Reconstruction of osteochondral(OC)defects represents an immense challenge due to the need for synchronous regeneration of special stratified tissues.The revolutionary innovation of bioprinting provides a robust method for precise fabrication of tissue-engineered OCs with hierarchical structure;however,their spatial living cues for simultaneous fulfilment of osteogenesis and chondrogenesis to reconstruct the cartilage-bone interface of OC are underappreciated.Here,inspired by natural OC bilayer features,anisotropic bicellular living hydrogels(ABLHs)simultaneously embedding articular cartilage progenitor cells(ACPCs)and bone mesenchymal stem cells(BMSCs)in stratified layers were precisely fabricated via two-channel extrusion bioprinting.The optimum formulation of the 7%GelMA/3%AlgMA hydrogel bioink was demonstrated,with excellent printability at room temperature and maintained high cell viability.Moreover,the chondrogenic ability of ACPCs and the osteogenic ability of BMSCs were demonstrated in vitro,confirming the inherent differential spatial regulation of ABLHs.

The scarcity of native periosteum poses a significant clinical barrier in the repair of critical-sized bone defects.The challenge of enhancing regenerative potential in bone healing is further compounded by oxidative stress at the fracture site.However,the introduction of artificial periosteum has demonstrated its ability to promote bone regeneration through the provision of appropriate mechanical support and controlled release of proosteogenic factors.In this study,a poly(L-lactic acid)(PLLA)/hyaluronic acid(HA)-based nanofibrous membrane was fabricated using the coaxial electrospinning technique.The incorporation of irisin into the core-shell structure of PLLA/HA nanofibers(PLLA/HA@Irisin)achieved its sustained release.In vitro experiments demonstrated that the PLLA/HA@Irisin membranes exhibited favorable biocompatibility.The osteogenic differentiation of bone marrow mesenchymal stem cells(BMMSCs)was improved by PLLA/HA@Irisin,as evidenced by a significant increase in alkaline phosphatase activity and matrix mineralization.Mechanistically,PLLA/HA@Irisin significantly enhanced the mitochondrial function of BMMSCs via the activation of the sirtuin 3 antioxidant pathway.To assess the therapeutic effectiveness,PLLA/HA@Irisin membranes were implanted in situ into critical-sized calvarial defects in rats.The results at 4 and 8 weeks post-surgery indicated that the implantation of PLLA/HA@Irisin exhibited superior efficacy in promoting vascularized bone formation,as demonstrated by the enhancement of bone matrix synthesis and the development of new blood vessels.The results of our study indicate that the electrospun PLLA/HA@Irisin nanofibers possess characteristics of a biomimetic periosteum,showing potential for effectively treating critical-sized bone defects by improving the mitochondrial function and maintaining redox homeostasis of BMMSCs.

The sudden onset of the coronavirus disease 2019(COVID-19)in January 2020 has affected essential global health services.Cancer-screening services that can reduce cancer mortality are strongly affected.However,the specific role of COVID-19 in cancer screening is not fully understood.This study aimed to assess the efficiency of global cancer screening programs before and during the COVID-19 pandemic and to promote potential cancer-screening strategies for the next pandemic.Electronic searches in PubMed,Embase,and Web of Science,and manual searches were performed between January 1,2020 and March 1,2023.Cohort studies that reported the number of participants who underwent cancer screening before and during the COVID-19 pandemic were included.The methodological quality of the included studies was assessed using the Newcastle-Ottawa Scale.Differences in cancer-screening rates were estimated using the incidence rate ratio(IRR).Fifty-five cohort studies were included in this meta-analysis.The screening rates of colorectal cancer using invasive screening methods(Pooled IRR=0.52,95%CI:0.42 to 0.65,p<0.01),cervical cancer(Pooled IRR=0.56,95%CI:0.47 to 0.67,p<0.01),breast cancer(Pooled IRR=0.57,95%CI:0.49 to 0.66,p<0.01)and prostate cancer(Pooled IRR=0.71,95%CI:0.56 to 0.90,p<0.01)during the COVID-19 pandemic were significantly lower than those before the COVID-19 pandemic.The screening rates of lung cancer(Pooled IRR=0.77,95%CI:0.58 to 1.03,p=0.08)and colorectal cancer using noninvasive screening methods(Pooled IRR=0.74,95%CI:0.50 to 1.09,p=0.13)were reduced with no statistical differences.The subgroup analyses revealed that the reduction in cancer-screening rates varied across economies.Our results suggest that the COVID-19 pandemic has had a noteworthy impact on colorectal,cervical,breast,and prostate cancer screening.Developing innovative cancer-screening technologies is important to promote the efficiency of cancer-screening services in the post-COVID-19 era and prepare for the next pandemic.

Repair of severe skin tissue injury remains a great challenge and wound infection is still a formidable problem.In this study,new macroporous and antibacterial gelatin/alginate(SAG)-based hydrogels for wound repair were designed and developed based on in-situ gas foaming method and ion release strategy as a result of Mg-Cu particles degradation in the hydrogel matrix.The addition of Mg-Cu particles decreased the storage modulus of SAG,maintained its mechanical resilience and enhanced its water-absorbing capability.Moreover,the water vapor transmission rate of SAG added with 2 wt.%Mg-Cu(SAG-2 MC)was 124%of that of medical gauze and 804%of commercial Tegaderm^(TM)film dressing.The bacterial inhibition rates of SAG-2 MC against S.aureus.E.coli and P.aeruginosa reached 99.9%±0.1%,98.7%±1.2%and 98.0%±0.7%,respectively,significantly greater than those of the SAG hydrogel and Mg particle-modified hydrogels.In addition,SAG-2 MC hydrogel was biocompatible and promoted cell migration.In vivo experiment results indicated that SAG-2 MC significantly accelerated the skin wound healing in murine model as demonstrated by higher epidermis thickness,more collagen deposition and enhanced angiogenesis compared with SAG-OMC,SAG-2 M and TegadermTM film.In summary,Mg-Cu particles have great potential to modulate the physiochemical and biological properties of SAG hydrogels.Mg-Cu particle-modified SAG hydrogels reveal significant promise in the treatment of severe skin wound or other soft tissue lesions.

Although hydrogels have demonstrated great potential as new wound dressing materials,their instability in shape and/or mechanical characteristics due to water loss or freezing remains a shortcoming for wound care application.Herein,a novel injectable organohydrogel(IOH)of physically crosslinked polyvinyl alco-hol/glycerol that possesses non-drying capability and high stability at low temperature was developed for wound care.IOH has a skin-like stiffness(G’,∼280 Pa),high injectability,self-healing capability,high water-vapor transmission rate,and bacterial inhibitory effect.IOH exhibits high shape and mechanical stabilities after curing at 37°C and 50%relative humidity for 7 days or after curing at-20°C for 1 day.In addition,glycerol in IOH enabled an efficient loading and release of water-insoluble curcumin,a well-known anti-bacterial and anti-inflammation drug.The curcumin-releasing IOH(Cur-IOH)demonstrated significantly enhanced anti-bacterial performance compared to IOH or curcumin-loading polyvinyl alco-hol hydrogel.More importantly,Cur-IOH could accelerate wound healing in a murine full-thickness skin defect wound model,revealing improved wound contraction,collagen deposition,angiogenesis,and epi-dermis formation.This study demonstrates the great potential of organohydrogel for the reparation of severe wounds and Cur-IOH as a new type of injectable wound healing material.

Recently,rechargeable aqueous zinc-based batteries using manganese oxide as the cathode(e.g.,MnO_(2))have gained attention due to their inherent safety,environmental friendliness,and low cost.Despite their potential,achieving high energy density in Zn||MnO_(2)batteries remains challenging,highlighting the need to understand the electrochemical reaction mechanisms underlying these batteries more deeply and optimize battery components,including electrodes and electrolytes.This review comprehensively summarizes the latest advancements for understanding the electrochemistry reaction mechanisms and designing electrodes and electrolytes for Zn||MnO_(2)batteries in mildly and strongly acidic environments.Furthermore,we highlight the key challenges hindering the extensive application of Zn||MnO_(2)batteries,including high-voltage requirements and areal capacity,and propose innovative solutions to overcome these challenges.We suggest that MnO_(2)/Mn^(2+)conversion in neutral electrolytes is a crucial aspect that needs to be addressed to achieve high-performance Zn||MnO_(2)batteries.These approaches could lead to breakthroughs in the future development of Zn||MnO_(2)batteries,off ering a more sustainable,costeff ective,and high-performance alternative to traditional batteries.

The application of photothermal therapy(PTT)is greatly limited by the low accumulation of photothermal agents,uneven photothermal distribution,and heat endurance of cancer cells.Worse still,despite PTT enhances immunogenicity,the anti-tumor immune efficacy is still unsatisfactory due to the inefficient immunogenic cell death(ICD)induction and poor infiltration of immune cells.To solve the above problems of PTT,we developed hyaluronic acid(HA)modified hollow copper sulfide nanoparticles encapsulating diethyldithiocarbamate(DDTC)to construct a breast tumor targeting and near infrared(NIR)photo-responsive drug delivery system(D-HCuS@HA),which further combined with losartan to improve the accumulation and penetration in the tumor site.Upon irradiation,D-HCuS@HA realized enhanced PTT and released cytotoxic Cu(DDTC)_(2)to eliminate heat endurance tumor cells,thereby enhancing antitumor effect and inducing effective ICD.Moreover,the combination with losartan could remodel the tumor microenvironment,allowing more T cells to infiltrate into the tumor,and significantly inhibiting the occurrence and development of metastatic tumors.In vitro/vivo results revealed the great potential of D-HCuS@HA combined with losartan,which provides a new paradigm for anti-tumor and anti-metastases.

Infected bone fractures remain a major clinical challenge for orthopedic surgeons.From a tissue regeneration perspective,biomaterial scaffolds with antibacterial and osteoinductive activities are highly desired,while advanced materials capable of mimicking the pathological microenvironment during the healing process of infected tissues remain an area deserving more research.Hematoma,the gel-like blood coagulum,plays an essential role in bone fracture repair because of its ability to serve as a dynamic and temporary scaffold with cytokines for both pathogen elimination and tissue healing.In light of this,we designed a dynamic hydrogel with hematoma-like antimicrobial or reparative performance for infected bone fracture repair in this study.The proposed dynamic hydrogel network was based on the reversible recognition of a natural glycopeptide antibiotic vancomycin(Van)and its target dipeptide D-Ala-D-Ala(AA),which could serve as a hematoma-like scaffold for obliterating bacteria in the fracture region and promoting bone repair by introducing an endogenous osteogenic peptide(OGP).In vivo experiments demonstrated that the hydrogel could rapidly eradicate bacteria,improve bone regeneration and restore the local inflammatory microenvironment.Together,findings from this study imply that the use of hematoma-like dynamic hydrogel could lead to a biomimetic revolution in surgical strategies against susceptible bone fractures.
