Objective To investigate the risk factors in children with hand-foot-mouth disease(HFMD)hospitalized after the second visit to outpatient department(OPD),and to evaluate their predictive value.Method In May 2008,180 of 343 pediatric patients with HFMD were repatriated to family or community after preliminary diagnosis in Bering Ditan Hospital.The ill children hospitalized after revisit(RVH)were compared with the remaining children(control group)for seeking the differences in age,HFMD contagion,temperattLre,interval between onset and visit,WBC count,skin lesion and comphcating risk symptoms by respective analysis.Logistic regression analysis was performed to find the risk factors involved in patients with RVH and diagnostic evaluation was introducted to predict the probability of RVH.Results Of 180 ill children,17(9.44%)ones returned to family or community requested admission into hospital for further consultation because who symptoms urtremitted or complications developed.The average duration between the preliminary visit and second visit was 3.26 days(0.5~14 days).No significant differences were found between RVH group and control group in age(P=0.669),ratio of gender(P=0.101),conttagion with HFMD(P=0.104),and typing of vires(P=0.475).Compared with control groups,the significant prolongation of interval between onset and visist(3.71±1.10)d,significant eleva-tion of temperature(38.74±0.57)℃ and WBC counls(10.99±3.67)×109 were noticed in ill children of RVH(P<0.05).According to logistic regression,interval between onset and visit nlore than 3 days,body tem-perature at the first visit higher than 38.5℃,WBC count over 10.0×109,and the accompaniment of serious symptoms were confirmed to be independent risk factors involved in RVH.Of them,67.85%(11/16)ill children with three or more risk factors of RVH showed diagnosis sensitivity and specificity reach to 64.53%and 97.14%,respectively.Conclusions Risk factors confirmed are the interval between onset and the visist more than 3 days,bodv temperature higher than 38.5℃ at the first visit,WBC count more than 10.0×109,and the accompaniment of severe symptoms.The ill children with three or more risk factors are in great request of more closely monitoring and should not be the candidates for repatriation to family or community after preliminary diagnosis.

BACKGROUND:In recent years,the development of liver organoids has made it a hot spot in the field of international liver disease research,but there is still no article on the bibliometric analysis of liver organoids. OBJECTIVE:To explore the hot trends in liver organoids in the last 20 years based on bibliometrics and visualization analysis. METHODS:We searched the articles about liver organoids in the Web of Science Core Collection from January 1,2002 to November 12,2022.Origin,Office,and CiteSpace software were used for bibliometrics and visualization analysis.We statistically analyzed the number of annually published articles,countries,institutions,authors,journals,and keywords of the articles by generating charts. RESULTS AND CONCLUSION:The number of articles,citation frequency,institutions and personnel involved in the research about liver organoids showed an overall upward trend in the last 20 years,indicating that the field was growing rapidly and attention was increasing.The USA had published the most papers and had the strongest influence in this field.Although it had invested a lot of time and energy,the number of papers published by a single research institution in the USA was not the highest among many research institutions.China was second only to the USA in the number of publications,with the Chinese Academy of Sciences and Fudan University leading the list.Utrecht University in the Netherlands was the institution with the most publications.Clevers H was the author with the highest number of articles.The article with the highest co-citation frequency was"Long-term culture of genome-stable bipotent stem cells from adult human liver".The main fields of study for liver organoids were Molecular Science,Biology,and Immunology.The most frequently occurring keywords were stem cell,in vitro,and culture.The research hotspots in the liver organoids field were mainly focused on in vitro stem cell three-dimensional culture,differentiation and gene expression.
