| 3 | MdGSTF6,activated by MdMYB1,plays an essential role in anthocyanin accumulation in apple显示文摘Anthocyanins are biosynthesized on the cytosolic surface of the endoplasmic reticulum and then transported into the vacuole for storage.Glutathione S-transferases(GSTs)are considered to be responsible for the transport of anthocyanins into the vacuole.However,the regulatory mechanisms of GSTs in plants are still unclear.Here,we performed a genome-wide analysis and identified 69 GST genes in apple.The expression of MdGSTF6 was positively correlated with the anthocyanin content(r=0.949)during‘Yanfu 8’fruit development.The overexpression of MdGSTF6 in the Arabidopsis thaliana tt19 mutant resulted in seedlings of 35S::MdGSTF6-GFP/tt19 that could accumulate anthocyanin and rescue its phenotype,suggesting that MdGSTF6 was an anthocyanin transporter.The silencing of MdGSTF6 affected anthocyanin accumulation in apple fruit.Moreover,the knockdown of MdGSTF6 by RNA interference in cultured‘Gala’seedlings inhibited anthocyanin accumulation.The interaction experiments showed that MdMYB1 could bind directly to the MdGSTF6 promoter to transcriptionally activate its expression.Collectively,our results demonstrate that MdGSTF6 encodes an important GST transporter of anthocyanins in apple fruit and provide evidence for the associated regulatory mechanisms.Therefore,MdMYB1 can not only regulate anthocyanin synthesis,but also control the transport of anthocyanin in apples.This information may be useful for further clarifying the regulation of anthocyanin transport in apple. | Shenghui Jiang Min Chen Naibo He Xiaoliu Chen Nan Wang Qingguo Sun Tianliang Zhang Haifeng Xu Hongcheng Fang Yicheng Wang Zongying Zhang Shujing Wu Xuesen Chen | 2019 | Horticulture Research2019，6，1： | 16 |
| 4 | Experimental studies on the P-T stability conditions and influencing factors of gas hydrate in different systems显示文摘The P-T stability conditions of gas hydrate in different systems (i.e., solution, silica sand, and marine sediment) were studied using multi-step decomposition method with our experimental equipment. The effects of different ions with various concentrations and sediment grains on the P-T stability conditions of gas hydrate were investigated. The results show that different ions have different influences on the phase equilibrium of gas hydrate. However, the influence of ions is in a similar trend: the larger the concentration, the bigger the P-T curve shifts to the left. For the silica sand, the influence of pore capillarity of coarse particles (> 460 μm) can be negligible. The P-T curve measured in coarse silica is in agreement with that in pure water. However, the influence of pore capillarity of fine particles (< 35 μm) is significant. The maximum reduction value of temperature is 1.5 K for methane hydrate under stable state. The sediment from the South China Sea significantly affects the P-T stability conditions of methane hydrate, with an average reduction value of 1.9 K within the experimental conditions. This is mainly the result of both the pore water salinity and the pore capillarity of sediment. Because the pore water salinity is keeping diluted by the fresh water released from hydrate dissociation, the measured P-T stability points fall on different P-T curves with the decreasing salinity. | LIU ChangLing YE YuGuang SUN ShiCai CHEN Qiang MENG QingGuo HU GaoWei | 2013 | Science China Earth Sciences2013，56，4： | 11 |
| 5 | CD147 antibody specifically and effectively inhibits infection and cytokine storm of SARS-CoV-2 and its variants delta,alpha,beta,and gamma显示文摘SARS-CoV-2 mutations contribute to increased viral transmissibility and immune escape,compromising the effectiveness of existing vaccines and neutralizing antibodies.An in-depth investigation on COVID-19 pathogenesis is urgently needed to develop a strategy against SARS-CoV-2 variants.Here,we identified CD147 as a universal receptor for SARS-CoV-2 and its variants.Meanwhile,Meplazeumab,a humanized anti-CD147 antibody,could block cellular entry of SARS-CoV-2 and its variants-alpha,beta,gamma,and delta,with inhibition rates of 68.7,75.7,52.1,52.1,and 62.3%at 60μg/ml,respectively.Furthermore,humanized CD147 transgenic mice were susceptible to SARS-CoV-2 and its two variants,alpha and beta.When infected,these mice developed exudative alveolar pneumonia,featured by immune responses involving alveoli-infiltrated macrophages,neutrophils,and lymphocytes and activation of IL-17 signaling pathway.Mechanistically,we proposed that severe COVID-19-related cytokine storm is induced by a'spike protein-CD147-CyPA signaling axis':Infection of SARS-CoV-2 through CD147 initiated the JAK-STAT pathway,which further induced expression of cyclophilin A(CyPA);CyPA reciprocally bound to CD147 and triggered MAPK pathway.Consequently,the MAPK pathway regulated the expression of cytokines and chemokines,which promoted the development of cytokine storm.Importantly,Meplazumab could effectively inhibit viral entry and inflammation caused by SARS-CoV-2 and its variants.Therefore,our findings provided a new perspective for severe COVID-19-related pathogenesis.Furthermore,the validated universal receptor for SARS-CoV-2 and its variants can be targeted for COVID-19 treatment. | Jiejie Geng Liang Chen Yufeng Yuan Ke Wang Youchun Wang Chuan Qin Guizhen Wu Ruo Chen Zheng Zhang Ding Wei Peng Du Jun Zhang Peng Lin Kui Zhang Yongqiang Deng Ke Xu Jiangning Liu Xiuxuan Sun Ting Guo Xu Yang Jiao Wu Jianli Jiang Ling Li Kun Zhang Zhe Wang Jing Zhang Qingguo Yan Hua Zhu Zhaohui Zheng Jinlin Miao Xianghui Fu Fengfan Yang Xiaochun Chen Hao Tang Yang Zhang Ying Shi Yumeng Zhu Zhuo Pei Fei Huo Xue Liang Yatao Wang Qingyi Wang Wen Xie Yirong Li Mingyan Shi Huijie Bian Ping Zhu Zhi-Nan Chen | 2021 | Signal Transduction and Targeted Therapy2021，6，10： | 6 |
| 6 | Advances and prospects of PVDF based polymer electrolytes显示文摘Exploring highly foldable batteries with no safety hazard is a crucial task for the realization of portable,wearable,and implantable electric devices.Given these concerns,developing solid-state batteries is one of the most promising routes to achieve this aspiration.Because of the excellent flexibility and processability,polyvinylidene fluoride(PVDF) based electrolytes possess great potential to pack high energy density flexible batteries,however,suffers the various intrinsic shortcomings such as inferior ionic conductivity,a high degree of crystallinity,and lack of reactive groups.Clearing the progress of the present state and concluding the specific challenges faced by PVDF based electrolytes will help to develop PVDF based polymer batteries.In this review,we summarize the recent progress of gel polymer electrolytes and all solid polymer electrolytes based on PVDF.The ion transport mechanisms and preparation methods of PVDF based electrolytes are briefly introduced.Meanwhile,the current design principle and properties of electrolytes are highlighted and systematically discussed.Some peculiar modified strategies performed in lithium-sulfur batteries and lithium-oxygen batteries are also included.Finally,this review describes the challenges and prospects of some solid-state electrolytes to provide strategies for manufacturing high-performance PVDF electrolytes aimed at practical application with flexible requirements. | Yixin Wu Yu Li Yang Wang Qian Liu Qingguo Chen Minghua Chen | 2022 | Journal of Energy Chemistry2022，31，1： | 5 |
| 7 | Dynamic Compression Behavior and Microstructure of a Novel Low-Carbon Quenching-Partitioning-Tempering Steel显示文摘A 0.2C-1.5Mn-1.5Si-0.6Cr-0.05Nb(wt%) steel is treated respectively by novel quenching-partitioning-tempering(Q-P-T) process and traditional quenching and tempering(Q&T) process for comparison. X-ray diffraction analysis indicates that Q-P-T steel has about 10% retained austenite, but Q&T steel hardly has one. With the increase of compression strain rate from 7 9 102 to 5 9 103s-1, the flow stress of Q-P-T steel increases, which demonstrates the positive strain rate effect, but does not exist in Q&T steel. The characterization of scanning electron microscopy indicates that a large number of long, straight martensite laths in Q-P-T steel will bend or be destroyed by large compressive strain of 35%at 5 9 103s-1. However, relative small compressive strain of about 5% at 7 9 102s-1almost does not have any effect on the original lath morphology. The characterization of transmission electron microscopy further reveals the origin of the positive strain rate effect and the microstructural evolution during dynamic compressive deformation. | Qingguo Hao Ying Wang Xiaoshuai Jia Xunwei Zuo Nailu Chen Yonghua Rong | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，3： | 5 |
| 8 | Genome-wide identification of agronomically important genes in outcrossing crops using OutcrossSeq显示文摘Many important crops(e.g.,tuber,root,and tree crops)are cross-pollinating.For these crops,no inbred lines are available for genetic study and breeding because they are self-incompatible,clonally propagated,or have a long generation time,making the identification of agronomically important genes difficult,particularly in crops with a complex autopolyploid genome.In this study,we developed a method,OutcrossSeq,for mapping agronomically important loci in outcrossing crops based on whole-genome low-coverage resequencing of a large genetic population,and designed three computation algorithms in OutcrossSeq for different types of outcrossing populations.We applied OutcrossSeq to a tuberous root crop(sweet potato,autopolyploid),a tree crop(walnut tree,highly heterozygous diploid),and hybrid crops(double-cross populations)to generate high-density genotype maps for the outcrossing populations,which enable precise identification of genomic loci underlying important agronomic traits.Candidate causative genes at these loci were detected based on functional clues.Taken together,our results indicate that OutcrossSeq is a robust and powerful method for identifying agronomically important genes in heterozygous species,including polyploids,in a cost-efficient way.The OutcrossSeq software and its instruction manual are available for downloading at www.xhhuanglab.cn/tool/OutcrossSeq.html. | Mengjiao Chen Weijuan Fan Feiyang Ji Hua Hua Jie Liu Mengxiao Yan Qingguo Ma Jiongjiong Fan Qin Wang Shufeng Zhang Guiling Liu Zhe Sun Changgeng Tian Fengling Zhao Jianli Zheng Qi Zhang Jiaxin Chen Jie Qiu Xin Wei Ziru Chen Peng Zhang Dong Pei Jun Yang Xuehui Huang | 2021 | Molecular Plant2021，14，4： | 4 |
| 9 | Charge Engineering of Mo2C@Defect-Rich N-Doped Carbon Nanosheets for Efficient Electrocatalytic H2 Evolution显示文摘Charge engineering of carbon materials with many defects shows great potential in electrocatalysis,and molybdenum carbide(Mo2C)is one of the noble-metal-free electrocatalysts with the most potential.Herein,we study the Mo2C on pyridinic nitrogen-doped defective carbon sheets(MoNCs)as catalysts for the hydrogen evolution reaction.Theoretical calculations imply that the introduction of Mo2C produces a graphene wave structure,which in some senses behaves like N doping to form localized charges.Being an active electrocatalyst,MoNCs demonstrate a Tafel slope as low as 60.6 mV dec-1 and high durability of up to 10 h in acidic media.Besides charge engineering,plentiful defects and hierarchical morphology also contribute to good performance.This work underlines the importance of charge engineering to boost catalytic performance. | Chunsheng Lei Wen Zhou Qingguo Feng Yongpeng Lei Yi Zhang Yin Chen Jiaqian Qin | 2019 | Nano-Micro Letters2019，11，3： | 4 |

| 11 | ESCRT-dependent vacuolar sorting and degradation of the auxin biosynthetic enzyme YUC1 flavin monooxygenase显示文摘YUC flavin monooxygenases catalyze the ratelimiting step of auxin biosynthesis. Here we report the vacuolar targeting and degradation of GFP-YUC1. GFP-YUC1 fusion expressed in Arabidopsis protoplasts or transgenic plants was primarily localized in vacuoles. Surprisingly, we established that GFP-YUC1, a soluble protein, was sorted to vacuoles through the ESCRT pathway, which has long been recognized for sorting and targeting integral membrane proteins. We further show that GFP-YUC1 was ubiquitinated and in this form GFP-YUC1 was targeted for degradation, a process that was also stimulated by elevated auxin levels. Our findings revealed a molecular mechanism of GFP-YUC1 degradation and demonstrate that the ESCRT pathway can recognize both soluble and integral membrane proteins as cargoes. | Chennan Ge Caiji Gao Qingguo Chen Liwen Jiang Yunde Zhao | 2019 | Journal of Integrative Plant Biology2019，61，9： | 2 |
| 12 | Organic–inorganic hybrid perovskite scintillators for mixed field radiation detection显示文摘Sensitive and fast detection of neutrons and gamma rays is vital for homeland security,high-energy physics,and proton therapy.Fast-neutron detectors rely on light organic scintillators,andγ-ray detectors use heavy inorganic scintillators and semiconductors.Efficient mixed-field detection using a single material is highly challenging due to their contradictory requirements.Here we report hybrid perovskites(C_(8)H_(12)N)_(2)Pb(Br_(0.95)Cl_(0.05))_(4)that combine light organic cations and heavy inorganic skeletons at a molecular level to achieve unprecedented performance for mixed-field radiation detection.High neutron absorption due to a high density of hydrogen,strong radiative recombination within the highly confined[PbX_(6)]^(4-)layer,and sub-nanometer distance between absorption sites and radiative centers,enable a light yield of 41000 photons/MeV,detection pulse width of 2.97 ns and extraordinary linearity response toward both fast neutrons andγ-rays,outperforming commonly used fast-neutron scintillators.Neutron energy spectrum,time-of-flight based fast-neutron/γ-ray discrimination and neutron yield monitoring were all successfully achieved using(C_(8)H_(12)N)_(2)Pb(Br_(0.95)Cl_(0.05))_(4)detectors.We further demonstrate the monitoring of reaction kinetics and total power of a nuclear fusion reaction.We envision that molecular hybridized scintillators open a new avenue for mixed-field radiation detection and imaging. | Mengling Xia Guangda Niu Linyue Liu Runlong Gao Tong Jin Pengying Wan Weicheng Pan Xianpeng Zhang Zuoxiang Xie Sam Teale Zenghua Cai Jiajun Luo Shan Zhao Haodi Wu Shiyou Chen Zhiping Zheng Qingguo Xie Xiaoping Ouyang Edward HSargent Jiang Tang | 2022 | InfoMat2022，4，9： | 2 |
| 13 | A Review of Co-processing of Kitchen Waste and Municipal Residual Sludge显示文摘In this paper,the methods of kitchen waste disposal in recent years were summed up,and the advantages and disadvantages of the current treatment methods were analyzed. At the same time,it has been found that the co-processing of kitchen waste and residual sludge not only has dealt with both kitchen waste and residual sludge,but also the carbon and nitrogen ratio and moisture content of the mixture are balanced,and increases the processing efficiency significantly. It has a certain processing advantage. At present,most research is about the anaerobic digestion of kitchen waste and residual sludge,and the process is more mature,but the study of VFAs accumulation is still insufficient. Aerobic composting is still in the early stage of development,and there are few studies on it at home and abroad. Meanwhile,prospects for the kitchen waste recycling were made in this article. | Han Houfeng Zhuang Pingfang Liu Mei Rong Zhenying Weng Yisong Chen Qingguo Sun Jingya | 2018 | Meteorological and Environmental Research2018，9，4： | 2 |
| 14 | Towards suppressing dielectric loss of GO/PVDF nanocomposites with TA-Fe coordination complexes as an interface layer显示文摘In this work, graphene oxide(GO) nanosheets with surface modification by Tannic and Fe coordination complexes(TA-Fe) were incorporated into poly(vinylidene fluoride)(PVDF) to prepare high constant but low loss polymer nanocomposites, and the effect of TA-Fe interlayer on dielectric properties of the GO@TA-Fe/PVDF nanocomposites was investigated. The results indicate that the dosage, mixing ratio, and reaction time of TA-Fe complexes have obvious influences on the dielectric properties of the nanocomposites. Furthermore, the TA-Fe interlayer significantly influences the electrical properties of GO@TA-Fe nanoparticles and their PVDF composites, and the GO@TA-Fe/PVDF composites exhibit superior dielectric properties compared with raw GO/PVDF. Dielectric losses of the GO@TA-Fe/PVDF are significantly suppressed to a rather low level owing to the presence of TA-Fe layer, which serves as an interlayer between the GO sheets, thus preventing them from direct contacting with each other. Additionally, the dynamic dielectric relaxation of the GO/PVDF and GO@TA-Fe/PVDF nanocomposites was investigated in terms of temperature. | Ying Gong Wenying Zhou Zijun Wang Li Xu Yujia Kou Huiwu Cai Xiangrong Liu Qingguo Chen Zhi-Min Dang | 2018 | Journal of Materials Science & Technology2018，34，12： | 2 |
| 15 | Treatment of Oil Field Wastewater after Chemical Flooding by Fenton Oxidation Combined with Biodegradation显示文摘Wastewater after chemical flooding is difficult to be treated by biological methods due to the residual chemicals in the wastewater.Fenton oxidation,which has been widely applied to detoxifying hazardous organic compounds and improving the biodegradability of these compounds,can solve this problem.So,in this paper,Fenton oxidation was used to enhance the biodegradability of the wastewater after chemical flooding.The optimum operating conditions for the Fenton oxidation process were 2.5 g/L Fe2+,600 mg/L H2O2and 30 min of treatment time.The wastewater pretreated by Fenton oxidation was treated by aerobic activated sludge.It was found that a small amount of H2O2can significantly increase both the biodegradation rate and extent of the wastewater.The effluent CODCrand HPAM contents were 260 and 94 mg/L respectively after the aerobic biological process with the biodegradation time of 24 h.After Fenton oxidation combining with biodegradation,the total CODCrremoval efficiency was up to 90%,and polymer and oil degrading efficiencies were 95%and 92%respectively. | Chen Qingguo Liu Mei | 2015 | Meteorological and Environmental Research2015，6，3： | 2 |
| 16 | Melatonin antagonizes ovarian aging via YTHDF2-MAPK-NF-κB pathway显示文摘Cellular senescence is closely associated with age-related diseases.Ovarian aging,a special type of organ senescence,is the pathophysiological foundation of the diseases of the reproductive system.It is characterized by the loss of integrity of the surface epithelium and a gradual decrease in the number of human ovarian surface epithelial cells(HOSEpiCs).To contribute to the research on delaying ovarian aging,we aimed to investigate the novel epigenetic mechanism of melatonin in protecting HOSEpiCs.We discovered that melatonin has antagonistic effects against the oncogene-induced senescence(OIS)of HOSEpiCs.Mechanistically,the oncogene Ras decreased the expression of YTHDF2,which is the reader of RNA-m6A,by stimulating the generation of reactive oxygen species(ROS).Moreover,we found that the suppression of YTHDF2 increased the expression of MAP2K4 and MAP4K4 by enhancing the stability of the transcription of their mRNAs,thereby upregulating the expression of the senescence-associated secretory phenotype(SASP)through the activation of the MAP2K4 and MAP4K4-dependent nuclear factor-κB(NF-κB)signaling pathways.We further determined that melatonin has antagonistic effects against the OIS of HOSEpiCs by inhibiting the ROS-YTHDF2-MAPK-NF-κB pathway.These findings provide key insights into the potential avenues for preventing and treating ovarian aging. | Ruigong Zhu Xian Ji Xuan Wu Jiajing Chen Xuesong Li Hong Jiang Haiping Fu Hui Wang Zhe Lin Xin Tang Shixiu Sun Qingguo Li Bingjian Wang Hongshan Chen | 2022 | Genes & Diseases2022，9，2： | 2 |
| 17 | Simplified Calculation Method for Transient Field of Transverse Electromagnetic Horn Antenna Used by High-altitude Electromagnetic Pulse Simulator显示文摘For conveniently calculating the radiated electric field of transverse electromagnetic(TEM) horn antenna,an approximate simplified analytical calculation method is suggested.This method divides the horn to a system of V-antennas and superimposes the fields of all V-antennas to obtain the field of the TEM horn.The method is compared with the traditional analytical method and numerical method.The obtained results suggest that the proposed method is valid,simple and that it can fastly calculate the radiated electric field of the TEM horn antenna in an arbitrary space with an arbitrary excitation voltage.Based on this method,radiation of the TEM horn antenna of a high-altitude electromagnetic pulse(HEMP) simulator is simulated.Rise time,pulse width,peak value of electric field,and field distribution are analyzed.Results show that the TEM horn antenna can be used in HEMP simulators: the near field waveform is closer to the standard waveform than to the far field waveform; the standards for the rise time and the peak value of electric field are easily satisfied; the pulse width of the radiated field can be increased by broadening the pulse width of an excitation source and by making the antenna of a proper | WANG Yun CHEN Yongguang WANG Qingguo | 2013 | 高电压技术2013，39，10： | 2 |

| 20 | Capacity fading of spinel LiMn_2O_4 during cycling at elevated temperature显示文摘A normal spinel LiMn2O4 as cathode material for lithium-ion cells was cycled galvanostatically (0.2C) at 55℃. To determine the contribution of each voltage plateau to the total capacity fading of the cathode upon repeated cycling, the capacities in each plateau were separated by differentiation of voltage vs. capacity. The results show that the capacity fading in the upper voltage plateau is more rapidly than that in the lower during discharging, while in charging process, it fades slower than that in the lower voltage range. The increased capacity shift and aggravated self-discharge/electrolyte oxidation during discharging contribute to a high fading rate in the upper step. Capacity shift also takes place during charging process, which again enhancing the fading rate of the lower voltage plateau. An increase in capacity shift, as a result of an increase in polarization of the cell, plays a major role in determining the fading rate in each voltage plateau, further reflecting the thickening of the | Yanbin Chen and Qingguo LiuLaboratory of Solid State Ionics, University of Science and Technology Beijing, Beijing 100083, China (Received 2001-09-20) | 2002 | Journal of University of Science and Technology Beijing2002，9，3： | 1 |
