Number of neural stem cells is small. NSCs look like circle or ellipse with or without short neurite, with large nuclear-cytoplasmic ratio and deep karyotin. NSCs have no visible differences with other kinds of cells in appearance, and have cell surface marker. Currently, there are mainly three aspects to identify NSCs: expression of specific nerve antigen, including nestin, Musashi, transcription factor, and cell adhesion molecules; self-renewal ability including single cell clone analysis, BrdU mark and S phase cell; the potential of multi-direction differentiation including immunocytochemical process and reverse transcriptase polymerase chain reaction.

由于神经干细胞的数量很少，从细胞形态来看神经干细胞为圆形或椭圆形，无或有较短的突起，核质比大，核染色较深，形态上与其它种类的细胞没有明显的差异，并且未找到一种细胞表面特异性标志物，因此目前鉴定神经干细胞主要有以下3个方面：特异性神经抗原的表达，包括巢蛋白、Musashi、转录因子及细胞黏附分子；自我更新能力，包括单细胞克隆分析、BrdU标记S期细胞；多向分化潜能，包括免疫细胞化学法、聚合酶链反应色法。

The cells infected and noninfected were combined with PLGA at a concentration of 5×106cells/ml to construct tissueengineered bones respectively.They were further implanted into 8 rabbits subcutaneously using PLGA as blank control(8 implants per group). Six weeks after surgery, the implants were evaluated with histological staining and computerized analysis of new bone formation.

方法］PLGA与腺病毒Ad-BMP-7感染后的兔MSCs共培养，电镜观察了解细胞在PLGA上黏附、生长和合成分泌骨基质成分的情况；将转染基因的细胞和未转染基因的细胞分别与PLGA支架复合，构建组织工程化骨并植入体内，通过组织观察新骨形成情况。

In order to study the therapeutic effect of Sodium Hyaluronate injection of articular cavity and taking orally "JIN GU TONG XIAO WAN"(JGTXW, a TCM preparation for osteopathy disease) in the treatment of osteoarthritis of knee, 130 cases of OA were randomly divided into the treated group (66 cases, treated by SH and JGTXW) and control groups(64 cases, treated only by SH); The effect such as local pain, tumidness, joint movement and so on of the two groups in one year were observed and evaluated according to Lysholm criterion.

骨性关节炎是一种常见的老年退行性关节软骨病，随着我国人口的老年化增高，发病亦越来越多，严重影响老年人的生活质量，对膝关节骨性关节炎的治疗方法多，但疗效都均不太理想，不能阻止或延缓疾病的进展，近年来，以透明质酸制剂为代表的氨基糖类黏弹性物质补充疗法，在防治OA的基础研究和临床应用上取得了良好效果，为OA治疗寻找到了新的途径〔1〕。

In the second part, we developed a new approach for the preparation of highly dispersed carbon black platinum nanoparticle with different geometric shapes by introducing clay (0 to 33%) as a dispersing agent in 5% Nafion co-solvent suspension without any organic solvents. FE-SEM analysis of CB/clay (100/0, 85/15, 67/33) was achieved CB particles with an average diameter of 40-60 nm. The hydrophilic property of the hybrid material was effectively improved in the presence of the clay was observed in sessile-drop test.

第二部分中我们发现在燃料电池之触媒制备常利用碳黑作为载体，碳黑在水中分散程度不一，而有机分散剂之电阻质较高常导致触媒用量提高增加成本，在本论文中我们利用几何片状结构的黏粒矿物与Nafion溶液做为分散剂巧妙的将碳黑分散，在不同黏土矿物与碳黑之不同比例(clay/CB 0/100， 15/85， 33/67)下进行分散，在SEM及TEM鉴定下证明其分散程度而碳黑粒径约40-60 nm。
