The purpose of this study was to explore the research hotspots and trends of Kinesio Taping in the last decade and provide new sights in future studies. Publications in the area of Kinesio Taping were searched from the Web of Science Core Collection database between 2011 and 2020. Citespace software was used to analyze data on countries/regions, institutions, authors, co-cited references, and keywords. A total of 677 publications were obtained in the last decade. We identified the most prolific countries, institutions, and authors in the field of Kinesio Taping from 2011 to 2020. The annual number of publications showed an upward trend. The most prolific country and institution were Turkey and Hacettepe University, respectively. The author with the biggest number of publications was Gul Baltaci from Turkey. The top 5 most frequent keywords were "pain", "tape", "strength", "exercise", and "reliability". The keywords with the highest centrality were "proprioception", followed by "reliability", "clinical trial", "ankle", and "pain". Ten clusters were found and the biggest one was "quadricep". The top 9 keywords with the strongest bursts were detected and "trial" had the highest burst strength. The results from the bibliometric analysis provide hotspots and trends in the field of Kinesio Taping. It is still in the development stage of the past decade. Pain relief, sports injury prevention and treatment, and proprioception enhancement to improve postural control were the hotspots from 2011 to 2020. High-quality trials and standardized criteria for applications are needed in the future.

Background: Heavy ion radiotherapy (HIRT) has great advantages as tumor radiotherapy. Methods: Based on 1,558 literatures from core collections of Web of Science from 1980 to 2020, this study visually analyzes the evolution of HIRT research, and sorts out the hotspots and trends of HIRT research using CiteSpace software. Results: Research on HIRT has received more extensive attention over the last 40 years. The development of HIRT is not only closely related to radiation and oncology, but also closely related to the development of human society. In terms of citation frequency, "International Journal of Radiation Oncology*Biology*Physics" was the top journal. In terms of influence, "Radiotherapy and Oncology" was the top journal. "Radiation therapy" and "carbon ion radiotherapy" were the two most frequently used keywords in this field. Conclusion: The evolution of the HIRT research has occurred in approximately three stages, including technological exploration, safety and effectiveness research and technological breakthroughs. Finally, some suggestions for future research are put forward.

In the recent years, migraine has been widely studied by scholars from all over the world. This study aimed to use scientometric methods to identify research frontiers and development trends in the field of migraine research. We used the Web of Science (WoS) core collection database to collect articles and reviews related to migraine published from 2010 to 2019 on March 25, 2020. VOSviewer, CiteSpace, and Excel were used for the scientometric analysis. A total of 6,357 publications (including 5,203 articles and 1,154 reviews) were identified. The United States published the most publications (n=2,151, 33.84%). Albert Einstein College of Medicine contributed the most publications ( n=220, 3.46%). Cephalalgia was found to be the core journal with the most publications (n=766, impact factor 2019 =4.868) as well as the most co-citations (n=35,535). Lipton RB authored the most publications (n=159, 2.50%), while Silberstein SD received the most co-citations (n=4,215). The critical topics were causes and pathophysiological mechanisms, epidemiological characteristics, diagnostic criteria, treatment and prevention drugs, and migraine-related genes. Through the use of scientometric methods, this article has mapped the knowledge landscape of migraine research over the past decade. By showing the overall status of the field, it provides a useful reference for future research.

Background Traditional Chinese medicine (TCM) has been widely accepted and applied worldwide, and many publications related to Angelica sinensis (Oliv.) Diels (AS, Chinese name is "Danggui") have been published. However, to date, there has not been a scientometric study to systematically analyze the intellectual landscape and emerging research trends regarding AS. Therefore, we performed a scientometric study to address this gap. Methods Publications related to AS published from 2009 to 2018 were identified and selected from the Web of Science (WoS) Core Collection on May 30, 2019 using relevant keywords. HistCite, CiteSpace, and Excel 2016 software tools were used to conduct this scientometric study. Results Seven hundred and sixty-seven articles (including 717 primary articles and 60 review articles) and their cited references were included and analyzed. The majority of publications (N = 565, 73.7%) were published in mainland China, with Nanjing University of Chinese Medicine contributing the most publications (N = 42, 5.5%). The first core journal was Journal of Ethnopharmacology (N = 58, 7.6%; impact factor = 3.414). The identification and assessment of active components (like ferulic acid) of AS and their pharmacological actions (such as immunomodulatory effects) are the current research foci for AS research. Conclusion The present scientometric study provides an overview of the development of AS research over the previous decade using quantitative and qualitative methods, and this overview can provide references for researchers focusing on AS.

Background: To systematically analyze the global development trends and research focuses of shared decision-making (SDM) studies as a reference for researchers. Methods: We conducted a systematic search of the Web of Science (WoS) Core Collection on April 17, 2019, to retrieve studies related to SDM published from 2009 to 2018. VOSviewer (1.6.10), CiteSpace (5.4.R1) and Excel 2016 were used to analyze key features of SDM studies, including annual output, countries/regions, organizations, journals, authors, references, research hot-spots, and frontiers. Results: Up to April 17, 2019, a total of 6,629 studies on SDM were identified as published between 2009 and 2018. The United States participated in the most studies (n = 3,118), with the University of California-San Francisco ranking first (n = 183). Patient Education and Counseling [impact factor (IF) 2017 = 2.785] published the most studies (n = 257). Legare F participated in the most studies (n = 101), and the paper "Charles C, 1997, Soc Sci Med, V44, P681" occupied the highest co-citation (n = 657) position. The research hotspots and frontiers included "Informed consent," "Surgery," "Depression," "Older adult," and "Patient-centered care." Conclusion: The number of studies concerning SDM has continued to increase since 2009, with the United States leading the field. The landscape of the basis of SDM included mainly concept, practice framework and effect assessment of SDM. "Informed consent," "Surgery," "Depression," "Older adult," and "Patient-centered care" reflected the latest research focuses, and should receive more attention.

Electronic waste (e-waste) has been widely studied by scholars all over the world, but the research topics and development trends in this field are still unclear. This study aimed to explore the status quo, hot topics, and future prospects in the field of e-waste. Data of publications were downloaded from the Web of Science Core Collection. We used CiteSpace V, Histcite, and VOSviewer to analyze literature information. A total of 2800 papers in e-waste research were identified, and the number of publications increased rapidly after 2004. Six thousand five hundred seventy-three authors participated in the e-waste research, but 70.01% of the authors published only 1 article. The most productive country in this field was China (1146 publications), and the most productive institution was the Chinese Academy of Sciences (370 publications). The Waste Management (225 publications) was the most productive journal, and Environment Science & Technology (9704 co-citations) was the most co-cited journal. The main hot topics in e-waste field were management and recycling of e-waste in developing countries, health risk assessment after exposure to organic pollutants, degradation and recovery of waste metal materials, and impact of heavy metals on children's health. The frontier topic was degradation.
