| 1 | Eleven COVID-19 Outbreaks with Local Transmissions Caused by the Imported SARS-CoV-2 Delta VOC-China,July-August,2021显示文摘Starting from December 2019,Wuhan,China,encountered the first outbreak of coronavirus disease 2019(COVID-19)(1-2).The epidemic was successfully suppressed by strict containment so that the number of infected people was reduced to 0 on April 8,2020(3–4).After that,China experienced roughly 3 dozen outbreaks with local transmission caused by imported severe acute respiratory syndrome coronavirus 2(SARS-CoV-2). | Lei Zhou Kai Nie Hongting Zhao Xiang Zhao Bixiong Ye Ji Wang Cao Chen Hong Wang Jiangli Di Jinsong Li Chao Li Zhixiao Chen Ruiqi Ren Peihua Niu Hui Chen Tao Chen Yali Wang Lili Li Bingxue Han Ruhan A Si Chen Dan Li Dan Li Chunxia Jin Xin Zhang Jiangmei Liu Chunyu Xu Yecheng Yao Yenan Feng Zhili Li Bike Zhang Yang Song Peter Hao Yanping Zhang Hao Li Qun Li George F.Gao Guoqing Shi Wenbo Xu | 2021 | China CDC weekly2021，3，41： | 13 |
| 2 | Fabrication of highly efficient heterostructured Ag-CeO2/g-C3N4 hybrid photocatalyst with enhanced visible-light photocatalytic activity显示文摘On the basis of hydrothermal synthesis of Ag-CeO2 microspheres,Ag-CeO2/g-C3N4 composite photocatalyst with heterostructure was prepared by simple solvent evaporation of Ag-CeO2 and g-C3N4.To characterize the composition,structure,morphology and light absorption properties of the as-prepared Ag-CeO2/g-C3N4 composites,XRD,FTIR XPS,SEM,TEM,PL,BET and UV-vis DRS were used,respectively.The as-prepared photocatalyst was subjected to photocatalytic degradation of pollutants,and the prepared composite material has excellent photocatalytic activity for photodegradation of methylene blue(MB).The research shows that the photocatalytic properties of Ag-CeO2/g-C3N4 composites were related to the mass ratio of Ag-CeO2 microspheres and g-C3N4 nanosheets.When the ratio of Ag-CeO2 microspheres:g-C3N4 is 1:5,the composites have the highest photocatalytic activity,which was 9.6 and 3.3 times that of single Ag-CeO2 and g-C3N4,respectively.The improvement of photocatalytic activity is attributed to the heterostructure between the composite materials and the addition of noble metal silver,and the degradation of methylene blue by the visible light irradiation material is greatly improved.Finally,an attempt was made to analyze the principle of photocatalytic degradation of pollutants in prepared materials. | Chengbao Liu Dongxing Mao Jian Pan Junchao Qian Wenya Zhang Feng Chen Zhigang Chen Yenan Song | 2019 | Journal of Rare Earths2019，37，12： | 7 |
| 3 | The DNMT1-PAS1-PH20 axis drives breast cancer growth and metastasis显示文摘PH20 is a member of the human hyaluronidase family that degrades hyaluronan in the extracellular matrix and controls tumor progression.Inhibition of DNA methyltransferases(DNMTs)leads to elevated hyaluronan levels;however,whether DNMT inhibitors control PH20 remains unclear.Here,we report that the DNMT1 inhibitor,decitabine,suppresses PH20 expression by activating the long non-coding RNA PHACTR2-AS1(PAS1).PAS1 forms a tripartite complex with the RNA-binding protein vigilin and histone methyltransferase SUV39H1.The interaction between PAS1 and vigilin maintains the stability of PAS1.Meanwhile,PAS1 recruits SUV39H1 to trigger the H3K9 methylation of PH20,resulting in its silencing.Functionally,PAS1 inhibits breast cancer growth and metastasis,at least partially,by suppressing PH20.Combination therapy of decitabine and PAS1-30nt-RNA,which directly binds to SUV39H1,effectively blocked breast cancer growth and metastasis in mice.Taken together,DNMT1,PAS1,and PH20 comprise a regulatory axis to control breast cancer growth and metastasis.These findings reveal that the DNMT1-PAS1-PH20 axis is a potential therapeutic target for breast cancer. | Yenan Fu Xi Zhang Xiao Liu Peng Wang Wenhui Chu Wei Zhao Yunling Wang Guangbiao Zhou Yu Yu Hongquan Zhang | 2022 | Signal Transduction and Targeted Therapy2022，7，4： | 2 |
| 4 | Derivation of totipotent-like stem cells with blastocyst-like structure forming potential显示文摘It is challenging to derive totipotent stem cells in vitro that functionally and molecularly resemble cells from totipotent embryos.Here,we report that a chemical cocktail enables the derivation of totipotent-like stem cells,designated as totipotent potential stem(TPS)cells,from 2-cell mouse embryos and extended pluripotent stem cells,and that these TPS cells can be stably maintained long term in vitro.TPS cells shared features with 2-cell mouse embryos in terms of totipotency markers,transcriptome,chromatin accessibility and DNA methylation patterns.In vivo chimera formation assays show that these cells have embryonic and extraembryonic developmental potentials at the single-cell level.Moreover,TPS cells can be induced into blastocyst-like structures resembling preimplantation mouse blastocysts.Mechanistically,inhibition of HDAC1/2 and DOT1L activity and activation of RARγsignaling are important for inducing and maintaining totipotent features of TPS cells.Our study opens up a new path toward fully capturing totipotent stem cells in vitro. | Yaxing Xu Jingru Zhao Yixuan Ren Xuyang Wang Yulin Lyu Bingqing Xie Yiming Sun Xiandun Yuan Haiyin Liu Weifeng Yang Yenan Fu Yu Yu Yinan Liu Rong Mu Cheng Li Jun Xu Hongkui Deng | 2022 | Cell Research2022，32，6： | 1 |

| 6 | Occurrence and Damage Regularity of Spodoptera litura in Broccoli显示文摘[Objective] The paper was to explore the occurrence and damage regularity of Spodoptera litura in broccoli,and to reveal the annual movement regularity and seasonal fluctuation regularity of S.litura population.[Method] The monitoring data of sexual attractants at fixed points for 11 consecutive years were summarized and analyzed.[Result] The large occurrence frequency of S.litura in Taizhou was 36.4%;the annual movement showed a downward-opening parabolic form,and the movement trajectory was N =-18.416 t^(2)+182.51 t +179.71,t ={1,2,3,…,n}(n =11;r =0.691 7*).The seasonal fluctuation showed a trend of peak oscillation attenuation curve,and the total moth quantity gradually decreased from sowing to heading stage.The functional model of average daily quantity was m=0.000 2 d^(2)-0.067 5 d+6.797 3,d={1,2,3,…,n}(n =186,r=0.955 2**).Air temperature was the main external factor affecting the seasonal variation of quantity,and there was a significant correlation be-tween the number of ten-day moth trapping quantity and ten-day average temperature:M =0.243 T^(2)-6.935 1 T +46.681(n =108,r =0.560 2**)or M=2.734 4 T-35.446(n=108,r=0.500 3**).Therefore,the moth quantity in the field increased with the increase of ten-day average temperature,and the period from July to September with high temperature and less rainfall was the peak occurrence period of S.litura.[Conclusion] These models can be used to improve the prediction and early warning levels of S.litura in broccoli,and has good guiding significance for decision-making and prevention. | Weiming Liu Enguo Wang Yenan Liu | 2021 | Plant Diseases and Pests2021，12，4： | 0 |
| 7 | Research on Chemical Prevention and Control against Stem Base Rot of Sweet Potato显示文摘[Objective]The paper was to effectively control stem base rot of sweet potato.[Method]Chemical prevention and control test against stem base rot of sweet potato were conducted for consecutive three years from 2016 to 2018.[Result]The use of carbendazim or carbendazim+mancozeb,and carbendazim+embamycin had significant control effect on stem base rot of sweet potato.However,the applied concentration should be higher than the recommended concentration.Especially the concentration of 50%carbendazim WP should be no more than 300 times,and the prevention and control effect of 100 times dilution would be better.[Conclusion]The types and concentrations of prevention and control agents are determined in the test,which will provide certain basis for chemical prevention and control against stem base rot of sweet potato. | Liu Yenan Liu Weiming He Xianbiao Huang Lifei | 2021 | Plant Diseases and Pests2021，12，1： | 0 |
