两种术式治疗老年椎体骨质疏松性压缩骨折的循证思考

椎体成形术(PVP)与球囊扩张椎体后凸成形术(PKP)是目前临床上常用的治疗老年椎体骨质疏松性压缩骨折有效方法。针对两者的优缺点,利用比较治疗学相关原理和方法,从其生物力学、适应证、疗效、并发症及费用等方面进行比较,以获得启示,为临床实践提供指导。     

Poles of Meaning: Pushing Language Up and Down

I discuss the problem of using the emotional/cognitive duality as a satisfactory way of formulating the problem of linguistic origins and of the distinctiveness of literary language. I address in particular Shanahan’s use of the work of Ernst Cassirer and Susanne Langer. I point out that Cassirer offers us a multileveled model of language’s sense-functions which avoids false oppositions and that Langer shows that literature does not belong to the discursive but to the presentational order of symbolism. Such insights strengthen rather than weaken Shanahan’s main points about the ‘localization’ and nature of meaning.

从系统论看肿瘤的生物靶向性治疗

肿瘤的生物靶向性治疗是恶性肿瘤治疗的新方法,其试图通过在基因水平上调节与肿瘤发生、发展有密切联系的生命物质来达到治愈肿瘤的目的。但临床运用中,生物靶向性治疗的疗效与我们的想象相去甚远。本文运用系统论的观点,分析目前生物靶向性治疗中存在的问题及寻求可能解决的方法。     

浅析中药现代研究的困惑,探究研究策略

中药现代研究是当前医药学界的热点和重点研究领域。在面对中药现代研究取得的某些方面”突破”的同时,也须正视中药现代研究的困惑。从中药研究所面临的困惑出发,探究中药现代研究的出发点、立足点、关键点和突破点,有助于理清研究思路,明确研究方向,确定研究方法与目标,促进中药现代研究的进程。     

IMAGINATION'S GRIP ON SCIENCE

Abstract: In part because “imagination” is a slippery notion, its exact role in the production of scientific knowledge remains unclear. There is, however, one often explicit and deliberate use of imagination by scientists that can be (and has been) studied intensively by epistemologists and historians of science: thought experiments. The main goal of this article is to document the varieties of thought experimentation, not so much in terms of the different sciences in which they occur but rather in terms of the different functions they fulfil. I argue that thought experimentation (and hence imagination) plays a role not only in theory choice but in singular causal analysis and scientific discovery as well. I pinpoint, moreover, some of the rules governing the use of thought experiments in theory choice and in singular causal analysis, that is, some of the criteria they should meet in order to fulfil those functions successfully.     

毛泽东与毛泽东思想的宣传

人们对毛泽东思想的学习、宣传与毛泽东本人有密切关系。在民主革命时期,毛泽东对毛泽东思想宣传有发起作用。1950年以后,从大规模普及毛泽东思想到“文化大革命”期间大力宣传毛泽东思想,都与毛泽东努力捍卫自己的思想使之在实践中不受干扰分不开。只有正确说明毛泽东怎样看待人们对自己思想的宣传和学习,才能真正完整叙述毛泽东思想及对其宣传的历史。     

摆在现代外科医师面前的若干矛盾现象

随着自然和社会科学的进步,现代外科在得到了空前发展的同时,许多矛盾现象也摆在外科医师的面前,例如手术和非手术、手术扩大与缩小、手工操作和器械使用、手术实施和手术风险、经验主义和循证、临床治愈和健康之间的矛盾,如何正视和解决这些矛盾问题,关系到到现代外科学长远发展。     

急性有机磷农药中毒救治中的几个问题

解决急性有机磷农药中毒病死率居高不下的问题,必须提高救治中的辩证思维。正确理解标本兼治的含义,外周性、中枢性抗胆碱药物和复能剂联合应用,合理维持阿托品化,积极应用机械通气进行必要的呼吸支持治疗和适时行血液灌流治疗是救治有机磷农药中毒的有效保证。     

Modern racism and neo‐liberal globalization: the discourses of plausible deniability and their multiple functions

Recently, considerable energy has been focused on extending the mandate of anti‐racism. Modern (or symbolic) racism and discursive psychology have argued that racism has taken on more covert forms. A longitudinal examination of newspaper coverage of two important race‐related newsprint stories in New Zealand (involving Winston Peters, Tuku Morgan and New Zealand First) identified discourses of ‘plausible deniability’ involved in warranting or defending statements about minorities against accusations of racism. We discuss implications of symbolic politics for minorities who are perceived to have violated societal norms, and show how nationalism is used as a framework for denying racist intent. Analyses of historical context show how ‘race’ forms only one lens from which to view issues of intergroup relations. While the press was sensitive to issues of racism, they demonstrated little awareness of concurrent issues of neo‐liberal economics, or market fundamentalism. Anti‐racism may be motivated not only by the ideals of egalitarianism, but also by underlying dynamics of economic power in a global economy. Copyright © 2006 John Wiley & Sons, Ltd.
