Injectable hybrid inorganic nanoscaffold as rapid stem cell assembly template for cartilage repair

Cartilage injuries are often devastating and most cannot be cured because of the intrinsically low regenerative capacity of cartilage tissues. Although stem-cell therapy has shown enormous potential for cartilage repair, the therapeutic outcome has been restricted by low survival rates and poor chondrocyte differentiation in vivo. Here, we report an injectable hybrid inorganic (IHI) nanoscaffold that facilitates fast assembly, enhances survival and regulates chondrogenic differentiation of stem cells. IHI nanoscaffolds that strongly bind to extracellular matrix (ECM) proteins assemble stem cells through synergistic 3D cell–cell and cell–matrix interactions, creating a favorable physical microenvironment for stem-cell survival and differentiation in vitro and in vivo. Additionally, chondrogenic factors can be loaded into nanoscaffolds with a high capacity, which allows deep, homogenous drug delivery into assembled 3D stem-cell-derived tissues for effective control over the soluble microenvironment of stem cells. The developed IHI nanoscaffolds that assemble with stem cells are injectable. They also scavenge reactive oxygen species and timely biodegrade for proper integration into injured cartilage tissues. Implantation of stem-cell-assembled IHI nanoscaffolds into injured cartilage results in accelerated tissue regeneration and functional recovery. By establishing our IHI nanoscaffold-templated 3D stem-cell assembly method, we provide a promising approach to better overcoming the inhibitory microenvironment associated with cartilage injuries and to advance current stem-cell-based tissue engineering.     

Historicising teachers’ learning: a case study of productive professional practice

This paper reveals the significant historical traces which informed the learning practices of teachers at one particular school site in a rural and regional educational district in Australia. Drawing upon recent theorising into professional practice, the paper argues that teacher learning practices are intrinsically ‘ecologically’ related to teachers’ practices at specific sites. However, extending beyond this theorising, the research also reveals how teacher learning – in the case presented, in relation to classroom dialogue – is also significantly influenced by earlier learning experiences of the teachers involved. In this way, teachers’ practices are revealed as not only influenced by present-day, site-specific, whole-school teacher learning, but also by particular events encountered by teachers at an earlier phase of their careers. The research argues for a conception of teachers’ learning which is not only site-informed and ecologically arranged, but also deeply temporally embedded.     

中医非药物疗法对癌症患者免疫力的影响

中医讲＂正气存内,邪不可干＂这里的＂正气＂指人体的抗病能力,相当于西医讲的人体免疫力,肿瘤疾病的发生发展在某种意义上是人体的＂正气不足＂所引起的,它是内因是决定性的因素。就＂驱邪扶正＂提高肿瘤患者的人体免疫力这一难题,传统中医的非药物疗法就有其＂独到之处＂,其方法简便、价格低廉、主治广泛、疗效肯定、无毒副作用等优点,符合健康观念总体需求,也符合生物-心理-社会的现代医学模式。文章就此只论述三种疗法,情志疗法、音乐疗法和气功疗法。     

siRNA抗肝癌国内研究进展

综述了国内siRNA在肝癌治疗中的研究现状．在肝癌治疗中,运用siRNA技术构建相应的siRNA载体,分别作用于与肝癌发生相关的癌基因、抑癌基因及其他相关因子等,可在一定程度上抑制癌基因表达、抑癌基因突变、细胞周期素的过度表达、过度表达的生长因子和受体以及肝癌细胞的侵袭转移能力．这些方面的研究均取得了可喜的成果,部分研究已从体外试验过渡到体内试验,为肝癌的临床治疗奠定了基础．siRNA技术为肝癌以及其他肿瘤的治疗开辟了一条新途径．但siRNA技术作为一项即将应用于临床的新技术仍存在许多问题,因此,作为临床治疗目前条件尚不成熟,仍需进一步研究．     

反思与争鸣：缔造中国武术的生存空间

文章采用文献资料法、逻辑分析法,运用文化学、历史学等相关理论,以中国武术为研究对象,从民族文化视角来研究中国武术的发展问题。中国武术作为民族文化的一种符号和身份象征,要走出“文化失语”的困惑,要敢于同历史对话、同现实对话、同自己对话。要调整自己的文化立场,开拓属于自身的生存空间,最终也守护着民族文化的大空间,延续着民族的文明进程。     

Resting Bradycardia,Enhanced Postexercise Heart Rate Recovery and Cardiorespiratory Fitness in Recreational Ballroom Dancers

Purpose: In a cross-sectional study design, we evaluated the resting heart rate (HR_baseline) and exercise and postexercise stress test-related chronotropic responses in male practitioners of recreational ballroom dancing (BD; n = 25, M_age = 26.6 ± 6.1 years) compared to a control group of insufficiently active nondancers (CG; n = 25, M_age = 25.9 ± 4.5 years). Method: All participants underwent a submaximal exercise test. At 85% of the maximal predicted HR, the recovery protocol was started, and heart rate recovery (HRR) was recorded during 1-min intervals for 5 min. Results: Compared with CG, BD showed lower HR_baseline (70 beats per minute [bpm] vs. 62 bpm, respectively, U = 143, p < .05, ES = .46), lower preexercise HR (94 bpm vs. 86 bpm, U = 157, p < .05, ES = .42), longer exercise test duration (346 s vs. 420 s, U = 95.5, p < .05, ES = .59), and higher HRR for 5 min postexercise (U = 1.29–1.89, p < .05, ES = .33–.50) as follows: 1st min (32 bpm vs. 40 bpm), 2nd min (45 bpm vs. 53 bpm), 3rd min (51 bpm vs. 58 bpm), 4th min (55 bpm vs. 59 bpm), and 5th min (59 bpm vs. 63 bpm). The coefficient of HRR from the 1st min to the 5th min postexercise was similar in both groups (U = 229–311, p > .05, ES = < .10–.22). Conclusion: Heightened cardiovascular functional status characterized by favorable enhanced chronotropic dynamics appears to occur in practitioners of recreational ballroom dancing, which suggests that this modality of exercise may result in health benefits.

论体育康复的特点和作用

体育康复是体育与医学相结合的一门新兴学科，在现代文明高度发展的今天，体育康复的功能与作用已充分得到显示，但是，作为一门交叉学科，其理论研究在国内仍十分薄弱。笔者用体育康复的整体性观念，对疾病和治愈赋予新的解释，提出在实施体育康复的过程中要注意掌握和运用的“三个统一”；强调体育康复过程中内因的作用，主张通过具体矛盾的分析选用相应的治疗手段；提出把人体功能的恢复与改善作为体育康复的重要任务；阐明体育康复在预防、治疗和康复过程中的重要作用，以及体育康复与其它医学门类的相互联系；强调体育疗法在体育康复中的重要地位等。
