难治性黄疸动物模型研究

目的：为难治性黄疸研究找到一种较为合适的动物模型。方法：１６只狗胆管壁浸润注射１％甲醛,１月内观察胆汁粘度和管壁病理形态学变化。结果：注射后胆管粘膜有进行性加重的炎症、粘膜脱落、纤维化及乃至管腔狭窄,其病理变化及临床的硬化性胆管炎病理特征基本符合。结论：本模型可望成为研究难治性黄疸的较为实用的动物模型。     

简易切割法制作健康SD成年大鼠hSCI和tSCI模型

用简易切割法制作ｈＳＣＩ和ｔＳＣＩ模型。４５只ＳＤ大鼠随机分为３组。ＩＳＣ组６只,ｈＳＣＩ组１８只,ｔＳＣＩ组２１只。用显微剪在Ｔ１３－Ｌ间横几完全剪断脊髓或其一则１／２,制成ｔＳＣＩ和ｈＳＣＩ模型,术后动态行为观察和神经功能综合评价,并分别于术后２４ｈ,７ｄ取Ｔ１１－Ｌ３节段脊髓作冻冻切片苏木精染色观察。结果显示,３组间ＣＢＳ两两比较经ｑ检验均有显著性差异。病理改变,ｈＳＣＩ组主要是伤侧伤质缩小     

大鼠拟血管性痴呆模型的建立及中药9602防治作用初探

用反复夹闭双侧颈总动脉(CCA)结合腹腔注射硝普钠将血压降低到50mmHg左右的方法复制了大鼠拟血管性痴呆的模型。结果表明脑缺血再灌注后7 d,行为学实验显示模型组大鼠出现明显的学习记忆障碍;形态学观察发现海马CA1区出现明显的细胞缺失,而CA3区无明显变化。中药9602可明显减轻脑缺血对海马的损伤,改善脑缺血引起的学习记忆障碍的作用。     

Richmond-Kotelchuck健康政策模式图的启示──我国预防医学模式转变中的三个关键问题

Richmond－Kotelchuck的健康政策模式图由科学知识基础、政治意愿和社会行为措施三部分组成。该模式图充分体现了三者对整个健康政策模式图的作用及其相互联系。随着社会的发展,我国当前正面临着转变预防医学模式的任务,借助于该模式图,本文论述了我国预防医学模式转变中值得注意的三个关键问题：科学研究、健康教育和举措设计。     

医疗纠纷处理模式的若干问题探讨

目前,医疗纠纷的数量急剧上升,现有的法规已难以适应形势的发展,医疗事故鉴定结论的公正性日益受到患者的质疑,其提出的高额赔偿要求已远远超过各省市现行规定的标准。医院管理者作为解决医疗纠纷的一线人员,普遍感到现有法规已难以操作。本文提出以完善立法为基础的几项改革措施：（１）成立卫生法庭（２）建立医疗风险保险（３）加强以行医执照的基础的行业管理（４）加快养老、医疗、残疾等社会保障制度的综合改革步伐。以此     

Humiliation: Assessing the Impact of Derision, Degradation, and Debasement

This paper describes the development of a self-report scale to assess the internal experience of humiliation. After defining the construct, an item pool of 149 items was generated, utilizing a five-point Likert scale response format. A sample of 253 individuals ages 15 to 51 (M= 20.66) was used to conduct the item trial. The item pool was evaluated through item and factor analyses. Factor analysis identified two correlated factors accounting for 58% of scale variability. The 20 items loading on factor one were labeled the Fear of Humiliation Subscale and the 12 items loading on factor two were labeled the Cumulative Humiliation Subscale. The full scale of 32 items is called the Humiliation Inventory. Reliability analyses indicate that the subscales and the full scale have high internal consistency. Exploratory analyses of mean scores across six demographic groups indicate significant differences between male and female mean scores on the total scale and the two subscales.     

Innovation as hospital culture: a trial and demonstration facility in an acute-care hospital ward

This short communication describes the establishment of a trial and demonstration facility for new products, technologies, methods and procedures in an acute-care hospital ward at Concord Hospital in Sydney, Australia. The importance of innovation for all businesses, including hospitals, is discussed; and, why a project like the Model Ward can promote innovation as part of the corporate culture. The Model Ward development, implementation and its benefits are reported on and discussed.     

论中医"藏象"思维模型及其对系统复杂性研究的意义

构成人体子系统间的关联关系复杂 ,并且人体能不断与外界进行物质、能量、信息的交换 ,因此人体是一个开放的复杂巨系统[1] 。中医以其独特的研究方法和认知模式 ,能够有效地分析人体复杂的生命现象和维护人体的健康。本文认为思维模型的运用 ,是中医研究人体的基本手段和方法。思维模型不是利用物质实物做模型 ,而是在人们的思维中对认识对象的一种纯化、简化的映象 ,它是抽象的 ,是思维形式的模拟物 ,需要用思维把握[2 ] 。本文就中医“藏象”思维模型的建构过程、特点及其对人体系统复杂性研究的意义 ,探讨如下。1　“藏象”是中医认识人…
