| 1 | Diagnosis, treatment, and prevention of 2019 novel coronavirus infection in children: experts' consensus statement显示文摘Since the outbreak of 2019 novel coronavirus infection (2019-nCoV) in Wuhan City,China,by January 30,2020,a total of 9692 confirmed cases and 15,238 suspected cases have been reported around 31 provinces or cities in China.Among the confirmed cases,1527 were severe cases,171 had recovered and been discharged at home,and 213 died.And among these cases,a total of 28 children aged from 1 month to 17 years have been reported in China.For standardizing prevention and management of 2019-nCoV infections in children,we called up an experts' committee to formulate this experts' consensus statement.This statement is based on the Novel Coronavirus Infection Pneumonia Diagnosis and Treatment Standards (the fourth edition) (National Health Committee) and other previous diagnosis and treatment strategies for pediatric virus infections.The present consensus statement summarizes current strategies on diagnosis,treatment,and prevention of 2019-nCoV infection in children. | Kunling Shen Yonghong Yang Tianyou Wang Dongchi Zhao Yi Jiang Runming Jin Yuejie Zheng Baoping Xu Zhengde Xie Likai Lin Yunxiao Shang Xiaoxia Lu Sainan Shu Yan Bai Jikui Deng Min Lu Leping Ye Xuefeng Wang Yongyan Wang Liwei Gao | 2020 | World Journal of Pediatrics2020，16，3： | 56 |
| 2 | A Multicenter Study of Viral Aetiology of Community-Acquired Pneumonia in Hospitalized Children in Chinese Mainland显示文摘Community-acquired pneumonia(CAP) is one of the leading causes of morbidity and mortality in children worldwide.In this study,we aimed to describe the aetiology of viral infection of pediatric CAP in Chinese mainland.During November2014 to June 2016,the prospective study was conducted in 13 hospitals.The hospitalized children under 18 years old who met the criteria for CAP were enrolled.The throat swabs or nasopharyngeal aspirates(NPAs) were collected which were then screened 18 respiratory viruses using multiplex PCR assay.Viral pathogens were present in 56.6%(1539/2721) of the enrolled cases,with the detection rate of single virus in 39.8% of the cases and multiple viruses in 16.8% of the cases.The most frequently detected virus was respiratory syncytial virus(RSV)(15.2%,414/2721).The highest detection rate of virus was in <6-month-age group(70.7%,292/413).RSV,human metapneumovirus(HMPV),human parainfluenza viruses(HPIVs) and influenza B virus(Flu B) showed the similar prevalence patterns both in north and south China,but HPIVs,Flu A,human bocavirus(HBoV),human adenovirus(HAdV) and human coronaviruses(HCoVs) showed the distinct circulating patterns in north and south China.Human enterovirus/human rhinovirus(HEV/HRV)(27.6%,27/98),HBoV(18.4%,18/98),RSV(16.3%,16/98) and HMPV(14.3%,14/98) were the most commonly detected viruses in severe pneumonia cases with single virus infection.In conclusion,viral pathogens are frequently detected in pediatric CAP cases and may therefore play a vital role in the aetiology of CAP.RSV was the most important virus in hospitalized children with CAP in Chinese mainland. | Yun Zhu Baoping Xu Changchong Li Zhimin Chen Ling Cao Zhou Fu Yunxiao Shang Aihuan Chen Li Deng Yixiao Bao Yun Sun Limin Ning Shuilian Yu Fang Gu Chunyan Liu Ju Yin Adong Shen Zhengde Xie Kunling Shen | 2021 | Virologica Sinica2021，36，6： | 7 |
| 3 | Synthesis, characterization and tribological evaluation of novel1,4-diazabicyclo[2.2.2]octane based dicationic ionic liquids as efficient antiwear lubricant additives显示文摘Ionic liquids have developed and been applied in lubricant field since 2001. Nevertheless, it is little known about novel dicationic ionic liquids for tribology applications in the past several years. In this paper, a sequence of novel dicationic ionic liquids based on 1,4-diazabicyclo[2.2.2]octane cations(DABCO) and different anions have been designed and identified. The structures of ILs were confirmed by Fourier transform infrared(FTIR) spectra, multinuclear(~1H,^(13)C,^(11)B,^(31)P and ^(19)F) magnetic resonance and mass spectrometry. The effects of anion type on thermal properties, wettability, kinematic viscosity and tribological properties were studied. It is found that all of these dicationic ionic liquids as additives exhibit excellent anti-wear and friction-reducing properties in PEG synthetic base oil under boundary lubrication conditions for steel-to-steel contact, which offers great potential for the highly efficient lubricant additives. Simultaneously, novel 1,4-diazabicyclo[2.2.2]octane cation offers an exceptional chance for the research and development of dicationic ionic liquids in various applications. | ZHAO LiNa CAI Tao ZHANG YunXiao YE MengTing SHANG WangJi LIU Dan TONG DingYi LIU ShengGao | 2019 | Science China(Technological Sciences)2019，62，2： | 3 |

| 5 | Epidemiological characteristics and clinical manifestations of pediatric patients with COVID-19 in China: A multicenter retrospective study显示文摘Importance:The Coronavirus disease 2019(COVID-19)global pandemic poses a considerable challenge for pediatricians.Objective:This study aimed to identify the epidemiological characteristics and clinical features of pediatric patients with COVID-19 in China.Methods:This multicenter retrospective study included pediatric patients from 46 hospitals in China,covering 12 provinces and two municipalities.Epidemiological,demographic,clinical,laboratory,treatment,and outcome data were analyzed.Results:In total,211 pediatric patients with COVID-19 were included in this study.The median age was 7.0 years(range:22 days to 18 years).Approximately 16.3%of the patients exhibited asymptomatic infections,23.0%had upper respiratory tract infections,and 60.7%had pneumonia,including two with severe pneumonia and one with critical illness.Approximately 78.7%of the pediatric patients occurred in familial clusters.The most three common symptoms or signs at onset in children with COVID-19 were fever(54.5%),cough(49.3%),and pharyngeal congestion(20.8%).Only 17.6%of the patients presented with decreased lymphocyte count,whereas 13.6%had increased lymphocyte count.Among the patients with pneumonia who exhibited abnormal chest computed tomography findings,18.2%(23/127)of the patients had no other symptoms.Generally,the chest radiographs showed abnormalities that affected both lungs(49.6%);ground-glass opacity(47.2%)was the most common manifestation.The cure and improvement rates were 86.7%(183/211)and 13.3%(28/211),respectively.Only one patient with an underlying condition received invasive mechanical ventilation;none of the patients died.Interpretation:Similar to adults,children of all age groups are susceptible to COVID-19.Fortunately,most pediatric patients have mild symptoms or remain asymptomatic,despite the high incidence of pneumonia.Decreased proportions of white blood cells and lymphocytes are less frequent in children than in adults. | Yan Bai Liwei Gao Xianfeng Wang Lili Zhong Jingfeng Li Shenggang Ding Yuejie Zheng Jun Liu Yuxia Cui Lina Wang Mingfeng Han Jun Liu Xinping Jiang Min Jiang Junhua Li Ning Chen Yunxiao Shang Hourong Zhou Yi Xu Gen Lu Xing Chen Jizhi Xu Qihong Fan Yu Tang Jiang Wu Cen Li Xiaoxiang Yang Chunxi Chen Yonghong Yang Gary Wing-Kin Wong Adong Shen Tianyou Wang Runming Jin Baoping Xu Kunling Shen | 2021 | Pediatric Investigation2021，5，3： | 0 |
