Objective: The first aim of this study was to investigate bcr-abl associated T cell receptorVαand Vβgene repertoire by analyzing the restricted usage and clonal expansion of TCRVαand Vβsubfamily T cells from the normal individual peripheral blood induced bybcr-abl peptideso The second aim was to construct the idiotype TCR Vα-PIRES-TCR Vβeukaryotic vector and investigate its expression in vitro. The data will be expected toprovided the methods in development of the leukemia antigen specific cytotoxic Tlymphocyte modified by the specific TCR.

The Constipation group was subdivided into Slow-transit group and Normal transit group according to the TGITT to explore the value of anorectal manometry in different types of constipation.

对28例便秘儿童和43例正常儿童进行全胃肠传输时间、左半结肠传输时间、右半结肠传输时间和直肠乙状结肠传输时间测定和直肠肛管向量测压(包括肛管压力、向量容积和对称指数)。

Methods The immunofluorescency, Western blotting and RT-PCR were performed on mouse liver tissue obtained from 4 experimens pcDNA3.1(+-HBX and 1 normal control, 24 h after delivery the HBX gene eukaryon expression vector pcDNA3.1-HBX into mouse by the means of hydrodynamic injection.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
