Conclusion Helper T cell(TH) Ⅰ response is induced in mice by mixed recombinant of BCG-Em Ⅱ/3 and BCG-Em14-3-3 vaccine on early immunization.

Objective To analyze the Brucellosis incidence and to predict the trends of the disease in Shanxi province and the national in recent years,which could provide the reference for surveillance,prevention and control of the disease.Methods Brucellosis data which was reported monthly during January 2006 and December 2010 in Shanxi province and the data released by Chinese Center for Disease Control and Prevention during January 2005 and December 2010 were collected.Several indexes,such as the annual increasing number,the development rate,growth rate and other indicators were applied to compare Shanxi province with the national Brucellosis epidemic in recent years.What's more,the seasonal autoregressive integrated moving average model (ARIMA) was fitted respectively with the data of Brucellosis incident number reported monthly,so as to predict the prevalence status in the coming two years by verifying the fitting effect.Results Brucellosis prevalence of Shanxi province reached the peak in 2008,and the incidence number was 5397,which was 900 more than 2007.From the onset of decline after 2008,the prevalence decreased by 17.67％ (906/5128) in 2010.However,national incidence of Brucellosis kept increasing before 2009 and the prevalence increased rapidly from 2007 to 2008,and the growth rate reached 39.16％ (8442/21 560).Although the number of Brucellosis fell by 2041 cases in 2010 than in 2009,the rate of decline was only 5.14％(2041/37 734).The fastigium of Brucellosis was from May to July yearly whether Shanxi province or the country.The ARIMA models of Shanxi province and the nation were ARIMA [(1,0,1)(1,1,0)12] and ARIMA[(1,0,1)(0,1,1)12],respectively,according to the incidence numbers reported monthly.The fitting effect of models showed that the predicted values of the two models were both consistent with the actual situation and all predicted values fell within the 95％ confidence limits,which depicted that they both fitted well.The predicted values depict that the incidence of Brucellosis overall trend was basically stable in Shanxi province,while the numbers in the nation would increase in a small extent in 2011 and 2012.The fastigium of Brucellosis was still from May to July yearly.Conclusions Brucellosis control measures are effective in Shanxi province,incidence of Brucellosis declining.The ARIMA model could predict the number of Brucellosis well,which can provide a valuable reference for the predication and evaluation of Brucellosis epidemic in the future.

Objective To investigate the changes of cytokines of splenocytes in mice immunized with recombinant BCG-Em Ⅱ/3 vaccine of Echinococcus multilocularis(Em)and consequently challenged with Em protoscoleces.Methods Balb/c mice were subcutaneously or intranasally vaccinated and challenged with Em were separated and cultured with EmAg,ConA or PHA,respectively.The supematants were gathered to measure the levels of IL-2,IFN-γ,TNF-α.and IL-4 by ELISA Kits.Results The levels of IL-2,IFN-γ,TNF-α and IL-4 in the subcutaneous group were(34.6±2.7),(34.5±2.8),(265.0 ±0.0)and(9.8±2.6)ng/L respeetively:those in the intranasal group were(32.5±2.2),(33.6±2.7),(130.0±0.0)and(10.4±27)ng/L respectively;those in the control were(25.0±1.9),(30.0±0.0),(10.0±0.0)and(12.5±2.7)ng/L,respectively:there were statistical differences between the immunized groups and control group(P＜0.01 or＜0.05);The level of TNF-α in the subcutaneous group was higher than that in the intranasal group.Conclusion Th1 response has been induced in mice vaccinated with rBCG-Em Ⅱ/3 vaccine and challenged with Em protoscoleces.

Objective To compare the effects of different resuscitation pressure on lung function of rats with uncontrolled hemorrhagic shock.Methods Uncontrolled hemorrhagic shock model of rats was built.Sixty Sprague-Dawley rats were randomly sent into six groups: NC group (the control group),NF group (shock but non-resuscitation),NS40,NS60 group (limited fluid resuscitation),NS80,NS100 group (large-volume fluid resuscitation).When the mean arterial pressure (MAP) reached between 35 mm Hg to 40 mm Hg (1 mm Hg=0.133kPa) resuscitation was begun,normal saline infusion was used to maintain the following desired endpoints.After the fluid resuscitation for one hour,rats of each fluid resuscitation group were given haemostasis and all-out fluid resuscitation,including blood infusion,to maintain the rats' MAP at 90 mm Hg.Results Findings showed that the blood loss in limited fluid resuscitation groups was significantly lower than that in large-volume fluid resuscitation groups at the situation of uncontrolled hemorrhagic shock,damage to lung tissue pathology and acidosis were significantly lower than those in large-volume fluid resuscitation groups.Nine rats in NS60 group survived 72 hours.Three rats in NS40 group survived 72 hours.No rat in NF group as well as in both NS80 and NS100 groups survived 72 hours.Conclusions Uncontrolled hem-orrhagic shock in trauma and different pressure of fluid resuscitation can cause lung injury to varying de-grees.Limited fluid resuscitation provide significant protective effects against such injuries.

The genetic analysis of herpesviruses has been a constant challenge, due to the large, complex genomes of herpesviruses and mutagenesis of viral genes by conventional recombination methods in cell culture. Recently, a completely new approach for full-length infectious clones of herpesviruses based on bacterial artificial chromosomes (BACs) has been developed. This technique allows the maintenance, propagation and genetic modification of the viral genome as a BAC plasmid in E.coli, thus making the procedures fast, safe and effective in prokaryotic cells. This technique also makes it possible for the reconstitution of viral progeny or mutants by transfection of the BAC plasmid into eukaryotic cells, thereby facilitating the analysis of viral gene functions in the context of genome. In this presentation, Epstein-Barr virus was used as an example to describe the principle, establishment of the technique and mutation introduction into the BAC plasmid, and to discuss the perspective in the use of BAC-cloned herpesviruses.

Objective To investigate the effects of deletion of adenosine A2A receptors on peripheral leukocytes on cerebral white matter lesions induced by chronic cerebral hypoperfusion.Methods Twenty-four wild type(WT) male mice were given a ? irradiation of 12.5Gy,followed by receiving bone marrow cells tail vein from female A2A receptor knocked out(KO) mice via tail vein,were assigned as KO→WT group,while those received bone marrow cells from WT female mice were assigned as WT→WT group(n=20).The efficiency of reconstitution of bone marrow cells in recipient mice was assessed 7 weeks after transplantation by PCR and immunofluorescent technique.Then,the recipient mice were subjected to bilateral common carotid artery stenosis with internal diameter of 0.18mm by external banding using microcoils at 8 weeks after transplantation.On 7d,14d and 30d after the surgery,corpus callosum,fiber bundles of Caudoputamen and optic tract were harvested from the cerebral white matter,and stained with Kluver-Barrera staining for observing the changes in nerve fibers,and with GFAP and CD11b immunohistochemistry staining for observing the proliferation of microglia and astrocytes.Results At 7 weeks after successful transplantation,the genotype of sex chromosome in peripheral leukocytes of the male recipient mice was changed into female pattern.The expression rate of A2A receptor was 9.73%?2.05% in KO→WT group and 93.82%?11.24% in WT→WT group,with significant difference between the two groups(P

Objective To observe behavioral characteristics and pathologic changes of chronic cerebral hypoperfusion in mice. MethodsTotally 62 adult C57BL/6 mice were subjected to either sham-operation (n=31) or bilateral common carotid artery stenosis using external microcoils with an inner diameter of 0.18 mm(n=31). At 30 d after the stenosis, the animals of the 2 groups (8 mice for each group) underwent behavioral test of 8-arm radial maze. In 7, 14 and 30 d, the rest mice were sacrificed for their brain tissue samples which were examined with Kluver-Barrera staining and immunohistochemical assay for markers of microglia and astroglia, glial fibrillary acidic protein (GFAP) and CD11b. In 14 d after the model establishment, Evans blue dye extravasation test was performed for the blood-brain barrier function. ResultsThe model group made significantly more errors than sham-operated group in 8-arm radial maze test at 30 d after the surgery. White matter lesions occurred and the proliferation of activated microglia and astroglia were observed in white matter in model mice after 14 and 30 d bilateral common carotid artery stenosis. The disruption of blood-brain barrier function of model mice was indicated in the evans blue extravasation test at 14 d after bilateral common carotid artery stenosis. ConclusionCognitive impairment, white matter lesions and glial activation are successfully induced after bilateral common carotid artery stenosis in mice model of chronic cerebral hypoperfusion.
