| 1 | Evolution of the novel coronavirus from the ongoing Wuhan outbreak and modeling of its spike protein for risk of human transmission显示文摘Dear Editor,The occurrence of concentrated pneumonia cases in Wuhan city,Hubei province of China was first reported on December 30,2019 by the Wuhan Municipal Health Commission(WHO,2020).The pneumonia cases were found to be linked to a large seafood and animal market in Wuhan,and measures for sanitation and disinfection were taken swiftly by the local government agency.The Centers for Disease Control and Prevention(CDC)and Chinese health authorities later determined and announced that a novel coronavirus(CoV),denoted as 2019-nCoV,had caused the pneumonia outbreak in Wuhan city(CDC,2020).Scientists from multiple groups had obtained the virus samples from hospitalized patients(Normile,2020).The isolated viruses were morphologically identical when observed under electron microscopy. | Xintian Xu Ping Chen Jingfang Wang Jiannan Feng Hui Zhou Xuan Li Wu Zhong Pei Hao | 2020 | Science China(Life Sciences)2020，63，3： | 737 |
| 2 | Transmission routes of 2019-nCoV and controlsin dental practice显示文摘A novel β-coronavirus(2019-nCoV) caused severe and even fatal pneumonia explored in a seafood market of Wuhan city, Hubei province, China, and rapidly spread to other provinces of China and other countries. The 2019-nCoV was different from SARS-Co V,but shared the same host receptor the human angiotensin-converting enzyme 2(ACE2). The natural host of 2019-nCoV may be the bat Rhinolophus affinis as 2019-nCoV showed 96.2% of whole-genome identity to Bat Co V Ra TG13. The person-to-person transmission routes of 2019-nCoV included direct transmission, such as cough, sneeze, droplet inhalation transmission, and contact transmission, such as the contact with oral, nasal, and eye mucous membranes. 2019-nCoV can also be transmitted through the saliva, and the fecal–oral routes may also be a potential person-to-person transmission route. The participants in dental practice expose to tremendous risk of 2019-nCoV infection due to the face-to-face communication and the exposure to saliva, blood, and other body fluids, and the handling of sharp instruments. Dental professionals play great roles in preventing the transmission of2019-nCoV. Here we recommend the infection control measures during dental practice to block the person-to-person transmission routes in dental clinics and hospitals. | Xian Peng Xin Xu Yuqing Li Lei Cheng Xuedong Zhou Biao Ren | 2020 | International Journal of Oral Science2020，12，1： | 29 |

| 4 | Toxicity of cadmium and its competition with mineral nutrients for uptake by plants:A review显示文摘Cadmium(Cd)is a toxic heavy metal occurring in the environment naturally and is also generated through various anthropogenic sources and acts as a pollutant.Human health is affected by Cd pollution in farmland soils because food is the main source of Cd intake in the non-smoking population.For crops,Cd toxicity may result from a disturbance in uptake and translocation of mineral nutrients and disturbance in plant metabolism,inhibiting plant growth and development.However,plants have Cd tolerance mechanisms,including restricted Cd uptake,decreased Cd root-to-shoot translocation,enhanced antioxidant enzyme activities,and increased production of phytochelatins.Furthermore,optimal supply of mineral nutrients is one of the strategies to alleviate the damaging effects of Cd on plants and to avoid its entry into the food chain.The emerging molecular knowledge contributes to understanding Cd uptake,translocation,and remobilization in plants.In this review,Cd toxicity and tolerance mechanisms,agricultural practices to minimize Cd accumulation,Cd competition with essential elements(calcium,copper,iron,zinc,and manganese),and genes associated with Cd uptake are discussed in detail,especially regarding how these mineral nutrients and genes play a role in decreasing Cd uptake and accumulation in crop plants. | Shiyu QIN Hongen LIU Zhaojun NIE Zed RENGEL Wei GAO Chang LI Peng ZHAO | 2020 | Pedosphere2020，30，2： | 20 |

| 6 | How do machine learning techniques help in increasing accuracy of landslide susceptibility maps?显示文摘Landslides are abundant in mountainous regions.They are responsible for substantial damages and losses in those areas.The A1 Highway,which is an important road in Algeria,was sometimes constructed in mountainous and/or semi-mountainous areas.Previous studies of landslide susceptibility mapping conducted near this road using statistical and expert methods have yielded ordinary results.In this research,we are interested in how do machine learning techniques help in increasing accuracy of landslide susceptibility maps in the vicinity of the A1 Highway corridor.To do this,an important section at Ain Bouziane(NE,Algeria) is chosen as a case study to evaluate the landslide susceptibility using three different machine learning methods,namely,random forest(RF),support vector machine(SVM),and boosted regression tree(BRT).First,an inventory map and nine input factors were prepared for landslide susceptibility mapping(LSM) analyses.The three models were constructed to find the most susceptible areas to this phenomenon.The results were assessed by calculating the receiver operating characteristic(ROC) curve,the standard error(Std.error),and the confidence interval(CI) at 95%.The RF model reached the highest predictive accuracy(AUC=97.2%) comparatively to the other models.The outcomes of this research proved that the obtained machine learning models had the ability to predict future landslide locations in this important road section.In addition,their application gives an improvement of the accuracy of LSMs near the road corridor.The machine learning models may become an important prediction tool that will identify landslide alleviation actions. | Yacine Achour Hamid Reza Pourghasemi | 2020 | Geoscience Frontiers2020，11，3： | 11 |
| 7 | RILL EROSION PROCESS ON STEEP SLOPE LAND OF THE LOESS PLATEAU显示文摘Rill erosion processes and principle of preventing rill erosion of different applied measures are studied by rainfall simulation and field investigation. Research results show that rill erosion processes can be schematically divided into five stages, that is, concentrated flow forming process; little waterfalls in the concentrated flow forming Process; little waterfalls developing into rill head cut process; rill head cuts developing to form discontinuous rill process and discontinuous rills connecting to form continuous rill process. Rill head cuts backward erosion, rill wall collapsing and runoff washing rill bed are the main patterns of rill development. The relevant equation between critical runoff volume of occurring rill erosion and slope degree can be expressed as follows: Q = 76. 10 - 2. 10J. And relevant equation between critical slope length of occurrence Of rill erosion and slope degree is parabolic with a minimum-value. In addition, influence of rill erosion development on slope runoff and soil erosion, benefits and principle of reducing rill erosion amount of mulch, non-tillage system and remained residue, strip alternation of grass and crop, horizontal ditch are also studied. | ZHENG Fenli and TANG Keli (1 The English text has been altered and edited by Dr. DING Lianzhen 2 Engineer, National Key Laboratory of Soil Erosion and Dryland Farming on Loess Plateau, Chinese Academy of Sciences and institute of Soil and Water Conservati | 1997 | International Journal of Sediment Research1997，12，1： | 9 |

| 10 | Surgical outcome and patient satisfaction after Z-epicanthoplasty and blepharoplasty显示文摘AIM: To evaluate surgical outcomes of modified Z-epicanthoplasty with blepharoplasty that we previously reported from the patient's perspective using patient-reported outcome measures(PROMs) and patient satisfaction scores.METHODS: A total of patients(n=180) who underwent the surgery between January 2013 and June 2016 were randomly selected. Standardized patient satisfaction forms(total score, 40) and validated PROMs questionnaires(total score, 12) were sent to patients for completion. PROMs assesses the severity of scarring, pain and asymmetry, as well as functional and appearance issues.RESULTS: All patients were female, ranging from 18 to 35 years old(mean=24). The response rate was 73.3%(n=132). The majority of patients reported good or excellent outcomes based on PROM analysis. Patients reported minimum or non-visible scarring at both the double eyelid surgical scar(85.6%) and the inner canthus(80.3%). Issues concerning function and appearance were minimal as 80.3% reported satisfaction with both domains. Notably, the majority of patients reported either a high or very high satisfaction rate to yield a mean score of 104 out of 120(P<0.05).CONCLUSION: Integration of our modified Z-epicanthoplasty with blepharoplasty produces good outcomes based on PROM results, which shows a positive linear relationship with patient satisfaction scores. | Jing-Yi Zhao Xiao-Shuang Guo Guo-Dong Song Xian-Lei Zong Xiao-Nan Yang Le Du Chen-Zhi Lai Zuo-Liang Qi Xiao-Lei Jin | 2018 | International Journal of Ophthalmology(English edition)2018，11，12： | 7 |

| 12 | The pig as a preclinical traumatic brain injury model:current models,functional outcome measures,and translational detection strategies显示文摘Traumatic brain injury(TBI) is a major contributor of long-term disability and a leading cause of death worldwide. A series of secondary injury cascades can contribute to cell death, tissue loss, and ultimately to the development of functional impairments. However, there are currently no effective therapeutic interventions that improve brain outcomes following TBI. As a result, a number of experimental TBI models have been developed to recapitulate TBI injury mechanisms and to test the efficacy of potential therapeutics. The pig model has recently come to the forefront as the pig brain is closer in size, structure, and composition to the human brain compared to traditional rodent models, making it an ideal large animal model to study TBI pathophysiology and functional outcomes. This review will focus on the shared characteristics between humans and pigs that make them ideal for modeling TBI and will review the three most common pig TBI models–the diffuse axonal injury, the controlled cortical impact, and the fluid percussion models. It will also review current advances in functional outcome assessment measures and other non-invasive, translational TBI detection and measurement tools like biomarker analysis and magnetic resonance imaging. The use of pigs as TBI models and the continued development and improvement of translational assessment modalities have made significant contributions to unraveling the complex cascade of TBI sequela and provide an important means to study potential clinically relevant therapeutic interventions. | Holly A.Kinder Emily W.Baker Franklin D.West | 2019 | Neural Regeneration Research2019，14，3： | 7 |
| 13 | Endoscopic submucosal dissection for early esophageal neoplasms using the stag beetle knife显示文摘AIM To determine short-and long-term outcomes of endoscopic submucosal dissection(ESD) using the stag beetle(SB) knife, a scissor-shaped device.METHODS Seventy consecutive patients with 96 early esophageal neoplasms, who underwent ESD using a SB knife at Kure Medical Center and Chugoku Cancer Center, Japan, between April 2010 and August 2016, were retrospectively evaluated. Clinicopathological characteristics of lesions and procedural adverse events were assessed. Therapeutic success was evaluated on the basis of en bloc, histologically complete, and curative or non-curative resection rates. Overall and tumor-specific survival, local or distant recurrence, and 3-and 5-year cumulative overall metachronous cancer rates were also assessed.RESULTS Eligible patients had dysplasia/intraepithelial neoplasia(22%) or early cancers(squamous cell carcinoma, 78%). The median procedural time was 60 min and on average, the lesions measured 24 mm in diameter, yielding 33-mm tissue defects. The en bloc resection rate was 100%, with 95% and 81% of dissections deemed histologically complete and curative, respectively. All procedures were completed without accidental incisions/perforations or delayed bleeding. During follow-up(mean, 35 ± 23 mo), no local recurrences or metastases were observed. The 3-and 5-year survival rates were 83% and 70%, respectively, with corresponding rates of 85% and 75% for curative resections and 74% and 49% for noncurative resections. The 3-and 5-year cumulative rates of metachronous cancer in the patients with curative resections were 14% and 26%, respectively.CONCLUSION ESD procedures using the SB knife are feasible, safe, and effective for treating early esophageal neoplasms, yielding favorable short-and long-term outcomes. | Toshio Kuwai Toshiki Yamaguchi Hiroki Imagawa Ryoichi Miura Yuki Sumida Takeshi Takasago Yuki Miyasako Tomoyuki Nishimura Sumio Iio Atsushi Yamaguchi Hirotaka Kouno Hiroshi Kohno Sauid Ishaq | 2018 | World Journal of Gastroenterology2018，24，15： | 7 |
| 14 | 采取系统方案抗击全球新型冠状病毒肺炎显示文摘The novel coronavirus disease,named COVID-19,emerged in China in December 2019[1].In the early phases of the outbreak in Wuhan City,timely and effective control measures to prevent COVID-19 spread were delayed for several reasons,including lack of knowledge and vigilance regarding the new disease,insufficient or inefficient detection tools.However,the adoption by Chinese authorities of a systematic approach to the disease has resulted in the number of recoveries per day,since February 18th,2020,exceeding the number of newly confirmed cases,and the cumulative number of patients cured exceeded the remaining confirmed cases on February 28th,2020(http://www.nhc.gov.cn/xcs/yqtb/list_gzbd). | 赵文武 张军泽 Michael E.Meadows 刘焱序 华廷 傅伯杰 | 2020 | Science Bulletin2020，65，11： | 6 |
| 15 | The Risk and Prevention of Novel Coronavirus Pneumonia Infections Among Inpatients in Psychiatric Hospitals显示文摘Dear Editor,Since the middle of December 2019,human-to-human transmission of novel coronavirus pneumonia(NCP,also called COVID-19)has occurred among close contacts[1].After the outbreak on January 21,2020,it was swiftly included among the Class B infectious diseases stipulated in the Law of the People’s Republic of China on the Prevention and Control of Infectious Diseases,and measures for prevention and control of Class A infectious diseases were adopted.At 21:27 on February 12,2020,the China News Network updated information to include epidemic data from the National Health Commission and official channels in Hong Kong,Macao,and Taiwan regions:the highest death rate was in Wuhan City(Table 1).Overload of inpatients at hospitals may play a negative role in the overall therapeutic effect and contribute to the death rate. | Yuncheng Zhu Liangliang Chen Haifeng Ji Maomao Xi Yiru Fang Yi Li | 2020 | Neuroscience Bulletin2020，36，3： | 6 |

| 17 | Spatio-temporal evolution of Beijing 2003 SARS epidemic显示文摘Studying spatio-temporal evolution of epidemics can uncover important aspects of interaction among people, infectious diseases, and the environment, providing useful insights and modeling support to facilitate public health response and possibly prevention measures. This paper presents an empirical spatio-temporal analysis of epidemiological data concerning 2321 SARS-infected patients in Beijing in 2003. We mapped the SARS morbidity data with the spatial data resolution at the level of street and township. Two smoothing methods, Bayesian adjustment and spatial smoothing, were applied to identify the spatial risks and spatial transmission trends. Furthermore, we explored various spatial patterns and spatio-temporal evolution of Beijing 2003 SARS epidemic using spatial statistics such as Moran’s I and LISA. Part of this study is targeted at evaluating the effectiveness of public health control measures implemented during the SARS epidemic. The main findings are as follows. (1) The diffusion speed of SARS in the northwest-southeast direction is weaker than that in northeast-southwest direction. (2) SARS’s spread risk is positively spatially associated and the strength of this spatial association has experienced changes from weak to strong and then back to weak during the lifetime of the Beijing SARS epidemic. (3) Two spatial clusters of disease cases are identified: one in the city center and the other in the eastern suburban area. These two clusters followed different evolutionary paths but interacted with each other as well. (4) Although the government missed the opportunity to contain the early outbreak of SARS in March 2003, the response strategies implemented after the mid of April were effective. These response measures not only controlled the growth of the disease cases, but also mitigated the spatial diffusion. | CAO ZhiDong ZENG DaJun ZHENG XiaoLong WANG QuanYi WANG FeiYue WANG JinFeng WANG XiaoLi | 2010 | Science China Earth Sciences2010，53，7： | 5 |

| 20 | Outcomes in randomized controlled trials of exercise interventions in solid organ transplant显示文摘AIM To identify the outcome measures that have been used in randomized controlled trials(RCTs) of exercise training in solid organ transplant(SOT) recipients and to link these outcomes to the International Classification of Functioning, Disability and Health(ICF) framework.METHODS Electronic literature searches of MEDLINE, EMBASE, CINAHL, Cochrane, Scopus, and Web of Science were performed. We sought RCTs that investigated the effect of exercise training in SOT recipients. Reference lists of all eligible publications were searched for other appropriate studies not identified by the electronic search. A complete list of outcome measures used in the RCTs was generated and each of these was linked to an ICF category.RESULTS Four hundred and thirteen articles were retrieved, of which 35 met our inclusion criteria. The studies included were designed to compare the effects of exercise training programs to usual care or to another exercise training program and reported on recipients of heart(n = 21), kidney(n = 9), lung(n = 3) or liver(n = 2) transplant. Of the 126 outcome measures identified, 62 were used as primary outcome measures. The most commonly occurring primary outcomes were aerobic capacity using the peak VO2(n = 13), quality of life using the shortform-36(n = 8), and muscle strength(n = 7). Theseoutcome measures were linked to 113 ICF categories and the majority of outcomes fall into the body function domain(n = 93). CONCLUSION There is little standardization in outcome measures used in RCTs of exercise interventions in SOT recipients. The ICF framework can be used to select a core set of outcomes that cross all domains of ICF and that would be appropriate to all SOT recipients. | Tania Janaudis-Ferreira Sunita Mathur Stacey Konidis Catherine M Tansey Cecile Beaurepaire | 2016 | World Journal of Transplantation2016，6，4： | 4 |
