Next the discussion in this study, about an ellipse with an angle of attack and two circular cylinders with different diameters in the flow, the aim of this study is investigated for the ability of the present numerical method by solving the suppression of the vortex shedding flow behind the two-cylinder system which was kind of difficult to reach by a Cartesian grid method. In this study, the suppression of the vortex shedding flow is tested to solve a uniform flow past through two different diameter cylindrical in the flow field with Fractional Step Method and Immersed Boundary Method.The numerical method which we investigated is showed that the results of the problem is appropriable in other literatures.

Three major clusters of numt sequences ( cyt b numt、 ATP8+ATP6 numt and ND4+ tRNA-His+ tRNA-Ser numt) were particularity amplified and sequenced from 10 species within Galliformes and A.galericalata. Comparison numts sequences with homologous mitochondrial partial genes get the different evolutionary characteristics and evolutionary speed compared to mtDNA, then examine the age of insertion of numts using the sequence divergence of numt from the mtDNA. Finally, joined Coturnix japonica、 Coturnix chinensis、 Lophura leucomelana、 Lophura swinhoii and A.albifrons mitochondrial sequences in GenBank, we study the importance function to phylogenetic research of mitochondrial genes and homologous numts.The evolutionary rate of Numts is lower than their authentic sequences of mtDNA, cyt b and ND4 gene evolve faster than homologous numts 2.5 times; ATP8+ATP6 gene evolve faster than numts 18.9 times in Galliformes. Numts show less codon position bias and transition bias under not phylogenetic pressure.

PART 2:The molecular mechanisms of Nontypeable Haemophilus influenzae induced inflammatory response in respiratory epithelial cells Objective:Nontypeable Haemophilus influenzaewas traditionally considered as an extracellular pathogen in respiratory infections.In this study,we established a model of infected cells to confirm NTHI was also a facultatively intracellular pathogen.Mitogen activated protein kinasesare the important signal transduction pathway in mediating inflammatory response induced by NTHI in respiratory epithelium.In this study,we elucidate the impact of NTHI,and its SCF and EP on the expression of MAPK and subsequent proinflammatory mediators.

The N gene ORF was then subcloned into pET-30a vector and the recombinant plasmid was transformed into E.coli BL21 (DE3) and induced with IPTG. The protein expression was determined by SDS-PAGE. The expressed protein had a molecular weight of 54.4 Ku that existed as inclusion body. Thin-layer scanning showed that the expression product accounted for 30.5% of the total bacterial proteins. The recombinant protein possessed native biological activity and could react with anti-PEDV hyperimmune serum in Western blot.
