose (JAH), Jinan middle dose (JAM), Jinan low dose (JAL) and cyclophosphamide(CTX) groups. The body weight changes and inhibitory rate of LLC in each group were observed. In addition, flow cytometry and TUNEL were used to detect the anticancer mechanism of Jinan. RESULTS: The body weights were increased significantly in JA-treated groups vs CTX and the resistant rate was 45.79%, 40.90%, 32.48% and 98.96%, respectively. The apoptotic rate was 24.19%, 14.95% and 13.93% in JAH, JAM and JAL, respectively, and the Jinan induced apoptosis of LIC in a dose-dependent manner.CONCLUSION: Jinan injection inhibites the growth of LLC, and the apoptosis induction may be one of mechanisms that Jinan treates LLC in mice.
