以工程素质培养为导向的生物工程专业核心课程改革

探讨以注重综合素质、强化工程能力和工程素质的培养、完善知识结构为重点的生物工程专业核心课程的教学改革。阐明生物工程师应具备的以五种能力和五种意识为核心的工程素质内涵,明确培养工程素质实施的核心课程;充分利用产学研平台,建设素质精良的"双师型"教师队伍;以工程能力培养为主线,建立以生物工厂设计和工艺改进的教学特色课程群;实施启发式、分组讨论法、比较归纳法和案例式的教学方法改革,提高了教学效果,强化了生物工程专业学生工程素质的培养。     

动物福利在研究生实验动物学教学中的应用初探

在医学研究中,实验动物具有不可替代的地位和作用,越来越多的人开始关心动物福利。各医学院校是培养未来科研工作者的机构,实验动物在医学院校的使用量非常大,因此,在课堂教学中,培养医学生树立保护动物福利的观念具有重要意义。本文从课堂教育、实验动物处理、3R原则的实施等方面探讨了如何在教学过程中开展动物福利教育。     

微生物学发展史在教学中的作用初探

以微生物发展史贯穿教学, 在教学过程中穿插中外科学家对学科的贡献及科学研究的艰辛历程, 不仅提高了学生的学习兴趣, 而且使其对科学研究有了初步认识。80%以上的学生取得较好的成绩。     

《微生物工程》课程教学探索与改革

结合“微生物工程”课程的教学实践, 通过实施整合优化课程体系、改进教学方法以及建立多层次的实验教学体系等方面的改革措施, 以期达到提高教学质量、提升学生的综合素质和创新能力的目的。     

强化实验教学管理 提高组织学与胚胎学实验教学效果

组织学与胚胎学（组胚）是医学教育重要的基础课程。随着医学教育改革的深入发展,我们通过适时调整实验教学大纲,在科室合作、教师培养、集体备课、多媒体教学、开放实验室、和实验教学档案管理等方面加强了对实验教学的管理,以提高组胚实验教学效果。     

研究生精品课程建设——《医学发育生物学》

医学发育生物学是随着生命科学领域各学科的发展,尤其是发育生物学和医学的发展而逐渐建立起来的一门新型学科。本文结合在精品课程建设中的实践体会,根据医学发育生物学课程的特点,针对该课程教学过程中存在的问题,从培养学生的创新精神与实践能力出发,重点介绍该课程教学内容改革、教材建设、实践环节和教学方法手段改革等方面的思路。     

Web-based weight management programs in an integrated health care setting: a randomized, controlled trial

Objective: To assess the efficacy of a Web‐based tailored behavioral weight management program compared with Web‐based information‐only weight management materials. Research Methods and Procedures: Participants, 2862 eligible overweight and obese (BMI = 27 to 40 kg/m²) members from four regions of Kaiser Permanente's integrated health care delivery system, were randomized to receive either a tailored expert system or information‐only Web‐based weight management materials. Weight change and program satisfaction were assessed by self‐report through an Internet‐based survey at 3‐ and 6‐month follow‐up periods. Results: Significantly greater weight loss at follow‐up was found among participants assigned to the tailored expert system than among those assigned to the information‐only condition. Subjects in the tailored expert system lost a mean of 3 ± 0.3% of their baseline weight, whereas subjects in the information‐only condition lost a mean of 1.2 ± 0.4% (p < 0.0004). Participants were also more likely to report that the tailored expert system was personally relevant, helpful, and easy to understand. Notably, 36% of enrollees were African‐American, with enrollment rates higher than the general proportion of African Americans in any of the study regions. Discussion: The results of this large, randomized control trial show the potential benefit of the Web‐based tailored expert system for weight management compared with a Web‐based information‐only weight management program.     

护理本科生对毕业论文认知情况的调查分析

目的：调查护理本科生对毕业论文的认知情况、参与科研的能力和积极性,分析其科研素质现状,以便改进护理研究实践、教学与管理工作,提高护理本科生的科研能力。方法：采用自制问卷的方式对某医科大学2002级护理本科85名同学进行调查研究。结果：81.58％的学生认识到写毕业论文的必要性,98．68％的学生表示重视,71．05％的学生认为要求过高,84．21％的学生认为困难很大、难以应付,43．42％的学生在这一过程中存在一定的被动性。结论：护理本科生科研意识比较淡薄,科研思路不清晰,存在被动性,今后应加强护理本科生的科研训练,提高指导老师的论文指导水平,增强护理本科生的科研能力。     

Description and analysis of two internet-based databases of insect pathogens: EDWIP and VIDIL

In 1996, two searchable databases covering insect pathogens were posted on the World Wide Web: the Ecological Database of the World's Insect Pathogens (EDWIP) and the Viral Diseases of Insects in the Literature database (VIDIL). In this paper, we describe the format and contents of EDWIP and VIDIL on the World Wide Web. EDWIP contains over 9,400 pathogen-host association records, 677 negative test result or "no association" records, 4,454 host species, 2,285 pathogen species records, and 2,057 bibliographical references. Species of Coleoptera and Lepidoptera are the best represented groups in EDWIP. Lepidopteran species account for the most associations of any host order in EDWIP, over 2,500, or 27%. Of the pathogen groups, Protozoa (including microsporidia) accounted for nearly 66% of the pathogen species records and over 40% of the association records in EDWIP. Fungi account for only 18% of the pathogen species, but nearly 33% of the association records. Habitats dominated by human activities (e.g., crop, stored product, and human dwelling) account for most of the host habitats recorded in EDWIP. The United States and Japan are the most common locations and the Nearctic and Palearctic are the most common biogeographic regions reported in EDWIP. There are 4,801 annotated bibliographic records in VIDIL.
