| 1 | Nondestructive 3D Image Analysis Pipeline to Extract Rice Grain Traits Using X-Ray Computed Tomography显示文摘The traits of rice panicles play important roles in yield assessment,variety classification,rice breeding,and cultivation management.Most traditional grain phenotyping methods require threshing and thus are time-consuming and labor-intensive;moreover,these methods cannot obtain 3D grain traits.In this work,based on X-ray computed tomography,we proposed an image analysis method to extract twenty-two 3D grain traits.After 104 samples were tested,the R^(2) values between the extracted and manual measurements of the grain number and grain length were 0.980 and 0.960,respectively.We also found a high correlation between the total grain volume and weight.In addition,the extracted 3D grain traits were used to classify the rice varieties,and the support vector machine classifier had a higher recognition accuracy than the stepwise discriminant analysis and random forest classifiers.In conclusion,we developed a 3D image analysis pipeline to extract rice grain traits using X-ray computed tomography that can provide more 3D grain information and could benefit future research on rice functional genomics and rice breeding. | Weijuan Hu Can Zhang Yuqiang Jiang Chenglong Huang Qian Liu Lizhong Xiong Wanneng Yang Fan Chen | 2020 | Plant Phenomics2020，2，1： | 6 |

| 3 | 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 |
| 4 | High-throughput screening identifies established drugs as SARS-CoV-2 PLpro inhibitors显示文摘A new coronavirus(SARS-CoV-2)has been identified as the etiologic agent for the COVID-19 outbreak.Currently,effective treatment options remain very limited for this disease;therefore,there is an urgent need to identify new anti-COVID-19 agents.In this study,we screened over 6,000 compounds that included approved drugs,drug candidates in clinical trials,and pharmacologically active compounds to identify leads that target the SARS-CoV-2 papain-like protease(PLpro).Together with main protease(Mpro),PLpro is responsible for processing the viral replicase polyprotein into functional units.There-fore,it is an attractive target for antiviral drug develop-ment.Here we discovered four compounds,YM155,cryptotanshinone,tanshinone I and GRL0617 that inhibit SARS-CoV-2 PLpro with IC50 values ranging from 1.39 to 5.63 pmol/L.These compounds also exhibit strong antiviral activities in cell-based assays.YM155,an anti-cancer drug candidate in clinical trials,has the most potent antiviral activity with an EC50 value of 170 nmol/L.In addition,we have determined the crystal structures of this enzyme and its complex with YM155,revealing a unique binding mode.YM155 simultaneously targets three'hot'spots on PLpro,including the substrate-binding pocket,the interferon stimulating gene product 15(ISG15)binding site and zinc finger motif.Our results demonstrate the efficacy of this screening and repur-posing strategy,which has led to the discovery of new drug leads with clinical potential for COVID-19 treatments. | Yao Zhao Xiaoyu Du Yinkai Duan Xiaoyan Pan Yifang Sun Tian You Lin Han Zhenming Jin Weijuan Shang Jing Yu Hangtian Guo Qianying Liu Yan Wu Chao Peng Jun Wang Chenghao Zhu Xiuna Yang Kailin Yang Ying Lei Luke W.Guddat Wenqing Xu Gengfu Xiao Lei Sun Leike Zhang Zihe Rao Haitao Yang | 2021 | Protein & Cell2021，12，11： | 4 |
| 5 | Epidemiological and Virological Surveillance of Seasonal Influenza Viruses—China,2020–2021显示文摘Introduction:During the coronavirus disease 2019(COVID-19)pandemic,the circulation of seasonal influenza virus declined globally and remained below previous seasonal levels.We analyzed the results of the epidemiology,antigenic,and genetic characteristics,and antiviral susceptibilities of seasonal influenza viruses isolated from the mainland of China during October 5,2020 through September 5,2021,to better assess the risk of influenza during subsequent influenza season in 2021–2022.Methods:Positive rates of influenza virus detection during this period were based on real-time polymerase chain reaction(PCR)detection by the Chinese National Influenza Surveillance Network laboratories,and isolated viruses from influenza positive samples were submitted to the Chinese National Influenza Center.Antigenic analyses for influenza viruses were conducted using the hemagglutination inhibition assay.Next-generation sequencing was used for genetic analyses.Viruses were tested for resistance to antiviral medications using a phenotypic assay and next-generation sequencing.Results:In southern China,the influenza positivity rate was elevated especially after March 2021 and was higher than the same period the previous year with the COVID-19 pandemic.In northern China,influenza positive rate peaked at Week 18 in 2021 and has declined since then.Nearly all isolated viruses were B/Victoria lineage viruses during the study period,and 37.3%of these viruses are antigenically similar to the reference viruses representing the vaccine components for the 2020–2021 and 2021–2022 Northern Hemisphere influenza season.All seasonal influenza viruses were susceptible to neuraminidase inhibitors and endonuclease inhibitors.Conclusions:Influenza activity has gradually increased in the mainland of China in 2021,although the intensity of activity is still lower than before the COVID-19 pandemic.The diversity of circulating influenza types/subtypes decreased,with the vast majority being B/Victoria lineage viruses.The surveillance data from this study suggest that we should strengthen influenza surveillance during the upcoming traditional influenza season.It also provided evidence for vaccine recommendations and prevention and control of influenza and clinical use of antiviral drugs. | Weijuan Huang Xiyan Li Minju Tan Yanhui Cheng Tao Chen Hejiang Wei Xiaoxu Zeng Yiran Xie Jia Liu Ning Xiao Lei Yang Dayan Wang | 2021 | China CDC weekly2021，3，44： | 4 |
| 6 | Effect of particle size and oxygen content on ignition and combustion of aluminum particles显示文摘Particle size and oxygen content are two of the key factors that affect the ignition and combustion properties of aluminum particles. In this study, a laser ignition experimental system and flame test system were built to analyze the ignition and combustion characteristics and the flame morphology of aluminum particles. A thermobalance system was used to analyze the thermal oxidation characteristics. In addition, the microstructure of aluminum was analyzed by scanning electron microscopy. It was found that the oxidized products were some of the gas phase products agglomerated. Smaller particle size samples showed better combustion characteristics. The combustion intensity, self-sustaining combustion time and the burn-off rate showed a rising trend with the decrease in the particle size. Increasing the oxygen content in the atmosphere could improve the ignition and combustion characteristics of the samples. Four distinct stages were observed in the process of ignition and combustion. Small particle size samples had a larger flame height and luminance, and the self-sustaining combustion time was much longer.Three distinct stages were observed during the thermal oxidation process. The degree of oxidation for small-sized samples was significantly higher than that for the larger particle size samples.Moreover, it was observed that the higher the oxygen content, the higher the degree of oxidation was. | Yu'nan ZHOU Jianzhong LIU Daolun LIANG Wei SHI Weijuan YANG Junhu ZHOU | 2017 | Chinese Journal of Aeronautics2017，30，6： | 4 |
| 7 | Preparation of hapten-specific monoclonal antibody for cadmium and its ELISA application to aqueous samples显示文摘High-affinity and specific monoclonal antibodies against cadmium-ethylene diamine tetraacetic acid(EDTA)complex have been produced using the hybridoma technique.A hapten was synthesized and characterized by Fourier Transform Infrared Spectroscopy(FT-IR)and UVVis.Competitive enzyme-linked immunosorbent assay(ELISA)for quantitative detection of cadmium in aqueous sample was developed.The monoclonal antibody with high level of binding affinity for Cd-IEDTA-BSA and high specificity for soluble Cd-EDTA complex showed less than 0.99%cross-reactivity with other 11 metals.The limit of detection was 0.10μg·L^(-1),and the effective linear range was 10^(-1)-10^(3)μg·L^(-1).The intra-and inter-assay coefficient variations were 1.5%-6.3%and 3.2%-7.4%,respectively.The spike recovery in different water samples were between 98.5%and 110.3%.The detection limit of this assay was well below the allowable concentration of cadmium(3μg·L^(-1)),and the working range was wider than that of other methods which showed the range of 2.19-86.38 and 0-10^(3)μg·L^(-1).The competitive ELISA established in this paper was sensitive and accurate in the screening of cadmium in aqueous samples.The results will lay a solid foundation for construction of an immunoassay kit for cadmium. | Huan HE Bo TANG Cheng SUN Shaogui YANG Weijuan ZHENG Zichun HUA | 2011 | Frontiers of Environmental Science & Engineering2011，5，3： | 4 |
| 8 | Fluorine in drinking water and urine in the urban and rural areas of northwestern China——Its determination by a fluoride ion selective electrode显示文摘In this study, the author determined fluorine in drinking water and urine of residents who are divided into four age groups (5, 12, 35-44, 65-74 aged), living in Huangling City, Shaanxi Province and at 6 villages of Qin'an County, Gansu Province, P.R.China. Some residents are living in fluorine exposure areas. A total of 929 residents (463 females and 466 males) involved in the study were selected from 7 tap water systems. Drinking water samples were collected from each area and analyzed using the fluoride ion-selective method. No positive correlation relationship was found between fluorine concentrations in urine and those in drinking water in the area where the fluorine concentrations of drinking water are within the range of 1-2 mg/L. The fluorine absorbed by resistents of different ages is different in amount. With the same concentrations of fluorine in drinking water, more fluorine would be absorbed by young residents than old residents. No difference can be seen in absorption amount of fluorine among different genders. | WANG Binbin ZHENG Baoshan LIAN Weijuan YANG Lan HUANG Ruizhe RUAN Jianping | 2009 | Chinese Journal Of Geochemistry2009，28，2： | 2 |
| 9 | Neutron activation analysis and Mossbauer spectroscopy research on coloring mechanism of Chinese Ru porcelain显示文摘The characteristic spectrum and its main wavelength of Ru porcelain glaze are measured by color difference instrument to determine the relations between glaze color and its main wavelength. The content of the 30 coloring elements in Ru porcelain is determined by neutron activation analysis (NAA), which showed that iron is the major coloring element. Mossbauer spectroscopy analysis shows that the iron element in the glaze exists in the form of structural iron (Fe2+, Fe3+). The quantitative relationship between the main wavelength of glaze in various colors and the relative content of structural iron (Fe2+/Fe3+) is determined. Thus the coloring mechanism of Ru porcelain is investigated entirely. | LI Rongwu YANG Lei LI Guoxia ZHAO Weijuan GAO Zhengyao XIE Jianzhong CHEN Jin ZHANG Bin SUN Xinmin FENG Songlin JIA Xiuqin HAN Song HUANG Zhongxiang | 2002 | Chinese Science Bulletin2002，47，14： | 2 |
| 10 | Characterization of Influenza Viruses-China, 2019−2020显示文摘Introduction:Influenza surveillance is necessary for detection of emerging variants of influenza viruses and determining their epidemiological and clinical significance.Vaccination and antiviral drugs remain the most useful ways to protect against seasonal influenza and its potentially severe consequences.This study describes the epidemiology,antigenic and genetic characteristics,and antiviral susceptibilities of influenza viruses isolated from the mainland of China during the April 1,2019 through October 4,2020.Methods:All viruses analyzed were isolated and submitted by Chinese National Influenza Surveillance Network laboratories.The Chinese National Influenza Center performed antigenic analysis,sequencing,and antiviral resistance testing after propagation of the viruses.Antigenic characterizations were determined by hemagglutinin inhibition assay;next-generation sequencing was used for genetic analyses;phenotypic assay and next-generation sequencing were used for determining antiviral resistance.Results:The influenza positivity rate declined significantly starting in late January 2020 and has remained low.There was no summer influenza peak season in south China.Influenza A(H3N2)and B/Victoria lineage viruses were the dominant subtype/lineage during April 1,2019 through October 4,2020.The majority of influenza viruses were antigenically and genetically similar to reference viruses representing components of vaccines for the 2020–2021 northern hemisphere influenza season.Nearly all seasonal influenza viruses were susceptible to oseltamivir and zanamivir.Conclusions and Implications for Public Health Practice:Since the outbreak of COVID-19,the influenza positivity rate declined with implementation of strong COVID-19 control measures.The majority of circulating viruses are well matched with the current 2020–2021 northern hemisphere influenza vaccine viruses.Circulating seasonal influenza viruses were sensitive to neuraminidase inhibitors and Baloxavir marboxil.This study provided evidence for World Health Organization(WHO)recommendations for vaccine viruses,for prevention and control of influenza,and for clinical use of antiviral medications. | Weijuan Huang Yanhui Cheng Tao Chen Xiyan Li Minju Tan Hejiang Wei Xiaoxu Zeng Yiran Xie Jia Liu Ning Xiao Lei Yang Dayan Wang | 2020 | China CDC weekly2020，2，44： | 2 |

| 13 | Mutations associated with egg adaptation of influenza A(H1N1)pdm09 virus in laboratory based surveillance in China, 2009–2016显示文摘Mutations of influenza virus associated with adaptation occurring during passage in embryonated chicken eggs could result in antigenic change or reduced vaccine effectiveness.In this study,we investigated the mutations of influenza A(H1N1)pdm09 egg isolates from the Chinese National Influenza Surveillance Network between 2009 and 2016.Thirteen mutations were identified in the hemagglutinin(HA)protein from viruses passaged in eggs,in comparing to those in cells.After scanning public database,four mutations,D127E,L191I,D222G/N and Q223R in HA1,which may alter the receptor-binding specificity,were observed frequently.Although the A(H1N1)pdm09 virus has evolved in human for nearly ten years,most egg-cultured viruses acquired one or more further mutations.Using the egg isolates for influenza surveillance requires extra caution because of these selected mutations,and their impacts on antigenicity and receptor-binding property need further evaluation.Currently,most of the influenza vaccines are produced using egg isolates,particularly in China.Thus,there is an urge to promote the establishment of an alternative influenza vaccine production platform. | Lei Yang Yanhui Cheng Xiang Zhao Hejiang Wei Minju Tan Xiyan Li Wenfei Zhu Weijuan Huang Wenbing Chen Jia Liu Zi Li Yuelong Shu Dayan Wang | 2019 | Biosafety and Health2019，1，1： | 1 |

| 20 | Angiopoietin-like 4 promotes epidermal stem cell proliferation and migration and contributes to cutaneous wound re-epithelialization显示文摘Proliferation and migration of epidermal stem cells(EpSCs)are essential for epithelialization during skin wound healing.Angiopoietin-like 4(ANGPTL4)has been reported to play an important role in wound healing,but the mechanisms involved are not fully understood.Here,we investigate the contribution of ANGPTL4 to full-thickness wound re-epithelialization and the underlying mechanisms using Angptl4-knockout mice.Immunohistochemical staining reveals that ANGPTL4 is significantly upregulated in the basal layer cells of the epidermis around the wound during cutaneous wound healing.ANGPTL4 deficiency impairs wound healing.H&E staining shows that ANGPTL4 deficiency significantly reduces the thickness,length and area of the regenerated epidermis postwounding.Immunohistochemical staining for markers of EpSCs(α6 integrin andβ1 integrin)and cell proliferation(PCNA)shows that the number and proliferation of EpSCs in the basal layer of the epidermis are reduced in ANGPTL4-deficient mice.In vitro studies show that ANGPTL4 deficiency impedes EpSC proliferation,causes cell cycle arrest at the G1 phase and reduces the expressions of cyclins D1 and A2,which can be reversed by ANGPTL4 overexpression.ANGPTL4 deletion suppresses EpSC migration,which is also rescued by ANGPTL4 overexpression.Overexpression of ANGPTL4 in EpSCs accelerates cell proliferation and migration.Collectively,our results indicate that ANGPTL4 promotes EpSC proliferation by upregulating cyclins D1 and A2 expressions and accelerating the cell cycle transition from G1 to S phase and that ANGPTL4 promotes skin wound re-epithelialization by stimulating EpSC proliferation and migration.Our study reveals a novel mechanism underlying EpSC activation and re-epithelialization during cutaneous wound healing. | Yuan Yang Chenghao Yu Yingying Le Weijuan Gong Jihui Ju Guangliang Zhang Pengxiang Ji Rui Zuo Zhe Liu Ping Zhang Ruixing Hou Yi Fu | 2023 | Acta Biochimica et Biophysica Sinica2023，55，8： | 0 |
