微创技术在脑血管病诊治中的应用与存在的问题

脑血管病是危害人类健康的三大疾病之一.随着CT、,MRI、DSA等先进设备的应用,脑血管病的诊治水平进入一个新的阶段.显微手术、血管内栓塞、γ-刀或X-刀等很多微创技术不断应用于脑血管病的治疗.由于各地区发展不平衡,微创技术的应用尚存在不少问题.因此,必须积极稳妥地开展脑血管病诊治中的微创技术.     

微创人文思想的创立和实践

创立与医学相关的人文思想即微创人文思想,其不是杜撰出来的,自从有了人类、自从有了目的在于治疗疾病的医生这个职业,医学这个学问,就有了这种人文思想.其具体实践应用还要做两件扎扎实实的工作.一是总结前人的想法、经验、教训及问题,给现在人以借鉴、学习,二是提出新的问题供大家研究、探讨、总结、宣传,以发展微创人文思想.     

微创体系中人文思想的探索

医学人文学是发展现代医学的一项重要内容.从微创医学体系中的人文思想、探索微创人文思想的意义、实现微创医学过程中的微创人文思想三个方面对建立在现代医学模式基础上的微创医学体系发展中的有关人文思想进行了系统的探索,以揭示微创医学体系中人文思想的意义和价值,同时强调其在医疗实践中的实际应用.     

Helping Children and Caregivers Cope with Repeated Invasive Procedures: How Are We Doing?

This paper discusses recent developments in the medical and psychological management of child behavioral distress during invasive (i.e., needle stick) procedures for diagnosis and treatment of chronic pediatric disorders. Along with a review of relevant studies from the medical, pediatric psychology and behavior analysis literatures, representative data are presented from recent research on pediatric procedural pain management. The impact of increasing use of implanted subcutaneous intravenous catheters (ports) and decreased reliance on intravenous cannulation is discussed. Similarly, the effects (and limitations) of more frequent use of topical anesthesia to prepare needle sites also are presented. The continuing need for adjunctive, nonpharmacological (i.e., cognitive and behavioral) interventions for procedural pain is emphasized, and recent studies on distraction and counter-conditioning-based treatments are described. Future research is encouraged on (1) behavioral interventions in relation to day-to-day contextual variables that modulate treatment effects and (2) the development of efficient screening measures to identify children and families who are least likely to cope effectively with repeated procedures, allowing them to be given greater priority for allocation of limited resources for psychosocial intervention.     

幽门螺杆菌诊断方法评价

诊断幽门螺杆菌（Hp）感染有侵入性和非侵入性两类方法。前者需通过胃镜取胃粘膜活检,包括快速尿素酶试验（RUT）、病理组织学检查、细菌培养及基因检测等;非侵入性方法包括尿素呼气试验（UBT）、血清Hp抗体测定及Hp粪便抗原检测等。各种检测方法的敏感性及特异性不一,适用范围也不同,选择合适的检测方法需结合Hp感染特点、检测条件及费用情况等。     

心血管疾病微创治疗的未来

心血管疾病的治疗正在经历从创伤到微创到预防的过程,实现微创的关键是如何适度、合理地使用技术,在循证医学评价系统的指导下,以人为本,以最小的创伤、最合理的成本达到最佳的疗效.达到微创医学的目的:为人类提供最人性、最科学、最先进、最规范和最全面的医疗保健服务,要求硬技术必须软着陆,需要政府的干预和政策的引导,需要社会的参与,需要学科重构.     

微创手术治疗肺癌面临问题的思考

作为一种新兴技术,微创外科手术治疗肺癌备受争议.运用唯物辩证法的基本原理,分析这种技术产生的背景、临床应用价值及发展前景,并与传统手术方法作了客观辨证的比较.认为微创外科治疗肺癌,在临床应用有其积极意义,值得肯定.     

How people familiarize themselves with complex ecological concepts—anchoring of social representations of invasive non‐native species

New terms and frameworks are constantly being incorporated into scientific and public discourses on the management of natural resources and the environment. The idea of invasive non‐native plant and animal species, i.e. of species that enter a new range and spread prolifically, is currently becoming part of the public discourse in Scotland. This constitutes a valuable opportunity to study how people engage with new scientific concepts. We analysed focus group and personal interview data to examine how participants (including the general public, conservation volunteers and scientists) familiarized themselves with the ecological concept of invasive non‐native species. Our analysis draws on the idea of anchoring in the formation of social representations, complemented by concepts from cognitive linguistics and conceptual blending, and defines anchoring as a process of information transfer from source to target domains. Our findings suggest that social representations of invasive non‐native species were constituted to a large degree by perceptions of species' detrimental impacts and the human role in and responsibility for the introduction process. By contrast, the non‐nativeness of a species was not relevant for participants from the general public and conservation volunteers. Three types of anchoring could be distinguished in our participants' discussions that differed with regard to the relations between source and target domain. Whereas participants from the general public and conservation volunteers used all three types of anchoring, scientists did not. The identification of different anchoring types also helped to explain incongruencies in the scientific discourse on invasive non‐native species, and has implications for public information campaigns.

Minimal Varieties of Involutive Residuated Lattices

We establish the existence uncountably many atoms in the subvariety lattice of the variety of involutive residuated lattices. The proof utilizes a construction used in the proof of the corresponding result for residuated lattices and is based on the fact that every residuated lattice with greatest element can be associated in a canonical way with an involutive residuated lattice.
