| 6 | Polymorphisms of MTHFD,plasma homocysteine levels, and risk of gastric cancer in ahigh-risk Chinese population显示文摘Purpose:Accumulative evidence suggests that folate has a protective effect on gastric cancer. The methylenetetrahyd-rofolate dlehydrogenase(MTHFD) plays an important role in folate and homocysteine metabolisms, and polymorphisms of MTHFD may result in disturbance of the folate-mediated homocysteine pathway. The aim of this study is to test the hypothesis that genetic variants of MTHFD and plasma homocysteine levels are associated with risk of gastric cancer and modulated by genotypes of methylenetetrahydrofolate reductase(MTHFR). Experimental Design: We genotyped G1958A and T401C in MTHFD and C677T in MTHFR and detected total plasma homocysteine(tHcy) levels in a case-control study of 589 gastric cancer cases and 635 cancer-free controls in a high-risk Chinese population. Results:The variant genotypes of MTHFD 1958AA and 401CC were associated with a significantly increased risk of gastric canceradjusted odds ratio(OR), 2.05; 95% confidence interval(95% CI),1.34-3.13 for 1958AA; adjusted OR,1.43; 95% CI,1.14-1.80 for 401CC compared with 1958GG/GA and 401TT/TC genotypes, respectively. Both of the effects were more evident in the subjects carrying MTHFR 677CT/TT genotypes. The average tHcy level was significantly higher in gastric cancer cases than in controls(P < 0.01), and the upper quartile of tHcy (> 13.6 mu mol/L) was associated with an 82% significantly increased risk of gastric cancer, compared with the lowest quartile of tHcy(<= 8.0 pmol/L;adjusted OR,1.82; 95% CI,1.20-2.75). Conclusions:The strong associations between MTHFD variants and the plasma tHcy levels and gastric cancer risk suggest, for the first time, a possible gene-environment interaction between genetic variants of folate-metabolizing genes and high tHcy levels in gastric carcinogenesis. | Wang, L.

| 8 | A viscoelastic-plastic constitutive model with Mohr-Coulomb yielding criterion for sea ice dynamics显示文摘A new viscoelastic-plastic (VEP) constitutive model for sea ice dynamics was developed based on continuum mechanics. This modelconsists of four components: Kelvin-Vogit viscoelastic model, Mohr-Coulomb yielding criterion, associated normality flow rule forplastic rehololgy, and hydrostatic pressure. The numerical simulations for ice motion in an idealized rectangular basin were made usingsmoothed particle hydrodynamics (SPH) method, and compared with the analytical solution as well as those based on the modified vis-cous plastic(VP) model and static ice jam theory. These simulations show that the new VEP model can simulate ice dynamics accu-rately. The new constitutive model was further applied to simulate ice dynamics of the Bohai Sea and compared with the traditionalVP, and modified VP models. The results of the VEP model are compared better with the satellite remote images, and the simulated iceconditions in the JZ20-2 oil platform area were more reasonable. | JI Shunying SHEN Hung Tao WANG Zhilian SHEN H Hayley YUE Qianjin | 2005 | Acta Oceanologica Sinica2005,24,4: | 9 |

| 10 | Directly patterned substrate-free plasmonic “nanograter” structures with unusual Fano resonances显示文摘The application of three-dimensional(3D)plasmonic nanostructures as metamaterials(MMs),nano-antennas,and other devices faces challenges in producing metallic nanostructures with easily definable orientations,sophisticated shapes,and smooth surfaces that are operational in the optical regime and beyond.Here,we demonstrate that complex 3D nanostructures can be readily achieved with focused-ion-beam irradiation-induced folding and examine the optical characteristics of plasmonic“nanograter”structures that are composed of free-standing Au films.These 3D nanostructures exhibit interesting 3D hybridization in current flows and exhibit unusual and well-scalable Fano resonances at wavelengths ranging from 1.6 to 6.4 mm.Upon the introduction of liquids of various refractive indices to the structures,a strong dependence of the Fano resonance is observed,with spectral sensitivities of 1400 nm and 2040 nm per refractive index unit under figures of merit of 35.0 and 12.5,respectively,for low-order and high-order resonance in the near-infrared region.This work indicates the exciting,increasing relevance of similarly constructed 3D free-standing nanostructures in the research and development of photonics and MMs. | Ajuan Cui Zhe Liu Jiafang Li Tiehan H Shen Xiaoxiang Xia Zhiyuan Li Zhijie Gong Hongqiang Li Benli Wang Junjie Li Haifang Yang Wuxia Li Changzhi Gu | 2015 | Light(Science & Applications)2015,4,1: | 8 |

| 12 | Scale dependence of direct shear tests显示文摘Direct shear test has been widely used to measure the shear strength of soils and other particulate materials in industry because of its simplicity. However, the results can be dependent on the specimen size. The ASTM (American Society for Testing and Materials) publications suggest that for testing soils the shear box should be at least ten times the diameter of the largest particle and the height of the box should be no more than half of its diameter. These guidelines are empirically based. A series of two-dimensional numerical direct shear tests are performed to investigate this scaling effect. By analyzing the bulk friction, particle translation and rotation, percentage of sliding, average volume (area) and shear strain and the evolution of the shear band, we find that the traditional guidelines for direct shear tests are questionable. Scaling dependency of bulk friction on the property of granular materials is clearly present. Our current analysis points out that the scaling effects can vary significantly depending on the particle properties other than their sizes. Of all the parameters we observed, particle rotation appears to have a decisive correlation with the bulk friction. Formation of a shear band is universal. As the shearing progresses, particle rotation begins to concentrate near the shear plane. By defining the width of a shear band as the standard deviation of the distribution of translational gradient or the standard deviation of the distribution of particle rotation, quantitative evolutions of shear band are presented. Both measures of the shear band width dropped rapidly during pre-failure stage. After peak stress both measures begin to approach steady state as the bulk friction stabilizes to the residual stage. These observations suggest that structure formation inside the shear band controls the scaling effect. | ZHOU Qiang SHEN Hayley H HELENBROOK Brian T ZHANG HongWu | 2009 | Chinese Science Bulletin2009,54,23: | 6 |

| 14 | Characteristics of temporal-spatial parameters in quasi-solid-fluid phase transition of granular materials显示文摘The quasi-solid-fluid phase transition of granular materials is closely related to the shear rate and solid concentration in addition to their intrinsic properties. The contact duration and the coordination number are two important temporal-spatial parame-ters to describe the granular interaction in phase transition. In this study, characteristics of the contact duration and the coordination number associated with the transition processes are determined using a 3D discrete element model under different shear rates and concentrations. The resulting macroscopic stress and strain-rate relations are discussed. The temporal and spatial parameters provide a linkage between the macroscopic constitutive law and inter- particle micromechanics. | JI Shunying SHEN H Hayley | 2006 | Chinese Science Bulletin2006,51,6: | 5 |

| 17 | The Photochemical Study of HSA and BSA with Resonance Light Scattering and Fluorescence Spectra显示文摘The resonance light-scattering (RLS) of human serum albumin (HSA) and bovine serum albumin (BSA) is reported for the first time, and applied to study photochemical reaction of HSA and BSA. The fact of photocrosslinking self-association effect in HSA and BSA solutions is identified by the enhancement of RLS. The fluorescence quenching at about 350 um and 700 um proves that tryptophan (Trp) residues are one of the photochemical activity sites in HSA and BSA molecules. The Rayleigh scattering (RS) spectra of HSA and BSA that were neglected in fluorescence spectra before are found at about 296 um, 592 um and 888 um for the first time, and are of adventageous to studying the aggregation of HSA or BSA. The possible photochemical reaction mechanism is also proposed. | Liang, H Shen, XC Li, F Jiang, ZL | 2000 | Chinese Chemical Letters2000,11,3: | 4 |
| 18 | Ticagrelor inhibits the NLRP3 inflammasome to protect against inflammatory disease independent of the P2Y_(12 ) signaling pathway显示文摘Ticagrelor is the first reversibly binding oralP2Y_(12) receptor antagonist to inhibit platelet activation and has been approved by the Food and Drug Administration for the treatment of coronary artery disease. At present, the other pharmacological functions of ticagrelor remain poorly understood. The NOD-, LRR-, and pyrin domain-containing protein 3 (NLRP3) inflammasome plays a critical role in the innate immune system, but its excessive activation also contributes to the pathogenesis of complex diseases. In this study, we systematically examined the effects of ticagrelor on the NLRP3 inflammasome and found that ticagrelor inhibits NLRP3 inflammasome activation in macrophages independent of its classic inhibitory effect on theP2Y_(12) signaling pathway. Further mechanistic studies demonstrate that ticagrelor attenuates the oligomerization of apoptosis-associated speck-like protein containing a CARD (ASC) by blocking chloride efflux, an effect achieved through the degradation of chloride intracellular channel proteins (CLICs) and blockade of the translocation of CLICs to the plasma membrane. Moreover, experiments on lipopolysaccharide-induced sepsis and alum-induced peritonitis in mice confirmed that ticagrelor mitigates the severity of systemic inflammation independent ofP2Y_(12) receptor antagonism. Importantly, oral administration of ticagrelor rapidly and strongly inhibited NLRP3 inflammasome activation in peripheral blood mononuclear cells from patients with acute coronary syndrome. Overall, our study reveals a novel pharmacological function of ticagrelor in addition to its classic antiplatelet properties, which suggests that ticagrelor may serve as a potential therapeutic agent for use in NLRP3-associated diseases. | Bo Huang Yufeng Qian Shujun Xie Xianhua Ye Hanwen Chen Zhifeng Chen Lihuan Zhang Jinming Xu Hu Hu Shenglin Ma Paul Héroux Di Wang Han-Ming Shen Yihua Wu Dajing Xia | 2021 | Cellular & Molecular Immunology2021,18,5: | 3 |
