“易筋经”改善老年人微循环障碍和骨质疏松症的研究

根据“易筋经”健脾强肾和“易筋”的功法特点及肾虚、微循环衰退（障碍）是老年性病变之本的中医理论,我们在南京中医药大学和同济医科大学等有关部门的支持下,设立了《“易筋经”改善老年人体能（肌力）衰退、微循环障碍和骨质疏松症》的课题。上一阶段对改善体能、肌力衰退等方面的试点,已取得良好结果（参见本刊98第3期）《“易筋经”改善老年人体能衰近初探》）。本阶段主要是对练功者微循环障碍和骨质疏松情况进行观察研究,通过1年练功前后的数据对比,从“表1”可以看出,在甲过微循环的4项综合积分值中,有3项（形态积分值、流态积分值和总积分值）均有显著提高。“表2”是运用GZN－A型无创性人体骨矿物质含量测量仪对受试者掌院骨部骨皮质指数的检测数据表,其统动前后的指数也是普遍提高。因此,根据两表的检测结果可以认为“易筋经”的锻炼,对老年人微循环障碍和骨质疏松症的改善是有一定积极作用的。     

理论联系实际与图书馆学理论创新——兼与《理论联系实际是图书馆学发展的基础》作者商榷

文章认为理论联系实际不是图书馆学的发展基础,理论联系实际是图书馆学研究的科学学风,是图书馆学理论创新的重要途径,学术界对基础理论研究脱离实际的非理性责难是图书馆学发展的沉重枷锁,文章还就理论联系什么样的实际、理论怎样联系实际谈了自己的看法。

安徽省五批次传统村落演进过程及空间分布特征研究

传统村落承载着独特的地域性文化和古人生产、生活的传统智慧。将安徽省内五批次共400个的国家级传统村落纳入分析范围,分别运用SPSS进行基尼系数、洛伦兹曲线等描述性统计分析,ArcGIS进行最邻近距离、最邻近点指数和核密度等地理空间分析,探讨五批次传统村落空间分布演进的过程和特征。研究结果显示:①安徽省传统村落呈现非均衡凝聚型的空间分布特征,集聚形成皖南山区、皖西大别山形成两大核心区。②五批次传统村落空间分布的演进与高程、坡度、坡向等自然地理条件存在密切关联,主要分布在低海拔、缓坡、阳坡的地区。③五批次传统村落空间分布的演进与所在城镇GDP、道路交通等社会经济方面,集中分布在经济相对滞后地区,靠近道路和城镇的地区。④各个批次的传统村落各个形成年代均有之,其中隋唐五代形成的村落随批次逐渐减少,宋、元、明、清代随批次逐渐增加。     

我国图书馆公共关系的研究与实践

Since 1987,after the term "public ralation" was introducted into the Chinese Library circle,Library in China has experienced a change or a transition from simplicity to complication,form being scattered to systematic,from unconsciousness to consciousness and from a vague aim to a more definite one.From a point of view of the present situation,the development of public relation in the Chinese library circle is unbalanced.This problem remains to be solved by way of striving for the support and concerns of various callings at different levels in the society.     

中小学教师专业化存在的问题与对策

教师专业化已成为全球性的教育热点问题。在西方许多发达国家，非常重视教师专业化的理论探讨和研究，并积极推进有效的实践。在我国教师专业化起步较晚，从整体上讲水平不高，发展很不成熟，存在着许多亟待解决的问题。要提高我国中小学教师的专业化程度，应努力提高师范院校教师的专业化程度；积极稳妥地推进教师培养模式和课程的改革；建立规范化的管理体树；提高教师的经济待遇和社会地位。     

道家环境伦理思想的现实意义

法律自然化是中国传统法律化的又一重要特征。在中国化传统的发展和演变过程中，作为一种自然哲学形态的道家，其环境伦理思想是最为夺目的。本通过其自然主义的主体论、“道不私”的价值观、“道法自然”的方法论的论述，揭示了其对确立人与自然和谐相处理念的现实意义。

An exploratory study of the relationship between the use of the Learning Commons and students' perceived learning outcomes

This study proposes and empirically tests a model explicating the impact of the Learning Commons on university students' learning behaviors and skills development. Adapting the information literacy instruction model that is based on expectation disconfirmation theory, a series of hypotheses were developed, and data were collected through an online survey at a Hong Kong university. Responses from 388 students were subjected to a partial least squares structural equation modeling analysis. The results suggest that expectation disconfirmation theory can be applied in the domain of the Learning Commons, and that the degree to which students' expectations are confirmed affects their degree of perceived quality of and satisfaction with the Learning Commons. Perceived quality in turn influences satisfaction. Both perceived quality and satisfaction lead to psychological outcomes that produce behavioral changes and possible benefits, including time savings, effort reduction, better grades, advanced problem-solving skills, and improved learning outcomes.     

Inhibitory activities of microalgal extracts against Epstein-Barr virus DNA release from lymphoblastoid cells

This study aimed to assess the inhibitory activities of methanol extracts from the microalgae Ankistrodesmus convolutus, Synechococcus elongatus, and Spirulina platensis against Epstein-Barr virus (EBV) in three Burkitt's lymphoma (BL) cell lines, namely Akata, B95-8, and P3HR-1. The antiviral activity was assessed by quantifying the cell-free EBV DNA using real-time polymerase chain reaction (PCR) technique. The methanol extracts from Ankistrodesmus convolutus and Synechococcus elongatus displayed low cytotoxicity and potent effect in reducing cell-free EBV DNA (EC(50)<0.01 μg/ml) with a high therapeutic index (>28000). After fractionation by column chromatography, the fraction from Synechococcus elongatus (SEF1) reduced the cell-free EBV DNA most effectively (EC(50)=2.9 μg/ml, therapeutic index>69). Upon further fractionation by high performance liquid chromatography (HPLC), the sub-fraction SEF1'a was most active in reducing the cell-free EBV DNA (EC(50)=1.38 μg/ml, therapeutic index>14.5). This study suggests that microalgae could be a potential source of antiviral compounds that can be used against EBV.
