| 2 | Poor performance of the modified early warning score for predicting mortality in critically ill patients presenting to an emergency department显示文摘BACKGROUND:This study was undertaken to validate the use of the modified early warning score(MEWS) as a predictor of patient mortality and intensive care unit(ICU)/ high dependency(HD)admission in an Asian population.METHODS:The MEWS was applied to a retrospective cohort of 1 024 critically ill patients presenting to a large Asian tertiary emergency department(ED) between November 2006 and December2007.Individual MEWS was calculated based on vital signs parameters on arrival at ED.Outcomes of mortality and ICU/HD admission were obtained from hospital records.The ability of the composite MEWS and its individual components to predict mortality within 30 days from ED visit was assessed.Sensitivity,specificity,positive and negative predictive values were derived and compared with values from other cohorts.A MEWS of ≥4 was chosen as the cut-off value for poor prognosis based on previous studies.RESULTS:A total of 311(30.4%) critically ill patients were presented with a MEWS ≥4.Their mean age was 61.4 years(SD 18.1) with a male to female ratio of 1.10.Of the 311 patients,53(17%)died within 30 days,64(20.6%) were admitted to ICU and 86(27.7%) were admitted to HD.The area under the receiver operating characteristic curve was 0.71 with a sensitivity of 53.0%and a specificity of 72.1%in addition to a positive predictive value(PPV) of 17.0%and a negative predictive value(NPV)of 93.4%(MEWS cut-off of ≥4) for predicting mortality.CONCLUSION:The composite MEWS did not perform well in predicting poor patient outcomes for critically ill patients presenting to an ED. | Le Onn Ho Huihua Li Nur Shahidah Zhi Xiong Koh Papia Sultana Marcus Eng Hock Ong | 2013 | World Journal of Emergency Medicine2013，4，4： | 12 |
| 3 | Mitogenomic phylogeny of the Asian colobine genus Trachypithecus with special focus on Trachypithecus phayrei(Blyth, 1847) and description of a new species显示文摘Trachypithecus,which currently contains 20 species divided into four groups,is the most speciose and geographically dispersed genus among Asian colobines.Despite several morphological and molecular studies,however,its evolutionary history and phylogeography remain poorly understood.Phayre’s langur(Trachypithecus phayrei) is one of the most widespread members of the genus,but details on its actual distribution and intraspecific taxonomy are limited and controversial.Thus,to elucidate the evolutionary history of Trachypithecus and to clarify the intraspecific taxonomy and distribution of T.phayrei,we sequenced 41 mitochondrial genomes from georeferenced fecal samples and museum specimens,including two holotypes.Phylogenetic analyses revealed a robustly supported phylogeny of Trachypithecus,suggesting that the T.pileatus group branched first,followed by the T.francoisi group,and the T.cristatus and T.obscurus groups most recently.The four species groups diverged from each other 4.5-3.1 million years ago(Ma),while speciation events within these groups occurred much more recently(1.6-0.3 Ma).Within T.phayrei,we found three clades that diverged 1.0-0.9 Ma,indicating the existence of three rather than two taxa.Following the phylogenetic species concept and based on genetic,morphological,and ecological differences,we elevate the T.phayrei subspecies to species level,describe a new species from central Myanmar,and refine the distribution of the three taxa.Overall,our study highlights the importance of museum specimens and provides new insights not only into the evolutionary history of T.phayrei but the entire Trachypithecus genus as well. | Christian Roos Kristofer MHelgen Roberto Portela Miguez Naw May Lay Thant Ngwe Lwin Aung Ko Lin Aung Lin Khin Mar Yi Paing Soe Zin Mar Hein Margaret Nyein Nyein Myint Tanvir Ahmed Dilip Chetry Melina Urh EGrace Veatch Neil Duncan Pepijn Kamminga Marcus AHChua Lu Yao Christian Matauschek Dirk Meyer Zhi-Jin Liu Ming Li Tilo Nadler Peng-Fei Fan Le Khac Quyet Michael Hofreiter Dietmar Zinner Frank Momberg | 2020 | Zoological Research2020，41，6： | 5 |

| 6 | Effects of a phase transition on two-pion interferometry in heavy ion collisions at √SNN=2.4-7.7 GeV显示文摘Hanbury-Brown-Twiss(HBT) correlations for charged pions in central Au+Au collisions at √SNN=2.4-7.7 GeV(corresponding to beam kinetic energies in the fixed target frame from Elab=1.23 to 30 GeV/nucleon) are calculated using the ultra-relativistic quantum molecular dynamics model with different equations of state(EoSs).The effects of a phase transition at high baryon densities are clearly observed in the explored HBT parameters.The results show that the available data on the HBT radii,RO/RSand R^(2)_(O)-R^(2)_(S),in the investigated energy region favor a relatively stiff EoS at low beam energies,which then turns into a soft EoS at high collision energies consistent with astrophysical constraints on the high-density EoS of quantum chromodynamics(QCD).The specific effects of two different phase transition scenarios on RO/RSand R^(2)_(O)-R^(2)_(S)are investigated.A phase transition with a significant softening of the EoS below four times the nuclear saturation density can be excluded using HBT data.Our results highlight that the pion’s RO/RSand R^(2)_(O)-R^(2)_(S)are sensitive to the stiffness of the EoS and can be used to constrain and understand the QCD EoS in a high baryon density region. | Pengcheng Li Jan Steinheimer Tom Reichert Apiwit Kittiratpattana Marcus Bleicher Qingfeng Li | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，3： | 3 |
| 7 | FRAME: femtosecond videography for atomic and molecular dynamics显示文摘Many important scientific questions in physics,chemistry and biology require effective methodologies to spectroscopically probe ultrafast intra-and inter-atomic/molecular dynamics.However,current methods that extend into the femtosecond regime are capable of only point measurements or single-snapshot visualizations and thus lack the capability to perform ultrafast spectroscopic videography of dynamic single events.Here we present a laser-probe-based method that enables two-dimensional videography at ultrafast timescales(femtosecond and shorter)of single,non-repetitive events.The method is based on superimposing a structural code onto the illumination to encrypt a single event,which is then deciphered in a post-processing step.This coding strategy enables laser probing with arbitrary wavelengths/bandwidths to collect signals with indiscriminate spectral information,thus allowing for ultrafast videography with full spectroscopic capability.To demonstrate the high temporal resolution of our method,we present videography of light propagation with record high 200 femtosecond temporal resolution.The method is widely applicable for studying a multitude of dynamical processes in physics,chemistry and biology over a wide range of time scales.Because the minimum frame separation(temporal resolution)is dictated by only the laser pulse duration,attosecondlaser technology may further increase video rates by several orders of magnitude. | Andreas Ehn Joakim Bood Zheming Li Edouard Berrocal Marcus Aldén Elias Kristensson | 2017 | Light(Science & Applications)2017，6，1： | 2 |
| 8 | Comparison of two emergency medical services in Beijing and Hong Kong, China显示文摘To Out-of-hospital cardiac arrest (OHCA) is a major issue in emergency care worldwide. The incidence of OHCA is estimated to be 50 to 60 per 100,000 persons globally.Despite advances in treatment and technology, survival following OHCA remains low. There are multiple factors affecting the survival outcome. The type of emergency medical service (EMS) system is likely to be one of them. In Asia, the EMS structure and its service capability in terms of dispatch, airway management, and medications vary widely between communities. This study aimed to evaluate the survival outcomes of OHCA in Beijing and Hong Kong (HK), China and the effect of the type of EMS system on the survival outcomes for patients with OHCA. | Fei Shao Kit-Ling Fan Colin Robertson Marcus Ong Nan Liu Ling-Pong Leung Reynold Leung Chun-Sheng Li | 2019 | Chinese Medical Journal2019，，11： | 2 |
| 9 | RhizoVision Crown:An Integrated Hardware and Software Platform for Root Crown Phenotyping显示文摘Root crown phenotyping measures the top portion of crop root systems and can be used for marker-assisted breeding,genetic mapping,and understanding how roots influence soil resource acquisition.Several imaging protocols and image analysis programs exist,but they are not optimized for high-throughput,repeatable,and robust root crown phenotyping.The RhizoVision Crown platform integrates an imaging unit,image capture software,and image analysis software that are optimized for reliable extraction of measurements from large numbers of root crowns.The hardware platform utilizes a backlight and a monochrome machine vision camera to capture root crown silhouettes.The RhizoVision Imager and RhizoVision Analyzer are free,open-source software that streamline image capture and image analysis with intuitive graphical user interfaces.The RhizoVision Analyzer was physically validated using copper wire,and features were extensively validated using 10,464 groundtruth simulated images of dicot and monocot root systems.This platform was then used to phenotype soybean and wheat root crowns.A total of 2,799 soybean(Glycine max)root crowns of 187 lines and 1,753 wheat(Triticum aestivum)root crowns of 186 lines were phenotyped.Principal component analysis indicated similar correlations among features in both species.The maximum heritability was 0.74 in soybean and 0.22 in wheat,indicating that differences in species and populations need to be considered.The integrated RhizoVision Crown platform facilitates high-throughput phenotyping of crop root crowns and sets a standard by which open plant phenotyping platforms can be benchmarked. | Anand Seethepalli Haichao Guo Xiuwei Liu Marcus Griffiths Hussien Almtarfi Zenglu Li Shuyu Liu Alina Zare Felix B.Fritschi Elison B.Blancaflor Xue-Feng Ma Larry M.York | 2020 | Plant Phenomics2020，2，1： | 2 |

| 20 | Pay-it-forward gonorrhea and chlamydia testing among men who have sex with men in China:a study protocol for a three-arm cluster randomized controlled trial显示文摘Background:Gonorrhea and chlamydia testing rates are poor among Chinese men who have sex with men(MSM).A quasi-experimental study suggested that a pay-it-forward strategy increased dual gonorrhea/chlamydia testing among MSM.Pay-it-forward offers an individual a gift(e.g.,a free test)and then asks the same person if they would like to give a gift to another person.This article reports the protocol of a randomized controlled trial to evaluate dual gonorrhea/chlamydia test uptake and other outcomes among MSM in three arms-a pay-it-forward arm,a pay-what-you-want arm,and a standard of care arm.Methods:Three hundred MSM will be recruited at three HIV testing sites in Guangzhou and Beijing.Testing sites include two hospital-based MSM sexually transmitted diseases clinics and one MSM community-based organization.Eligible participants will be born biologically male,aged 16 years or older,reporting previous anal sex with another man,having never participated in the pay-it-forward program,without previous gonorrhea and chlamydia testing in the past 12 months,and residing in China.Following a cluster randomized design,every cluster of ten participants will be randomly allocated into one of three arms:(1)a pay-it-forward arm in which men are offered free gonorrhea and chlamydia testing and then asked whether they would like to donate('pay it forward')toward testing for future testers;(2)a pay-what-you-want arm in which men are offered free testing and told to decide how much to pay after receiving the test;(3)a standard of care arm in which men can pay the full price for dual gonorrhoea and chlamydia testing.The primary outcome is dual gonorrhoea/chlamydia testing as verified by administrative records.Secondary outcomes include incremental cost per test,incremental cost per diagnosis,community connectedness,and social cohesion.Primary outcome will be calculated for each arm using intention-to-treat and compared using one-sided 95%confidence intervals with a margin of 20%increase defined as superiority.Discussion:This study will examine the pay-it-forward strategy in comparison to the standard of care in improving test uptake for gonorrhea and chlamydia.We will leverage the cluster randomized controlled trial to provide scientific evidence on the potential effect of pay-it-forward.Findings from this study will shed light on novel intervention methods for increasing preventive health service utilization and innovate ways to finance it among communities.Trial registration:ClinicalTrials.gov,NCT03741725.Registered on 12 November 2018. | Tiange P.Zhang Fan Yang Weiming Tang Marcus Alexander Laura Forastiere Navin Kumar Katherine Li Fei Zou Ligang Yang Guodong Mi Yehua Wang Wenting Huang Amy Lee Weizan Zhu Peter Vickerman Dan Wu Bin Yang Nicholas A.Christakis Joseph D.Tucker | 2019 | Infectious Diseases of Poverty2019，8，4： | 1 |
