体育慕课现象的现实反思与未来展望

慕课作为在线教育的延伸和拓展,蕴涵多种教育理念。在信息技术持续创新的新时代,体育慕课存在慕课的使用范围有限、学生类型与学习成效面临质疑、慕课的教与学存在困难、教学成本与质量存在二维背离的发展困境。重新审视与反思慕课,发现：技术性工具难以带来教育真正的变革、慕课反映了我国教育界缺乏文化自信的心态、本土教育机制生长点的缺乏将颠覆抑或融合慕课的作用。最后提出：以体育慕课发展为契机推进学习型社会的转变、打造精品体育慕课满足学习者多元需求、建立慕课学习过程为内核的监管机制来提高教育质量,形成合力推进体育慕课持续发展等未来发展趋向。     

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.     

写作的心理治疗与辅导:功能、原理及其应用

写作具有宣泄、抚慰、重构认知功能,从而在心理治疗中发挥着独特的作用。写作治疗的基本原理包括:降低压力经验的通达性,减少闯入记忆;形成叙事连贯,达到因果认识与领悟;对事件整合和重构,建构另种生活故事;把问题外化。写作治疗与辅导中的治疗性写作主要包括了日记、信件、自传和主题写作等类型。     

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．     

网络环境中学习者反思行为的向度分布研究

反思可以看作为网络学习环境下学习行为的一种高阶能力,通过网络学习环境中的学习者反思行为的研究分析对提高网络学习的效果有重要的作用。采用试验研究,通过编码分析学习交互中的反思行为数据,探究学习反思行为的向度分布。结果发现,网络学习环境下学习者的反思分布主要是在认知领域的,在行为和情感领域的反思还比较欠缺;在班级和性别上反思的分布均存在某种差异。     

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.
