| 1 | Haze observations by simultaneous lidar and WPS in Beijing before and during APEC, 2014显示文摘We present combined Mie lidar, ozone lidar and wide-range particle spectrometer observations which were carried out in Beijing, north China during two periods—one haze period before the Asia-Pacific Economic Cooperation(APEC) meeting and one moderate pollution period during the meeting in 2014. High extinction coefficient, moderate ozone concentration and variable particle number concentration were obtained throughout the first haze observation period. The mean extinction coefficients in the two pollution periods were 0.52 and 0.23 km?1, respectively, at 532 nm. The ozone concentration during the first haze phase was more various with a higher average value of 49 ppb compared with that in the second pollution observations(32 ppb). Compared with the same metrological condition occurring at the end of October, the sharply decreased aerosol extinction coefficient and ozone concentration show the effectiveness of the emission-cutting measures implemented during APEC in November. The comparison of aerosols and ozone in different heights indicate different pollution sources and the complicated ozone process of generation and disappearance. The correlation between the scattering coefficient and particle number concentrations of various diameter depended on the ambient humidity. Especially the particle number concentration(500 nm–1 ?m) contributed most to PM2.5 concentration. The four-day back trajectories from a Hybrid Single-particle Lagrangian Integrated Trajectory(HYSPLIT) model indicate that the air masses in the lower boundary layer before and during APEC were advected from the densely populated south regions of China and the long pollution transportation passing through northern China. | Zhenyi Chen Jiaoshi Zhang Tianshu Zhang Wenqing Liu Jianguo Liu | 2015 | Science China Chemistry2015，58，9： | 14 |
| 2 | Vertical Distribution Characteristics of PM2.5 Observed by a Mobile Vehicle Lidar in Tianjin, China in 2016显示文摘We present mobile vehicle lidar observations in Tianjin, China during the spring, summer, and winter of 2016. Mobile observations were carried out along the city border road of Tianjin to obtain the vertical distribution characteristics of PM_(2.5). Hygroscopic growth was not considered since relative humidity was less than 60% during the observation experiments. PM_(2.5) profile was obtained with the linear regression equation between the particle extinction coefficient and PM_(2.5) mass concentration. In spring, the vertical distribution of PM_(2.5) exhibited a hierarchical structure. In addition to a layer of particles that gathered near the ground, a portion of particles floated at 0.6–2.5-km height. In summer and winter, the fine particles basically gathered below 1 km near the ground. In spring and summer, the concentration of fine particles in the south was higher than that in the north because of the influence of south wind. In winter, the distribution of fine particles was opposite to that measured during spring and summer. High concentrations of PM_(2.5) were observed in the rural areas of North Tianjin with a maximum of 350 μg m–3 on 13 December2016. It is shown that industrial and ship emissions in spring and summer and coal combustion in winter were the major sources of fine particles that polluted Tianjin. The results provide insights into the mechanisms of haze formation and the effects of meteorological conditions during haze–fog pollution episodes in the Tianjin area. | Lihui LYU Yunsheng DONG Tianshu ZHANG Cheng LIU Wenqing LIU Zhouqing XIE Yan XIANG Yi ZHANG Zhenyi CHEN Guangqiang FAN Leibo ZHANG Yang LIU Yuchen SHI Xiaowen SHU | 2018 | Journal of Meteorological Research2018，32，1： | 5 |

| 4 | GDSL esterase/lipases OsGELP34 and OsGELP110/OsGELP115 are essential for rice pollen development显示文摘Pollen exine contains complex biopolymers of aliphatic lipids and phenolics.Abnormal development of pollen exine often leads to plant sterility.Molecular mechanisms regulating exine formation have been studied extensively but remain ambiguous.Here we report the analyses of three GDSL esterase/lipase protein genes,OsGELP34,OsGELP110,and OsGELP115,for rice exine for-mation.OsGELP34 was identified by cloning of a male sterile mutant gene.OsGELP34 encodes an endoplasmic reticulum protein and was mainly expressed in anthers during pollen exine formation.osgelp34 mutant displayed abnormal exine and altered expression of a number of key genes required for pollen development.OsGELP110 was previously identified as a gene differentially expressed in meiotic anthers.OsGELP110 was most homologous to OsGELP115,and the two genes showed similar gene expression patterns.Both OsGELP110 and OsGELP115 proteins were localized in peroxisomes.Individual knockout of OsGELP110 and OsGELP115 did not affect the plant fertility,but double knockout of both genes altered the exine structure and rendered the plant male sterile.OsGELP34 is distant from OsGELP110 and OsGELP115 in sequence,and osgelp34 and osgelp110/osgelp115 mutants were different in anther morphology despite both were male sterile.These results suggested that OsGELP34 and OsGELP110/OsGELP115 catalyze different compounds for pollen exine development. | Huihui Zhang Menglong Wang Yiqi Li Wei Yan Zhenyi Chang Haoling Ni Zhufeng Chen Jianxin Wu Chunjue Xu Xing Wang Deng Xiaoyan Tang | 2020 | Journal of Integrative Plant Biology2020，62，10： | 4 |
| 5 | A viral protein orchestrates rice ethylene signaling to coordinate viral infection and insect vector-mediated transmission显示文摘Arthropod-borne viruses cause serious threats to human health and global agriculture by rapidly spreading via insect vectors. Southern rice black-streaked dwarf virus (SRBSDV) is the most damaging rice-infecting virus that is frequently transmitted by planthoppers. However, the molecular mechanisms underlying its propagation in the host plants and epidemics in the field are largely unknown. Here, we showed that the SRBSDV-encoded P6 protein is a key effector that regulates rice ethylene signaling to coordinate viral infection and transmission. In early SRBSDV infection, P6 interacts with OsRTH2 in the cytoplasm to activate ethylene signaling and enhance SRBSDV proliferation;this also repels the insect vector to reduce infestation. In late infection, P6 enters the nucleus, where it interacts with OsEIL2, a key transcription factor of ethylene signaling. The P6-OsEIL2 interaction suppresses ethylene signaling by preventing the dimerization of OsEIL2, thereby facilitating viral transmission by attracting the insect vector. Collectively, these findings reveal a novel molecular mechanism by which an arbovirus modulates the host defense system to promote viral infection and transmission. | Yaling Zhao Xue Cao Weihua Zhong Shunkang Zhou Zhanbiao Li Hong An Xiahua Liu Ruifeng Wu Surakshya Bohora Yan Wu Zhenyi Liang Jiahao Chen Xin Yang Guohui Zhou Tong Zhang | 2022 | Molecular Plant2022，15，4： | 4 |
| 6 | Signaling pathways and targeted therapies in lung squamous cell carcinoma: mechanisms and clinical trials显示文摘Lung cancer is the leading cause of cancer-related death across the world.Unlike lung adenocarcinoma,patients with lung squamous cell carcinoma(LSCC)have not benefitted from targeted therapies.Although immunotherapy has significantly improved cancer patients’outcomes,the relatively low response rate and severe adverse events hinder the clinical application of this promising treatment in LSCC.Therefore,it is of vital importance to have a better understanding of the mechanisms underlying the pathogenesis of LSCC as well as the inner connection among different signaling pathways,which will surely provide opportunities for more effective therapeutic interventions for LSCC.In this review,new insights were given about classical signaling pathways which have been proved in other cancer types but not in LSCC,including PI3K signaling pathway,VEGF/VEGFR signaling,and CDK4/6 pathway.Other signaling pathways which may have therapeutic potentials in LSCC were also discussed,including the FGFR1 pathway,EGFR pathway,and KEAP1/NRF2 pathway.Next,chromosome 3q,which harbors two key squamous differentiation markers SOX2 and TP63 is discussed as well as its related potential therapeutic targets.We also provided some progress of LSCC in epigenetic therapies and immune checkpoints blockade(ICB)therapies.Subsequently,we outlined some combination strategies of ICB therapies and other targeted therapies.Finally,prospects and challenges were given related to the exploration and application of novel therapeutic strategies for LSCC. | Zhenyi Niu Runsen Jin Yan Zhang Hecheng Li | 2022 | Signal Transduction and Targeted Therapy2022，7，11： | 3 |
| 7 | A flexible conductive hybrid elastomer for high-precision stress/strain and humidity detection显示文摘Flexible and environment-responsive materials are essential for a large number of applications from artificial skin to wearable devices. The present study develops a flexible, ultra-low cost conductive hybrid elastomer(CHE), which possesses high responsive capabilities to stress/strain and humidity. CHE was composed of polydimethylsiloxane(PDMS) and starch hydrogel(SH), enabling great elasticity(56 kPa),high conductivity(10^(-2)S/m) and high sensitivity to external stimuli(gauge factor of CHE under stress and strain are 0.71 and 2.22, respectively, and sensitivity to humidity is 1.2 × 10^(-6)S/m per RH%). These properties render CHE a promising candidate for artificial skin and wearable electronics applications of continuously monitoring environmental information. | Haoran Liu Zhenyi Zhang Jun Ge Xiao Lin Xinye Ni Huilin Yang Lei Yang | 2019 | Journal of Materials Science & Technology2019，35，1： | 2 |
| 8 | Influence of Sanao Tang on urine volume and expression of aquaporin 2 in rats with respiratory function impairment induced by passive smoking and lipopolysaccharide显示文摘OBJECTIVE: To investigate the effect of Sanao Tang(SAT) on urine volume and the expression of aquaporin-2(AQP2) in rats with lung dysfunction induced by passive smoking and lipopolysaccharide.METHODS: Totally 45 healthy Specific pathogen Free Wistar Rats were randomized into 3 groups:normal control group, model group and SAT group.A rat model of respiratory dysfunction induced by exposure to cigarette smoking and lipopolysaccharide(LPS). Lavage of decoction of the Chinese medicine was performed for rats in the SAT group. Anires 2005 System was used to analyze the pulmonary function. Urine of rats was collected through metabolism cage method. Enzyme-linked immunosorbent assay(ELISA) was used to determine content of antidiuretic hormone(ADH), angiotensin Ⅱ(AngⅡ), atrial natriuretic factor(ANP), endothelin 1(ET-1), nitric oxide(NO) and prostaglandin E2(PGE2) in serum, lung and kidney. The expression of AQP2 in rat renal tissue was determined with real-time fluorescence quantitative PCR(RT-PCR).RESULTS:(a) In comparison with the normal control, It was found that enforced vital capacity(FVC),1-second forced expiratory volume/forced vital capacity%(FEV1/FVC%), 24 h urine volume content of NO and PGE2 were decreased, while AQP2 m RNA level and content of ADH, Agn Ⅱ, ANP and ET-1were increased in the model group with statistical significance(P < 0.05).(b) In comparison with the model group, It was found that FVC, FEV1, FEV1/FVC%, 24 h urine volume, content of PGE2 and NO decreased, while AQP2 m RNA level, content of ANP,ADH and AngⅡ decreased in the SAT group with statistical significance(P < 0.05).CONCLUSION: SAT might effectively regulate the urine volume in the modeled rats; ADH, Ang Ⅱ,ANP, ET-1, NO and PGE2 might play an important role in the regulation on urine volume by lungs.This might be the mechanisms underpinning the function of lung governing water passage in terms of the theory of Traditional Chinese Medicine. | Zhang Jinchao Sun Yan Zhang Shujing Gao Yushan Wang Zhenyi Liu Xiaolei Yang Jiamin Li Yuhang | 2016 | Journal of Traditional Chinese Medicine2016，36，6： | 2 |

| 11 | Electrospun Semiconductor-Based Nano-Heterostructures for Photocatalytic Energy Conversion and Environmental Remediation:Opportunities and Challenges显示文摘Harvesting solar energy to drive the semiconductor photocatalysis offers a promising tactic to address ever-growing challenges of both energy shortage and environmental pollution.Design and synthesis of nano-heterostructure photocatalysts with controllable components and morphologies are the key factors for achieving highly efficient photocatalytic processes.Onedimensional(1D)semiconductor nanofibers produced by electrospinning possess a large ratio of length to diameter,high ratio of surface to volume,small grain sizes,and high porosity,which are ideally suited for photocatalytic reactions from the viewpoint of structure advantage.After the secondary treatment of these nanofibers through the solvothermal,gas reduction,in situ doping,or assembly methods,the multi-component nanofibers with hierarchical nano-heterostructures can be obtained to further enhance their light absorption and charge carrier separation during the photocatalytic processes.In recent years,the electrospun semiconductorbased nano-heterostructures have become a“hot topic”in the fields of photocatalytic energy conversion and environmental remediation.This review article summarizes the recent progress in electrospinning synthesis of various kinds of high-performance semiconductor-based nano-heterostructure photocatalysts for H2 production,CO_(2) reduction,and decomposition of pollutants.The future perspectives of these materials are also discussed. | Na Lu Mingyi Zhang Xuedong Jing Peng Zhang Yongan Zhu Zhenyi Zhang | 2023 | Energy & Environmental Materials2023，6，2： | 1 |

| 14 | One-step hydrothermal synthesis of S-defect-controlled ZnIn_(2)S_(4) microflowers with improved kinetics process of charge-carriers for photocatalytic H_(2) evolution显示文摘Engineering lattice defects in two-dimensional(2 D) sulfide semiconductors has been accepted as an effective strategy to enhance the efficiency of the solar-to-fuels conversion.Although many researches have proven the lattice defect-mediated photocatalytic activity of ZnIn_(2)S_(4),the artificial control of Sdefects for optimizing the charge-carrier kinetics process in ZnIn_(2)S_(4) has long been a challenging task.Herein,we report a facile one-step method to modulate the lattice S-content of ZnIn_(2)S_(4) microflowers(MFs) only through adjusting the used amount of S-precursor in the hydrothermal solution that contains the metal precursors with a fixed Zn/In stoichiometric ratio at 1:2.We also demonstrated that the Svacancies at the In facets were the main type of lattice defects in the formed ZnIn_(2)S_(4) MFs,which could enhance both the separation and migration processes of the photoinduced charge-carriers due to the existence of discrete defect energy-levels(DELs) and the reduced effective mass of electrons,as evidenced by the first-principles calculations and the electron spectra analyses.The ZnIn_(2)S_(4) MFs with the optimal content of S-vacancy obtained by a hydrothermal treatment of the precursors with the Zn/In/S stoichiometric ratio of 1:2:8 possessed the long-lived photoinduced electron(~94.64 ns) for contributing to the photo-physical and-chemical processes.Thus,upon visible light irradiation,the H_(2)-evolution rate of this sample reached ~2.40 mmol h^(-1) g^(-1) with an apparent quantum efficiency of ~0.16% at 420 nm even though only using 5 mg of photocatalysts without any cocatalysts. | Xuedong Jing Na Lu Jindou Huang Peng Zhang Zhenyi Zhang | 2021 | Journal of Energy Chemistry2021，30，7： | 1 |
| 15 | Science with the 2.5-meter Wide Field Survey Telescope(WFST)显示文摘The Wide Field Survey Telescope(WFST) is a dedicated photometric surveying facility being built jointly by University of Science and Technology of China(USTC) and the Purple Mountain Observatory(PMO). It is equipped with a 2.5-meter diameter primary mirror, an active optics system, and a mosaic CCD camera with 0.73 gigapixels on the primary focal plane for highquality image capture over a 6.5-square-degree field of view. The installation of WFST near the summit of Saishiteng mountain in the Lenghu region is scheduled in summer of 2023, and the operation is planned to start three months later. WFST will scan the northern sky in four optical bands(u, g, r and i) at cadences from hourly/daily in the deep high-cadence survey(DHS) program, to semi-weekly in the wide field survey(WFS) program. During a photometric night, a nominal 30 s exposure in the WFS program will reach a depth of 22.27, 23.32, 22.84, and 22.31(AB magnitudes) in these four bands, respectively, allowing for the detection of a tremendous amount of transients in the low-z universe and a systematic investigation of the variability of Galactic and extragalactic objects. In the DHS program, intranight 90 s exposures as deep as 23(u) and 24 mag(g), in combination with target of opportunity follow-ups, will provide a unique opportunity to explore energetic transients in demand for high sensitivities, including the electromagnetic counterparts of gravitational wave events, supernovae within a few hours of their explosions,tidal disruption events and fast, luminous optical transients even beyond redshift of unity. In addition, the final 6-year co-added images, anticipated to reach g■25.8 mag in WFS or 1.5 mags deeper in DHS, will be of fundamental importance to general Galactic and extragalactic science. The highly uniform legacy surveys of WFST will serve as an indispensable complement to those of the Vera C. Rubin Observatory's Legacy Survey of Space and Time(LSST) that monitors the southern sky. | Tinggui Wang Guilin Liu Zhenyi Cai Jinjun Geng Min Fang Haoning He Ji-an Jiang Ning Jiang Xu Kong Bin Li Ye Li Wentao Luo Zhizheng Pan Xuefeng Wu Ji Yang Jiming Yu Xianzhong Zheng Qingfeng Zhu Yi-Fu Cai Yuanyuan Chen Zhiwei Chen Zigao Dai Lulu Fan Yizhong Fan Wenjuan Fang Zhicheng He Lei Hu Maokai Hu Zhiping Jin Zhibo Jiang Guoliang Li Fan Li Xuzhi Li Runduo Liang Zheyu Lin Qingzhong Liu Wenhao Liu Zhengyan Liu Wei Liu Yao Liu Zheng Lou Han Qu Zhenfeng Sheng Jianchun Shi Yiping Shu Zhenbo Su Tianrui Sun Hongchi Wang Huiyuan Wang Jian Wang Junxian Wang Daming Wei Junjie Wei Yongquan Xue Jingzhi Yan Chao Yang Ye Yuan Yefei Yuan Hongxin Zhang Miaomiao Zhang Haibin Zhao Wen Zhao | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，10： | 1 |
| 16 | Deciphering the Role of Fluoroethylene Carbonate towards Highly Reversible Sodium Metal Anodes显示文摘Sodium metal anodes(SMAs)sufer from extremely low reversibility(<20%)in carbonate based clectrolytes-this piece of knowledge gained from previous studics has ruled out the application of carbonate solvents for sodium metal batteries.Here,we overturn this conclusion by incorporating fluoroethylene carbonate(FEC)as cosolvent that renders a Na plating/stripping fficiency of>95%with conventional NaPF。salt at a regular concentration(1.0M).The peculiar role of FEC is firstly.unraveled via its involvement into the solvation structure,where a threshold FEC concentration with a coordination number>1.2 is needed in guaranteeing high Na reversibility over the long-term.Specifially,by incorporating an average number of 1.2 FEC molecules into the primary Na*solvation sheath,lowest unoccupied molecular orbital(LUMO)levels of such Nat-FEC solvates undergo further decrease,with spin electrons residing either on the O=C 0(O)moiety of FEC or sharing between Na*and its C=:O bond,which ensures a prior FEC decomposition in passivating the Na surface against other carbonate molecules.Further,by adopting cryogenic tranmission electron microscopy(cryo-TEM),we found that the Na filaments grow into substantially larger diameter from-400nm to>1 pum with addition of FEC upon the threshold value.A.highly crstalline and much thiner(-40 nm)slid-electrolyte interphase(SED)is consequently observed to uniformly wrap the Na surface,in contrast to the severely corroded Na as retrieved from the blank electrolyte.The potence of FEC is further demonstrated in a series of'corrosive solvents'such as ethy!l acetate(EA)。trimethyl phosphate(TMP),and actonitrile(AN)enabling highly reversible SMAs in the otherwise unusable solvent systems. | Xueying Zheng Suting Weng Wei Luo Bo Chen Xiao Zhang Zhenyi Gu Haotian Wang Xiaolu Ye Xuyang Liu Liqiang Huang Xinglong Wu Xuefeng Wang Yunhui Huang | 2022 | Research2022，，2： | 1 |

| 19 | Simulating androgen receptor selection in designer yeast显示文摘Androgen receptor(AR)mutation is closely associated with prostate cancer(PCa)and is one of the mechanisms of resistance to PCa therapies such as AR antagonists.Although sequencing technologies like next-generation sequencing(NGS)contributes to the high-throughput and precise detection of AR mutations carried by PCa patients,the lack of interpretations of these clinical genetic variants has still been a roadblock for PCa-targeted precision medicine.Here,we established a designer yeast reporter assay to simulate natural androgen receptor(AR)selection using AR antagonists.Yeast HIS3 gene transactivation was associated with the ligand-induced recruitment of steroid receptor coactivator-1(SRC-1)by AR mutants,where yeast growth in histidine-free medium was determined as the outcome.This assay is applicable to determine a wide range of clinical AR mutants including those with loss of function relating to androgen insensitivity syndrome(AIS),and those associated with PCa conferring resistance to AR antagonists such as enzalutamide(ENZ),bicalutamide(BIC),and cyproterone acetate(CPA).One clinical AR mutant previously reported to confer ENZ-resistance,F877L,was found to confer partial resistance to CPA as well using designer yeast.Our simple and efficient assay can enable precise one-pot screening of AR mutants,providing a reference for tailored medicine. | Haoran Zhang Lu Zhang Yipeng Xu Shaoyong Chen Zhenyi Ma Mingdong Yao Fangyin Li Bo Li Yingjin Yuan | 2022 | Synthetic and Systems Biotechnology2022，7，4： | 0 |
| 20 | Sulfonate-Functionalized Polyoxovanadate-Based Metal-Organic Polyhedra for Enhanced Proton Conduction via the Synergy of Linker and Metal Cluster Vertex显示文摘Metal-organic polyhedra(MOPs)have emerged as novel porous platforms for proton conduction,however,the concerted employment of both linker and metal cluster vertex is rarely applied for the fabrication of MOPs-based high conducting materials.Herein we report the synthesis of sulfonate-functionalized polyoxovanadate-based MOPs for enhanced proton conduction via the synergistic effect from linker and metal cluster node.MOPs 1 and 2 exhibit octahedral cage configuration constructed from{V_(5)O_(9)Cl}vertex and 5-sulfoisophthalate linker.Owing to the ordered packing of octahedral cages along three axes,3D interpenetrated open channels that are lined with high-density sulfonates are thus formed within 2.Coupled with the proton-conductive{V_(5)O_(9)Cl}vertexs as well as protonated counterions,an extensive H-bonded network is therefore generated for facile proton transfer.2 exhibits high proton conductivity of 3.02×10^(-2)S cm^(-1)at 65℃under 90%RH,recording the highest value for MOPs pellet sample.This value is enhanced~1order of magnitude compared with that of carboxylate-functionalized analogue 3,clearly illustrating the advantage of combining linker and metal cluster node for enhanced proton conduction.This work will further promote the exploitation of high proton conductive MOPs-based materials by the synergy design strategy. | Yu Zhang Shan-Shan Liu Bo Li Hanqi You Longxi Zhang Zhenyi Zhang Hong-Ying Zang Qi Zheng Weimin Xuan | 2022 | Chinese Journal of Structural Chemistry2022，41，8： | 0 |
