| 2 | Effect of oxymatrine on the replication cycle of hepatitis B virus in vitro显示文摘AIM:To determine the antiviral mechanism or target of oxymatrine against hepatitis B virus(HBV).METHODS:HepG2.2.15 cells were incubated with culture medium containing 500 μg/mL of oxymatrine for 2 and 5 d.The surface antigen of HBV(HBsAg) and e antigen of HBV(HBeAg) in supernatant were determined by ELISA.HBV DNA in supernatant,and intracellular covalently closed circular DNA(cccDNA),relaxed circular DNA(rcDNA) and pregenomic RNA(pgRNA) were quantif ied by specif ic real-time polymerase chain reaction(PCR) or reverse transcription(RT)-PCR.RESULTS:Treatment with oxymatrine for 2 d and 5 d reduced the production of HBV by the cell line,as indicated by the decline of HBsAg(22.67%,t = 5.439,P = 0.0322 and 22.39%,t = 5.376,P = 0.0329,respectively),HBeAg(55.34%,t = 9.859,P = 0.0101 and 43.97%,t = 14.080,P = 0.0050) and HBV DNA(40.75%,t = 4.570,P = 0.0447 and 75.32%,t = 14.460,P = 0.0047) in the supernatant.Intracellular cccDNA was also markedly reduced by 63.98%(t = 6.152,P = 0.0254) and 80.83%(t = 10.270,P = 0.0093),and intracellular rcDNA by 34.35%(t = 4.776,P = 0.0413) and 39.24%(t = 10.050,P = 0.0097).In contrast,intracellular pgRNA increased by 6.90-fold(t = 8.941,P = 0.0123) and 3.18-fold(t = 7.432,P = 0.0176) after 500 μg/mL of oxymatrine treatment for 2 d and 5 d,respectively.CONCLUSION:Oxymatrine may inhibit the replication of HBV by interfering with the process of packaging pgRNA into the nucleocapsid,or inhibiting the activity of the viral DNA polymerase. | Xu, Wen-Sheng Zhao, Ke-Kai Miao, Xiao-Hui Ni, Wu Cai, Xiong Zhang, Rui-Qi Wang, Jun-Xue | 2010 | World Journal of Gastroenterology2010，16，16： | 27 |
| 3 | Progresses on microwave remote sensing of land surface parameters显示文摘Highly accurate observations at various scales on the land surface are urgently needed for the studies of many areas,such as hydrology,meteorology,and agriculture.With the rapid development of remote sensing techniques,remote sensing has had the capacity of monitoring many factors of the Earth's land surface.Especially,the space-borne microwave remote sensing systems have been widely used in the quantitative monitoring of global snow,soil moisture,and vegetation parameters with their all-weather,all-time observation capabilities and their sensitivities to the characteristics of land surface factors.Based on the electromagnetic theories and microwave radiative transfer equations,researchers have achieved great successes in the microwave remote sensing studies for different sensors in recent years.This article has systematically reviewed the progresses on five research areas including microwave theoretical modeling,microwave inversion on soil moisture,snow,vegetation and land surface temperatures.Through the further enrichment of remote sensing datasets and the development of remote sensing theories and inversion techniques,remote sensing including microwave remote sensing will play a more important role in the studies and applications of the Earth systems. | SHI JianCheng DU Yang DU JinYang JIANG LingMei CHAI LinNa MAO KeBiao XU Peng NI WenJian XIONG Chuan LIU Qiang LIU ChenZhou GUO Peng CUI Qian LI YunQing CHEN Jing WANG AnQi LUO HeJia WANG YinHui | 2012 | Science China Earth Sciences2012，55，7： | 24 |
| 4 | 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 |

| 6 | Changes of the proportion and mortality of pulmonary thromboembolism in hospitalized patients from 1974 to 2005显示文摘Background Pulmonary thromboembolism (PTE) has become a common disease that severely endangers people’s health. This study analysed the changes in proportion and mortality of PTE in hospitalized patients to provide data for prevention and management of the disease. Methods The data of 763 hospitalized patients with PTE from 1974 to 2005 in Fuwai Hospital were analysed. Results During the 1970s, 0.27% of patients in a cardiovascular hospital had PTE (< 5 cases per year); while so far this century the proportion is 0.94% (48 to 113 per year). The mortality of hospitalized PTE patients fell from 20.00% in the 1970s to 4.10% this century. Prior to 1990, the mortality of hospitalized PTE patients was 12.50%, and in the years after 1990 only 3.40%. The difference was statistically significant (P<0.005). People with this disease were mostly between the ages of 30 and 69 years. Men were most susceptible between the ages of 30 and 69 years, while women between the ages of 40 and 69 years. Men contracted PTE 10 years earlier than women. The mortality of male PTE patients was 4.70%, not significantly different from female patients, 5.06% (0.500.1). More people contracted the disease in winter than in other seasons (P<0.05). There was no obvious difference between the mortality in different seasons overall (0.75 | TAN Xiao-yan HE Jian-guo ZOU Zhi-peng ZHAO Yan-fen CHEN Bai-ping GAO Ying XIONG Chang-ming NI Xin-hai CHENG Xian-sheng | 2006 | Chinese Medical Journal2006，，12： | 16 |
| 7 | A Potential Disease Susceptibility Gene CsLOB of Citrus Is Targeted by a Major Virulence Effector PthA of Xanthomonas citri subsp, citri显示文摘Dear Editor, Citrus bacterial canker (CBC),one of the most destructive diseases of citrus,has a severe economic impact on citrus industries in tropical and subtropical countries (Das,2003).It has been widely known that Xanthomonas cirri subsp.cirri (Xcc) causes the CBC by transferring the type-Ⅲ effectors (T3SEs) to the interior of the plant cell through type-Ⅲ secretion system (T3S) to modulate transcription of host plants to trigger CBC disease (Schaad et al.,2006).Pathotype A,the Asiatic form of Xcc,has a wide host range,is pathogenic on almost all citrus varieties,and contains a major virulence gene pthA encoding a T3S-secreted transcriptional activator-like effector (TALE) that promotes cellular hypertrophy (Al-Saadi et al.,2007).However,the susceptibility gene in citrus being responsible for the CBC and matching PthA of Xcc is largely unknown. | Zheng Li Lifang Zou Gang Ye Li Xiong Zhiyuan Ji Muhammad Zakria Ni Hong Guoping Wang Gongyou Chen | 2014 | Molecular Plant2014，7，5： | 9 |
| 8 | Dual-comb spectroscopy resolved three-degreeof-freedom sensing显示文摘Precise and fast determination of position and orientation, which is normally achieved by distance and angle measurements, has broad applications in academia and industry. We propose a dynamic three-degree-of-freedom measurement technique based on dual-comb interferometry and a self-designed grating-corner-cube(GCC) combined sensor. Benefiting from its unique combination of diffraction and reflection characteristics, the absolute distance, pitch, and yaw of the GCC sensor can be determined simultaneously by resolving the phase spectra of the corresponding diffracted beams. We experimentally demonstrate that the method exhibits a ranging precision(Allan deviation) of 13.7 nm and an angular precision of 0.088 arcsec, alongside a 1 ms reaction time. The proposed technique is capable of precise and fast measurement of distances and two-dimensional angles over long stand-off distances. A system with such an overall performance may be potentially applied to space missions,including in tight formation-flying satellites, for spacecraft rendezvous and docking, and for antenna measurement as well as the precise manufacture of components including lithography machines and aircraftmanufacturing devices. | SIYU ZHOU VUNAM LE SHILIN XIONG YUETANG YANG KAI NI QIAN ZHOU GUANHAO WU | 2021 | Photonics Research2021，9，2： | 8 |
| 9 | Combined effects of cadmium and fluoranthene on germination, growth and photosynthesis of soybean seedlings显示文摘The single and combinational effects of cadmium (Cd) and fluoranthene (FLT) on germination, growth and photosynthesis of soybean seedlings were investigated. Exposure to 5, 10, or 15 mg Cd/L or 1, 5, or 10 mg FLT/L individually or in combination significantly decreased germination vigor (3 days) and final germination rate of soybean seeds, except at 1 and 5 mg FLT/L. The results of two-way ANOVA analysis and the Bliss independence model showed that at lower concentrations of FLT (1 mg/L), the interaction between Cd and FLT on germination was antagonistic, whereas the interaction was synergistic when the concentration of FLT was 5 or 10 mg/L and the concentration of Cd was 15 mg/L. Growth, expressed as dry weight, length of shoot and root, leaf area, and photosynthesis, expressed as net photosynthetic rate, intercellular CO2 concentration, chlorophyll contents and fluorescence of soybean seedlings were also reduced by exposure to 5 or 10 mg Cd/L or 1 or 5 mg FLT/L, singly or jointly. Significant antagonistic effects of exposure to 5 or 10 mg Cd/L or 1 or 5 mg FLT/L on shoot growth and photosynthesis were observed, whereas synergy and antagonism of Cd and FLT were both observed for root growth. | Qiushuang Li Yonglong Lu Yajuan Shi Tieyu Wang Kun Ni Li Xu Shijie Liu Lin Wang Qinli Xiong John.P Giesy | 2013 | Journal of Environmental Sciences2013，25，9： | 8 |
| 10 | TDOA Localization Algorithm with Compensation of Clock Offset for Wireless Sensor Networks显示文摘This paper presents a source localization algorithm based on the source signal's time-difference-of-arrival(TDOA) for asynchronous wireless sensor network.To obtain synchronization among anchors,all anchors broadcast signals periodically,the clock offsets and skews of anchor pairs can be estimated using broadcasting signal's time-of-arrivals(TOA) at anchors.A kalman filter is adopted to improve the accuracy of clock offsets and track the clock drifts due to random fluctuations.Once the source transmits signal,the TOAs at anchors are stamped respectively and source's TDOA error due to clock offset and skew of anchor pair can be mitigated by a compensation operation.Based on a Gaussian noise model,maximum likelihood estimation(MLE) for the source position is obtained.Performance issues are addressed by evaluating the Cramer-Rao lower bound and the selection of broadcasting period.The proposed algorithm is simple and effective,which has close performance with synchronous TDOA algorithm. | XIONG Hui CHEN Zhiyuan YANG Beiya NI Rongpei | 2015 | China Communications2015，12，10： | 8 |

| 12 | Analysis of a Vortex Precipitation Event over Southwest China Using AIRS and In Situ Measurements显示文摘A strong precipitation event caused by the southwest vortex(SWV), which affected Sichuan Province and Chongqing municipality in Southwest China on 10–14 July 2012, is investigated. The SWV is examined using satellite observations from AIRS(Atmospheric Infrared Sounder), in situ measurements from the SWV intensive observation campaign, and MICAPS(Marine Interactive Computer-Aided Provisioning System) data. Analysis of this precipitation process revealed that:(1)heavy rain occurred during the development phase, and cloud water content increased significantly after the dissipation of the SWV;(2) the area with low outgoing longwave radiation values from AIRS correlated well with the SWV;(3) variation of the temperature of brightness blackbody(TBB) from AIRS reflected the evolution of the SWV, and the values of TBB reduced significantly during the SWV's development; and(4) strong temperature and water vapor inversions were noted during the development of the SWV. The moisture profile displayed large vertical variation during the SWV's puissant phase,with the moisture inversion occurring at low levels. The moisture content during the receding phase was significantly reduced compared with that during the developing and puissant phases. The vertical flux of vapor divergence explained the variation of the moisture profile. These results also indicate the potential for using AIRS products in studying severe weather over the Tibetan Plateau and its surroundings, where in situ measurements are sparse. | Chengcheng NI Guoping LI Xiaozhen XIONG | 2017 | Advances in Atmospheric Sciences2017，34，4： | 7 |
| 13 | Flexible N-Doped reduced graphene oxide/carbon Nanotube-MnO_(2) film as a Multifunctional Material for High-Performance supercapacitors, catalysts and sensors显示文摘A flexible 3D N-doped reduced graphene oxide(N-RGO)/carbon nanotube(CNT)eMnO_(2) hybrid film was constructed with outstanding supercapacitor,excellent oxygen reduction reaction(ORR)and good sensing performances.The resultant hybrid film possessed large specific capacitances of 418 F g^(-1) and 209 mF cm^(-2) in aqueous and solid electrolytes,and outstanding capacitance retentions of 95% and 94% were obtained for both electrolytes after experiencing 5000 cycles.A simple supercapacitor based on the resultant flexible hybrid film was further fabricated with a much smaller time constant τ0(0.38 s)than that of typical activated-carbon supercapacitors,suggesting a quick response frequency.Moreover,the assembled supercapacitor device showed high energy densities of 45.72 and 92.13 Wh kg^(-1) and simultaneously sustained large power densities of 12,526 and 15873 W kg^(-1) under a scan rate of 50 mV s^(-1) in aqueous and solid electrolytes,respectively.Furthermore,the resultant flexible film showed excellent performance in the ORR and can also be used to assemble a strain sensor with an excellent sensing performance for bending strain. | Chuanyin Xiong Mengrui Li Wei Zhao Chao Duan Yonghao Ni | 2020 | Journal of Materiomics2020，6，3： | 6 |

| 15 | Antibacterial and corrosive properties of copper implanted austenitic stainless steel显示文摘Copper ions were implanted into austenitic stainless steel (SS) by metal vapor vacuum arc with a energy of 100 keV and an ions dose range of (0.5-8.0)×1017 cm-2. The Cu-implanted SS was annealed in an Ar atmosphere furnace. Glancing X-ray diffrac-tion (GXRD), transmission electron microscopy (TEM) and Auger electron spectroscopy (AES) were used to reveal the phase compositions, microstructures, and concentration profiles of copper ions in the implanted layer. The results show that the antibacterial property of Cu-implanted SS is attributed to Cu9.9Fe0.1, which precipitated as needles. The depth of copper in Cu-implanted SS with annealing treatment is greater than that in Cu-implanted SS without annealing treatment, which improves the antibacterial property against S. aureus. The salt wetting-drying combined cyclic test was used to evaluate the corrosion-resistance of antibacterial SS, and the results reveal that the antibacterial SS has a level of corrosion-resistance equivalent to that of un-implanted SS. | Juan Xiong Bo-fan Xu Hong-wei Ni | 2009 | International Journal of Minerals,Metallurgy and Materials2009，16，3： | 5 |
| 16 | Optical Micro/Nano Fibers Enabled Smart Textiles for Human-Machine Interface显示文摘Wearable human-machine interface(HMI)is an advanced technology that has a wide range of applications from robotics to augmented/virtual reality(AR/VR).In this study,an optically driven wearable human-interactive smart textile is proposed by integrating a polydimethylsiloxane(PDMS)patch embedded with optical micro/nanofibers(MNF)array with a piece of textiles.Enabled by the highly sensitive pressure dependent bending loss of MNF,the smart textile shows high sensitivity(65.5 kPa^(−1))and fast response(25 ms)for touch sensing.Benefiting from the warp and weft structure of the textile,the optical smart textile can feel slight finger slip along the MNF.Furthermore,machine learning is utilized to classify the touch manners,achieving a recognition accuracy as high as 98.1%.As a proof-of-concept,a remote-control robotic hand and a smart interactive doll are demonstrated based on the optical smart textile.This optical smart textile represents an ideal HMI for AR/VR and robotics applications. | Shuqi Ma Xiaoyu Wang Pan Li Ni Yao Jianliang Xiao Haitao Liu Zhang Zhang Longteng Yu Guangming Tao Xiong Li Limin Tong Lei Zhang | 2022 | Advanced Fiber Materials2022，4，5： | 5 |

| 19 | Reputation-Based Hierarchically Cooperative Spectrum Sensing Scheme in Cognitive Radio Networks显示文摘Cooperative spectrum sensing in cognitive radio is investigated to improve the detection performance of Primary User(PU).Meanwhile,cluster-based hierarchical cooperation is introduced for reducing the overhead as well as maintaining a certain level of sensing performance.However,in existing hierarchically cooperative spectrum sensing algorithms,the robustness problem of the system is seldom considered.In this paper,we propose a reputation-based hierarchically cooperative spectrum sensing scheme in Cognitive Radio Networks(CRNs).Before spectrum sensing,clusters are grouped based on the location correlation coefficients of Secondary Users(SUs).In the proposed scheme,there are two levels of cooperation,the first one is perfonned within a cluster and the second one is carried out among clusters.With the reputation mechanism and modified MAJORITY rule in the second level cooperation,the proposed scheme can not only relieve the influence of the shadowing,but also eliminate the impact of the PU emulation attack on a relatively large scale.Simulation results show that,in the scenarios with deep-shadowing or multiple attacked SUs,our proposed scheme achieves a better tradeoff between the system robustness and the energy saving compared with those conventionally cooperative sensing schemes. | CHEN Huifang XIE Lei NI Xiong | 2014 | China Communications2014，11，1： | 3 |
