2Outbreak of Dengue Fever in Central China,2013显示文摘In 2013,the first dengue fever(DF) outbreak in central China was reported in the central of Henan province,northern temperate regions,although they have been sequentially recorded in Southern China.106 suspected DF cases were reported and 73 patients were confirmed dengue virus type 3(DEN-3) infections.62/392(15.8%) local health persons showed DEN antibodies positive.To this day Henan is the northernmost province in China which has been reported about outbreak of DF and what is important is that it warns us the endemic range of DF has been expanded geographically in China.HUANG Xue Yong MA Hong Xia WANG Hai Feng DU Yan Hua SU Jia LI Xing Le TANG Xiao Yan MA Hong Peng ZU Bing Can ZHANG Qiao Hong CHEN Hao Min XU Bian Li 2014Biomedical and Environmental Sciences2014,27,11:30
3The recommendations of Chinese Parkinson’s disease and movement disorder society consensus on therapeutic management of Parkinson’s disease显示文摘Background:Parkinson’s disease(PD)is a chronic,progressive and debilitating disease,which affects over 2.5 million people in China.PD is characterized clinically by resting tremor,muscular rigidity,bradykinesia and postural instability.As the disease progresses,additional complications can arise such as non-motor and neurobehavioral symptoms.Pharmacological treatment and surgical intervention for PD have been implemented in China.Until 10 years ago,there was lack of standardization for the management of PD in different regions and among different physicians,leading to different treatment levels in different regions and different physicians.Since then,the Chinese Parkinson’s Disease and Movement Disorder Society have published three versions of guidelines for the management of PD in China,in 2006,2009 and 2014,respectively.Correspondingly,the overall level of treatment for PD in China improved.Objectives:To update the treatment guidelines based on current foreign and domestic practice guidelines and clinical evidence,and to improve the treatment options available to physicians in the management of PD.Summary:A variety of treatment recommendations in the treatment guidelines have been proposed,including physical activity and disease-modifying medication,which should be initiated at the early-stage of the disease.The principles of dosage titration should be followed to avoid acute adverse reactions to the drugs,to achieve a satisfactory clinical effect with a low dose and to reduce the incidence of long-term motor complications.Moreover,different treatment strategies should be considered at different stages of the disease.Importantly,treatment guidelines and personalized treatments should be valued equally.A set of treatment recommendations has been developed to assist physicians to improve and optimize clinical outcomes for patients with PD in China.Shengdi Chen Piu Chan Shenggang Sun Haibo Chen Baorong Zhang Weidong Le Chunfeng Liu Guoguang Peng Beisha Tang Lijuan Wang Yan Cheng Ming Shao Zhenguo Liu Zhenfu Wang Xiaochun Chen Mingwei Wang Xinhua Wan Huifang Shang Yiming Liu Pingyi Xu Jian Wang Tao Feng Xianwen Chen Xingyue Hu Anmu Xie Qin Xiao 2016Translational Neurodegeneration2016,5,1:23
4The first all-season sample set for mapping global land cover with Landsat-8 data显示文摘We report the world's first all-season training and validation sample sets for global land cover classification with Landsat-8 data.Prior to this,such samples were only available at a single date primarily from the growing season.It is unknown how much limitation such a single-date sample has to mapping global land cover in other seasons of the year.To answer this question,we selected available Landsat-8 images from four seasons and collected training and validation samples from them.We compared the performances of training samples in different seasons using Random Forest algorithm.We found that the use of training samples from any individual season would result in the best overall classification accuracy when validated by samples in the same season.The global overall accuracy from combined best seasonal results was 67.2% when classifying the 11 Level-1 classes in the Finer Resolution Observation and Monitoring of Global Land Cover(FROM-GLC) classification system.The use of training samples from all seasons(named all-season training sample set hereafter) produced an overall accuracy of 67.0%.We also tested classification within 10° latitude 60° longitude zones using all-season training subsample within each zone and obtained an overall accuracy of 70.2%.This indicates that properly grouped subsamples in space can help improve classification accuracies.All the results in this study seem to suggest that it is possible to use an all-season training sample set to reach global optimality with universal applicability in classifying images acquired at any time of a year for global land cover mapping.Congcong Li Peng Gong Jie Wang Zhiliang Zhu Gregory S.

6Methylated and thiolated arsenic species for environmental and health research——A review on synthesis and characterization显示文摘Hundreds of millions of people around the world are exposed to elevated concentrations of inorganic and organic arsenic compounds, increasing the risk of a wide range of health effects. Studies of the environmental fate and human health effects of arsenic require authentic arsenic compounds. We summarize here the synthesis and characterization of more than a dozen methylated and thiolated arsenic compounds that are not commercially available. We discuss the methods of synthesis for the following14 trivalent(Ⅲ) and pentavalent() arsenic compounds: monomethylarsonous acid(MMA~Ⅲ), dicysteinylmethyldithioarsenite(MMA~Ⅲ(Cys)_2), monomethylarsonic acid(MMA~Ⅴ),monomethylmonothioarsonic acid(MMMTAⅤ) or monothio-MMA~Ⅴ, monomethyldithioarsonic acid(MMDTA~Ⅴ) or dithio-MMA~Ⅴ, monomethyltrithioarsonate(MMTTA~Ⅴ) or trithio-MMA~Ⅴ,dimethylarsinous acid(DMA~Ⅲ), dimethylarsino-glutathione(DMA~Ⅲ(SG)), dimethylarsinic acid(DMA~Ⅴ), dimethylmonothioarsinic acid(DMMTA~Ⅴ) or monothio-DMAⅤ, dimethyldithioarsinic acid(DMDTA~Ⅴ) or dithio-DMA~Ⅴ, trimethylarsine oxide(TMAO~Ⅴ), arsenobetaine(AsB), and an arsenicin-A model compound. We have reviewed and compared the available methods,synthesized the arsenic compounds in our laboratories, and provided characterization information. On the basis of reaction yield, ease of synthesis and purification of product, safety considerations, and our experience, we recommend a method for the synthesis of each of these arsenic compounds.William R.Cullen Qingqing Liu Xiufen Lu Anthony McKnight-Whitford Hanyong Peng Aleksandra Popowich Xiaowen Yan Qi Zhang Michael Fricke Hongsui Sun X.Chris Le 2016Journal of Environmental Sciences2016,28,11:12
7Validation of the chinese version of the EORTC QLQ-CR29 in patients with colorectal cancer显示文摘AIM To assess the validity and reliability of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Colorectal Cancer 29(EORTC QLQ-CR29) in Chinese patients with colorectal cancer(CRC). METHODS From March 2014 to January 2015, 356 patients with CRC from four different hospitals in China were enrolled in the study, and all patients self-administered the EORTC QLQ-CR29 and the quality of life core questionnaire(EORTC QLQ-C30). Evaluation of the scores was based on the Karnofsky Performance Scale(KPS). The reliability and validity of the questionnaires were assessed by Cronbach's α coefficient, the Spearman correlation test and Wilcoxon rank sum test.RESULTS The EORTC QLQ-CR29 showed satisfactory reliability(α > 0.7), although the urinary frequency and blood and mucus in stool dimensions had only moderate reliability(α = 0.608). The multitrait scaling analyses showed good convergent(r > 0.4) and discriminant validity. Significant differences were obtained for each item in the different KPS subgroups(KPS ≤ 80; KPS > 80). body image and most single-item dimensions showed statistically significant differences in patients with a stoma compared with the rest of the patients. CONCLUSION The EORTC QLQ-CR29 exhibits high validity and reliability in Chinese patients with CRC, and can therefore be recommended as a valuable tool for the assessment of quality of life in these patients.Jin-bo Lin Lei Zhang Dong-Wen Wu Zhou-Huan xi xue-Jun Wang Yun-Shou Lin Wakana Fujiwara Jing-Ru Tian Min Wang Peng Peng Ai Guo Zhen Yang Le Luo Ling-Ya Jiang Qia-Qia Li xue-Ying Zhang Yun-Feng Zhang Hou-Wei xu bing Yang xun-Lin Li Yi-xiong Lei 2017World Journal of Gastroenterology2017,23,10:12
8A plasmonic route for the integrated wireless communication of subdiffraction-limited signals显示文摘Perfect lenses,superlenses and time-reversal mirrors can support and spatially separate evanescent waves,which is the basis for detecting subwavelength information in the far field.However,the inherent limitations of these methods have prevented the development of systems to dynamically distinguish subdiffraction-limited signals.Utilizing the physical merits of spoof surface plasmon polaritons(SPPs),we demonstrate that subdiffraction-limited signals can be transmitted on planar integrated SPP channels with low loss,low channel interference,and high gain and can be radiated with a very low environmental sensitivity.Furthermore,we show how deep subdiffraction-limited signals that are spatially coupled can be distinguished after line-of-sight wireless transmission.For a visualized demonstration,we realize the high-quality wireless communication of two movies on subwavelength channels over the line of sight in real time using our plasmonic scheme,showing significant advantages over the conventional methods.Hao Chi Zhang Le Peng Zhang Pei Hang He Jie Xu Cheng Qian Francisco J.Garcia-Vidal Tie Jun Cui 2020Light(Science & Applications)2020,9,1:8
9A Resource for Inactivation of MicroRNAs Using Short Tandem Target Mimic Technology in Model and Crop Plants显示文摘microRNAs (miRNAs)are endogenous small non-coding RNAs that bind to mRNAs and target them for cleavage and/or translational repression,leading to gene silencing.We previously developed short tandem target mimic (STTM)technology to deactivate endogenous miRNAs in Arabidopsis.Here,we created hundreds of STTMs that target both conserved and species-specific miRNAs in Arabidopsis,tomato,rice,and maize,providing a resource for the functional interrogation of miRNAs.We not only revealed the functions of several miRNAs in plant development,but also demonstrated that tissue-specific inactivation of a few miRNAs in rice leads to an increase in grain size without adversely affecting overall plant growth and development.RNA-seq and small RNAseq analyses of STTM156/157 and STTM165/166 transgenic plants revealed the roles of these miRNAs in plant hormone biosynthesis and activation,secondary metabolism,and ion-channel activity-associated electrophysiology,demonstrating that STTM technology is an effective approach for studying miRNA functions.To facilitate the study and application of STTM transgenic plants and to provide a useful platform for storing and sharing of information about miRNA-regulated gene networks,we have established an online Genome Browser (https://blossom.ffr.mtu.edu/designindex2.php) to display the transcriptomic and miRNAomic changes in STTMinduced miRNA knockdown plants.Ting Peng Mengmeng Qiao Haiping Liu Sachin Teotia Zhanhui Zhang Yafan Zhao Bobo Wang Dongjie Zhao Lina Shi Cui Zhang Brandon Le Kestrel Rogers Chathura Gunasekara Haitang Duan Yiyou Gu Lei Tian Jinfu Nie Jian Qi Fanrong Meng Lan Huang Qinghui Chen Zhenlin Wang Jinshan Tang Xiaoqing Tang Ting Lan Xuemei Chen Hairong Wei Quanzhi Zhao Guiliang Tang 2018Molecular Plant2018,11,11:7
10863 genomes reveal the origin and domestication of chicken显示文摘Despite the substantial role that chickens have played in human societies across the world,both the geographic and temporal origins of their domestication remain controversial.To address this issue,we analyzed 863 genomes from a worldwide sampling of chickens and representatives of all four species of wild jungle fowl and each of the five subspecies of red jungle fowl(RJF).Our study suggests that domestic chickens were initially derived from the RJF subspecies Gallus gallus spadiceus whose present-day distribution is predominantly in southwestern China,northern Thailand and Myanmar.Following their domestication,chickens were translocated across Southeast and South Asia where they interbred locally with both RJF subspecies and other jungle fowl species.In addition,our results show that the White Leghorn chicken breed possesses a mosaic of divergent ancestries inherited from other subspecies of RJF.Despite the strong episodic gene flow from geographically divergent lineages of jungle fowls,our analyses show that domestic chickens undergo genetic adaptations that underlie their unique behavioral,morphological and reproductive traits.Our study provides novel insights into the evolutionary history of domestic chickens and a valuable resource to facilitate ongoing genetic and functional investigations of the world's most numerous domestic animal.Ming-Shan Wang Mukesh Thakur Min-Sheng Peng Yu Jiang Laurent Alain Francois Frantz Ming Li Jin-Jin Zhang Sheng Wang Joris Peters Newton Otieno Otecko Chatmongkon Suwannapoom Xing Guo Zhu-Qing Zheng Ali Esmailizadeh Nalini Yasoda Hirimuthugoda Hidayat Ashari Sri Suladari Moch Syamsul Arifin Zein Szilvia Kusza Saeed Sohrabi Hamed Kharrati-Koopaee Quan-Kuan Shen Lin Zeng Min-Min Yang Ya-Jiang Wu Xing-Yan Yang Xue-Mei Lu Xin-Zheng Jia Qing-Hua Nie Susan Joy Lamont Emiliano Lasagna Simone Ceccobelli Humpita Gamaralalage Thilini Nisanka Gunwardana Thilina Madusanka Senasige Shao-Hong Feng Jing-Fang Si Hao Zhang Jie-Qiong Jin Ming-Li Li Yan-Hu Liu Hong-Man Chen Cheng Ma Shan-Shan Dai Abul Kashem Fazlul Haque Bhuiyan Muhammad Sajjad Khan Gamamada Liyanage Lalanie Pradeepa Silva Thi-Thuy Le Okeyo Ally Mwai Mohamed Nawaz Mohamed Ibrahim Megan Supple Beth Shapiro Olivier Hanotte Guojie Zhang Greger Larson Jian-Lin Han Dong-Dong Wu Ya-Ping Zhang 2020Cell Research2020,30,8:7
11Bioanalysis and Pharmacokinetics of Eight Active Components from Huanglian Jiedu Decoction in Rat Plasma by LC-ESI-MS/MS Method显示文摘Objective To develop a sensitive and rapid liquid chromatography-electrospray ionization-tandem mass spectrometry(LC-ESI-MS/MS) method for the simultaneous determination of wogonin, coptisine, berberine, palmatine, jatrorrhizine, phello-dendrine, magnoflorine, and wogonoside in rat plasma and to evaluate the pharmacokinetic characteristics of Huanglian Jiedu Decoction(HJD). Methods LC separation was performed on an Acquity HSS T3 column(100 mm × 2.1 mm, 1.8 μm) using gradient elution with the mobile phase consisting of acetonitrile and 0.1% formic acid water. The detection was accomplished by using positive electrospray ionization in multiple-reaction monitoring mode. Plasma samples were pretreated by protein precipitation. Results The method showed a good linearity over a wide concentration range(r2 > 0.99). The lower limits of quantification were 0.20 ng/mL for coptisine and phellodendrine, 0.48 ng/mL for berberine, 0.10 ng/mL for jatrorrhizine, 0.32 ng/mL for magnoflorine, 0.30 ng/mL for palmatine, and 4.80 ng/mL for wogonin and wogonoside, respectively. The intra- and inter-day precision of the analytes was less than 12.11%, while the accuracy was between-14.46% and 4.86%. The mean recovery of all the analytes ranged from 93.10% to 110.91%. Conclusion This validated method offers the advantages of high sensitivity. It is successfully applied to evaluating the pharmacokinetic properties of HJD.Cheng-cheng Peng Shu-ping Wang Hui-zi Jin Jian-fei Tao Guo-wei Wang Pan-lei Wei Xu-feng Zhang Le Li Run-hui Liu Wei-dong Zhang 2014Chinese Herbal Medicines2014,6,3:6

13Active digital spoof plasmonics显示文摘Digital coding and digital modulation are the foundation of modern information science.The combination of digital technology with metamaterials provides a powerful scheme for spatial and temporal controls of electromagnetic waves.Such a technique,however,has thus far been limited to the control of free-space light.Its application to plasmonics to shape subwavelength fields still remains elusive.Here,we report the design and experimental realization of a tunable conformal plasmonic metasurface;which is capable of digitally coding and modulating designer surface plasmons at the deep-subwavelength scale.Based on dynamical switching between two discrete dispersion states in a controlled manner;we achieve digital modulations ofboth amplitude and phase of surface waves with nearly 100%modulation depth on a single device.Our study not only introduces a new approach for active dispersion engineering,but also constitutes an important step towards the realization of subwavelength integrated plasmonic circuits.Hao Chi Zhang Tie Jun Cui Yu Luo Jingjing Zhang Jie Xu Pei Hang He Le Peng Zhang 2020National Science Review2020,7,2:5
14Self-propagating high-temperature synthesis of ZrO_2 incorporated Gd_2Ti_2O_7 pyrochlore显示文摘In this research, Zr-doped Gd_2Ti_2O_7 pyrochlores, with the composition of Gd_2(Ti_(1-x)Zr_x)_2O_7, were firstly synthesized by self-propagating high-temperature synthesis plus quick pressing(SHS/QP) using CuO as the oxidant and Ti as the reductant. To improve the radiation resistance of titanate–pyrochlore, up to 35 at% Zr was incorporated to substitute the Ti site of Gd_2Ti_2O_7 pyrochlore(Gd_2(Ti_(0.75)Zr_(0.35))_2O_7). XRD and SEM microstructural characterizations showed the formation of a composite ceramic with the major pyrochlore phase and the minor Cu phase. The generated temperature of samples decreased from 1702to 1011 ℃ with increasing Zr content. The effects of sintering temperature and pressure time on phase composition and microstructure were systematically studied. Besides, the influence of thermal transmission on the whole combustion process was also explored. The pyrochlore-based waste form possessed high bulk density of 6.25 g/cm^3 and Vickers hardness of 10.81 GPa. The MCC-1 leaching test showed the normalized elemental leaching rates(42d) of Cu, Gd, and Zr are 1.27×10^(-2), 1.33×10^(-3), and 8.44×10^(-7)g·m^(-2)·d^(-1), respectively.Le PENG Kuibao ZHANG Zongsheng HE Dan YIN Jiali XUE Chen XU Haibin ZHANG 2018Journal of Advanced Ceramics2018,7,1:5
15Solid-state reaction synthesis and chemical stability studies in Nd-doped zirconolite-rich ceramics显示文摘In this study, Nd-bearing zirconolite-rich ceramics were prepared by solid-state reaction process using CaF_2,ZrO_2, Ti,TiO_2, Fe_2 O_3 and Nd_2O_3 as the raw materials. Neodymium was used as trivalent actinide surrogate and designed to substitute the Ca and Zr sites of zirconolite with general stoichiometry of Ca_(1-x)Zr_(1-x)Nd_(2 x)Ti_2O_7(0≤x≤0.3). Density of Fe-Nd-O sample reaches a maximum value of 4.13 g/cm^2 after being sintered at 1325 ℃ for 42 h. Three major phases, namely zirconolite, perovskite and pseudobrookite, are observed in all these samples. The EDX result shows that Nd_2O_3 can be successfully incorporated into the lattice structure of the prepared zirconolite-rich minerals and replace the Ca sites of zirconolite and perovskite with Fe^(3+) as the charge-compensating ion. Furthermore, the thermal conductivities are all in the range of 1.51-1.67 W/(m·K). The normalized elemental leaching rates of Ca and Nd in the Fe-Nd-0.2 sample keep in low values of 6.20 × 10^(-2) and 4.86 x 10^(-4) g/(m^2·d) after 42 d.Dan Yin Kuibao Zhang Le Peng Zongsheng He Yuan Liu Haibin Zhang Xirui Lu 2018Journal of Rare Earths2018,36,5:5

17Skp2 dictates cell cycle-dependent metabolic oscillation between glycolysis and TCA cycle显示文摘Whether glucose is predomi nantly metabolized via oxidative phosphorylati on or glycolysis differs between quiesce nt versus proliferating cells,iincluding tumor cells.However,how glucose metabolism is coordinated with cell cycle in mammalian cells remains elusive.Here,we report that mammalian cells predominantly utilize the tricarboxylic acid(TCA)cycle in G1 phase,but prefer glycolysis in S phase.Mechanistically,coupling cell cycle with metabolism is largely achieved by timely destruction of IDH1/2,key TCA cycle enzymes,in a Skp2-dependent manner.As such,depleting SKP2 abolishes cell cycle-dependent fluctuation of IDH1 protein abundance,leading to reduced glycolysis in S phase.Furthermore,elevated Skp2 abundance in prostate cancer cells destabilizes IDH1 to favor glycolysis and subsequent tumorigenesis.Therefore,our study reveals a mechanistic link between two cancer hallmarks,aberrant cell cycle and addiction to glycolysis,and provides the underlying mechanism for the coupling of metabolic fluctuation with periodic cell cycle in mammalian cells.Jing Liu Yunhua Peng Le Shi Lixin Wan Hiroyuki Inuzuka Jiangang Long Jianping Guo Jinfang Zhang Min Yuan Shuangxi Zhang Xun Wang Jing Gao Xiangpeng Dai Shozo Furumoto Lijun Jia Pier Paolo Pandolfic John M.Asara William G.Kaelin Jr. Jjankang Liu Wenyi Wei 2021Cell Research2021,31,1:2
18A novel spoof surface plasmon polariton structure to reach ultra-strong field confinements显示文摘Ultrathin corrugated metallic structures have been proved to support spoof surface plasmon polariton (SPP) modes on two-dimension (2D) planar microwave circuits.However,to provide stronger field confinement,larger width of strip is required to load deeper grooves,which is cumbersome in modern large-scale integrated circuits and chips.In this work,a new spoof SPP transmission line (TL) with zigzag grooves is proposed.This new structure can achieve stronger field confinement compared to conventional one with the same strip width.In other words,the proposed spoof SPP TL behaves equivalently to a conventional one with much larger size.Dispersion analysis theoretically indicates the negative correlation between the ability of field confinement and cutoff frequencies of spoof SPP TLs.Numerical simulations indicate that the cutoff frequency of the proposed TL is lower than the conventional one and can be easily modified with the fixed size.Furthermore,two samples of the new and conventional spoof SPP TLs are fabricated for experimental demonstration.Measured S-parameters and field distributions verify the ultra-strong ability of field confinement of the proposed spoof SPP TL.Hence,this novel spoof SPP structure with ultra-strong field confinement may find wide applications in microwave and terahertz engineering.Pei Hang He Hao Chi Zhang Xinxin Gao Ling Yun Niu Wen Xuan Tang Jiayuan Lu Le Peng Zhang Tie Jun Cui 2019Opto-Electronic Advances2019,2,6:2

20Biomarkers of aging显示文摘Aging biomarkers are a combination of biological parameters to(i)assess age-related changes,(ii)track the physiological aging process,and(iii)predict the transition into a pathological status.Although a broad spectrum of aging biomarkers has been developed,their potential uses and limitations remain poorly characterized.An immediate goal of biomarkers is to help us answer the following three fundamental questions in aging research:How old are we?Why do we get old?And how can we age slower?This review aims to address this need.Here,we summarize our current knowledge of biomarkers developed for cellular,organ,and organismal levels of aging,comprising six pillars:physiological characteristics,medical imaging,histological features,cellular alterations,molecular changes,and secretory factors.To fulfill all these requisites,we propose that aging biomarkers should qualify for being specific,systemic,and clinically relevant.Aging Biomarker Consortium Hainan Bao Jiani Cao Mengting Chen Min Chen Wei Chen Xiao Chen Yanhao Chen Yu Chen Yutian Chen Zhiyang Chen Jagadish K Chhetri Yingjie Ding Junlin Feng Jun Guo Mengmeng Guo Chuting He Yujuan Jia Haiping Jiang Ying Jing Dingfeng Li Jiaming Li Jingyi Li Qinhao Liang Rui Liang Feng Liu Xiaoqian Liu Zuojun Liu Oscar Junhong Luo Jianwei Lv Jingyi Ma Kehang Mao Jiawei Nie Xinhua Qiao Xinpei Sun Xiaoqiang Tang Jianfang Wang Qiaoran Wang Siyuan Wang Xuan Wang Yaning Wang Yuhan Wang Rimo Wu Kai Xia Fu-Hui Xiao Lingyan Xu Yingying Xu Haoteng Yan Liang Yang Ruici Yang Yuanxin Yang Yilin Ying Le Zhang Weiwei Zhang Wenwan Zhang Xing Zhang Zhuo Zhang Min Zhou Rui Zhou Qingchen Zhu Zhengmao Zhu Feng Cao Zhongwei Cao Piu Chan Chang Chen Guobing Chen Hou-Zao Chen Jun Chen Weimin Ci Bi-Sen Ding Qiurong Ding Feng Gao Jing-Dong JHan Kai Huang Zhenyu Ju Qing-Peng Kong Ji Li Jian Li Xin Li Baohua Liu Feng Liu Lin Liu Qiang Liu Qiang Liu Xingguo Liu Yong Liu Xianghang Luo Shuai Ma Xinran Ma Zhiyong Mao Jing Nie Yaojin Peng Jing Qu Jie Ren Ruibao Ren Moshi Song Zhou Songyang Yi Eve Sun Yu Sun Mei Tian Shusen Wang Si Wang Xia Wang Xiaoning Wang Yan-Jiang Wang Yunfang Wang Catherine CL Wong Andy Peng Xiang Yichuan Xiao Zhengwei Xie Daichao Xu Jing Ye Rui Yue Cuntai Zhang Hongbo Zhang Liang Zhang Weiqi Zhang Yong Zhang Yun-Wu Zhang Zhuohua Zhang Tongbiao Zhao Yuzheng Zhao Dahai Zhu Weiguo Zou Gang Pei Guang-Hui Liu 2023Science China(Life Sciences)2023,66,5:2
