论中国近代文学的本位性

学习与探索 2004年第6期 136-140页

作者：高玉梅新林浙江师范大学浙江金华321004

中国近代文学是一种过渡性的文学类型,它具有自己的本位性,表现为变动不居、价值多元、内在的紧张与冲突、探索与创造等特征。近代翻译文学是中国近代的本位性文学。确立中国近代文学的本位观对中国文学通史具有关键性意义。

World Journal of Gastroenterology 2003年第12期9卷 2732-2736页

作者： Jian Zhuge Ye Luo Ying-Nian Yu Department of Pathophysiology,School of Medicine,zhejiang university,Hangzhou 310031,zhejiang Province,{2. Department of Pathophysiology School of Medicine Zhejiang University Hangzhou 310031 Zhejiang Province China.

AIM: Human cytochrome P-450 2.1 (CYP2.1) takes part in the biotransformation of ethanol, acetone, many smallmolecule substrates and volatile anesthetics. CYP2.1 is involved in chemical activation of many carcinogens,procarcinogens, and toxicants. To assess the metabolic and toxicological characteristics of CYP2.1, we cloned CYP2.1 cDNA and established a HepG2.cell line stably expressing recombinant CYP ***: Human CYP2.1 cDNA was amplified with reverse transcription-polymerase chain reaction (RT-PCR)from total RNAs extracted from human liver and cloned into pGEM-T vector. The cDNA segment was identified by DNA sequencing and subcloned into a mammalian expression vector pREP9. A transgenic cell line was established by transfecting the recombinant plasmid of pREP9-CYP2.1 to HepG2.cells. The expression of CYP2.1 mRNA was validated by RT-PCR. The enzyme activity of CYP2.1 catalyzing oxidation of 4-nitrophenol in postmitochondrial supernate (S9) fraction of the cells was determined by spectrophotometry. The metabolic activation of HepG2.CYP2.1 cells was assayed by N-nitrosodiethylamine (NDEA)cytotoxicity and micronucleus ***: The cloned CYP2.1 cDNA segment was identical to that reported by Umeno et al(GenBank access No.J02.43). HepG2.CYP2.1 cells expressed CYP2.1 mRNA and had 4-nitrophenol hydroxylase activity (0.162.***-1 S9 protein), which were undetectable in parent HepG2.cells. HepG2.CYP2.1 cells increased the cytotoxicity and micronucleus rate of NDEA in comparison with those of HepG2.***: The cDNA of human CYP2.1 can be successfully cloned, and a cell line, HepG2.CYP2.1, which can efficiently express mRNA and has CYP2.1 activity, is established. The cell line is useful for testing the cytotoxicity,mutagenicity and metabolism of xenobiotics, which may possibly be activated or metabolized by CYP2.1.

特征子集选择问题一直是人工智能领域研究的重要内容,特别是近几年来,特征子集选择的算法研究已经成为机器学习和数据挖掘等领域的一个研究热点。该文在扩张矩阵的基础上提出了类扩张矩阵的概念,并将加权的期望信息和不一致错误率函数应用于特征子集的选择,实现了具有噪音处理功能的渐进式特征子集选择算法———IFSS_EM,实际领域的实验结果表明:IFSS_EM算法具有运行效率高、选择特征较具有代表性的优点,从而使其能够较好地应用于实际领域。

2.世纪80年代中后期以来,中国的女性小说创作走向了历史性的繁荣时期,这不仅表现在价值观念上,也在艺术表达方式上向传统的文学理论、文学史提出挑战。不少女性小说家执迷于以游戏方式操练小说,从而颠覆了既往男性话语所指定的女性小说文体样态,为女性小说的多元化发展表明了另一种向度。透过"游戏"的面纱,我们可以看到这类小说丰富的诗性内涵和神圣的目的意义。
