[Objective]. The aims of this article are to intuitively grasp the progress and hotspots in the field of research of gully erosion in the northeast of China black soil region, advance the development of research in gully erosion in the black soil region of northeast China. [Methods] 245 papers in CNKI and Web of Science databases were used to create a knowledge map of gully erosion in the black soil region of northeast using the bibliometric method and CiteSpace software. [Results] (1) Research on gully erosion in black soil area started late, and the number of published papers has increased significantly in the past 10 years, but the results published in international journals are few, accounting for only 26%. (2) The research institutions in this field mainly distribute in northeastern China, of which several institutions include Songliao Basin Committee of Ministry of Water Resources, Beijing Normal University, Northeast Institute of Geography and Agroecology of Chinese Academy of Sciences, Northeast Agricultural University, and Shenyang Agricultural University have made the outstanding contributions and shown the great influence in the field; Prof. Zhang Shuwen is the scholar with the most publications in Chinese, and Prof. Liu Baoyuan and Wu Yongqiu are the scholars with the most publications in English in this field. (3) The co-occurrence of keywords between the published literatures indicates that the current focus of attention on gully erosion in the black soil area of northeast China is mainly on the development characteristics, influencing factors and prevention and control measures of gully erosion. [Conclusion] The comprehensive research framework and a full understanding on gully erosion in the black soil region of northeastern China have not yet been established. In future research, there is a need to further emphasize the study of the formation and development processes and mechanisms of gully erosion in the black soil region of Northeastern China, and to conduct in-depth analyses of the influences of geological, topographical, hydrological, and human activities, among other factors.

Methods The last two period (from 2000 to the present) was divided into 3 stages based on representative genomic technologies, namely first-generation sequencing (2000—2007), whole-genome genotyping microarray (2008—2015), and next-generation sequencing (2016—now). All of the published literature (written in English) on cerebrovascular disease genetics and genomics were retrieved from core collection of Web of Science. Year of publication, country/area, and institution of the literature were summarized. VOSviewer 1.6.18 was used for statistical and visual analysis. The H-index was used to evaluate the quantity and the impact of the literature. Results A total of 8833 English literature was included in this analysis. The United States was the main contributor to the literature on stroke genetics and genomics, and published 3291 articles with an H-index of 182, both ranking first in the quantity and H index of papers. China published 1765 papers with an H-index of 66, ranking second in the quantity and tenth in H-index. The International Stroke Genetics Consortium (ISGC) was an important contributor in this field of stroke genetics and genomics. ISGC and its principal directors ranked among the top 20 authors in the number of publications. The hotspots gradually shifted from association analysis and meta-analysis in the early stage to Mendelian randomization in recent years. Conclusions In the field of stroke genetics and genomics, although our country started late, there is a trend of catching up in the total number of publications. Clinical and scientific researchers in China should strengthen domestic and international academic cooperation to further enhance the China’s influence in this field.

目的 以文献计量学为基础，应用CiteSpace软件对国内外卒中患者照顾者领域研究现状及热点问题进行分析，为深入开展该领域的研究提供参考。 方法 在中国知网和Web of Science数据库中检索从建库至2021年12月31日卒中患者照顾者领域的中英文文献，文献类型包括论著、综述、学位论文、会议论文。去除重复文献后，从发文量、作者、机构、国家、关键词等方面进行文献计量学分析。 结果 共纳入1298篇中文文献（中国知网），1763篇英文文献（Web of Science）。对于卒中患者照顾者的研究，中英文文献发表均整体呈逐年上升趋势，中国知网数据库中，发文量从2002年的4篇增至2021年的164篇；郑州大学张振香是发文量最多（48篇）的作者，郑州大学护理与健康学院（50篇）是该领域发文量最多的机构；除主题词外，“影响因素”“照顾能力”“照顾负担”“抑郁”“焦虑”“自我感受负担”等为高频关键词。在Web of Science数据库中，发文量从2009年的103篇增至2021年的201篇；美国发文量最多（565篇），约翰霍普金斯医学院的Roth在作者中发文量最多，Univ Toronto（55篇）在发文机构中居首位；“quality of life”“rehabilitation”“support”“burden”“care”“depression symptom”“survivor”等为高频关键词。 结论 国内外卒中患者照顾者领域的研究处于稳定发展阶段，发文作者、发文机构均呈现以高校和地域为中心的特点，但缺乏跨区域和跨单位合作；国内外研究热点不同，照顾负担及照顾能力的影响因素、卒中照顾者负性情绪为国内研究热点，照顾者生活质量的影响因素、照顾负担和抑郁症状、照顾者主导的康复对卒中患者的影响是国外研究热点。临床或科研工作者应加强各研究机构之间的合作，关注该领域的研究前沿和热点，提高研究深度和广度。 Abstract: Objective Based on bibliometrics, CiteSpace software was used to analyze the current research status and hot issues in the field of caregivers of stroke patients at home and abroad, to provide reference for further research in this field. Methods The relevant literature in the field of caregivers of stroke patients was retrieved from the China National Knowledge Network (CNKI) and Web of Science database from the database inception to December 31, 2021. The types of articles included clinical trials, reviews, dissertations and conference papers. Bibliometric analysis was conducted in terms of the number of papers, authors, institutions, countries and keywords. Results A total of 1298 Chinese and 1763 English literature were included. The number of these published articles is on the rise year by year both at home and abroad. In the database of CNKI, the number of published articles increased from 4 in 2002 to 164 in 2021. Zhang Zhenxiang of Zhengzhou University published the most (48 articles), and the Nursing and Health College of Zhengzhou University published the most (50 articles). In addition to the subject words, "influencing factors" "caring ability" "caring burden" "depression" "anxiety" and "self-perceived burden" were high-frequency keywords. In the Web of Science database, the number of published articles increased from 103 in 2009 to 201 in 2021, and the United States published the most (565 articles); Dr. ROTH D L of Johns Hopkins School of Medicine published the most; the Univ Toronto had the most publications (55 articles). "Quality of life" "rehabilitation" "support" "burden" "care" "depression symptom" and "survivor" were high-frequency keywords. Conclusion The research on caregivers of stroke patients at home and abroad was in a stable development stage in the recent ten years. The authors and institutions of these papers were all characterized by universities and regions, and lack of cross-regional and cross-unit cooperation. Domestic and foreign research hotspots were different. The influencing factors of caring burden and caring ability, and negative emotion of stroke caregivers were hot issues in China. The influencing factors of stroke caregivers' quality of life, caring burden and depressive symptoms of caregivers, and the influence of rehabilitation led by caregivers on stroke patients were hot issues abroad. The clinical and research workers should strengthen the cooperation among research institutions, pay attention to the research frontiers and hotspots, to improve the depth and breadth of research.

Methods The MR related English literature in the field of IS in the Web of Science Core Collection was retrieved up to September 2022. CiteSpace was used for cooperation network analysis among countries, institutions and authors, co-citation analysis of literature, co-occurrence and cluster analysis of keywords. Drug development of biomarkers casually linked to IS was inquired by the PharmSnap Global New Drug Database. Results A total of 200 articles were retrieved, and these studies entered a stage of rapid development in 2018. England had 80 articles, with intermediary centrality of 0.37 and 27 cooperation countries, while the US had 63 articles, with intermediary centrality of 0.10 and 21 cooperation countries or territories. All of the above data were in the top three of all countries or territories, making England and the US research centers in this area. China has published 106 articles, only with 16 cooperation countries or territories. Rainer Malik from Germany had published 20 papers, with 552 citation and 25 co-authors, all ranking the first. IL-6 was the only biological factor defined as a cluster label in the keywords clustering graph, and “inflammation” was the second most studied risk factor for IS in the keywords co-occurrence graph in the last three years. Among the 12 biomarkers of IS identified by MR, coagulation factor Ⅺ and lipoprotein (a) were the more promising drug targets and relevant drugs have entered clinical trials phase. Conclusions MR studies in the field of IS were carried out mainly in European countries or territories represented by England, the US and China. Inflammatory factors such as IL-6 were major research hotspots, and related studies provided evidence for biomarkers, such as coagulation factor Ⅺ and lipoprotein (a), as drug targets.
