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。

The optimum conditions were reaction temperature 120°C, reaction time 20h, mole ratio of 5-chloromethyl-2-oxazolidinone and sodium phenolate 1:1. 3,5-Dimethylphenol and epichlorohydrin in sodium hydroxide were condensated to give l,2-epoxy-3-phenoxy propane, then the reation of l,2-epoxy-3-phenoxypropane and the carbamate afforded oxazolidinone in the yields of 69.0%~76.0%. The side reaction had been avoided effectively by the uses of the excessive epichlorohydrin and mixed catalysts.

用3，5-二甲基苯酚和环氧氯丙烷在氢氧化钠存在下缩合生成苯氧基环氧丙烷，然后和氨基甲酸酯反应生成噁唑烷酮，采用过量环氧氯丙烷和使用混合催化剂，有效的避免了副反应的发生，提高了噁唑烷酮的产率，产率69.0%～76.0%。

Hydroxylcarveol(3) and its ester derivatives were synthesized from α-pinene(1), and their structures had been identified by IR, MS, 1H NMR and 13C NMR analysis.

以α-蒎烯(1)为原料，合成了8-羟基别二氢葛缕醇(3)及其甲酸酯(4)、乙酸酯(5)和丙酸酯(6)，并用IR、MS、1H NMR及13C NMR分析对它们的结构进行了表征。
