国家级预防医学实验教学示范中心的建设与展望

为满足当今社会对卫生防病人才的更高要求,更新传统的实验教学观念,构建全新的实验教学体系。教学内容以三基训练为基础,以培养学生的能力为重点,经过10年的建设与探索,总结出成功的经验。为适应我国公共卫生事业的发展,按照预防医学实验教学新体系和构筑宽口径实验教学平台的整体构思,在全国率先组建涵盖多学科的预防医学实验教学示范中心,对各学科开设的实验教学内容打破学科界限,有机整合,统筹安排,提高了学生的实验操作、设计和创新能力,中心建设的总体思路、运行机制得到了国内外40多所高校专家的认可。建立了涵盖多学科的实验教学示范中心;构建了新的实验教学体系;改革预防医学实验教学内容、方法、方式等,提高了学生的整体素质。中心十二五将在智能化、网络化的实验教学和实验室管理信息方面有突破。     

Directed collaboration patterns in funded teams: A perspective of knowledge flow

Collaborations in funded teams are essential for understanding funded research and funding policies, although of high interest, are still not fully understood. This study aims to investigate directed collaboration patterns from the perspective of the knowledge flow, which is measured based on the academic age. To this end, we proposed a project-based team identification approach, which gives particular attention to funded teams. The method is applicable to other funding systems. Based on identified scientific teams, we detected recurring and significant subgraph patterns, known as network motifs, and under-represented patterns, known as anti-motifs. We found commonly occurred motifs and anti-motifs are remarkably characterized by different structures matching certain functions in knowledge exchanges. Collaboration patterns represented by motifs favor hierarchical structures, supporting intensive interactions across academic generations. Anti-motifs are more likely to show chain-like structures, hindering potentially various knowledge activities, and are thus seldom found in real collaboration networks. These findings provide new insights into the understanding of funded collaborations and also the funding system. Meanwhile, our findings are helpful for researchers, the public and policymakers to gain knowledge on research(ers) evolution, particularly in terms of primordial collaboration patterns.     

危机抑或机遇:专利经营实体是非置辩

专利经营实体的兴起及其商业模式引起了国内外的广泛关注,其法律定性一直颇具争议.如何定性,不仅决定着专利经营实体的未来,而且关系着一国专利政策的走向.本文解读了专利经营实体的内涵,澄清了它与“专利怪物”的区别,详细梳理了肯定和否定专利经营实体商业模式的争执面相,并对此进行了评析.结合对以高智公司和中彩联为代表的专利经营实体的介绍,作者提出了我国在专利战略推进过程中应有的观念维度.     

通过多种形式组织专题提升科技期刊质量

[目的]探索医学期刊组织专题的有效途径,为国内医学期刊提供借鉴与参考。[方法]以《放射学实践》杂志为例,介绍其通过与协办单位合作、及时报道重大科研成果、围绕突发公共卫生事件等多种方式进行专题组稿的经验和体会;比较、分析专题论文和非专题论文的质量。[结果]《放射学实践》近3年成功组织了22个专题,极大地扩大了本刊在业内的影响。专题论文的篇均被引频次和篇均下载量均明显高于非专题论文。[结论]医学期刊编辑应该结合自身杂志特点,充分发挥积极性和主动性,勇于探索,敢于创新,不断开拓专题组稿的新方法和新形式,为提高期刊质量不懈努力。

Preparation and tribological performance of novel organotin compound as lubricant additive

Oil-soluble stannous naphthenate (SN) is synthesized by using naphthenatic acid and SnO. And its molecular structure is confirmed by IR and multielement oil analyzer (MOA). The tribological performances of the organotin as lubricant additive are evaluated with a four-ball friction and wear tester. These experiments indicate that the wear scar diameter (WSD) and friction coefficient are diminished while the load-carrying capability increased by comparison with that of base oil. The elemental composition of the boundary lubricating film is examined by means of Auger electron spectroscopy (AES). Synergistic effect is found in the load-carrying capability of the complex of SN and sulfured olefin. The analytical results of AES indicate that the good performance of stannous naphthenate is attributed to the formation of a boundary lubricating film containing Sn on the rubbed surface.

Stair climbing,genetic predisposition,and the risk of incident type 2 diabetes: A large population-based prospective cohort study

Background:Cross-sectional evidence and small-scale trials suggest positive effects of stair climbing on cardiometabolic disease and glucose regulation.However,few studies have examined the long-term association between stair climbing and the incidence of type 2 diabetes(T2D).We aimed to prospectively evaluate the association of stair climbing with T2D and assess modifications by genetic predisposition to T2D.Methods:We included 451,699 adults(mean age=56.3±8.1 years,mean±SD;55.2% females) witho...
