Fund Project: the National Natural Science and Technology Source Program, No. 2001DEA1006*Abstract: 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 no 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 Lace-up group's center of pressure displacement quantity is bigger than other two groups,therefore its balance ability is also bad, therefore suggested the athlete when wearing ankle braces sports should inquire specialized doctor and the protection suggestion avoids injury.
人体在穿戴不同踝部护具执行单脚著地后迅速推蹬动作时, Lace-up和Air stirrup这两种护具在著地期间确实具有限制关节活动度的效果,但也因踝关节跖屈能力的下降造成人体著地时缓冲地面冲击力能力下降的现象,造成本研究结果在地面反作用力垂直分力Lace-up和Air stirrup组都较赤足组来的较大,著地时脚的负荷率Lace-up组和Air stirrup组都较赤足组来的较大,且Lace-up组在著地期压力中心偏移量也较其他两组大,故其平衡能力也有差异,故建议运动员在穿著踝部护具运动前应询问专业医师及防护员的建议以避免因此而受到伤害。
