| 1 | Effects of closing and reopening live poultry markets on the epidemic of human infection with avian influenza A virus显示文摘Live poultry markets(LPMs) are crucial places for human infection of influenza A(H7N9 virus).In Yangtze River Delta,LPMs were closed after the outbreak of human infection with avian influenza A(H7N9) virus,and then reopened when no case was found.Our purpose was to quantify the effect of LPMs' operations in this region on the transmission of influenza A(H7N9) virus.We obtained information about dates of symptom onset and locations for all human influenza A(H7N9) cases reported from Shanghai,Jiangsu and Zhejiang provinces by May 31,2014,and acquired dates of closures and reopening of LPMs from official media.A two-phase Bayesian model was fitted by Markov Chain Monte Carlo methods to process the spatial and temporal influence of human cases.A total of 235 cases of influenza A(H7N9) were confirmed in Shanghai,Jiangsu and Zhejiang by May 31,2014.Using these data,our analysis showed that,after LPM closures,the influenza A(H7N9) outbreak disappeared within two weeks in Shanghai,one week in Jiangsu,and one week in Zhejiang,respectively.Local authorities reopened LPMs when there was no outbreak of influenza A(H7N9),which did not lead to reemergence of human influenza A(H7N9).LPM closures were effective in controlling the H7N9 outbreak.Reopening of LPM in summer did not increase the risk of human infection with H7N9.Our findings showed that LPMs should be closed immediately in areas where the H7N9 virus is confirmed in LPM.When there is no outbreak of H7N9 virus,LPMs can be reopened to satisfy the Chinese traditional culture of buying live poultry.In the long term,local authorities should take a cautious attitude in permanent LPM closure. | Jian Lu Wendong Liu Rui Xia Qigang Dai Changjun Bao Fenyang Tang Yefei Zhu Qiao Wang | 2016 | The Journal of Biomedical Research2016，30，2： | 7 |
| 2 | Accretion in strong field gravity with eXTP显示文摘In this paper we describe the potential of the enhanced X-ray Timing and Polarimetry(eXTP) mission for studies related to accretion flows in the strong field gravity regime around both stellar-mass and supermassive black-holes. eXTP has the unique capability of using advanced 'spectral-timing-polarimetry' techniques to analyze the rapid variations with three orthogonal diagnostics of the flow and its geometry, yielding unprecedented insight into the inner accreting regions, the effects of strong field gravity on the material within them and the powerful outflows which are driven by the accretion process. | Alessandra De Rosa Phil Uttley LiJun Gou Yuan Liu Cosimo Bambi Didier Barret Tomaso Belloni Emanuele Berti Stefano Bianchi Ilaria Caiazzo Piergiorgio Casella Marco Feroci Valeria Ferrari Leonardo Gualtieri Jeremy Heyl Adam Ingram Vladimir Karas FangJun Lu Bin Luo Giorgio Matt Sara Motta Joseph Neilsen Paolo Pani Andrea Santangelo XinWen Shu JunFeng Wang Jian-Min Wang YongQuan Xue YuPeng Xu WeiMin Yuan YeFei Yuan Shuang-Nan Zhang Shu Zhang Ivan Agudo Lorenzo Amati Nils Andersson Cristina Baglio Pavel Bakala Altan Baykal Sudip Bhattacharyya Ignazio Bombaci NiccolóBucciantini Fiamma Capitanio Riccardo Ciolfi Wei K.Cui Filippo D'Ammando Thomas Dauser Melania Del Santo Barbara De Marco Tiziana Di Salvo Chris Done Michal Dovciak Andrew C.Fabian Maurizio Falanga Angelo Francesco Gambino Bruce Gendre Victoria Grinberg Alexander Heger Jeroen Homan Rosario Iaria JiaChen Jiang ChiChuan Jin Elmar Koerding Manu Linares Zhu Liu Thomas J.Maccarone Julien Malzac Antonios Manousakis Frédéric Marin Andea Marinucci Missagh Mehdipour Mariano Méndez Simone Migliari Cole Miller Giovanni Miniutti Emanuele Nardini Paul T.O'Brien Julian P.Osborne Pierre Olivier Petrucci Andrea Possenti Alessandro Riggio Jerome Rodriguez Andrea Sanna LiJing Shao Malgosia Sobolewska Eva Sramkova Abigail L.Stevens Holger Stiele Giulia Stratta Zdenek Stuchlik Jiri Svoboda Fabrizio Tamburini Thomas M.Tauris Francesco Tombesi Gabriel Torok Martin Urbanec Frederic Vincent QingWen Wu Feng Yuan Jean J.M.in't Zand Andrzej A.Zdziarski XinLin Zhou | 2019 | Science China(Physics,Mechanics & Astronomy)2019，62，2： | 1 |
| 3 | A Novel Retrograde AAV Variant for Functional Manipulation of Cortical Projection Neurons in Mice and Monkeys显示文摘Retrograde adeno-associated viruses(AAVs)are capable of infecting the axons of projection neurons and serve as a powerful tool for the anatomical and functional characterization of neural networks.However,few retro-grade AAV capsids have been shown to offer access to cor-tical projection neurons across different species and enable the manipulation of neural function in non-human primates(NHPs).Here,we report the development of a novel retro-grade AAV capsid,AAV-DJ8R,which efficiently labeled cortical projection neurons after local administration into the striatum of mice and macaques.In addition,intrastriatally injected AAV-DJ8R mediated opsin expression in the mouse motor cortex and induced robust behavioral alterations.Moreover,AAV-DJ8R markedly increased motor cortical neuron firing upon optogenetic light stimulation after viral delivery into the macaque putamen.These data demonstrate the usefulness of AAV-DJ8R as an efficient retrograde tracer for cortical projection neurons in rodents and NHPs and indicate its suitability for use in conducting functional interrogations. | Yefei Chen Jingyi Wang Jing Liu Jianbang Lin Yunping Lin Jinyao Nie Qi Yue Chunshan Deng Xiaofei Qi Yuantao Li Ji Dai Zhonghua Lu | 2024 | Neuroscience Bulletin2024，40，1： | 0 |
| 4 | Non-specific phospholipase C4 hydrolyzes phosphosphingolipids and phosphoglycerolipids and promotes rapeseed growth and yield显示文摘Phosphorus is a major nutrient vital for plant growth and development,with a substantial amount of cellular phosphorus being used for the biosynthesis of membrane phospholipids.Here,we report that NON-SPECIFIC PHOSPHOLIPASE C4(NPC4)in rapeseed(Brassica napus)releases phosphate from phospholipids to promote growth and seed yield,as plants with altered NPC4 levels showed significant changes in seed production under different phosphate conditions.Clustered regularly interspaced short palindromic repeat(CRISPR)/CRISPR-associated nuclease 9(Cas9)-mediated knockout of Bna NPC4 led to elevated accumulation of phospholipids and decreased growth,whereas overexpression(OE)of Bna NPC4resulted in lower phospholipid contents and increased plant growth and seed production.We demonstrate that Bna NPC4 hydrolyzes phosphosphingolipids and phosphoglycerolipids in vitro,and plants with altered Bna NPC4 function displayed changes in their sphingolipid and glycerolipid contents in roots,with a greater change in glycerolipids than sphingolipids in leaves,particularly under phosphate deficiency conditions.In addition,Bna NPC4-OE plants led to the upregulation of genes involved in lipid metabolism,phosphate release,and phosphate transport and an increase in free inorganic phosphate in leaves.These results indicate that Bna NPC4 hydrolyzes phosphosphingolipids and phosphoglycerolipids in rapeseed to enhance phosphate release from membrane phospholipids and promote growth and seed production. | Bao Yang Jianwu Li Jiayu Yan Ke Zhang Zhewen Ouyang Yefei Lu Huili Wei Qing Li Xuan Yao Shaoping Lu Yueyun Hong Xuemin Wang Liang Guo | 2023 | Journal of Integrative Plant Biology2023，65，11： | 0 |
| 5 | Digestive tract reconstruction in pancreaticoduodenectomy in University Hospitals of China: a national questionnaire survey显示文摘Background Pancreaticoduodenectomy(PD)has been widely applied in general hospitals in China;however,there is still a lack of unified standards for each surgical technique and procedure.This survey is intended to investigate the current status of digestive tract reconstruction after PD in university hospitals in China.Method A cross-sectional survey was conducted among the members of the Young Elite Pancreatic Surgery Club of China by using the Questionnaire for Digestive Tract Reconstruction after Pancreaticoduodenectomy.The questionnaire was disseminated and collected by point-to-point communication via WeChat public platforms.Results A total of 73 valid questionnaires were returned from 65 university hospitals in 28 provincial divisions of China's Mainland.The respondents who performed PD surgery with an annual volume of over 100 cases accounted for 63%.Generally,laparoscopic PD was performed less often than open PD.Child and Whipple reconstructions accounted for 70%and 26%,respectively.The sequence of pancreatoenteric,biliary-enteric,and gastrointestinal reconstruction accounted for 84%of cases.In pancreatoenteric anastomosis,double-layer anastomosis is the most commonly employed type,accounting for approximately 67%,while single-layer anastomosis accounts for 30%.Of the double-layer anastomoses,duct-to-mucosa/dunking(94%/4%)PJ was performed with duct-mucosa using the Blumgart method(39%)and Cattel-Warren(29%),with continuous/interrupted sutures in the inner layer(69%/31%)and continuous/interrupted sutures in the outer layer(53%/23%).In single-layer anastomosis,continuous/interrupted sutures accounted for 41%/45%.In hepatojejunostomy,single-layer/double-layer suture accounted for 79%/4%,and continuous/interrupted suture accounted for 75%/9%.Forty-six percent of the responding units had not applied double-layer biliary-intestinal anastomosis in the last 3 years,75%of the responding surgeons chose the anastomosis method according to bile duct diameter,with absorbable/non-absorbable suture accounting for 86%/12%.PD/pylorus-preserving PD accounted for 79%/11%of GJ cases,the distance between GJ and HJ<30 cm,30-50 cm and>50 cm were 11%,75%,and 14%,respectively.Antecolic/retrocolic GJ accounted for 71%/23%of cases.Twenty-two percent of GJ cases employed Braun anastomosis,while 55%and 19%of GJ cases used linear cutting staplers/tube-type staplers,respectively;60%/14%were reinforced/not reinforced via manual suturing after stapler anastomosis.Manual anastomosis in GJ surgery employed absorbable/non-absorbable sutures(91%/9%).Significant differences in reconstruction techniques were detected between different volumes of PD procedures(<100/year and>100/year),regions with different economic development levels,and between north and south China.Conclusion Digestive tract reconstruction following PD exists heterogeneity in Chinese university hospitals.Corresponding prospective clinical studies are needed to determine the consensus on pancreatic surgery that meets the clinical reality in China. | Jishu Wei Qiang Xu Yuhua Zhang Jiabin Jin Xiaodong Tian Qiaofei Liu Zipeng Lu Zheng Wang Shanmiao Gou Song Gao Xianlin Han Yefei Rong Niandong Ji Ye Lin Guolin Li Shi Chen Feng Cao Hua Chen Wenming Wu Yupei Zhao the Young Elite Pancreatic Surgery Club of China | 2022 | Journal of Pancreatology2022，5，3： | 0 |
