The expression level of metabolitic enzyme (CYP1A1, CYP1B1) and its correlation with cell differentiation /apoptosis were studied as well. The influence of resveratrol in cell cycle was determined with FCM. Results 1 Resveratrol not only suppresses the growth of medulloblastoma cells in a dose and time related fashion but also induces cell differentiation and apoptosis. Resveratrol promotes differention of UW228-1,-2 cells to forward glia, UW228-3 and Med-3 cells to neuron. A treatment of resveratrol in the concentration of 100μM for 48hrs comit most of cells die of apoptosis. 2 Among the four cell lines Fas and Caspase-3 were constantly expessed, whereas FasL was absent irrespective to the drug treatment. 3 ICC, RT-PCR, Western-blot hybridization and EROD enzymatic activity assay demonstrated that expression of CYP1A1 is different after treatment with resveratrol in four cell lines, up-regulated in three UW228 cell lines in a dose dependent manner but down-regulated in Med-3 cells. Suppressive effect of resveratrol on CYP1B1 expression is the same among four medulloblatoma cell lines. 4 Cell cycle distribution of UW228-3 was greatly changed after treatment.

结果：1、白藜芦醇以时间和剂量依赖性方式抑制髓母细胞瘤细胞生长，同时促进细胞的分化和凋亡：白藜芦醇促使UW228-1、-2靶细胞向神经胶质细胞方向成熟分化，UW228-3、Med-3细胞向神经元细胞方向成熟分化，以100μM作用48小时效果显著；2、四个细胞系均有Fas和Caspase-3表达，但无Fas-L基因表达和蛋白活性产生，因此难以形成Fas相关性死亡通路；3、白藜芦醇处理前后CYP1A1基因的表达在各细胞系略有不同：UW228-1，-2，-3三个细胞系白藜芦醇以剂量相关性方式上调CYP1A1的表达，而Med-3细胞系，白藜芦醇却抑制CYP1A1的表达；四个细胞系在白藜芦醇处理后CYP1B1的表达均受到抑制；4、UW228-3细胞系经白藜芦醇作用后细胞周期有较大改变，表现在G0/G1期在整个细胞周期中所占的比例增加，而其它时期则相应减少。

The author considers that two problems are worth reflecting and studying:One is the regulating range;the other is that when legislators regulated the rights of software copyrighter that regulated in the eighth item of Computer Software Protection Byelaw,they did not consider the characteristics of computer software itself and concerning to protection period, it did not solved interest balance in copyrights protection of software.

二是我国《计算机软件保护条例》第八条规定了软件著作权人所享有的一系列权利，大都是因袭了著作权法对著作权保护的规定，并没有考虑到计算机软件本身的特性。另外从保护周期等方面考虑，软件著作权保护中并没有解决利益平衡问题。

Results: 63 genes were up-regulated and 64 genes were down-regulated in the 127 differential expression genes.

Results: miR27a was identified as the most stable reference gene by geNorm and Normfinder software. Among the 52 microRNAs detected by real time PCR array, miR-33 and miR-19a were significantly down-regulated, whereas miR-130 were significantly up-regulated in the hippocampus of Ts65 Dn mice as compared with the euploid control mice. The expression of miR-802, which was the trisomy chromosome 16 derived microRNAs, was very low in hippocampus with no difference between the two groups.

结果：geNorm和Normfinder两种方法均选定miR-27a为最稳定的内参照基因，共检测了52种microRNAs，其中miR-33和miR-19a在Ts65Dn小鼠海马组织中表达显著下调，miR-130在Ts65Dn小鼠海马组织中表达显著上调，小鼠16号染色体三体区段包含的miR-802在Ts65Dn小鼠和对照二倍体小鼠海马组织中表达量均低，差异没有统计学意义。

Up-regulated proteins under salt stress include an ABC transporter permease, glycerol-3-phosphate permease, pyrimidine nucleotide transporter, formate dehydrogenase, and down-regulated proteins include succinate dehydrogenase iron-sulfur subunit, flavoprotein subunit, cytochrome b-556 subunit, and a hypothetical membrane protein similar to charperone DnaJ. Some of these changes were further verified by enzyme activity assay.
