癫痫与免疫神经内分泌失衡有关

癫痫病是一种以脑部兴奋性神经元突然、过度放电为特征的慢性临床综合征.武汉同济医科大学博士生导师、知名中枢神经研究专家朱长庚教授等最近完成并通过验收的一项国家自然科学基金重点项目研究证实:"免疫、神经、内分泌三大系统不仅同时参与癫痫发病过程,且在神经与免疫、免疫与内分泌、内分泌与神经之间还存在着相互影响和作用,癫痫发病机理与免疫-神经-内分泌网络的功能失衡有关."     

神经内分泌——免疫网络

生命科学与人体健康单元的教学建议

高中《生物》选修教材中,生命科学与人体健康单元的教学目标主要是人体稳态与免疫。人体稳态中涉及内环境与稳态、水和无机盐的平衡与调节、血糖调节与体温调节;免疫部分主要为特异性免疫及免疫疾病。本单元的重点是稳态与特异性免疫,难点之一是找到消化、循环、呼吸、泌尿、神经、内分泌等系统的内在联系,形成稳态概念的知识网络;另一难点为免疫学原理及应用。免疫系统的基本概念及免疫学应用是新知识,区分好免疫学的相关概念,才能突破教学的难点。

慢性疲劳综合症是现代医学新认识的疾病,发病机制复杂.最近研究发现,细胞免疫功能和细胞因子表达的异常、内分泌功能的紊乱以及神经系统功能的异常可能参与该病的病理机制,因此神经内分泌免疫系统的失调是引发慢性疲劳综合症的重要因素.     

大鼠颌下腺ACTH和β-EP免疫组织化学研究

本研究应用免疲组织化学技术(PAP)法,对雄性wistar大鼠颌下腺进行促肾上腺皮质激素(ACTH)和β—内啡肽(β—EP)免疫组织化学定量研究,结果发现,在大鼠颌下腺的颗粒曲管,纹状管和小叶间导管存在不同强度的免疫阳性细胞,该实验结果进一步验证了颌下腺具有神经内分泌功能。     

褪黑素在应激性溃疡中的保护作用及其机制的研究进展

褪黑激素(MT)主要是由哺乳动物和人类的松果体产生的一种神经内分泌激素.MLT具有促进睡眠、调节时差、抗衰老、调节免疫、抗肿瘤等广泛生理功能,并且参与机体许多疾病或损伤的保护反应.以往的研究证明它具有很强的抗氧化活性,能直接清除氧自由基,增强抗氧化酶的活性,减少自由基的生成.近年来,很多研究逐渐重视MT在胃肠道中的作用,尤其对应激性溃疡中发挥的重要作用进行了广泛研究,并取得初步成果.     

学生应学会情绪的自我调控

风华正茂的学生。本该是最健康的一族，但许多调查资料显示，我国学生心理障碍和疾病的发病率高达20％，因各种疾病而休学、缓考的比例也呈上升趋势。造成学生身心不健康的原因是多方面的。但与情绪关系最为密切，特别是一些强烈而持久的异常情绪。对人危害更大。它一方面导致人大脑神经活动功能紊乱。使情绪中枢部位的控制减弱，使人认识范围缩小。自制力、学习效率降低，不能正确评价自我，结果强烈情绪愈演愈烈，造成某些失去理智的行为，产生心理障碍和心理疾病；另一方面，它又会破坏人体内生化保护机制。降低免疫功能，激化有害物质产生。导致正常生理平衡失调，引起心血管、消化、泌尿、呼吸、内分泌等系统的各种疾病。学生中的神经性头痛、神经衰弱、心律不齐、哮喘、神经性皮炎、月经不调等疾病都与情绪变化有关。     

ACTH对运动应激的反应与适应

在探索神经-内分泌-免疫网络间的复杂关系时,共同的生物活性媒介物质研究已成为解决问题的枢纽。认识生物活性物质相互作用关系和各自复杂功能,对于从整合视角认识运动人体特性具有重要意义。本文在简要分析促肾上腺激素的基础上,综述了促肾上腺激素对不同形式运动的反应与适应,并说明了影响这种反应与适应的主要因素。     

The current status of instructional design theories in relation to today's authoring systems*

It is of course very difficult to accurately project important characteristics of the future state of any rapidly evolving field, and the field of authoring systems for computer‐assisted instruction (CAI) is no exception. However, strong trends in evolving CAI systems of today would seem to indicate some important characteristics of the software systems underlying tomorrow's automated instructional systems. Under the premise that form follows function, this paper will explore the functional impetus of some of the most important trends extant in terms of their roots in a powerful, emerging technology of instructional design. This technology promises to complement the advancing hardware and software technologies, by supplying that sine qua non of successful instructional materials. It is inevitable that systems of the future will make (and indeed are making) significant accommodations of this vital technology as it matures, and therefore some important characteristics of tomorrow's systems can be predicated upon what is already known of this technology of instructional design.     

A Soft OR Approach to Fostering Systems Thinking: SODA Maps Plus Joint Analytical Process

Higher order thinking skills are important for managers. Systems thinking is an important type of higher order thinking in business education. This article investigates a soft Operations Research approach to teaching and learning systems thinking. It outlines the integrative use of Strategic Options Development and Analysis maps for visualizing and assessing systems thinking and the joint analytical process for systems thinking development. This approach has been applied in an MBA course, and has demonstrated its usefulness for students in developing systems thinking skills.     

Academic quality,league tables,and public policy: A cross-national analysis of university ranking systems

The global expansion of access to higher education has increased demand for information on academic quality and has led to the development of university ranking systems or league tables in many countries of the world. A recent UNESCO/CEPES conference on higher education indicators concluded that cross-national research on these ranking systems could make an important contribution to improving the international market for higher education. The comparison and analysis of national university ranking systems can help address a number of important policy questions. First, is there an emerging international consensus on the measurement of academic quality as reflected in these ranking systems? Second, what impact are the different ranking systems having on university and academic behavior in their respective countries? Finally, are there important public interests that are thus far not reflected in these rankings? If so, is there a needed and appropriate role for public policy in the development and distribution of university ranking systems and what might that role be? This paper explores these questions through a comparative analysis of university rankings in Australia, Canada, the UK, and the US.

Qualities of classroom observation systems

ABSTRACT

Observation systems are increasingly used around the world for a variety of purposes; 2 critical purposes are to understand and to improve teaching. As observation systems differ considerably, individuals must decide what observation system to use. But the field does not have a common specification of an observation system, nor does it have systematic ways of thinking about how observation systems are similar and different. Given this reality and the renewed global interest in observation systems, this article first defines the observation system concept and then presents a framework through which to understand, categorize, and compare observation systems. We apply the framework to 4 well-known observation systems that vary in important ways. The article concludes with a discussion of the results of the application of the framework and some important implications of those findings.

Complex Systems in Education: Scientific and Educational Importance and Implications for the Learning Sciences

The multidisciplinary study of complex systems in the physical and social sciences over the past quarter of a century has led to the articulation of important new conceptual perspectives and methodologies that are of value both to researchers in these fields as well as to professionals, policymakers, and citizens who must deal with challenging social and global problems in the 21st century. The main goals of this article are to (a) argue for the importance of learning these ideas at the precollege and college levels; (b) discuss the significant challenges inherent in learning complex systems knowledge from the standpoint of learning sciences theory and research; (c) discuss the "learnability issue" of complex systems conceptual perspectives and review a body of literature that has been exploring how learning sciences pedagogical approaches can lead to student learning of important dimensions of complex systems knowledge; (d) argue that the cognitive and sociocultural factors related to learning complex systems knowledge are relevant and challenging areas for learning sciences research; and (e) consider ways that concepts and methodologies from the study of complex systems raise important issues of theoretical and methodological centrality in the field of the learning sciences itself.
