| 1 | Comparison of neutron energy spectrum unfolding methods and evaluation of rationality criteria显示文摘The neutron energy spectrum was measured using a Bonner sphere spectrometer at six locations inside the containment vessel of a nuclear reactor at the Qinshan nuclear power plant. The structures of the neutron spectra obtained by the maximum entropy, iteration, and genetic algorithm methods were consistent with one another and could be interpreted as the spectral superposition of different energy regions. The characteristic parameters of the neutron spectrum, including the fluence rate,average energy, and neutron ambient dose equivalent rate H^(*)(10), were in good agreement among the three methods. In addition, an LB6411 neutron ambient dose equivalent meter was employed to obtain the H^(*)(10) directly for comparison.These findings indicate that neutron spectrum unfolding methods can be used to overcome the problems associated with the response functions of dosimeters to provide more accurate H^(*)(10) values. In this study, the following three evaluation criteria were systematically addressed to ensure the accuracy of the unfolded spectra: count rates of the inverse solutions,neutron spectrum structures, and comparison of key parameters. | Jun‑Kai Yang Ping‑Quan Wang Zhong‑Guo Ren Ren‑Sheng Wang Hui Zhang Jian Zhang | 2022 | Nuclear Science and Techniques2022，33，12： | 0 |
| 2 | Pediatric patients in the new wave of SARS‑CoV‑2 infection in Shanghai,China显示文摘Since March 28,2022,Shanghai has become the new COVID-19 epicenter in China,with more than 500,000 COVID-19 cases until May 5th,2022,of which more than 90%are asymptomatic.More than 12,000 children in Shanghai were infected with COVID-19 during the current Omicron wave,which was characterized by family clustering.Because an increasing number of symptomatic children are required to be hospitalized,four major pediatric medical centers in Shanghai and other general hospitals were designated for admitting symptomatic pediatric COVID-19 cases in the early April.There were approximately 3,500 pediatric cases admitted from April 1st until May 5th,2022. | Jian‑Guo Zhou Yan‑Ming Lu Li‑Bo Wang Hui Yu Ting Zhang Yi‑Wei Chen Wen‑Hao Zhou | 2022 | World Journal of Pediatrics2022，18，9： | 0 |
| 3 | A gross deletion of the PAX3 gene in a large Chinese family with Waardenburg syndrome type Ⅰ显示文摘Waardenburg syndrome(WS)is an autosomal-dominant neurocristopathy characterized by sensorineural hearing loss(SNHL)and pigmentary abnormalities of the iris,hair,and skin.It is responsible for approximately 3%of congenital hearing loss[1].WS is thought to be fully penetrant when considering at least one clinical feature,but the penetrance of each feature is not complete[2].Four types of WS have been classifed based on the clinical manifestations.WS1 is one of the most common forms of WS.To confrm the diagnosis of WS1,at least two major or one major plus two minors of the Waardenburg consortium criteria must be present.In brief,major criteria include congenital sensorineural hearing loss,pigmentary disturbances of the iris,hair hypopigmentation,dystopia canthorum(average W index of afected family members is greater than 1.95)and afected frst-degree relatives.Minor criteria include skin hypopigmentation,synophyrys or medial eyebrow fare,broad and high nasal root,hypoplasia of alae nasi,and premature graying of hair[3].High phenotypic heterogeneity has been observed in WS1,even in the same family[4]. | Shu‑Zhi Yang Lei Hou Xin Qi Guo‑Jian Wang Sha‑Sha Huang Shan‑Shan Zhang Bang‑Qing Huang Ying Yang Bei‑Cheng Li Shuo Liu Pu Dai Yu Su | 2023 | World Journal of Pediatrics2023，19，12： | 0 |
| 4 | Green Vertical‑Cavity Surface‑Emitting Lasers Based on InGaN Quantum Dots and Short Cavity显示文摘Room temperature low threshold lasing of green GaNbased vertical cavity surface emitting laser(VCSEL)was demonstrated under continuous wave(CW)operation.By using self-formed InGaN quantum dots(QDs)as the active region,the VCSEL emitting at 524.0 nm has a threshold current density of 51.97 A cm^(-2),the lowest ever reported.The QD epitaxial wafer featured with a high IQE of 69.94%and theδ-function-like density of states plays an important role in achieving low threshold current.Besides,a short cavity of the device(~4.0λ)is vital to enhance the spontaneous emission coupling factor to 0.094,increase the gain coefficient factor,and decrease the optical loss.To improve heat dissipation,AlN layer was used as the current confinement layer and electroplated copper plate was used to replace metal bonding.The results provide important guidance to achieving high performance GaN-based VCSELs. | Tao Yang Yan‑Hui Chen Ya‑Chao Wang Wei Ou Lei‑Ying Ying Yang Mei Ai‑Qin Tian Jian‑Ping Liu Hao‑Chung Guo Bao‑Ping Zhang | 2023 | Nano-Micro Letters2023，15，12： | 0 |
| 5 | Best practice for infection prevention in pediatric respiratory clinics during the COVID‑19 epidemic显示文摘During the COVID-19 epidemic,it is important for ensuring infection prevention and control in the pediatric respiratory clinics.Herein,we introduced the practice of infection prevention and control in pediatric respiratory clinics in China.Triage measures for patients who visit respiratory clinics,quality control for pediatric respiratory clinics and other preventive measures for related examinations and treatment have been introduced in this review article. | Jing Zhang Lei Zhang Yong Yin Quan Lu Jian‑Guo Hong Xiao‑Bo Zhang Xiao‑Jian Zhou Li‑Bo Wang Jian‑Hua Zhang Min Lu Xiao‑Yan Dong Jie Shao Yan‑Ming Lu Jun Yu Li Gu Respiratory Disease Group,Pediatric Committee of Shanghai Medical Association,Shanghai,China | 2020 | World Journal of Pediatrics2020，16，4： | 0 |
| 6 | Altered gut microbiota composition in children and their caregivers infected with the SARS‑CoV‑2 Omicron variant显示文摘Background Gut microbiota alterations have been implicated in the pathogenesis of coronavirus disease 2019(COVID-19).This study aimed to explore gut microbiota changes in a prospective cohort of COVID-19 children and their asymptomatic caregivers infected with the severe acute respiratory syndrome coronavirus type 2(SARS-CoV-2)Omicron variant.Methods A total of 186 participants,including 59 COVID-19 children,50 asymptomatic adult caregivers,52 healthy children(HC),and 25 healthy adults(HA),were recruited between 15 April and 31 May 2022.The gut microbiota composition was determined by 16S rRNA gene sequencing in fecal samples collected from the participants.Gut microbiota functional profling was performed by using Phylogenetic Investigation of Communities by Reconstruction of Unobserved States(PICRUSt)software.Results The gut microbiota analysis of beta diversity revealed that the fecal microbial community of COVID-19 children remained far distantly related to HC.The relative abundances of the phyla Actinobacteria and Firmicutes were decreased,whereas Bacteroidetes,Proteobacteria,and Verrucomicrobiota were increased in COVID-19 children.Feces from COVID-19 children exhibited notably lower abundances of the genera Blautia,Bifdobacterium,Fusicatenibacter,Streptococcus,and Romboutsia and higher abundances of the genera Prevotella,Lachnoclostridium,Escherichia-Shigella,and Bacteroides than those from HC.The enterotype distributions of COVID-19 children were characterized by a high prevalence of enterotype Bacteroides.Similar changes in gut microbiota compositions were observed in asymptomatic caregivers.Furthermore,the microbial metabolic activities of KEGG(Kyoto Encyclopedia of Genes and Genomes)and COG(cluster of orthologous groups of proteins)pathways were perturbed in feces from subjects infected with the SARS-CoV-2 Omicron variant.Conclusion Our data reveal altered gut microbiota compositions in both COVID-19 children and their asymptomatic caregivers infected with the SARS-CoV-2 Omicron variant,which further implicates the critical role of gut microbiota in COVID-19 pathogenesis. | Yi‑Zhong Wang Jian‑Guo Zhou Yan‑Ming Lu Hui Hu Fang‑Fei Xiao Ting Ge Xing Wang Lu Zheng Lian‑Hu Yu Jun Le Hui Yu Guang‑Jun Yu Qiang Xia Ting Zhang Wen‑Hao Zhou | 2023 | World Journal of Pediatrics2023，19，5： | 0 |
