基于Web of Science数据库对骨质疏松近十年文献计量分析

背景:在全球迈向老年化社会的今天,骨质疏松已成为威胁人类健康、严重影响老年人生活质量的主要疾病之一,骨质疏松症也是医学研究热点之一。目的:初步分析骨质疏松症的研究现状及最新进展,为该领域预防、临床和科学研究提供一定参考。方法:采用Web of Science数据库(简称WoS数据库)核心合集中子库SCI-EXPANDED(SCIE)为研究对象,根据引文分析法统计2009年至2018年近十年间以骨质疏松为主题相关文献,分析WoS数据库核心合集收录骨质疏松领域研究文献状况,包括文献发表出版年、机构、来源出版物、国家地区、研究方向、作者、基金资助等分布情况。结果:通过WoS数据库观察到骨质疏松领域近十年间国内外发表论文共40436篇,相关文献发表在117个国家的2946种期刊中,高产作者中英国的Cooper C发文量最多,与英国的Kanis JA及比利时的Boonen S为重要核心领军人物;科研机构均是大学研究机构,《国际骨质疏松杂志》、《骨与矿物研究杂志》、《骨骼》等业内期刊收录文献最多;研究方向中内分泌代谢与骨质疏松有相当密切关系;基金资助机构主要在国家基金机构或世界百强生物药企;高被引论文多发表在知名度很高的主流及顶尖期刊。结论:近十年我国骨质疏松类论文在该数据库发文量迅猛增长,位居第二位,但被引频次、篇均被引频次和h指数并不高,在论文研究深度与高产作者等方面还存在一定距离,说明总体研究实力还需进一步加强,有较大提升空间。

A Hospitalwide Integrated Database Infrastructure to Support a Research Program for a Multidisciplinary Breast Center

Abstract: The Revlon/UCLA Breast Center has started a multidisciplinary research program in order to explore all aspects of breast diseases and the care of women. Due to the many specialized fields in medicine, the data involved in research studies is likely to be managed by different organizations and by different computers. This sorely limits the ability to carry out studies that are concerned with the mass screening of very diverse types of data according to different patient conditions, treatment profiles, or both. To support its program, the Revlon/UCLA Breast Center has developed a research database that includes every breast patient and that is linked to the UCLA clinical hospital information system and radiology information system. Research data is collected using a Patient Intake Questionnaire that is completed by every patient before being archived in the Breast Center research database. We have developed a Database Integration System to allow the Breast Center research database to automatically acquire and integrate clinical data generated by consultations, treatments, procedures, and surgeries occurring at the UCLA Medical Center. The Database Integration System is based on a screen capture method and uses the generally available clinical application display programs. The system was rapidly and cost-effectively developed using commonly available computer tools. Moreover, it does not require any changes in the participating remote hospital computer systems. The Revlon/UCLA Breast Center database system is available to researchers through a simple graphical user interface. Complex research queries are conveniently handled using the advanced database Structured Query Language (SQL). Our integrated research/clinical database system is now operational and it gives the unique ability to research teams in several disciplines to rapidly search the whole patient population according to any patient profile, disease, or treatment condition defined by a study.?

A trajectory‐based sampling strategy for sequentially refined metamodel management of metamodel‐based dynamic optimization in mechatronics

Dynamic optimization problems based on computationally expensive models that embody the dynamics of a mechatronic system can result in prohibitively long optimization runs. When facing optimization problems with static models, reduction in the computational time and thus attaining convergence can be established by means of a metamodel placed within a metamodel management scheme. This paper proposes a metamodel management scheme with a dedicated sampling strategy when using computationally demanding dynamic models in a dynamic optimization problem context. The dedicated sampling strategy enables to attain dynamically feasible solutions where the metamodel is locally refined during the optimization process upon satisfying a feasibility‐based stopping condition. The samples are distributed along the iterate trajectories of the sequential direct dynamic optimization procedure. Algorithmic implementation of the trajectory‐based metamodel management is detailed and applied on two case studies involving dynamic optimization problems. These numerical experiments illustrate the benefits of the presented scheme and its sampling strategy on the convergence properties. It is shown that the acceleration of the solution time of the dynamic optimization problem can be achieved when evaluating the metamodel that is lower than 90% compared to the computationally expensive model.
