| 2 | A cyclic nucleotide-gated channel mediates cytoplasmic calcium elevation and disease resistance in rice显示文摘The transient elevation of cytoplasmic calcium is essential for pathogen-associated molecular pattern(PAMP)-triggered immunity(PTI).However,the calcium channels responsible for this process have remained unknown.Here,we show that rice CDSI(CELL DEATH and SUSCEPTIBLE to BLAST 1)encoding OsCNGC9;a cyclic nucleotide-gated channel protein,positively regulates the resistance to rice blast disease.We show that OsCNGC9 mediates PAMP-induced Ca2+influx and that this event is critical for PAMPs-triggered ROS burst and induction of PTI-related defense gene expression.We further show that a PTI related receptor-lih cytoplasmic kinase OsRLCK185 physically interacts with and phosphorylates OsCNGC9 to activate its channel activity.Our results suggest a signaling cascade linking pattern recognition to calcium channel activation,which is required for initiation of PTI and disease resistance in rice. | Jiachang Wang Xi Liu An Zhang Yulong Ren Fuqing Wu Gang Wang Yang Xu Cailin Lei Shanshan Zhu Tian Pan Yongfei Wang Huan Zhang Fan Wang Yan-Qiu Tan Yupeng Wang Xin Jin Sheng Luo Chunlei Zhou Xiao Zhang Jinling Liu Shuai Wang Lingzhi Meng Yihua Wang Xi Chen Qibing Lin Xin Zhang Xiuping Guo Zhijun Cheng Jiulin Wang Yunlu Tian Shijia Liu Ling Jiang Chuanyin Wu Ertao Wang Jian-Min Zhou Yong-Fei Wang Haiyang Wang Jianmin Wan | 2019 | Cell Research2019,29,10: | 13 |
| 3 | Transcriptional activation and phosphorylation of OsCNGC9 confer enhanced chilling tolerance in rice显示文摘Low temperature is a major environmental factor that limits plant growth and productivity.Although transient elevation of cytoplasmic calcium has long been recognized as a critical signal for plant cold tolerance,the calcium channels responsible for this process have remained largely elusive.Here we report that OsCNGC9,a cyclic nucleotide-gated channel,positively regulates chilling tolerance by mediating cytoplasmic calcium elevation in rice(Oryza sativa).We showed that the loss-of-function mutant of OsCNGC9 is defective in cold-induced calcium influx and more sensitive to prolonged cold treatment,whereas OsCNGC9 overexpression confers enhanced cold tolerance.Mechanistically,we demonstrated that in response to chilling stress,OsSAPK8,a homolog of Arabidopsis thaliana OST1,phosphorylates and activates OsCNGC9 to trigger Ca2+influx.Moreover,we found that the transcription of OsCNGC9 is activated by a rice dehydration-responsive element-binding transcription factor,OsDREB1A.Taken together,our results suggest that OsCNGC9 enhances chilling tolerance in rice through regulating cold-induced calcium influx and cytoplasmic calcium elevation. | Jiachang Wang Yulong Ren Xi Liu Sheng Luo Xiao Zhang Xin Liu Qibing Lin Shanshan Zhu Hua Wan Yang Yang Yu Zhang Bin Lei Chunlei Zhou Tian Pan Yongfei Wang Mingming Wu Ruonan jing Yang Xu Meng Han Fuqing Wu Cailin Lei Xiuping Guo Zhijun Cheng Xiaoming Zheng Yihua Wang Zhigang Zhao Ling Jiang Xin Zhang Yong-Fei Wang Haiyang Wang Jianmin Wan | 2021 | Molecular Plant2021,14,2: | 10 |
| 4 | Multi-Stage Hydrocarbon Accumulation and Formation Pressure Evolution in Sinian Dengying FormationCambrian Longwangmiao Formation, Gaoshiti-Moxi Structure, Sichuan Basin显示文摘Sichuan Basin is a typical superimposed basin, which experienced multi-phase tectonic movements, meanwhile Sinian–Cambrian underwent complex hydrocarbon accumulation processes, causing exploration difficulties in the past 60 years. Based on the microscopic evidence of fluid inclusions, combined with basin-modelling, this paper determines stages and time of hydrocarbon accumulation, reconstructs evolution of formation pressure and dynamic processes of hydrocarbon accumulation in Sinian Dengying Formation-Cambrian Longwangmiao Formation of Gaoshiti-Moxi structure. Three stages of inclusions are detected, including a stage of yellow-yellowgreen fluorescent oil inclusions, a stage of blue fluorescent oil-gas inclusions and a stage of non-fluorescent gas inclusions, reflecting the study area has experienced a series of complex hydrocarbon accumulation processes, such as formation of paleo-oil reservoirs, cracking of crude oil, formation of paleo-gas reservoirs and adjustment to present gas reservoirs, which occurred during 219–188, 192–146 and 168–0 Ma respectively. During the period of crude oil cracking, Dengying Formation-Longwangmiao Formation showed weak overpressure to overpressure characteristics, then after adjustment of paleo-gas reservoirs to present gas reservoirs, the pressure in Dengying Formation changed into overpressure but finally reduced to normal pressure system. However, due to excellent preservation conditions, the overpressure strength in Longwangmiao Formation only slightly decreased and was still kept to this day. | Juan Wu Shugen Liu Guozhi Wang Yihua Zhao Wei Sun Jinming Song Yanhong Tian | 2016 | Journal of Earth Science2016,27,5: | 8 |
| 5 | Regulating Zn Deposition via an Artificial Solid–Electrolyte Interface with Aligned Dipoles for Long Life Zn Anode显示文摘Aqueous zinc ion batteries show prospects for next-generation renewable energy storage devices.However,the practical applications have been limited by the issues derived from Zn anode.As one of serious problems,Zn dendrite growth caused from the uncontrollable Zn deposition is unfavorable.Herein,with the aim to regulate Zn deposition,an artificial solid–electrolyte interface is subtly engineered with a perovskite type material,BaTiO3,which can be polarized,and its polarization could be switched under the external electric field.Resulting from the aligned dipole in BaTiO3 layer,zinc ions could move in order during cycling process.Regulated Zn migration at the anode/electrolyte interface contributes to the even Zn stripping/plating and confined Zn dendrite growth.As a result,the reversible Zn plating/stripping processes for over 2000 h have been achieved at 1 mA cm^(−2) with capacity of 1 mAh cm−2.Furthermore,this anode endowing the electric dipoles shows enhanced cycling stability for aqueous Zn-MnO2 batteries.The battery can deliver nearly 100%Coulombic efficiency at 2 Ag^(−1) after 300 cycles. | Kai Wu Jin Yi Xiaoyu Liu Yang Sun Jin Cui Yihua Xie Yuyu Liu Yongyao Xia Jiujun Zhang | 2021 | Nano-Micro Letters2021,13,5: | 8 |
| 6 | Changes in nitrogen budget and potential risk to the environment over 20 years(1990–2010) in the agroecosystems of the Haihe Basin, China显示文摘The nitrogen balance can serve as an indicator of the risk to the environment of nitrogen loss from agricultural land. To investigate the temporal and spatial changes in agricultural nitrogen application and its potential threat to the environment of the Haihe Basin in China, we used a database of county-level agricultural statistics to calculate agricultural nitrogen input, output,surplus intensity, and use efficiency. Chemical fertilizer nitrogen input increased by 51.7% from1990 to 2000 and by 37.2% from 2000 to 2010, concomitant with increasing crop yields.Simultaneously, the nitrogen surplus intensity increased by 53.5% from 1990 to 2000 and by16.5% from 2000 to 2010, presenting a continuously increased environmental risk. Nitrogen use efficiency decreased from 0.46 in 1990 to 0.42 in 2000 and remained constant at 0.42 in 2010,partly due to fertilizer composition and type improvement. This level indicates that more than half of nitrogen inputs are lost in agroecosystems. Our results suggest that although the improvement in fertilizer composition and types has partially offset the decrease in nitrogen use efficiency, the environmental risk has still increased gradually over the past 20 years, along with the increase in crop yields and nitrogen application. It is important to achieve a better nitrogen balance through more effective management to significantly reduce the environmental risk,decrease nitrogen surplus intensity, and increase nitrogen use efficiency without sacrificing crop yields. | Mengmeng Zheng Hua Zheng Yingxia Wu Yi Xiao Yihua Du Weihua Xu Fei Lu Xiaoke Wang Zhiyun Ouyang | 2015 | Journal of Environmental Sciences2015,27,2: | 6 |
| 7 | Maternal risk factors for low birth weight for term births in a developed region in China:a hospital-based study of 55,633 pregnancies显示文摘Low birth weight (LBW) is an important risk factor for neonatal and infant mortality and morbidity in adults..However,no large scale study on the prevalence of LBW and related maternal risk factors in China has been published.To explore the effects of maternal factors on LBW for term birth in China,we conducted a hospital-based retrospective study of 55,633 Chinese pregnancy cases between 2001 and 2008.Maternal sociodemographic data,history of infertility and contraceptive use were obtained.Their medical status and diseases during pre-pregnancy were examined by physical examination at the first antenatal care visit.Maternal medical status before childbirth and pregnancy outcomes,including body weight,infant gender,multiple pregnancy and congenital anomalies,were recorded.Univariate and multivariate logistic regression,and linear regression were used to investigate the relationship between maternal factors and term LBW.The general incidence of term LBW was 1.70% in the developed area of China.After preliminary analysis using the univariate model,low primary education,anemia,hypertensive disorders,placental previa,oligohydramnios and premature rupture of membrane were predicted as independent factors of term LBW in the multivariate model.Furthermore,the decrease in annual frquencies of these risk factors were major causes of gradual decline in the incidence of LBW (from 2.43% in 2001 to 1.21% in 2008).The study demonstrated that among maternal factors,primary education,anemia and hypertensive disorders could contribute to LBW for term birth even in the most developed area of China. | Yihua Bian Zhan Zhang Qiao Liu Di Wu Shoulin Wang | 2013 | The Journal of Biomedical Research2013,27,1: | 6 |

| 9 | RIP1-dependent linear and nonlinear recruitments of caspase-8 and RIP3 respectively to necrosome specify distinct cell death outcomes显示文摘There remains a significant gap in our quantitative understanding of crosstalk between apoptosis and necroptosis pathways.By employing the SWATH-MS technique,we quantified absolute amounts of up to thousands of proteins in dynamic assembling/de-assembling of TNF signaling complexes.Combining SWATH-MS-based network modeling and experimental validation,we found that when RIP1 level is below~1000 molecules/cell(mpc),the cell solely undergoes TRADD-dependent apoptosis.When RIP1 is above~1000 mpc,pro-caspase-8 and RIP3 are recruited to necrosome respectively with linear and nonlinear dependence on RIP1 amount,which well explains the co-occurrence of apoptosis and necroptosis and the paradoxical obser-vations that RIP1 is required for necroptosis but its increase down-regulates necroptosis.Higher amount of RIP1(>~46,000 mpc)suppresses apoptosis,leading to necroptosis alone.The relation between RIP1 level and occurrence of necroptosis or total cell death is biphasic.Our study provides a resource for encoding the com-plexity of TNF signaling and a quantitative picture how distinct dynamic interplay among proteins function as basis sets in signaling complexes,enabling RIP1 to play diverse roles in governing cell fate decisions. | Xiang Li Chuan-Qi Zhong Rui Wu Xiaozheng Xu Zhang-Hua Yang Shaowei Cai Xiurong Wu Xin Chen Zhiyong Yin Qingzu He Dianjie Li Fei Xu Yihua Yan Hong Qi Changchuan Xie Jianwei Shuai Jiahuai Han | 2021 | Protein & Cell2021,12,11: | 5 |

| 11 | The novel gene BrMYB2,located on chromosome A07,with a short intron 1 controls the purple-head trait of Chinese cabbage(Brassica rapa L.)显示文摘Anthocyanins are important secondary metabolites in plants,but information on anthocyanin biosynthesis mechanisms in Chinese cabbage is limited.The new purple head Chinese cabbage cultivar 11S91 was analyzed,and an R2R3-MYB regulatory gene BrMYB2,located on chromosome A07,controlling the dominant purple-head trait was isolated.High expression of BrMYB2 generated a large accumulation of anthocyanins in 11S91,accompanied by highly upregulated BrTT8,BrF3′H,BrDFR1,BrANS1,BrUGTs,BrATs,and BrGSTs.11S91 inherited the purple locus from purple trait donor 95T2-5,and they shared consensus CDSs and gDNAs with those of BrMYB2(cBrMYB2 and gBrMYB2).Two SNPs in cBrMYB2 in 11S91 did not cause loss of function;in addition to several SNPs at both ends of intron 1,a large deletion had occurred in intron 1 of gBrMYB2 in 11S91.Genetic transformation of Arabidopsis showed that gBrMYB2 overexpression lines presented deeper purple color and higher expression than did the cBrMYB2 and cBrmyb2 lines,whereas gBrmyb2 with a long intron 1 did not cause the purple phenotype.We first show that BrMYB2 promotes anthocyanin biosynthesis under the control of the short intron 1 of gBrMYB2 in purple head Chinese cabbage,and gBrmyb2 with a long intron 1 represses anthocyanin production in white head Chinese cabbage.This evidence provides a new understanding of anthocyanin biosynthesis and purple germplasm generation in Brassica vegetables. | Qiong He Junqing Wu Yihua Xue Wenbin Zhao Ru Li Lugang Zhang | 2020 | Horticulture Research2020,7,1: | 4 |
| 12 | 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 |
| 13 | Animal exercise studies in cardiovascular research:Current knowledge and optimal design--A position paper of the Committee on Cardiac Rehabilitation,Chinese Medical Doctors’Association显示文摘Growing evidence has demonstrated exercise as an effective way to promote cardiovascular health and protect against cardiovascular diseases However,the underlying mechanisms of the beneficial effects of exercise have yet to be elucidated.Animal exercise studies are widely used to investigate the key mechanisms of exercise-induced cardiovascular protection.However,standardized procedures and well-established evaluation indicators for animal exercise models are needed to guide researchers in carrying out effective,high-quality animal studies using exercise to prevent and treat cardiovascular diseases.In our review,we present the commonly used animal exercise models in cardiovascular research and propose a set of standard procedures for exercise training,emphasizing the appropriate measurements and analysis in these chronic exercise models.We also provide recommendations for optimal design of animal exercise studies in cardiovascular research,including the choice of exercise models,control of exercise protocols,exercise at different stages of disease,and other considerations,such as age,sex,and genetic background.We hope that this position paper will promote basic research on exercise-induced cardiovascular protection and pave the way for successful translation of exercise studies from bench to bedside in the prevention and treatment of cardiovascular diseases. | Yihua Bei Lei Wang Rongjing Ding Lin Che Zhiqing Fan Wei Gao Qi Liang Shenghui Lin Suixin Liu Xiao Lu Yuqin Shen Guifu Wu Jian Yang Guolin Zhang Wei Zhao Lan Guo Junjie Xiao | 2021 | Journal of Sport and Health Science2021,10,6: | 2 |
| 14 | Numerical simulation of aerodynamic interactions among helicopter rotor,fuselage,engine and body of revolution显示文摘Numerical simulations of helicopter aerodynamic interactions among the main rotor,fuselage,engine inlets/outlets and slung loads of specific geometries have been conducted by very few researchers.In this work,the steady-state compressible Reynolds-averaged navier-stokes equations are solved to study the aerodynamic interactions among helicopter rotor,fuselage,engine and body of revolution in three cases,namely MI-171V5,ROBIN and UH-60A.In the first case,the downwash flow provided by the rotor of the uniform actuator disc model induces a significant deflection of the airflow velocity.The vortex-shaped distribution and evolution are discussed in detail.The engine can effectively change the overall flow field.The asymmetry of the flow field is observed by using the non-uniform actuator disc model.Qualitative analysis of ROBIN and quantitative computation of UH-60A show a consistent accuracy of the rotating reference frame model for rotor.The blade tip vortex motion of UH-60A is simulated and its radial position prediction is compared to empirical formulas.While performing flow of UH-60A in hover,both the fuselage normal force and rotor lift decrease because of the impact of the body of revolution. | CAO YiHua WU ZhenLong HUANG JunSen | 2014 | Science China(Technological Sciences)2014,57,6: | 2 |
| 15 | Magnetic Flux Leakage Course of Inner Defects and Its Detectable Depth显示文摘As a promising non-destructive testing(NDT)method,magnetic flux leakage(MFL)testing has been widely used for steel structure inspection.However,MFL testing still faces a great challenge to detect inner defects.Existing MFL course researches mainly focus on surface-breaking defects while that of inner defects is overlooked.In the paper,MFL course of inner defects is investigated by building magnetic circuit models,performing numerical simulations,and conducting MFL experiments.It is found that the near-surface wall has an enhancing effect on the MFL course due to higher permeability of steel than that of air.Further,a high-sensitivity MFL testing method consisting of Helmholtz coil magnetization and induction coil with a high permeability core is proposed to increase the detectable depth of inner defects.Experimental results show that inner defects with buried depth up to 80.0 mm can be detected,suggesting that the proposed MFL method has the potential to detect deeply-buried defects and has a promising future in the field of NDT. | Jianbo Wu Wenqiang Wu Erlong Li Yihua Kang | 2021 | Chinese Journal of Mechanical Engineering2021,34,4: | 2 |
| 16 | Analysis of Quenching Stresses in 35CrMo Axle显示文摘By using the finite element method(FEM), we comprehensively analyzed the fields of temperature, organization, and stress in 35CrMo train axles during the quenching process is conducted, and experimentally studied the formation and evolution of inner stresses in axles during the quenching process. The results show that in the quenching process, stresses on the axle surface change from tensile to compressive gradually, while stresses in the axle core change from compressive to tensile gradually. Heat stresses and the amount of martensitic transformation are all increased with the increase of cooling rate. As a result, the maximum instantaneous stresses in the axle are increased greatly when the cooling rate is increased with brine quenching. Large instantaneous tensile stress in the axle core with brine quenching is very likely to cause quench cracking and should be avoided. | 龚海 WU Yunxin FENG Xiaolei LI Yihua | 2016 | Journal of Wuhan University of Technology(Materials Science)2016,31,3: | 2 |
| 17 | Rice FLOURY ENDOSPERM 18 encodes a pentatricopeptide repeat protein required for 5′ processing of mitochondrial nad5 messenger RNA and endosperm development显示文摘Pentatricopeptide repeat(PPR) proteins, composing one of the largest protein families in plants,are involved in RNA binding and regulation of organelle RNA metabolism at the posttranscriptional level. Although several PPR proteins have been implicated in endosperm development in rice(Oryza sativa), the molecular functions of many PPRs remain obscure. Here, we identified a rice endosperm mutant named floury endosperm 18(flo18) with pleiotropic defects in both reproductive and vegetative development.Map-based cloning and complementation tests showed that FLO18 encodes a mitochondriontargeted P-type PPR protein with 15 PPR motifs.Mitochondrial function was disrupted in the flo18 mutant, as evidenced by decreased assembly of Complex I in the mitochondrial electron transport chain and altered mitochondrial morphology. Loss of FLO18 function resulted in defective 5′-end processing of mitochondrial nad5 transcripts encoding subunit 5 of nicotinamide adenine dinucleotide hydrogenase. These results suggested that FLO18 is involved in 5′-end processing of nad5 messenger RNA and plays an important role in mitochondrial function and endosperm development. | Mingzhou Yu Mingming Wu Yulong Ren Yihua Wang Jingfang Li Cailin Lei Yinglun Sun Xiuhao Bao Hongming Wu Hang Yang Tian Pan Yongfei Wang Ruonan Jing Mengyuan Yan Houda Zhang Lei Zhao Zhichao Zhao Xin Zhang Xiuping Guo Zhijun Cheng Bing Yang Ling Jiang Jianmin Wan | 2021 | Journal of Integrative Plant Biology2021,63,5: | 2 |
| 18 | Study on the influence of standoff distance on substrate damage under an abrasive water jet process by molecular dynamics simulation显示文摘The process of a cluster-containing water jet impinging on a monocrystalline silicon substrate was studied by molecular dynamics simulation. The results show that as the standoff distance increases, the jet will gradually diverge. As a result, the solidified water film between the cluster and the substrate becomes 'thicker' and 'looser'. The 'thicker' and 'looser' water film will then consume more input energy to achieve complete solidification, resulting in the stress region and the high-pressure region of the silicon substrate under small standoff distances to be significantly larger than those under large standoff distances. Therefore, the degree of damage sustained by the substrate will first experience a small change and then decrease quickly as the standoff distance increases. In summary, the occurrence and maintenance of complete solidification of the confined water film between the cluster and the substrate plays a decisive role in the level of damage formation on the silicon substrate. These findings are helpful for exploring the mechanism of an abrasive water jet. | Ruling CHEN Di ZHANG Yihua WU | 2018 | Friction2018,6,2: | 2 |
| 19 | On the Simulation of Fragmentation During the Process of Ceramic Tile Impacted by Blunt Projectile with SPH Method in LS-DYNA显示文摘Ceramics are extensively used in protective structures which are often subjected to projectile impacts.During an impact process of a ceramic target by a projectile,fragmentation occurs in both the target and the projectile.It is challenging to simulate such events and predict residual mass and velocity of the projectile.In this work,we attempt to use smoothed particle hydrodynamics(SPH)in LS-DYNA to reproduce fragmentation of the target and the projectile and predict residual mass and velocity of the projectile during a projectile impact of a ceramic target.SPH models for an alumina ceramic tile impacted by a blunt tungsten heavy alloy projectile are established.SPH simulation results of residual mass and velocity of the projectile as well as ejecta and bulge movements of the ceramic tile are obtained and compared with experimental data and simulation results of other numerical approaches.It is found that SPH simulation can properly reproduce the impact fragmentation of the target and the projectile,and shows advantages over existing numerical approaches in the prediction accuracy of residual mass and velocity.Moreover,effects of some numerical aspects of SPH,including particle spacing,contact treatment and parameters in artificial viscosity and smoothing length,on simulation results are identified.A simple approach using identical smoothing length and balanced artificial viscosity is proposed to reduce particle spacing sensitivity.The observed parametric effects and the proposed approach will provide guidance to set appropriate parameters values for SPH simulation of impact fragmentation. | Yihua Xiao Hecheng Wu Xuecheng Ping | 2020 | Computer Modeling in Engineering & Sciences2020,,3: | 2 |
