1Clinical and biochemical indexes from 2019-nCoV infected patients linked to viral loads and lung injury显示文摘The outbreak of the 2019-nCoV infection began in December 2019 in Wuhan,Hubei province,and rapidly spread to many provinces in China as well as other countries.Here we report the epidemiological,clinical,laboratory,and radiological characteristics,as well as potential biomarkers for predicting disease severity in 2019-nCoV-infected patients in Shenzhen,China.All 12 cases of the 2019-nCoV-infected patients developed pneumonia and half of them developed acute respiratory distress syndrome (ARDS).The most common laboratory abnormalities were hypoalbuminemia,lymphopenia,decreased percentage of lymphocytes (LYM) and neutrophils (NEU),elevated C-reactive protein (CRP) and lactate dehydrogenase (LDH),and decreased CD8 count.The viral load of 2019-nCoV detected from patient respiratory tracts was positively linked to lung disease severity.ALB,LYM,LYM (%),LDH,NEU (%),and CRP were highly correlated to the acute lung injury.Age,viral load,lung injury score,and blood biochemistry indexes,albumin (ALB),CRP,LDH,LYM (%),LYM,and NEU (%),may be predictors of disease severity.Moreover,the Angiotensin Ⅱlevel in the plasma sample from 2019-nCoV infected patients was markedly elevated and linearly associated to viral load and lung injury.Our results suggest a number of potential diagnosis biomarkers and angiotensin receptor blocker (ARB) drugs for potential repurposing treatment of 2019-nCoV infection.Yingxia Liu Yang Yang Cong Zhang Fengming Huang Fuxiang Wang Jing Yuan Zhaoqin Wang Jinxiu Li Jianming Li Cheng Feng Zheng Zhang Lifei Wang Ling Peng Li Chen Yuhao Qin Dandan Zhao Shuguang Tan Lu Yin Jun Xu Congzhao Zhou Chengyu Jiang Lei Liu 2020Science China(Life Sciences)2020,63,3:157
2Future Physics Programme of BESⅢ显示文摘There has recently been a dramatic renewal of interest in hadron spectroscopy and charm physics. This renaissance has been driven in part by the discovery of a plethora of charmonium-like XYZ states at BESⅢ and B factories, and the observation of an intriguing proton-antiproton threshold enhancement and the possibly related X(1835) meson state at BESⅢ, as well as the threshold measurements of charm mesons and charm baryons. We present a detailed survey of the important topics in tau-charm physics and hadron physics that can be further explored at BESⅢ during the remaining operation period of BEPCⅡ. This survey will help in the optimization of the data-taking plan over the coming years, and provides physics motivation for the possible upgrade of BEPCⅡ to higher luminosity.M.Ablikim M.N.Achasov P.Adlarson S.Ahmed M.Albrecht M.Alekseev A.Amoroso F.F.An Q.An Y.Bai O.Bakina R.Baldini Ferroli Y.Ban K.Begzsuren J.V.Bennett N.Berger M.Bertani D.Bettoni F.Bianchi J Biernat J.Bloms I.Boyko R.A.Briere L.Calibbi H.Cai X.Cai A.Calcaterra G.F.Cao N.Cao S.A.Cetin J.Chai J.F.Chang W.L.Chang J.Charles G.Chelkov Chen G.Chen H.S.Chen J.C.Chen M.L.Chen S.J.Chen Y.B.Chen H.Y.Cheng W.Cheng G.Cibinetto F.Cossio X.F.Cui H.L.Dai J.P.Dai X.C.Dai A.Dbeyssi D.Dedovich Z.Y.Deng A.Denig Denysenko M.Destefanis S.Descotes-Genon F.De Mori Y.Ding C.Dong J.Dong L.Y.Dong M.Y.Dong Z.L.Dou S.X.Du S.I.Eidelman J.Z.Fan J.Fang S.S.Fang Y.Fang R.Farinelli L.Fava F.Feldbauer G.Felici C.Q.Feng M.Fritsch C.D.Fu Y.Fu Q.Gao X.L.Gao Y.Gao Y.Gao Y.G.Gao Z.Gao B.Garillon I.Garzia E.M.Gersabeck A.Gilman K.Goetzen L.Gong W.X.Gong W.Gradl M.Greco L.M.Gu M.H.Gu Y.T.Gu A.Q.Guo F.K.Guo L.B.Guo R.P.Guo Y.P.Guo A.Guskov S.Han X.Q.Hao F.A.Harris K.L.He F.H.Heinsius T.Held Y.K.Heng Y.R.Hou Z.L.Hou H.M.Hu J.F.Hu T.Hu Y.Hu G.S.Huang J.S.Huang X.T.Huang X.Z.Huang Z.L.Huang N.Huesken T.Hussain W.Ikegami Andersson W.Imoehl M.Irshad Q.Ji Q.P.Ji X.B.Ji X.L.Ji H.L.Jiang X.S.Jiang X.Y.Jiang J.B.Jiao Z.Jiao D.P.Jin S.Jin Y.Jin T.Johansson N.Kalantar-Nayestanaki X.S.Kang R.Kappert M.Kavatsyuk B.C.Ke I.K.Keshk T.Khan A.Khoukaz P.Kiese R.Kiuchi R.Kliemt L.Koch O.B.Kolcu B.Kopf M.Kuemmel M.Kuessner A.Kupsc M.Kurth M.G.Kurth W.Kuhn J.S.Lange P.Larin L.Lavezzi H.Leithoff T.Lenz C.Li Cheng Li D.M.Li F.Li F.Y.Li G.Li H.B.Li H.J.Li J.C.Li J.W.Li Ke Li L.K.Li Lei Li P.L.Li P.R.Li Q.Y.Li W.D.Li W.G.Li X.H.Li X.L.Li X.N.Li X.Q.Li Z.B.Li H.Liang H.Liang Y.F.Liang Y.T.Liang G.R.Liao L.Z.Liao J.Libby C.X.Lin D.X.Lin Y.J.Lin B.Liu B.J.Liu C.X.Liu D.Liu D.Y.Liu F.H.Liu Fang Liu Feng Liu H.B.Liu H.M.Liu Huanhuan Liu Huihui Liu J.B.Liu J.Y.Liu K.Y.Liu Ke Liu Q.Liu S.B.Liu T.Liu X.Liu X.Y.Liu Y.B.Liu Z.A.Liu Zhiqing Liu Y.F.Long X.C.Lou H.J.Lu J.D.Lu J.G.Lu Y.Lu Y.P.Lu C.L.Luo M.X.Luo P.W.Luo T.Luo X.L.Luo S.Lusso X.R.Lyu F.C.Ma H.L.Ma L.L.Ma M.M.Ma Q.M.Ma X.N.Ma X.X.Ma X.Y.Ma Y.M.Ma F.E.Maas M.Maggiora S.Maldaner S.Malde Q.A.Malik A.Mangoni Y.J.Mao Z.P.Mao S.Marcello Z.X.Meng J.G.Messchendorp G.Mezzadri J.Min T.J.Min R.E.Mitchell X.H.Mo Y.J.Mo C.Morales Morales N.Yu.Muchnoi H.Muramatsu A.Mustafa S.Nakhoul Y.Nefedov F.Nerling I.B.Nikolaev Z.Ning S.Nisar S.L.Niu S.L.Olsen Q.Ouyang S.Pacetti Y.Pan M.Papenbrock P.Patteri M.Pelizaeus H.P.Peng K.Peters A.A.Petrov J.Pettersson J.L.Ping R.G.Ping A.Pitka R.Poling V.Prasad M.Qi T.Y.Qi S.Qian C.F.Qiao N.Qin X.P.Qin X.S.Qin Z.H.Qin J.F.Qiu S.Q.Qu K.H.Rashid C.F.Redmer M.Richter M.Ripka A.Rivetti V.Rodin M.Rolo G.Rong J.L.Rosner Ch.Rosner M.Rump A.Sarantsev M.Savrie K.Schoenning W.Shan X.Y.Shan M.Shao C.P.Shen P.X.Shen X.Y.Shen H.Y.Sheng X.Shi X.D Shi J.J.Song Q.Q.Song X.Y.Song S.Sosio C.Sowa S.Spataro F.F.Sui G.X.Sun J.F.Sun L.Sun S.S.Sun X.H.Sun Y.J.Sun Y.K Sun Y.Z.Sun Z.J.Sun Z.T.Sun Y.T Tan C.J.Tang G.Y.Tang X.Tang V.Thoren B.Tsednee I.Uman B.Wang B.L.Wang C.W.Wang D.Y.Wang H.H.Wang K.Wang L.L.Wang L.S.Wang M.Wang M.Z.Wang Wang Meng P.L.Wang R.M.Wang W.P.Wang X.Wang X.F.Wang X.L.Wang Y.Wang Y.F.Wang Z.Wang Z.G.Wang Z.Y.Wang Zongyuan Wang T.Weber D.H.Wei P.Weidenkaff H.W.Wen S.P.Wen U.Wiedner G.Wilkinson M.Wolke L.H.Wu L.J.Wu Z.Wu L.Xia Y.Xia S.Y.Xiao Y.J.Xiao Z.J.Xiao Y.G.Xie Y.H.Xie T.Y.Xing X.A.Xiong Q.L.Xiu G.F.Xu L.Xu Q.J.Xu W.Xu X.P.Xu F.Yan L.Yan W.B.Yan W.C.Yan Y.H.Yan H.J.Yang H.X.Yang L.Yang R.X.Yang S.L.Yang Y.H.Yang Y.X.Yang Yifan Yang Z.Q.Yang M.Ye M.H.Ye J.H.Yin Z.Y.You B.X.Yu C.X.Yu J.S.Yu C.Z.Yuan X.Q.Yuan Y.Yuan A.Yuncu A.A.Zafar Y.Zeng B.X.Zhang B.Y.Zhang C.C.Zhang D.H.Zhang H.H.Zhang H.Y.Zhang J.Zhang J.L.Zhang J.Q.Zhang J.W.Zhang J.Y.Zhang J.Z.Zhang K.Zhang L.Zhang S.F.Zhang T.J.Zhang X.Y.Zhang Y.Zhang Y.H.Zhang Y.T.Zhang Yang Zhang Yao Zhang Yi Zhang Yu Zhang Z.H.Zhang Z.P.Zhang Z.Q.Zhang Z.Y.Zhang G.Zhao J.W.Zhao J.Y.Zhao J.Z.Zhao Lei Zhao Ling Zhao M.G.Zhao Q.Zhao S.J.Zhao T.C.Zhao Y.B.Zhao Z.G.Zhao A.Zhemchugov B.Zheng J.P.Zheng Y.Zheng Y.H.Zheng B.Zhong L.Zhou L.P.Zhou Q.Zhou X.Zhou X.K.Zhou Xingyu Zhou Xiaoyu Zhou Xu Zhou A.N.Zhu J.Zhu J.Zhu K.Zhu K.J.Zhu S.H.Zhu W.J.Zhu X.L.Zhu Y.C.Zhu Y.S.Zhu Z.A.Zhu J.Zhuang B.S.Zou J.H.Zou 2020Chinese Physics C2020,44,4:517
3Effect of phosphorylation of MAPK and Stat3 and expression of c-fos and c-jun proteins on hepatocarcinogenesis and their clinical significance显示文摘AIM To study the effect of phosphorylation ofMAPK and Stat3 and the expression of c-fos andc-jun proteins on hepatocellular carcinogenesisand their clinical significance.METHODS SP immunohistochemistry was usedto detect the expression of p42/44MAPK, p-Stat3,c-fos and c-jun proteins in 55 hepatocellularcarcinomas (HCC) and their surrounding livertissues.RESULTS The positive rates and expressionlevels of p42/44MAPK, p-Stat3, c-fos and c-junproteins in HCCs were significantly higher thanthose in pericarcinomatous liver tissues (PCLT).A positive correlation was observed between theexpression of p42/44MAPK and c-fos proteins, andbetween p-Stat3 and c-jun, but there was nosignificant correlation between p42/44MAPK and p-Stat3 in HCCs and their surrounding livertissues.CONCLUSION The abnormalities of Ras/Rat/MAPK and JAKs/ Stat3 cascade reaction maycontribute to malignant transformation ofhepatocytes. Hepatocytes which are positive forp42/ 44MAPK, c-fos or c-jun proteins may bepotential malignant pre-cancerous cells.Activation of MAPK and Stat3 proteins may be anearly event in hepatocellular carcinogenesis.De Yun Feng Hui Zheng Yi Tan Rui Xue Cheng Department of Pathology, Hunan Medical University, Changsha 410078, Hunan Province, China New England Biolab, MA, USA 2001World Journal of Gastroenterology2001,7,1:75
4Prognostic factors and long-term outcomes of hilar cholangiocarcinoma:A single-institution experience in China显示文摘AIM: To evaluate the prognostic factors of hilar cholangiocarcinoma in a large series of patients in a single institution.METHODS: Eight hundred and fourteen patients with a diagnosis of hilar cholangiocarcinoma that were evaluated and treated between 1990 and 2014, of which 381 patients underwent curative surgery, were included in this study. Potential factors associated with overall survival(OS) and disease-free survival(DFS) were evaluated by univariate and multivariate analyses.RESULTS: Curative surgery provided the best long-term survival with a median OS of 26.3 mo. The median DFS was 18.1 mo. Multivariate analysis showed that patients with tumor size > 3 cm [hazard ratio(HR) = 1.482, 95%CI: 1.127-1.949; P = 0.005], positive nodal disease(HR = 1.701, 95%CI: 1.346-2.149; P < 0.001), poor differentiation(HR = 2.535, 95%CI: 1.839-3.493; P < 0.001), vascular invasion(HR = 1.542, 95%CI: 1.082-2.197; P = 0.017), and positive margins(HR = 1.798, 95%CI: 1.314-2.461; P < 0.001) had poor OS outcome. The independent factors for DFS were positive nodal disease(HR = 3.383, 95%CI: 2.633-4.348; P < 0.001), poor differentiation(HR = 2.774, 95%CI: 2.012-3.823; P < 0.001), vascular invasion(HR = 2.136, 95%CI: 1.658-3.236; P < 0.001), and positive margins(HR = 1.835, 95%CI: 1.256-2.679; P < 0.001). Multiple logistic regression analysis showed that caudate lobectomy [odds ratio(OR) = 9.771, 95%CI: 4.672-20.433; P < 0.001], tumor diameter(OR = 3.772, 95%CI: 1.914-7.434; P < 0.001), surgical procedures(OR = 10.236, 95%CI: 4.738-22.116; P < 0.001), American Joint Committee On Cancer T stage(OR = 2.010, 95%CI: 1.043-3.870; P = 0.037), and vascular invasion(OR = 2.278, 95%CI: 0.997-5.207; P = 0.051) were independently associated with tumorfree margin, and surgical procedures could indirectly affect survival outcome by influencing the tumor resection margin. CONCLUSION: Tumor margin, tumor differentiation, vascular invasion, and lymph node status were independent factors for OS and DFS. Surgical procedures can indirectly affect survival outcome by influencing the tumor resection margin.Hai-Jie Hu Hui Mao Anuj Shrestha Yong-Qiong Tan Wen-Jie Ma Qin Yang Jun-Ke Wang Nan-Sheng Cheng Fu-Yu Li 2016World Journal of Gastroenterology2016,22,8:40
5Rho/ROCK pathway and neural regeneration: a potential therapeutic target for central nervous system and optic nerve damage显示文摘· Rho-associated kinase (ROCK) is a serine/threonine kinase and one of the major downstream effectors of the small GTPase RhoA. The Rho/ROCK pathway is closely related to the pathogenesis of several central nervous system (CNS) disorders, and involved in many aspects of neuronal functions including neurite outgrowth and retraction. In the adult CNS, the damaged neuron regeneration is very difficult due to the presence of myelin-associated axon growth inhibitors such as Nogo, myelin-associated glycoprotein (MAG) and oligodendrocyte-myelin glycoprotein (Omgp), etc. The effects of these axon growth inhibitors are reversed by blocking the Rho/ROCK pathway in vitro, and the inhibition of Rho/ROCK pathway can promote axon regeneration and functional recovery in the injured CNS in vivo. In addition, the therapeutic effects of the Rho/ROCK inhibitors have also been demonstrated in some animal models and the Rho/ROCK pathway becomes an attractive target for the development of drugs for treating CNS disorders. In this review, we summarized on the effect of the Rho and the downstream factor ROCK in neural regeneration, and the potential therapeutic effect of Rho/ROCK inhibitors in the survival and axonal regeneration of retinal ganglion cells was also discussed. ·Hai-Bo Tan Yi-Sheng Zhong Yu Cheng and Xi Shen 2011International Journal of Ophthalmology(English edition)2011,4,6:31

8Characteristics of one-year observation of VOCs,NOx, and O_3 at an urban site in Wuhan, China显示文摘A continuous online observation of ozone and its precursors(NOx, VOCs) was carried out in central urban Wuhan from September 2016 to August 2017. The concentration levels of ozone,NOx, VOCs and their variations in urban Wuhan were analyzed, as well as effects of VOCs on ozone photochemical generation and the main controlling factors for ozone production. During the observation period, the average concentrations of ozone and NOx in Wuhan was 22.63 and30.14 ppbv, respectively, and the average concentration of VOCs was 32.61 ppbv(42.3% alkanes,13.0% alkenes, 10.0% aromatics, 7.3% acetylene, 9.9% OVOCs, and 10.5% halohydrocarbons).Ozone concentration was higher in spring and summer as compared with autumn and winter,wheras VOCs and NOx concentratios were lower in spring and summer but higher in autumn and winter. Aromatics and alkenes, two of VOCs species, showed the highest contributions to ozone formation potential in Wuhan(35.7% alkenes, 35.4 aromatics, 17.5% alkanes, 8.6% OVOCs,1.6% halogenated hydrocarbons, and 1.4% acetylene). Among all VOCs species, those with the highest contribution were ethylene, m-xylene, toluene, propylene and o-xylene. The contribution of these five compounds to the total ozone formation potential concentration was 43.90%.Ozone-controlling factors in Wuhan changed within one day; during the early morning hours(6:00–9:00), VOCs/NOx was low, and ozone generation followed a VOCs-limited regime.However, during the peak time of ozone concentration(12:00–16:00), the ratio of VOCs/NOx was relatively high, suggesting that ozone generation followed a NOx-limited regime.Yichang Yang Xingang Liu Jun Zheng Qinwen Tan Miao Feng Yu Qu Junling An Nianliang Cheng 2019Journal of Environmental Sciences2019,31,5:26
9The Aging Feature of Al-L-Cu-Mg-Zr Alloy Containing Sc显示文摘The aging behaviors of Al 1.42%Li 2.41%Cu 0.93%Mg 0.073%Zr 0.17%Sc(mass fraction, the same below) alloy at room temperature, 160 ℃ , and 160 ℃ after 8% pre deformation were studied respectively by hardness measurement. The microstructure of the alloy in various aging conditions was observed by TEM. The results show that the main precipitations of the alloy in quenching condition are the particles containing Sc and Zr which have certain coherent relation with the matrix. Addition of Sc in Al Li Cu Mg Zr alloy will be favorable to promoting precipitation. The particles can serve as preferred nucleation sites for δ′ phases which accelerate the aging hardening rate at initial aging. The main hardening phases of the alloy aged at 160 ℃ are δ′ and δ′/β′ composite precipitates. The size of the composite precipitates is very small (nanometer size). The composite precipitates will preclude efficiently the formation concentrative slip location and will improve the mechanical properties of the alloy. S′ phase will occur in the alloy aged at 160 ℃ after 8% pre deformation. It is found that 8% pre deformation has no obvious influence on the precipitation of the composite phase.TAN Cheng yu,ZHENG Zi qiao,XIA Chang qing,LIANG Ying (Department of Materials Science and Engineering, Central South University of Technology, Changsha 410083, China) 2000Journal of Central South University2000,12,2:22
10Osteoimmunomodulatory effects of biomaterial modification strategies on macrophage polarization and bone regeneration显示文摘Biomaterials as bone substitutes are always considered as foreign bodies that can trigger host immune responses.Traditional designing principles have been always aimed at minimizing the immune reactions by fabricating inert biomaterials.However,clinical evidence revealed that those methods still have limitations and many of which were only feasible in the laboratory.Currently,osteoimmunology,the very pioneering concept is drawing more and more attention-it does not simply regard the immune response as an obstacle during bone healing but emphasizes the intimate relationship of the immune and skeletal system,which includes diverse cells,cytokines,and signaling pathways.Properties of biomaterials like topography,wettability,surface charge,the release of cytokines,mediators,ions and other bioactive molecules can impose effects on immune responses to interfere with the skeletal system.Based on the bone formation mechanisms,the designing methods of the biomaterials change from immune evasive to immune reprogramming.Here,we discuss the osteoimmunomodulatory effects of the new modification strategies—adjusting properties of bone biomaterials to induce a favorable osteoimmune environment.Such strategies showed potential to benefit the development of bone materials and lay a solid foundation for the future clinical application.Yajuan Xie Cheng Hu Yi Feng Danfeng Li Tingting Ai Yulei Huang Xiaodan Chen Lijia Huang Jiali Tan 2020Regenerative Biomaterials2020,7,3:22
11Immunoregulatory effects of Tripterygium wilfordii Hook Fand its extracts in clinical practice显示文摘Tripterygium wilfordii Hook F (TwHF) and its extracts have long been used for the treatment of rheumatoid arthritis, autoimmune diseases, and kidney disease due to their anti-inflammatory, immunoregulatory, and other pharmacological effects. However, the clinical immunoregulatory effects of TwHF and its extracts remain unclear, so we reviewed their effects for use in clinical practice. This review provides a comprehensive summary of the recent literature on the immunoregulatory effects of TwHF and its extracts in clinical studies. TwHF and its extracts affect the proliferation and activation of T and B cells;ratio of T cell subsets;inflammatory response of monocytes, macrophages, and immunoglobulins;and secretion of many cytokines. Together, these effects dictate immune function in a variety of diseases. TwHF and its extracts can be used alone or in combination with existing therapies against many immune disorders through immunomodulation.Dan Luo Zhengyun Zuo Hongyan Zhao Yong Tan Cheng Xiao 2019Frontiers of Medicine2019,13,5:19
12Antigenic variation of the human influenza A(H3N2) virus during the 2014–2015 winter season显示文摘The human influenza A(H3N2) virus dominated the 2014–2015 winter season in many countries and caused massive morbidity and mortality because of its antigenic variation. So far, very little is known about the antigenic patterns of the recent H3N2 virus. By systematically mapping the antigenic relationships of H3N2 strains isolat ed since 2010, we discov ered that two groups with obvious antigenic divergence, named SW13(A/Switzerland/9715293/2013-like strains) and HK14(A/Hong Kong/5738/2014-like strains), co-circulated during the 2014–2015 winter season. HK14 group co-circulated with SW13 in Europe and the United States during this season, while there were few strains of HK14 in China's Mainland, where SW13 has dominated since 2012. Furthermore, we found that substitutions near the receptor-binding site on hemagglutinin played an important role in the antigenic variation of both the groups. These findings provide a comprehensive understanding of the recent antigenic evolution of H3N2 virus and will aid in the selection of vaccine strains.HUA Sha LI XiYan LIU Mi CHENG YanHui PENG YouSong HUANG WeiJuan TAN MinJu WEI HeJiang GUO JunFeng WANG DaYan WU AiPing SHU YueLong JIANG TaiJiao 2015Science China(Life Sciences)2015,58,9:17
13Facile metagrating holograms with broadband and extreme angle tolerance显示文摘The emerging meta-holograms rely on arrays of intractable meta-atoms with various geometries and sizes for customized phase profiles that can precisely modulate the phase of a wavefront at an optimal incident angle for given wavelengths.The stringent and band-limited angle tolerance remains a fundamental obstacle for their practical application,in addition to high fabrication precision demands.Utilizing a different design principle,we determined that facile metagrating holograms based on extraordinary optical diffraction can allow the molding of arbitrary wavefronts with extreme angle tolerances(near-grazing incidence)in the visible–near-infrared regime.By modulating the displacements between uniformly sized meta-atoms rather than the geometrical parameters,the metagratings produce a robust detour phase profile that is irrespective of the wavelength or incident angle.The demonstration of high-fidelity meta-holograms and in-site polarization multiplexing significantly simplifies the metasurface design and lowers the fabrication demand,thereby opening new routes for flat optics with high performances and improved practicality.Zi-Lan Deng Junhong Deng Xin Zhuang Shuai Wang Tan Shi Guo Ping Wang Yao Wang Jian Xu Yaoyu Cao Xiaolei Wang Xing Cheng Guixin Li Xiangping Li 2018Light(Science & Applications)2018,7,1:17

15Changes of the proportion and mortality of pulmonary thromboembolism in hospitalized patients from 1974 to 2005显示文摘Background Pulmonary thromboembolism (PTE) has become a common disease that severely endangers people’s health. This study analysed the changes in proportion and mortality of PTE in hospitalized patients to provide data for prevention and management of the disease. Methods The data of 763 hospitalized patients with PTE from 1974 to 2005 in Fuwai Hospital were analysed. Results During the 1970s, 0.27% of patients in a cardiovascular hospital had PTE (< 5 cases per year); while so far this century the proportion is 0.94% (48 to 113 per year). The mortality of hospitalized PTE patients fell from 20.00% in the 1970s to 4.10% this century. Prior to 1990, the mortality of hospitalized PTE patients was 12.50%, and in the years after 1990 only 3.40%. The difference was statistically significant (P<0.005). People with this disease were mostly between the ages of 30 and 69 years. Men were most susceptible between the ages of 30 and 69 years, while women between the ages of 40 and 69 years. Men contracted PTE 10 years earlier than women. The mortality of male PTE patients was 4.70%, not significantly different from female patients, 5.06% (0.500.1). More people contracted the disease in winter than in other seasons (P<0.05).

16Stability of QTL Across Environments and QTL-by-Environment Interactions for Plant and Ear Height in Maize显示文摘Better understanding of genotype-by-environment interaction(GEI)is expected to provide a solid foundation for genetic improvement of crop productivity especially under drought-prone environments.To elucidate the genetic basis of the plant and ear height,2 F2:3 populations were derived from the crosses of Qi 319 × Huangzaosi(Q/H)and Ye 478 × Huangzaosi(Y/H)with 230 and 235 families,respectively,and their parents were evaluated under 3 diverse environments in Henan,Beijing,and Xinjiang,China during the year of 2007 and 2008,and all the lines were also evaluated under water stress environment.The mapping results showed that a total of 21 and 12 QTLs were identified for plant height in the Q/H and Y/H population,respectively,and 24 and 13 QTLs for ear height,respectively.About 56 and 73% of the QTLs for 2 traits did not present significant QTL-by-environment interaction(QEI)in the normal joint analyses for Q/H and Y/H population,respectively,and about 73% of the QTLs detected did not show significant QEI according to joint analyses for stress condition in Q/H.Most of the detected major QTLs exhibited high stability across different environments.Besides,several major QTLs were detected with large and consistent effect under normal condition(Chr.6 and 7 in Q/H;Chr.1,3 and 9 in Y/H),or across 2 water regimes(Chr.1,8 and 10 for in Q/H).There were several constitutive QTLs(3 for Q/H and 1 for Y/H)with no or minor QTL-by-environment for the 2 populations.Finally,we found several genomic regions(Chr.1,10,etc.)to be co-located across the populations,which could provide useful reference for genetic improvement of these traits in maize breeding programs.Comparative genomic analysis revealed that 3 genes/genetic segments associated with plant height in rice were orthologous to these 3 identified genomic regions carrying the major QTLs for plant and ear height on Chr.1,6,and 8,respectively.ZHANG Yan LI Yong-xiang WANG Wang LIU Zhi-zhai LIU Cheng PENG Bo TAN Wei-wei WANG Di SHI Yun-su SUN Bao-cheng SONG Yan-chun WANG Tian-yu LI Yu 2010Agricultural Sciences in China2010,9,10:16

19Radiomics approach for preoperative identification of stages Ⅰ-Ⅱand Ⅲ-Ⅳ of esophageal cancer显示文摘Objective: To predict preoperative staging using a radiomics approach based on computed tomography(CT)images of patients with esophageal squamous cell carcinoma(ESCC).Methods: This retrospective study included 154 patients(primary cohort: n=114; validation cohort: n=40) with pathologically confirmed ESCC. All patients underwent a preoperative CT scan from the neck to abdomen. High throughput and quantitative radiomics features were extracted from the CT images for each patient. A radiomics signature was constructed using the least absolute shrinkage and selection operator(Lasso). Associations between radiomics signature, tumor volume and ESCC staging were explored. Diagnostic performance of radiomics approach and tumor volume for discriminating between stages Ⅰ-Ⅱ and Ⅲ-Ⅳ was evaluated and compared using the receiver operating characteristics(ROC) curves and net reclassification improvement(NRI).Results: A total of 9,790 radiomics features were extracted. Ten features were selected to build a radiomics signature after feature dimension reduction. The radiomics signature was significantly associated with ESCC staging(P<0.001), and yielded a better performance for discrimination of early and advanced stage ESCC compared to tumor volume in both the primary [area under the receiver operating characteristic curve(AUC): 0.795 vs. 0.694,P=0.003; NRI=0.424)] and validation cohorts(AUC: 0.762 vs. 0.624, P=0.035; NRI=0.834).Conclusions: The quantitative approach has the potential to identify stage Ⅰ-Ⅱ and Ⅲ-Ⅳ ESCC before treatment.Lei WU Cong Wang Xianzheng Tan Zixuan Cheng Ke Zhao Lifen Yan Yanli Liang Zaiyi Liu Changhong Liang 2018Chinese Journal of Cancer Research2018,30,4:14
