| 1 | Plant abiotic stress response and nutrient use efficiency显示文摘Abiotic stresses and soil nutrient limitations are major environmental conditions that reduce plant growth,productivity and quality.Plants have evolved mechanisms to perceive these environmental challenges,transmit the stress signals within cells as well as between cells and tissues,and make appropriate adjustments in their growth and development in order to survive and reproduce.In recent years,significant progress has been made on many fronts of the stress signaling research,particularly in understanding the downstream signaling events that culminate at the activation of stress-and nutrient limitation-responsive genes,cellular ion homeostasis,and growth adjustment.However,the revelation of the early events of stress signaling,particularly the identification of primary stress sensors,still lags behind.In this review,we summarize recent work on the genetic and molecular mechanisms of plant abiotic stress and nutrient limitation sensing and signaling and discuss new directions for future studies. | Zhizhong Gong Liming Xiong Huazhong Shi Shuhua Yang Luis R.Herrera-Estrella Guohua Xu Dai-Yin Chao Jingrui Li Peng-Yun Wang Feng Qin Jigang Li Yanglin Ding Yiting Shi Yu Wang Yongqing Yang Yan Guo Jian-Kang Zhu | 2020 | Science China(Life Sciences)2020，63，5： | 94 |

| 9 | Multimorbidity patterns and association with mortality in 0.5 million Chinese adults显示文摘Background:Few studies have assessed the relationship between multimorbidity patterns and mortality risk in the Chinese population.We aimed to identify multimorbidity patterns and examined the associations of multimorbidity patterns and the number of chronic diseases with the risk of mortality among Chinese middle-aged and older adults.Methods:We used data from the China Kadoorie Biobank and included 512,723 participants aged 30 to 79 years.Multimorbidity was defined as the presence of two or more of the 15 chronic diseases collected by self-report or physical examination at baseline.Multimorbidity patterns were identified using hierarchical cluster analysis.Cox regression was used to estimate the associations of multimorbidity patterns and the number of chronic diseases with all-cause and cause-specific mortality.Results:Overall,15.8%of participants had multimorbidity.The prevalence of multimorbidity increased with age and was higher in urban than rural participants.Four multimorbidity patterns were identified,including cardiometabolic multimorbidity(diabetes,coronary heart disease,stroke,and hypertension),respiratory multimorbidity(tuberculosis,asthma,and chronic obstructive pulmonary disease),gastrointestinal and hepatorenal multimorbidity(gallstone disease,chronic kidney disease,cirrhosis,peptic ulcer,and cancer),and mental and arthritis multimorbidity(neurasthenia,psychiatric disorder,and rheumatoid arthritis).During a median of 10.8 years of follow-up,49,371 deaths occurred.Compared with participants without multimorbidity,cardiometabolic multimorbidity(hazard ratios[HR]=2.20,95%confidence intervals[CI]:2.14-2.26)and respiratory multimorbidity(HR=2.13,95%CI:1.97-2.31)demonstrated relatively higher risks of mortality,followed by gastrointestinal and hepatorenal multimorbidity(HR=1.33,95%CI:1.22-1.46).The mortality risk increased by 36%(HR=1.36,95%CI:1.35-1.37)with every additional disease.Conclusion:Cardiometabolic multimorbidity and respiratory multimorbidity posed the highest threat on mortality risk and deserved particular attention in Chinese adults. | Junning Fan Zhijia Sun Canqing Yu Yu Guo Pei Pei Ling Yang Yiping Chen Huaidong Du Dianjianyi Sun Yuanjie Pang Jun Zhang Simon Gilbert Daniel Avery Junshi Chen Zhengming Chen Jun Lyu Liming Li On Behalf of the China Kadoorie Biobank Collaborative Group | 2022 | Chinese Medical Journal2022，，6： | 17 |
| 10 | Does flagship species tourism benefit conservation? A case study of the golden snub-nosed monkey in Shennongjia National Nature Reserve显示文摘Tourism has been widely used as a conservation strategy that directly compensates local people or management authorities, thereby contributing to development and creating incentives to preserve the landscape. Reserves or parks that are inhabited by flagship species may be able to generate more revenue through tourism than those without such species because flagship species have great potential for raising funds and creating publicity for conservation goals. In this paper, we examine flagship species tourism focused on observing the golden snub-nosed monkey (Rhinopithecus roxellana) in Shennongjia National Nature Reserve (SNNR). After the program was launched in 2006, both the number of tourists and amount of revenue received by SNNR increased as the general trends of tourism revenue in the country also increased. As a result, SNNR significantly increased rein- vestment in tourism and conservation infrastructure. Furthermore, after senior politicians visited the golden snub-nosed monkey, they abruptly changed their attitudes toward biological conservation, as indicated by an increase in both regular and additional funding for the species conservation. We conclude that flagship species tourism may not only generate revenue for conservation and management but also can improve officials' attitudes toward preserving biodiversity. However, it is important to ensure the continued safety and sustainability of such programs, from both the human and animal perspective, and we suggest stricter measures are introduced to reduce the risk of aerosol disease transmission from tourists to the monkeys. | XIANG ZuoFu YU Yang YANG Mei YANG JingYuan NIAO MingYao LIMing | 2011 | Chinese Science Bulletin2011，56，24： | 16 |
| 11 | A carbon-oxygen-bridged ladder-type building block for efficient donor and acceptor materials used in organic solar cells显示文摘A carbon-oxygen-bridged ladder-type donor unit(CO5) was invented and prepared via an ‘‘intramolecular demethanolization cyclization' approach. Its single crystal structure indicates enhanced planarity compared with the carbon-bridged analogue indacenodithiophene(IDT). Owing to the stronger electron-donating capability of CO5 than IDT, CO5-based donor and acceptor materials show narrower bandgaps. A donor-acceptor(D-A) copolymer donor(PCO5TPD) and an A-D-A nonfullerene acceptor(CO5IC) demonstrated higher performance than IDT-based counterparts, PIDTTPD and IDTIC, respectively. The better performance of CO5-based materials results from their stronger light-harvesting capability and higher charge-carrier mobilities. | Zuo Xiao Fan Liu Xinjian Geng Jianqi Zhang Shizhe Wang Yujun Xie Zhen Li Huai Yang Yongbo Yuan Liming Ding | 2017 | Science Bulletin2017，62，19： | 16 |
| 12 | Progress of the key materials for organic solar cells显示文摘Organic solar cells have attracted academic and industrial interests due to the advantages like lightweight,flexibility and roll-to-roll fabrication.Nowadays,18%power conversion efficiency has been achieved in the state-of-the-art organic solar cells.The recent rapid progress in organic solar cells relies on the continuously emerging new materials and device fabrication technologies,and the deep understanding on film morphology,molecular packing and device physics.Donor and acceptor materials are the key materials for organic solar cells since they determine the device performance.The past 25 years have witnessed an odyssey in developing high-performance donors and acceptors.In this review,we focus on those star materials and milestone work,and introduce the molecular structure evolution of key materials.These key materials include homopolymer donors,D-A copolymer donors,A-D-A small molecular donors,fullerene acceptors and nonfullerene acceptors.At last,we outlook the challenges and very important directions in key materials development. | Yang Tong Zuo Xiao Xiaoyan Du Chuantian Zuo Yuelong Li Menglan Lv Yongbo Yuan Chenyi Yi Feng Hao Yong Hua Ting Lei Qianqian Lin Kuan Sun Dewei Zhao Chunhui Duan Xiangfeng Shao Wei Li Hin-Lap Yip Zhengguo Xiaol Bin Zhang Qingzhen Bian Yuanhang Cheng Shengjian Liu Ming Cheng Zhiwen Jin Shangfeng Yang Liming Ding | 2020 | Science China Chemistry2020，63，6： | 15 |
| 13 | Antioxidant and immunomodulatory activities of a polysaccharide from Flammulina velutipes显示文摘OBJECTIVE: To evaluate the antioxidant and immunomodulatory activities of a unique polysaccharide from the medicinal fungus Flammulina velutipes in vitro.METHODS: Using water extraction and alcohol precipitation, crude polysaccharides were obtained. After purification by DEAE-cellulose 52 ion exchange chromatography and Sephacryl S-300 HR gel filtration chromatography, High performance liquid chromatography equipped with evaporative light-scattering detector, Infrared radiation and Nuclear magnetic resonance were used to evaluate the structure of the polysaccharide. Its immunomodulatory activity was measured by examining the production of nitric oxide(NO) and cytokine secretion, and via lymphocyte proliferation experiments. Its effects on the scavenging activities of hydroxyl radical, superoxide anion and reducing power were also measured.RESULTS: A water-soluble polysaccharide, Flammulina velutipes polysaccharide I-A(FVP I-A), was obtained with a molecular mass of 8.14×104Da determined by high performance gel permeation chromatography. An in vitro antioxidant assay indicated that FVP I-A could scavenge hydroxyl radical, superoxide anion and possessed reducing power and could largely promote NO production and augment the interleukin-1β, interleukin-6, and tumor necrosis factor-α secretion by RAW264.7 macrophages(P<0.05). Moreover, FVP I-A could promote lymphocyte proliferation(P<0.05), and synergistically enhance the augmentation of the proliferation of mouse lymphocytes by concanavalin A and lipopolysaccharides(P<0.01, P<0.05).CONCLUSION: The FVP I-A obtained from Flammulina velutipes possessed antioxidant activity and could enhance non-specific and specific immune responses in vitro. | Ming Wu Xia Luo Xiaoyan Xu Wei Wei Mengyao Yu Nan Jiang Liming Ye Zhirong Yang Xiaofan Fei | 2014 | Journal of Traditional Chinese Medicine2014，34，6： | 14 |
| 14 | Release of volatile organic compounds during bio-drying of municipal solid waste显示文摘Three treatments were tested to investigate the release concentrations of volatile organic compounds (VOCs) during the bio-drying of municipal solid waste (MSW) by the aerobic and combined hydrolytic-aerobic processes.Results showed that VOCs were largely released in the first 4 days of bio-drying and the dominant components were:dimethyl disulfide,dimethyl sulfide,benzene,2-butanone,limonene and methylene chloride.Thus,the combined hydrolytic-aerobic process was suggested for MSW bio-drying due to fewer aeration quantities in this phase when compared with the aerobic process,and the treatment strategies should base on the key properties of these prominent components.Malodorous sulfur compounds and terpenes were mainly released in the early phase of bio-drying,whereas,two peaks of release concentrations appeared for aromatics and ketones during bio-drying.Notably,for the combined hydrolytic-aerobic processes there were also high concentrations of released aromatics in the shift from hydrolytic to aerobic stages.High concentrations of released chlorinateds were observed in the later phase.For the VOCs produced during MSW bio-drying,i.e.,malodorous sulfur compounds,terpenes and chlorinateds,their release concentrations were mainly determined by production rates;for the VOCs presented initially in MSW,such as aromatics,their transfer and transport in MSW mainly determined the release concentrations. | Pinjing He,Jiafu Tang,Dongqing Zhang,Yang Zeng,Liming ShaoState Key Laboratory of Pollution Control and Resource Reuse,Key Laboratory of Yangtze River Water Environment,College of Environmental Science and Engineering,Tongji University,Shanghai 200092,China. | 2010 | Journal of Environmental Sciences2010，22，5： | 13 |

| 16 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 12 |

| 19 | The newly emerged SARS-Like coronavirus HCoV-EMC also has an “Achilles’ heel”: current effective inhibitor targeting a 3C-like protease显示文摘From the global outbreak of SARS-CoV caused infection disease in 2003,coronaviruses(CoVs)are known to be a great threat to the human health.Recently,a new SARS-like coronavirus,human betacoronavirus 2c EMC/2012(HCoV-EMC),has been identified and the appearance of this new CoV raises concerns that a new spread of CoV may occurs in the future.By solving the crystal structure of HCoV-EMC main protease with a wide-spectrum anti-CoV inhibitor N3,we confi rmed that that N3 blocks the function of HCoV-EMC main protease through a similar mechanism to other CoVs.Together with the good pharmaceutical features,N3 is conceivable to be effective to HCoV-EMC and other CoVs appearing in the future.These fi ndings make it convincing that CoVs will not be a threat to human health. | Zhilin Ren Liming Yan Ning Zhang Yu Guo Cheng Yang Zhiyong Lou Zihe Rao | 2013 | Protein & Cell2013，4，4： | 10 |
| 20 | Design and performance analysis of position-based impedance control for an electrohydrostatic actuation system显示文摘Electrohydrostatic actuator(EHA) is a type of power-by-wire actuator that is widely implemented in the aerospace industry for flight control, landing gears, thrust reversers, thrust vector control, and space robots. This paper presents the development and evaluation of positionbased impedance control(PBIC) for an EHA. Impedance control provides the actuator with compliance and facilitates the interaction with the environment. Most impedance control applications utilize electrical or valve-controlled hydraulic actuators, whereas this work realizes impedance control via a compact and efficient EHA. The structures of the EHA and PBIC are firstly introduced. A mathematical model of the actuation system is established, and values of its coefficients are identified by particle swarm optimization. This model facilitates the development of a position controller and the selection of target impedance parameters. A nonlinear proportional-integral position controller is developed for the EHA to achieve the accurate positioning requirement of PBIC. The controller compensates for the adverse effect of stiction, and a position accuracy of 0.08 mm is attained.Various experimental results are presented to verify the applicability of PBIC to the EHA. The compliance of the actuator is demonstrated in an impact test. | Yongling FU Xu HAN Nariman SEPEHRI Guozhe ZHOU Jian FU Liming YU Rongrong YANG | 2018 | Chinese Journal of Aeronautics2018，31，3： | 10 |
