1Engineering Broad-Spectrum Bacterial Blight Resistance by Simultaneously Disrupting Variable TALE-Binding Elements of Multiple Susceptibility Genes in Rice显示文摘Xanthomonas oryzae pv.oryzae(Xoo),the causal agent of bacterial blight of rice,employs the transcription activator-like effectors(TALEs)to induce the expression of the OsSWEET family of putative sugar transporter genes,which function in conferring disease susceptibility(S)in rice plants.To engineer broadspectrum bacterial blight resistance,we used CRISPR/Cas9-mediated gene editing to disrupt the TALEbinding elements(EBEs)of two S genes,OsSWEETH and OsSWEET14,in rice cv.Kitaake,which harbors the recessive resistance allele of Xa25/OsSWEET13.The engineered rice line MS14K exhibited broadspectrum resistance to most Xoo strains with a few exceptions,suggesting that the compatible strains may contain new TALEs.We identified two PthXo2-like TALEs,Tal5LN18 and Tal7PX061,as major virulence factors in the compatible Xoo strains LN18 and PX061,respectively,and found that Xoo encodes at least five types of PthXo2-like effectors.Given that PthXo2/PthXo2.1 target OsSlVEETf3 for transcriptional activation,the genomes of 3000 rice varieties were analyzed for EBE variationsin the OsSWEET13 promoter,and 10Xa25-like haplotypes were identified.We found that Tal5LN18 and Tal7PX〇6i bind slightly different EBE sequences in the OsSWEET13 promoter to activate its expression.CRISPR/Cas9 technology was then used to generate InDels in the EBE of the OsSWEET13 promoter in MS14K to creat a new germplasm with three edited OsSWEET EBEs and broad-spectrum resistance against all Xoo strains tested.Collectively,our findings illustrate how to disarm TALE-S co-evolved loci to generate broad-spectrum resistance through the loss of effector-triggered susceptibility in plants.Zhengyin Xu Xiameng Xu Qiang Gong Ziyang Li Ying Li Sai Wang Yangyang Yang Wenxiu Ma Longyu Liu Bo Zhu Lifang Zou Gongyou Chen 2019Molecular Plant2019,12,11:29

4Disease profile and plasma neutralizing activity of postvaccination Omicron BA.1 infection in Tianjin,China:a retrospective study显示文摘Dear Editor,SARS-CoV-2 Omicron variant BA.1 first emerged on the Chinese mainland on January 8,2022,in Tianjin and caused a large wave of infections.1 Four rounds of mass testing of its~14 million residents were launched on January 9,12,15,and 20,respectively.As of February 7,2022,a total of 430 individuals were tested positive for Omicron BA.1,with no new infections detected for the following 16 days.In the Chinese mainland,the most delivered vaccines are inactivated vaccines.As of January 8,2022,up to 93.2%of Tianjin’s residents had been vaccinated with at least one dose.2 We investigated the protection conferred by vaccination against Omicron BA.1 by examining the breakthrough infections among vaccinees as compared with unvaccinated cases.Our study population comprised all 430 cases during the outbreak of Omicron BA.1 in Tianjin.Hong Zheng Yunlong Cao Xiaosu Chen Fengmei Wang Ye Hu Weiliang Song Yangyang Chai Qingqing Gu Yansong Shi Yingmei Feng Shuxun Liu Yan Xie Xiaoliang Sunney Xie Wentao Jiang Zhongyang Shen 2022Cell Research2022,32,8:12
5Endometrial membrane organoids from human embryonic stem cell combined with the 3D Matrigel for endometrium regeneration in asherman syndrome显示文摘Asherman’s syndrome(AS),a leading cause of uterine infertility worldwide,is characterized by scarring of the uterine surfaces lacking endometrial epithelial cells,which prevents endometrial regeneration.Current research on cell therapy for AS focuses on mesenchymal and adult stem cells from the endometrium.However,insufficient number,lack of purity,and rapid senescence of endometrial epithelial progenitor cells(EEPCs)during experimental processes restrict their use in cell therapies.In this study,we induced human embryonic stem cells-9(H9-ESC)into EEPCs by optimizing the induction factors from the definitive endoderm.EEPCs,which act as endometrial epithelial cells,accompanied by human endometrial stromal cells provide a niche environment for the development of endometrial membrane organoids(EMOs)in an in vitro 3D culture model.To investigate the function of EMOs,we transplanted tissue-engineered constructs with EMOs into an in vivo rat AS model.The implantation of EMOs into the damaged endometrium facilitates endometrial regeneration and angiogenesis.Implanting EMOs developed from human embryonic stem cells into the endometrium might prove useful for“endometrial re-engineering”in the treatment of Asherman’s syndrome.Xiuxiu Jiang Xingmiao Li Xiangwei Fei Jiajie Shen Jianhua Chen Meijun Guo Yangyang Li 2021Bioactive Materials2021,6,11:11
6Q-switched and mode-locked Er-doped fiber laser using PtSe2 as a saturable absorber显示文摘We report a passively Q-switched and mode-locked erbium-doped fiber laser(EDFL) based on PtSe_2, a new two-dimensional material, as a saturable absorber(SA). Self-started Q-switching at 1560 nm in the EDFL was achieved at a threshold pump power of 65 mW, and at the maximum pump power of 450 m W, the maximum single Q-switched pulse energy is 143.2 n J. Due to the polarization-dependent characteristics of the PtSe_2-based SA, the laser can be switched from the Q-switched state to the mode-locked state by adjusting the polarization state. A mode-locked pulse train with a repetition rate of 23.3 MHz and a pulse width of 1.02 ps can be generated when the pump power increases to about 80 m W, and the stable mode-locked state is maintained until the pump power reaches its maximum 450 m W. The maximum single mode-locked pulse energy is0.53 nJ. This is the first time to our knowledge that successful generation of stable Q-switched and mode-locked pulses in an Er-doped fiber laser has been obtained by using PtSe_2 as a saturable absorber.KANG ZHANG MING FENG YANGYANG REN FANG LIu XINGSHUO CHEN JIE YANG XIAO-QING VAN FENG SONG JIANGUO TIAN 2018Photonics Research2018,6,9:10
7In vivo self-assembled small RNAs as a new generation of RNAi therapeutics显示文摘RNAi therapy has undergone two stages of development,direct injection of synthetic siRNAs and delivery with artificial vehicles or conjugated ligands;both have not solved the problem of efficient in vivo siRNA delivery.Here,we present a proof-of-principle strategy that reprogrammes host liver with genetic circuits to direct the synthesis and self-assembly of siRNAs into secretory exosomes and facilitate the in vivo delivery of siRNAs through circulating exosomes.By combination of different genetic circuit modules,in vivo assembled siRNAs are systematically distributed to multiple tissues or targeted to specific tissues(e.g.,brain),inducing potent target gene silencing in these tissues.The therapeutic value of our strategy is demonstrated by programmed silencing of critical targets associated with various diseases,including EGFR/KRAS in lung cancer,EGFR/TNC in glioblastoma and PTP1B in obesity.Overall,our strategy represents a next generation RNAi therapeutics,which makes RNAi therapy feasible.Zheng Fu Xiang Zhang Xinyan Zhou Uzair Ur-Rehman Mengchao Yu Hongwei Liang Hongyuan Guo Xu Guo Yan Kong Yuanyuan Su Yangyang Ye Xiuting Hu Wei Cheng Jinrong Wu Yanbo Wang Yayun Gu Sheng-feng Lu Dianqing Wu Ke Zen Jing Li Chao Yan Chen-Yu Zhang Xi Chen 2021Cell Research2021,31,6:10
8Defects enriched hollow porous Co-N-doped carbons embedded with ultrafine CoFe/Co nanoparticles as bifunctional oxygen electrocatalyst for rechargeable flexible solid zinc-air batteries显示文摘The construction and design of highly efficient and inexpensive bifunctional oxygen electrocatalysts substitute for noble-metal-based catalysts is highly desirable for the development of rechargeable Zn-air battery(ZAB).In this work,a bifunctional oxygen electrocatalysts of based on ultrafine CoFe alloy(4-5 nm)dispersed in defects enriched hollow porous Co-N-doped carbons,made by annealing SiO2 coated zeolitic imidazolate framework-67(ZIF-67)encapsulated Fe ions.The hollow porous structure not only exposed the active sites inside ZIF-67,but also provided efficient charge and mass transfer.The strong synergetic coupling among high-density CoFe alloys and Co-N_(x) sites in Co,N-doped carbon species ensures high oxygen reduction reaction(ORR)and oxygen evolution reaction(OER)activity.First-principles simulations reveal that the synergistic promotion effect between CoFe alloy and Co-N site effectively reduced the formation energy of from O^(*)to OH^(*).The optimized CoFe-Co@PNC exhibits outstanding electrocatalytic stability and activity with the overpotential of only 320 mV for OER at 10 mA·cm^(−2) and the half-wave potential of 0.887 V for ORR,outperforming that of most recent reported bifunctional electrocatalysts.A rechargeable ZAB constructed with CoFe-Co@PNC as the air cathode displays long-term cyclability for over 200 h and high power density(152.8 mW·cm^(−2)).Flexible solid-state ZAB with our CoFe-Co@PNC as the air cathode possesses a high open circuit potential(OCP)up to 1.46 V as well as good bending flexibility.This universal structure design provides an attractive and instructive model for the application of nanomaterials derived from MOF in the field of sustainable flexible energy applications device.Zhao Lei Yangyang Tan Zeyi Zhang Wei Wu Niancai Cheng Runzhe Chen Shichun Mu Xueliang Sun 2021Nano Research2021,14,3:9
9Salvianolic acid A alleviates renal injury in systemic lupus erythematosus induced by pristane in BALB/c mice显示文摘The purpose of this study was to investigate the effects of salvianolic acid A(SAA) in systemic lupus erythematosus(SLE) induced by pristane in BALB/c mice.Lupus mice were established by confirming elevated levels of autoantibodies and IL-6 after intraperitoneal injection of pristane.Mice were then treated with daily oral doses of SAA for 5 months in parallel with mice treated with prednisone and aspirin as positive controls.The levels of autoantibodies were monitored at monthly intervals and nephritic symptoms observed by hematoxylin and eosin(H&E) and periodic acid-Schiff(PAS) staining.Western blot analysis of renal tissue was also employed.SAA treatment caused a significant reduction in the levels of anti-Sm autoantibodies and reduced renal histopathological changes and pathological effects.SAA treatment also significantly inhibited the phosphorylation of IKK,IκB and NFκB in renal tissues of lupus mice.In conclusion,the results suggest that SAA alleviates renal injury in pristane-induced SLE in BALB/c mice through inhibition of phosphorylation of IKK,IκB and NFκB.Yihuang Lin Yu Yan Huifang Zhang Yucai Chen Yangyang He Shoubao Wang Lianhua Fang Yang Lv Guanhua Du 2017Acta Pharmaceutica Sinica B2017,7,2:8
10Continuous nitrogen-doped carbon nanotube matrix for boosting oxygen electrocatalysis in rechargeable Zn-air batteries显示文摘Developing robust oxygen electrocatalyst with high-performance is very significant for practical rechargeable Zn-air battery.We report herein the preparation of three-dimensional continuous nanocarbon network composed of interconnected nitrogen-doped carbon nanotubes and its application as oxygen electrocatalysis in rechargeable Zn-air battery.Except the excellent electrochemical bifunctionality,this carbon nanotube matrix also delivers an impressive battery performance.Specifically,an opencircuit voltage of 1.50 V as well as a high power density of 220 m W cm^(-2) with remarkable cycling stability for 1600 h is achieved in the rechargeable Zn-air battery.The study not only provides an efficient bifunctional oxygen electrocatalyst but more importantly may pave significant concepts in designing robust electrode for long-life rechargeable Zn-air battery and other energy technologies.Guangda Chen Yangyang Xu Lei Huang Aboulkader Ibro Douka Bao Yu Xia 2021Journal of Energy Chemistry2021,30,4:7
11Circular Formation Flight Control for Unmanned Aerial Vehicles With Directed Network and External Disturbance显示文摘This paper proposes a new distributed formation flight protocol for unmanned aerial vehicles(UAVs)to perform coordinated circular tracking around a set of circles on a target sphere.Different from the previous results limited in bidirectional networks and disturbance-free motions,this paper handles the circular formation flight control problem with both directed network and spatiotemporal disturbance with the knowledge of its upper bound.Distinguishing from the design of a common Lyapunov fiunction for bidirectional cases,we separately design the control for the circular tracking subsystem and the formation keeping subsystem with the circular tracking error as input.Then the whole control system is regarded as a cascade connection of these two subsystems,which is proved to be stable by input-tostate stability(ISS)theory.For the purpose of encountering the external disturbance,the backstepping technology is introduced to design the control inputs of each UAV pointing to North and Down along the special sphere(say,the circular tracking control algorithm)with the help of the switching function.Meanwhile,the distributed linear consensus protocol integrated with anther switching anti-interference item is developed to construct the control input of each UAV pointing to east along the special sphere(say,the formation keeping control law)for formation keeping.The validity of the proposed control law is proved both in the rigorous theory and through numerical simulations.Yangyang Chen Rui Yu Ya Zhang Chenglin Liu 2020IEEE/CAA Journal of Automatica Sinica2020,7,2:7

13Exosomal LINC00355 derived from cancer-associated fibroblasts promotes bladder cancer cell resistance to cisplatin by regulating miR-34b-5p/ABCB1 axis显示文摘Cisplatin resistance is a major challenge for bladder cancer(BC).Evidence indicates that exosome derived from cancer-associated fibroblasts(CAF-Exo)can promote chemotherapy resistance in various human tumors by delivering bioactive molecules.We have previously demonstrated that CAF-derived exosomal LINC00355 promotes BC cell proliferation and invasion.However,the underlying mechanisms are still unclear.In this study,we aimed to investigate the role and mechanisms of CAF-derived exosomal LINC00355 in BC cell resistance to cisplatin.Exosomes were isolated from normal fibroblasts(NFs)and BC tumor-derived CAFs,namely,NF-Exo and CAF-Exo.CAFs were transfected with si-Ctrl or si-LINC00355 and then different exosomes were isolated,namely,CAF^(si-Ctrl)-Exo and CAF^(si-LINC00355)-Exo.The human BC cell lines(T24 and 5367)were incubated with NF-Exo,CAF-Exo,CAF^(si-Ctrl)-Exo,and CAF^(si-LINC00355)-Exo in the presence of cisplatin.MTT proliferation assay and flow cytometric analysis showed that CAF-Exo promoted BC cell resistance to cisplatin and upregulated ABCB1 expression in BC cells by transferring LINC00355 to BC cells.Luciferase activity assay confirmed the interaction between miR-34b-5p and LINC00355 or ABCB1.qRT-PCR and western blot analysis further showed that LINC00355 sponged miR-34b-5p to upregulate ABCB1 expression.However,the promoting effects of CAF-Exo on BC cell resistance to cisplatin were abolished by miR-34b-5p overexpression and ABCB1 silencing.In conclusion,exosomal LINC00355 derived from CAFs promotes BC cell resistance to cisplatin by regulating the miR-34b-5p/ABCB1 axis.Guangyue Luo Yangyang Zhang Zhonghui Wu Ligang Zhang Chaozhao Liang Xianguo Chen 2021Acta Biochimica et Biophysica Sinica2021,53,5:6
14Efficacy of acupuncture on fibromyalgia syndrome:a Meta-analysis显示文摘OBJECTIVE:To comprehensively evaluate the effectiveness of acupuncture as a treatment for fibromyalgiasyndrome.METHODS: Two review authors independently selected the trials for the Meta-analysis, assessed their methodological quality and extracted relevant data. A quality assessment was conducted according to the Cochrane Review Handbook 5.0.RevMan 5.0.20 software was used in the statistical analysis.RESULTS: A total of 523 trials were reviewed and 9trials were selected for Meta-analysis.(a) Compared acupuncture with sham acupuncture, there was a significant difference in the visual analogue scale,but no difference in the pressure pain threshold.Additionally,and there was a difference in the fibromyalgia impact questionnaire and the multidisciplinary pain inventory after 4 weeks of treatment,but no difference after 7 weeks of therapy. There was no difference in the numerical rating scale in weeks 3, 8 and 13.(b) Acupuncture versus drugs.There were differences in the VAS after 20 days of acupuncture and moxibustion treatment comparing with the drug amitriptyline, and after 4 weeks of acupuncture and moxibustion treatment comparing with the drug fluoxetine and amitriptyline.There were also differences in the number of tender points when comparing acupuncture with amitriptyline or fluoxetine. There was no difference in total efficiency when comparing acupuncture with amitriptyline after 4 weeks of treatment, but there were differences between the two groups 45 days after treatment.There were also differences in total efficiency comparing acupuncture with fluoxetine,and when comparing 4 weeks post-treatment of acupuncture with a combination of amitriptyline,oryzanol and vitamin B.(c) A comparison of acupuncture, drugs and exercise with drugs and exercise showed PPT differences in months 3 and 6.There was no difference between the two comparison groups after follow-up visits in months 12 and 24.CONCLUSION: Compared with sham acupuncture,there was not enough evidence to prove the efficacy of acupuncture therapy for the treatment of fibromyalgia. Some evidence testified that the effectiveness of acupuncture therapy for fibromyalgia was superior to drugs; however, the included trials were not of high quality or had high bias risks.Acupuncture combined with drugs and exercise could increase pain thresholds in the short term, but there is a need for higher quality randomized controlled trials to further confirm this.Yang Bai Yi Guo Hong Wang Bo Chen Zhankui Wang Yangyang Liu Xue Zhao Yinhong Li 2014Journal of Traditional Chinese Medicine2014,34,4:6
15Efficient Photoelectrochemical Water Splitting by g-C_3N_4/TiO_2 Nanotube Array Heterostructures显示文摘Well-ordered TiO_2 nanotube arrays(TNTAs)decorated with graphitic carbon nitride(g-C_3N_4) were fabricated by anodic oxidization and calcination process.First, TNTAs were prepared via the anodic oxidation of Ti foil in glycerol solution containing fluorinion and 20%deionized water. Subsequently, g-C_3N_4 film was hydrothermally grown on TNTAs via the hydrogen-bonded cyanuric acid melamine supramolecular complex. The results showed that g-C_3N_4 was successfully decorated on the TNTAs and the g-C_3N_4/TNTAs served as an efficient and stable photoanode for photoelectrochemical water splitting. The facile deposition method enables the fabrication of efficient and low-cost photoanodes for renewable energy applications.Changhai Liu Fang Wang Jin Zhang Ke Wang Yangyang Qiu Qian Liang Zhidong Chen 2018Nano-Micro Letters2018,10,2:6
16Vulnerability to drought-induced cavitation in shoots of two typical shrubs in the southern Mu Us Sandy Land, China显示文摘Salix psammophila and Caragana korshinskii are two typical shrubs in the southern Mu Us Sandy Land of China which are threatened by increasing water deficits related to climate change and large-scale human activities(e.g. coal mining and oil exploitation). In this study, we assessed their vulnerability to xylem embolism and the related anatomical traits in two-year-old regenerated shoots of these two shrubs to understand how they cope with drought environment. We also evaluated the in situ hydraulic safety margins to hydraulic failure from measurements of annual predawn and midday leaf water potentials. The results showed that S. psammophila stems had a higher water transport capacity than C. korshinskii stems. The stem xylem water potentials at 12%, 50% and 88% loss of conductivity were –1.11, –1.63 and –2.15 MPa in S. psammophila, respectively, and –1.37, –2.64 and –3.91 MPa in C. korshinskii, respectively. This suggested that C. korshinskii was more resistant to cavitation than S. psammophila. Compared with S. psammophila, C. korshinskii had shorter maximum vessel length, lower vessel density, smaller conductive area and higher wood density, which may contribute to its more resistant xylem. The in situ hydraulic safety margins indicated that even during the driest periods, both shrubs lived well above the most critical embolism thresholds, and the hydraulic safety margin was wider in C. korshinskii than in S. psammophila, suggesting that the regenerated shoots of both shrubs could function normally and C. korshinskii had greater hydraulic protection. These results provide the basis for an in-depth understanding of the survival, growth and functional behavior of these two shrubs under harsh and dry desert environments.LI Yangyang CHEN Weiyue CHEN Jiacun SHI Hui 2016Journal of Arid Land2016,8,1:5
17Catalysis under shell: Improved CO oxidation reaction confined in Pt@h-BN core-shell nanoreactors显示文摘Core-shell nanostructures consisting of active metal cores and protective shells often exhibit enhanced catalytic performance, in which reactants can access a small part of the core surfaces through the pores in the shells. In this study, we show that Pt nanoparticles (NPs) can be embedded into few-layer hexagonal boron nitride (h-BN) overlayers, forming Pt@h-BN core-shell nanocatalysts. The h-BN shells not only protect the Pt NPs under harsh conditions but also allow gaseous molecules such as CO and O2 to access a large part of the Pt surfaces through a facile intercalation process. As a result, the Pt@h-BN nanostructures act as nanoreactors, and CO oxidation reactions with improved activity, selectivity, and stability occur at the core-shell interfaces. The confinement effect exerted by the h-BN shells promotes the Pt-catalyzed reactions. Our work suggests that two-dimensional shells can function as robust but flexible covers on nanocatalyst surfaces and tune the surface reactivity.Mengmeng Sun Qiang Fu Lijun Gao Yanping Zheng Yangyang Li Mingshu Chen Xinhe Bao 2017Nano Research2017,10,4:5
18A single circular chromosome yeast显示文摘Dear editor,Most of the prokaryotic cells contain a single circular chromosome.In contrast, the eukaryotic cells usually contain multiple linear chromosomes. Recently, we artificially created a single linear chromosome yeast strain SY14 from native 16 chromosomes in a haploid Saccharomyces cerevisiae, which displays minor fitness defects.^1 In this study, we have created a new yeast strain which contains a single circular chromosome and apparently has not been found in nature.Yangyang Shao Ning Lu Chen Cai Fan Zhou Shanshan Wang Zhihu Zhao Guoping Zhao Jin-Qiu Zhou Xiaoli Xue Zhongjun Qin 2019Cell Research2019,29,1:5
19Magnetically rotational reactor for absorbing benzene emissions by ionic liquids显示文摘A magnetically rotational reactor (MRR) has been developed and used in absorbing benzene emissions. The MRR has a permanent magnet core and uses magnetic ionic liquid [bmim]FeCl4 as absorbent. Benzene emissions were carried by N2 into the MRR and were absorbed by the magnetic ionic liquid. The rotation of the permanent magnet core provided impetus for the agitation of the magnetic ionic liquid, enhancing mass transfer and making benzene better dispersed in the absorbent. 0.68 g benzene emissions could be absorbed by a gram of [bmim]FeCl4, 0.27 and 0.40 g/g higher than that by [bmim]PF6 and [bmim]BF4, respectively. The absorption rate increased with increasing rotation rate of the permanent magnet.Yangyang Jiang Chen Guo Huizhou Liu 2007China Particuology2007,5,1:4
20Exosomal LINC00355 derived from cancer-associated fibroblasts promotes bladder cancer cell proliferation and invasion by regulating miR-15a-5p/HMGA2 axis显示文摘We have previously demonstrated that exosomes derived from cancer-associated fibroblasts(CAFs)promote bladder cancer(BC)cell proliferation and invasion by transferring LINC00355.In this study,the molecular mechanisms underlying the pro-bladder cancer action of exosomal LINC00355 were explored.CAFs were obtained from BC tumor tissues,and normal fibroblasts(NFs)were obtained from adjacent normal tissues.Human BC cell lines(T24 and 5367)were incubated with NF-Exo(exosomes from NFs),CAF-Exo(exosomes from CAFs),CAFsi-Ctrl-Exo(exosomes from si-Ctrl-transfected CAFs),and CAFsi-LINC00355-Exo(exosomes from si-LINC00355-transfected CAFs).BC cell proliferation and invasion were evaluated by MTT and Transwell assays,respectively.The interaction between miR-15a-5p and LINC00355 or HMGA2 was examined by online bioinformatics analysis and luciferase activity assay.Results showed that HMGA2 is a direct target of miR-15a-5p,and LINC00355 functions as a sponge of miR-15a-5p to upregulate HMGA2 expression.The promoting effects of CAF-Exo on HMGA2 expression,cell proliferation,and cell invasion were hindered when LINC00355 expression was inhibited in BC cells.These promoting effects were also hindered when miR-15a-5p was overexpressed or HMGA2 was silenced in BC cells.In conclusion,exosomal LINC00355 derived from CAFs promotes BC cell proliferation and invasion by regulating miR-15a-5p/HMGA2 axis.Yangyang Zhang Guangyue Luo Shinian You Ligang Zhang Chaozhao Liang Xianguo Chen 2021Acta Biochimica et Biophysica Sinica2021,53,6:4
