OBJECTIVE: To determine the mass scores of naringin and neohesperidin in Fructus aurantii and Citrus chang-shan-huyou with their processed products and evaluate the quality of Fructus aurantii and Citrus changshan-huyou with their pro-cessed products. METHODS:According to the requirements of Chinese Pharmacopoeia(2010 edition)and Zhejiang Province Tradi-tional Chinese Medicine Preparation Standards (2005 edition),the moisture and ash of F. aurantii and C. changshan-huyou with their processed products were detected. And the contents of naringin and neohesperidin were determined. The ZORBAX SB-C18 column was used with the mobile phase of acetonitrile-water(20∶80,V/V)at the flow rate of 1.0 ml/min. The detection wave-length was set at 283 nm,and the column temperature was 40℃.The samples size was 10μl. RESULTS:The moisture of F. au-rantii and C. changshan-huyou was decreased after processing with no obvious change for ash. The contents of naringin and neohes-peridin were decreased,significantly for F. aurantii,and all consistent with the requirements of Chinese Pharmacopoeia(2010 edi-tion)except F. aurantii. The linear range was 0.028 45-0.284 5μg(r=0.999 7)for naringin and 0.085 9-0.858 6μg(r=0.999 6)for neohesperidin;the RSDs of precision,stability and reproducibility tests were no more than 1.36% and the average recovery was re-spectively 96.45%-100.43%(RSD=1.45%,n=6) and 98.36%-102.00%(RSD=1.26%,n=6). CONCLUSIONS: There was no significant difference in the inspection and determination re-sults in F. aurantii and C. changshan-huyou. It is suggested to adjust the limitation of content determination in the Chinese Pharmacopoeia(2010 edition)and processed standards.

In December, the outbreak of a novel coronavirus (2019-nCoV) in Wuhan, China, has attracted extensive global attention. On January 20, 2020,the Chinese health authorities upgraded the coronavirus to a Class B infectious disease in the Law of the People's Republic of China on the Prevention and Treatment of Infectious Diseases, and considered it as Class A infectious diseases in disease control and prevention. On January 22, 2020, the 2019-nCoV nucleic acid detection test was listed as the diagnostic criteria in the "guidelines for diagnosis and treatment of pneumonia due to 2019-nCoV (Trial Version 2)" . Therefore, standardizing the operation process of the 2019-nCoV nucleic acid detection in clinical laboratories has become a top priority. It is of paramount importance to establish standard protocols for detection of the 2019-nCoV nucleic acids in clinical laboratories to improve the reliability of the results and ensure the biosafety of laboratory personnel.

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.
