| 1 | Raman Spectroscopy and Imaging of Graphene显示文摘Graphene has many unique properties that make it an ideal material for fundamental studies as well as for potential applications.Here we review recent results on the Raman spectroscopy and imaging of graphene.We show that Raman spectroscopy and imaging can be used as a quick and unambiguous method to determine the number of graphene layers.The strong Raman signal of single layer graphene compared to graphite is explained by an interference enhancement model.We have also studied the effect of substrates,the top layer deposition,the annealing process,as well as folding(stacking order)on the physical and electronic properties of graphene.Finally,Raman spectroscopy of epitaxial graphene grown on a SiC substrate is presented and strong compressive strain on epitaxial graphene is observed.The results presented here are highly relevant to the application of graphene in nano-electronic devices and help in developing a better understanding of the physical and electronic properties of graphene. | Zhenhua Ni Yingying Wang Ting Yu Zexiang Shen | 2008 | Nano Research2008，1，4： | 51 |
| 2 | Measurement and Interpretation of Connectivity of Chinese Cities in World City Network,2010显示文摘This is an empirical paper that measures and interprets the position of Chinese cities in the world city network in 2010. Building on a specification of the world city network as a′interlocking network′in which business services firms play the crucial role in city network formation, information is gathered about the presence of global service firms in cities. This information is converted into data to provide the′service value′of a city for a firm′s provision of corporate services in a 526(cities)×175(firms) matrix. These data are then used as the input to the interlocking network model in order to measure cities′connectivity and its predominant geographical orientation. Here we focus on the position of some key Chinese cities in this regard, and discuss and interpret results in the context of the urban dimensions of the′opening up′of the Chinese economy. | Ben DERUDDER Peter J TAYLOR Michael HOYLER NI Pengfei LIU Xingjian ZHAO Miaoxi SHEN Wei Frank WITLOX | 2013 | Chinese Geographical Science2013，23，3： | 40 |
| 3 | Anti-SARS-CoV-2 activities in vitro of Shuanghuanglian preparations and bioactive ingredients显示文摘Human infection with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)causes coronavirus disease 2019(COVID-19)and there is no cure currently.The 3CL protease(3CLpro)is a highly conserved protease which is indispensable for CoVs replication,and is a promising target for development of broad-spectrum antiviral drugs.In this study we investigated the anti-SARS-CoV-2 potential of Shuanghuanglian preparation,a Chinese traditional patent medicine with a long history for treating respiratory tract infection in China.We showed that either the oral liquid of Shuanghuanglian,the lyophilized powder of Shuanghuanglian for injection or their bioactive components dose-dependently inhibited SARS-CoV-23CLpro as well as the replication of SARS-CoV-2 in Vero E6 cells.Baicalin and baicalein,two ingredients of Shuanghuanglian,were characterized as the first noncovalent,nonpeptidomimetic inhibitors of SARS-CoV-23CLpro and exhibited potent antiviral activities in a cell-based system.Remarkably,the binding mode of baicalein with SARS-CoV-23CLpro determined by X-ray protein crystallography was distinctly different from those of known 3CLpro inhibitors.Baicalein was productively ensconced in the core of the substrate-binding pocket by interacting with two catalytic residues,the crucial S1/S2 subsites and the oxyanion loop,acting as a“shield”in front of the catalytic dyad to effectively prevent substrate access to the catalytic dyad within the active site.Overall,this study provides an example for exploring the in vitro potency of Chinese traditional patent medicines and effectively identifying bioactive ingredients toward a specific target,and gains evidence supporting the in vivo studies of Shuanghuanglian oral liquid as well as two natural products for COVID-19 treatment. | Hai-xia Su Sheng Yao Wen-feng Zhao Min-jun Li Jia Liu Wei-juan Shang Hang Xie Chang-qiang Ke Hang-chen Hu Mei-na Gao Kun-qian Yu Hong Liu Jing-shan Shen Wei Tang Lei-ke Zhang Geng-fu Xiao Li Ni Dao-wen Wang Jian-ping Zuo Hua-liang Jiang Fang Bai Yan Wu Yang Ye Ye-chun Xu | 2020 | Acta Pharmacologica Sinica2020，41，9： | 32 |

| 10 | A Strigolactone Biosynthesis Gene Contributed to the Green Revolution in Rice显示文摘Plant architecture is a complex agronomic trait and a major factor of crop yield,which is affected by several important hormones.Strigolactones(SLs)are identified as a new class hormoneinhibiting branching in many plant species and have been shown to be involved in various developmental processes.Genetical and chemical modulation of the SL pathway is recognized as a promising approach to modify plant architecture.However,whether and how the genes involved in the SL pathway could be utilized in breeding still remain elusive.Here,we demonstrate that a partial loss-of-function allele of the SL biosynthesis gene,HIGH TILLERING AND DWARF 1/DWARF17(HTD1/D17),which encodes CAROTENOID CLEAVAGE DIOXYGENASE 7(CCD7),increases tiller number and improves grain yield in rice.We found that the HTD1 gene had been widely utilized and co-selected with Semidwarf 1(SD1),both contributing to the improvement of plant architecture in modern rice varieties since the Green Revolution in the 1960s.Understanding how phytohormone pathway genes regulate plant architecture and how they have been utilized and selected in breeding will lay the foundation for developing the rational approaches toward improving crop yield. | Yuexing Wang Lianguang Shang Hong Yu Longjun Zeng Jiang Hu Shen Ni Yuchun Rao Sanfeng Li Jinfang Chu Xiangbing Meng Lei Wang Ping Hu Jijun Yan Shujing Kang Minghao Qu Hai Lin Tao Wang Quan Wang Xingming Hu Hongqi Chen Bing Wang Zhenyu Gao Longbiao Guo Dali Zeng Xudong Zhu Guosheng Xiong Jiayang Li Qian Qian | 2020 | Molecular Plant2020，13，6： | 23 |
| 11 | Dendritic Cells Transduced with SOCS1 Gene Exhibit Regulatory DC Properties and Prolong Allograft Survival显示文摘SOCS1 is a key regulator of cytokine signaling and is important for maintaining balance in the immune system. It is thought to participate in negative feedback loops in cytokine signaling and may be an important signal for the regulation of dendritic cell (DC) maturation. However, it remains unclear whether DCs transduced with SOCS1 exhibit characteristics of regulatory DCs and induce allogeneic T-cell hyporesponsiveness. In this study, we constructed adenoviral vector coding SOCS1 (Ad-SOCS1) that can efficiently increase SOCS1 gene expression in bone marrow-derived dendritic cells. DCs transduced with Ad-SOCS1 (DC-SOCS1) expressed low levels of costimulatory and MHC molecules, were resistant to maturation and activation stimulation, induced allogeneic T-cell hyporesponsiveness, and promoted the generation of regulatory-like T cells in vitro. DC-SOCS1 pretreatment significantly prolonged the survival of allografts and led to a substantial increase in the generation of regulatory T cells. Our data suggest that SOCS1 inhibits DC maturation and induces regulatory DC generation, therefore possessing therapeutic potential to prevent rejection in organ transplantation. | Hong Fu Shaohua Song Fang Liu Zhijia Ni Xiaoyun Shen Liang Xiao Guoshan Ding Quanxing Wang | 2009 | Cellular & Molecular Immunology2009，6，2： | 20 |

| 15 | Adaptive double chain quantum genetic algorithm for constrained optimization problems显示文摘Optimization problems are often highly constrained and evolutionary algorithms(EAs)are effective methods to tackle this kind of problems. To further improve search efficiency and convergence rate of EAs, this paper presents an adaptive double chain quantum genetic algorithm(ADCQGA) for solving constrained optimization problems. ADCQGA makes use of doubleindividuals to represent solutions that are classified as feasible and infeasible solutions. Fitness(or evaluation) functions are defined for both types of solutions. Based on the fitness function, three types of step evolution(SE) are defined and utilized for judging evolutionary individuals. An adaptive rotation is proposed and used to facilitate updating individuals in different solutions.To further improve the search capability and convergence rate, ADCQGA utilizes an adaptive evolution process(AEP), adaptive mutation and replacement techniques. ADCQGA was first tested on a widely used benchmark function to illustrate the relationship between initial parameter values and the convergence rate/search capability. Then the proposed ADCQGA is successfully applied to solve other twelve benchmark functions and five well-known constrained engineering design problems. Multi-aircraft cooperative target allocation problem is a typical constrained optimization problem and requires efficient methods to tackle. Finally, ADCQGA is successfully applied to solving the target allocation problem. | Kong Haipeng Li Ni Shen Yuzhong | 2015 | Chinese Journal of Aeronautics2015，28，1： | 13 |
| 16 | Estimation of the electromechanical characteristics of power systems based on a revised stochastic subspace method and the stabilization diagram显示文摘Estimating low-frequency oscillation modes and the corresponding mode shapes based on ambient data from WAMS measurements has a promising prospect in power system analysis and control.Based on the stochastic subspace method,this paper proposes a revised stochastic subspace method by introducing reference channels,which can estimate the modes and the mode shapes simultaneously with great computational efficiency.Meanwhile,the accuracy of the estimated results is not degraded.To discriminate the real modes from the spurious ones,the stabilization diagram is introduced.A novel algorithm is designed to deal with the stabilization diagram which can detect the real modes automatically.Tests conducted on the IEEE-118 system indicate that the proposed method has good performance in terms of both computational efficiency and accuracy,and has the potential of being used on-line. | NI JingMin SHEN Chen LIU Feng | 2012 | Science China(Technological Sciences)2012，55，6： | 12 |
| 17 | Pediatric reference intervals in China(PRINCE):design and rationale for a large,multicenter collaborative cross-sectional study显示文摘There is a lack of accurate pediatric reference intervals(RIs) in China, with most commonly used RIs established without consideration of the effect of age and gender. The Pediatric Reference Intervals in China(PRINCE) project aims to establish and verify pediatric RIs for 31 common laboratory measurands.The project will be a large, multicenter cross-sectional study:14,490 healthy children and adolescents aged up to 19 years will be surveyed by 10 children's hospitals and one pediatric department of a university hospital. To evaluate the feasibility and efficiency of the study methods, 602 children were surveyed in the pilot phase of the PRINCE study in April 2017: it found that some measurands were distinctly age dependent and that there were differences between values for males and females. The results of the pilot study affirmed the necessity of the PRINCE project for Chinese pediatrics. The pilot also indicated potential difficulties in the full survey, e.g., difficulties in recruiting children aged under 3 years and insufficient collection of blood samples from infants. The operation of the PRINCE project has been modified based on the findings in the pilot study toward improving the validity of the PRINCE project and promoting its openness and transparency. | Xin Ni Wenqi Song Xiaoxia Peng Ying Shen Yaguang Peng Qiliang Li Yan Wang Lixin Hu Yanying Cai Hong Shang Min Zhao Hong Jiang Yaoguo Huang Runqing Mu Wenxiang Chen Mingting Peng Chuanbao Zhang Jie Zeng Chenbin Li Hongling Yang Yongmei Jiang Jin Xu Guixia Li Hongbing Chen Yun Xiang Sancheng Cao Zhenxin Guo Dapeng Chen | 2018 | Science Bulletin2018，63，24： | 12 |
| 18 | Variable frequency of pulse hydraulic fracturing for improving permeability in coal seam显示文摘Variable frequency,a new pattern of pulse hydraulic fracturing,is presented for improving permeability in coal seam.A variable frequency pulse hydraulic fracturing testing system was built,the mould with triaxial loading was developed.Based on the monitor methods of pressure sensor and acoustic emission,the trials of two patterns of pulse hydraulic fracturing of single frequency and variable frequency were carried out,and at last fracturing mechanism was analyzed.The results show that the effect of variable frequency on fracture extension is better than that of single frequency based on the analysis of macroscopic figures and AE.And the shortage of single frequency is somewhat remedied when the frequency is variable.Under variable frequency,the pressure process can be divided into three stages:low frequency band,pressure stability band and high frequency band,and rupture pressure of the sample is smaller than that of the condition of single frequency.Based on the Miner fatigue theory,the effect of different loading sequences on sample rupture is discussed and the results show that it is better to select the sequence of low frequency at first and then high frequency.Our achievements can give a basis for the improvement and optimization of the pulse hydraulic fracturing technology. | Li Quangui Lin Baiquan Zhai Cheng Ni Guanhua Peng Shen Sun Chen Cheng Yanying | 2013 | International Journal of Mining Science and Technology2013，23，6： | 12 |
| 19 | Inflammatory biomarkers and cerebral small vessel disease:a community-based cohort study显示文摘Background and purpose Although inflammation has been proposed to be a candidate risk factor for cerebral small vessel disease(CSVD),previous findings remain largely inconclusive and vary according to disease status and study designs.The present study aimed to investigate possible associations between inflammatory biomarkers and MRI markers of CSVD.Methods A group of 15 serum inflammatory biomarkers representing a variety of those putatively involved in the inflammatory cascade was grouped and assessed in a cross-sectional study involving 960 stroke-free subjects.The biomarker panel was grouped as follows:systemic inflammation(high-sensitivity C reactive protein(hsCRP),interleukin 6 and tumour necrosis factorα),endothelial-related inflammation(E-selectin,P-selectin,intercellular adhesion molecule 1,vascular cell adhesion molecule 1(VCAM-1),CD40 ligand,lipoprotein-associated phospholipase A2,chitinase-3-like 1 protein and total homocysteine(tHCY))and media-related inflammation(matrix metalloproteinases 2,3 and 9,and osteopontin).The association(s)between different inflammatory groups and white matter hyperintensity(WMH),lacunes,cerebral microbleeds(CMBs),enlarged perivascular space(PVS)and the number of deep medullary veins(DMVs)were investigated.Results High levels of serum endothelial-related inflammatory biomarkers were associated with both increased WMH volume(R^(2)=0.435,p=0.015)and the presence of lacunes(R^(2)=0.254,p=0.027).Backward stepwise elimination of individual inflammatory biomarkers for endothelial-related biomarkers revealed that VCAM-1 was significant for WMH(β=0.063,p=0.005)and tHCY was significant for lacunes(β=0.069,p<0.001).There was no association between any group of inflammatory biomarkers and CMBs or PVS.Systemic inflammatory biomarkers were associated with fewer DMVs(R^(2)=0.032,p=0.006),and backward stepwise elimination of individual systemic-related inflammatory biomarkers revealed that hsCRP(β=−0.162,p=0.007)was significant.Conclusion WMH and lacunes were associated with endothelial-related inflammatory biomarkers,and fewer DMVs were associated with systemic inflammation,thus suggesting different underlying inflammatory processes and mechanisms. | Ding-Ding Zhang Yuan Cao Jing-Yu Mu Yi-Ming Liu Feng Gao Fei Han Fei-Fei Zhai Li-Xin Zhou Jun Ni Ming Yao Ming-Li Li Zheng-Yu Jin Shu-Yang Zhang Li-Ying Cui Yong Shen Yi-Cheng Zhu | 2022 | Stroke & Vascular Neurology2022，7，4： | 11 |
| 20 | LORELEI-LIKE GPI-ANCHORED PROTEINS 2/3 Regulate Pollen Tube Growth as Chaperones and Coreceptors for ANXUR/BUPS Receptor Kinases in Arabidopsis显示文摘Pollen tube growth is crucial for successful fertilization.In Arabidopsis thaliana,the ANXUR(ANX)/BUPS receptor kinase complex controls and maintains pollen tube growth in response to autocrine rapid alkalin-ization factor 4/19(RALF4/19)signaling;however,the molecular and cellular mechanisms underlying the ANX/BUPS-mediated regulation of pollen tube growth remain unclear.In this study,we found that pollen-specific LORELEI-like GPI-anchored proteins 2 and 3(LLG2/3)promote pollen tube growth in vitro and in vivo.LLG2/3 interacte with ANX/BUPS in a RALF4-concentration-dependent manner,suggesting that ANX/BUPS and LLG2/3 might form a receptor-coreceptor complex for perceiving RALF peptide signals.Disruption of the ANX/BUPS-LLG2/3 interaction led to the cytoplasmic retention of ANX1/2,in either llg2/3 knockdown mutants or in anx1/2 mutants lacking the J region,which mediates the ANX/BUPS-LLG2/3 interaction.Moreover,we found that RALF4 induced the production of reactive oxygen species(ROS),which stimulate pollen tube growth and reduce pollen burst rate.ROS levels are reduced in the pollen tubes of LLG2/3 RNAi lines,and application of exogenous H2O2 could partially rescue the defective pollen tube growth of LLG2/3 RNAi lines.Taken together,our study identifies LLG2/3 as novel regulatory components of pollen tube growth,and shows that they chaperone ANX/BUPS for secretion to the apical plasma membrane of pollen tube and act as coreceptors of ANX/BUPS in the acti-vation of ROS production for promoting pollen tube growth. | Hanqian Feng Chen Liu Rong Fu Minmin Zhang Hui Li Lianping Shen Qiqi Wei Xiang Sun Lin Xu Bin Ni Chao Li | 2019 | Molecular Plant2019，12，12： | 10 |
