According to the classical signal transduction pathway of estrogen, we use Luciferase reporter gene to screen phytoestrogen form Selaginella tamariscina, Pinus massoniana Lamb, Corallodiscus flabellate, Dryopteris sublaeta Ching et Hsu and Leonurus heterophyllus. In this study,the pβgal-Control vector, the pERE-TAL-luc vector, the pCNX2-hERα/pCNX2-hERβvector were transfected into HEK293 cell line. If the components in the herbs combine with the ER, then it could induce the expression of reporter gene controlled by ERE.

根据体内的雌激素信号转导途径，我们选用了以luc为报告基因、ERE为调控序列的重组报告基因载体pERE-TAL-luc，并将其与重组人ERα(humanERα，hERα)表达载体pCXN2-hERα和重组人ERβ(humanERβ，hERβ)表达载体pCXN2-hERβ共转染ER阴性细胞系，建立了靶向ERα或ERβ的细胞水平药物筛选模型，结合小鼠子宫增重实验，对卷柏、松针、益母草、石胆草及贯众等5种中药的植物雌激素作用进行了研究，以期为临床防治更年期综合症等提供准确、科学的实验基础。

The main contributions are as follows:(1) The decoherence suppression of N level Markovian systems is investigatedby the optimal control in the coherence vector representation. The N level Markoviansystem can be described by the master equation, and possesses a standard bilinear formin the coherence vector representation.

本论文利用密度矩阵相干向量表示研究了退相干效应的抑制和相应的纠缠控制问题，论文主要工作包括：(1)在密度矩阵相干向量表示下，利用最优控制研究N能级Markov系统的退相干抑制问题。N能级Markov系统可以用主方程模型描述，在相干向量表示下具有标准的双线性形式。

DsRNA technology was discovered recently, and many studies demonstrated that it could suppress genes more effectively than antisense technology. Inverted repeats of 800 bp TCS cDNA fragments sandwiching a 400 bp GUS gene fragment was inserted into the binary vector pBI121 and placed under the control of 35S promoter, forming a dsRNA expression vector.

DsRNA技术是近几年才刚刚发展起来的新技术，将上述DNA片段正向和反向插入到双元载体pBI121的35S启动子下游，两片段之间由约400 bp的GUS基因片段隔开，形成反向重复序列，由此构建成了表达TCS基因dsRNA的中间表达载体。
