Polymer-based composite electrolytes composed of three-dimensional Li_(6.4)La_(3)Zr_(2)Al_(0.2)O_(12)(3D-LLZAO)have attracted increasing attention due to their continuous ion conduction and satisfactory mechanical properties.However,the organic/inorganic interface is incompatible,resulting in slow lithium-ion transport at the interface.Therefore,the compatibility of organic/inorganic interface is an urgent problem to be solved.Inspired by the concept of“gecko eaves”,polymer-based composite solid electrolytes with dense interface structures were designed.The bridging of organic/inorganic interfaces was established by introducing silane coupling agent(3-chloropropyl)trimethoxysilane(CTMS)into the PEO-3D-LLZAO(PL)electrolyte.The in-situ coupling reaction improves the interface affinity,strengthens the organic/inorganic interaction,reduces the interface resistance,and thus achieves an efficient interface ion transport network.The prepared PEO-3D-LLZAO-CTMS(PLC)electrolyte exhibits enhanced ionic conductivity of 6.04×10^(-4)S cm^(-1)and high ion migration number(0.61)at 60℃and broadens the electrochemical window(5.1 V).At the same time,the PLC electrolyte has good thermal stability and high mechanical properties.Moreover,the Li Fe PO_(4)|PLC|Li battery has excellent rate performance and cycling stability with a capacity decay rate of 2.2%after 100 cycles at 60℃and 0.1 C.These advantages of PLC membranes indicate that this design approach is indeed practical,and the in-situ coupling method provides a new approach to address interface compatibility issues.

The accumulation of heavy metals in mushrooms has presented a significant risk to human health， underscoring the importance of devising a portable and cost-effective method for detecting heavy metals. Thus， we have developed an electrochemical sensor based on 3-dimensional highly reduced graphene oxide (3D-HRGO) in conjunction with Fe3O4nanoparticles， enabling the simultaneous quantification of Cd2+， Pb2+， Cu2+， and Hg2+. The 3D-HRGO/Fe3O4nano-particles material prepared in this study was characterized and confirmed by multiple techniques， then dispersed in a simple and environmental dispersant， consist of 75% ethanol and 0.1% Nafion， and coating on a glass carbon electrode (GCE) to preparing a 3D-HRGO/Fe3O4/GCE sensor. The limit of detection (LOD) of 3D-HRGO/Fe3O4/GCE sensor for Cd2+， Pb2+， Cu2+， and Hg2+in simultaneous detection were 0.2 μg/L， 0.6 μg/L， 0.6 μg/L， and 0.9 μg/L， respectively. The sensor demonstrates exceptional stability， reproducibility， anti-interference， and recovery rate. Furthermore， the electrochemical sensor was employed to detect heavy metals in actual mushrooms and validated through conventional methodologies. This study represents the pioneering utilization of 3D-HRGO/Fe3O4as a foundational material for an electrochemical sensor capable of simultaneous detection of multiple metals， thereby advancing the progress of on-site and expeditious detection techniques.

Data-independent acquisition(DIA)technology for protein identification from mass spectrometry and related algorithms is developing rapidly.The spectrum-centric analysis of DIA data without the use of spectra library from data-dependent acquisition data represents a promising direction.In this paper,we proposed an untargeted analysis method,Dear-DIA^(XMBD),for direct analysis of DIA data.Dear-DIA^(XMBD) first integrates the deep variational autoencoder and triplet loss to learn the representations of the extracted fragment ion chromatograms,then uses the k-means clustering algorithm to aggregate fragments with similar representations into the same classes,and finally establishes the inverted index tables to determine the precursors of fragment clusters between precursors and peptides and between fragments and peptides.We show that Dear-DIA^(XMBD) performs superiorly with the highly complicated DIA data of different species obtained by different instrument platforms.

Owing to the function of manipulating light absorption distribution,tandem organic solar cells containing multiple sub-cells exhibit high power conversion efficiencies.However,there is a substantial challenge in precisely controlling the inter-subcells carrier migration which determines the balance of charge transport across the entire device.The conductivity of"nanowires"-like conducting channel in interconnecting layer between sub-cells should be improved which calls for fine engineering on the morphology of polyelectrolyte in interconnecting layer.Here,we develop a simple method to effectively manipulating the domains of conductive components in commercially available polyelectrolyte PEDOT:PSs.The use of poor solvent could effectively modify the configuration of polystyrene sulfonic acid and thus the space for conductive components.Based on our strategy,the insulated shells wrapping conductive domains are thinned and the efficiencies of tandem organic solar cells are improved.We believe our method might provide guidance for the manufacture of tandem organic solar cells.

The skeletal system,which contains bones,joints,tendons,ligaments and other elements,plays a wide variety of roles in body shaping,support and movement,protection of internal organs,production of blood cells and regulation of calcium and phosphate metabolism.The prevalence of skeletal diseases and disorders,such as osteoporosis and bone fracture,osteoarthritis,rheumatoid arthritis,and intervertebral disc degeneration,increases with age,causing pain and loss of mobility and creating a huge social and economic burden globally.Focal adhesions(FAs)are macromolecular assemblies that are composed of the extracellular matrix(ECM),integrins,intracellular cytoskeleton and other proteins,including kindlin,talin,vinculin,paxillin,pinch,Src,focal adhesion kinase(FAK)and integrin-linked protein kinase(ILK)and other proteins.FA acts as a mechanical linkage connecting the ECM and cytoskeleton and plays a key role in mediating cell–environment communications and modulates important processes,such as cell attachment,spreading,migration,differentiation and mechanotransduction,in different cells in skeletal system by impacting distinct outside-in and inside-out signaling pathways.This review aims to integrate the up-to-date knowledge of the roles of FA proteins in the health and disease of skeletal system and focuses on the specific molecular mechanisms and underlying therapeutic targets for skeletal diseases.

Osteoarthritis(OA)is a chronic degenerative joint disorder that leads to disability and affects more than 500 million population worldwide.OA was believed to be caused by the wearing and tearing of articular cartilage,but it is now more commonly referred to as a chronic whole-joint disorder that is initiated with biochemical and cellular alterations in the synovial joint tissues,which leads to the histological and structural changes of the joint and ends up with the whole tissue dysfunction.Currently,there is no cure for OA,partly due to a lack of comprehensive understanding of the pathological mechanism of the initiation and progression of the disease.Therefore,a better understanding of pathological signaling pathways and key molecules involved in OA pathogenesis is crucial for therapeutic target design and drug development.In this review,we first summarize the epidemiology of OA,including its prevalence,incidence and burdens,and OA risk factors.We then focus on the roles and regulation of the pathological signaling pathways,such as Wnt/β-catenin,NF-κB,focal adhesion,HIFs,TGFβ/ΒΜP and FGF signaling pathways,and key regulators AMPK,mTOR,and RUNX2 in the onset and development of OA.In addition,the roles of factors associated with OA,including MMPs,ADAMTS/ADAMs,and PRG4,are discussed in detail.Finally,we provide updates on the current clinical therapies and clinical trials of biological treatments and drugs for OA.Research advances in basic knowledge of articular cartilage biology and OA pathogenesis will have a significant impact and translational value in developing OA therapeutic strategies.

Dear editor,The comorbidity of obesity and osteoporosis illustrates the communication and coordination of adipose and bone tissues.Leptin and adiponectin derived from adipocytes regulate osteoblast formation and function to impact bone mass through direct and indirect mechanisms.1 It is known that bone marrow adipocytes(BMA)can control bone mass by modulating the bone morphogenetic protein(BMP)and other signaling pathways.BMAs can secret soluble factors,which impact osteoblasts,osteoclasts,and osteocytes.2 Sclerostin is a potent inhibitor of bone acquisition that antagonizes Wnt/β-catenin signaling.

Photodynamic therapy(PDT)is an important technique to deal with drug-resistant bacterial infections in the post-antibiotic era.However,the hypoxic environment in intractable infections such as refractory keratitis and periodontitis,makes PDT more difficult.In this work,spontaneous oxygen-producing cyanobacteria were used as the carrier of photosensitizer(Ce6),and ultrasmall Cu_(5.4)O nanoparticles(Cu_(5.4)O USNPs)with catalase activity for infection and inflammation elimination and rapid tissue repair(CeCycn-Cu_(5.4)O).The loading of Ce6 and Cu_(5.4)O USNPs onto cyanobacteria surface were confirmed by transmission electron microscopy,nano particle size analyzer,scanning electron microscopy.In vitro sterilization and biofilm removal experiments demonstrated that the restriction of hypoxic environment to PDT was significantly alleviated due to the oxygen production of cyanobacteria.Under laser irradiation,the close transfer of energy photons to oxygen produced by cyanobacteria reduced more than 90% of Ce6 dosages(660 nm,200 mW/cm^(2),2 min).It is worth mentioning that both rapid sterilization through PDT and long-term oxidized free radicals elimination were achieved by adjusting the ratio of Ce6 and Cu_(5.4)O USNPs.Both periodontitis and refractory keratitis animal models proved the excellent self-oxygenation enhanced antibacterial property and promotion of tissue repair.

Bioactive Materials 2021年第8期6卷 2372-2389页

Cartilage-targeting delivery of therapeutic agents is still an effective strategy for osteoarthritis(OA)therapy.Recently,scavenging for reactive oxygen species(ROS)and activating autophagy have been increasingly reported to treat OA effectively.In this study,we designed,for the first time,a dual-drug delivery system based on metal organic framework(MOF)-decorated mesoporous polydopamine(MPDA)which composed of rapamycin(Rap)loaded into the mesopores and bilirubin(Br)loaded onto the shell of MOF.The collagen II-targeting peptide(WYRGRL)was then conjugated on the surface of above nanocarrier to develop a cartilage-targeting dual-drug delivery nanoplatform(RB@MPMW).Our results indicated the sequential release of two agents from RB@MPMW could be achieved via near-infrared(NIR)laser irritation.Briefly,the rapid release of Br from the MOF shell exhibited excellent ROS scavenging ability and anti-apoptosis effects,however responsively reduced autophagy activity,to a certain extent.Meanwhile,following the NIR irradiation,Rap was rapidly released from MPDA core and further enhanced autophagy activation and chondrocyte protection.RB@MPMW continuously phosphorylated AMPK and further rescued mitochondrial energy metabolism of chondrocytes following IL-1βstimulation via activating SIRT1-PGC-1αsignaling pathway.Additionally,the cartilage-targeting property of peptide-modified nanocarrier could be monitored via Magnetic Resonance(MR)and IVIS imaging.More significantly,RB@MPMW effectively delayed cartilage degeneration in ACLT rat model.Overall,our findings indicated that the as-prepared dual-drug delivery nanoplatform exerted potent anti-inflammation and anti-apoptotic effects,rescued energy metabolism of chondrocytes in vitro and prevented cartilage degeneration in vivo,which thereby showed positive performance for OA therapy.
