1CD30 expression in extranodal natural killer/T-cell lymphoma,nasal type among 622 cases of mature T-cell and natural killer-cell lymphoma at a single institution in South China显示文摘Background:Mature T-cell and natural killer(NK)-cell lymphomas compose a heterogeneous group of non-Hodgkin lymphomas,and extranodal NK/T-cell lymphoma,nasal type(ENKTL) is an aggressive subtype with sporadic CD30 expression.However,the significance of CD30 expression in ENKTL is controversial.We aimed to classify a large cohort of patients with mature T-cell and NK-cell lymphomas according to the 2016 World Health Organization(WHO) classification guidelines and to study the association between CD30 expression and prognosis of patients with ENKTL.Methods:We selected consecutive patients with mature T-cell and NK-cell lymphomas who attended our institution between September 1,2009 and August 31,2013.We classified the lymphomas according to the 2016 revision of the WHO classification of lymphoid neoplasms,analyzed the associations between CD30 expression and clinicopathologic features of ENKTL patients,and evaluated the prognostic implications of CD30 expression.Results:We identified 622 consecutive patients with mature T-cell and NK-cell lymphomas,including 317(51.0%)patients with ENKTL.In addition,CD30 expression was detected in 43(47.3%) of a subset of 91 patients with ENKTL.No clinicopathologic features were associated with CD30 expression,and CD30 positivity showed no prognostic significance in patients with ENKTL.Conclusions:ENKTL is the most common type of mature T-cell and NK-cell lymphoma diagnosed at our institution.CD30 is frequently expressed in ENKTL and represents a therapeutic target;however,it may not be a prognostic marker.Yanfen Feng Huilan Rao Yiyan Lei Yuhua Huang Fang Wang Yu Zhang Shaoyan Xi Qiuliang Wu Jianyong Shao 2017Chinese Journal of Cancer2017,36,6:10
2A statistical investigation of pre-earthquake ionospheric TEC anomalies显示文摘Previous researches show that the total electron content (TEC) in the ionospheric exhibits anomalous disturbances a few days or hours prior to earthquakes. The paper used TEC data from Internet GPS Service (IGS), and examined 50 earthquakes of magnitude Ms≥7.0 during 2007-2009 worldwide. The result shows significant anomalous increases and decreases about 7 days prior to 94% of the earthquakes.Zhu Fuying Wu Yun Zhou Yiyan Lin Jian 2011Geodesy and Geodynamics2011,2,1:5
3Type-Ⅱ Core/Shell Nanowire Heterostructures and Their Photovoltaic Applications显示文摘Nanowire-based photovoltaic devices have the advantages over planar devices in light absorption and charge transport and collection.Recently,a new strategy relying on type-Ⅱ band alignment has been proposed to facilitate efficient charge separation in core/shell nanowire solar cells.This paper reviews the type-Ⅱ heterojunction solar cells based on core/shell nanowire arrays,and specifically focuses on the progress of theoretical design and fabrication of type-Ⅱ Zn O/Zn Se core/shell nanowire-based solar cells.A strong photoresponse associated with the type-Ⅱ interfacial transition exhibits a threshold of 1.6 e V,which demonstrates the feasibility and great potential for exploring all-inorganic versions of type-Ⅱ heterojunction solar cells using wide bandgap semiconductors.Future prospects in this area are also outlooked.Yiyan Cao Zhiming Wu Jianchao Ni Waseem.A.Bhutto Jing Li Shuping Li Kai Huang Junyong Kang 2012Nano-Micro Letters2012,4,3:3
4Temporal and spatial characteristics of VTEC anomalies before Wenchuan Ms8.0 earthquake显示文摘GPS and the COD VTEC data were studied in search of ionospheric VTEC changes in space and time that might be associated with the Wenchuan Ms8.0 earthquake on 12 May,2008.The result shows several significant anomalous decreases at 12:00 UT-16:00 UT on April 29 and an anomalously increase at 14:00 UT-18:00 UT on May 9.The anomalies had two humps,that were located on both sides of the geomagnetic equator and had a tendency of drifting towards the equator.Since the observed anomalies cannot be attributed to any other causes and since they occurred close to the time of the earthquake,we consider them to be possibly premonitory to the earthquake.Fuying Zhu Yun Wu Jian Lin Yiyan Zhou 2010Geodesy and Geodynamics2010,1,1:2
