| 1 | An isoflavone derivative potently inhibits the angiogenesis and progression of triple-negative breast cancer by targeting the MTA2/SerRS/VEGFA pathway显示文摘Objective:Angiogenesis plays a vital role in tumor growth and metastasis.Here,we aimed to find novel efficient antiangiogenic molecules targeting vascular endothelial growth factor A(VEGFA)at the transcriptional level to treat triple-negative breast cancer(TNBC).Methods:We used a cell-based seryl tRNA synthetase(SerRS)promoter-driven dual-luciferase reporter system to screen an in-house library of 384 naturally occurring small molecules and their derivatives to find candidate molecules that could upregulate the expression of SerRS,a potent transcriptional repressor of VEGFA.The levels of SerRS and VEGFA were examined by quantitative RT-PCR(qRT-PCR),western blotting,and/or ELISAs in TNBC cells after candidate molecule administration.Zebrafish,the Matrigel plug angiogenesis assay in mice,the TNBC allograft,and xenograft mouse models were used to evaluate thein vivoanti-angiogenic and anti-cancer activities.Furthermore,the potential direct targets of the candidates were identified by proteomics and biochemical studies.Results:We found the most active compound was 3-(4-methoxyphenyl)quinolin-4(1H)-one(MEQ),an isoflavone derivative.In TNBC cells,MEQ treatment resulted in increased SerRS mRNA(P<0.001)and protein levels and downregulated VEGFA production.Both the vascular development of zebrafish and Matrigel plug angiogenesis in mice were inhibited by MEQ.MEQ also suppressed the angiogenesis in TNBC allografts and xenografts in mice,resulting in inhibited tumor growth and prolonged overall survival(P<0.05).Finally,we found that MEQ regulated SerRS transcription by interacting with MTA2(Metastasis Associated 1 Family Member 2).Conclusions:Our findings suggested that the MTA2/SerRS/VEGFA axis is a drug-treatable anti-angiogenic target,and MEQ is a promising anti-tumor molecule that merits further investigation for clinical applications. | Xiaotong Zhang Gengyi Zou Xiyang Li Lun Wang Tianyu Xie Jin Zhao Longlong Wang Shunchang Jiao Rong Xiang Haoyu Ye Yi Shi | 2020 | Cancer Biology & Medicine2020，17，3： | 6 |
| 2 | A novel glasses-free virtual reality rehabilitation system on improving upper limb motor function among patients with stroke:A feasibility pilot study显示文摘Background:Virtual reality(VR)technology is increasingly used in stroke rehabilitation.This study aimed to investigate the effectiveness of using the glasses-free VR training to improve motor function of upper limb in patients with stroke.Methods:Twelve patients with stroke were recruited to participate in the intervention of 3 weeks.At the baseline and post intervention,two times of evaluation including Fugl-Meyer upper-extremity scale(FMS-UE),transcranial magnetic stimulation(TMS)measurement and motion evaluation were performed.Results:No significant difference was observed between two groups at baseline evaluation.After the intervention,the FMS-UE scores presented a greater improvement in the VR group compared with the control group.TMS measurement showed that there was significant difference in cortex latency and central motor conduction time between two groups after the intervention,but no significant difference in the amplitude of motor event potential was observed.In addition,there was a significant correlation between game scores and FMS-UE scores.Conclusions:The novel glasses-free VR training was at least as effective as conventional occupational therapy in upper limb motor function,improving nerve conduction time and corticospinal excitability in patient with stroke. | Haoyu Xie Hantao Zhang Haowen Liang Hang Fan Jianying Zhou Wai Leung Ambrose Lo Le Li | 2021 | Medicine in Novel Technology and Devices2021，，3： | 2 |
| 3 | A metal-electrode-free, fully integrated, soft triboelectric sensor array for self-powered tactile sensing显示文摘The dramatic advances in flexible/wearable electronics have garnered great attention for touch sensors for practical applications in human health monitoring and human–machine interfaces.Self-powered triboelectric tactile sensors with high sensitivity,reduced crosstalk,and simple processing routes are highly desirable.Herein,we introduce a facile and low-cost fabrication approach for a metal-electrode free,fully integrated,flexible,and self-powered triboelectric tactile sensor array with 8-by-8 sensor units.Through the height difference between the sensor units and interconnect electrodes,the crosstalk derived from the electrodes has been successfully suppressed with no additional shielding layers.The tactile sensor array shows a remarkable sensitivity of 0.063VkPa^(–1) with a linear range from 5 to 50kPa,which covers a broad range of testing objects.Furthermore,due to the advanced mechanical design,the flexible sensor array exhibits great capability of pressure sensing even under a curved state.The voltage responses from the pattern mapping by finger touching demonstrate the uniformity of the sensor array.Finally,real-time tactile sensing associated with light-emitting diode(LED)array lighting demonstrates the potential application of the sensor array in position tracking,self-powered touch screens,human–machine interfaces and many others. | Lingyun Wang Yiming Liu Qing Liu Yuyan Zhu Haoyu Wang Zhaoqian Xie Xinge Yu Yunlong Zi | 2020 | Microsystems & Nanoengineering2020，6，1： | 2 |
| 4 | Ciphertext-Only Attacks Against Compact-LWE Submitted to NIST PQC Project显示文摘As a candidate of the standard of post-quantum cryptography for NIST,Liu,et al.submitted a new public-key encryption scheme Compact-LWE,whose structure is similar to LWE,but with different distribution of errors.They thought that the special error distribution would protect Compact-LWE from known lattice-based attacks.Furthermore,they recommended a set of small parameters to improve the efficiency of Compact-LWE and claimed it can offer 192-bit security.However,in this paper,the authors show that Compact-LWE is not secure under recommended parameters by presenting two ciphertext-only attacks.First,the authors show that the message can be recovered efficiently from the ciphertext.Then the authors go further to recover an equivalent private key efficiently from the public key by exploiting the special structure of Compact-LWE. | LI Haoyu LIU Renzhang LIU Zhen PAN Yanbin XIE Tianyuan | 2022 | Journal of Systems Science & Complexity2022，35，3： | 2 |
| 5 | Seismic damage to structures in the Ms6.5 Ludian earthquake显示文摘On 3 August 2014,the Ludian earthquake struck northwest Yunnan Province with a surface wave magnitude of 6.5.This moderate earthquake unexpectedly caused high fatalities and great economic loss.Four strong motion stations were located in the areas with intensity V,VI,VII and IX,near the epicentre.The characteristics of the ground motion are discussed herein,including 1)ground motion was strong at a period of less than 1.4 s,which covered the natural vibration period of a large number of structures;and 2)the release energy was concentrated geographically.Based on materials collected during emergency building inspections,the damage patterns of adobe,masonry,timber frame and reinforced concrete(RC)frame structures in areas with different intensities are summarised.Earthquake damage matrices of local buildings are also given for fragility evaluation and earthquake damage prediction.It is found that the collapse ratios of RC frame and confined masonry structures based on the new design code are significantly lower than non-seismic buildings.However,the RC frame structures still failed to achieve the ‘strong column,weak beam' design target.Traditional timber frame structures with a light infill wall showed good aseismic performance. | Chen Hao Xie Quancai Dai Boyang Zhang Haoyu Chen Hongfu | 2016 | Earthquake Engineering and Engineering Vibration2016，15，1： | 2 |

| 9 | Parallel design of convolutional neural networks for remote sensing images object recognition based on data-driven array processor显示文摘Object recognition in very high-resolution remote sensing images is a basic problem in the field of aerial and satellite image analysis.With the development of sensor technology and aerospace remote sensing technology,the quality and quantity of remote sensing images are improved.Traditional recognition methods have a certain limitation in describing higher-level features,but object recognition method based on convolutional neural network(CNN)can not only deal with large scale images,but also train features automatically with high efficiency.It is mainly used on object recognition for remote sensing images.In this paper,an AlexNet CNN model is trained using 2100 remote sensing images,and correction rate can reach 97.6%after 2000 iterations.Then based on trained model,a parallel design of CNN for remote sensing images object recognition based on data-driven array processor(DDAP)is proposed.The consuming cycles are counted.Simultaneously,the proposed architecture is realized on Xilinx V6 development board,and synthesized based on SMIC 130 nm complementary metal oxid semiconductor(CMOS)technology.The experimental results show that the proposed architecture has a certain degree of parallelism to achieve the purpose of accelerating calculations. | Shan Rui Jiang Lin Deng Junyong Cui Pengfei Zhang Yuting Wu Haoyue Xie Xiaoyan | 2020 | The Journal of China Universities of Posts and Telecommunications2020，27，6： | 1 |

| 11 | Aligned Organization of Synapses and Mitochondria in Auditory Hair Cells显示文摘Recent studies have revealed great functional and structural heterogeneity in the ribbon-type synapses at the basolateral pole of the isopotential inner hair cell(IHC).This feature is believed to be critical for audition over a wide dynamic range,but whether the spatial gradient of ribbon morphology is fine-tuned in each IHC and how the mitochondrial network is organized to meet local energy demands of synaptic transmission remain unclear.By means of three-dimensional electron microscopy and artificial intelligence-based algorithms,we demonstrated the cell-wide structural quantification of ribbons and mitochondria in mature mid-cochlear IHCs of mice.We found that adjacent IHCs in staggered pairs differ substantially in cell body shape and ribbon morphology gradient as well as mitochondrial organization.Moreover,our analysis argues for a location-specific arrangement of correlated ribbon and mitochondrial function at the basolateral IHC pole. | Jing Liu Shengxiong Wang Yan Lu Haoyu Wang Fangfang Wang Miaoxin Qiu Qiwei Xie Hua Han Yunfeng Hua | 2022 | Neuroscience Bulletin2022，38，3： | 1 |
| 12 | Research on thermal risk and decomposition behavior of methyl nitrite显示文摘The thermal hazards of methyl nitrite(MN)were investigated in the present study.The determination and evaluation of MN decomposition were conducted using a C600 micro thermometer.The thermal runaway reaction characteristics of the compound under different initial pressures were obtained using a VSP2 calorimeter.The kinetic parameters of MN were obtained by regression fitting and calculation of the microthermal experimental data.The experimental and calculated results demonstrated that the potential explosion risk of MN is very high.In addition,there was a high energy barrier in the early stage of the uncontrolled decomposition of MN;however,once the decomposition reaction was initiated,the subsequent decomposition was easily conducted.Under the conditions of adiabatic simulation,the possibility that the reaction was uncontrolled increases with the initial temperature and pressure of the system,and there is a great potential safety risk. | Haoyu Zhai Shaomeng Wang Diankun Chen Xuanying Cheng Chuanxin Xie | 2020 | Chinese Journal of Chemical Engineering2020，28，8： | 1 |

| 14 | System level test selection based on combinatorial dependency matrix显示文摘Test selection is to select the test set with the least total cost or the least total number from the alternative test set on the premise of meeting the required testability indicators.The existing models and methods are not suitable for system level test selection.The first problem is the lack of detailed data of the units’fault set and the test set,which makes it impossible to establish a traditional dependency matrix for the system level.The second problem is that the system level fault detection rate and the fault isolation rate(referred to as'two rates')are not enough to describe the fault diagnostic ability of the system level tests.An innovative dependency matrix(called combinatorial dependency matrix)composed of three submatrices is presented.The first problem is solved by simplifying the submatrix between the units’fault and the test,and the second problem is solved by establishing the system level fault detection rate,the fault isolation rate and the integrated fault detection rate(referred to as'three rates')based on the new matrix.The mathematical model of the system level test selection problem is constructed,and the binary genetic algorithm is applied to solve the problem,which achieves the goal of system level test selection. | YANG Peng XIE Haoyu QIU Jing | 2021 | Journal of Systems Engineering and Electronics2021，32，4： | 0 |
| 15 | Application of biocompatible custom ceria nanoparticles in improving the quality of liver grafts for transplantation显示文摘Liver transplantation(LT),an ultimate and vital method for treating end-stage liver disease,is often accompanied by ischemiareperfusion injury(IRI)resulting from warm or cold ischemia of the donor liver.Organ protection techniques are used to improve the quality of liver grafts(from retrieval to implantation).Reactive oxygen species(ROS)cause oxidative stress,which is considered a crucial factor in IRI after LT.Nano antioxidants capable of scavenging ROS alleviate IRI in multiple types of organs and tissues.In this study,we synthesized ceria nanoparticles(NPs)with antioxidant properties using a pyrolysis method and covered them with phospholipid-polyethylene glycol to improve their biocompatibility in vivo.We investigated the potential organprotective effect of ceria NPs and the underlying mechanisms.Ceria NPs promoted liver function recovery after LT by attenuating IRI in liver grafts in vivo.The protective effect of ceria NPs on liver grafts was investigated by applying hypothermic oxygenated machine perfusion ex vivo.Ceria NPs attenuated hypoxia reoxygenation-or H_(2)O_(2)-induced hepatocyte injury by enhancing mitochondrial activity and ROS scavenging in vitro.These effects may be associated with the activation of the nuclear factor erythroid-derived 2-related factor 2(Nrf2)/Kelch-like ECH-associated protein 1(Keap1)/heme oxygenase 1(HO-1)signaling pathway.In conclusion,ceria NPs may serve as a promising antioxidant agent for the treatment of hepatic IRI after LT. | Yinbiao Qiao Jianhui Li Suchen Bian Chenyue Zhan Jia Luo Li Jiang Haoyu Li Hao Wu Cheng Zhang Shusen Zheng Haiyang Xie Penghong Song | 2023 | Nano Research2023，16，4： | 0 |
| 16 | Antimicrobial resistance characteristics and phylogenetic relationships of pleuromutilin-resistant Enterococcus isolates from different environmental samples along a laying hen production chain显示文摘Antimicrobial resistance in the laying hen production industry has become a serious public health problem.The antimicrobial resistance and phylogenetic relationships of the common conditional pathogen Enterococcus along the laying hen production chain have not been systematically clarified.105 Enterococcus isolates were obtained from 115 environmental samples (air,dust,feces,fies,sewage,and soil) collected along the laying hen production chain (breeding chicken,chick,young chicken,and commercial laying hen).These Enterococcus isolates exhibited resistance to some clinically relevant antibiotics,such as tetracycline (92.4%),streptomycin (92.4%),and erythromycin (91.4%),and all strains had multidrug resistance phenotypes.Whole genome sequencing characterized 29 acquired antibiotic resistance genes (ARGs) that conferred resistance to 11 classes of antibiotics in 51pleuromutilin-resistant Enterococcus isolates,and lsa(E),which mediates resistance to pleuromutilins,always co-occurred with lnu(B).Alignments with the Mobile Genetic Elements database identified four transposons (Tn554,Tn558,Tn6261,and Tn6674) with several ARGs(erm(A),ant(9)-la,fex(A),and optrA) that mediated resistance to many clinically important antibiotics.Moreover,we identified two new transposons that carried ARGs in the Tn554 family designated as Tn7508 and Tn7492.A complementary approach based on conventional multi-locus sequence typing and whole genome single nucleotide polymorphism analysis showed that phylogenetically related pleuromutilin-resistant Enterococcus isolates were widely distributed in various environments on different production farms.Our results indicate that environmental contamination by antimicrobial-resistant Enterococcus requires greater attention,and they highlight the risk of pleuromutilin-resistant Enterococcus and ARGs disseminating along the laying hen production chain,thereby warranting effective disinfection. | Cong Lin Yuxuan Feng Xianjun Xie Haoyu Zhang Jie Wu Yixiao Zhu Jing Yu Jingyi Feng Wen Su Shanming Lai Anyun Zhang | 2024 | Journal of Environmental Sciences2024，，3： | 0 |
| 17 | Dual-Driven Hemostats Featured with Puncturing Erythrocytes for Severe Bleeding in Complex Wounds显示文摘Achieving rapid hemostasis in complex and deep wounds with secluded hemorrhagic sites is still a challenge because of the difficulty in delivering hemostats to these sites.In this study,a Janus particle,SEC-Fe@CaT with dual-driven forces,bubble-driving,and magnetic field–(MF–)mediated driving,was prepared via in situ loading of Fe_(3)O_(4) on a sunflower sporopollenin exine capsule(SEC),and followed by growth of flower-shaped CaCO3 clusters.The bubble-driving forces enabled SEC-Fe@CaT to self-diffuse in the blood to eliminate agglomeration,and the MF-mediated driving force facilitated the SEC-Fe@CaT countercurrent against blood to access deep bleeding sites in the wounds.During the movement in blood flow,the meteor hammer-like SEC from SEC-Fe@CaT can puncture red blood cells(RBCs)to release procoagulants,thus promoting activation of platelet and rapid hemostasis.Animal tests suggested that SEC-Fe@CaT stopped bleeding in as short as 30 and 45 s in femoral artery and liver hemorrhage models,respectively.In contrast,the similar commercial product Celox™required approximately 70 s to stop the bleeding in both bleeding modes.This study demonstrates a new hemostat platform for rapid hemostasis in deep and complex wounds.It was the first attempt integrating geometric structure of sunflower pollen with dual-driven movement in hemostasis. | Haoyu Qiu Guangqian Lan Weiwei Ding Xinyu Wang Wenyi Wang Dahua Shou Fei Lu Enling Hu Kun Yu Songmin Shang Ruiqi Xie | 2022 | Research2022，，4： | 0 |
| 18 | Carbon dots:An innovative luminescent nanomaterial显示文摘In recent years,carbon dots(CDs),including carbon nanodots,carbonized polymer dots,carbon quantum dots,and graphene quantum dots have attracted a mounting interest as readily accessible,nontoxic,and relatively inexpensive carbon-based nanomaterials.Yet,despite intense research for a number of years,a unifying picture is still lacking to clarify the exact definition,clear chemical structure,and unique optical properties of this family of nanomaterials.In this review,we systematically summarize the recent development of CDs from molecular design to related properties of excited states as well as their applications in optoelectronic devices and biology.We point out the current challenges,including exploring precise synthesis,clarifying the structure-property relationship,and regulating singlet and triplet states of fluorescence,phosphorescence,and delayed fluorescence.Moreover,the structural optimization of optoelectronic devices,tumor targeting mechanism,selective imaging,and drug delivery of CDs are also highlighted.We hope that the information provided in this review will inspire more exciting research on CDs from a brand-new perspective and promote practical application of CDs in multiple directions of current and future research. | Yuxin Shi Huimin Xu Ting Yuan Ting Meng Hao Wu Jianqiao Chang Haoyu Wang Xianzhi Song Yunchao Li Xiaohong Li Yang Zhang Wenjing Xie Louzhen Fan | 2022 | Aggregate2022，3，3： | 0 |
| 19 | Waste-to-wealth:Functional biomass carbon dots based on bee pollen waste and application显示文摘Waste utilization is not only the protection of the environment and the practice of green chemistry,but also one of the ways to develop new materials.Herein,we report two biomass carbon dots which prepared from bee pollen waste by one-step hydrothermal method.The new two carbon dots were used in sensing,cell imaging and plant growth regulation.The differences in the structure and properties of the two carbon dots were evaluated by TEM,XPS,TG and various spectroscopic methods.Both two carbon dots contain abundant functional groups,polyatomic doping,excellent water solubility and stable photoluminescence.Due to these good properties,we have demonstrated its versatile applications in Fe3+sensing,cell imaging and plant growth regulation.It shows sensitive and specific Fe^(3+) responsiveness and good biocompatibility.This research provides a green and simple method for the recycling and reuse of bee pollen waste,and also provides a reference for the application of biomass carbon dots. | Feishi Shan Lijuan Fu Xiangyu Chen Xiangyan Xie Chengshuang Liao Yinxia Zhu Haoyu Xia Jing Zhang Li Yan Zhouyu Wang Xiaoqi Yu | 2022 | Chinese Chemical Letters2022，33，6： | 0 |
| 20 | Preliminary Study on Water Demand Law of 1-0 Rooted Cuttings of Populus szechuanica显示文摘In order to provide theoretical basis and technical support for the afforestation and artificial water supply of P.szechuanica in arid areas,the characteristics of water consumption of P.szechuanica were explored,and the law of water demand of P.szechuanica was grasped.In this paper,potted seedlings of 1-0 rooted cuttings of P.szechuanica were taken as research objects,and change situation of water consumption under different water control gradients was measured regularly by using weighing method,further analyzing dynamic change of water consumption of P.szechuanica and revealing water demand law of 1-0 rooted cuttings of P.szechuanica.The results showed that total change of water consumption of 1-0 rooted cuttings of P.szechuanica had'slow-fast-slow-fast'double-peak trend in the growth period of the current year,and corresponded with univariate linear relation(R^(2)=0.7137),with significant difference.In whole growth period,water consumption in August was the highest,which was 2.7 times of that in June and July and 1.5 times of that after September.In different water control treatments,the dynamic changes of daily and monthly water consumption were significantly different.In seven water control treatments,monthly water consumption was between(6315.95±1690.70)and(10105.28±3065.30)g/month,and mean was(8211.07±2308.23)g/month.With intensification of water control treatment,water consumption increased,but there was no seedling death due to water shortage.P.szechuanica has great plasticity in water demand,and can survive in both arid and humid environments.Meanwhile,it is revealed that P.szechuanica is the most widely distributed tree species in the region. | Dabuqiong Haoyu WANG Huanhuan XIE Zhen XING Yanhui YE | 2021 | Meteorological and Environmental Research2021，12，4： | 0 |
