尼莫地平对阿尔茨海默病大鼠脑组织NO、NOS含量及行为学的影响

目的：探讨尼莫地平对阿尔茨海默病（AD）大鼠脑组织一氧化氮(NO)、一氧化氮合酶（NOS）浓度及行为学改变的影响。方法：SD大鼠30只，随机分为空白对照组,AD模型组和尼莫地平组，采用大鼠脑组织立体定位微量注射技术，尼莫地平组和AD模型组用鹅膏蕈氨酸（IBO）1μl(5μg)损毁大鼠双侧迈内特基底核（nbM）建立AD动物模型，空白对照组以0.1mol/L pH7.4PB液代替IBO。尼莫地平组给予尼莫地平0.5mg/kg，空白对照组和AD模型组以生理盐水代替尼莫地平，连续灌胃60d，每d2次，每次2ml。做迷宫试验及跳台试验测学习记忆能力，然后将大鼠断头处死，分离海马及大脑皮质，分别检测NO,NOS含量。结果：AD模型组较空白对照组学习记忆能力显著降低，海马及大脑皮质NO,NOS含量显著升高，尼莫地平较AD模型组学习记忆能力显著升高，海马及大脑皮质NO、NOS含量显著降低。结论：用IBO损毁大鼠双侧nbM可建立AD动物模型，尼莫地平可显著改变AD模型大鼠的学习记忆能力，降低海马及大脑皮质NO、NOS含量。     

引导科技干部保持医院发展转型期间和谐心态的着力点

当前部队医院正处于发展转型期，如何引导科技干部适应转型发展新形势，经受住各种考验，始终保持理性平和、协调平衡、积极向上的心理状态，是一个不容忽视的现实问题，也是事关医院内部和谐和医院建设发展又好又快的大事，更是我们思想政治工作者必须着力认真研究、加以解决的重要课题。     

How to Effectively Implement an Indicator System to Improve Performance from a Management Perspective: The Case of Taiwan Healthcare Indicator Series (THIS) System

This study uses the Taiwan Healthcare Indicator Series (THIS) system as an example to examine which determinants would improve performance by sharing indicators from a management perspective. This study population included all 227 hospitals participating in the THIS system in 2006. A structured questionnaire was sent to the director who was responsible for the THIS system via electronic mail. A total of 111 responses were returned by February 10, 2006. Questions included current implementation and impacts of the system. Hierarchical regression models were performed to identify which variables were significantly associated with performance improvement, adjusted for hospital characteristics. Four variables significantly associated with implementing the THIS system to improve performance were ‘senior management support,’ ‘benchmarking,’ ‘making departments improve the underperforming indicators and report the improvement results in performance management meetings,’ and ‘integration with the National Health Insurance payment regulations’. This study contributes substantially to the evidence base about what works to improve performance by information sharing. Although information sharing is the basis of efforts to improve performance, senior management support and how to effectively apply the information are the most important determinants of performance enhancement.     

提高中医临床疗效的科学学检讨(连载三)

中医学的生命力在于临床疗效 ,社会对于中医学的需要也在于临床疗效。提高中医临床疗效的科学学研究 ,要以中医基础理论为依据 ,以理、法、方、药一脉相承的辨证论治为前提。造成中医临床疗效下降的问题在于“三个脱节” ,即中医学与自身文化基础脱节 ,中医临床与辨证论治脱节 ,中药与中医临床脱节。中医学正处于行将消亡的边缘 ,也处在新的突破的前夜。实事求是地进行科学、历史的反思 ,中医学完全有可能走出百年困惑 ,得到振兴和发展。     

对－苯二甲酸衍生物的合成及其诱导分化HL－60细胞的活性

作者合成了１３个对－苯二甲酸衍生物，其中有９个化合物尚未见文献报道。通过对ＨＬ－６０细胞诱导分化活性试验，发现有两个化合物在浓度为５×１０￣（－６）ｍｏｌ／Ｌ时，可使细胞分化率达５５％，低于维Ａ酸的分化率（７９％，１０￣（－７）ｍｏｌ／Ｌ）。     

将素质教育理念贯穿在生化课教学中的探索

为适应知识经济时代对医学人才培养的要求,应将素质教育引入生化教学中。本文从提高教师综合素质,生化课堂教学、第二课堂教育,多媒体应用等方面入手,探索在生化课教学中提高学生素质的有效途径,以全面提高教学质量,实现对医学人才的培养目标。     

方剂学科发展思路与方法

方剂学科传统模式已发生重大变化，现代方剂学以计算机和实验为重要研究手段，熔理论方剂学、实验方剂学及临床方剂学于一炉。现代方剂学科模式的建立必将培育出新的知识增长点，丰富学科内涵，促进研究方向和专业课程的调整，提高学术水平和人才培养质量，实现新世纪方剂学科发展质的飞跃。     

Basic sciences in problem-based learning and conventional curricula: students' attitudes

The purpose of this study was to compare the attitudes toward basic sciences of students in a preclinical problem-based curriculum and a conventional lecture-based curriculum at the end of their second year of medical school. The results showed that the PBL class had more positive attitudes toward basic sciences than students in the conventional class. These results may reflect a learning environment where students meet many scientist role models as teachers and where basic science is learnt in the context of clinical problems.
