猪繁殖与呼吸综合征(PRRS)是危害我国生猪业的重要疫病之一,其病原是猪繁殖与呼吸综合征病毒(PRRSV),是一种免疫抑制性病毒。干扰素(IFN)是一类具有免疫调节功能和抗病毒作用的细胞因子。IFN-α除更直接的抗病毒作用外,还可以调节宿主的先天性和适应性免疫。论文构建表达IFN-α的重组PRRSV,分析重组病毒的生物学特性以及IFN-α的生物学活性。通过反向遗传操作方法将IFN-α插入到PRRSV ORF1b和ORF2a之间,重组质粒转染细胞后可以拯救出重组病毒(rGXAM-P-IFN-α)。插入到PRRSV基因组中的IFN-α可遗传稳定9代。重组病毒生长特性分析可发现rGXAM-P-IFN-α复制能力显著低于亲本病毒。rGXAM-P-IFN-α感染猪肺泡巨噬细胞(PAM)可显著上调抗病毒基因(PKR,ISG15和ISG54)mRNA表达水平,为进一步研发新型PRRSV疫苗提供参考。

Increasing the rotating speed is considered as an efficient approach to upgrade the power-to-weight ratio in an axial piston pump,but penalized by more leakage and more severe wear resulting from the adverse cylinder block *** studies mainly focused on the bearing characteristic of the valve plate/cylinder block pair,but the spline coupling also plays a key role in the undesired cylinder block tilt,which has been little studied.A theoretical model for the rotating assembly is presented to investigate the effect of the spline coupling length on the cylinder block tilt and the performance of the valve plate/cylinder block pair.A typical high-speed axial piston pump with the displacement of 5.2 mL/r at 10000 r/min was studied by simulation and *** shows that the optimal spline coupling length is one value increased by 2 mm from the original,bringing a remarkable leakage reduction under the high-speed condition by decreasing the cylinder block tilting *** experiment result matches well with the *** influences of the spline coupling on the cylinder block tilt and the leakage were demonstrated.
