Results (1) The forward and reverse subtracted cDNA libraries of different metastastic potential large cell lung cancer cell lines were successfully constructed;(2) With blue-white colony and dot blot, 307 positive clones in the forward subtracted library and 78 positive clones in the reverse subtracted library were obtained;(3) 55 clones were successfully sequenced in the forward subtracted library. Homolog analysis confirmed 23 differential expression segments, which were similar to the human genes already known, including NME2, NPM1, MT 2A, HSPE1, TAFIA, EPRS, PX19 and EIF3S9 et al;(4) 31 clones were successfully sequenced in the reverse subtracted library. Homolog analysis confirmed 16 differentially expressed segments. 15 of them were similar to the human genes already known, including ANXA2, TUBB, PKN2, GNAS, EEF1A1, SSR2 and RPLPO et al. Only one segment had partial homology to known human genes. This segment was supposed to be the new EST segments which might not have been cloned.

结果(1)成功构建人大细胞肺癌高低转移株差异表达基因正向消减cDNA文库和反向消减cDNA文库；(2)经蓝白菌落筛选和斑点杂交，正向消减文库获得307个阳性克隆，反向消减文库获得78个阳性克隆；(3)正向消减文库挑选55个克隆成功测序，经同源性分析最终确定差异表达基因片段23个与已知人类全长基因具有很高相似性(95％～100％)，这些基因包括NME2、NPM1、MT2A、HSPE1、TAFlA、EPRS、PX19和EIF3S9等；(4)反向消减文库挑选31个克隆成功测序，经同源性检索和比对最终确定差异表达基因片段16个，其中15个与人类全长基因具有很高相似性(95％～100％)，包括ANXA2、TUBB、PKN2、GNAS、EEF1A1、SSR2和RPLPO等基因。1个片段和己知人类基因仅有部分相似性，表明它可能是未被克隆的人类基因EST片段。

In this study, the brill pos tagger and the claws7 pos tagger have been used to assign pos tags to the same set of transcribed spoken data produced by a high-proficiency group and a low-proficiency group of efl learners. the pos tags have then been manually examined, and the success rates of the taggerscompared.

本研究采用brill和claws7两种词性赋码器分别为高低分组学习者口语语料进行自动赋码，统计赋码准确率，并比较两种赋码器对学习者口语特征的处理能力，目的在于考察基于规则的词性赋码器和基于概率的词性赋码器对学习者口语语料进行自动词性赋码的适用度，以期为中介语口语的句法特点研究提供依据。
