乙型肝炎

The overall incidences of adverse events of two groups were similar.

抗病毒治疗是乙型肝炎的主要治疗手段。

Objective To study the effects of 20/21 bp partial deletion mutation (from nt 1 748 or nt 1 747 to nt 1 767) in the core promoter region of hepatitis B virus genome complicated by precore stop condon mutation at nt 1 896 on the expression of the viral antigens.

目的为研究乙型肝炎病毒核心启动子20/21bp部分缺失(nt1748/1747至nt1767)及同时存在的A1896点变异对病毒抗原表达的影响。方法利用前期构建的HBV全基因的重组载体转染HepG2细胞后，对病毒抗原进行ELISA检测及Western-blotting分析。

The research team analysed blood and sweat samples from 70 male Olympic wrestlers for evidence of hepatitis B infection.

研究小组分析了鲜血和汗水样本，由70男奥运会摔跤的证据乙型肝炎病毒感染引起的。

Woodchucks . The HBV genome has four genes: pol, env, pre-core and X that respectively encode the viral DNA-polymerase, envelope protein, pre-core protein (which is processed to viral capsid) and protein X. The function of protein X is not clear but it may be involved in the activation of host cell genes and the development of cancer.

乙型肝炎病毒基因组有四个基因：波兰，环境，前核心和X ，分别编码病毒DNA聚合酶，包膜蛋白，前核心蛋白和蛋白质十大功能蛋白X是尚不清楚，但它可能参与激活宿主细胞的基因和癌的发展。

Replicative intermediates of hepatitis B virus in HepG2 cells that produce infectious virions .

Transmission of HIV by needle-stick injury, estimated at about 1/300 incidents, is much less frequent than transmission of hepatitis B, presumably because of the relatively lower number of HIV virions in the blood of most infected patients.

由针刺损伤导致的HIV传播发生率估计为1/300，远低于乙型肝炎，这可能是由于大多数感染者血液中的HIV病毒数量相对较少的原故。

Genome replication, virion secretion, and e antigen expression of naturally occurring hepatitis B virus core promoter mutants［J］.

Detecting each marker and cmparison the location of sequential tissuesection could determine the area loceation relationship of the markers, but it is difficulte to determine their correlation intra-cells exactly. No report of detecting virus genome and antigenes on a one section with triple staning techniques exists in the lit erature. in this report. by combining immunohistochemistry and in situ hybridization (with dioxigenin labelled HBV DNA probe), a triple staining technigce was established. With this technic, on one formalin-fixed and paraffin embeded section, HBV DNA, HBsAg and HBcAg were determinated one after the other.

各个细胞内病毒的复制和表达水平以及与肝细胞病变的关系，是乙型肝炎发病机理研究的一个重要方面：目前常用的在系列切片上对各标志物分别检测，比较观察的方法，一般只能大致了解各待检物在某一区域的定位关系，很难准确地了解它们在同一细胞内的关系：国内外尚未见有在同一张切片上三重标记染色检测病毒核酸及其多种抗原的报道：本文结合免疫组织化学ABC法及地高辛配基标记HBV DNA探针原位杂交，建立三重标记染色技术：在一张福尔马林固定石蜡包埋肝组织切片上先后检测，同时显示HBV DNA、HBcAg和HBsAg。

Observed the cleavage activity of three single and connected ribozymes on target RNA.

目的： 探讨单一及多位点核酶对乙型肝炎病毒靶RNA的切割作用。

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。
