人TCA-12-2/TCB-7.1真核双表达载体的构建与表达

目的：将T细胞抗原受体基因TCA-12-2和TCB-7.1共同构建在真核表达载体pDC315，用于哺乳动物细胞293转染研究。方法： 将分离得到的淋巴细胞总RNA反转录合成cDNA,以此为模板进行PCR扩增得到TCA-12-2基因；以实验室保存含TCB-7.1基因的质粒为模板，扩增得到TCB-7.1基因。随后酶切，连入载体pIRES2-AcGFP1，通过亚克隆连入载体pDC315，得到重组质粒pDC315-TCA-12-2-TCB-7.1。重组体质粒经酶切鉴定后，并对插入的TCA-12-2和TCB-7.1基因片段进行测序，将鉴定好的阳性重组质粒用脂质体介导转染293细胞，并通过RT-PCR和流式细胞仪检测TCA-12-2和TCB-7.1基因的表达情况。结果： TCA-12-2和TCB-7.1可以同时构建在载体pDC315上，RT-PCR和流式细胞仪检测发现TCA-12-2和TCB-7.1基因可以成功在293细胞上表达。结论：成功构建了含TCA-12-2和TCB-7.1基因的双表达载体。     

Interleukin-1 beta gene polymorphism related with allergic pathogenesis in Iris constitution

Iridological constitution has a strong familial aggregation and is implicated in heredity. The aetiology of inflammatory bowel disease is still unknown. However, from genetic epidemiological studies there is considerable evidence that genetic factors are associated with both Crohn's disease and ulcerative colitis. We investigated the relationships between Iridological constitution and interleukin 1 beta (IL-1β) gene polymorphism. IL-1β is a major proinflammatiry cytokine, and the polymorphisms of this gene have been shown to be of importance in a number of diseases. Especially, IL-1 has been suspected of involvement in allergic pathogenesis. Also, IL-1β genotype is one of the genetic markers of gastric cancer. Therefore, we classified 166 individuals according to Iris constitution, and determined IL-1β genotype. The frequencies of Iris constitutions as follows: neurogenic type, 41 (24.7%); abdominal connective tissue weakness type, 53 (31.9%); cardio-renal connective tissue weakness type, 50 (30.1%); the others type, 22 (13.3%). Especially, the frequency of abdominal connective tissue weakness type was higher in C/T genotype than in the remaining constitutions although the statistical power was very weak. Furthermore, we first attempted to explore possible involvement of the IL-1β polymorphism and the Iris constitution.     

上睑下垂美容手术的解剖学设计和效果分析

目的探讨不对称性上睑下垂美容手术的设计要点以及术后美容效果。方法通过对33例不对称性上睑下垂患者术前双眼各自不同特点的分析,提出设计要点,同时对术后的美容效果进行评价。结果本组病例中美容效果优者占87.9%,良以上者占94.0%。结论双眼对称是眼部美容手术成功的关键,只有按照患者各自的解剖学特点设计手术,才能取得良好的美容效果。

携带增强绿色荧光蛋白基因的Id2真核表达载体构建

目的：构建大鼠Id2基因真核荧光表达载体，为骨骼肌的组织工程研究提供有效的分子工具。方法：利用RT-PCR的方法扩增出Id2全长cDNA，利用T4 DNA连接酶将载体pGEM-T和Id2 cDNA进行连接，构建克隆载体，经限制性内切酶EcoR1酶切pGEM-Id2克隆载体和pEGF-C2真核表达载体，构建出重组真核表达载体pEGFP-C2-Id2，经酶切分析、PCR鉴定及DNA测序证实cDNA片段大小和序列的正确性；并通过细胞转染技术将Id2基因导入L6成肌细胞中。结果：经酶切分析和序列测定证实pEGFP-C2-Id2含大小正确的正向Id2 cDNA片段，获取了转染外源性Id2基因的L6细胞。结论：我们成功构建了同时携带有G418筛选位点和增强绿色荧光蛋白的Id2真核表达载体？     

抗单纯疱疹病毒CHA9-3D8单链抗体三维结构的计算机模建和分析

将１株分别来自单纯疱疹病毒ＭｃＡｂ（重链）和出血热病毒ＭｃＡｂ（轻链）的杂化单链抗体基因序列，在ＳＧＩ图形工作站上，利用同源蛋白结构预测的方法，建立起了其三维结构模型，以寻找轻、重链空间结构的相互关系，观察抗体的结构及表面静电性和疏水性的变化。结果表明，杂化链抗体的轻、重链位置得当，轻链参与组成了“疏水口袋”的形成，并有约五分之二的“袋口”部分由其围成，Ｌｉｎｋｅｒ链位置贴切，游离于轻、重链之外。轻、重链的３个超变区围绕于疏水口袋附近。这一研究为进一步分析轻、重链在抗体功能中的作用，以及改造抗体并提高抗体活性等方面提供了一种途径。     

Medical informatics education by medical professors within their discipline

A system for medical informatics education for medical students has been developed in the medical school. This paper describes the concept underlying the development of this system and its progressive outcomes over 8 years. In order to stimulate students to acquire computer-related knowledge and skills, this subject has been integrated into the course works of various medical subjects such as physiology. In addition, acquired knowledge and skills are evaluated within each subject by the production of reports for example, using computers. This provides a concrete example for students of the relevance of the information sciences to the solving of medical problems. A well equipped computer facility for the study of medicine also plays a significant role in inspiring student incentive. A computer room equipped with Macintosh computers was opened adjacent to the main medical library and is used in the same manner as the library, with books replaced by computers. In addition, all new students acquire their own Macintosh PowerBook. These various initiations have facilitated concept that the computer may be applied to medical problem solving at any time or place and may become as commonplace as a pen in daily medical practice.
