    查看更多>>摘要：Satisfactory ionic conductivity,excellent mechanical stability,and high-temperature resistance are the prerequisites for the safe application of solid polymer electrolytes(SPEs)in all-solid-state lithium metal batteries(ASSLMBs).In this study,a novel poly(m-phenylene isophthalamide)(PMIA)-core/poly(ethylene oxide)(PEO)-shell nanofiber membrane and the functional Li6.4La3Zr1.4Ta0.6O12(LLZTO)ceramic nanopar-ticle are simultaneously introduced into the PEO-based SPEs to prepare composite polymer electrolytes(CPEs).The core PMIA layer of composite nanofibers can greatly improve the mechanical strength and thermal stability of the CPEs,while the shell PEO layer can provide the 3D continuous transport channels for lithium ions.In addition,the introduction of functional LLZTO nanoparticle not only reduces the crys-tallinity of PEO,but also promotes the dissociation of lithium salts and releases more Li+ions through its interaction with the Lewis acid-base of anions,thereby overall improving the transport of lithium ions.Consequently,the optimized CPEs present high ionic conductivity of 1.38 ×10-4 S/cm at 30 ℃,signifi-cantly improved mechanical strength(8.5 MPa),remarkable thermal stability(without obvious shrinkage at 150 ℃),and conspicuous Li dendrites blocking ability(＞1800 h).The CPEs also both have good com-patibility and cyclic stability with LiFePO4(＞2000 cycles)and high-voltage LiNi0.8Mn0.1Co0.1O2(NMC811)(＞500 cycles)cathodes.In addition,even at low temperature(40℃),the assembled LiFePO4/CPEs/Li bat-tery still can cycle stably.The novel design can provide an effective way to exploit high-performance solid-state electrolytes.

    433-436页
    查看更多>>摘要：Sulphur(S)-template method based on conventional slurry-casting method has been developed to pro-duce porous silicon(Si)electrodes.The facile fabrication technology is suitable for current production line and expected to be widely applied to various electrode materials under large volume change during operation.Specifically,S particles as template agent are mixed with active material Si,carbon conductor and binder forming uniform slurry.After casting and drying,the electrodes are immersed in carbon disul-fide solution to remove S particles rapidly,generating pores in-situ at the original position of S particles.Electrochemical analysis shows that the pores inside electrodes are able to shorten lithium ion diffusion paths,reduce normal expansion rate and decrease formation of cracks in the Si electrode(2 mgsi/cm2),demonstrating a reversible capacity of 951 mAh/g at 0.5 A/g after 100 cycles(with a capacity retention of 99.5％)and a capacity of～826 mAh/g at 2 A/g.

    437-442页
    查看更多>>摘要：Facile and efficient method for constructing carbon dots(CDs)with narrow full width at half maximum(FWHM)is a major challenge in the field,and researches on regulating the FWHM of CDs are also rare and scarce.In this work,we delved into the synthesis of CDs with narrow fluorescence emission FWHM(NFEF-CDs)in the m-phenylenediamine(m-PD)/ethanol system,utilizing solid superacid resin as cata-lyst with solvothermal method.The resulting NFEF-CDs exhibit a photoluminescent(PL)emission peak at 521 nm with a narrow FWHM of 41 nm,an absolute PL quantum yield(QY)of 80％,and display excitation-independent PL behavior.Through comprehensive characterization,we identified the protonation of edge amino on NFEF-CDs as the key factor in achieving the narrow FWHM.Subsequently,we validated the broad applicability of solid superacid resins as catalysts for synthesizing CDs with narrow FWHM in the m-PD/ethanol system.Finally,we utilized a self-leveling method to prepare NFEF-CDs film on the surface of poly(methyl methacrylate)(PMMA)substrate and investigated the solid-state fluorescence properties of NFEF-CDs as well as their performance as luminescence solar concentrator(LSC)for photovoltaic conver-sion.The results revealed that the as-prepared LSC exhibit an internal quantum efficiency(ηint)of 42.39％and an optical efficiency(ηopt)of 0.68％.These findings demonstrate the promising prospects of NFEF-CDs in the field of LSCs and provide a theoretical basis for their application in photovoltaic conversion.

    Redox responsive polymeric nanoparticles enhance the efficacy of cyclin dependent kinase 7 inhibitor for enhanced treatment of prostate cancer

    Yiran TaoChunlei DaiZhaoxiang XieXinru You...
    443-448页
    查看更多>>摘要：Traditional therapies such as surgery and endocrine therapy no longer meet the clinical needs in prostate cancer treatment,and more effective treatments are urgently required.Recent studies have reported that targeted inhibition of the transcription factor cyclin dependent kinase 7(CDK7)could effectively suppress prostate cancer progression.However,the toxicity of CDK7 inhibitors such as THZ1 is the main limitation of the clinical application.In this work,we synthesized Cys8E(C8E)nanoparticles(NPs)loaded with THZ1(C8E@THZ1),a novel GSH-targeting and stimuli-responsive nano-delivery platform,and investigated its anti-tumor potential and biosafety properties.In vitro,C8E@THZ1 potently inhibited the proliferation and promoted the apoptosis of prostate cancer cells.On tumor-bearing mice,C8E@THZ1 inhibited tumors by up to 85％,while the damage of THZ1 to liver function was effectively avoided.These results confirmed that inhibition of CDK7 can effectively block the progression of prostate cancer,and that Cys8E NPs is a highly prospective delivery platform to promote the clinical application of CDK7 inhibitors.

    COX-2 blocking therapy in cisplatin chemosensitization of ovarian cancer:An allicin-based nanomedicine approach

    Huijiao FuPeiqin LiangQianwen ChenYan Wang...
    449-454页
    查看更多>>摘要：Recently,the utilization of nonsteroidal anti-inflammatory drugs(NSAIDs)to sensitize cisplatin(CDDP)has gained substantial traction in the treatment of ovarian cancer(OC).However,even widely employed NSAIDs such as celecoxib and naproxen carry an elevated risk of cardiovascular events,notably throm-bosis.Furthermore,the diminished sensitivity to CDDP therapy in OC is multifactorial,rendering the ap-plication of NSAIDs only partially effective due to their cyclooxygenase-2(COX-2)inhibiting mechanism.Hence,in this study,reactive oxygen species(ROS)-responsive composite nano-hydrangeas loaded with the Chinese medicine small molecule allicin and platinum(IV)prodrug(DTP@AP NPs)were prepared to achieve comprehensive chemosensitization.On one front,allicin achieved COX-2 blocking therapy,en-compassing the inhibition of proliferation,angiogenesis and endothelial mesenchymal transition(EMT),thereby mitigating the adverse impacts of CDDP chemotherapy.Simultaneously,synergistic chemosensi-tization was achieved from multifaceted mechanisms by decreasing CDDP inactivation,damaging mito-chondria and inhibiting DNA repair.In essence,these findings provided an optimized approach for syner-gizing CDDP with COX-2 inhibitors,offering a promising avenue for enhancing OC treatment outcomes.

    455-459页
    查看更多>>摘要：Essential amino acids(EAAs)deprivation is a potential antitumor approach because EAAs are critical for tumor growth.To efficiently inhibit tumor growth,continuous deprivation of EAAs is required,how-ever,continuous deprivation without precise control will introduce toxicity to normal cells.Herein,a programmable double-unlock nanocomplex(ROCK)was prepared,which could self-supply phenylalanine ammonia-lyase(PAL)to tumor cells for phenylalanine(Phe)deprivation.ROCK was double-locked in physiological conditions when administered systemically.While ROCK actively targeted to tumor cells by integrin αvβ3/5 and CD44,ROCK was firstly unlocked by cleavage of protease on tumor cell membrane,exposing CendR and R8 to enhance endocytosis.Then,hyaluronic acid was digested by hyaluronidase overexpressed in endo/lysosome of tumor cells,in which ROCK was secondly unlocked,resulting in pro-moting endo/lysosome escape and PAL plasmid(pPAL)release.Released pPAL could sustainably express PAL in host tumor cells until the self-supplied PAL precisely and successfully deprived Phe,thereby block-ing the protein synthesis and killing tumor cells specifically.Overall,our precise Phe deprivation strategy effectively inhibited tumor growth with no observable toxicity to normal cells,providing new insights to efficiently remove intratumoral nutrition for cancer therapy.

    Cocktail effect of ionic patch driven by triboelectric nanogenerator for diabetic wound healing

    Yixia ZhangCaili XueYunpeng ZhangQi Zhang...
    460-465页
    查看更多>>摘要：There is increasing evidence shows that either electrical stimulation(ES)or metal ion is an effective way to accelerate ulcerative wound healing.However,less attention is paid to investigating the synergistic effect between them.Herein,we explore the combined effects of ES and multiple metal ions on dia-betic wound healing assisted by a triboelectric nanogenerator(TENG).Firstly,the novel Eggshell@CuFe2O4 nanocomposites(NCs)are prepared,which show unique structure and intrinsic antimicrobial properties.Subsequently,the as-prepared nanocomposites are embedded in oxidized starch hydrogel to form a mul-tifunctional composite gel,which is further assembled into a wearable ionic triboelectric nanogenerator(iTENG)patch with polydimethylsiloxane(PDMS).It can convert the mechanical energy produced by a human body motion to electric energy and mediate the sequential release of metal ions(Fe2+/Ca2+/Cu2+),thereby resulting in the"cocktail effect"on impaired tissue.Under their effects,a satisfying healing re-sult in diabetic mouse is identified,which can effectively accelerate wound healing process by relieving inflammation,promoting angiogenesis and collagen deposition.The work puts forward the cocktail effect of electric simulation coupled with the multiple metal ions,and opens up a new perspective in designing iTENG patch towards repair of hard-to-heal wounds.

    Yuxin TianMengjun LiYang YangChunhui Li...
    466-470页
    查看更多>>摘要：The monkeypox virus(MPXV)outbreak,declared a Public Health Emergency of International Concern(PHEIC)by the World Health Organization(WHO)in 2022,continues to pose a significant threat due to the absence of vaccines or drugs for MPXV infection.In this study,we developed an mRNA vaccine that expressing the A29L antigen,a specific protein of the intracellular mature virus.Our vaccine utilizes a thermostable ionizable lipid nanoparticle(iLNP)platform and has been administered to mice.Our find-ings demonstrate that the MPXV A29L mRNA vaccine candidate induces robust cross-neutralizing immune responses against both vaccinia virus(VACV)and MPXV live virus.Furthermore,immunization with the vaccine candidate provided protection against the VACV challenge in mice.These findings underscore the potential of mRNA-LNP vaccines as safe and effective candidates against monkeypox epidemics.Given the current absence of specific interventions for MPXV infection,our study represents a significant step forward in developing a viable solution to combat this ongoing public health threat.

    Inhalation of taraxasterol loaded mixed micelles for the treatment of idiopathic pulmonary fibrosis

    Tong ZhangChao SunShubin YangZimin Cai...
    475-480页
    查看更多>>摘要：Idiopathic pulmonary fibrosis(IPF)is a chronic and fatal lung disease characterized by pulmonary inflam-mation,oxidative stress,and excessive extracellular matrix(ECM)deposition.Current anti-fibrotic drugs for IPF treatment in the clinic lack selectivity and demonstrate unsatisfactory efficacy,highlighting the urgent necessity for a novel therapeutic strategy.Taraxasterol(TA),which has biological activities against lung injury induced by various factors,is a potential anti-IPF drug due to its anti-inflammatory,antiox-idant and lung-protective effects.However,the protective effect of TA on IPF has not been confirmed,and its clinical application is limited due to its poor aqueous solubility.In this study,we demonstrated that TA could inhibit epithelial-mesenchymal transition(EMT)and migration of A549 cells by inhibiting the transforming growth factor-β1(TGF-β1)/Smad signaling pathway.To improve the aqueous solubility and pulmonary administration performance of TA,we prepared TA loaded methoxy poly(ethylene glycol)-poly(D,L-lactide)(mPEG-PLA)/D-α-tocopheryl polyethylene glycol succinate(TPGS)mixed polymeric mi-celles(TA-PM).Then a MicroSprayer® Aerosolizer was used to deliver TA-PM once every two days for three weeks to evaluate their therapeutic effects on bleomycin(BLM)-induced IPF mice.Our results demonstrated that inhaled TA-PM significantly inhibited BLM-induced inflammation,oxidative stress and fibrosis in lung tissue.Furthermore,TA-PM exhibited high pulmonary deposition and retention by pul-monary administration,along with a favorable safety profile.Overall,this study emphasizes the potential of inhaled TA-PM as a promising treatment for IPF,providing a new opportunity for their clinical appli-cation.
