9Clinical features and outcomes of diffuse large B-cell lymphoma based on nodal or extranodal primary sites of origin:Analysis of 1,085 WHO classified cases in a single institution in China显示文摘Objective: To explore the clinicobiologic features and outcomes of diffuse large B-cell lymphoma(DLBCL)patients in China according to the primary site.Methods: A total of 1,085 patients diagnosed with DLBCL in National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College during a 6-year period were enrolled. Their clinical characteristics and outcomes were analyzed according to the primary site.Results: In the 1,085 patients, 679(62.6%) cases were nodal DLBCL(N-DLBCL) and 406 cases(37.4%) were extranodal DLBCL(EN-DLBCL). The most common sites of N-DLBCL were lymphonodus(64.8%), Waldeyer's ring(19.7%), mediastinum(12.8%) and spleen(2.7%), while in EN-DLBCL, stomach(22.4%), intestine(16.0%),nose and sinuses(8.9%), testis(8.4%), skin(7.9%), thyroid(6.9%), central nervous system(CNS)(6.4%), breast(5.7%), bone(3.4%), and salivary gland(2.7%) were most common. N-DLBCL patients tend to present B symptoms, bulky disease, and elevated LDH more often, while age >60 years, extranodal sites >1, Ann Arbor stage I or II, bone marrow involvement, and Ki-67 index >90% were usually seen in EN-DLBCL. The 5-year overall survival(OS) rate and progression-free survival(PFS) rate for all patients were 62.5% and 54.2%. The 5-year OS rate for patients with N-DLBCL and EN-DLBCL were 65.5% and 56.9%(P=0.008), and the 5-year PFS were57.0% and 49.0%(P=0.020). Waldeyer's ring originated DLBCL possessed the highest 5-year OS rate(83.6%) and PFS rate(76.9%) in N-DLBCL. The top five EN-DLBCL subtypes with favorable prognosis were stomach,breast, nose and sinuses, lung, salivary gland, with 5-year OS rate: 70.3%, 69.6%, 69.4%, 66.7% and 63.6%,respectively. While CNS, testis, oral cavity and kidney originated EN-DLBCL faced miserable prognosis, with 5-year OS rate of 26.9%, 38.2%, and 42.9%.Conclusions: In our study, primary sites were associated with clinical characteristics and outcomes. Compared with EN-DLBCL, N-DLBCL had better prognosis.Yuankai Shi Ying Han Jianliang Yang Peng Liu Xiaohui He Changgong Zhang Shengyu Zhou Liqiang Zhou Yan Qin Yongwen Song Yueping Liu Shulian Wang Jing Jin Lin Gui Yan Sun 2019Chinese Journal of Cancer Research2019,31,1:19
10SHRIMP zircon U-Pb ages and tectonic implications for Indosinian granitoids of southern Zhuguangshan granitic composite, South China显示文摘The large southern Zhuguangshan granitic batholith composite consists of granites with ages varying from the Caledonian through Indosinian to Yanshanian. Based on K-Ar dating data, the ages of the major parts of this composite were previously regarded as Yanshanian. In this study, the SHRIMP zircon U-Pb dating method has been adopted for six plutons, Ledong, Longhuashan, Dawozi, Zhaidi, Baiyun and Jiangnan, in the southern Zhuguangshan composite, in which the four plutons other than Baiyun and Jiangnan were previously regarded as Yanshanian granites. Magmatic zircons from these six plutons, dated by this study, have yielded ages of 239±5 Ma (MSWD = 2.5), 239±5 Ma (MSWD = 2.5), 239±2 Ma (MSWD = 1.7), 239±4 Ma (MSWD = 3.2), 231±2 Ma (MSWD = 0.81) and 231±3 Ma (MSWD = 1.8), respectively. The results indicate that these plutons were formed by early Indosinian magmatism. Geochemical characteristics suggest that these granites were formed in an extensional tectonic environment. Therefore, the Indosinian period granites in the southern Zhuguangshan composite were formed by partial melting of the Paleo-Mesoproterozoic crustal components during the collapse of thickened lithosphere after the collision between the South China and Indosinian plates.DENG Ping REN JiShun LING HongFei SHEN WeiZhou SUN LiQiang ZHU Ba TAN ZhengZhong 2012Chinese Science Bulletin2012,57,13:19
11Encapsulating segment-like antimony nanorod in hollow carbon tube as long-lifespan,high-rate anodes for rechargeable K-ion batteries显示文摘K-ion battery (KIB) is a new-type energy storage device that possesses potential advantages of low-cost and abundant resource of potassium.To develop advanced electrode materials for accommodating the large size and high activity of potassium ion is of great interests.Herein,a segment-like antimony (Sb) nanorod encapsulated in hollow carbon tube electrode material (Sb@HCT) was prepared.Beneficial from the virtue of abundant nitrogen doping in carbon tube,one-dimensional and hollow structure advantages,Sb@HCT exhibits excellent potassium storage properties:in the case of potassium bis(fluorosulfonyl)imide (KFSI) electrolyte,Sb@HCT displays a reversible capacity of up to 453.4 mAh·g^-1 at a current density of 0.5 A·g^-1 and good rate performance (a capacity of 211.5 mAh·g^-1 could be achieved at an ultrahigh rate of 5 A·g^-1).Additionally,Sb@HCT demonstrates excellent long-cycle stability at a current density of 2 A·g^-1 over 120 cycles.Meanwhile,electrolyte optimization is an effective strategy for greatly improving electrochemical performance.Through ex-situ characterizations,we disclosed the potassiation of Sb anode is quite reversible and undergoes multistep processes,combining solid solution reaction and two-phase reaction.Wen Luo Feng Li Weiran Zhang Kang Han Jean-Jacques Gaumet Hans-Eckhardt Schaefer Liqiang Mai 2019Nano Research2019,12,5:18
12Shear Alteration, Mass Transfer and Gold Mineralization: An Example from Jiaodong Ore Deposit Concentrating Area, Shandong, China显示文摘Taking the gold ore deposit concentrating area of Jiaodong area in Shandong, China for an example, based on geological analysis, and applying Gresens’ equation, Grant’s isocon diagram and O’hara microelement calculation method, a thorough study on shear alteration, mass transfer and gold mineralization was carried out. The authors also made mathematic simulation and geochemical analysis. The work reveals temporal spatial changing regularities of temperature field and velocity field of fluids, and also reveals fluid transport chemical reaction coupling metallogenic dynamics of the Jiaojia gold ore concentrating area. During shear alteration process of the Jiaodong gold ore concentrating area, all kinds of components transferred with different amounts, fluid rock ratio was rather high and volume strain was of dilation type. Fast flow of ore forming fluid favors the occurrence of mixed fluid. Shear fractured zones are places where there was strong transportation reaction coupling mineralization. Ore bodies were located in dilation space of shear structure where there was the greatest fluid flux. After the emplacement of the rock body, a convex heat field was formed around the rock body. It is one of the main metallogenic forces. The major reason for mineralization is the mobilization, migration and enrichment of ore forming elements induced by shear compressive extensional tectonism. Inclusion gold dominant low grade ores were formed in the early ore forming stage, while high grade ores, which contained fissure gold and polymetallic veinlets, were formed in late ore forming stage.Deng Jun Zhai Yusheng Wang Jianping Faculty of Earth Sciences and Mineral Resources, China University of Geosciences, Beijing 100083, China Yang Liqiang Institute of Geophysics, Chinese Academy of Sciences, Beijing 100101, China Fang Yun Faculty of 2000Journal of Earth Science2000,19,3:18
13Real-time and reliability analysis of time-triggered CAN-bus显示文摘Real-time performance and reliability are two most important issues in applications of time-triggered controller area network (CAN) bus systems at present. A scheduling matrix of time-triggered CAN-bus system is established using average-loading algorithm. Periodic messages are guaranteed to transmit without delay by distributing independent transmission windows within the system matrix. Considering the traditional CAN-bus transmission mechanism and the time-triggered feature, an algorithm is improved to calculate the worst-case delay of event-triggered messages in time-triggered CAN-bus systems. The failure probability is calculated for event-triggered messages whose worst-case delay exceeds their deadlines. Different levels of redundant structures of CAN-bus circuits are analyzed and the maintenance management is proposed to improve the system reliability. Finally, the reliabilities of different structures are calculated and the influences of maintenance on the system reliability are analyzed.Xia Jiqiang Zhang Chuansen Bai Ronggang Xue Liqiang 2013Chinese Journal of Aeronautics2013,26,1:17
14Quasi-real-time simulation of rotating drum using discrete element method with parallel GPU computing显示文摘Real-time simulation of industrial equipment is a huge challenge nowadays. The high performance and fine-grained parallel computing provided by graphics processing units (GPUs) bring us closer to our goals. In this article, an industrial-scale rotating drum is simulated using simplified discrete element method (DEM) without consideration of the tangential components of contact force and particle rotation. A single GPU is used first to simulate a small model system with about 8000 particles in realtime, and the simulation is then scaled up to industrial scale using more than 200 GPUs in a 1D domain-decomposition parallelization mode. The overall speed is about 1/11 of the real-time. Optimization of the communication part of the parallel GPU codes can speed up the simulation further, indicating that such real-time simulations have not only methodological but also industrial implications in the near future.Ji Xu Huabiao Oi Xiaojian Fang Liqiang Lu Wei Ge Xiaowei Wang Ming xu Feiguo Chen xianfeng He Jinghai Li 2011Particuology2011,9,4:16

16Observation of mega-dune evaporation after various rain events in the hinterland of Badain Jaran Desert, China显示文摘The formation mechanisms of the mega-dunes and lakes in the hinterland of Badain Jaran Desert,China,is the focus of extensive academic research in the field of geoscience,and an often debated topic is whether atmospheric precipitation on the mega-dune can infiltrate to recharge groundwater.In the present study,the probability distribution functions and the return period analysis of extreme daily precipitation based on long-term precipitation records for the southern margin of Badain Jaran Desert and 2-year observation of hinterland precipitation were used to classify precipitation in the desert region.The data of automatic weather station and eddy covariance system in the desert hinterland were used to analyze evaporation on the mega-dune surface after various rain events.The results showed that the rain events in the desert could be divided into three categories.The first is conventional precipitation(CP),which is below 5 mm,accounting for roughly 90%of all rain events in the desert.The second and third categories are ordinary annual maximum(OAM)and extreme precipitation(EP),in which precipitation is roughly 20 mm and more than 40 mm,respectively.The atmospheric precipitation of CP and OAM evaporated from the megadune surface in 1–3 days and 3–4 weeks,respectively.Following an EP event,the mega-dune evaporation was negatively influenced by the upper dry sand layer,and a lengthy period was required for its complete removal.The accumulative evaporation and accumulative precipitation of all three types of rain events indicated that local atmospheric precipitation had no significant contribution to recharging the groundwater system in the hinterland of Badain Jaran Desert.This research will benefit comprehensive elucidation of the formation mechanism of lakes in the hinterland of Badain Jaran Desert.Ning Ma Naiang Wang Liqiang Zhao Zhenyu Zhang Chunyu Dong Shiping Shen 2014Chinese Science Bulletin2014,59,2:14
17World-class Xincheng gold deposit: An example from the giant Jiaodong gold province显示文摘The Jiaodong gold deposits are currently the most important gold resources(with Au reserves of>4000 t) in China,and the leading gold-producing country globally(with Au production of ~428 t in2013).Jiaodong is also considered as perhaps the only world-class to giant gold accumulation on the planet where relatively young gold ores(ca.130-120 Ma) were deposited in rocks that are 2 Ga older.The Xincheng world-class high-grade gold deposit,with a proven reserve of >200 t gold,is one of the largest deposits in the giant gold province of the Jiaodong Peninsula.It is located in the northwestern part of the jiaobei Uplift,and hosted by ca.132-123 Ma Xincheng quartz monzonites and monzogranites.Ore zones are structurally controlled by the NE-trending and NW-dipping Jiaojia Fault and subsidiary faults,and are mainly restricted to the footwall of the fault.The dominant disseminated- and stockworkstyle ores are associated with strong sericitization,silicification,sulfidation and K-feldspathization,and minor carbonate wallrock alteration halos.The four mineralization stages are pyrite-quartz-sericite(stage 1),quartz-pyrite(stage 2),quartz-polysulfide(stage 3) and quartz-carbonate(stage 4).Gold occurs dominantly as electrum,with lesser amounts of sulfide-hosted native gold and rare native silver and argentite,normally associated with pyrite,chalcopyrite,galena and sphalerite:the latter with proven resources of about 105 t Ag,713 t Cu,and 5100 t S.There are three types of ore-related fluid inclusions:type 1 aqueous-carbonate(H_2O-CO_2),type 2aqueous(liquid H_2O+vapor H_2O),and type 3 CO_2(liquid CO_2 and vapor CO_2) inclusions.Homogenization temperatures range from 221 to 304℃ for type 1 inclusions,with salinities of 2.4-13.3 wt.%NaCl eq.,and bulk densities of 0.858-1.022 g/cm^3.The δ^(34)S_(CDT) values of hydrothermal sulfides are 4.3-10.6‰and δ^(18)O values of hydrothermal quartz have a median value of 13.0‰.δD values of fluid inclusions in hydrothermal quartz have a median value of-75‰.Calculated δ^(18)Owater has a median value of 5.2‰.The timing of gold mineralization at the Xincheng gold deposit is younger than 123±1 Ma,and likely between 120.9 and 119.9 Ma.A minerals system genetic model for the probable epizonal orogenic Xincheng deposit suggests an initial medium temperature,CO_2-rich,and low salinity H_2O-CO_2 deeply sourced metamorphic ore fluid associated with dehydration and decarbonization of subducting Paleo-Pacific lithosphere.The Jiaojia Fault constrained the migration of ore-forming fluids and metals at the brittle-ductile transition.Fluid immiscibility,caused by episodic pressure drops,led to significant high-grade gold deposition in the giant Xincheng gold deposit.Liqiang Yang Jun Deng Ruipeng Guo Lin'nan Guo Zhongliang Wang Binghan Chen XudongWang 2016Geoscience Frontiers2016,7,3:14

19Theoretical and experimental study on relationship between stress-strain and temperature variation显示文摘Principle on temperature response to the stress-strain variation is fundamental to the relationship between thermal radiation variation and stress-strain field. Current research indicates that temperature has a sensitive response to rock deformation under the condition of normal temperature background. However, the basic physical relationship between deformation and temperature variation is not clear and need to be investigated further. In this paper, principle on temperature response to stress-strain variation is studied in detail, based on thermodynamics, elastic strain theory, and experiments on both ideal material and rock. In the stage of elastic deformation, results indicate that: 1) temperature increment is positively correlated with volume strain variation. Temperature rises with hydrostatic pressure increase. In other words, temperature rises when the specimen is under the compressive state whereas temperature drops under the tensile state. 2) Pure shear deformation does not contribute to tempera- ture variation. Namely, shape change of specimen does not produce temperature variation. However, there exist the relative tensile area and the compressive one in the specimen under the state of pure shear. Temperature drops within the relative tensile area while temperature rises within the compressive areas during the process of loading.CHEN ShunYun LIU LiQiang LIU PeiXun MA Jin CHEN GuoQiang 2009Science China Earth Sciences2009,52,11:13
20Reconstruction of Ore-controlling Structures Resulting from Magmatic Intrusion into the Tongling Ore Cluster Area during the Yanshanian Epoch显示文摘摘要:Tongling 矿石簇区域经历了集中的压缩并且联系了在 Indosinian-Yanshanian 时代期间砍,它形成了一个箱子在 caprock 的控制矿石的褶层和差错系统。在 Yanshanian 时代的 magmatic 侵入导致了多相的液体的多级式的 unmixing,导致多层、宽范围、多种形式的式样描绘的矿化作用。在 Tongling 区域的 magmatic 侵入不仅供应了必要形成矿石的材料,而且重建控制矿石的结构根据下列五条阶层边界的趋势表面模拟:志留纪泥盆纪,泥盆纪含碳,含碳二叠,中间二叠上面二叠、二叠三叠纪。这模拟的结果证明那在那里存在在上面的部分和那些在的阶层之间的重要差别更低。而上面的趋势表面是 synform,更低的趋势表面是 antiform。另外,趋势迭加邻近的床边界出现(例如,志留纪泥盆纪边界在泥盆纪含碳的边界之上迭加) 证明更低的趋势表面总是上面穿透那。而且,不同迭加的趋势表面的穿透的部分的位置和取向是类似的并且根据地区性的 E-W-trending magmatic-metallogenic 带的分发显示出 E-W-trending 带的分发。基于阶层,结构的变丑机制,和地现象的机械性质的全面分析,看起来, stratal 趋势表面的特殊特征由于 magmatic 侵入源于 jacking 进一个 E-W-trending 地下室差错以前控制的 caprock。因此,主要控制矿石的结构,在地区性的水平压缩期间形成了,被形成矿石的岩浆的垂直 jacking 功能在 Yanshanian 时代期间重建,这被推出。在形成矿石的过程期间,岩浆的本地垂直 jacking,结合了地区性的水平压缩,在液体水管网络优化了广泛的环境并且加速了多相的液体的 unmixing 后面的 magmatic 炮兵阵地。Jacking 也加强了垂直、侧面的指导液体的结构,供应为多层的炮兵阵地和多相的液体的广阔运输的更合适的物理条件。DENG Jun WANG Qingfei YANG Liqiang GAO Bangfei HUANG Dinghua LIU Yah XU Hao JIANG Shaoqing 2007Acta Geologica Sinica(English Edition)2007,81,2:13
