In Part 1 of our research, BGSCs were sorted through immunomagnetic beads marking by CD133 and cultured in vitro, and character as a stem cell was identified by stem cell markers (CD133 and Nestin) and differentiated cell markers [ microtubule-associated protein 2(MAP2), glial acidic fibrillary protein and myelin basic protein] , ultrastructure observing with electron microscopeand engrafting to severe combined immunodeficiency mice for tumorigenesis test. The results were as following: Only a small subset of CD133+ glioma cells in glioma cell lines and fresh specimens from various pathologic grade could express stem cell markers CD133 and Nestin, view ultrastructure of a stem cell and be capacity of serial passage in culture. These CD133+ cells possese a marked capacity for multipotent differentiation and could differentiate into tumor cells expressing MAP2,β-TubulinⅢ, GFAP and MBP; When engrafted into SCID mice, they can generate and form tumors that phenotypically resembl the tumor from the patient.
在本课题中,在第一部分实验中采用以CD133为标志的免疫磁珠法从人脑胶质瘤组织和细胞株中分离脑胶质瘤干细胞并进行体外培养,通过免疫荧光技术检测干细胞标志物CD133、Nestin,诱导分化后检查分化细胞标志物MAP2、GFAP、MBP以及电镜超微结构观察和移植SCID鼠致瘤实验,对其干细胞特性加以鉴定,得到如下结果:不同病理分级的新鲜胶质瘤标本和胶质瘤细胞株中存在一小部分CD133+的胶质瘤细胞,能表达干细胞的标志物CD133和Nestin,符合干细胞的超微结构特点,体外培养能连续传代;具有多向分化潜能:诱导分化后能产生MAP2、β-TubulinⅢ、GFAP、MBP染色阳性的细胞;移植SCID鼠后能形成与亲本肿瘤表型一致的移植瘤。

Using this model three competence-deficient pneumococci, which was identified by PCR and transformation experiment, were constructed. It is found different strain has different bacterial optimal density for being induced into competence. The optimal density for strains 1, 2 and 22 was 0.1, 0.08and 0.07 respectively. The optimal condition for transformation is c plus y culture at pH8.0. In c plus y culture at pH6.8, which restrained pneumococci forming transformation naturally, pneumococci could be induced to form transformation by CSP.It is concluded that we could induce different S.pneumoniae by CSP into competence in their optimal density in laboratory. 2. It was discussed the relationship between pneumococcal transformation formation and its opportunistic pathogenesis. Comparing their virulence with that of parental strains by challenging mice intraperitoneally and adhering to ECV-304 cell respectively.

First, this paper presents three girders model with double cable planes which main girder and side girder is connected by rigid arms, analyzes the dynamic characteristic of Yonghe cable-stayed bridge and obtains its natural vibration modes (i.e., frequency, damping values and the mode shapes ) by ANLSIS structural analysis program and uses these parameters as dynamic dactylogram of the intact case of cable-stayed bridge. Using the passage of random as the ambient vibration ,the dynamic properties of Yonghe Bridge is measured and the modal parameter of its 15 years after is identified and used as dynamic dactylogram of the damaged case. By the finite element analysis and locale vibration test, damaged and undamaged modal parameter is analyzed and curvature mode shape, which is sensitive to damage state, is introduced as possible candidate for identifying and locating damage in the cable-stayed bridge. Selecting the branch of part measured point from modal parameter, this paper deduces the damaged index which can detect the possible damaged location of the cable-stayed bridge deck and identifies the damaged region and degree for Yonghe Bridge. For the purpose of structural condition monitoring in in-situ , from another viewpoint, this paper introduces the method called the best optimization vector to detect damaged location and degree. The accuracy and reliability of the method presented in this paper are demonstrated by static analysis and test and the healthy state of Yonghe Bridge can be evaluated.
