Background: Early exploration of the semi constrained “Floating-socket” total shoulder replacement (TsR) in 1974 led to a proliferation of various unconstrained designs that allowed resection or retention of the humeral head, depending upon the pathological process involved. Degenerative glenohumeral arthritis with mild to moderate involvement of subchondral bone allowed for a resurfacing option, while severe humeral head involvement required a partial or full humeral head replacement attached to an intramedullary stem for fixation. All components evolved from cemented to cementless application by 1982. The purpose of this paper is to describe the progression of Buechel-Pappas (B-P) shoulder replacement development from the early 1970’s in both cemented and cement less applications. Methods: Clinical evaluations of “Floating-socket” TsR, followed by B-P stem-type, resurfacing types, bipolar-type and revision components, all of which comprise the B-P shoulder Replacement system, were performed over a 49-year period. Results: “Floating-socket” implants improved the results of simple, constrained ball-in-socket designs, but generally failed by glenoid component loosening in both chimpanzee and human applications. Unconstrained resurfacing-type components, both anatomical humeral head and full proximal humeral components, were quite successful, with minimal failures observed in long-term studies. Bipolar salvage implants, used for severe proximal deficiencies, revisions and massive rotator cuff arthropathy, were also very successful;providing overhead range of motion in many patients. Conclusions: Resurfacing hemiarthroplasty, in patients with intact or repairable rotator cuff mechanisms, gave the most satisfactory results and were the least technically complicated to perform, requiring minimal instrumentation. Resurfacing of full proximal humeral deficiencies, using femoral resurfacing components, gave similar clinical results to more complex semi-constrained devices,

[目的/意义]古籍整理与出版是古籍保护的重要内容和方法之一,目前学界对古籍整理成果的法律保护还存在争议。[方法/过程]通过可视化分析软件Citespace对2000-2022年CNKI数据库中收录的我国古籍整理成果法律保护相关的130篇核心期刊论文进行统计分析,从发文数量、研究机构、核心作者、研究热点与前沿等方面,对近二十年我国古籍整理的法律保护研究成果进行梳理和总结。[结果/结论]结果表明:我国古籍整理成果法律保护研究的发文量呈波浪式增长趋势;高产机构主要由国家图书馆、天津师范大学古籍保护研究院构成,高校图书馆是研究的主要力量,但机构间合作不密切;核心作者共现网络密度低,合作程度有待提高;研究态势主要趋向于多学科交叉融合发展。在我国司法实践中,大多数法院认可古籍整理成果的独创性,符合著作权中作品的构成要件,少数法官则偏向于从民事权益的角度对其进行保护。而古籍整理成果的独创性在理论界成为争议焦点,部分学者提出了反不正当竞争法保护模式,但邻接权保护已渐成主流。从立法、司法、行政介入、合作研究四个方面,对完善我国古籍整理成果法律保护提出建议:加快古籍整理成果保护立法;完善司法实践中古籍整理成果的法律保护体系;利用行政手段加强古籍整理行业的监管力度;加强古籍整理成果保护研究机构的合作。

目的旨在对目前提供急性照护的医院识别认知障碍患者以及在病历中记录和管理认知相关信息的实际情况及政策要求和推荐方法进行综述。方法采用Whittemore和Knaf1的五步法,系统检索Medline,CINAHL和scopus数据库,并检索了灰色文献来源。纳人了提供急性照护的医院已实施的患者认知障碍识别和认知信息管理相关的文献。采用混合方法评价工具和灰色文献质量评估清单对文章质量进行评价。采用主题分析法呈现和整合结果。该综述已在PROsPERO预注册(CRD42022343577)。结果共22篇原始研究文献和10篇政府/行业文件被纳人分析。结果显示,实践和政策之间存在差距。尽管在政策层面上高度重视认知障碍的识别、认知相关信息的透明度,以及与患者、家属和照顾者(如适用)之间的互动,但有时在临床实践中,认知评估是非正式的,患者的认知相关信息未作记录,与患者、家属和照顾者的互动也存在不足。结论.通过整合认知评估,利用信息技术开发信息管理综合系统,建立相关法律法规,提供教育与和培训,并采用国家层面的策略,有可能显著改善对认知障碍患者的识别和护理。

Aims Adaptive evolution of invasive species is both particularly exciting for the evolutionary biologist and worrisome for those interested in controlling or halting *** species often have a dis-tinct timeline and well-recorded population *** invaders encounter new environments,they undergo rapid adaptive *** aim in this study was to measure variation of floral size in the invasive shrub Cytisus scoparius(scotch broom)and measure natural selection by pollinators on that *** research has found that this invasive plant is pollinator limited in Washington state and that declines in pollinator populations can contribute to local extinction in another invaded range(New Zealand).This plant is pollinated by both native and introduced species of bees,represent-ing a broad range of pollinator *** scoparius has a flower structure that is highly conducive to studies on pollinator choice,even in the absence of direct pollinator *** We surveyed urban and rural sites in and around the city of Olympia in Washington *** banner width,we were able to show that flower size varies substantially between plants but mini-mally within *** measuring the proportion of flowers that were‘tripped’,we could determine pollinator visitation rates and thus determine the level of selection due to pollinator choice *** Findings We found that *** is under natural selection by pollinators for increased flower ***,such positive natural selection was only seen in urban populations although it was consistent across two flowering *** populations of scotch broom do not appear to be under selection on flower *** natural selection by pollinators on broom flowers could result in adaptive evolution into a new pollination niche by an invading species.A higher level of variation in broom flowers seen here than seen in previous works in native regions suggests that *** may be high
