| 1 | Erianin,a novel dibenzyl compound in Dendrobium extract,inhibits lung cancer cell growth and migration via calcium/calmodulin-dependent ferroptosis显示文摘Ferroptosis,a novel form of programmed cell death,is characterized by iron-dependent lipid peroxidation and has been shown to be involved in multiple diseases,including cancer.Stimulating ferroptosis in cancer cells may be a potential strategy for cancer therapy.Therefore,ferroptosis-inducing drugs are attracting more attention for cancer treatment.Here,we showed that erianin,a natural product isolated from Dendrobium chrysotoxum Lindl,exerted its anticancer activity by inducing cell death and inhibiting cell migration in lung cancer cells.Subsequently,we demonstrated for the first time that erianin induced ferroptotic cell death in lung cancer cells,which was accompanied by ROS accumulation,lipid peroxidation,and GSH depletion.The ferroptosis inhibitors Fer-1 and Lip-1 but not Z-VAD-FMK,CQ,or necrostatin-1 rescued erianin-induced cell death,indicating that ferroptosis contributed to erianin-induced cell death.Furthermore,we demonstrated that Ca^(2+)/CaM signaling was a critical mediator of erianin-induced ferroptosis and that blockade of this signaling significantly rescued cell death induced by erianin treatment by suppressing ferroptosis.Taken together,our data suggest that the natural product erianin exerts its anticancer effects by inducing Ca^(2+)/CaMdependent ferroptosis and inhibiting cell migration,and erianin will hopefully serve as a prospective compound for lung cancer treatment. | Peng Chen Qibiao Wu Jiao Feng Lili Yan Yitian Sun Shuiping Liu Yu Xiang Mingming Zhang Ting Pan Xiaying Chen Ting Duan Lijuan Zhai Bingtao Zhai Wengang Wang Ruonan Zhang Bi Chen Xuemeng Han Yicong Li Liuxi Chen Ying Liu Xingxing Huang Ting Jin Wenzheng Zhang Hong Luo Xiaohui Chen Yongqiang Li Qiujie Li Guohua Li Qin Zhang Lvjia Zhuo Zuyi Yang Huifen Tang Tian Xie Xiaoping Ouyang Xinbing Sui | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 42 |
| 2 | Efficient indica and japonica rice identification based on the InDel molecular method:Its implication in rice breeding and evolutionary research显示文摘An efficient molecular method for the accurate and efficient identification of indica and japonica rice was created based on the poly-morphisms of insertion/deletion(InDel) DNA fragments obtained from the basic local alignment search tool(BLAST) to the entire genomic sequences of indica(93-11) and japonica rice(Nipponbare).The 45 InDel loci were validated experimentally by the polymerase chain reaction(PCR) and polyacrylamide gel electrophoresis(PAGE) in 44 typical indica and japonica rice varieties,including 93-11 and Nipponbare.A neutrality test of the data matrix generated from electrophoretic banding patterns of various InDel loci indicated that 34 InDel loci were strongly associated with the differentiation of indica and japonica rice.More extensive analyses involving cultivated rice varieties from 11 Asian countries,and 12 wild Oryza species with various origins confirmed that indica and japonica characteristics could accurately be determined via calculating the average frequency of indica-or japonica-specific alleles on different InDel loci across the rice genome.This method was named as the ''InDel molecular index' that combines molecular and statistical methods in determining the indica and japonica characteristics of rice varieties.Compared with the traditional methods based essentially on morphology,the InDel molecular index provides a very accurate,rapid,simple,and efficient method for identifying indica and japonica rice.In addition,the InDel index can be used to determine indica or japonica characteristics of wild Oryza species,which largely extends the utility of this method.The InDel molecular index provides a new tool for the effective selection of appropriate indica or japonica rice germplasm in rice breeding.It also offers a novel model for the study of the origin,evolution,and genetic differentiation of indica and japonica rice adapted to various environmental changes. | Bao-Rong Lu Xingxing Cai Xin Jin | 2009 | Progress in Natural Science:Materials International2009，19，10： | 40 |
| 3 | A review of recent advances in selective catalytic NO_x reduction reactor technologies显示文摘Research on NO_x treatment is extensive in recent years due to growing environmental awareness.Selective catalytic reduction(SCR) of NO_x,as a proven technology,offers higher NO_x control efficiency than many other NO_x treatment methods.The present work reviews the recent development of SCR reactor technologies.Firstly,catalysts and mechanism of different SCRs were briefly summarized.Different SCR reactors,e.g.structured reactor,fluidized bed reactor and moving bed reactor,were then discussed.As a more advanced technology,multifunctional reactors were also developed for SCR process and could be divided into two categories:decoupled adsorption-reaction process and combined SCR system.The mechanism and properties of these processes were discussed in detail.Some recommendations were given for the future work in SCR reactor design.SCR reactor technology for emerging energy processes was also addressed,such as oxyfuel combustion and biofuel conversion processes,which put forward new requirements for SCR technologies and also open new opportunities for advanced design of SCR reactors. | Xingxing Cheng Xiaotao T.Bi | 2014 | Particuology2014，12，5： | 23 |
| 4 | Cell–cell contact with proinflammatory macrophages enhances the immunotherapeutic effect of mesenchymal stem cells in two abortion models显示文摘Mesenchymal stem cells(MSCs),which are pluripotent cells with immunomodulatory properties,have been considered good candidates for the therapy of several immune disorders,such as inflammatory bowel diseases,concanavalin A-induced liver injury,and graft-versus-host disease.The embryo is a natural allograft to the maternal immune system.A successful pregnancy depends on the timely extinction of the inflammatory response induced by embryo implantation,followed by the switch to a tolerant immune microenvironment in both the uterus and the system.Excessive infiltration of immune cells and serious inflammatory responses are triggers for embryo rejection,which results in miscarriage.Here,we demonstrated that adoptive transfer of MSCs could prevent fetal loss in a lipopolysaccharide(LPS)-induced abortion model and immune response-mediated spontaneous abortion model.The immunosuppressive MSCs alleviated excessive inflammation by inhibiting CD4+T cell proliferation and promoting the decidual macrophage switch to M2 in a tumor necrosis factor-stimulated gene-6(TSG-6)-dependent manner.Cell-tocell contact with proinflammatory macrophages increased the TSG-6 production by the MSCs,thereby enhancing the suppressive regulation of T cells and macrophages.Moreover,proinflammatory macrophages in contact with the MSCs upregulated the expression of CD200 on the stem cells and facilitated the reprogramming of macrophages towards an anti-inflammatory skew through the interaction of CD200 with CD200R on proinflammatory macrophages.Therefore,the results demonstrate that a TSG-6-mediated paracrine effect,reinforced by cell-to-cell contact between MSCs and proinflammatory macrophages,is involved in the mechanism of MSC-mediated abortion relief through the induction of immune tolerance.Our study also indicates the potential application of MSCs in clinical recurrent miscarriages. | Yanhong Li Di Zhang Ling Xu Lin Dong Ji Zheng Yikong Lin Jiefang Huang Yanyun Zhang Yu Tao Xingxing Zang Dajin Li Meirong Du | 2019 | Cellular & Molecular Immunology2019，16，12： | 23 |

| 9 | Early Paleozoic granulite-facies metamorphism and anatexis in the northern West Qinling orogen: Monazite and zircon U-Pb geochronological constraints显示文摘In the northern West Qinling orogen(WQO), granulite-facies metamorphic rocks are recognized within the Qinling Complex. These rocks are composed of amphibole-bearing two-pyroxene granulite and garnet-sillimanite gneiss with widespread migmatitization. We investigate three granulite-facies samples and one leucosome sample from the Qinling Complex, which are suitable for U-Pb analyses of zircon and monazite. SHRIMP and LA-ICPMS U-Pb age dating of zircon and monazite from two pelitic granulites provides weighted mean ages of 430±4 Ma(MSWD=0.88) and 433±4 Ma(MSWD=0.27), respectively.Based on the petrographic characteristics and zircon CL imagery, we postulated a ca. 430 Ma metamorphic timing for the pelitic granulites. LA-ICPMS zircon U-Pb data from an amphibole two-pyroxene granulite sample reports two weighted mean age groups:424±3 Ma(MSWD=0.45) and 402±3 Ma(MSWD=1.4), which were interpreted as granulite-facies metamorphic and retrograde ages, respectively. LA-ICPMS U-Pb dating of zircons from the leucosome sample yields a weighted mean age of 426±2 Ma(MSWD=0.3), which is interpreted as the crystallization age of the leucosome. These data indicate that the West QOB experienced early Paleozoic granulite-facies metamorphism and anatexis similar to the East QOB. However, it remains unclear whether the early Paleozoic granulite facies metamorphism resulted from an arc setting created by the northward subduction of the Shangdan ocean or from a continental collisional orogenic event. | MAO XiaoHong ZHANG JianXin YU ShengYao LI YunShuai YU XingXing LU ZengLong | 2017 | Science China Earth Sciences2017，60，5： | 12 |

| 11 | Novel Water-Based Drilling and Completion Fluid Technology to Improve Wellbore Quality During Drilling and Protect Unconventional Reservoirs显示文摘The efficient exploration and development of unconventional oil and gas are critical for increasing the self-sufficiency of oil and gas supplies in China.However,such operations continue to face serious problems(e.g.,borehole collapse,loss,and high friction),and associated formation damage can severely impact well completion rates,increase costs,and reduce efficiencies.Water-based drilling fluids possess certain advantages over oil-based drilling fluids(OBDFs)and may offer lasting solutions to resolve the aforementioned issues.However,a significant breakthrough with this material has not yet been made,and major technical problems continue to hinder the economic and large-scale development of unconventional oil and gas.Here,the international frontier external method,which only improves drilling fluid inhibition and lubricity,is expanded into an internal-external technique that improves the overall wellbore quality during drilling.Bionic technologies are introduced into the chemical material synthesis process to imitate the activity of life.A novel drilling and completion fluid technique was developed to improve wellbore quality during drilling and safeguard formation integrity.Macroscopic and microscopic analyses indicated that in terms of wellbore stability,lubricity,and formation protection,this approach could outperform methods that use typical OBDFs.The proposed method also achieves a classification upgrade from environmentally protective drilling fluid to an ecologically friendly drilling fluid.The developed technology was verified in more than 1000 unconventional oil and gas wells in China,and the results indicate significant alleviation of the formation damage attributed to borehole collapse,loss,and high friction.It has been recognized as an effective core technology for exploiting unconventional oil and gas resources.This study introduces a novel research direction for formation protection technology and demonstrates that observations and learning from the natural world can provide an inexhaustible source of ideas and inspire the creation of original materials,technologies,and theories for petroleum engineering. | Guancheng Jiang Jinsheng Sun Yinbo He Kaixiao Cui Tengfei Dong Lili Yang Xukun Yang Xingxing Wang | 2022 | Engineering2022，，11： | 11 |
| 12 | First-principles design of spintronics materials显示文摘Spintronics is one of the most promising next generation information technology, which uses the spins of electrons as information carriers and possesses potential advantages of speeding up data processing, high circuit integration density, and low energy consumption. However, spintronics faces a number of challenges, including spin generation and injection, long distance spin transport, and manipulation and detection of spin orientation. In solving these issues, new concepts and spintronics materials were proposed one after another, such as half metals, spin gapless semiconductors, and bipolar magnetic semiconductors.Topological insulators can also be viewed as a special class of spintronics materials, with their surface states used for pure spin generation and transportation. In designing these spintronics materials, first-principles calculations play a very important role. This article attempts to give a brief review of the basic principles and theoretical design of these materials. Meanwhile, we also give some attentions to the antiferromagnetic spintronics, which is mainly based on antiferromagnets and has aroused much interest in recent years. | Xingxing Li Jinlong Yang | 2016 | National Science Review2016，3，3： | 10 |
| 13 | Semi-tightly coupled integration of multi-GNSS PPP and S-VINS for precise positioning in GNSS-challenged environments显示文摘Because of its high-precision,low-cost and easy-operation,Precise Point Positioning(PPP)becomes a potential and attractive positioning technique that can be applied to self-driving cars and drones.However,the reliability and availability of PPP will be significantly degraded in the extremely difficult conditions where Global Navigation Satellite System(GNSS)signals are blocked frequently.Inertial Navigation System(INS)has been integrated with GNSS to ameliorate such situations in the last decades.Recently,the Visual-Inertial Navigation Systems(VINS)with favorable complementary characteristics is demonstrated to realize a more stable and accurate local position estimation than the INS-only.Nevertheless,the system still must rely on the global positions to eliminate the accumulated errors.In this contribution,we present a semi-tight coupling framework of multi-GNSS PPP and Stereo VINS(S-VINS),which achieves the bidirectional location transfer and sharing in two separate navigation systems.In our approach,the local positions,produced by S-VINS are integrated with multi-GNSS PPP through a graph-optimization based method.Furthermore,the accurate forecast positions with S-VINS are fed back to assist PPP in GNSS-challenged environments.The statistical analysis of a GNSS outage simulation test shows that the S-VINS mode can effectively suppress the degradation of positioning accuracy compared with the INS-only mode.We also carried out a vehicle-borne experiment collecting multi-sensor data in a GNSS-challenged environment.For the complex driving environment,the PPP positioning capability is significantly improved with the aiding of S-VINS.The 3D positioning accuracy is improved by 49.0%for Global Positioning System(GPS),40.3%for GPS+GLOANSS(Global Navigation Satellite System),45.6%for GPS+BDS(BeiDou navigation satellite System),and 51.2%for GPS+GLONASS+BDS.On this basis,the solution with the semi-tight coupling scheme of multi-GNSS PPP/S-VINS achieves the improvements of 41.8-60.6%in 3D position-ing accuracy compared with the multi-GNSS PPP/INS solutions. | Xingxing Li Xuanbin Wang Jianchi Liao Xin Li Shengyu Li Hongbo Lyu | 2021 | Satellite Navigation2021，2，1： | 10 |
| 14 | Changes in palaeoproductivity of Genggahai Lake over the past 16 ka in the Gonghe Basin,northeastern Qinghai-Tibetan Plateau显示文摘Sequential samples of a 7.82-m sediment core from Genggahai Lake in the central Gonghe Basin,controlled with 12 accelerator mass spectrometry (AMS) 14 C dates,have been analysed for total organic carbon (TOC) and total nitrogen (TN) contents,carbon isotope of bulk organic matter (δ 13 C org),and carbonate content.Plant macrofossils and stem encrustations,derived mainly from the species of P.pectinatus,M.spicatum and Chara spp.,were identified,and they dominated the aquatic plant community of the lake.Alternations of plant macrofossils of Chara spp.and the vascular species reflect the changing productivity of the lake over time.In such a shallow lake,the carbonate content is highly related to photosynthesis of aquatic macrophytes and thus indirectly indicates variations in productivity,consistent with a quantitative estimate of palaeoproductivity.Based on these results,the palaeoproductivity history was reconstructed over the past ca.16 ka.The lake was formed or recharged at 15.3 cal ka BP,as indicated by aeolian sand deposits at the core base.A marked increase in palaeoproductivity occurred from 15.3 to 11.6 cal ka BP.Between 11.6 and 9.2 cal ka BP,a sharply increased water-level,modulated probably by the enhanced Asian summer monsoon,might have exceeded the optimum water depth for macrophyte vegetation,causing a marked decline in coverage of aquatic macrophytes and low palaeoproductivity.The palaeoproductivity appeared to be high in the early stage of the period from 9.2 to 7.4 cal ka BP,and then decreased at approximately 8.6 cal ka BP.The palaeoproductivity sustained an overall high level between 7.4 and 2.1 cal ka BP,and decreased gradually since 2.1 cal ka BP.Our results suggest that the variability of Genggahai Lake palaeoproductivity may be associated with fluctuations of the lake level controlled by the strength of the Asian summer monsoon,probably indicating changes in the Asian summer monsoon. | SONG Lei QIANG MingRui LANG LiLi LIU XingXing WANG Qin LI MingZhi | 2012 | Chinese Science Bulletin2012，57，20： | 9 |
| 15 | Rapid reconstitution of NK1 cells after allogeneic transplantation is associated with a reduced incidence of graft-versus-host disease显示文摘The balance between immunostimulation and immunoregulation in T cell immunity is achieved by maintaining specific ratios of Th1, Th2, Th3 and Tr1 cells. Here, we investigate levels of type 1(IFN-gamma; NK1), type 2(IL-13; NK2), type 3(TGF-beta;NK3) and regulatory(IL-10; NKr) cytokines in peripheral blood to assess the cytokine profiles of natural killer(NK) cells following human allogeneic hematopoietic stem cell transplantation(allo-HSCT). NK2 and NK3 cell expansion was observed after allo-HSCT; levels of NKr cells reached donor levels at day 15, though levels of NK1 cells were consistently lower than donor levels until day 60 after allo-HSCT. Multivariate analysis showed that a higher level of NK1 cells by day 15 was associated with a lower overall risk of acute graft-versus-host disease(GVHD)(HR 0.157, P=0.010) as well as II-IV acute GVHD(HR0.260, P=0.059). Furthermore, higher levels of NK1 cells by day 15 were correlated with lower rates of cytomegalovirus(CMV)reactivation(HR 0.040, 0.005–0.348, P=0.003). These results indicate that rapid reconstitution of NK cells, especially NK1 cells,can help prevent the development of GVHD as well as CMV reactivation after allogeneic transplantation. | Xingxing Yu Lingling Xu Yingjun Chang Xiaojun Huang Xiangyu Zhao | 2018 | Science China(Life Sciences)2018，61，8： | 9 |
| 16 | Diclofop-methyl affects microbial rhizosphere community and induces systemic acquired resistance in rice显示文摘Diclofop-methyl(DM),a widely used herbicide in food crops,may partly contaminate the soil surface of natural ecosystems in agricultural area and exert toxic effects at low dose to nontarget plants.Even though rhizosphere microorganisms strongly interact with root cells,little is known regarding their potential modulating effect on herbicide toxicity in plants.Here we exposed rice seedlings(Xiushui 63) to 100 μg/L DM for 2 to 8 days and studied the effects of DM on rice rhizosphere microorganisms,rice systemic acquired resistance(SAR) and rice-microorganisms interactions.The results of metagenomic 16 S rDNA Illumina tags show that DM increases bacterial biomass and affects their community structure in the rice rhizosphere.After DM treatment,the relative abundance of the bacterium genera Massilia and Anderseniella increased the most relative to the control.In parallel,malate and oxalate exudation by rice roots increased,potentially acting as a carbon source for several rhizosphere bacteria.Transcriptomic analyses suggest that DM induced SAR in rice seedlings through the salicylic acid(but not the jasmonic acid) signal pathway.This response to DM stress conferred resistance to infection by a pathogenic bacterium,but was not influenced by the presence of bacteria in the rhizosphere since SAR transcripts did not change significantly in xenic and axenic plant roots exposed to DM.The present study provides new insights on the response of rice and its associated microorganisms to DM stress. | Si Chen Xingxing Li Michel Lavoie Yujian Jin Jiahui Xu Zhengwei Fu Haifeng Qian | 2017 | Journal of Environmental Sciences2017，29，1： | 8 |
| 17 | Curcumenol triggered ferroptosis in lung cancer cells via lncRNA H19/miR-19b-3p/FTH1 axis显示文摘Curcumenol,an effective ingredient of Wenyujin,has been reported that exerted its antitumor potential in a few cancer types.However,the effect and molecular mechanism of curcumenol in lung cancer are largely unknown.Here,we found that curcumenol induced cell death and suppressed cell proliferation in lung cancer cells.Next,we demonstrated that ferroptosis was the predominant method that contributed to curcumenol-induced cell death of lung cancer in vitro and vivo for the first time.Subsequently,using RNA sequencing,we found that the long non-coding RNA H19(lncRNA H19)was significantly downregulated in lung cancer cells treated with curcumenol,when compared to untreated controls.Overexpression of lncRNA H19 eliminated the anticancer effect of curcumenol,while lncRNA H19 knockdown promoted ferroptosis induced by curcumenol treatment.Mechanistically,we showed that lncRNA H19 functioned as a competing endogenous RNA to bind to miR-19b-3p,thereby enhanced the transcription activity of its endogenous target,ferritin heavy chain 1(FTH1),a marker of ferroptosis.In conclusion,our data show that the natural product curcumenol exerted its antitumor effects on lung cancer by triggering ferroptosis,and the lncRNA H19/miR-19b-3p/FTH1 axis plays an essential role in curcumenol-induced ferroptotic cell death.Therefore,our findings will hopefully provide a valuable drug for treating lung cancer patients. | Ruonan Zhang Ting Pan Yu Xiang Mingming Zhang Han Xie Zimao Liang Bi Chen Cong Xu Jing Wang Xingxing Huang Qianru Zhu Ziming Zhao Quan Gao Chengyong Wen Wencheng Liu Weirui Ma Jiao Feng Xueni Sun Ting Duan Elaine Lai-Han Leung Tian Xie Qibiao Wu Xinbing Sui | 2022 | Bioactive Materials2022，7，7： | 8 |
| 18 | The computational fluid dynamic modeling of downwash flow field for a six-rotor UAV显示文摘The downwash flow field of the multi-rotor unmanned aerial vehicle(UAV), formed by propellers during operation, has a significant influence on the deposition, drift and distribution of droplets as well as the spray width of the UAV for plant protection. To study the general characteristics of the distribution of the downwash airflow and simulate the static wind field of multi-rotor UAVs in hovering state, a 3 D full-size physical model of JF01-10 six-rotor plant protection UAV was constructed using Solid Works. The entire flow field surrounding the UAV and the rotation flow fields around the six rotors were established in UG software. The physical model and flow fields were meshed using unstructured tetrahedral elements in ANSYS software.Finally, the downwash flow field of UAV was simulated.With an increased hovering height, the ground effect was reduced and the minimum current velocity increased initially and then decreased. In addition, the spatial proportion of the turbulence occupied decreased. Furthermore, the appropriate operational hovering height for the JF01-10 is considered to be 3 m. These results can be applied to six-rotor plant protection UAVs employed in pesticide spraying and spray width detection. | Yongjun ZHENG Shenghui YANG Xingxing LIU Jie WANG Tomas NORTON Jian CHEN Yu TAN | 2018 | Frontiers of Agricultural Science and Engineering2018，5，2： | 8 |
| 19 | Hydrogen sulfide, a signaling molecule in plant stress responses显示文摘Gaseous molecules, such as hydrogen sulfide(H_2S)and nitric oxide(NO), are crucial players in cellular and(patho)physiological processes in biological systems. The biological functions of these gaseous molecules, which were first discovered and identified as gasotransmitters in animals, have received unprecedented attention from plant scientists in recent decades. Researchers have arrived at the consensus that H_2S is synthesized endogenously and serves as a signaling molecule throughout the plant life cycle.However, the mechanisms of H_2S action in redox biology is still largely unexplored. This review highlights what we currently know about the characteristics and biosynthesis of H_2S in plants. Additionally,we summarize the role of H_2S in plant resistance to abiotic stress. Moreover, we propose and discuss possible redox-dependent mechanisms by which H_2S regulates plant physiology. | Jing Zhang Mingjian Zhou Heng Zhou Didi Zhao Cecilia Gotor Luis CRomero Jie Shen Zhenglin Ge Zhirong Zhang Wenbiao Shen Xingxing Yuan Yanjie Xie | 2021 | Journal of Integrative Plant Biology2021，63，1： | 8 |
