Preparing for Practice: Strengthening Third-Year Medical Students’ Awareness of Point-of-Care Resources

This column describes the development and implementation of a responsive library course designed to train third-year medical students as they begin their clerkships. The course design consisted of a brief face-to-face introduction during third-year orientation and an online course developed in Canvas, an online learning management system. The objective of the course was to not only introduce students to the resources but also to teach them how to effectively use those resources at the point-of-care. Students evaluated the course to assess the overall effectiveness of the instruction. Course development and content, feedback provided by students, as well as suggestions for improvement are discussed.     

Medical interventions in the management of hamstring muscle injury

Abstract

Acute muscle belly injuries to the semitendinosus, semimembranosus and biceps femoris (the ‘hamstring’ muscles) remain a common problem in the sporting population. Physiotherapy-led rehabilitation remains the mainstay of treatment, and the physician's input is often minimal. Anecdotally, many different topical, oral and injectable therapies are used around the world in an effort to accelerate the healing of these injuries and to prevent their recurrence. This article reviews the evidence available to support some of the most commonly used medical therapies and the pathophysiological basis for their use. It also presents the evidence behind some of the more promising future treatments for muscle injury, including stem cell therapy, growth factor delivery and potential novel uses of current medication not traditionally used in the musculoskeletal setting.     

基于扎根理论的老年人中医药信息行为整体情境分析

[目的/意义]探索和分析老年人中医药信息行为相关的情境因素,为开展更高效的中医药信息服务提供理论支撑和依据。[方法/过程]主要采用质性研究中的扎根理论方法,于2017年3月至2018年6月,选取了22位老年人进行半结构深入访谈。针对访谈资料,采用三级编码方法,通过不断比较,对老年人中医药信息行为的情境进行深入分析。研究提出包含30个概念,8个次范畴,2个主范畴的老年人中医药信息行为情境相关概念体系。[结果/结论]老年人中医药信息行为的情境是由主体情境和主体条件共同构建的整体情境,两个情境组成要素相互区别又共同作用,推动、激发、调节着老年人的中医药信息行为。

论元极医学的医学模式

当今医学模式分为生物医学、生物－心理－社会医学、祖国传统中医药模式等。元极医学是在祖国传统中医药的基础上,吸取现代西方医学精华,以元极学独有的理论为指导,经实践检验而形成的一门新生的医学模式;它以西医、中医的理论为基础,又有自己独有的优势。元极医学模式的特点：对发病机理的认识,是从大自然对人体、社会环境的影响及人体自身的影响出发;其治疗疾病的基本物质是先天三元能量,治疗疾病的本质是从气化宇宙、光显     

临床医学专业“新生研讨课”实践与反思

“新生研讨课”是本科教育中新兴起的一种引导性的大学启蒙教育课程。山东大学在借鉴美国和国内“新生研讨课”开设经验的基础上,通过3轮教学实践,探索出适合临床医学专业“新生研讨课”的教学模式,这一模式有助于临床医学专业大学生完成由中学阶段向大学阶段的角色转换。     

Evaluation and application of an efficient plant DNA extraction protocol for laboratory and field testing

Nucleic acids in plant tissue lysates can be captured quickly by a cellulose filter paper and prepared for amplification after a quick purification.In this study,a published filter paper strip method was modified by sticking the filter paper on a polyvinyl chloride resin(PVC)sheet.This modified method is named EZ-D,for EASY DNA extraction.Compared with the original cetyl trimethylammonium bromide(CTAB)method,DNA extracted by EZ-D is more efficient in polymerase chain reaction(PCR)amplification due to the more stable performance of the EZ-D stick.The EZ-D method is also faster,easier,and cheaper.PCR analyses showed that DNA extracted from several types of plant tissues by EZ-D was appropriate for specific identification of biological samples.A regular PCR reaction can detect the EZ-D-extracted DNA template at concentration as low as 0.1 ng/μL.Evaluation of the EZ-D showed that DNA extracts could be successfully amplified by PCR reaction for DNA fragments up to 3000 bp in length and up to 80%in GC content.EZ-D was successfully used for DNA extraction from a variety of plant species and plant tissues.Moreover,when EZ-D was combined with the loop-mediated isothermal amplification(LAMP)method,DNA identification of biological samples could be achieved without the need for specialized equipment.As an optimized DNA purification method,EZ-D shows great advantages in application and can be used widely in laboratories where equipment is limited and rapid results are required.     

Bridging western and First Nations thought: Balanced education in Whitehead's philosophy of organism and the sacred circle

The sacred circle offers a perspective for interpreting and theorizing about human development valuable in shaping the education of First Nations and non-First Nations students. For those of us in a western materialist culture who are interested in coming to understand what the sacred circle might offer, it is necessary to address assumptions in our own culture. This paper proceeds in four parts to facilitate such an understanding. Part One formulates the importance of a culturally self-critical approach to understanding education based in the sacred circle. Part Two presents the sacred circle as a pattern used to interpret meaning in First Nations education. Part Three examinesinterconnectedness through (a) whitehead's criticism of western scientific epistemology and his idea of education for balanced development, and (b) through the creator, mother earth and the Four Directions reflected in the sacred circle. Part Four interprets aholistic apprehension approach to education based in (a) Whitehead's notion's of intuition and imagination for balanced development from the sacred circle perspective, and (b) through the sacred circle in the vision quest ceremony.     

Regulatory policy as innovation: Constructing rules of engagement for a technological zone of tissue engineering in the European Union

This paper addresses the question of the part that regulation plays in processes of innovation in sectors of technology. The politico-economic phenomenon of ‘Europe’ is partly constituted by regulatory regime-building, and new technologies are one of the major sites of regime-building. A constructionist social theory perspective shows that study of the conflictual processes of regulatory policymaking affords insights into the formation of the rules of engagement that constitute technology domains. Adopting the concept of emergent ‘technological zone’ in preference to industrial ‘sector’ or technoscientific network, the paper presents, using empirical research, a detailed account of the case of the debate and development of regulatory policy for therapeutic tissue engineering in the European Union's policy institutions and stakeholder networks. It describes how the jurisdiction of an emergent zone has been formed through such negotiations, providing a counter-example to the common view that regulation ‘lags behind’ innovation. The analysis takes account particularly of the part played by the malleability of the definition of the material technology itself in such constructive governance processes, and it also suggests various consequences for the array of producers of the technology, for market structuring and for the innovation pathways taken by tissue engineering technology. Concluding, the paper argues that there is conceptual advance to be made by bringing together constructionist social theory with innovation studies approaches that highlight the part played by non-firm, public institutions in shaping innovation ecologies.
