| 1 | Super stable CsPbBr3@SiO2 tumor imaging reagent by stress-response encapsulation显示文摘Great photoelectric properties can herald the high potentials of CsPbBr3 nanocrystals(NCs)to function as the fluorescent probes for early tumor diagnosis.However,the intrinsic water vulnerability of CsPbBr3 NCs highly restricts their biomedical applications.To conquer this challenge,we herein introduce a nature inspired'stress-response'method to tightly encapsulate CsPbBr3 into SiO2 nano-shells that can dramatically improve the water stability of CsPbBr3@SiO2 nanoparticles for over 48 h.We further highlighted the advantageous features of CsPbBr3@SiO2 by using them as the fluorescent probes for CT26 tumor cell imaging with their high water stability,biocompatibility,and low cytotoxicity.Our work for the first time exhibited the potential of lead halide perovskite NCs for tumor diagnosis,and can highly anticipate the further in vivo biomedical applications that light up live cells. | Wentao Song Yiming Wang Bing Wang Yingfang Yao Wenguang Wang Jinhui Wu Qing Shen Wenjun Luo Zhigang Zou | 2020 | Nano Research2020，13，3： | 7 |

| 3 | A novel selective autophagy receptor,CCDC50,delivers K63 polyubiquitination-activated RIG-I/MDA5 for degradation during viral infection显示文摘Autophagy is a con served process that delivers cytosolic substa nces to the lysosome for degradatio n,but its direct role in the regulation of antiviral inn ate immu nity remains poorly un derstood.Here,through high-throughput screeni ng,we discovered that CCDC50 functions as a previously unknown autophagy receptor that negatively regulates the type I interferon(IFN)signaling pathway initiated by RIG-I-like receptors(RLRs),the sensors for RNA viruses.The expression of CCDC50 is enhanced by viral infection,and CCDC50 specifically recognizes K63-polyubiquitinated RLRs,thus delivering the activated RIG-I/MDA5 for autophagic degradation.The associatio n of CCDC50 with phagophore membrane protei n LC3 is con firmed by crystal structure analysis.In contrast to other known autophagic cargo receptors that associate with either the LIR-docking site(LDS)or the UIMdocking site(UDS)of LC3,CCDC50 can bind to both LDS and UDS,representing a new type of cargo receptor.In mouse models with RNA virus infection,CCDC50 deficiency reduces the autophagic degradation of RIG-I/MDA5 and promotes type I IFN responses,resulting in enhaneed viral resistance and improved survival rates.These results reveal a new link between autophagy and antiviral innate immune resp on ses and provide additional in sights into the regulatory mecha nisms of RLR-mediated antiviral signaling. | Panpan Hou Kongxiang Yang Penghui Jia Lan Liu Yuxin Lin Zibo Li Jun Li Shuliang Chen Shuting Guo Ji'An Pan Junyu Wu Hong Peng Weijie Zeng Chunmei Li Yingfang Liu Deyin Guo | 2021 | Cell Research2021，31，1： | 5 |
| 4 | Cryo-self-assembled silk fibroin sponge as a biodegradable platform for enzyme-responsive delivery of exosomes显示文摘Although advances in protein assembly preparation have provided a new platform for drug delivery during tissue engineering,achieving long-term controlled exosome delivery remains a significant challenge.Diffusion-dominated exosome release using protein hydrogels results in burst release of exosomes.Here,a fibroin-based cryo-sponge was developed to provide controlled exosome release.Fibroin chains can self-assemble into silk I structures under ice-cold conditions when annealed above the glass transition temperature.Exosome release is enzyme-responsive,with rates primarily determined by enzymatic degradation of the scaffolds.In vivo experiments have demonstrated that exosomes remain in undigested sponge material for two months,superior to their retention in fibrin glue,a commonly used biomaterial in clinical practice.Fibroin cryo-sponges were implanted subcutaneously in nude mice.The exosome-containing sponge group exhibited better neovascularization and tissue ingrowth effects,demonstrating the efficacy of this exosome-encapsulating strategy by realizing sustained release and maintaining exosome bioactivity.These silk fibroin cryo-sponges containing exosomes provide a new platform for future studies of exosome therapy. | Muyang Sun Qi Li Huilei Yu Jin Cheng Nier Wu Weili Shi Fengyuan Zhao Zhenxing Shao Qingyang Meng Haifeng Chen Xiaoqing Hu Yingfang Ao | 2022 | Bioactive Materials2022，7，2： | 4 |
| 5 | Extraterrestrial artificial photosynthetic materials for in-situ resource utilization显示文摘Aerospace milestones in human history,including returning to the moon and manned Martian missions,have been implemented in recent years.Space exploration has become one of the global common goals,and to ensure the survival and development of human beings in the extraterrestrial extreme environment has been becoming the basic ability and technology of manned space exploration.For the purpose of fulfilling the goal of extraterrestrial survival,researchers in Nanjing University and the China Academy of Space Technology proposed extraterrestrial artificial photosynthesis(EAP)technology.By simulating the natural photosynthesis of green plants on the Earth,EAP converts CO_(2)/H_(2)O into fuel and O_(2)in an in-situ,accelerated and controllable manner by using waste CO_(2)in the confined space of spacecraft,or abundant CO_(2)resources in extraterrestrial celestial environments,e.g.Mars.Thus,the material loading of manned spacecraft can be greatly reduced to support affordable and sustainable deep space exploration.In this paper,EAP technology is compared with existing methods of converting CO_(2)/H_(2)O into fuel and O_(2)in the aerospace field,especially the Sabatier method and Bosch reduction method.The research progress of possible EAP materials for in-situ utilization of extraterrestrial resources are also discussed in depth.Finally,this review lists the challenges that the EAP process may encounter,which need to be focused on for future implementation and application.We expect to deepen the understanding of artificial photosynthetic materials and technologies,and aim to strongly support the development of manned spaceflight. | Liuqing Yang Ce Zhang Xiwen Yu Yingfang Yao Zhaosheng Li Congping Wu Wei Yao Zhigang Zou | 2021 | National Science Review2021，8，8： | 3 |
| 6 | Difficult and complicated oral ulceration:an expert consensus guideline for diagnosis显示文摘The complexity of oral ulcerations poses considerable diagnostic and therapeutic challenges to oral specialists.The expert consensus was conducted to summarize the diagnostic work-up for difficult and complicated oral ulcers,based on factors such as detailed clinical medical history inquiry,histopathological examination,and ulceration-related systemic diseases screening.Not only it can provide a standardized procedure of oral ulceration,but also it can improve the diagnostic efficiency,in order to avoid misdiagnosis and missed diagnosis. | Xin Zeng Xin Jin Liang Zhong Gang Zhou Ming Zhong Wenmei Wang Yuan Fan Qing Liu Xiangmin Qi Xiaobing Guan Zhimin Yan Xuemin Shen Yingfang Wu Lijie Fan Zhi Wang Yuan He Hongxia Dan Jiantang Yang Hui Wang Dongjuan Liu Hui Feng Kai Jiao Qianming Chen | 2022 | International Journal of Oral Science2022，14，2： | 2 |
| 7 | Surpassing electrocatalytic limit of earth-abundant Fe^(4+)embedded in N-doped graphene for(photo)electrocatalytic water oxidation显示文摘Developing highly active,cost-effective,and environmental friendly oxygen evolution reaction(OER)electrocatalysts facilitates various(photo)electrochemical processes.In this work,Fe3N nanoparticles encapsulated into N-doped graphene nanoshells(Fe_(3)N@NG)as OER electrocatalysts in alkaline media were reported.Both the experimental and theoretical comparison between Fe_(3) N@NG and Fe_(3)N/NG,specifically including in situ Mossbauer analyses,demonstrated that the NG nanoshells improved interfacial electron transfer process from Fe_(3)N to NG to form high-valence Fe^(4+)ions(Fe^(4+)@NG),thus modifying electronic properties of the outer NG shells and subsequently electron transfer from oxygen intermediate to NG nanoshells for OER catalytic process.Meanwhile,the NG nanoshells also protected Fe-based cores from forming OER inactive and insulated Fe_(2)O_(3),leading to high OER stability.As a result,the as-formed Fe^(4+)@NG shows one of the highest electrocatalytic efficiency among reported Fe-based OER electrocatalysts,which can as well highly improve the photoelectrochemical water oxidation when used as the cocatalysts for the Fe_(2)O_(3) nanoarray photoanode. | Wenjia Xue Feng Cheng Menglu Li Wenjian Hu Congping Wu Bing Wang Kuowei Liao ZhenTao Yu Yingfang Yao Wenjun Luo Zhigang Zou | 2021 | Journal of Energy Chemistry2021，30，3： | 2 |
| 8 | Medical Additive Manufacturing: From a Frontier Technology to the Research and Development of Products显示文摘1.Research and development(R&D)and the challenges of raw materials for medical additive manufacturing Raw materials for medical additive manufacturing have a wide range of commonalities that are also seen in many other fields,making them an important basis in the field of three-dimensional(3D)printing.Problems and challenges related to material types,powder properties,formability,viscoelasticity,and so forth also share common features.For example,many metal materials are used in the field of aviation,while metals,polymers,and inorganic materials are used in the field of biomedicine.The most widely used materials in biomedicine are biocompatible.Various homogeneous and non-homogeneous composites are also available for 3D printing,and impose an additional challenge in additive manufacturing;the use of heterogeneous composites in 3D printing is particularly challenging. | Guixing Qiu Wenjiang Ding Wei Tian Ling Qin Yu Zhao Lianmeng Zhang Jian Lu Daijie Chen Guangyi Yuan Chengtie Wu Bingheng Lu Ruxu Du Jimin Chen Mo Elbestawi Zhongwei Gu Dichen Li Wei Sun Yuanjin Zhao Jie He Dadi Jin Bin Liu Kai Zhang Jianmo Li Kam WLeong Dewei Zhao Dingjun Hao Yingfang Ao Xuliang Deng Huilin Yang ShaoKeh Hsu Yingqi Chen Long Li Jianping Fan Guohui Nie Yun Chen Hui Zeng Wei Chen Yuxiao Lai | 2020 | Engineering2020，6，11： | 1 |
| 9 | Mediator tail module subunits MED16 and MED25 differentially regulate abscisic acid signaling in Arabidopsis显示文摘MED25 has been implicated as a negative regulator of the abscisic acid(ABA)signaling pathway.However,it is unclear whether other Mediator subunits could associate with MED25 to participate in the ABA response.Here,we used affinity purification followed by mass spectrometry to uncover Mediator subunits that associate with MED25 in transgenic plants.We found that at least26 Mediator subunits,belonging to the head,middle,tail,and CDK8 kinase modules,were copurified with MED25 in vivo.Interestingly,the tail module subunit MED16 was identified to associate with MED25 under both mock and ABA treatments.We further showed that the disruption of MED16 led to reduced ABA sensitivity compared to the wild type.Transcriptomic analysis revealedthattheexpressionofseveral ABA-responsive genes was significantly lower in med16 than those in wild type.Furthermore,we discovered that MED16 may possibly compete with MED25 to interact with the key transcription factor ABA INSENSITIVE 5(ABI5)to positively regulate ABA signaling.Consistently,med16 and med25 mutants displayed opposite phenotypes in ABA response,cuticle permeability,and differential ABI5-mediated EM1 and EM6 expression.Together,our data indicate that MED16 and MED25 differentially regulate ABA signaling byantagonisticallyaffectingABI5-mediated transcription in Arabidopsis. | Pengcheng Guo Leelyn Chong Fangming Wu Chuan-Chih Hsu Chuanyou Li Jian-Kang Zhu Yingfang Zhu | 2021 | Journal of Integrative Plant Biology2021，63，4： | 1 |
| 10 | Optical Design and Preparation of High Performance Mo/NiAlN/NiAlON/SiO_2 Solar Selective Absorbing Coating显示文摘A new solar selective absorbing coating of Mo/NiAlN/NiAlON/SiO_2 multilayer was prepared on stainless steel(SS) substrates by magnetron sputtering for solar thermal power applications. The optical constants and thickness of individual layers were simulated using the Scout software based on the experimentally measured reflectance and transmittance spectra of individual layers. The coating of Mo/NiAlN/NiAlON/SiO_2 with an ideal solar absorptance(α) of 0.945 in the solar spectrum range was designed via the optical constants of each layer in the Scout software. The Mo/NiAlN/NiAlON/SiO_2 coating was deposited via the optimized layer thickness. A good spectral selectivity with absorptance(α=0.936) and emittance(ε=0.09, T=80 ℃) was obtained. This method, which incorporates the optical simulation with the related experiments, provides a convenient approach to obtain the ideal solar selective absorbing coatings. | LIU Yingfang WANG Cong SUN Ying WU Yongxin NING Yuping WANG Wenwen ZHANG Yong ZHAO Shuxi | 2015 | Journal of the Chinese Ceramic Society2015，，4： | 1 |
| 11 | Photosynthetic microorganisms coupled photodynamic therapy for enhanced antitumor immune effect显示文摘The ideal photodynamic therapy(PDT)should effectively remove the primary tumor,and produce a stronger immune memory effect to inhibit the tumor recurrence and tumor metastasis.However,limited by the hypoxic and immunosuppressive microenvironment,the PDT efficiency is apparently low.Here,Chlorella(Chl.)is exploited to enhance local effect by producing oxygen to reverse hypoxia,and release adjuvants to reverse immunosuppressive microenvironment to enhance abscopal effect afterwards.Results from different animal models indicated that Chl.could enhance local effect and PDT related immune response.Ultimately,Chl.coupled PDT elicited anti-tumor effects toward established primary tumors(inhibition rate:90%)and abscopal tumors(75%),controlled the challenged tumors(100%)and alleviated metastatic tumors(90%).This Chl.coupled PDT strategy can also produce a stronger anti-tumor immune memory effect.Overall,this Chl.coupled PDT strategy generates enhanced local tumor killing,boosts PDT-induced immune responses and promotes anti-tumor immune memory effect,which may be a great progress for realizing systemic effect of PDT. | Haoran Wang Honghui Liu Yunfei Guo Wenjing Zai Xianghui Li Wei Xiong Xiaozhi Zhao Yingfang Yao Yiqiao Hu Zhigang Zou Jinhui Wu | 2022 | Bioactive Materials2022，7，6： | 0 |
| 12 | Single Exposure to Cocaine Impairs Reinforcement Learning by Potentiating the Activity of Neurons in the Direct Striatal Pathway in Mice显示文摘Plasticity in the glutamatergic synapses on striatal medium spiny neurons(MSNs)is not only essential for behavioral adaptation but also extremely vulnerable to drugs of abuse.Modulation on these synapses by even a single exposure to an addictive drug may interfere with the plasticity required by behavioral learning and thus produce impairment.In the present work,we found that the negative reinforcement learning,escaping mild foot-shocks by correct nose-poking,was impaired by a single in vivo exposure to 20 mg/kg cocaine 24 h before the learning in mice.Either a single exposure to cocaine or reinforcement learning potentiates the glutamatergic synapses on MSNs expressing the striatal dopamine 1(D1)receptor(D1-MSNs).However,24 h after the cocaine exposure,the potentiation required for reinforcement learning was disrupted.Specific manipulation of the activity of striatal D1-MSNs in D1-cre mice demonstrated that activation of these MSNs impaired reinforcement learning in normal D1-cre mice,but inhibition of these neurons reversed the reinforcement learning impairment induced by cocaine.The results suggest that cocaine potentiates the activity of direct pathway neurons in the dorsomedial striatum and this potentiation might disrupt the potentiation produced during and required for reinforcement learning. | Zhijun Diao Yuanyuan Di Meilin Wu Chenyang Zhai Mengsi Kang Yongfeng Li Yingxun Liu Chunling Wei Qiaohua Zheng Jing Han Zhiqiang Liu Yingfang Tian Wei Ren | 2021 | Neuroscience Bulletin2021，37，8： | 0 |
| 13 | An Extrinsic Faradaic Layer on CuSn for High-Performance Electrocatalytic CO_(2) Reduction显示文摘An intrinsic Faradaic layer on the surface of a metal electrocatalyst is usually considered an active site for CO_(2) reduction.Different strategies have been used to improve the performance of CO_(2) reduction by adjusting the intrinsic Faradaic layer.However,it is still challenging to achieve CO_(2) reduction with high activity,selectivity,and stability.In this study,for the first time,we improve the three parameters simultaneously by introducing a Zn(OH)_(x) over layer onto a CuSn electrocatalyst.We find that the intrinsic Faradaic layer of Sn(OH)_(x) on the surface of CuSn provides active sites for CO_(2) reduction,while Zn(OH)_(x) plays multiple roles as an adsorption/activation layer,a cover layer,and a protective layer.Further studies suggest that the enhanced activity comes from a Faradaic reaction of Zn(OH)_(x) during CO_(2) reduction,which can be considered as an extrinsic Faradaic layer.This new strategy of introducing an extrinsic Faradaic layer can deepen understanding of electrocatalytic process and offers guidance to design other high-performance electrocatalysts. | Feilong Ren Wenjian Hu Cheng Wang Pin Wang Wenbo Li Congping Wu Yingfang Yao Wenjun Luo Zhigang Zou | 2022 | CCS Chemistry2022，4，5： | 0 |
