This study aimed to construct recombinant adenovirus expressing Epstein-Barr nuclear antigen 1 (EBNA1) against nasopharyngeal carcinoma (NPC). The C-terminal region fragment of the ebna1 gene of Epstein-Barr virus was amplified from the standard strain B95-8 by polymerase chain reaction (PCR). The gene fragment was inserted into the pDC316 shuttle plasmid using the EcoRI and BgIII restriction enzyme sites. The pDC316-ebna1 shuttle plasmid and pBHG helper plasmid were cotransfected into HEK293 cells after sequencing. The soluble protein was extracted from HEK293 cells, which caused apparent cytopathic effects. The transcription and expression of the ebna1 gene were confirmed using flow cytometry and Western blotting. rAd-ebna1 titers were measured by the TCID50. rAd-ebna1 was injected into BALB/c mice at a dose of 2 x 10(8) VP per mouse, EBNA1 epitope-specific responses were measured at 1st, 2nd, 4th and 8th weeks post-immunization. The target fragment of ebna1 (939 bp) was obtained by PCR, and was in consensus with the sequence from the standard strain B95-8. Cytopathic effects were observed after the pDC316-ebna1 shuttle plasmid and pBHG helper plasmid were cotransfected into HEK293 cells. rAd-ebna1 was successfully recombined in HEK293 cells. EBNA1 protein was detected in HEK293 cells, rAd-ebna1 titers reached 10(8) TCID50/mL. Specific responses to CD4+ epitopes of EBNA1 were detected in the immunized mice. In conclusion, rAd-ebna1 was successfully constructed and induced specific responses to CD4+ epitopes of EBNA1 in immunized mice.

Objective To investigate the meaning of expression of apoptosis related molecules NFKBp65 and p53 and GPX1-mRNA in patients with Keshan disease(KSD).Methods Sixteen chronic Keshan Disease patients were enrolled in KSD group according to electrocardiogram,chest X ray film and clinical examinations on 15,September in 2009,and 23 healthy people were included in control group from physical examination taken in The Second Affiliated Hospital of Xi'an Jiaotong University.Fresh blood(5 ml)was collected from antecubital vein of all subjects in the fasting state.Total mRNA and protein of blood sample were isolated using Trizol.GPX Assay Kit was used to detect GPX enzyme activity,and GPX1-mRNA expression was determined by SYBR Real-Time PCR.Meanwhile,expression of apoptosis related molecules NFKBp65 and p53 were determined by Western blot.Results GPX enzyme activity decreased significantly in KSD group[(108.61±14.10)U]compared with control group[(122.78±11.89)U,t=2.874,P<0.05],GPX1-mRNA level of KSD group(0.553±0.299)notably KSD group(0.802±0.057)compared with control group[(1.065±0.355),t=6.829,P<0.01].p53 increased in KSD group(1.604±0.191)compared with control group[(1.137±0.186),t=3.033,P<0.05].Conclusiom Decreased GPX1-mRNA expression may result in lower GPX enzyme activity of patients with KSD.Thus oxidative damage increases and cadioeyte apoptosis is activated by activating apoptosis signal pathway.

Objective To explore the value of color doppler ultrasonography by bed side in the early diagnosis of HIE in full term neonates.Methods The changes of cerebral parenchymal and cerebral arterial blood stream parameter on 35 cases of neonates clinically diagnosed HIE of mild and moderate degree and 40 cases of normal newborns on the 24,48 and 72 hours after birth were observed by color doppler ultrasonography by bed side.Results 1.The cerebral parenchyma was even echo in normal newborns,but it was maldistributed and reinforced in mild asphyxia neonates and it was more serious in moderate degree.The echo of cerebral parenchyma in mild degree was near normal in 48 hours after birth,while the echo of cerebral parenchyma in moderate degree was still maldistributed and reinforced in 48 and 72 hours after birth.2.There was obvious changes in the cerebral arterial blood stream parameter and hemodynamics of the asphyxia newborns compared with normals.The systolic peak velocity(Vs)and end diastolic velocity(Vd)of the cerebral arteries in mild and moderate degree were obviously lower than that of control group in 24,48 hours after birth(Pa0.05).3.Resistance index(RI)of the cerebral arteries in mild and moderate degree were higher than that of control group in 24,48 hours after birth(Pa0.05).Conclusion Color doppler ultrasonography by bed side is a convenient,noninvasive method for diagnosing HIE.

Objective To study the difference of expression of proteins in pancreatic cancer and adjacent fissue.Methods Proteomes of eight pairs of pancreatic ductal adenocarcinoma tissue samples and adjacent tissue samples were obtained by high resolution two-dimensional gel electrophoresis(2-DE).Comprehensive analyses of proteins were focused on total protein spots exhibiting statistical alternations between the two groups.Protein identification was done by peptide mass fingerprinting with tandem mass spectrometry(MS/MS).In addition,Western blotting and immunohistochemistry were performed to verify the expression of certain candidate protein.Results A total of 28 protein spot-features were found to be significantly increased and 17 significantly decreased in tumor tissues.Thirty of these protein spots were identified,which included enzymes,antioxidant proteins,signal transduction proteins,calcium-binding protein,structural proteins,chaperones and others.Western blotting and IHC further validated up-regulated expressions of one candidate protein(annexin II)in tumor tissues.Conclusions The analysis of proteomics with 2-DE on human tissue is a useful method for discovering valuable cancer marker candidates.These differential expressed proteins may serve as biomarkers for early detection and therapeutic targets to pancreatic cancer.

Objective To investigate the damaging traits of cognitive function in first episode depression patients with the assessment of neuropsychological status ( RBANS) and Stroop Color-word Test. Methods Two hundred and thirty first-episode depression patients as experimental group and one hundred and seventy-eight health person as control were evaluated separately by repeatable battery for the RBANS and Stroop Color-word Test. Results In Stroop Color-word Test,the time required for completing the words,color,double-word,two-color in depression patients ( (14.37 ±6.65)s,(21. 58 ±8. 70) s,( 16. 56 ±8. 23)s, (37. 88 ± 13. 67) s) were longer than the control group ((12.38 ±3.34)s, (18.01 ±5.51) s, (14. 17 ±4. 37) s, (32. 87 ± 10.28) s). The difference between the two groups was found in cognitive function in first episode depression patients (P ＜ 0.05). The scores of color interference and meaning interference were no difference between the two groups (P＞0.05) . The patients'scores of the RBANS test in all items( (72.19 ± 17.22), (80.89 ± 15.29), (82.00 ± 16.37) , (98.74 ± 17.01) ,(82.09 ± 14.62) )were significantly poorer than those in healthy controls. Compared with control group, scores of the scales were significant difference between two groups. Pearson correlation analysis showed that RBANS total score and five factors had no correlation with HAMD total score and factors. It positively correlated with education level (P＜0.05) ,but not with sex (P＞0.05). Immediate memory,verbal function,delayed memory in five factors and RBANS total score negatively correlated with age and course of disease respectively, but breadth of vision,attention were not did(P＜0.05). Conclusion First-episode depression patients suffer from more serious and comprehensive damage of cognitive function such as memory,attention,executive function.

Objective To compare the fast blood flow density (FBFD) of intermediate choroid between endogenous Cushing syndrome (ECS) patients and healthy control subjects.Methods Thirteen eyes of 7 eligible ECS patients (ECS group) and 13 eyes of 7 gender,age,axial length matched healthy volunteers (control group) were enrolled in this study.For each subject,macular radial scan with swept source optical coherence tomography (SS-OCT) was performed and subfoveal choroidal thickness (SCT) was measured.Then 3.0 mm× 3.0 mm macular scan with SS-OCT angiography was performed,and selected blood flow image at intermediate choroid level or 1/2 SCT beneath Bruch membrane.The grayscale images were then binarized for the analysis of FBFD.Results The SCT in ECS group was (394.7±77.7) μm,which was significantly thicker than (332.1 ± 68.1) μm in control group (t=2.923,P=0.008).The FBFD of intermediate choroid in ECS group were (76.35± 14.46)％,which were significantly greater than (63.57± 13.42)％ in control group (t=2.775,P=0.01).Conclusion ECS patients had increased FBFD at intermediate choroid level compared with healthy controls.

OBJECTIVETo observe the effect of periodontal initial therapy together with Chinese herbal compound for clearing heat and detoxification (Abbr. TCM) on the levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 beta (IL-1 beta) in gingival crevicular fluid (GCF) of patients with chronic periodontitis (CPD).

METHODSThirty-four teeth of 24 patients with CPD were randomly assigned to the control group (17 teeth of 11 patients) and the treated group (17 teeth of 13 patients), they were treated for 8 weeks with periodontal initial therapy, but TCM was given additionally to the treated group. The GCF of the observed teeth was collected at the time before initial therapy (datum line) and at 2 and 8 weeks after treatment. At the same time, the clinical parameters, including probing depth (PD), clinical attachment loss (CAL), and bleeding on probing (BOP) were recorded, and the levels of TNF-alpha and IL-1 beta in GCF were measured by radioimmunoassay.

RESULTSThe levels of TNF-alpha and IL-1 beta in GCF after treatment were significantly lowered in all patients as compared with those before treatment (P<0.01), while PD, CAL and BOP showed significant reduction (P<0.01). After treatment, TNF-alpha and IL-1 beta levels in the treated group were lower than those in the control group (TNF-alpha: 2.5551 +/- 1.0157 microg/L vs 3.4341 +/- 1.0762 microg/L, IL-1 beta: 0.1335 +/- 0.0216 microg/L vs 0.1471 +/- 0.0169 microg/L; P<0.05).

CONCLUSIONTCM could enhance the effect of periodontal initial therapy in lowering TNF-alpha and IL-1 beta levels, which was attributed to reducing the inflammatory reaction of periodontal tissues.
