| 2 | Additively manufactured biodegradable porous magnesium implants for elimination of implant-related infections:An in vitro and in vivo study显示文摘Magnesium(Mg)alloys that have both antibacterial and osteogenic properties are suitable candidates for orthopedic implants.However,the fabrication of ideal Mg implants suitable for bone repair remains challenging because it requires implants with interconnected pore structures and personalized geometric shapes.In this study,we fabricated a porous 3D-printed Mg-Nd-Zn-Zr(denoted as JDBM)implant with suitable mechanical properties using selective laser melting technology.The 3D-printed JDBM implant exhibited cytocompatibility in MC3T3-E1 and RAW267.4 cells and excellent osteoinductivity in vitro.Furthermore,the implant demonstrated excellent antibacterial ratios of 90.0% and 92.1% for methicillin-resistant S.aureus(MRSA)and Escherichia coli,respectively.The 3D-printed JDBM implant prevented MRSA-induced implant-related infection in a rabbit model and showed good in vivo biocompatibility based on the results of histological evaluation,blood tests,and Mg2+deposition detection.In addition,enhanced inflammatory response and TNF-α secretion were observed at the bone-implant interface of the 3D-printed JDBM implants during the early implantation stage.The high Mg^(2+)environment produced by the degradation of 3D-printed JDBM implants could promote M1 phenotype of macrophages(Tnf,iNOS,Ccl3,Ccl4,Ccl5,Cxcl10,and Cxcl2),and enhance the phagocytic ability of macrophages.The enhanced immunoregulatory effect generated by relatively fast Mg^(2+)release and implant degradation during the early implantation stage is a potential antibacterial mechanism of Mg-based implant.Our findings indicate that 3D-printed porous JDBM implants,having both antibacterial property and osteoinductivity,hold potential for future orthopedic applications. | Kai Xie Nanqing Wang Yu Guo Shuang Zhao Jia Tan Lei Wang Guoyuan Li Junxiang Wu Yangzi Yang Wenyu Xu Juan Chen Wenbo Jiang Penghuai Fu Yongqiang Hao | 2022 | Bioactive Materials2022，7，2： | 8 |
| 3 | A review:Synthesis,modification and photocatalytic applications of ZnIn_(2)S_(4)显示文摘Solar energy is an ideal energy source for solving energy shortages and serious environmental problems.In the past few decades,photocatalytic technology which uses solar energy to deal with the above problems has caused great interest.ZnIn_(2)S_(4),as a layered ternary metal chalcogenide compound,has a series of advantages such as the wide light absorption range and adjustable bandgap.It has been applied in the different fields of photocatalysis in recent years.This review introduced the crystal structures and growth mechanism of ZnIn_(2)S_(4)and summarized the preparation methods of ZnIn_(2)S_(4).Also,the promoted strategies of ZnIn_(2)S_(4)based photocatalytic system and their applications in the pollutant removal,hydrogen evolution,reduction of CO_(2),nitrogen fixation,and chemical synthesis was summarized.Furthermore,the challenges and development directions of the current ZnIn_(2)S_(4)based photocatalytic system were proposed.It is hoped that this review will help researchers design a better ZnIn_(2)S_(4)based photocatalytic system. | Jie Wang Sijia Sun Run Zhou Yangzi Li Zetian He Hao Ding Daimei Chen Weihua Ao | 2021 | Journal of Materials Science & Technology2021，，19： | 6 |
| 4 | SIRT7 orchestrates melanoma progression by simultaneously promoting cell survival and immune evasion via UPR activation显示文摘Melanoma is the most lethal type of skin cancer,originating from the malignant transformation of melanocyte.While the development of targeted therapy and immunotherapy has gained revolutionary advances in potentiating the therapeutic effect,the prognosis of patients with melanoma is still suboptimal.During tumor progression,melanoma frequently encounters stress from both endogenous and exogenous sources in tumor microenvironment.SIRT7 is a nuclear-localized deacetylase of which the activity is highly dependent on intracellular nicotinamide adenine dinucleotide(NAD+),with versatile biological functions in maintaining cell homeostasis.Nevertheless,whether SIRT7 regulates tumor cell biology and tumor immunology in melanoma under stressful tumor microenvironment remains elusive.Herein,we reported that SIRT7 orchestrates melanoma progression by simultaneously promoting tumor cell survival and immune evasion via the activation of unfolded protein response.We first identified that SIRT7 expression was the most significantly increased one in sirtuins family upon stress.Then,we proved that the deficiency of SIRT7 potentiated tumor cell death under stress in vitro and suppressed melanoma growth in vivo.Mechanistically,SIRT7 selectively activated the IRE1α-XBP1 axis to potentiate the pro-survival ERK signal pathway and the secretion of tumorpromoting cytokines.SIRT7 directly de-acetylated SMAD4 to antagonize the TGF-β-SMAD4 signal,which relieved the transcriptional repression on IRE1αand induced the activation of the IRE1α-XBP1 axis.Moreover,SIRT7 up-regulation eradicated anti-tumor immunity by promoting PD-L1 expression via the IRE1α-XBP1 axis.Additionally,the synergized therapeutic effect of SIRT7 suppression and anti-PD-1 immune checkpoint blockade was also investigated.Taken together,SIRT7 can be employed as a promising target to restrain tumor growth and increase the effect of melanoma immunotherapy. | Xiuli Yi Huina Wang Yuqi Yang Hao Wang Hengxiang Zhang Sen Guo Jianru Chen Juan Du Yangzi Tian Jingjing Ma Baolu Zhang Lili Wu Qiong Shi Tianwen Gao Weinan Guo Chunying | 2023 | Signal Transduction and Targeted Therapy2023，8，4： | 1 |
| 5 | Bandgap engineering of tetragonal phase CuFeS_(2)quantum dots via mixed-valence single-atomic Ag decoration for synergistic Cr(VI)reduction and RhB degradation显示文摘Bandgap engineering through single-atom site binding on semiconducting photocatalyst can boost the intrinsic activity,selectivity,carrier separation,and electron transport.Here,we report a mixed-valence Ag(0)and Ag(I)single atoms co-decorated semiconducting chalcopyrite quantum dots(Ag/CuFeS_(2)QDs)photocatalyst.It demonstrates efficient photocatalytic performances for specific organic dye(rhodamine B,denoted as RhB)as well as inorganic dye(Cr(VI))removal in water under natural sunlight irradiation.The RhB degradation and Cr(VI)removal efficiencies by Ag/CuFeS_(2)QDs were 3.55 and 6.75 times higher than those of the naked CuFeS_(2)QDs at their optimal pH conditions,respectively.Besides,in a mixture of RhB and Cr(VI)solution under neutral condition,the removal ratio has been elevated from 30.2%to 79.4%for Cr(VI),and from 95.2%to 97.3%for RhB degradation by using Ag/CuFeS_(2)QDs after 2 h sunlight illumination.The intrinsic mechanism for the photocatalytic performance improvement is attributed to the narrow bandgap of the single-atomic Ag(I)anchored CuFeS_(2)QDs,which engineers the electronic structure as well as expands the optical light response range.Significantly,the highly active Ag(0)/CuFeS_(2)and Ag(I)/CuFeS_(2)effectively improve the separation efficiency of the carriers,thus enhancing the photocatalytic performances.This work presents a highly efficient single atom/QDs photocatalyst,constructed through bandgap engineering via mixed-valence single noble metal atoms binding on semiconducting QDs.It paves the way for developing high-efficiency single-atom photocatalysts for complex pollutions removal in dyeing wastewater environment. | Yangzi Shangguan Yuanhao Zhou Renji Zheng Xuezhen Feng Qiuyue Ge Ranhao Wang Dazhong Yang Wenfei Wei Xiaoyong Wu Jia Lin Hong Chen | 2021 | Chinese Chemical Letters2021，32，11： | 1 |

| 9 | Micropaleontology and palaeoclimate during the early Cretaceous in the Lishu depression,Songliao basin,Northeast China显示文摘Diverse and abundant microfossils,such as palynomorphs,algae and Ostracoda,were collected from lower Cretaceous strata of Lishu depression,located in southeastern Songliao basin,and were identified and classified in order to provide relevant,detailed records for paleoclimate research.The early Cretaceous vegetation and climate of southeastern Songliao basin have been inferred from the analysis of palynomorph genera,algae and Ostracoda of the LS1 and SW110 wells.The lower Cretaceous strata include,in ascending stratigraphic order,the Shahezi,Yingcheng and Denglouku formations.Palynological assemblages for each formation,based on biostratigraphic and statistical analyses,provide an assessment of their longitudinal variations.During deposition of the Shahezi Formation,the climate was mid-subtropical.Vegetation consisted of coniferous forest and herbage.During deposition of the Yingcheng Formation,the climate was south Asian tropical.Vegetation consisted mainly of coniferous forest and herbal shrub.In addition,fresh and saline non-marine water dominated the lacustrine setting during deposition of these formations.Deposition of the Denglouku Formation,however,occurred under a hot and dry tropical climate.The vegetation was mostly coniferous forest and lake waters became saline.Palaeoclimate variation is correlated by the lake level change and the development of sedimentary facies.Palaeoclimate contribute to the formation of hydrocarbon source rocks and reservoir. | Wei Yan Tailiang Fan Hongyu Wang Chen Zhu Zhiqian Gao Xiangjie Meng Yangzi Sun Fan Yang | 2017 | Geoscience Frontiers2017，8，1： | 0 |
| 10 | Determination of Tebuconazole Residue in Apples and Vegetables by Matrix Solid Phase Dispersion-Gas Chromatography显示文摘[Objective] The study aimed to determine tebuconazole residue in apples and vegetables using matrix solid phase dispersion-gas chromatography( MSPD-GC).[Method] The effects of extraction and determination conditions on the detection of tebuconazole left in apples and vegetables were analyzed,and the optimum extraction conditions were determined.[Result] The recovery rate of tebuconazole was the highest when the ratio of a sample to florisil dispersant was 1∶4,and the mixture of hexane and acetone( 1∶1) with total volume of 8 ml was as the eluant.Under the optimum conditions,the relative standard deviation( RSD) of the method was 4.9%-7.6%,and the detection limit was 0.1 μg/g,while the recovery rate of tebuconazole changed from 86.7% to 95.2%.[Conclusion] The method was simple,accurate,sensitive and applicable to the determination of tebuconazole in agricultural products. | Peng Cao Yunjie Ma Yue Cao Jianyun Wang Yangzi Wang | 2013 | Meteorological and Environmental Research2013，4，7： | 0 |
| 11 | Identifying QTL and candidate genes for prolificacy in maize显示文摘In maize,prolificacy,the number of ears per plant,is a trait of interest to maize breeders for breeding high grain-yielding cultivars or specialty corn,as well as being a model trait for decoding the molecular mechanism of maize evolution.Its genetic basis remains largely unknown.We identified a stable quantitative trait locus,qEN7,for ear number on chromosome 7 in both F2 and F2:3 populations derived from a single cross between the nonprolific inbred line Mo17 and the prolific inbred line LAN404 derived from the landrace PI217404.qEN7 explained 10.7%-11.9%of phenotypic variation,and the LAN404 allele at this locus was associated with an increase of around one ear per plant.qEN7 was confined by fine-mapping to a 0.56-Mb region containing eight annotated genes.Analysis of selection,gene expression patterns in various maize tissues,and sequence polymorphisms between the two parental lines suggested that Zm00001d020683,which encodes a putative INDETERMINATE DOMAIN(IDD)transcription factor,is the most likely candidate gene underlying qEN7.Zm00001d020683 is expressed mainly in the vegetative meristem,immature ears,and internodes and has undergone selection during maize improvement.The identification of qEN7 and the prediction of its candidate gene sheds some light on the evolution of maize ear number and provides a novel resource for breeding of multi-ear maize cultivars. | Min Wang Renyu Zhang Yangzi Zhao Jieyuan Yao Weiya Li Zhixing Yang Fei Sun Xiaohong Yang | 2023 | The Crop Journal2023，11，2： | 0 |
