艾灸治疗失眠的临床应用规律分析＊

目的 回顾1959年至2018年发表的灸法治疗失眠的临床文献，总结归纳灸法治疗失眠的临床应用规律。方法 检索《中国针灸信息库》、中国期刊全文数据库（清华同方）、万方数字化期刊（万方）、中文科技期刊全文数据库（维普），按照纳入和排除标准筛选灸法治疗失眠的临床研究文献，进行计量分析、聚类分析和关联性分析。结果 艾灸治疗失眠应用频次较高的穴位依次为百会、三阴交、神门、足三里；足太阳膀胱经穴应用频次最高，其次是督脉穴和肾经穴。下肢部的腧穴使用频次最高，其次为头面部、背部。关联性较高的穴对为内关、足三里、神门、百会和三阴交，关联性较高的治疗方法为艾条灸配合针刺。灸法配合中药的总有效率最高，其次为灸法配合针刺，疗效均优于单纯灸法（均P < 0.05）。对比灸法、灸药并用、灸刺并用疗法治疗前后的PSQI评分，灸法与灸药并用疗法比较差异有统计学意义（P < 0.05），与灸刺并用比较差异无统计学意义（P > 0.05）。结论 灸法治疗失眠的组方中主要穴对为内关、足三里、神门、百会和三阴交。配合疗法中灸刺结合的使用频率最高，但灸法配合中药疗法的有效率最高，对于PSQI评分的改善程度亦最大。     

Bibliometric analysis of orthopaedic related publications by Indian authors from the last decade

PurposeBibliometric studies have been established methods of analysing publications on a particular topic. These studies have been done on various orthopaedic topics and are increasing. The advantages of these studies have been highlighted in previous publications. Although some studies have been done on Indian publications from other specialties, those analysing Indian Orthopaedic Publications are lacking.MethodsWe performed a search in Scopus to look for all publications related to orthopaedics from India. Our search strategy in Scopus included ((TITLE-ABS-KEY(Orthopaedics OR Orthopaedics) AND AFFIL(India)) AND PUBYEAR > 2009 AND PUBYEAR < 2020) which resulted in 3270 articles on 02/11/2021. We analyzed the most publishing universities, city, state, specialty, authors, and anatomic location of these publications. We also mined the data to draw word clouds based on data obtained from the titles of articles, keywords and the affiliations of each of the articles published.ResultsTamil Nadu and New Delhi and their institutes appear to be the epicenter of publication activities in Orthopaedics in India. There has been a healthy trend of growth of articles in the orthopaedic specialty. Since there is a significant overlap of technology and engineering, it is not surprising to see engineering and technology institutes among the top 10 published institutes and even journals for the publications on orthopaedics.ConclusionThere has been a steady increase in the number of publications in the last decade. New Delhi and its Universities and Institutes appear to contribute the majority of citations and publications related to orthopaedics. Journal of Clinical Orthopaedics and Trauma was the most publishing journal for Indian authors on Orthopaedic related articles.     

Bibliometric analysis of the 100 most-cited articles in the field of hepatology

ObjectiveBibliometric search of citation classics can function as a tool to identify extraordinary landmark articles and advanced research studies. We aimed to examine and characterize the 100 most-cited published articles in the field of hepatology.Patients and methodsA comprehensive list of the 100 most-cited articles published from 1950 to 2017 in the field of hepatology was compiled after searching the Web of Science with relevant terms, including “liver,” “hepatitis,” “hepatic,” “hepatocellular,” “hepatology,” “cirrhosis,” and “steatohepatitis.” The articles were ranked according to their citation counts and were evaluated for characteristics including country, institution, authorship, publication year, subspecialty and others.ResultsThe database search returned 323,291 articles associated with liver disease published between 1950 and 2017. The 100 most-cited articles were from 21 major journals, with the highest number of articles being published in Hepatology (n = 20). The average number of citations of the 100 most-cited articles was 1946.8; among these articles, the most frequently cited article received 5515 citations, and the least frequently cited article received 1155 citations. In total, 60 were original articles among the 100 most-cited articles. The most frequently represented specialties were hepatitis, hepatocellular carcinoma, and nonalcoholic fatty liver disease, which accounted for 53.3%, 23.3%, and 11.7% of these articles, respectively.DiscussionOur study identified citation classics and provided a review of the most advanced studies in the field of hepatology. This can help to guide clinical treatment and future academic research resulting in advancements in hepatology.     

近10年中医药治疗糖尿病前期的文献计量分析

糖尿病是严重威胁人类健康的疾病,早期干预可以延缓其发生发展。近年来,中医药治疗糖尿病前期受到越来越多的关注。我们分析中医药治疗糖尿病前期领域的研究现状,并根据目前的研究热点预测未来的发展趋势,为以后的研究方向提供参考依据。我们以Cochrane library、Pubmed、Embase、中国知网、维普数据库、万方数据知识服务平台、生物医学文献数据库(CBM)为检索对象,检索关于中医药治疗糖尿病前期的文献,并对其进行文献计量学分析。我们利用文献管理软件Note Express对符合纳入标准的210篇文献进行统计分析。从文献的年代分布、期刊分布、作者分布、作者所在单位分布、文献类型分布、所涉及的干预方法的分布及文献的高频关键词分布等方面,初步探讨中医药治疗糖尿病前期的研究现状、热点和趋势。将文献计量学方法运用于中医文献的分析对临床和科研工作的具有重要指导作用。     

Top-cited articles in endodontic journals

Introduction

The purpose of this study was to identify the 100 top-cited articles published in journals dedicated to endodontology and analyze their characteristics to describe the quality and evolution of research in the field of endodontology.

Methods

The Institute for Scientific Information Web of Knowledge Database and the Journal Citation Report Science Editions were used to retrieve the 100 most cited articles published in journals dedicated to endodontics. The top-cited articles were selected and analyzed with regard to journals, authors, institution, country of origin, publication title and year, number of citations, article type, study design, level of evidence, and field of study.

Results

The top 100 articles were cited between 87 and 554 times. These articles appeared in 4 different journals, with more than half in the Journal of Endodontics, followed by the journals Oral Surgery Oral Medicine Oral Pathology Oral Radiology and Endodontology, the International Endodontic Journal, and Endodontics & Dental Traumatology. Forty-eight articles were published between 1990 and 1999. All articles were published in English and primarily originated from the United States (n = 52). The majority of articles were basic science articles (n = 55), followed by clinical research studies (n = 28) and nonsystematic reviews (n = 17). Uncontrolled case series with level IV of evidence and narrative reviews with level V of evidence were the most frequent types of study design. The main topics covered by the top-cited articles were microleakage and endodontic microbiology.

Conclusions

This analysis of citation rates reveals useful and interesting information about scientific progress in the field of endodontics. Basic research and observational studies published in high-impact endodontic journals had the highest citation rates.     

A longitudinal analysis of bibliometric and impact factor trends among the core international journals of nursing, 1977–2008

Background

Although bibliometric analysis affords significant insight into the progression and distribution of information within a particular research field, detailed longitudinal studies of this type are rare within the field of nursing.

Objectives

This study aimed to investigate, from a bibliometric perspective, the progression and trends of core international nursing journals over the longest possible time period.

Methods

A detailed bibliometric analysis was undertaken among 7 core international nursing periodicals using custom historical data sourced from the Thomson Reuters Journal Citation Reports^®.

Results

In the 32 years between 1977 and 2008, the number of citations received by these 7 journals increased over 700%. A sustained and statistically significant (p < 0.001) 3-fold increase was also observed in the average impact factor score during this period. Statistical analysis revealed that all periodicals experienced significant (p < 0.001) improvements in their impact factors over time, with gains ranging from approximately 2- to 78-fold.

Conclusions

Overall, this study provides one of the most comprehensive, longitudinal bibliometric analyses ever conducted in the field of nursing. Impressive and continual impact factor gains suggest that published nursing research is being increasingly seen, heard and cited in the international academic community.
