These ingredients includes epidermal growth factor, hepatocyte growth factor, dimethyl sulfoxide, phenobarbital sodium and all trans-retinoic acid. We isolate and culture primary 10-weeks-old human fetal hepatocytes, observe hepatocytes form and its function markers. Inoculate hepatocytes with HBV Dane particles to observe if HBV susceptibility of fetal hepatocytes can be induced in vitro. To detect HBV covalently closed circular DNA within hepatocytes, we improve the existent PCR method.

基于上述假设，我们设计了10种培养条件，在自行设计的无血清培养基中添加不同的细胞分化诱导物，包括表皮生长因子、肝细胞生长因子、二甲基亚砜、苯巴比妥钠、全反式维甲酸等，分离孕10周龄人胎肝细胞进行原代培养，观测肝细胞形态及功能指标变化，并定时给予HBV感染，观察能否在体外诱导胎肝细胞出现HBV易感性；为检测肝细胞内HBV共价闭合环状DNA(covalently closed circular DNA，cccDNA)，我们改进了现有的PCR检测法。

With propanal and malonate as reaction agents and piperidine as the catalyst, Knoevenagel reaction was used in the synthesis of flavor 2-pentenoic acid.

以丙醛和丙二酸为原料，哌啶为催化剂，采用Knoevenagel反应合成了食用香料2-戊烯酸反式构型，产率64.2%，其具有干酪味、淡烤香味。

However, there are still several safety concerns about the use of a DNA vaccine, which include the possibility of integration into the host genome, adverse immunopathology, and anti-DNA autoantibody induction.Attempting to solve some of these problems, eukaryotic expression plasmids pTL-8/ AMA-1 and pTL-8/ AMA-1 which express trans-activator or reverse trans-activator, respectively, and AMA-1 gene of Plasmodium falciparum were constructed by using tetracycline regulable system.

首先构建了恶性疟原虫顶第四军医大学硕士学位论文端膜抗原1(AMA一1)基因和反式活化因子基因的真核表达质粒pTL一8/灿认一l和PTL一8/灿认一1，并大量制备这两种质粒及表达转录抑制子的质粒pUHS6一1。

It was found that the allylide of sulfonium salt could react with aryl aldehydes to afford corresponding trans-epoxides in good yield with good trans/cis selectivity and excellent enantioselectivity.

根据反应条件对反应的影响并结合通过单晶测定的反式环氧化产物的绝对构型，我们提出了氢键起主导作用的手性诱导机制。
