2Role of Fas/FasL Pathway-mediated Alveolar Macrophages Releasing Inflammatory Cytokines in Human Silicosis显示文摘The role of Fas/Fas ligand (FasL) in mediating alveolar macrophage (AM)-derived inflammatory cytokines in 29 human lung silicosis patients and 6 controls was studied.It showed that the serum levels of IL-1β,TNF-α,IL-8,MIP-1α,MCP-1,and TGF-β1were higher in silicosis patients than in controls,and increased with the progression of silicosis except TGF-β1 and IL-8.TGF-β1,IL-8,MCP-1,MIP-1αwere efficiently down-regulated by anti-FasL antibody or caspase-8 inhibitor,indicating that Fas/FasL signaling promotes theYAO San Qiao HE Qin Cheng YUAN Ju Xiang CHEN Jie CHEN Gang LU Yao BAI Yu Ping ZHANG Chun Min YUAN Yang XU Ying Jun 2013Biomedical and Environmental Sciences2013,26,11:13
3Association of a SLC30A8 Genetic Variant with Monotherapy of Repaglinide and Rosiglitazone Effect in Newly Diagnosed Type 2 Diabetes Patients in China显示文摘Objective To investigate a potential relationship between Solute carrier family 30 (zinc transporter) member 8 (SLC30A8) rs13266634 variant and efficacy of rosiglitazone or repaglinide in treating newly diagnosed Chinese type 2 diabetes patients.Methods A total of 209 diabetic patients without any antihyperglycemic history were recruited and treated with repaglinide or rosiglitazone randomly for 48 weeks (104 and 105 patients,respectively).Anthropometric measurements and clinical laboratory tests were carried out before and after the treatment.An non-synonymous variant rs13266634 was genotyped by matrix-assisted laser desorption ionization-time of flight mass spectroscopy.Results Ninety-one patients in repaglinide group and ninety-three patients in rosiglitazone group completed the study.Δ value of homeostasis model assessment of beta cell function (HOMA-B)and Δ value of fasting proinsulin levels were statistically significant between three genotype groups (P=0.0149 and 0.0246,respectively) after rosiglitazone treatment.However,no genotype association was observed in the repaglinide or rosiglitazone group with other parameters.Conclusion The SLC30A8 variant was associated with the efficacy of insulin sensitizer monotherapy on insulin secretion in patients with newly diagnosed type 2 diabetes mellitus in Shanghai,China.JIANG Feng LI Qing HU Cheng ZHANG Rong WANG Cong Rong YU Wei Hui LU Jing Yi TANG Shan Shan BAO Yu Qian XIANG Kun San JIA Wei Ping 2012Biomedical and Environmental Sciences2012,25,1:8
4The effects of the guide field on the structures of electron density depletions in collisionless magnetic reconnection显示文摘Two-dimensional particle-in-cell simulations are performed to investigate the formation of electron density depletions in collisionless magnetic reconnection.In anti-parallel reconnection,the quadrupole structures of the out-of-plane magnetic field are formed,and four symmetric electron density depletion layers can be found along the separatrices due to the effects of magetic mirror.With the increase of the initial guide field,the symmetry of both the out-of-plane magnetic field and electron density depletion layers is distorted.When the initial guide field is sufficiently large,the electron density depletion layers along the lower left and upper right separatrices disappear.The parallel electric field in guide field reconnection is found to play an important role in forming such structures of the electron density depletion layers.The structures of the out-of-plane magnetic field By and electron depletion layers in anti-parallel and guide field reconnection are found to be related to electron flow or in-plane currents in the separatrix regions.In anti-parallel reconnection,electrons flow towards the X line along the separatrices,and are directed away from the X line along the magnetic field lines just inside the separatrices.In guide field reconnection,electrons can only flow towards the X line along the upper left and lower right separatrices due to the existence of the parallel electric field in these regions.LU San LU QuanMing CAO Yang HUANG Can XIE JinLin WANG Shui 2011Chinese Science Bulletin2011,56,1:8
5Electron dynamics in collisionless magnetic reconnection显示文摘Magnetic reconnection provides a physical mechanism for fast energy conversion from magnetic energy to plasma kinetic energy. It is closely associated with many explosive phenomena in space plasma, usually collisionless in character. For this reason, researchers have become more interested in collisionless magnetic reconnection. In this paper, the various roles of electron dynamics in collisionless magnetic reconnection are reviewed. First, at the ion inertial length scale, ions and electrons are decoupled. The resulting Hall effect determines the reconnection electric field. Moreover, electron motions determine the current system inside the reconnection plane and the electron density cavity along the separatrices. The current system in this plane produces an out-of-plane magnetic field. Second, at the electron inertial length scale, the anisotropy of electron pressure determines the magnitude of the reconnection electric field in this region. The production of energetic electrons, which is an important characteristic during magnetic reconnection, is accelerated by the reconnection electric field. In addition, the different topologies, temporal evolution and spatial distribution of the magnetic field affect the accelerating process of electrons and determine the final energy of the accelerated electrons. Third, we discuss results from simulations and spacecraft observations on the secondary magnetic islands produced due to secondary instabilities around the X point, and the associated energetic electrons. Furthermore, progress in laboratory plasma studies is also discussed in regard to electron dynamics during magnetic reconnection. Finally, some unresolved problems are presented.LU QuanMing WANG RongSheng XIE JinLin HUANG Can LU San WANG Shui 2011Chinese Science Bulletin2011,56,12:8
6Advancement toward Polymer Electrolyte Membrane Fuel Cells at Elevated Temperatures显示文摘Elevation of operational temperatures of polymer electrolyte membrane fuel cells(PEMFCs)has been demonstrated with phosphoric acid-doped polybenzimidazole(PA/PBI)membranes.The technical perspective of the technology is simplified construction and operation with possible integration with,e.g.,methanol reformers.Toward this target,significant efforts have been made to develop acid-base polymer membranes,inorganic proton conductors,and organic-inorganic composite materials.This report is devoted to updating the recent progress of the development particularly of acid-doped PBI,phosphate-based solid inorganic proton conductors,and their composite electrolytes.Long-term stability of PBI membranes has been well documented,however,at typical temperatures of 160℃.Inorganic proton-conducting materials,e.g.,alkali metal dihydrogen phosphates,heteropolyacids,tetravalent metal pyrophosphates,and phosphosilicates,exhibit significant proton conductivity at temperatures of up to 300℃ but have so far found limited applications in the form of thin films.Composite membranes of PBI and phosphates,particularly in situ formed phosphosilicates in the polymer matrix,showed exceptionally stable conductivity at temperatures well above 200℃.Fuel cell tests at up to 260℃ are reported operational with good tolerance of up to 16%CO in hydrogen,fast kinetics for direct methanol oxidation,and feasibility of nonprecious metal catalysts.The prospect and future exploration of new proton conductors based on phosphate immobilization and fuel cell technologies at temperatures above 200℃ are discussed.Jin Zhang David Aili Shanfu Lu Qingfeng Li and San Ping Jiang 2020Research2020,,1:6
7Magnetotail dipolarization fronts and particle acceleration:A review显示文摘In this paper, the particle acceleration processes around magnetotail dipolarization fronts(DFs) were reviewed. We summarize the spacecraft observations(including Cluster, THEMIS, MMS) and numerical simulations(including MHD, testparticle, hybrid, LSK, PIC) of these processes. Specifically, we(1) introduce the properties of DFs at MHD scale, ion scale, and electron scale,(2) review the properties of suprathermal electrons with particular focus on the pitch-angle distributions,(3)define the particle-acceleration process and distinguish it from the particle-heating process,(4) identify the particle-acceleration process from spacecraft measurements of energy fluxes, and(5) quantify the acceleration efficiency and compare it with other processes in the magnetosphere(e.g., magnetic reconnection and radiation-belt acceleration processes). We focus on both the acceleration of electrons and ions(including light ions and heavy ions). Regarding electron acceleration, we introduce Fermi,betatron, and non-adiabatic acceleration mechanisms;regarding ion acceleration, we present Fermi, betatron, reflection, resonance, and non-adiabatic acceleration mechanisms. We also discuss the unsolved problems and open questions relevant to this topic, and suggest directions for future studies.Huishan FU Elena EGRIGORENKO Christine GABRIELSE Chengming LIU San LU KJHWANG Xuzhi ZHOU Zhe WANG Fang CHEN 2020Science China Earth Sciences2020,63,2:4

12Regional brain structural abnormality in ischemic stroke patients:a voxel-based morphometry study显示文摘Our previous study used regional homogeneity analysis and found that activity in some brain areas of patients with ischemic stroke changed significantly.In the current study,we examined structural changes in these brain regions by taking structural magnetic resonance imaging scans of 11 ischemic stroke patients and 15 healthy participants,and analyzing the data using voxel-based morphometry.Compared with healthy participants,patients exhibited higher gray matter density in the left inferior occipital gyrus and right anterior white matter tract.In contrast,gray matter density in the right cerebellum,left precentral gyrus,right middle frontal gyrus,and left middle temporal gyrus was less in ischemic stroke patients.The changes of gray matter density in the middle frontal gyrus were negatively associated with the clinical rating scales of the Fugl-Meyer Motor Assessment(r=–0.609,P=0.047) and the left middle temporal gyrus was negatively correlated with the clinical rating scales of the nervous functional deficiency scale(r=–0.737,P=0.010).Our findings can objectively identify the functional abnormality in some brain regions of ischemic stroke patients.Ping Wu Yu-mei Zhou Fang Zeng Zheng-jie Li Lu Luo Yong-xin Li Wei Fan Li-hua Qiu Wei Qin Lin Chen Lin Bai Juan Nie San Zhang Yan Xiong Yu Bai Can-xin Yin Fan-rong Liang 2016Neural Regeneration Research2016,11,9:2
