1Cell-Mediated Immunity Imbalance in Patients with Intrahepatic Cholestasis of Pregnancy显示文摘Decidual lymphocytes may mediate fetal trophoblast recognition and regulate maternal immune reaction and play an essential role in the maintenance of normal pregnancy. The aim of this study was to compare the percentage of T cells, natural killer (NK) cells and natural killer T (NKT) cells within decidual parietalis of normal pregnant controls (NP) and patients with intraheptic cholestasis of pregnancy (ICP), and to investigate the production of interleukin-4 (IL-4), interferon-γ (IFN-γ) in the culture supernatant of decidual parietalis mononuclear cells (DPMCs). Compared with controls, the decidua parietalis from ICP were characterized with significant increased percentages of CD3-CD56+ cells, CD3+CD56+ cells, CD56+CD16+ cells, CD56+CD16- cells, CD56+NKG2D+ cells, and the significant decreased percentages of CD3+ cells, CD3+CD4+ cells. There were no differences found for the percentage of CD3+CD8+ cells, CD56+NKG2A+ cells between control and study group. In addition, the enhanced concentration of IFN-γ was presented in culture supernatant of DPMCs from ICP. It was suggested that the increased NK cells, NKT cells and the decreased T cells in the decidual parietalis and over-secretion of IFN-γ could be correlated with the pathophysiology of ICP patients.Bin Ling Fengqiu Yao Ying Zhou Zhengzheng Chen Guodong Shen Yuanyuan Zhu 2007Cellular & Molecular Immunology2007,4,1:19
2Establishment and Preliminary Application of a Rapid Fluorescent Focus Inhibition Test (RFFIT) for Rabies Virus显示文摘The World Health Organization (WHO) standard assay for determining levels of the rabies virus neutralization antibody (RVNA) is the rapid fluorescent focus inhibition test (RFFIT), which is used to evaluate the immunity effect after vaccination against rabies. For RFFIT, CVS-11 was used as the challenge virus, BSR cells as the adapted cells, and WHO rabies immunoglobulin (WHO STD) as the reference serum in this study. With reference to WHO and Pasteur RFFIT procedures, a micro-RFFIT procedure adapted to our laboratory was produced, and its specificity and reproducibility were tested. We tested levels of RVNA in human serum samples after immunization with different human rabies vaccines (domestic purified Vero cell rabies vaccine (PVRV) and imported purified chick embryo cell vaccine (PCECV)) using different regimens (Zagreb regimen and Essen regimen). We analyzed the levels of RVNA, and compared the immune efficacy of domestic PVRV and imported PCECV using different immunization regimens. The results showed that the immune efficacy of domestic PVRV using the Zagreb regimen was as good as that of the imported PCECV, but virus antibodies were generated more rapidly with the Zagreb regimen than with the Essen regimen. The RFFIT procedure established in our laboratory will enhance the comprehensive detection ability of institutions involved in rabies surveillance in China.Pengcheng Yu Xinjun Lv Xinxin Shen Qing Tang Guodong Liang 2013Virologica Sinica2013,28,4:11
3First dark matter search results from the PandaX-Ⅰ experiment显示文摘We report on the first dark-matter(DM)search results from PandaX-I,a low threshold dual-phase xenon experiment operating at the China JinPing Underground Laboratory.In the 37-kg liquid xenon target with 17.4 live-days of exposure,no DM particle candidate event was found.This result sets a stringent limit for low-mass DM particles and disfavors the interpretation of previously-reported positive experimental results.The minimum upper limit,3.7×10-44cm2,for the spin-independent isoscalar DM-particle-nucleon scattering cross section is obtained at a DM-particle mass of 49 GeV/c2at 90%confidence level.XIAO MengJiao XIAO Xiang ZHAO Li CAO XiGuang CHEN Xun CHEN YunHua CUI XiangYi FANG DeQing FU ChangBo GIBONI Karl L.

6Temperature-induced Lifshitz transition in topological insulator candidate HfTe_5显示文摘The ongoing discoveries and studies of novel topological quantum materials have become an emergent and important field of condensed matter physics.Recently,HfTe_5 ignited renewed interest as a candidate of a novel topological material.The single-layer HfTe_5 is predicted to be a two-dimensional large band gap topological insulator and can be stacked into a bulk that may host a temperature-driven topological phase transition.Historically,HfTe_5 attracted considerable interest for its anomalous transport properties characterized by a peculiar resistivity peak accompanied by a sign reversal carrier type.The origin of the transport anomaly remains under a hot debate.Here we report the first high-resolution laser-based angle-resolved photoemission measurements on the temperature-dependent electronic structure in HfTe_5.Our results indicated that a temperature-induced Lifshitz transition occurs in HfTe_5,which provides a natural understanding on the origin of the transport anomaly in HfTe_5.In addition,our observations suggest that HfTe_5 is a weak topological insulator that is located at the phase boundary between weak and strong topological insulators at very low temperature.Yan Zhang Chenlu Wang Guodong Liu Aiji Liang Lingxiao Zhao Jianwei Huang Qiang Gao Bing Shen Jing Liu Cheng Hu Wenjuan Zhao Genfu Chen Xiaowen Jia Li Yu Lin Zhao Shaolong He Fengfeng Zhang Shenjin Zhang Feng Yang Zhimin Wang Qinjun Peng Zuyan Xu Chuangtian Chen Xingjiang Zhou 2017Science Bulletin2017,62,13:4
7Surface Organic Modification of Fe_3O_4 Magnetic Nanoparticles显示文摘The surface organic modification of Fe_3O_4 nanoparticles with silane coupling reagent KH570 was studied. The modified and unmodified nanoparticles were characterized by FT-IR, XPS and TEM. The spectra of FT-IR and XPS revealed that KH570 was coated onto the surface of Fe3O4 nanoparticles to get Fe-O-Si bond and an organic coating layer also was formed. Fe3O4 nanoparticles were spheres partly with mean size of 18.8 nm studied by TEM, which was consistent with the result 17.9 nm calculated by Scherrer’s equation. KH570 was adsorbed on surface and formed chemistry bond to be steric hindrance repulsion which prevented nanoparticles from reuniting. Then glycol-based Fe_3O_4 magnetic liquids dispersed stably was gained.CUI Sheng SHEN Xiaodong LIN Benlan JIANG Guodong ZHANG Weihua 2008Journal of Wuhan University of Technology(Materials Science)2008,23,4:4
8High-performance solar-blind ultraviolet photodetector based on electrospun TiO2-ZnTiO3 heterojunction nano- wires显示文摘High-performance solar-blind UV (ultraviolet) photodetectors (PDs) based on low-dimension semiconducting nanostructures with high sensitivity, excellent cycle stability, and the ability to operate in harsh environments are critical for solar observations, space communication, UV astronomy, and missile tracking. In this study, TiO2-ZnTiO3 heterojunction nanowire-based PDs are successfully developed and used to detect solar-blind UV light. A photoconductive analysis indicates that the fabricated PDs are sensitive to UV illumination, with high sensitivity, good stability, and high reproducibility. Further analysis indicates that the rich existence of grain boundaries within the TiO2-ZnTiO3 nanowire can greatly decrease the dark current and recombination of the electron-hole pairs and thereby significantly increase the device's photosensitivity, spectra responsivity (1.1 ~ 106), and external quantum efficiency (4.3 ~ 108 %). Moreover, the PDs exhibit good photodetective performance with fast photoresponse and recovery and excellent thermal stability at temperatures as high as 175 ℃. According to these results, TiO2-ZnTiO3 heterojunction nanowires exhibit great potential for applications in high-performance optical electronics and PDs, particularly next-generation photodetectors with the ability to operate in harsh environments.Haining Chong Guodong Wei Huilin Hou Huijun Yang Minghui Shang Fengmei Gao Weiyou Yang Guozhen Shen 2015Nano Research2015,8,9:4

10Bench cutting tests and analysis for harvesting hemp stalk显示文摘As a study basis in the field of design and research of harvester prototype,bench cutting test is to provide best parameters for the cutter design.In order to obtain the optimal parameters of cutter of the hemp harvester,cutting tests on hemp stalk were conducted to examine the influences of different geometrical parameters(length and edge type)of blade,different cutting speeds and stalk feeding speeds of reciprocating single movable blade and reciprocating double movable blades on the cutting performances(cutting power,cutting quality and synthesis score)by using self-designed test bench.According to features of different test factors,multi-factors orthogonal test was applied to determine the best combination of blade length,blade edge type and number of movable blade.Then with these parameters fixed,the optimal parameters for the factors of cutting speed and stalk feeding speed were obtained by quadratic-regression rotatable orthogonal test.According to the test results,the best combination of hemp stalk cutting was that using cutter with reciprocating double movable blades of long(120 mm)and serrated-edge at cutting speed of 1.1704 m/s and stalk feeding speed of 0.7079 m/s.The tests and analysis results can be applied into subsequent related researches on hemp harvesters.Shen Cheng Zhang Bin Li Xianwang Yin Guodong Chen Qiaomin Xia Chunhua 2017International Journal of Agricultural and Biological Engineering2017,10,6:2
11Changes in compressed neurons from dogs with acute and severe cauda equina constrictions following intrathecal injection of brain-derived neurotrophic factor-conjugated polymer nanoparticles显示文摘This study established a dog model of acute multiple cauda equina constriction by experimental constriction injury (48 hours) of the lumbosacral central processes in dorsal root ganglia neurons. The repair effect of intrathecal injection of brain-derived neurotrophic factor with 15 mg encapsulated biodegradable poly(lactide-co-glycolide) nanoparticles on this injury was then analyzed. Dorsal root ganglion cells (L7) of all experimental dogs were analyzed using hematoxylin-eosin staining and immunohistochemistry at 1, 2 and 4 weeks following model induction. Intrathecal injection of brain-derived neurotrophic factor can relieve degeneration and inflammation, and elevate the expression of brain-derived neurotrophic factor in sensory neurons of compressed dorsal root ganglion. Simultaneously, intrathecal injection of brain-derived neurotrophic factor obviously improved neurological function in the dog model of acute multiple cauda equina constriction. Results verified that sustained intraspinal delivery of brain-derived neurotrophic factor encapsulated in biodegradable nanoparticles promoted the repair of histomorphology and function of neurons within the dorsal root ganglia in dogs with acute and severe cauda equina syndrome.Junming Tan Jiangang Shi Guodong Shi Yanling Liu Xiaohong Liu Chaoyang Wang Dechun Chen Shunming Xing Lianbing Shen Lianshun Jia Xiaojian Ye Hailong He Jiashun Li 2013Neural Regeneration Research2013,8,3:2
