1Facile synthesis of ultrathin metal-organic framework nanosheets for Lewis acid catalysis显示文摘Ultrathin metalorganic framework (MOF) nanosheets are attracting great interest in catalysis due to their unique and intriguing two-dime nsional (2D) features. Although many progresses have been achieved, it is still highly desirable to develop novel strategies for controllable synthesis of the well-defined ultrathin MOF nanosheets. Herein we report a polyvinylpyrrolidone (PVP)-assisted route to synthesize the ultrathin Ni-MOF nanosheets characteristic of 1.5 nm in thickness, in which PVP is reacted with 2-aminoterephthalic acid (H2BDC-NH2) via formation of C=N bon d, followed by coord inatio n with Ni2+ io ns to form the ultrathi n MOF n anosheets. Impressively, when used in the Kno eve nagel condensation reactions of propane dinitrile with different aldehydes, ultrathin Ni-MOF nanosheets display the significantly enhanced catalytic activity and good stability in respect with the bulk Ni-MOF, mainly owing to the exposed active sites as well as facile mass transfer and diffusion of substrates and products.Xiaofei Zhang Lin Chang Zhongjie Yang Yanan Shi Chang Long Jianyu Han Binhao Zhang Xueying Qiu Guodong Li Zhiyong Tang 2019Nano Research2019,12,2:11

3Improvement in affinity and thermostability of a fully human antibody against interleukin-17A by yeast-display technology and CDR grafting显示文摘Monoclonal antibodies(m Abs) are widely used in many fields due to their high specificity and ability to recognize a broad range of antigens. IL-17 A can induce a rapid inflammatory response both alone and synergistically with other proinflammatory cytokines. Accumulating evidence suggests that therapeutic intervention of IL-17 A signaling offers an attractive treatment option for autoimmune diseases and cancer. Here, we present a combinatorial approach for optimizing the affinity and thermostability of a novel anti-h IL-17 A antibody. From a large na?ve phage-displayed library, we isolated the anti-IL-17 A m Ab 7 H9 that can neutralize the effects of recombinant human IL-17 A. However, the modest neutralization potency and poor thermostability limit its therapeutic applications. In vitro affinity optimization was then used to generate 8 D3 by using yeast-displayed random mutagenesis libraries.This resulted in four key amino acid changes and provided an approximately 15-fold potency increase in a cell-based neutralization assay. Complementarity-determining regions(CDRs) of 8 D3 were further grafted onto the stable framework of the hu Fv 4 D5 to improve thermostability. The resulting hybrid antibody9 NT/S has superior stabilization and affinities beyond its original antibody. Human fibrosarcoma cellbased assays and in vivo analyses in mice indicated that the anti-IL-17 A antibody 9 NT/S efficiently inhibited the secretion of IL-17 A-induced proinflammatory cytokines. Therefore, this lead anti-IL-17 A m Ab might be used as a potential best-in-class candidate for treating IL-17 A related diseases.Wei Sun Zhaona Yang Heng Lin Ming Liu Chenxi Zhao Xueying Hou Zhuowei Hu Bing Cuin 2019Acta Pharmaceutica Sinica B2019,9,5:4

5Cerebral perfusion in corresponding blood supply areas of transient ischemic attack patients with intracranial stenosis Seven cases of diamox-perfusion verified by magnetic resonance-perfusion-weighted imaging显示文摘BACKGROUND: Due to collateral circulation and cerebrovascular reserve, arterial stenosis and reduced cerebral blood flow may not necessarily indicate impaired cerebral perfusion. Therefore, according to degree of stenosis and clinical symptoms, interventional surgery to relieve arterial stenosis in transient ischemic attack (TIA) patients with major intracranial stenosis is imprudent. Rather, cerebral perfusion and reserve capacity are direct indicators for the assessment of degree and presence of cerebral ischemia. OBJECTIVE: To evaluate cerebral perfusion and reserve in TIA patients with major intracranial stenosis or occlusion using magnetic resonance-perfusion-weighted imaging (MR-PWI) data prior to and following diamox administration. DESIGN, TIME AND SETTING: A self-comparative, neuroimaging observation was performed at the Neurological Department and Radiological Center of the First Affiliated Hospital of Jinan University between December 2007 and April 2009. PARTICIPANTS: Seven acute TIA patients, who were admitted to the Neurological Department of the First Affiliated Hospital of Jinan University between December 2007 and April 2009, were enrolled in the present study. Magnetic resonance imaging confirmed that no acute cerebral infarction happened, nor did bleeding exist. Magnetic resonance angiography, transcranial Doppler ultrasound, and/or digital subtraction angiography confirmed the presence of major intracranial arterial stenosis. Clinical symptoms corresponded to blood supplying regions of the arterial stenosis. METHODS: Baseline MR-PWI was performed on seven patients with intracranial stenosis or occlusion. Two grams of acetazolamide (diamox) were orally administered after 2 days. A second PWI was performed after 2 hours to compare cerebral perfusion parameters prior to and following diamox administration. MAIN OUTCOME MEASURES: PWI results of cerebral perfusion prior to and following diamox administration. RESULTS: The baseline PWI from five patients indicated decreased cerebral perfusion areas. Following oral administration of diamox, cerebral perfusion significantly decreased in those areas. Moreover, new areas of decreased cerebral perfusion were observed in two out of the five patients. In one patient, no significant decrease in cerebral perfusion was found. In another patient, baseline PWI indicated decreased cerebral perfusion in the left hemisphere. However, normal perfusion was observed in both cerebral lobes following diamox administration. CONCLUSION: TIA patients with intracranial stenosis, who are diagnosed by PWI and exhibited decreased cerebral perfusion and reserve, might require further treatment such as intervention by angioplasty.Li'an Huang Xuewen Song Anding Xu Xueying Ling Zhichao Lin 2010Neural Regeneration Research2010,5,1:3
6Improved Electrochemical Performance Based on Nanostructured SnS_2@CoS_2–rGO Composite Anode for Sodium-Ion Batteries显示文摘A promising anode material composed of SnS_2@CoS_2 flower-like spheres assembled from SnS_2 nanosheets and CoS_2 nanoparticles accompanied by reduced graphene oxide(rGO) was fabricated by a facile hydrothermal pathway. The presence of rGO and the combined merits of SnS_2 and CoS_2 endow the SnS_2@-CoS_2–rGO composite with high conductivity pathways and channels for electrons and with excellent properties as an anode material for sodium-ion batteries(SIBs). A high capacity of 514.0 mAh g^(-1) at a current density of200 m A g^(-1) after 100 cycles and a good rate capability can be delivered. The defined structure and good sodium-storage performance of the SnS_2@CoS_2–rGO composite demonstrate its promising application in high-performance SIBs.Xia Wang Xueying Li Qiang Li Hongsen Li Jie Xu Hong Wang Guoxia Zhao Lisha Lu Xiaoyu Lin Hongliang Li Shandong Li 2018Nano-Micro Letters2018,10,3:2
7Triblock copolymer-assisted construction of 20 nm-sized ytterbium-doped TiO_2 hollow nanostructures for enhanced solar energy utilization efficiency显示文摘Rare-earth doped titania single-crystalline hollow nanoparticles of 20 nm are constructed via a simple sol-gel process. Amphiphilic ABA tri-block copolymers played a key role in assisting the formation of hollow structure, for which a hollow nanostructure growth mechanism is proposed. By introducing rare earth into the synthesis process, the as-prepared nanoparticles exhibit near-infrared light absorption properties. Photo-decomposition efficiency of Orange II azo dye can be successfully evaluated when using Yb3+-doped Ti O2 hollow nanoparticles as photocatalysts; it is more than two times higher than the pure Ti O2 hollow nanoparticles. The hollow nanostructured Yb3+-doped Ti O2 samples are exploited as photoanodes in N719- sensitized solar cells and prove able to improve the photoelectric conversion efficiency by measuring the solar cell parameters of dye-sensitized solar cells(DSSCs) under simulative sunlight.Lin Cheng Xuefeng Xu Yuyan Fang Yan Li Jiaxi Wang Guojia Wan Xueying Ge Liangjie Yuan Keli Zhang Lei Liao Quan Yuan 2015Science China Chemistry2015,58,5:2

14Spatiotemporal variation of land surface temperature and its driving factors in Xinjiang,China显示文摘Land surface temperature(LST) directly affects the energy balance of terrestrial surface systems and impacts regional resources, ecosystem evolution, and ecosystem structures. Xinjiang Uygur Autonomous Region is located at the arid Northwest China and is extremely sensitive to climate change. There is an urgent need to understand the distribution patterns of LST in this area and quantitatively measure the nature and intensity of the impacts of the major driving factors from a spatial perspective, as well as elucidate the formation mechanisms. In this study, we used the MOD11C3 LST product developed on the basis of Moderate Resolution Imaging Spectroradiometer(MODIS) to conduct regression analysis and determine the spatiotemporal variation and differentiation pattern of LST in Xinjiang from 2000 to 2020. We analyzed the driving mechanisms of spatial heterogeneity of LST in Xinjiang and the six geomorphic zones(the Altay Mountains, Junggar Basin, Tianshan Mountains, Tarim Basin, Turpan-Hami(Tuha) Basin, and Pakakuna Mountain Group) using geographical detector(Geodetector) and geographically weighted regression(GWR) models. The warming rate of LST in Xinjiang during the study period was 0.24℃/10a, and the spatial distribution pattern of LST had obvious topographic imprints, with 87.20% of the warming zone located in the Gobi desert and areas with frequent human activities, and the cooling zone mainly located in the mountainous areas. The seasonal LST in Xinjiang was at a cooling rate of 0.09℃/10a in autumn, and showed a warming trend in other seasons. Digital elevation model(DEM), latitude, wind speed, precipitation, normalized difference vegetation index(NDVI), and sunshine duration in the single-factor and interactive detections were the key factors driving the LST changes. The direction and intensity of each major driving factor on the spatial variations of LST in the study area were heterogeneous. The negative feedback effect of DEM on the spatial differentiation of LST was the strongest. Lower latitudes, lower vegetation coverage, lower levels of precipitation, and longer sunshine duration increased LST. Unused land was the main heat source landscape, water body was the most important heat sink landscape, grassland and forest land were the land use and land cover(LULC) types with the most prominent heat sink effect, and there were significant differences in different geomorphic zones due to the influences of their vegetation types, climatic conditions, soil types, and human activities. The findings will help to facilitate sustainable climate change management, analyze local climate and environmental patterns, and improve land management strategies in Xinjiang and other arid areas.ZHANG Mingyu CAO Yu ZHANG Zhengyong ZHANG Xueying LIU Lin CHEN Hongjin GAO Yu YU Fengchen LIU Xinyi 2024Journal of Arid Land2024,16,3:0
15Interface-enhanced thermoelectric output power in CrN/SrTiO_(3-x) heterostructure显示文摘Thermoelectric devices enable direct conversion between thermal and electrical energy.Recent studies have indicated that the thin film/substrate heterostructure is effective in achieving high thermoelectric performance via decoupling the Seebeck coefficient and electrical conductivity otherwise adversely inter-dependent in homogenous bulk materials.However,the mechanism underlying the thin film/substrate heterostructure thermoelectricity remains unclear.In addition,the power output of the thin film/substrate heterostructure is limited to the nanowatt scale to date,falling short of the practical application requirement.Here,we fabricated the CrN/SrTiO_(3-x) heterostructures with high thermoelectric output power and outstanding thermal stability.By varying the CrN film thickness and the reduction degree of CrN/SrTiO_(3-x) substrate,the optimized power output and the power density have respectively reached 276μWand 10^(8) mW/cm^(2) for the 30 nm CrN film on a highly reduced surface of CrN/SrTiO_(3-x) under a temperature difference of 300 K.The performance enhancement is attributed to the CrN/CrN/SrTiO_(3-x) heterointerface,corroborated by the band bending as revealed by the scanning Kelvin probe microscopy.These results will stimulate further research efforts towards interface thermoelectrics.Xueying Wan Xiaowei Lu Lin Sun Mingyu Chen Na Ta Wei Liu Qi Chen Liwei Chen Jian He Peng Jiang Xinhe Bao 2022Journal of Energy Chemistry2022,31,1:0
16Synthesis of pH-responsive triazine skeleton nano-polymer composite containing AIE group for drug delivery显示文摘We exploited a unique porous structure of the nano-covalent triazinepolymer(NCTP)containing aggregation-induced emission(AlE)group to achievecontrolled release and drug tracking in tumor acidic microenvironment.NCTP wassynthesized by the Friedel-Crafts alkylation and the McMurry coupling reaction.It notonly had strong doxorubicin(DOX)-loading capacity due to its high specific surface areaand large pore volume,but also showed the significant cumulative drug release as aresult of the pH response of triazine polymers.NCTP was induced luminescence aftermass accumulation near tumor cells.Besides,it had excellent biocompatibility andobvious antineoplastic toxicity.The results demonstrate that NCTP as a utility-type drugcarrier provides a new route for designing the multi-functional drug delivery platform.Yifan ZHANG Xueying PENG Xinbo JING Lin CUI Shengchao YANG Jianning WU Guihua MENG Zhiyong LIU Xuhong GUO 2021Frontiers of Materials Science2021,15,1:0
17Liposomalα-cyperone targeting bone resorption surfaces suppresses osteoclast differentiation and osteoporosis progression via the PI3K/Akt axis显示文摘Osteoporosis is a metabolic dysregulation of bone that occurs mainly in postmenopausal women,and the hyperfunction of osteoclasts is the primary contributor to postmenopausal osteoporosis.However,the development of effective therapeutic drugs and precise delivery systems remains a challenge in the field of anti-absorption therapy.Here,we reported theα-cyperone(α-CYP)for anti-osteoporosis and developed a liposome-based nano-drug delivery system ofα-CYP,that specifically targets the bone resorption interface.Firstly,we found that theα-CYP,one of the major sesquiterpenes of Cyperus rotundus L.,attenuated the progression of osteoporosis in ovariectomized(OVX)mice and down-regulated the expression of phosphorylated proteins of phosphoinositide 3-kinase(PI3K)and protein kinase B(Akt),causing down-regulation of osteoclast-related genes/proteins and curbing osteoclast differentiation.Furthermore,α-CYP reversed the activation of osteoclastic differentiation and enhanced osteoporosis-related proteins expression caused by PI3K/Akt agonist(YS-49).More importantly,we adopted the osteoclastic resorption surface targeting peptide Asp8 and constructed the liposome(lipαC@Asp8)to deliverα-CYP to osteoclasts and confirmed its anti-osteoporosis effect and enhanced osteoclast inhibition by blocking PI3K/Akt axis.In conclusion,this study demonstrated thatα-CYP inhibits osteoclast differentiation and osteoporosis development by silencing PI3K/Akt pathway,and the liposome targeting delivery systems loaded withα-CYP might provide a novel and effective strategy to treat osteoporosis.Lin Yang Xueying An Wang Gong Wenshu Wu Bin Liu Xiaoyan Shao Yansi Xian Rui Peng Baosheng Guo Qing Jiang 2024Nano Research2024,17,4:0
18Autologous exosome facilitates load and target delivery of bioactive peptides to repair spinal cord injury显示文摘Spinal cord injury(SCI)causes motor,sensory and automatic impairment due to rarely axon regeneration.Developing effective treatment for SCI in the clinic is extremely challenging because of the restrictive axonal regenerative ability and disconnection of neural elements after injury,as well as the limited systemic drug delivery efficiency caused by blood spinal cord barrier.To develop an effective non-invasive treatment strategy for SCI in clinic,we generated an autologous plasma exosome(AP-EXO)based biological scaffold where AP-EXO was loaded with neuron targeting peptide(RVG)and growth-facilitating peptides(ILP and ISP).This scaffold can be targeted delivered to neurons in the injured area and elicit robust axon regrowth across the lesion core to the levels over 30-fold greater than naïve treatment,thus reestablish the intraspinal circuits and promote motor functional recovery after spinal cord injury in mice.More importantly,in ex vivo,human plasma exosomes(HP-EXO)loaded with combinatory peptides of RVG,ILP and ISP showed safety and no liver and kidney toxicity in the application to nude SCI mice.Combining the efficacy and safety,the AP-EXO-based personalized treatment confers functional recovery after SCI and showed immense promising in biomedical applications in treating SCI.It is helpful to expand the application of combinatory peptides and human plasma derived autologous exosomes in promoting regeneration and recovery upon SCI treatment.Ning Ran Wenxiang Li Renjie Zhang Caorui Lin Jianping Zhang Zhijian Wei Zonghao Li Zhongze Yuan Min Wang Baoyou Fan Wenyuan Shen Xueying Li Hengxing Zhou Xue Yao Xiaohong Kong Shiqing Feng 2023Bioactive Materials2023,,7:0
19Protective mechanism of quercetin compounds against acrylamide-induced hepatotoxicity显示文摘Quercetin compounds have antioxidant,anti-inflammatory and anticancer pharmacological functions.Longterm exposure to acrylamide(AA)can cause liver injury and endanger human health.However,whether quercetin compounds can attenuate AA-induced liver injury and the specific mechanism are not clear.Here,we studied the mechanism and structure-activity relationship of quercetin compounds in reducing AA-induced hepatotoxicity in vivo and in vitro.In vivo studies found that quercetin-like compounds protect against AAinduced liver injury by reducing oxidative stress levels,activating the Akt/m TOR signaling pathway to attenuate autophagy,and improving mitochondrial apoptosis and endoplasmic reticulum stress-mediated apoptosis.In vitro studies found that quercetin compounds protected Hep G2 cells from AA by attenuating the activation of AA-induced autophagy,lowering reactive oxygen species(ROS)levels by exerting antioxidant effects and thus attenuating oxidative stress,increasing mitochondrial membrane potential(MMP),and improving apoptosis-related proteins,thus attenuating AA-induced apoptosis.Furthermore,the conformational differences between quercetin compounds correlated with their protective capacity against AA-induced hepatotoxicity,with quercetin showing the best protective capacity due to its strongest antioxidant activity.In conclusion,quercetin compounds can protect against AA-induced liver injury through multiple pathways of oxidative stress,autophagy and apoptosis,and their protective capacity correlates with antioxidant activity.Linzi Li Xueying Lei Lin Chen Ya Ma Jun Luo Xuebo Liu Xinglian Xu Guanghong Zhou Xianchao Feng 2024Food Science and Human Wellness2024,13,1:0
