盐地碱蓬甲型和乙型肝炎联合疫苗

We amied the BCP sequence and the preS2 gene sequence of HBV separately as the target region, according to HBV DNA sequence of Chinese strain, synthesized the set of specific primers, amplified the sequence by PCR method from the serum of patients with CHI, verified by restriction analysis, subcloned into pGEM Teasy vectors, employed polyacrylamide gel electrophoresis to display the deletion mutation and selected the clones with differential length to be sequenced.

本研究应用PCR技术及其他分子生物学技术，分别以HBV转录调控序列BCP以及表面蛋白编码序列pre S2为靶基因，以中国株HBV基因序列为依据，设计特异性多聚酶链反应引物，分别自43例、51例慢性HBV感染患者血清中扩增出目的片段，构建质粒Teasy-BCP和Teasy-pre S2，酶切鉴定后，采用聚丙烯酰胺凝胶电泳技术展示缺失突变，再经DNA测序以了解在慢性乙型肝炎患者体内的病毒变异情况。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
