    没有进行系统分析或审查来澄清术语历史和关于Chiari畸形(CM)的术语滥用的主题。我们审查了所有为CM创造的合理使用术语的报告,并提供了它们的词源和未来发展。检索了有关CM命名法的所有文献,并将其提取到核心术语中。随后,关键词分析,预测和预测(2023-2025年)每个核心术语的复合年增长率(CAGR),在Python中使用数学公式和自回归积分移动平均模型进行计算。确定了总共64,527厘米的术语用法。其中,收集57个原始术语,然后提取成24个核心术语。十七个术语有自己的特色作者关键字,而七个术语是同源的。上述24个术语的复合年增长率显示,18个术语的使用显着增长,13,3,三,五个任期可能显示出持续增长,保持稳定,下降,很少使用,分别,在未来。以前,由于复杂的命名法,Chiari术语经常被滥用,出现了许多看似新颖但毫无价值的甚至不恰当的术语。对于由多种病因引起的非常基本的神经病理学现象,一个基于机制的nosology似乎更有利于未来的沟通比一个伞形的同义词。然而,一个好的命名法也应该囊括这种情况的所有特征,但这在目前的CM研究中是缺乏的,由于大多数CM的病理生理机制尚未阐明。
    There is an absent systematic analysis or review that has been conducted to clarify the topic of nomenclature history and terms misuse about Chiari malformations (CMs). We reviewed all reports on terms coined for CMs for rational use and provided their etymology and future development. All literature on the nomenclature of CMs was retrieved and extracted into core terms. Subsequently, keyword analysis, preceding and predicting (2023-2025) compound annual growth rate (CAGR) of each core term, was calculated using a mathematical formula and autoregressive integrated moving average model in Python. Totally 64,527 CM term usage was identified. Of these, 57 original terms were collected and then extracted into 24 core-terms. Seventeen terms have their own featured author keywords, while seven terms are homologous. The preceding CAGR of 24 terms showed significant growth in use for 18 terms, while 13, three, three, and five terms may show sustained growth, remain stable, decline, and rare in usage, respectively, in the future. Previously, owing to intricate nomenclature, Chiari terms were frequently misused, and numerous seemingly novel but worthless even improper terms have emerged. For a very basic neuropathological phenomenon tonsillar herniation by multiple etiology, a mechanism-based nosology seems to be more conducive to future communication than an umbrella eponym. However, a good nomenclature also should encapsulate all characteristics of this condition, but this is lacking in current CM research, as the pathophysiological mechanisms are not elucidated for the majority of CMs.

    以前对图书馆和信息科学文献趋势的调查显示,随着时间的推移,图书馆员发表的主题发生了变化。较早的研究强调分类和索引,和信息检索,以及最近的研究强调互联网等关键词,信息技术,数字图书馆,再一次,信息检索。健康科学图书馆员没有对当前的出版趋势进行过类似的调查。这项研究通过检查关键字的频率,分析了健康科学图书馆员从2016年到2020年发布的主要主题。关键词和主题词来自《医学图书馆协会杂志》,医疗参考服务季刊,医院图书馆学杂志,和医学图书馆电子资源杂志。总共下载了8,806个关键字进行分析,并在分类法创建过程中分为292个类别。最常见的十个主题是:图书馆,信息,教育,人类,人口统计学,图书管理员,地理位置,研究,电子资源,和技术。研究还发现,数据,精神病学和心理学,信息学,出版是其他关键主题,这表明健康科学图书馆员正在发表广泛的主题。一些只出现过一次的关键词,例如远程办公和灵活的人员配置,为图书馆员提出新兴的研究领域。
    Previous investigations into trends in Library and Information Science literature have revealed changes in the topics librarians publish on over time, with older studies highlighting classification and indexing, and information retrieval and more recent studies highlighting keywords such as Internet, information technology, digital libraries, and again, information retrieval. No similar investigation has been conducted on current publication trends by health sciences librarians. This study analyzes the top themes on which health sciences librarians published from 2016 to 2020 by examining the frequency of keywords. Keywords and subject headings were analyzed from The Journal of the Medical Library Association, Medical References Services Quarterly, The Journal of Hospital Librarianship, and The Journal of Electronic Resources in Medical Libraries. A total of 8,806 keywords were downloaded for analysis and organized into 292 categories during taxonomy creation. The ten most frequent themes were: libraries, information, education, humans, demography, librarian, geographical locations, research, electronic resources, and technology. The study also found that data, psychiatry and psychology, informatics, and publishing were other key themes, indicating that health sciences librarians are publishing on a wide range of topics. Some keywords that appeared only once, such as telecommuting and flexible staffing, suggest emerging areas of research for librarians.

    抗生素耐药菌(ARB)严重威胁着人类健康和生态环境。随着这个问题变得越来越严重,更多的国家对ARB进行了研究,特别是在过去的十年中,研究数量急剧增加。因此,有必要在全球范围内回顾2010年至2020年发表的ARB的相关研究。这将有助于研究人员了解当前的研究状况,该领域的研究动态和研究热点。本文使用文献计量学来检查从WebofScience(WOS)检索的2010年至2020年ARB领域的出版物。我们的研究对这些国家进行了统计分析,机构,期刊,作者,研究领域,作者关键词,基础科学指标(ESI)被高度引用的论文,和ESI热点论文,提供ARB领域的概述以及研究趋势,研究热点,以及该领域未来的研究方向。结果表明,相关研究的数量逐年增加;美国在ARB领域发表最多;中国近年来在该领域最活跃;中国AcadSci发表的文章最多;Sci.总环境。发表的文章数量最多;CMManaia贡献最大;环境科学和生态学是最受欢迎的研究领域;以及“抗生素抗性,“\”抗生素,“”和“抗生素抗性基因”是最常见的作者关键词。引文分析表明,与水生环境相关的抗生素耐药性是该领域的重点研究领域,而与抗菌纳米材料相关的研究是最近的热门话题。
    Antibiotic-resistant bacteria (ARB) are a serious threat to the health of people and the ecological environment. With this problem becoming more and more serious, more countries made research on the ARB, and the research number has been sharply increased particularly over the past decade. Therefore, it is quite necessary to globally retrace relevant researches on the ARB published from 2010 to 2020. This will help researchers to understand the current research situation, research trends and research hotspots in this field. This paper uses bibliometrics to examine publications in the field of ARB from 2010 to 2020 that were retrieved from the Web of Science (WOS). Our study performed a statistical analysis of the countries, institutions, journals, authors, research areas, author keywords, Essential Science Indicators (ESI) highly cited papers, and ESI hotspots papers to provide an overview of the ARB field as well as research trends, research hotspots, and future research directions in the field. The results showed that the number of related studies is increasing year by year; the USA is most published in the field of ARB; China is the most active in this field in the recent years; the Chinese Acad Sci published the most articles; Sci. Total Environ. published the greatest number of articles; CM Manaia has the most contributions; Environmental Sciences and Ecology is the most popular research area; and \"antibiotic resistance,\" \"antibiotics,\" and \"antibiotic resistance genes\" were the most frequently occurring author keywords. A citation analysis showed that aquatic environment-related antibiotic resistance is a key research area in this field, while antimicrobial nanomaterial-related research is a recent popular topic.

    通过回顾科学文献,研究人员可以全面了解现场发展,了解当前的研究现状和热点转移。关键词的演变模式应该是揭示科学概念变化和可持续性配置的有效指标,想法,和研究热点。在这里,我们对1990年至2021年PNAS社会科学所有出版物中关键字的演变进行了广泛的调查。统计检验表明,关键字提及时间序列总是伴随着对数正态分布的出现。此外,我们介绍了一种新颖的四模式模式(TELS),它们是瞬态冲击类型,爆炸冲击类型,大冲击型,和小冲击型,分别,来说明关键词的演变。TELS模式可用于捕获任何建议关键字的整个生命周期特征,来自一群候选人。把整个时间分成四个周期,我们还引入了精英关键词的概念来揭示社会科学焦点的时间特征。从进化图中可以观察到从人类学研究到神经科学和社会问题研究的明确过渡。我们认为,所提出的方法具有一般意义,可能适用于其他科学领域。
    By reviewing scientific literature, researchers may obtain a comprehensive understanding of field developments, keeping abreast of the current research status and hotspot shifts. The evolution pattern of keywords is supposed to be an efficient indicator in revealing the shifting and sustainability configuration of scientific concepts, ideas, and research hotspots. Here we take an extensive investigation of the evolution of keywords among all publications in PNAS Social Sciences from 1990 to 2021. Statistical tests show the keyword mention time series always accompanied by the emergence of a log-normal distribution. Additionally, we introduce a novel schema of four patterns (TELS), which are Transient impact type, Explosive impact type, Large impact type, and Small impact type, respectively, to illustrate the evolution of keywords. The TELS schema can be used to capture the whole life circle feature of any proposed keyword, from a pool of candidates. By dividing the entire time into four periods, we also introduce the concept of elite keywords to reveal the temporal feature of social sciences focus. An explicit transition from anthropology research to neuroscience and social problems research can be observed from the evolution diagram. We argue that the proposed method is of general sense and might be applicable to other fields of science.

    背景:基因组学中的生物技术,如测序设备和基因定量软件,已经扩散并应用于临床环境。然而,缺乏适用于它的标准在互操作性和可重用性的技术在不同的应用程序领域提出了实际问题。本研究旨在可视化和确定临床基因组学的标准趋势,并提出标准化工作必须关注的领域。
    方法:在从PubMed检索到的16,538篇文章中,1975年至2020年出版,使用搜索关键词“基因组学和标准”和“临床基因组序列和标准”,术语摘自15855篇文章的摘要和标题。我们的分析包括(1)完整阶段的网络分析(2)五个阶段的周期分析;(3)统计分析;(4)内容分析。
    结果:我们的研究趋势显示出从2003年开始的增长趋势,这几年以人类基因组计划(2003年)的完成为标志。内容分析显示,与基因类型等概念相关的关键词进行分析,当美国FDA首次批准下一代测序仪时,在第3阶段增加了分析技术。在2017-2019年期间,肿瘤学相关术语被聚集,并导致内容分析第四阶段的增长趋势。在统计分析中,所有类别在整个分析期间均显示出较高的回归值(R2>0.586),基于相位的统计分析仅在遗传学术语类别(P=.039*)中在第4阶段显示出显著性.
    结论:通过我们研究的综合趋势分析,我们提供了临床遗传学标准化中的趋势变化和高需求项目.
    BACKGROUND: Biotechnology in genomics, such as sequencing devices and gene quantification software, has proliferated and been applied to clinical settings. However, the lack of standards applicable to it poses practical problems in interoperability and reusability of the technology across various application domains. This study aims to visualize and identify the standard trends in clinical genomics and to suggest areas on which standardization efforts must focus.
    METHODS: Of 16,538 articles retrieved from PubMed, published from 1975 to 2020, using search keywords \"genomics and standard\" and \"clinical genomic sequence and standard\", terms were extracted from the abstracts and titles of 15,855 articles. Our analysis includes (1) network analysis of full phases (2) period analysis with five phases; (3) statistical analysis; (4) content analysis.
    RESULTS: Our research trend showed an increasing trend from 2003, years marked by the completion of the human genome project (2003). The content analysis showed that keywords related to such concepts as gene types for analysis, and analysis techniques were increased in phase 3 when US-FDA first approved the next-generation sequencer. During 2017-2019, oncology-relevant terms were clustered and contributed to the increasing trend in phase 4 of the content analysis. In the statistical analysis, all the categories showed high regression values (R2 > 0.586) throughout the whole analysis period and phase-based statistical analysis showed significance only in the Genetics terminology category (P = .039*) at phase 4.
    CONCLUSIONS: Through comprehensive trend analysis from our study, we provided the trend shifts and high-demand items in standardization for clinical genetics.
