Objective:To study the expression of NF-?Bp65 and bcl-x L gene in pancreatic carcinoma and their clinical significance.Methods:The expressions of NF-?Bp65 and bcl-x L protein in 52 pancreatic carcinoma were studied by immunohistochemistry,and their relationship to clinical pathology were analyzed.Results:The positive rates of NF-?Bp65 protein and bcl-x L protein in pancreatic carcinoma were 63.5% and 73.1% respectively,and which were higher than those of normal pancreatic tissues.The expression of NF-?Bp65 was related to tumor diameter,TNM stage and lymph node metastasis,and had no relation with the extent of differentiation and type of pathology.There was positive correlation between NF-? Bp65 and bcl-x L expression.Conclusion:NF-? Bp65 may be an important oncoprotein,and may have positive regulation on bcl-x L,then promote tumorgenesis.

AIM: To study the dynamic levels of tumor necrosis factor alpha (TNF-?), interleukin-6 (IL-6) and gamma interferon (IFN-?) produced by human dendritic cells infected with Dengue virus. METHODS: Monocytes isolated from healthy human peripheral blood were incubated in medium with GM-CSF and IL-4 for more than 7 days. DCs were then collected and identified by scanning electron microscope, immunohistochemistry and lymphocytes stimulatory ability. Human dendritic cells (DC) were infected with Dengue-2 virus (DV-2) in vitro, culture supernatants were collected in different time postinfection (6 h, 12 h, 24 h, 48 h and 72 h), DV antigen in human dendritic cells were demonstrated by an indirect immunofluorescent assay (IFA), production of TNF-?, IL-6 and IFN-? in the culture supernatants were evaluated by ELISA. RESULTS: After 7 days, typical dendritic cells could be obtained. Virus antigen were detected in infected DC by IFA. Dengue virus induces TNF-? and IL-6 secretion from DC and does not induce IFN secretion. CONCLUSION: Human dendritic cells are target of dengue virus infection. TNF-?, IL-6 production from DC are increased with DV infection. Dendritic cells may play an important role in DV pathogenicity and immunity.

Biologic scaffold materials derived from decellularized tissues and organs have been successfully used in tissue engineering and regeneration medicine.Decellularization methodology varies according to the differences of the origin,tissue density,composition,geometric and biologic properties of the tissue.Optimal decellularization method should be developed on the basis of complete cell content removal with the preservation of extracellular matrix (ECM) integrity and bioactivity.In this article,an overview of decellularization methods and their effect upon acellular bracket structure and composition are presented.

Cardiovascular disease has become the first cause of human death.Among the many risk factors in coronary heart disease,depression has been identified as an independent prognostic risk factors.In patients with coronary heart disease accompanied by severe depression,the onset of angina,quality of life deterioration and the mortality will increase by 3～5 times.However,the majority of antidepressant drugs have adverse effects on cardiovascular disease adverse drug reactions,making coronary heart disease patients with depression,did not receive antidepressant treatment due.So more researches to clarify the anti-depressant drugs,safety for cardiovascular disease are needed.

Aim To explore the molecular mechanism of interrelationship between thioridazine-induced learning and memory decline and the production of ?-amyloid (A?) in the rat brain. Methods Male Sprague-Dawley rats were injected intraperitoneally with thioridazine of 10 mg?kg-1?d-1 for 2 weeks in order to suppress cognition by inhibition of dopamine, acetylcholine and 5-hydroxytryptamine receptors. Morris water maze was used to measure spatial learning and memory performance. The A? content of brain was measured by radioimmunoassay. Immunohistochemistry was employed to determine ?-amyloid precursor protein (APP) level. The mRNA levels of APP,?-secretase and ?-secretase in brain were detected by RT-PCR. Results Thioridazine treatment to rats resulted in spatial learning and memory impairment shown by longer escape latency. Total A? was significantly increased by 1.3 times in thioridazine-treated rats. APP-immunoreactivities in cortex and hippocampus of thioridazine-treated rats were more pronounced than those of control rats. Levels of APP751 plus APP770 mRNA,?-secretase mRNA in brain increased nearly 2.5 and 2.6 folds respectively in thioridazine treated-rats, but no differences in mRNA levels of APP695 and ?-secretase were found between thioridazine-treated and control rats. Conclusion The thioridazine-induced cognitive decline is related to the increase of A? caused by elevation of APP751,APP770 and ?-secretase expression.

OBJECTIVE To find out the clinical characteristics of nosocomial infections with Stenotrophomonas maltophilia(SMA) and investigate the disinfectant resistant gene of qacE△1,improve the diagnosis and decrease of nosocomial infection cases.METHODS Toally 165 strains of SMA were clinically isolated from 2004 to 2007.The gene of qacE△1 was analyzed by polymerase chain reation(PCR) and homology of the strains was analyzed by the method of by pulsed field gel electrophoresis(PFGE) genotype.RESULTS Susceptible factors were old age,seriousness of underlying disease,prolonged hospitalization and invasive operation with infection of SMA.The lower respiratory tract infection was mostly common with SMA,rate of which was 87.9%.Antibiotic sensitive rate more than 80% against SMA was minocycline,trimethoprim-sulfamethoxazole and levofloxacin.The positive rate of gene qacE△1 was 13.3% in 60 strains tested.Two genotypes in SMA strains from respiratory ICU(RICU) were with the same clone.This result proved that clone transmission occurred in RICU.CONCLUSIONS SMA is an important nosocomial infection pathogen.With the multi-drug resistance,the therapy of infection with SMA is very hard in clinic.As result of gene of qacE△1 and the same clone transmission,clinicians should play an important role of surveillance of effect of disinfection.
