目的：应用PCR方法对常染色体显性遗传性多囊肾病家系进行症前基因诊断。方法：用PCR扩增与PKD1位点连锁的的高度多态性的微小卫星体DNA（SM7，AC2.5，KG8，CW2）为遗传标记，对10个ADPKD家系的104个成员（包括28个患者）找出染色体上与疾病连锁的单体型，进行连锁分析。结果：对9个无临床症状，且B超检查呈阴性结果的儿童做出了症前基因诊断。结论：能够应用PCR方法对ADP－KD家系成员快速、准确地做出基因诊断

The populations of DH, TM and WC are the concentration places of wild Ginkgo biloba L.. Among these populations, there are a great numbers of seedlings, which have more strong renovative ability .Therefor, these are the best regions to protect the gentic diversity using combined with in situ and transferred and should establish conservation areas in these places.

基因调控网络模型试图从DNA微阵列等海量数据中推断基因之间的调控关系，从而揭示复杂的生命现象，虽远未完成，但从现有实验数据中重建基因调控网络的工作可以促进在分子和遗传水平上系统地剖析细胞的功能，是功能基因组学中的重要研究内容，也是当前生物信息学和系统生物学研究的最具挑战性的前沿课题之一。

The study of transcriptive regulatory networks intends to infer regulations between genes from microarray data, and reveals the complex life of cell. Also far from being completed, the ability to recreate transcriptive regulatory networks from available experimental data facilitates the systematic dissection of cell function. The research of transcriplive regulatory networks is an important topic in functional genomics, and one of the most challenging questions in the front of bioinformatics and system biology. Several typical mathematical models and their new research developments are discussed concisely.
