Results The activation of NF-κB, proliferation response, and expression of IL-4 and I L-5 mRNA and protein in T lymphocytes stimulated by PMA were significantly hig her than those of their blank control (P.01), while those indexes of T l ymphocytes stimulated by PMA and PDTC simultaneously were significantly lower th an those stimulated by PMA alone (P.01). The apoptotic index of T lympho cytes stimulated with PMA were significantly lower than that of their blank cont rol (P.01), and the apoptotic index of asthmatic guinea pig T lymphocytes stimulated with PMA and PDTC simultaneously were significantly higher than that stimulated by PMA alone (P.01). The significant positive correlations w ere found between the activation of NF-κB and the proliferation (r=0.64, P.001), and the expression of IL-4 and IL-5 mRNA and protein of T lymph ocytes, respectively (r=0.55-0.68, P.001). There was also signific ant negative correlation between the activation of NF-κB and apoptosis of T l ymphocytes (r=0.62, P.001). Conclusions NF-κB may participate in the signal conduction of PKC regulated proliferation, apoptosis and expression of IL-4 and IL-5 of T lymphocytes in asthma.

结果加入PMA培养的哮喘组T淋巴细胞NF-κB的活化、细胞增殖反应、IL-4和IL-5的mRNA和蛋白质的表达均显著高于其空白对照(P.01)，而同时加入PMA和PDTC培养的哮喘组T 淋巴细胞以上指标均显著低于只加入PMA培养的哮喘组T淋巴细胞(P.01)；加入PMA 培养的哮喘组T淋巴细胞的凋亡指数显著低于其空白对照(P.01)，而同时加入PMA 和PDTC培养的哮喘组T淋巴细胞凋亡指数显著高于只加入PMA培养的哮喘组T淋巴细胞(P 。01)。T淋巴细胞NF-κB的活化与增殖反应呈显著正相关(r=0.64，P.00 1)，与IL-4和IL-5的mRNA和蛋白质的表达也均呈显著正相关(r=0.55-0.68，P 。001)，而与凋亡指数呈显著负相关(r=-0.62，P.001)。

The simulation results shows that when the hydroforming for real axle housing needs two bulge processes and the specific value of the two bulge ratio is about 1, the result is the best one; To obtain an appropriate route of loading force need adjust internal pressure and axial compression force for many times and according to the failure, the size of the two forces which has been mentioned can be rapidly and rationally adjusted; Because of good greasing conditions influencing largely, reducing the friction between tube blank and die inside surface as well as possibly not only makes more materials flow into the bulge area but effectively diminishes the axial compression force; The good or bad characteristics of tube blank material is also one of the decisive factors and when material is selected, we first consider its' formability.

模拟结果表明，当后桥壳需要两次进行胀形，两次胀形比比值约等于1时，胀形结果最好；合适的加载路径要经过多次调试，能根据胀形缺陷对内压力和轴向力的大小进行迅速地合理调整；良好的润滑环境对后桥壳液压胀形的影响巨大，要尽量减小管坯与模腔内壁的摩擦力，不但使更多的材料流入胀形区，而且能有效的降低轴向力的大小；管坯材料性能的好坏也是影响胀形的决定性因素，选材时首先要考虑材料的成形性。

trailer&这词来源于预告片最先是在一部影片的片尾播出，这种播出方式没有持续多久，因为观众在影片结束后即要离开影院，尽管如此，&trailer这个名词延续了下来。

But utility time of this technology is not long at home, in addition, the majority of equipment is two-hand at home, and the craft technology was not introduced with it, so the people's understanding is limited to cast the copper alloy blank using the horizontal continuous casting method, the basic data lacks extremely, the copper alloy materials blank's quality is unstable, more than all, the research to the key component Graphite Crystallizer is insufficient, it affected the application of horizontal continuous casting in a certain.

但这一技术由于国内使用的时间不长，加之国内引进的大多数是二手设备，对工艺技术没有进行引进，因而人们对铜合金带坯的水平连铸生产方法认识有限，基础资料十分缺乏，生产的坯料质量不稳定，特别是对关键部件石墨结晶器研究不够深入，在一定程度上影响了水平连铸方法在铜合金带坯生产中的应用。
