A comparative study of international and Chinese public health emergency management from the perspective of knowledge domains mapping

BACKGROUND@#At the end of 2019, the outbreak of coronavirus disease 2019 (COVID-19) severely damaged and endangered people's lives. The public health emergency management system in China has played an essential role in handling the response to the outbreak, which has been appreciated by the World Health Organization and some countries. Hence, it is necessary to conduct an overall analysis of the development of the health emergency management system in China. This can provide a reference for scholars to aid in understanding the current situation and to reveal new research topics.@*METHODS@#We collected 2247 international articles from the Web of Science database and 959 Chinese articles from the China National Knowledge Infrastructure database. Bibliometric and mapping knowledge domain analysis methods were used in this study for temporal distribution analysis, cooperation network analysis, and co-word network analysis.@*RESULTS@#The first international article in this field was published in 1991, while the first Chinese article was published in 2005. The research institutions producing these studies mainly existed in universities and health organizations. Developed countries and European countries published the most articles overall, while eastern China published the most articles within China. There were 52 burst words for international articles published from 1999-2018 and 18 burst words for Chinese articles published from 2003-2018. International top-ranked articles according to the number of citations appeared in 2005, 2007, 2009, 2014, 2015, and 2016, while the corresponding Chinese articles appeared in 2003, 2004, 2009, and 2011.@*CONCLUSIONS@#There are differences in the regional and economic distribution of international and Chinese cooperation networks. International research is often related to timely issues mainly by focusing on emergency preparedness and monitoring of public health events, while China has focused on public health emergencies and their disposition. International research began on terrorism and bioterrorism, followed by disaster planning and emergency preparedness, epidemics, and infectious diseases. China considered severe acute respiratory syndrome as the starting research background and the legal system construction as the research starting point, which was followed by the mechanism, structure, system, and training abroad for public health emergency management.

A study of the anatomical delamination of posterior renal fascia by CT / 实用放射学杂志

Objective To study the features of anatomical delamination of the posterior renal fascia in CT images.Methods Clinical datas and CT images of 85 patients with acute pancreatitis were collected,the anatomical delamination features of the adult posterior renal fascia were observed and recorded.Results (1) 23 cases showed anatomical delamination of the left posterior renal fascia, 9 cases showed anatomical delamination of the right posterior renal fascia, and 8 cases showed anatomical delamination of bilateral posterior renal fascia.(2) The features of anatomical delamination of the posterior renal fascia were detected in the whole posterior renal fascia or in the lateral part of the posterior renal fascia.Anatomical delamination was detected in the whole left posterior renal fascia in 6 cases, and was detected in the lateral part of the left posterior renal fascia in 17 cases.Anatomical delamination was detected in the whole right posterior renal fascia in 4 cases and in the lateral part of the right posterior renal fascia in 5 cases.Anatomical delamination of the whole part in the bilateral posterior renal fascia were detected in 4 cases and pure delamination of the lateral part in the both sides were 4 cases.Conclusion CT images can show the anatomical delamination of the posterior renal fascia which has two types.The anatomical delamination of bilateral posterior renal fascia is not always the same.

Propensity score matching-based therapeutic effect evaluation in patients with hepatocellular carcinoma / 南方医科大学学报

<p><b>OBJECTIVE</b>To evaluate the therapeutic effects of transcatheter arterial chemoembolization (TACE) with or without radiofrequency ablation (RFA) in hepatocellular carcinoma (HCC) patients based on propensity score matching.</p><p><b>METHODS</b>A logistic regression model was established with the treatment assignment as the dependent variable and the covariates as the independent variables. For each HCC patient, the propensity score was calculated from the model for caliper matching, and a survival analysis of the matched data were carried out.</p><p><b>RESULTS</b>The covariates between the groups were balanced after caliper matching based on the propensity scores. Before matching, the one-, two-, and three-year survival rates of TACE and TACE+RFA were 52.07% and 59.08%, 32.24% and 36.43%, and 316.54% and 19.39%, with the median survival time of 1.20 and 1.40 years, respectively, showing no significant differences in the overall survival rate between the two groups. After matching, the 1-year, 2-year, and 3-year survival rates of TACE and TACE+RFA groups were 54.39% and 62.28%, 23.15% and 40.08%, and 10.20% and 18.52%, with the median survival time of 1.10 years and 1.50 years, respectively, showing significant differences in the overall survival between the two groups. The survival rate in TACE+RFA group was higher than that of TACE only group.</p><p><b>CONCLUSION</b>Propensity score matching can effectively reduce the confounding bias of non-randomized clinical observational data for a more accurate evaluation of the therapeutic effect in HCC patients.</p>
