| 1 | Epidemiological Characteristics of Newly-Reported HIV Cases Among Youth Aged 15−24 Years-China, 2010−2019显示文摘Summary What is already known about this topic?An estimated 1,400 new cases of human immunodeficiency virus(HIV)occur every day among youths globally.However,HIV distribution among youth aged 15–24 years in China has not been researched extensively. | Hao Zhao Hui Liu Lu Wang Xuan Yang Shaorong Wang Mengjie Han Jian Li | 2020 | China CDC weekly2020，2，48： | 23 |
| 2 | TOPOLOGY OPTIMIZATION OF TRUSS STRUCTURES WITH SYSTEMATIC RELIABILITY CONSTRAINTS UNDER MULTIPLE LOADING CASES显示文摘In this paper,a mathematical model for topology optimization of truss structures withconstraints of displacement and system reliability under multiple loading cases is constructed.In orderto avoid the difficulty of computing the structure’s system reliability,a solving approach is presented inwhich the failure probability of system is divided into the sum of all bars’ failure probability by meansof reliability distribution.In addition,by drawing into the reliability safety factor and the fundamen-tal relationship in structural mechanics,all probability constraints of displacement and stress are equiv-alently displayed as conventional form and linear function of the design variables.The optimizationproblem with multiple constraints is treated by the compact constraint tactics and is solved by the im-proved simplex method.The examples show that the approach proposed in this paper is feasible and ef-ficient. | Chen Jianjun Cao Yibo Sun Huaian | 1999 | Acta Mechanica Solida Sinica1999，12，2： | 8 |
| 3 | Spatial prediction of landslide susceptibility using GIS-based statistical and machine learning models in Wanzhou County,Three Gorges Reservoir, China显示文摘Landslide susceptibility mapping is vital for landslide risk management and urban planning.In this study,we used three statistical models[frequency ratio,certainty factor and index of entropy(IOE)]and a machine learning model[random forest(RF)]for landslide susceptibility mapping in Wanzhou County,China.First,a landslide inventory map was prepared using earlier geotechnical investigation reports,aerial images,and field surveys.Then,the redundant factors were excluded from the initial fourteen landslide causal factors via factor correlation analysis.To determine the most effective causal factors,landslide susceptibility evaluations were performed based on four cases with different combinations of factors('cases').In the analysis,465(70%)landslide locations were randomly selected for model training,and 200(30%)landslide locations were selected for verification.The results showed that case 3 produced the best performance for the statistical models and that case 2 produced the best performance for the RF model.Finally,the receiver operating characteristic(ROC)curve was used to verify the accuracy of each model's results for its respective optimal case.The ROC curve analysis showed that the machine learning model performed better than the other three models,and among the three statistical models,the IOE model with weight coefficients was superior. | Ting Xiao Kunlong Yin Tianlu Yao Shuhao Liu | 2019 | Acta Geochimica2019，38，5： | 8 |
| 4 | Transradial versus transfemoral access for anterior circulation mechanical thrombectomy: analysis of 375 consecutive cases显示文摘Objective To compare transradial artery access(TRA)to the gold standard of transfemoral artery access(TFA)in mechanical thrombectomy(MT)for stroke caused by anterior circulation large vessel occlusion.Methods The clinical outcomes,procedural speed,angiographic efficacy and safety of both techniques were analysed in 375 consecutive cases over an 18-month period in a high volume statewide neurointerventional service.Results There was no significant difference in patient characteristics,stroke parameters,imaging techniques or intracranial techniques.The median time elapsed between CT scanning and reperfusion was 96.5 min(IQR 68-123)in the TFA group and 95 min(IQR 68-123)in the TRA group(p=0.456).Of 336 patients who were independent at presentation 58%(124/214)of the TFA group and 67%(82/122)of the TRA group had a modified Rankin score of 0-2 at 90-day follow-up(p=0.093).Cross-over from radial to femoral was 4.6%(4/130)compared with 1.6%cross-over from femoral to radial(4/245),but did not meet the predetermined level of statistical significance(OR2.92,95% CI 0.81 to 10.52,p=0.088) and did not impact median procedural speed.Adequate angiographic reperfusion,first pass reperfusion,embolisation to new territory and symptomatic intracranial haemorrhage were similar in both groups.There was a significant difference in major access site complications requiring an additional procedure.None of the TRA cases had a major access site complication but 6.5%(16/245)of the TFA cases did(p=0.003).Conclusion This study suggests that using TRA for anterior circulation MT is fast,efficacious,safe and not inferior to the gold standard of TFA. | Timothy John Phillips Matthew Thomas Crockett Gregory D Selkirk Ruchi Kabra Albert Ho Yuen Chiu Tejinder Singh Constantine Phatouros William McAuliffe | 2021 | Stroke & Vascular Neurology2021，6，2： | 7 |
| 5 | Reemergent Cases of COVID-19—Xinfadi Wholesales Market,Beijing Municipality,China,June 11,2020显示文摘No new local coronavirus disease 2019(COVID-19)cases were reported in Beijing for over 56 days before the reemergent COVID-19 cases that were reported on June 11,2020,and more than 200 confirmed cases have been reported as of June 20 in Beijing.All confirmed COVID-19 cases were associated with Xinfadi Wholesale Market.Here,we reported the phylogenetic characteristics of the COVID-19 viruses(also known as severe acute respiratory syndrome coronavirus 2,SARS-CoV-2,and human coronavirus 2019,HCoV-19)sequenced from the clinical specimens of 2 human cases and 1 environmental sample. | Wenjie Tan Peihua Niu Xiang Zhao Yang Pan Yong Zhang Lijuan Chen Li Zhao Yanhai Wang Dayan Wang Jun Han George FGao Chun Huang Wenbo Xu Guizhen Wu | 2020 | China CDC weekly2020，2，27： | 6 |
| 6 | Evolutionary perspectives on novel coronaviruses identified in pneumonia cases in China显示文摘Coronaviruses,such as severe acute respiratory syndrome coronavirus(SARSCoV)and Middle East respiratory syndrome coronavirus(MERS-CoV),are highly transmissible pathogens,and they can be lethal in humans.Bats are believed to be the original sources of these lethal pathogens.In December 2019,a cluster of pneumonia cases was reported in W uhan and a novel coronavirus(2019-nCoV,now officially named as SARSCoV-2)has been linked to the causative agent.Early studies indicated that the new virus was genetically similar to a bat betacoronavirus,providing evidence for bat origin of the third human-infecting coronavirus in less than 20 years.We here highlight the potential for viral spillover from animals to humans and discuss evolutionary mechanisms leading to the outbreaks. | Xiaoman Wei Xiang Li Jie Cui | 2020 | National Science Review2020，7，2： | 6 |
| 7 | Novel antibody epitopes dominate the antigenicity of spike glycoprotein in SARS-CoV-2 compared to SARS-CoV显示文摘Recently,the World Health Organization(WHO)has declared the novel coronavirus(2019-nCoV)outbreak a Public Health Emergency of International Concern(PHEIC),1 which is now formally named as severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).2 As of 27 February 2020,a total of 82,178 cases of SARS-CoV-2 infection have been confirmed across the world,with 78,630 cases in China(https://ncov.dxy.cn/ncovh5/view/pneumonia?source=).The SARSCoV-2 has been determined as the seventh member of the coronaviruses infected humans.3 Moreover,similar to severe acute respiratory syndrome coronavirus(SARS-CoV)and Middle East respiratory syndrome coronavirus(MERS-CoV),the SARS-CoV-2 could also cause severe and fatal illness.3 Since the SARS-CoV-2 outbreak,there have been approximately 14,792 clinically severe cases and 2800 dead cases. | Ming Zheng Lun Song | 2020 | Cellular & Molecular Immunology2020，17，5： | 5 |
| 8 | The Spatiotemporal Dynamic Distributions of New Tuberculosis in Hangzhou,China显示文摘Pulmonary tuberculosis(TB)remains a global health threat worldwide,despite the availability of effective antibiotics for drug-sensitive TB for decades.This is in part due to the ongoing transmission from cases of undiagnosed TB[1]and drug-resistant TB(DR-TB)[1].China has the second largest number of multidrug-resistant TB(MDR-TB)cases worldwide,which is estimated at 73,000 MDRTB or rifampicin-resistant TB(RR-TB)cases and accounts for 13%of the global burden[1].The results of China’s Fifth National TB Epidemiological Survey indicated that the prevalence of TB in the western region was more than three times the eastern region. | ZENG Mei Chun JIA Qing Jun HUANG Yin Yan | 2020 | Biomedical and Environmental Sciences2020，33，4： | 4 |

| 10 | Persistent fifth aortic arch stenosis associated with type A interruption of the aortic arch: a report of six cases显示文摘Persistent fifth aortic arch (PFAA) is a rare congenital cardiovascular malformation that occurs when the pharyngeal fifth aortic arch does not degenerate during the embryonic period. The first case of PFAA was described in an autopsy specimen in 1969.[1] In 1973, the persistence of a left fifth aortic arch was first reported.[2] Since then, several case reports have described PFAA in different forms. PFAA stenosis associated with type A interruption of the aortic arch (type-A IAA) is most common in clinical practice and requires surgical intervention. From 2013 to 2018, six cases [Table 1 and Table 2] were diagnosed using echocardiography and computed tomography angiography (CTA). Five cases were successfully treated with surgery and followed-up. The purpose of this study was to summarize the clinical characteristics and diagnostic features of PFAA stenosis associated with type-A IAA to improve its diagnostic accuracy and allow for complete pre-operative preparation and proper treatment. | Lin Zheng Yong-Li Cao Rong-Chang Wu Jian Guo Ning Ma Fang-Yun Wang Xin Zhang Yun Peng | 2019 | Chinese Medical Journal2019，，12： | 4 |

| 18 | Relationship between FAC at plasma sheet boundary layers and AE index during storms from August to October,2001显示文摘Unlike the previous single (dual) satellite observation, the four ClusterII satellites make it possible to directly compute the continuous field-aligned current (FAC) density according to the magnetic data from them and to enable the investigation of the relationship between the FAC and geomagnetic activity. This paper analyzes the observation data when the Cluster satellites crossed the plasma sheet bound- ary layer (PSBL) in the magnetotail during the two magnetic storms in August to October 2001. According to the data, during the magnetic storms the relationship between the variations of FAC and AE index turned out to be: 1) FAC was obviously increasing during the storms; 2) FAC density was approximately negatively corre- lated with AE index from the sudden commencement to the early main phase of the storm; 3) they were approximately positively correlated during the late main phase and early recovery phase; 4) they were no apparent correlation during the late re- covery phase. | DUNLOP M | 2008 | Science China(Technological Sciences)2008，51，7： | 2 |
| 19 | An Economic Analysis of Third Party Litigation Funding显示文摘Third party litigation funding(TPLF)is one of the most innovative trends in litigation funding industry.In a TPLF contract,an external investor(the third party funder)financially supports a litigant to cover litigation expenses.If the claim is finally successful,a share of recoveries will come to the funder in return.On the other hand,the third party funder will receive no compensation if the plaintiff loses the suit.Up till now,in some common law jurisdictions(e.g.,Australia,the UK,and the U.S.),TPLF has been legally accepted and develops rapidly.Meanwhile,concerns about the use of TPLF have also been raised.For example,whether TPLF will encourage frivolous suits and unmeritorious claims;and whether the use of TPLF will be socially desirable.In this article,a basic economic model of TPLF will be built firstly.Then,analysis based on this model will be delivered and further social externalities brought by the use of TPLF will also be investigated.Finally,through an economic analysis,it is concluded that TPLF is generally social desirable but regulations should be imposed. | CHEN Wenjing | 2019 | US-China Law Review2019，16，1： | 1 |
| 20 | A Familial Phenotypic and Genetic Study of Mutations in PFN1 Associated with Amyotrophic Lateral Sclerosis显示文摘Dear Editor,Amyotrophic lateral sclerosis(ALS)is a progressive and fatal neurodegenerative disease that prominently affects both upper and lower motor neurons.The prevalence of ALS has been estimated at 2.6-3.0 per 100,000 in Europe,5.2 per 100,000 in the USA,and 1.9-9.9 per 100,000 in Asia[1-3].ALS is classified as sporadic(sALS)or familial(fALS),but only 5%-10% of cases are identified as familial[4,5]. | Jieshan Chi Junling Chen Yan Li Zhiheng Huang Lijuan Wang Yuhu Zhang | 2020 | Neuroscience Bulletin2020，36，2： | 1 |
