12018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up.Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu 2018Science Bulletin2018,63,23:54
2Bevacizumab biosimilar LY01008 compared with bevacizumab(Avastin)as first-line treatment for Chinese patients with unresectable,metastatic,or recurrent non-squamous non-small-cell lung cancer:A multicenter,randomized,double-blinded,phase Ⅲ trial显示文摘Background:Previous studies have demonstrated the preclinical pharmacological and toxicological consistency,and clinical pharmacokinetic equivalence of bevacizumab biosimilar LY01008 with reference bevacizumab(Avastin).This randomized controlled trial aimed to compare the efficacy and safety of LY01008 with Avastin in first-line treatment of Chinese patients with advanced or recurrent non-squamous non-small cell lung cancer(NSCLC).Methods:StageⅢB-ⅣNSCLC patients with evaluable lesions,good physical status,and adequate organ functions from 67 centers across China were randomized in a ratio of 1:1 to receive LY01008 or Avastin 15 mg/kg intravenously in combination with paclitaxel/carboplatin(combined treatment)for 4-6 cycles,followed by maintenance monotherapy with LY01008 until disease progression,intolerable toxicity,or death.The primary endpoint was objective response rate(ORR)in accordance with Response Evaluation Criteria in Solid Tumors(RECIST)version 1.1 confirmed by independent radiological review committees(IRRC).Secondary endpoints included disease control rate(DCR),duration of response(DoR),progression-free survival(PFS),overall survival(OS),and safety.This study was registered in Clinical Trials.gov(NCT03533127).Results:Between December 15^(th),2017,and May 15^(th),2019,a total of 649 patients were randomized to the LY01008(n=324)or Avastin(n=325)group.As of September 25th,2019 for primary endpoint analysis,589 patients received ORR evaluation,with a median number of combined treatment cycles of 5(range 1-6)andmedian duration of treatment of 3.0(range 0.0-5.1)months.ORRof responseevaluable patients in the LY01008 and Avastin groups were 48.5% and 53.0%,respectively.The stratified ORR ratio was 0.91(90%CI 0.80-1.04,within the prespecified equivalence margin of 0.75-1.33).Up to May 15^(th),2020,with a median follow-up of 13.6(range 0.8-28.4)months,no notable differences in DCR,median DoR,median PFS,median OS,and 1-year OS rate were observed between the LY01008 and Avastin groups.There were no clinically meaningful differences in safety and immunogenicity across treatment groups.Conclusions:LY01008 demonstrated similarity to Avastin in terms of efficacy and safety in Chinese patients with advanced or recurrent non-squamous NSCLC.LY01008 combined with paclitaxel/carboplatin is expected to become a new treatment option for unresectable,metastatic,LY01008 and Avastin groups.There were no clinically meaningful differences in safety and immunogenicity across treatment groups.Conclusions:LY01008 demonstrated similarity to Avastin in terms of efficacy and safety in Chinese patients with advanced or recurrent non-squamous NSCLC.LY01008 combined with paclitaxel/carboplatin is expected to become a new treatment option for unresectable,metastatic,or recurrent non-squamous NSCLC patients in the first-line setting.Yuankai Shi Kaijian Lei Yuming Jia Bingqiang Ni Zhiyong He Minghong Bi Xicheng Wang Jianhua Shi Ming Zhou Qian Sun Guolei Wang Dongji Chen Yongqian Shu Lianke Liu Zhongliang Guo Yong Liu Junquan Yang Ke Wang Ke Xiao LinWu Tienan Yi Debin Sun Mafei Kang Tianjiang Ma Yimin Mao Jinsheng Shi Tiegang Tang Yan Wang Puyuan Xing Dongqing Lv Wangjun Liao Zhiguo Luo Bin Wang Xiaohong Wu Xiaoli Zhu Shuhua Han Qisen Guo Rongyu Liu Zhiwei Lu Jianyong Zhang Jian Fang Changlu Hu Yinghua Ji Guolong Liu Hong Lu Dedong Wu Junhong Zhang Shuyang Zhu Zheng Liu Wensheng Qiu Feng Ye Yan Yu Yanqiu Zhao Qinhong Zheng Jun Chen Zhanyu Pan Yiping Zhang Wenjuan Lian Bo Jiang Bo Qiu Guojun Zhang Hua Zhang Yanju Chen Yuan Chen Hongbing Duan Manxiang Li Shengming Liu Lijun Ma Hongming Pan Xia Yuan Xueli Yuan Yulong Zheng Emei Gao Li Zhao Shumin Wang Can Wu 2021Cancer Communications2021,41,9:5
3Vehicular Beacon Broadcast Scheduling Based on Age of Information(AoI)显示文摘Vehicular beaconing plays an important role to facilitate various applications in the paradigm of Internet of Vehicles(IoV). Due to high dynamic and resource limitation in IoV, how to schedule the vehicular beacon broadcast is challenging, especially in dense scenarios. In this paper, we investigate the beacon broadcast scheduling problem considering the Age of Information(AoI). We first propose an algorithm minimizing the expected sum of AoI considering the limited communication resource and vehicle mobility. Then the performance of the proposed algorithm is analyzed. With the proposed algorithm, the optimal solution can be obtained under certain conditions. Extensive simulations are conducted to verify the efficiency, effectiveness and fairness of the proposed solution.Yuanzhi Ni Lin Cai Yuming Bo 2018China Communications2018,15,7:4
4Effects of dietary tryptophan and stocking density on the performance,meat quality,and metabolic status of broilers显示文摘Background:Highly automated cage-rearing systems are becoming increasingly popular in China.However,a high stocking density can cause oxidative stress and decrease broiler performance.The tryptophan(TRP) derivative5-hydroxytryptophan(5-HT) has been shown to preserve membrane fluidity in birds suffering from oxidative stress.Therefore,this experiment was conducted to determine the effects of dietary TRP supplementation on performance,breast meat quality and oxidative stress in broilers reared in cages with a high or low stocking density.Methods:Female Arbor Acres broilers(25-d-old,n=144) were randomly allocated to 1 of 4 treatments.The birds were fed a diet based on corn,soybean meal,cottonseed meal and corn gluten meal containing either 0.18 or 0.27%TRP and were housed with stocking densities of 11 or 15.4 birds/m2 in a 2 × 2 factorial experiment.Broiler performance was evaluated from d 25 to 42.Eight birds from each treatment were slaughtered on d 42 and plasma and breast muscle samples were collected to measure biochemical indices.Results:A higher stocking density tended to be associated with reduced weight gain(P<0.10),and significantly increased plasma glutamic-pyruvic transaminase(GPT) activity(P<0.001).Increased dietary TRP significantly reduced the activities of lactic dehydrogenase and GPT while increasing total cholesterol in the plasma(P<0.01),reducing drip loss of breast muscle(P<0.10) and improving feed efficiency(P<0.10).Conclusions:An increase in dietary TRP,1.5-fold higher than the standard supplementation level,can alleviate oxidative stress as well as improve welfare and feed efficiency in broilers reared in cages with a high stocking density.Bo Wang Zhizhi Min Jianmin Yuan Bingkun Zhang Yuming Guo 2015Journal of Animal Science and Biotechnology2015,6,1:4
5Prognostic value of systemic immune- inflammation index in acute/subacute patients with cerebral venous sinus thrombosis显示文摘Objective To evaluate the prognosis values of systemic immune-inflammation index(SII)in non-chronic cerebral venous sinus thrombosis(CVST).Methods patients with CVST,admitted to the First Affiliated Hospital of Zhengzhou University,were retrospectively identified from January 2013 to December 2018.We selected patients in acute/subacute phase from database.Functional outcomes of patients were evaluated with the modified Rankin Scale(mRS)-mRS 3-6 as poor outcomes and mRS 6 as death.The overall survival time was defined as the date of onset to the date of death or last follow-up date.Survival analysis was described by the Kaplan-Meier curve and Cox regression analysis.Multivariate logistic regression analysis assessed the relationship between SII and poor functional outcome.The area under the Receiver Operating Curve curve(AUC)was estimated to evaluate the ability of SII in prediction.Results A total of 270 patients were included and their duration of follow-up was 22 months(6-66 months),of whom 31 patients had poor outcomes and 24 patients dead.Cox regression analysis showed that SII(HR=1.304,95%CI:1.101 to 1.703,p=0.001)was a predictor of death in non-chronic CVST.Patients with higher SII presented lower survival rates(p=0.003).The AUC of SII was 0.792(95%CI:0.695 to 0.888,p=0.040)with a sensitivity of 69.6%and specificity of 80.1%.Subgroups analysis demonstrated that SII was an important predictor of poor outcomes in male(OR=1.303,95%CI:1.102 to 1.501,p=0.011)and pregnancy/puerperium female(OR=1.407,95%CI:1.204 to 1.703,p=0.034).Conclusions SII was a potential predictor in the poor prognosis of patients with acute/subacute CVST,especially in male and pregnancy/puerperium female.Shen Li Kai Liu Yuan Gao Lu Zhao Rui Zhang Hui Fang Yongli Tao Hongbing Liu Jiawei Zhao Zongping Xia Yuming Xu Bo Song 2020Stroke & Vascular Neurology2020,5,4:3
6Overview of the Solar Polar Orbit Telescope Project for Space Weather Mission显示文摘The Solar Polar ORbit Telescope(SPORT) project for space weather mission has been under intensive scientific and engineering background studies since it was incorporated into the Chinese Space Science Strategic Pioneer Project in 2011.SPORT is designed to carry a suite of remote-sensing and in-situ instruments to observe Coronal Mass Ejections(CMEs),energetic particles,solar high-latitude magnetism,and the fast solar wind from a polar orbit around the Sun.The first extended view of the polar regions of the Sun and the ecliptic enabled by SPORT will provide a unique opportunity to study CME propagation through the inner heliosphere,and the solar high-latitude magnetism giving rise to eruptions and the fast solar wind.Coordinated observations between SPORT and other spaceborne/ground-based facilities within the International Living With a Star(ILWS) framework can significantly enhance scientific output.SPORT is now competing for official selection and implementation during China's 13 th Five-Year Plan period of 2016-2020.XIONG Ming LIU Ying LIU Hao LI Baoquan ZHENG Jianhua ZHANG Cheng XIA Lidong ZHANG Hongxin RAO Wei CHEN Changya SUN Weiying WU Xia DENG Yuanyong HE Han JIANG Bo WANG Yuming WANG Chuanbing SHEN Chenglong ZHANG Haiying ZHANG Shenyi YANG Xuan SANG Peng WU Ji 2016空间科学学报2016,36,3:3
7Ultrathin salt-free polymer-in-ceramic electrolyte for solid-state sodium batteries显示文摘The practical energy density of solid-state batteries remains limited,partly because of the lack of a general method to fabricate thin membranes for solid-state electrolytes with high ionic conductivity and low area-specific resistance(ASR).Herein,we use an ultrahigh concentration of a ceramic ion conductor(Na_(3)SbS_(4))to build an ionconduction“highway”,and a polymer(polyethylene oxide,2 wt%)as a flexible host to prepare a polymer-inceramic ion-conducting membrane of approximately 40μm.Without the use of any salt(e.g.,NaPF_(6)),the resulting membrane exhibits a threefold increase in electronic ASR and a twofold decrease in ionic ASR compared with a pure ceramic counterpart.The activation energy for sodium-ion transport is only 190 meV in the membrane,similar to that in pure ceramic,suggesting ion transport predominantly occurs through a percolated network of ion-conducting ceramic particles.The salt-free design also provides an opportunity to suppress dendritic metal electrodeposits,according to a recently refined chemomechanical model of metal deposition.Our work suggests that salt is not always necessary in composite solid-state electrolytes,which broadens the choice of polymers to allow the optimization of other desired attributes,such as mechanical strength,chemical/electrochemical stability,and cost.Bin Tang Yibo Zhao Zhiyi Wang Shiwei Chen Yifan Wu Yuming Tseng Lujiang Li Yunlong Guo Zhen Zhou Shou-Hang Bo 2021eScience2021,1,2:2
8Risk stratification in symptomatic intracranial atherosclerotic disease with conventional vascular risk factors and cerebral haemodynamics显示文摘Background and purpose Symptomatic intracranial atherosclerotic stenosis(sICAS)is associated with a considerable risk of recurrent stroke despite contemporarily optimal medical treatment.Severity of luminal stenosis in sICAS and its haemodynamic significance quantified with computational fluid dynamics(CFD)models were associated with the risk of stroke recurrence.We aimed to develop and compare stroke risk prediction nomograms in sICAS,based on vascular risk factors and these metrics.Methods Patients with 50%-99%sICAS confirmed in CT angiography(CTA)were enrolled.Conventional vascular risk factors were collected.Severity of luminal stenosis in sICAS was dichotomised as moderate(50%-69%)and severe(70%-99%).Translesional pressure ratio(PR)and wall shear stress ratio(WSSR)were quantified via CTA-based CFD modelling;the haemodynamic status of sICAS was classified as normal(normal PR&WSSR),intermediate(otherwise)and abnormal(abnormal PR&WSSR).All patients received guideline-recommended medical treatment.We developed and compared performance of nomograms composed of these variables and independent predictors identified in multivariate logistic regression,in predicting the primary outcome,recurrent ischaemic stroke in the same territory(SIT)within 1 year.Results Among 245 sICAS patients,20(8.2%)had SIT.The D2H2A nomogram,incorporating diabetes,dyslipidaemia,haemodynamic status of sICAS,hypertension and age≥50 years,showed good calibration(P for Hosmer-Lemeshow test=0.560)and discrimination(C-statistic 0.73,95%CI 0.60 to 0.85).It also had better performance in risk reclassification and provided larger net benefits in decision curve analysis,compared with nomograms composed of conventional vascular risk factors only,and plus the severity of luminal stenosis in sICAS.Sensitivity analysis in patients with anterior-circulation sICAS showed similar results.Conclusions The D2H2A nomogram,incorporating conventional vascular risk factors and the haemodynamic significance of sICAS as assessed in CFD models,could be a useful tool to stratify sICAS patients for the risk of recurrent stroke under contemporarily optimal medical treatment.Xuan Tian Hui Fang Linfang Lan Hing Lung Ip Jill Abrigo Haipeng Liu Lina Zheng Florence S Y Fan Sze Ho Ma Bonaventure Ip Bo Song Yuming Xu Jingwei Li Bing Zhang Yun Xu Yannie O Y Soo Vincent Mok Ka Sing Wong Thomas W Leung Xinyi Leng 2023Stroke & Vascular Neurology2023,8,1:2
9Sliding Mode Control for Nonlinear Markovian Jump Systems Under Denial-of-Service Attacks显示文摘This paper investigates the sliding mode control(SMC) problem for a class of discrete-time nonlinear networked Markovian jump systems(MJSs) in the presence of probabilistic denial-of-service(Do S) attacks. The communication network via which the data is propagated is unsafe and the malicious adversary can attack the system during state feedback. By considering random Denial-of-Service attacks, a new sliding mode variable is designed, which takes into account the distribution information of the probabilistic attacks. Then, by resorting to Lyapunov theory and stochastic analysis methods, sufficient conditions are established for the existence of the desired sliding mode controller, guaranteeing both reachability of the designed sliding surface and stability of the resulting sliding motion.Finally, a simulation example is given to demonstrate the effectiveness of the proposed sliding mode control algorithm.Lei Liu Lifeng Ma Jie Zhang Yuming Bo 2020IEEE/CAA Journal of Automatica Sinica2020,7,6:2

11Global climate change and human health:Pathways and possible solutions显示文摘Global warming has been changing the planet’s climate pattern,leading to increasing frequency,intensity and duration of extreme weather events and natural disasters.These climate-changing events affect various health outcomes adversely through complicated pathways.This paper reviews the main signs of climate change so far,e.g.,suboptimal ambient temperature,sea-level rise and other conditions,and depicts the interactive pathways between different climate-changing events such as suboptimal temperature,wildfires,and floods with a broad range of health outcomes.Meanwhile,the modifying effect of socioeconomic,demographic and environmental factors on the pathways is summarised,such that the youth,elderly,females,poor and those living in coastal regions are particularly susceptible to climate change.Although Earth as a whole is expected to suffer from climate change,this review article discusses some potential benefits for certain regions,e.g.,a more liveable environment and sufficient food supply.Finally,we summarise certain mitigation and adaptation strategies against climate change and how these strategies may benefit human health in other ways.This review article provides a comprehensive and concise introduction of the pathways between climate change and human health and possible solutions,which may map directions for future research.Qi Zhao Pei Yu Rahini Mahendran Wenzhong Huang Yuan Gao Zhengyu Yang Tingting Ye Bo Wen Yao Wu Shanshan Li Yuming Guo 2022Eco-Environment & Health2022,1,2:1

15Non-pharmaceutical interventions for COVID-19 reduced the incidence of infectious diseases:a controlled interrupted time-series study显示文摘Background Non-pharmaceutical interventions(NPIs)have been implemented worldwide to suppress the spread of coronavirus disease 2019(COVID-19).However,few studies have evaluated the effect of NPIs on other infectious diseases and none has assessed the avoided disease burden associated with NPIs.We aimed to assess the effect of NPIs on the incidence of infectious diseases during the COVID-19 pandemic in 2020 and evaluate the health economic benefits related to the reduction in the incidence of infectious diseases.Methods Data on 10 notifiable infectious diseases across China during 2010–2020 were extracted from the China Information System for Disease Control and Prevention.A two-stage controlled interrupted time-series design with a quasi-Poisson regression model was used to examine the impact of NPIs on the incidence of infectious diseases.The analysis was first performed at the provincial-level administrative divisions(PLADs)level in China,then the PLAD-specific estimates were pooled using a random-effect meta-analysis.Results A total of 61,393,737 cases of 10 infectious diseases were identified.The implementation of NPIs was associated with 5.13 million(95%confidence interval[CI]3.45‒7.42)avoided cases and USD 1.77 billion(95%CI 1.18‒2.57)avoided hospital expenditures in 2020.There were 4.52 million(95%CI 3.00‒6.63)avoided cases for children and adolescents,corresponding to 88.2%of total avoided cases.The top leading cause of avoided burden attributable to NPIs was influenza[avoided percentage(AP):89.3%;95%CI 84.5‒92.6].Socioeconomic status and population density were effect modifiers.Conclusions NPIs for COVID-19 could effectively control the prevalence of infectious diseases,with patterns of risk varying by socioeconomic status.These findings have important implications for informing targeted strategies to prevent infectious diseases.Wenyi Zhang Yao Wu Bo Wen Yongming Zhang Yong Wang Wenwu Yin Shanhua Sun Xianyu Wei Hailong Sun Zhijie Zhang Shanshan Li Yuming Guo 2023Infectious Diseases of Poverty2023,12,2:1
16A low-energy ion spectrometer with half-space entrance for three-axis stabilized spacecraft显示文摘A low-energy ion spectrometer(LEIS) for use aboard three-axis stabilized spacecraft has been developed to measure ion energy per charge distribution in three-dimensional space with good energy-, angular-and temporal-resolutions. For the standard top-hat electrostatic analyzer used widely in space plasma detection, three-axis stabilized spacecraft makes it difficult to obtain complete coverage of all possible ion arrival directions. We have designed angular scanning deflectors supplementing to a cylindrically symmetric top-hat electrostatic analyzer to provide a half-space field of view as 360°×90°(–45°–+45°), and fabricated the LEIS flight model for detecting magnetospheric ions in geosynchronous orbit. The performance of this payload has been evaluated in detail by a series of simulation and environmental tests, and the payload has also been calibrated through laboratory experiments using a low-energy ion source. The results show that capabilities of the LEIS payload are in accordance with the requirements of a magnetospheric mission.HU RenXiang SHAN Xu YUAN GuangYuan WANG ShuWen ZHANG WeiHang QI Wei CAO Zhe LI YiRen CHEN ManMing YANG XiaoPing WANG Bo SHAO SiPei LI Feng ZHONG XiaoQing FAN Dan HAO XinJun FENG ChangQing SU ZhenPeng SHEN ChengLong LI Xin DAI GuYue QIU BingLin PAN ZongHao LIU Kai XU ChunKai LIU ShuBin AN Qi ZHANG TieLong WANG YuMing CHEN XiangJun 2019Science China(Technological Sciences)2019,62,6:1
17Morphological structures of poly(vinylidene fluoride)/montmorillonite nanocomposites显示文摘Poly(vinylidene fluoride) (PVDF)/montmorillonite (MMT) nanocomposites were prepared by melt blen- ding a kind of organically modified montmorillonite with PVDF. The morphological structures of the nanocomposites were studied using X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, and differential scanning calorimetry (DSC). The re- sults indicate that organically modified montmorillonites are in the form of intercalation, exfoliation, and fragments in the PVDF matrix. For the composites, the (001) peak position of MMT was found to shift to a lower angle in XRD patterns, and some MMT fragments could be observed under TEM. MMT loading was favorable to producing the piezoelectric β phase in the PVDF matrix and caused internal stress in α crystals. At the same time, the crystallinity and spherulite size of PVDF decreased with the MMT content. MMT induced β phase is stable even at high temperatures (160℃). For these changes in morphological structures, some possible explanations were proposed based on the experimental re- sults.SONG YuMing ZHAO ZhuDi YU WenXue LI Bo CHEN XinFang 2007Science China Chemistry2007,50,6:1
