BACKGROUND:A pathophysiological feature of septic organ failure is endothelial dysfunction in sepsis(EDS).The physiological and pathological mechanism of sepsis is considered to be vascular leakage caused by endothelial dysfunction.These pathological changes lead to systemic organ injury.However,an analysis using bibliometric methods has not yet been conducted in the field of EDS.This study was conducted to provide an overview of knowledge structure and research trends in the field of EDS. METHODS:Based on previous research,a literature search was performed in the Web of Science Core Collection(WoSCC)for publications associated with EDS published between the year 2003 and 2023.Various types of data from the publications,such as citation frequency,authorship,keywords and highly cited articles,were extracted.The"Create Citation Report"feature in the WoSCC was employed to calculate the Hirsch index(h-index)and average citations per item(ACI)of authors,institutions,and countries.To conduct bibliometric and visualization analyses,three bibliometric tools were used,including R-bibliometrix,CiteSpace(co-citation analysis of references),and VOSviewer(co-authorship analysis of institutions,co-authorship analysis of authors,co-occurrence analysis of keywords). RESULTS:After excluding invalid records,the study finaly included 4,536 publications with 135,386 citations.Most of these publications originated in the USA,China,Germany,Canada,and Japan.Harvard University emerged as the most prolific institution,while professor Jong-Sup Bae and his research team at Kyungpook National University emerged as authors with the greatest influence.The"protein C","tissue factor","thrombin","glycocalyx","acute kidney injury","syndecan-1"and"biomarker"were identified as prominent areas of research.Future research may focus on molecular mechanisms(such as as vascular endothelial[VE]-cadherin regulation)and therapeutic interventions to enhance endothelial repair and function. CONCLUSION:Our findings show a growing interest in EDS research.Key areas for future research include signaling pathways,molecular mechanisms,endothelial repair,and interactions between endothelial cells and other cell types in sepsis.

Objective: To understand the characteristics of HIV/AIDS epidemic in Guangxi Zhuang Autonomous Region (Guangxi) with a purpose to accurately provide scientific basis for prevention and control measures, 2010-2017. Methods: Data were retrieved from case reporting cards of Guangxi during 2010 to 2017 through National HIV/AIDS Comprehensive Response Information Management System. Data was analyzed using epidemiological methods such number of cases, proportion and rate. χ² test was used for statistical analysis. Results: The HIV positive rate was 12.53 per ten thousand (85 182/67 959 000) in Guangxi during 2010 to 2017. The number of newly diagnosed HIV/AIDS cases and the number of death yearly respectively increased by 22.34%(2 602/11 648) and 32.83% (952/2 900) in 2011 compared with 2010, and both showed a six-year continuous downward trend (the number of newly diagnosed cases respectively 12 229 cases, 10 877 cases, 9 460 cases, 9 190 cases, 8 848 cases, 8 680 cases, and the number of death respectively 3 888 cases, 3 316 cases, 2 914 cases, 2 717 cases, 2 595 cases, 2 600 cases) from 2012 to 2017. But proportion of late discovery remained above 50.00% (50.53%-57.06%) for eight-years continuously. The ratio of male and female was 2.47 ∶ 1 (60 639/24 543). The ratio of males and females aged 50 and over was 2.71∶1 (28 654/10 557). Proportion of the cases in 25-49 years old group and 50 years old group accounting for 47.40%(40 377/85 182) and 46.03% (39 211/85 182) respectively. The occupation was farmers accounting for 68.40% (58 262/85 182), housekeeping, housework and unemployment accounting for 11.21% (9 546/85 182), student accounting for 0.86% (729/85 182). Heterosexual transmission accounted for 90.60% (77 171/85 182, homosexual transmission accounted for 3.13% (2 669/85 182), injection drug use transmission accounted for 4.60%(3 924/85 182) and mother-to-child transmission accounted for 0.73% (619/85 182). Conclusions The number of newly diagnosed cases and the number of death yearly showed a continuous downtrend for six-years from 2012 to 2017. However, proportion of late discovery remained above 50.00% for eight-years. The major route of infection was heterosexual transmission. With the change of HIV/AIDS newly epidemic mode in Guangxi, there are many new challenges for HIV/AIDS prevention and control work. Strategy of targeted intervention modes should be innovated for a new breakthrough.
