| 1 | Pathogenic T-cells and inflammatory monocytes incite inflammatory storms in severe COVID-19 patients显示文摘Pathogenic human coronavirus infections,such as severe acute respiratory syndrome CoV(SARS-CoV)and Middle East respiratory syndrome CoV(MERS-CoV),cause high morbidity and mortality[1,2].Recently,a severe pneumonia-associated respiratory syndrome caused by a new coronavirus(SARS-CoV-2)was reported in December 2019 in the city of Wuhan,Hubei province,China[3-5],which was also named as pneumonia-associated respiratory syndrome(PARS)[6]and can cause coronavirus disease 2019(COVID-19)to seriously endanger human health. | Yonggang Zhou Binqing Fu Xiaohu Zheng Dongsheng Wang Changcheng Zhao Yingjie Qi Rui Sun Zhigang Tian Xiaoling Xu Haiming Wei | 2020 | National Science Review2020，7，6： | 54 |
| 2 | Efficiency and Inheritance of Targeted Mutagenesis in Maize Using CRISPR-Cas9显示文摘CRISPR/Cas(clustered regularly interspaced short palindromic repeats/CRISPR-associated proteins) is an adaptive immune system in bacteria and archaea to defend against invasion from foreign DNA fragments. Recently, it has been developed as a powerful targeted genome editing tool for a wide variety of species. However, its application in maize has only been tested with transiently expressed somatic cells or with a limited number of stable transgenic T0 plants. The exact efficiency and specificity of the CRISPR/Cas system in the highly complex maize genome has not been documented yet. Here we report an extensive study of the well-studied type II CRISPR-Cas9 system for targeted genome editing in maize, with the codon-optimized Cas9 protein and the short non-coding guide RNA generated through a functional maize U6 sn RNA promoter. Targeted gene mutagenesis was detected for 90 loci by maize protoplast assay, with an average cleavage efficiency of 10.67%. Stable knockout transformants for maize phytoene synthase gene(PSY1) were obtained. Mutations occurred in germ cells can be stably inherited to the next generation. Moreover, no off-target effect was detected at the computationally predicted putative off-target loci. No significant difference between the transcriptomes of the Cas9 expressed and non-expressed lines was detected. Our results confirmed that the CRISPR-Cas9 could be successfully applied as a robust targeted genome editing system in maize. | Jinjie Zhu Ning Song Silong Sun Weilong Yang Haiming Zhao Weibin Song Jinsheng Lai | 2016 | Journal of Genetics and Genomics2016，43，1： | 12 |
| 3 | High-performance PVDF-HFP based gel polymer electrolyte with a safe solvent in Li metal polymer battery显示文摘Poly(vinylidenefluoride-co-hexafluoropropylene)(PVDF-HFP)based gel polymer electrolytes are widely studied owing to their electrochemical stability and high dielectric constant.However,most gel polymer electrolytes show unsatisfied safety and interface compatibility due to excessive absorption of volatile and flammable liquid solvents.Herein,by using a safe solvent(N-methyl-2-pyrrolidone)with higher boiling(203℃)and flash points(95℃),we initiatively fabricate a flexible PVDF-HFP based gel polymer electrolyte.The obtained gel polymer electrolyte demonstrates a high ionic conductivity of 7.24×10^−4 S cm−1,an electrochemical window of 5.2 V,and a high lithium transference number of 0.57.As a result,the synthesized polymer electrolyte exhibits a capacity retention of 70%after 500 cycles at 0.5 C,and a discharge capacity of 86 mAh g−1 even at a high current rate of 10 C for LiFePO4 based Li metal batteries.Moreover,a stable Li plating/stripping for more than 500 h is achieved under 0.1 mAh at both room temperature and 70℃.Our results indicate that the PVDF-HFP polymer electrolyte is promising for manufacturing safe and high-performance Li metal polymer batteries. | Jing Jie Yulong Liu Lina Cong Bohao Zhang Wei Lu Xinming Zhang Jun Liu Haiming Xie Liqun Sun | 2020 | Journal of Energy Chemistry2020，29，10： | 10 |

| 5 | Assessment of the Ecological Security in the Three Gorges Reservoir Area by Using the Ecological Footprint Method显示文摘The ecological footprint concept and its calculation models are useful for the measurement of the sustainable level of social and economic development.The ecological security situation of the Three Gorges Reservoir Area(TGRA) was evaluated using this concept in this study.The construction of the Three Gorges Reservoir has led to the change in the ecology and immigration status of TGRA.The ecological footprint method is an important means to study the regional ecological security.Our results suggested that,by excluding the areas for biodiversity conservation(12% of the total land),the ecological footprint per capita was 0.57895 ha,which exceeded the ecological carrying capacity in TGRA.The total ecological deficit was found to be 11,522,193.34 ha,accounting for 95.02% of the ecological carrying capacity.These findings suggested that the ecological security of TGRA was not good.In order to compensate for the ecological deficit,it was essential to introduce natural resources from other regions. | WANG Haiming WANG Hai'e SUN Hongyang WANG Xiaolan LIAO Xiaoyong CHEN Zhijian LI Xianwei | 2012 | Journal of Mountain Science2012，9，6： | 9 |
| 6 | Gentiopicroside targets PAQR3 to activate the PI3K/AKT signaling pathway and ameliorate disordered glucose and lipid metabolism显示文摘The obstruction of post-insulin receptor signaling is the main mechanism of insulin-resistant diabetes.Progestin and adipoQ receptor 3(PAQR3),a key regulator of inflammation and metabolism,can negatively regulate the PI3 K/AKT signaling pathway.Here,we report that gentiopicroside(GPS),the main bioactive secoiridoid glycoside of Gentiana manshurica Kitagawa,decreased lipid synthesis and increased glucose utilization in palmitic acid(PA) treated HepG2 cells.Additionally,GPS improved glycolipid metabolism in streptozotocin(STZ) treated high-fat diet(HFD)-induced diabetic mice.Our findings revealed that GPS promoted the activation of the PI3 K/AKT axis by facilitating DNA-binding protein 2(DDB2)-mediated PAQR3 ubiquitinated degradation.Moreover,results of surface plasmon resonance(SPR),microscale thermophoresis(MST) and thermal shift assay(TSA) indicated that GPS directly binds to PAQR3.Results of molecular docking and cellular thermal shift assay(CETSA) revealed that GPS directly bound to the amino acids of the PAQR3 NH2-terminus including Leu40,Asp42,Glu69,Tyr125 and Ser129,and spatially inhibited the interaction between PAQR3 and the PI3 K catalytic subunit(P110α) to restore the PI3 K/AKT signaling pathway.In summary,our study identified GPS,which inhibits PAQR3 expression and directly targets PAQR3 to restore insulin signaling pathway,as a potential drug candidate for the treatment of diabetes. | Haiming Xiao Xiaohong Sun Zeyuan Lin Yan Yang Meng Zhang Zhanchi Xu Peiqing Liu Zhongqiu Liu Heqing Huang | 2022 | Acta Pharmaceutica Sinica B2022，12，6： | 7 |
| 7 | THERMAL SHOCK OF SEMI-INFINITE BODY WITH MULTI-PULSED INTENSE LASER RADIATION显示文摘In order to investigate the thermal shock and the heat conduction property of a target under multi-pulsed laser radiation,analytic expressions of both temperature and thermal stress fields in the target are deduced on the basis of the non-Fourier conduction law and the thermo-elastic theory.Taking a stainless steel target as an example,we can solve the analytic expressions under appropriate boundary conditions by using the finite difference method and MATLAB software,and then reveal the evolution law of both surplus temperature and thermal stress in the target.The results indicate that the temperature curves in the target irradiated by a multi-pulsed laser take on a delayed character in different sections away from the boundary,which is only affected by its relaxation time.The front of the stress wave is very steep in the non-Fourier numerical solutions,which presents an obvious thermal shock,so it is necessary to consider the non-Fourier effect of semi-infinite body under the high energy laser radiation. | Haiming Huang 1 Fang Su Yue Sun(Institute of Engineering Mechanics,Beijing Jiaotong University,Beijing 100044,China) | 2010 | Acta Mechanica Solida Sinica2010，23，2： | 7 |
| 8 | Defective Kernel 39 encodes a PPR protein required for seed development in maize显示文摘RNA editing is a posttranscriptional process that is important in mitochondria and plastids of higher plants. All RNA editing-specific trans-factors reported so far belong to PLS-class of pentatricopeptide repeat(PPR)proteins. Here, we report the map-based cloning and molecular characterization of a defective kernel mutant dek39 in maize. Loss of Dek39 function leads to delayed embryogenesis and endosperm development, reduced kernel size, and seedling lethality. Dek39 encodes an E subclass PPR protein that targets to both mitochondria and chloroplasts, and is involved in RNA editing in mitochondrial NADH dehydrogenase3(nad3) at nad3-247 and nad3-275. C-to-U editing of nad3-275 is not conserved and even lost in Arabidopsis, consistent with the idea that no close DEK39 homologs are present in Arabidopsis. However, the amino acids generated by editing nad3-247 and nad3-275 are highly conserved in many other plant species, and the reductions of editing at these two sites decrease the activity of mitochondria NADH dehydrogenase complex I,indicating that the alteration of amino acid sequence is necessary for Nad3 function. Our results indicate that Dek39 encodes an E sub-class PPR protein that is involved in RNA editing of multiple sites and is necessary for seed development of maize. | Xiaojie Li Wei Gu Silong Sun Zongliang Chen Jing Chen Weibin Song Haiming Zhao Jinsheng Lai | 2018 | Journal of Integrative Plant Biology2018，60，1： | 6 |
| 9 | Effects of soil nutrients and climate factors on belowground biomass in an alpine meadow in the source region of the Yangtze-Yellow rivers, Tibetan Plateau of China显示文摘Improving our knowledge of the effects of environmental factors(e.g.soil conditions,precipitation and temperature) on belowground biomass in an alpine grassland is essential for understanding the consequences of carbon storage in this biome.The object of this study is to investigate the relative importance of soil nutrients and climate factors on belowground biomass in an alpine meadow in the source region of the Yangtze and Yellow rivers,Tibetan Plateau.Soil organic carbon(SOC),total nitrogen(TN) and total phosphorous(TP) contents and belowground biomass were measured at 22 sampling sites across an alpine meadow on the Tibetan Plateau.We analyzed the data by using the redundancy analysis to determine the main environmental factors affecting the belowground biomass and the contribution of each factor.The results showed that SOC,TN and TP were the main factors that influenced belowground biomass,and the contribution of SOC,TN and TP on biomass was in the range of 47.87%–72.06% at soil depths of 0–30 cm.Moreover,the combined contribution of annual mean temperature(AMT) and mean annual precipitation(MAP) on belowground biomass ranged from 0.92% to 4.10%.A potential mechanism for the differences in belowground biomass was caused by the variations in soil nitrogen and phosphorous,which were coupled with SOC.A significant correlation was observed between MAP and soil nutrients(SOC,TN and TP) at the soil depth of 0–10 cm(P<0.05).We concluded that precipitation is an important driving force in regulating ecosystem functioning as reflected in variations of soil nutrients(SOC,TN and TP) and dynamics of belowground biomass in alpine grassland ecosystems. | WANG Haiming SUN Jian LI Weipeng WU Jianbo CHEN Youjun LIU Wenhui | 2016 | Journal of Arid Land2016，8，6： | 5 |
| 10 | “Polymer-in-ceramic” based poly(ε-caprolactone)/ceramic composite electrolyte for all-solid-state batteries显示文摘Inspired by the concept of 'polymer-in-ceramic',a composite poly(ε-caprolactone)(PCL)/ceramic containing LiTFSI is prepared and investigated as a solid electrolyte for all-solid-state batteries.The composite with the optimum concentration of 45 wt% LiTFSI and 75 wt% Li1.5Al0.5Ge1.5(PO4)3(LAGP,NASICON-type structure) exhibits a high ionic conductivity(σi=0.17 mS cm-1) at 30℃,a transference number of 0.30,and is stable up to 5.0 V.The composite electrolyte is a flexible and self-standing membrane.Solid-state LiFePO4//Li batteries with this composite electrolyte demonstrate excellent cycling stability with high discharge capacity of 157 mA h g-1,high capacity retention of 96% and coulombic efficiency of 98.5% after 130 cycles at 30℃ and 0.1 C rate.These electrochemical properties are better than other PCL-based allsolid-lithium batteries,and validate the concept of 'polymer-in-ceramic' by avoiding the drawback of lower conductivity in prior 'polymer-in-ceramic' electrolyte at high concentration of the ceramic. | Bohao Zhang Yulong Liu Jia Liu Liqun Sun Lina Cong Fang Fu Alain Mauger Christian M.Julien Haiming Xie Xiumei Pan | 2021 | Journal of Energy Chemistry2021，30，1： | 4 |
| 11 | Enhanced ozonation degradation of atrazine in the presence of nano-ZnO: Performance, kinetics and effects显示文摘Enhanced ozonation degradation of atrazine(ATZ) with nano-ZnO(nZnO) as catalyst and the influences of the operational parameters have been investigated through semi-continuous experiments in this study. The results demonstrated that the combination of ozone(O_3) and nZnO showed an obvious synergetic effect and the ATZ degradation conformed to pseudo-first-order kinetics. An improvement of ATZ degradation efficiency by 41.8% and pseudo-first-order rate constant by more than a factor of four was obtained in the O_3/nZnO process after 5 min of reaction compared to O_3 alone. Meanwhile, the degradation efficiency of ATZ was gradually enhanced with increasing nZnO dosage and initial pH in the range from 3.0 to 8.0, and a higher amount of ATZ was degraded when the initial concentration of ATZ rose from 0.5 to 5 mg/L. Additionally, sulfate ion, chloride ion, nitrate ion and low concentrations of humic acid substances led to enhancement of the ATZ degradation. The notable decrease of ATZ removal efficiency observed in the presence of radical scavengers and the results of free radical tests indicated thatUOH is the dominant active radical species. The mechanism investigation demonstrated that the enhancement effect could be attributed to the introduction of nZnO,which could promote the utilization of O_3, enhance the formation of superoxide radical, and further accelerate the production of hydrogen peroxide and the generation of OH/O_2^-. | Xiangjuan Yuan Xuan Yan Haiming Xu Dongya Li Lei Sun Gang Cao Dongsheng Xia | 2017 | Journal of Environmental Sciences2017，29，11： | 4 |
| 12 | Machine Learning-Based Multi-Modal Information Perception for Soft Robotic Hands显示文摘This paper focuses on multi-modal Information Perception(IP)for Soft Robotic Hands(SRHs)using Machine Learning(ML)algorithms.A flexible Optical Fiber-based Curvature Sensor(OFCS)is fabricated,consisting of a Light-Emitting Diode(LED),photosensitive detector,and optical fiber.Bending the roughened optical fiber generates lower light intensity,which reflecting the curvature of the soft finger.Together with the curvature and pressure information,multi-modal IP is performed to improve the recognition accuracy.Recognitions of gesture,object shape,size,and weight are implemented with multiple ML approaches,including the Supervised Learning Algorithms(SLAs)of K-Nearest Neighbor(KNN),Support Vector Machine(SVM),Logistic Regression(LR),and the unSupervised Learning Algorithm(un-SLA)of K-Means Clustering(KMC).Moreover,Optical Sensor Information(OSI),Pressure Sensor Information(PSI),and Double-Sensor Information(DSI)are adopted to compare the recognition accuracies.The experiment results demonstrate that the proposed sensors and recognition approaches are feasible and effective.The recognition accuracies obtained using the above ML algorithms and three modes of sensor information are higer than 85 percent for almost all combinations.Moreover,DSI is more accurate when compared to single modal sensor information and the KNN algorithm with a DSI outperforms the other combinations in recognition accuracy. | Haiming Huang Junhao Lin Linyuan Wu Bin Fang Zhenkun Wen Fuchun Sun | 2020 | Tsinghua Science and Technology2020，25，2： | 4 |

| 14 | Skill Learning for Human-Robot Interaction Using Wearable Device显示文摘With the accelerated aging of the global population and escalating labor costs, more service robots are needed to help people perform complex tasks. As such, human-robot interaction is a particularly important research topic. To effectively transfer human behavior skills to a robot, in this study, we conveyed skill-learning functions via our proposed wearable device. The robotic teleoperation system utilizes interactive demonstration via the wearable device by directly controlling the speed of the motors. We present a rotation-invariant dynamicalmovement-primitive method for learning interaction skills. We also conducted robotic teleoperation demonstrations and designed imitation learning experiments. The experimental human-robot interaction results confirm the effectiveness of the proposed method. | Bin Fang Xiang Wei Fuchun Sun Haiming Huang Yuanlong Yu Huaping Liu | 2019 | Tsinghua Science and Technology2019，24，6： | 3 |

| 16 | Tocilizumab in patients with moderate or severe COVID-19: a randomized, controlled, open-label, multicenter trial显示文摘Tocilizumab has been reported to attenuate the“cytokine storm”in COVID-19 patients.We attempted to verify the effectiveness and safety of tocilizumab therapy in COVID-19 and identify patients most likely to benefit from this treatment.We conducted a randomized,controlled,open-label multicenter trial among COVID-19 patients.The patients were randomly assigned in a 1:1 ratio to receive either tocilizumab in addition to standard care or standard care alone.The cure rate,changes of oxygen saturation and interference,and inflammation biomarkers were observed.Thirty-three patients were randomized to the tocilizumab group,and 32 patients to the control group.The cure rate in the tocilizumab group was higher than that in the control group,but the difference was not statistically significant(94.12%vs.87.10%,rate difference 95%CI−7.19%–21.23%,P=0.4133).The improvement in hypoxia for the tocilizumab group was higher from day 4 onward and statistically significant from day 12(P=0.0359).In moderate disease patients with bilateral pulmonary lesions,the hypoxia ameliorated earlier after tocilizumab treatment,and less patients(1/12,8.33%)needed an increase of inhaled oxygen concentration compared with the controls(4/6,66.67%;rate difference 95%CI−99.17%to−17.50%,P=0.0217).No severe adverse events occurred.More mild temporary adverse events were recorded in tocilizumab recipients(20/34,58.82%)than the controls(4/31,12.90%).Tocilizumab can improve hypoxia without unacceptable side effect profile and significant influences on the time virus load becomes negative.For patients with bilateral pulmonary lesions and elevated IL-6 levels,tocilizumab could be recommended to improve outcome. | Dongsheng Wang Binqing Fu Zhen Peng Dongliang Yang Mingfeng Han Min Li Yun Yang Tianjun Yang Liangye Sun Wei Li Wei Shi Xin Yao Yan Ma Fei Xu Xiaojing Wang Jun Chen Daqing Xia Yubei Sun Lin Dong Jumei Wang Xiaoyu Zhu Min Zhang Yonggang Zhou Aijun Pan Xiaowen Hu Xiaodong Mei Haiming Wei Xiaoling Xu | 2021 | Frontiers of Medicine2021，15，3： | 2 |
| 17 | Hierarchical N-doped carbon nanocages/carbon textiles as a flexible O2 electrode for Li–O2 batteries显示文摘The conventional Li–O2 battery(LOB)has hardly been considered as a next-generation flexible electronics thus far,since it is bulk,inflexible and limited by the absence of an adjustable cell configuration.Here,we present a flexible Li–O2 cell using N-doped carbon nanocages grown onto the carbon textiles(NCNs/CTs)as a self-standing and binder-free O2 electrode.The highly flexible NCNs/CTs exhibits an excellent mechanic durability,a promising catalytic activity towards the ORR and OER,a considerable cyclability of more than 70 cycles with an overpotential of 0.36 V on the 1 stcycle at a constant current density of 0.2 m A/cm2,a good rate capability,a superior reversibility with formation and decomposition of desired Li2 O2,and a highly electrochemical stability even under stringent bending and twisting conditions.Our work represents a promising progress in the material development and architecture design of O2 electrode for flexible LOBs. | Jia Liu Dan Li Siqi Zhang Ying Wang Guiru Sun Zhao Wang Haiming Xie Liqun Sun | 2020 | Journal of Energy Chemistry2020，29，7： | 2 |

| 19 | CD49a^(+)CD49b^(+) NK cells induced by viral infection reflect an activated state of conventional NK cells显示文摘Natural killer(NK) cells are important innate effectors that play a pivotal role in the defense against tumors and infections and participate in regulating adaptive immunity. Recent studies have revealed phenotypic and functional heterogeneity of NK cells.Here, using murine models of acute and chronic lymphocytic choriomeningitis virus infection, we observed that a CD49a^(+)CD49b^(+) NK cell subset emerged in the liver and other tissues, and underwent vigorous expansion following viral infection,before progressively decreasing in cell number. These viral infection-induced CD49a^(+)CD49b^(+) NK cells displayed an activated and mature phenotype. Moreover, compared with liver-resident NK cells and conventional NK(cNK) cells, CD49a^(+)CD49b^(+) NK cells showed increased functional competence, as evidenced by higher amounts of IFN-γ production and stronger cytotoxic capabilities during viral infection. Generation of these CD49a^(+)CD49b^(+) NK cells was shown to be independent of the T-bet transcription factor. Adoptive transfer experiments revealed that c NK cells could convert into CD49a^(+)CD49b^(+) NK cells following viral infection. Collectively, these results suggest that viral infection-induced CD49a^(+)CD49b^(+) NK cells represent a transiently activated state of cNK cells. | Wenhan Li Jing Zhou Xianwei Wang Yuzhang Wu Lilin Ye Haiming Wei Rui Sun Zhigang Tian Hui Peng | 2020 | Science China(Life Sciences)2020，63，11： | 2 |
| 20 | Synthesis of an ordered porous carbon with the dual nitrogen-doped interfaces and its ORR catalysis performance显示文摘Both nitrogen-doping feature and pore structure are critical factors for developing nitrogen-doped carbons based catalysts with a high performance toward oxygen reduction reaction(ORR).Herein,a simple one-step CVD of acetylene and acetonitrile vapor method using silanized SBA-15 as a template has been developed to synthesize an ordered porous carbon(OPC) with dual nitrogen-doped interfaces.The optimized sample as prepared with the CVD of 4 h at 750℃ contains two types of ordered mesopores that one type is the ordered cylindrical pores inheriting from the pores of SBA-15 and has a pore width of4.0~5.0 nm,the other type is the ordered quasi-hexagonal pores with a width of 3.0~4.0 nm produced by etching the pore walls of SBA-15.These two types of pores whose pore walls are built by the nitrogen doped carbon layers resulted by the CVD and thus it actually makes the dual nitrogen-doped interfaced OPC(DN-OPC).Meanwhile,DN-OPC contains a few of micropores and a large SSA of 1430 m~2/g.This dualordered pores and dual nitrogen-doped interfaces cannot only facilitate mass transport but also utilize the active sites of DN-OPC for ORR.Therefore,as metal-free ORR catalyst,DN-OPC exhibits a good activity close to commercial Pt/C catalyst,and an excellent durability and methanol tolerance. | Hongwei Zhao Yanqiu Zhang Li Lixiang Xin Geng Haiming Yang Weimin Zhou Chengguo Sun Baigang An | 2021 | Chinese Chemical Letters2021，32，1： | 2 |
