Bronchial asthma is the most common chronic diseases in children.Asthma can not be fully explained by imbalance of Thl/Th2.With the research progress of CD4+ CD25+ Treg cell,it has been found that CD4+ CD25+ Treg cell related factors such as forkhead/winged helix transcription factor,heine oxygenase-1,transforming growth factor-β,cytotoxic T lymphocyte-associated antigen-4 are closely linked to asthmatic mechanisms.

支气管哮喘是一种儿童时期最常见的慢性疾病，单纯的Thl/Th2应答失衡并不能完全解释支气管哮喘的发生，伴随着CD4+CD25+调节性T细胞的研究进展，人们发现与CD4+CD25+Treg细胞相关的因素如叉头/翼状螺旋转录因子、血红蛋白加氧酶-1、转化生长因子β、细胞毒性T淋巴细胞相关抗原-4与支气管哮喘均有密切的联系。

Results Both GAMP derivatives and GAMP-protein conjugates showed GAMP antigen specificity. Compared with GAMP alone, the GAMP-protein conjugates induced high serum anti-GAMP IgG antibody level and strong bactericidal activity in vitro. The conjugate also induced immunological memory.

结果 多糖衍生物、多糖－蛋白质结合物均具有GAMP抗原特异性；结合物免疫小鼠可诱生较单独多糖更高水平的血清抗GAMP IgG抗体和更强的体外杀菌活性，并能产生免疫记忆。

Here, we report that SSEA-4, an early embryonic glycolipid antigen commonly used as a marker for undifferentiated pluripotent human embryonic stem cells and cleaage to blastocyst stage embryos, also identifies the adult mesenchymal stem cell population.

SSEA是在未分化的人胚胎干细胞表面早期表达，在胚泡期被剪切的一种糖脂类抗原，作者发现，SSEA也可以用来鉴定间充质干细胞。

The different fishes which are employed in the present studies are wild-type salmon, cultured salmon of freshwater and seawater, sea perch and fat greenling. The complete CT gene sequences of salmons are obtained by PCR amplification. The partial CT sequences of sea perch and fat greenling are obtained by in vitro cloning PCR method. Alignment of obtained CT sequences with other fish CT shows that CT appears to be well conserved among the same family. And the relative in taxonomy is far away, the similarity of different fish CTs is low. On the contrary, the closer the relative in taxonomy is, the higher the similarity of different fish CTs is. The sCT is expressed in pGEX-4T-X by recombinant form . We also succeed in the research of sCT expression alone by expression PCR. In addition, sCT antiserum is obtained using GST-sCT as antigen, and the high titer is tested by double immunodiffusion. In the rat bioassay, administration of 50 μg recombinant protein evoked significant hypocalcemia at 1 h after the data are analyzed by t-test.

本文用PCR方法克隆了野生鲑鱼、养殖鲑鱼的降钙素基因，并应用体外克隆PCR的方法首次克隆出鲈鱼、六线鱼降钙素的部分基因序列，通过对克隆的降钙素序列的比较研究，结果显示同一科的鱼降钙素序列保守性较高，同时，根据降钙素的部分氨基酸序列进行了降钙素相似性的比较研究，结果显示在分类学上，分类地位较远的鱼，其降钙素相似性较低，分类地位越接近的鱼，其降钙素相似性越高；我们利用谷胱甘肽S-转移酶(Glutathions S-transferase，GST)融合表达载体pGEX-4T-X对克隆的鲑鱼降钙素基因进行了融合表达研究，应用表达PCR的方法对降钙素基因的独立表达进行了初步的研究探索，并将纯化的融合蛋白作为抗原，获得了高效价的兔抗鲑鱼降钙素免疫血清；生物活性研究表明，大肠杆菌表达的融合蛋白具有显著的降血钙作用。
