关键词： Interactive learning environments   Media in education   Teaching/learning strategies   Improving classroom teaching  

摘要： This study provides an understanding of how different interactive technology tools that are integrated into a Website can be used for teaching undergraduate human anatomy and physiology laboratory students. Technology tools refer to a Website that the authors created to teach the Cardiovascular System that includes dynamic tools such as the Pronunciation Corner and Spelling Bee, and an Interactive practice and test tool. The Cardiovascular System was chosen as the subject matter to modify based upon the results of a pilot study where students indicated difficulty in understanding this subject. In addition, a "Teacher Resources" tool on the Website allows any teacher to create their own Pronunciation Corner and Spelling Bee and use them for their classes. The statistical analyses showed that the experimental group students (who had access to the Website) took advantage of the technology tools provided and demonstrated significant improvement in their performance on the cardiovascular portion of the lab test.

摘要： Cell-based assays have become important tools in the pharmaceutical and biotechnology industries. However, observing and monitoring molecules in cells that mimic the physiological environment is often difficult. Dynamic processes not only increase the accuracy of simulations, but also improve our understanding of the function and regulation of molecules within cells. In this study we used chitosan as a multifunctional biomaterial for selective micropatterning of cells, peptide delivery and covalent bonding with quantum dots (QD) to decrease the cytotoxicity of QD. Our results demonstrate the efficacy of chitosan-QD-peptide-Alexa Fluor 488 in controlling the spread and spatial organization of cells. Cationic chitosan also provided an efficient delivery mechanism to live cells. We used the shift from green to red fluorescence of the chitosan dual color QD peptide to detect biological activity. This methodology has potential applications in high throughput screening of inhibitors and activators of biological mechanisms and pathways and for use in the pharmaceutical industry.

关键词： 神经系统损害   急性铊中毒   临床研究   中毒性   神经电生理学   器官系统   临床表现   临床特点  

摘要： 铊属于高毒类，可引起多器官系统的损害，临床表现多种多样，神经系统为其最主要的靶器官，其损害也较为严重和持久。本文主要对急性铊中毒所致神经系统损害的临床特点及其病理、神经电生理学等相关研究进行综述。

关键词： PBL教学法   医学教育   医学生理学   教学方法  

摘要： PBL（Problem-Based Learning）意为以问题为基础的学习,目前已成为国际上一种十分流行的教学方法[1]。生理学是医学教育中一门十分重要的基础课程,但是生理学的内容繁杂,结构细微,比较抽象,不易理解,有些同学会因为这些原因而放弃学好这门课。针对这一特点,我们在生理学的部分章节中引入了PBL教学法,并根据需要在其含义上加以扩展,收到良好效果。

关键词： 生理学实验   充分   合理   利用  

摘要： 生理学是生物科学中的一门重要学科。生理学的理论知识主要是通过实验获得的,因而生理学实验对医学生掌握人体生理学基本理论和基础知识,培养学生基本实验技能及实践能力和科研能力有重要的作用。在生理学实验中常用的动物是两栖类的蛙（蟾蜍）和哺乳动物类的家兔,

关键词： 生理学教学   合作学习   学习方式  

摘要： "合作学习"是自主学习的一种形式,它作为一种新型的学习方式,一般包括同伴互助合作学习、小组合作学习、全员合作教学三种主要形式。本文阐述了在运动生理学教学中如何开展合作学习,培养学生与他人合作的意识及合作学习过程中应注意的问题。使合作学习这种学习方式更科学、更合理。

关键词： 生理学   实验教学   青年教师  

摘要： 生理学是教育部和卫生部于2008年10月颁布的《本科医学教育标准》中,列为医学生的一门重要的基础医学课程。作为生理学科的青年教师,在走向教育工作岗位时,通常是首先进行实验课教学。如何教好生理学实验课,结合实践体会,与青年教师们共同交流探讨。
