ABSTRACT
To investigate the research status and trends of application of objective structured clinical examination (OSCE) in medical education in China and globally, and to provide a reference for clinical teaching and medical education research. CNKI and Web of Science Core Collection were searched to identify journal articles related to OSCE published up to the present day. CtieSpace V software was used to visually analyze the research institutions, authors, highly cited literature, and keyword changes of the articles based on scientific knowledge maps. The overall number of publications on OSCE published in China and globally showed an increasing trend, but foreign publications were significantly more than Chinese publications. The institutions and authors were widely distributed. Comprehensive universities were the main institutions in foreign publications, with relatively little cooperation between each other. Domestic research primarily focused on medical education in the early stage, SP training and standardization in the middle stage, and clinical competence for resident physicians, nurses, and other clinical professionals in the late stage. Early foreign research focused mainly on medical education and clinical competence, while later research focused primarily on communication with patients and ability assessment. It is expected that future domestic research will focus on building clinical competence evaluation systems based on the OSCE model, while future foreign research will focus on patient communication and humanistic care assessment.

To explore the research hotspots and frontier directions of pyroptosis in the field of traditional Chinese medicine(TCM), the authors searched CNKI and Web of Science for literature related to pyroptosis in TCM, screened literature according to the search strategy and inclusion criteria, and analyzed the publication trend of the included literature. VOSviewer was used to draw author cooperation and keyword co-occurrence network diagrams, and CiteSpace was employed for keyword clustering, emergence, and timeline view. Finally, 507 Chinese literature and 464 English literature were included, and it was found that the number of Chinese and English literature was increasing rapidly year by year. The co-occurrence of the authors showed that in terms of Chinese literature, there was a representative research team composed of DU Guan-hua, WANG Shou-bao and FANG Lian-hua, and for English literature, the representative research team was composed of XIAO Xiao-he, BAI Zhao-fang and XU Guang. The network visualization of Chinese and English keywords revealed that inflammation, apoptosis, oxidative stress, autophagy, organ damage, fibrosis, atherosclerosis, and ischemia-reperfusion injury were the primary research diseases and pathological processes in TCM; berberine, resveratrol, puerarin, na-ringenin, astragaloside Ⅳ, and baicalin were the representative active ingredients; NLRP3/caspase-1/GSDMD, TLR4/NF-κB/NLRP3, and p38/MAPK signaling pathways were the main research pathways. Keyword clustering, emergence, and timeline analysis indicated that the pyroptosis research in TCM focused on the mechanism of TCM monomers and compounds intervening in diseases and pathological processes. Pyroptosis is a research hotspot in the area of TCM, and the current discussion mainly focuses on the mechanism of the therapeutic effect of TCM.

Background As emerging environmental contaminants with ecological risks, flame retardants (FRs) exhibit obvious toxicity and persistence. In recent years, as FRs have been widely detected in indoor environments and human samples, the human health risks after FRs exposure are of great concern. Objective To systematically understand the topic evolution, research status, progress, and development trends on the toxicity and health effects of FRs on humans worldwide. Methods We retrieved the literature regarding toxicity of FRs and their effects on human health through the Web of Science database from 2000 to 2020, screened and processed the literature using Endnote software, and analyzed annual publications, important citations, and authors. CiteSpace and VOSviewer were employed to draw co-citation network, keyword co-occurrence network, and keyword clustering map for bibliometric visualization analysis. Results From 2000 to 2020, 472 international papers on toxic effects and human health impacts of FRs were published. In terms of publication years, FRs-related research was mainly divided into three stages: the infancy and exploration stage (2001—2006), when the research on the toxic effects of FRs was just starting; the growth stage (2007—2015), when the risk assessments of FRs on human health were conducted; and the acceleration stage (2016—), when the studies have shifted to the mechanism of FRs damage to human health. In this field, China published the largest number of published articles in the world (177 papers), but the intermediary centrality (reflecting academic influence) was only 0.19, far lower than that of European and American countries such as the Netherlands (0.78), Britain (0.51), and Germany (0.44). Among the top 10 research institutions in terms of the number of articles published, the Chinese Academy of Sciences topped the list with 49 articles. Van der Veen and other researchers had a strong influence on the research of the toxic effects of phosphorous FRs since their papers published in 2012 were cited 1319 times and in the most prominent node in the literature co-citation network. The high-frequency keywords in the literature on the human health effects of FRs were polybrominated diphenyl ethers (217 times), brominated FRs (166 times), toxicity (147 times), FRs (102 times), exposure, polychlorinated biphenyls, in vitro experiment, plasticizer, etc. Through keyword clustering and co-occurrence analyses, it was found that current research is systematically exploring the toxic mechanism of FRs from a perspective integrating pollution source-exposure route-final receptor of pollutants, and is evaluating the environmental health risks via different exposure routes. The visualized bibliometric analysis findings suggested that future studies understand the underlying mechanisms of various cell damage caused by FRs toxicity, identify the key factors of change and their relationships, aiming to provide a scientific basis for targeted prevention of health effects of FRs. Conclusion The research hotspots on the toxic effects of FRs and their effects on human health have changed over time, and the breadth and depth have been increasing. The toxic effects of brominated/phosphorus FRs have always been the mainstream direction in this field. Further studies will focus on the molecular mechanisms of human toxicity after FRs exposure.

ABSTRACT
Objective To review the research progress, present the research status and analyze the evolution trend of hot spots through the bibliometric analysis of the research literature of cancer-related fatigue(CRF) at home and abroad. Methods We took CRF as the theme and the papers on CRF included in CNKI and WOS core database as the research object, and used VOSviewer and CiteSpace software as research tools, to make a visual atlas analysis on the research status and hot spot evolution at home and abroad. Results (1)Research status: ① Literature: 3 646 papers (1 959 in English and 1 687 in Chinese) were finally included. The number of papers published at home and abroad showed an overall upward trend, and the proportion of foreign fund papers was high; ② domestic papers focused on nursing and rehabilitation. The research area of foreign papers was more extensive, diverse and integrated; ③ Domestic cooperation was mainly small group cooperation, while foreign cooperation was more interdisciplinary and cross-team cooperation, forming a number of core teams and research institutions; ④ Domestic scholars paid attention to clinical application research and were good at learning from foreign countries and summarizing own experience. Foreign scholars paid more attention to basic research and the treatment was more systematic and standardized; ⑤ There were a variety of diagnostic and therapeutic evaluation tools, mainly foreign scales. (2) Hot spot evolution: "quality of life" had always been a common topic of concern at home and abroad. Domestic scholars focused on clinical research and emphasized "treatment based on examination of causes" and "treatment based on syndrome differentiation". Foreign scholars attached importance to basic research and methodological research, and advocated non-drug intervention such as sports. In recent years, complementary and alternative medicine had become a hot topic in the international research. Domestic scholars had paid more attention to the research of mechanism and methodology, and expanded the application of TCM characteristic therapy in CRF. Conclusion Integrated traditional Chinese and Western medicine and multi-disciplinary participation are the future diagnosis and treatment mode of CRF. It's the direction of future efforts to establish CRF evaluation and management mode with TCM characteristic non-drug therapy as the core under integrated medicine.

BACKGROUND: With the continuous development of three-dimensional (3D) printing technology and bone tissue engineering, more and more studies have applied 3D printing technology to bone tissue engineering, but the main research status, hot spots and development trend are not clear enough. OBJECTIVE: To explore the current research status, hotspots and development trends of this field through the literature metrology and visual analysis of research hotspots of 3D printing and bone tissue engineering. METHODS: The CNKI database was searched under the theme of “3D printing and bone tissue engineering research”. Based on the quantitative visual analysis method of CNKI literature, the author made a statistical analysis on the trend of the number of publications, publishing institutions and journals of the application of 3D printing technology in bone tissue engineering. VOSviewer software was used to analyze the author collaboration and keyword co-occurrence network of the literature, and the hot research topic was interpreted based on the literature. RESULTS AND CONCLUSION: (1) A total of 469 effective articles related to 3D printing and bone tissue engineering were retrieved. Since 2014, the research on 3D printing and bone tissue engineering has shown a steady growth trend. Chinese Journal of Tissue Engineering Research and Jilin University are the most published journal and institution in this field, respectively. The authors of the literature form five major groups, but there is very little cooperation between the groups. (2) Keywords co-occurrence network shows that the contents revealed by keywords commonly clustering into four research topics (bone tissue engineering scaffold material, 3D printing technology and its application in orthopedics, 3D printing and joint replacement, and others) and the top 10 keywords (3D printing technology, computer aided technology, bone tissue engineering, tissue engineering, fracture, bone defect, hydroxyapatite, three-dimensional, replacement, titanium alloy) really reflect the present situation and the hotspots of current 3D printing and the bone tissue engineering research, which can provide a reference for researchers in this field when choosing a research direction.

ABSTRACT
By searching the randomized controlled trials (RCTs) of acupuncture and moxibustion from CNKI since its inception date to december 31 of 2019, the development status and hot trend of RCTs of acupuncture and moxibustion in China were summarized. The CiteSpace and VOSviewer software were used to perform keyword co-occurrence analysis, clustering analysis, time-zone analysis and citation-burst analysis, and visual map was drawn. As a result, a total of 60 995 articles were included, which were published in 1027 academic journals with 1787 keywords. The publication date was from 1975 to 2019. During the past 45 years, the publications of RCTs on acupuncture and moxibustion had shown an overall growth trend with characteristics of the times. The RCTs of manual acupuncture ranked the top, and its proportion of publications every 5 years was stable in the past 30 years. Since 1994, the hot words such as electroacupuncture, warming needling, auricular point sticking and various acupoint therapies had emerged; meanwhile, the spectrum of diseases had broadened, and an evolutionary trend corresponding to therapies and disease systems had been formed. In recent decade, the RCTs using moxibustion therapy have increased significantly, and the hot words such as "sub-health" "winter diseases being treated in summer" and "acupoint application/ moxibustion during the dog days" had indicated that acupuncture clinical research was further inclined to the field of chronic disease prevention and health services, which was in line with social development and the needs of the times.

Objective To analyze the characteristics of papers published in Organ Transplantation in the past ten years. Methods The academic papers published in Organ Transplantation from January 2010 to December 2019 were retrieved from China National Knowledge Infrastructure (CNKI). The publication volume, the funded paper ratio, authors, research institutions and keywords were analyzed by information visualization software CiteSpace 5.3 and VOSviewer 1.6. Results From 2010 to 2019, a total of 919 academic papers were published in Organ Transplantation, with an average annual publication volume of 92, showing an overall stable trend. The funded paper ratio and the ratio of papers with funding support at the provincial level or above increased year by year, reaching 100% in 2019. High-yield authors mainly formed two research teams led by Shi Bingyi and Chen Guihua respectively. The first authors were distributed across China. In recent years, as many as 58 programmatic papers were published by national academic institutions, especially signed by Branch of Organ Transplantation of Chinese Medical Association. The average number of authors per paper was 4.94 in Organ Transplantation, and the proportion of papers contributed by two or more authors remained above 90% in recent years. According to the analysis of research institutions, the average number of institutions per paper was 1.60 in Organ Transplantation. Keyword co-occurrence network analysis demonstrated that liver transplantation, renal transplantation and organ transplantation were the research hotspots in the field of organ transplantation. Keyword cluster analysis showed that research mainly focused on 9 fields, such as liver transplantation, renal transplantation, organ transplantation, organ donation, posttransplantation complications, transplantation immunity, end-stage liver disease, xenotransplantation and stem cell transplantation. Keyword burst analysis showed that xenotransplantation, α-1, 3-galactose, transplantation immunity, apoptosis, donor specific antibody (DSA), antibody-mediated rejection (AMR) and flow cytometry were the research hotspots. Conclusions The authors that publish academic papers in Organ Transplantation come from major transplantation centers all over the country. The papers of Organ Transplantation cover the research hotspots of each branch in the field of organ transplantation, and include a large quantity of programmatic papers signed and published by national academic institutions, which show the frontier hotspots and the highest level of research in the field of organ transplantation in China, making Organ Transplantation an excellent academic journal.
