Myeloid-derived suppressor cells(MDSCs)are a group of heterogeneous immature cells with a strong immunosuppressive function in myeloid cells,which are impeded in the differentiation of myeloid cells under the pathological conditions of hypoxia,inflammation,infection,and cancer.As individuals age,there is a significant increase in myeloid-derived suppressor cells(MDSCs),which subsequently enhance the immunosuppressive functions of Tregs(regulatory T cells)and Bregs(regulatory B cells).Therefore,MDSC may be related to immune system remodeling,thereby preventing excessive lesions caused by aging.This indicates that MDSC could serve as a potent inducer of immune senescence.Immune senescence,characterized by immune dysfunction with aging,is closely linked to the onset of diseases like infections,pulmonary fibrosis,and tumors.To achieve the purpose of anti-aging by intervening in immune aging and slow down the occurrence and development of related diseases.Therefore,understanding the biological characteristics of MDSC and its role in immune aging is crucial for immunotherapy targeting MDSC.This article reviews the different roles of MDSC in immune aging and its relationship with pulmonary fibrosis,tumor and other related diseases to provide theoretical basis for more comprehensive targeted MDSC immunotherapy. 展开更多

Inflammatory bowel disease(IBD)represents a chronic inflammatory condition profoundly impacting the gastrointestinal tract.Its prevalence has markedly risen in both developed and developing nations over recent decades.Despite the absence of definitive etiological elucidation,therapeutic strategies predominantly revolve around pharmacological interventions aimed at symptom mitigation.Alginate(AG)is a polysaccharide of marine origin that has garnered significant attention due to its inherent biocompatibility,pH sensitivity,and cross-linking.Its exploration within drug delivery systems for IBD treatment stems from its natural sourcing,non-cytotoxic nature,and economic viability.Notably,AG demonstrates facile interpolymeric cross-linking,facilitating the formation of a cohesive network conducive to sustained drug release kinetics.AG-based carrier systems for sustained drug release,and targeted drug delivery have been widely studied.This article reviews the pathogenesis of IBD and the current drugs,AG-based drug delivery systems and their properties in alleviating IBD.The prospect of further development of AG in the field of biopharmaceutical and drug delivery is prospected. 展开更多

Background:Excessive exudate secreted from chronic wounds often leads to overhydration and infection.Although a variety of dressings are currently available in clinical applications,they frequently fail to provide multifunction to promote chronic wound healing.The dressings with a Janus structure,featuring distinct properties on each side,are potential to improve wound healing.Methods:Composite dressings with a Janus structure were fabricated,comprising freeze-dried polycaprolactone(PCL)electrospun membrane and alginate-based hydrogel.The PCL fibrous membrane provided air permeability,while the hydrogel loaded with Deferoxamine,composed of alginate and poly(N-isopropylacrylamide)(PNIPAM),exhibited hygroscopic properties.The inclusion of PNIPAM imparted thermo-responsivity.Results:The hydrogel(thickness of 2.778±0.082 mm)exhibited a robust adhesion to the fiber membrane(thickness of 0.261±0.041 mm).For ANDC(Alginate-PNIPAM hydrogel with Deferoxamine/PCL membrane)samples,the water vapor transmission rate(WVTR)was measured to be 3364.80±23.23 g∙m−2∙day−1 and the swelling ratio at 2 h was determined to be 1179±125%.The thermo-responsivity of ANDC samples manifested in an increased swelling rate,escalating from 797±189%at 37°C to 1132±147%at 4°C.The elastic modulus was assessed for lyophilized and rehydrated ANDC sample.When theωof the rheometer rotor was decreased from 10 rad/s to 0.1 rad/s,the lyophilized dressing exhibited a decrease from 2.65±0.01 MPa to 1.80±0.90 MPa,while the rehydrated dressing demonstrated an increase from 133.65±55.68 Pa to 264.23±141.71 Pa.The pro-healing properties of the dressings were evaluated using full-thickness skin defect model on SD rats,and a circular wound of diameter 10 mm healed completely by day 12.Conclusion:The dressings not only protected the wound and absorbed excess exudate,but also demonstrated nondestructive peelability upon cooling,providing a novel approach for accelerating wound healing and management. 展开更多

Soft tissue repair and regeneration present a significant clinical challenge.Soft hydrogels have emerged as a promising solution for promoting stem cell differentiation and facilitating soft tissue formation[1].Various materials,including synthetic polymers like polydimethyl siloxane and natural polymers like proteins,have been be used as hydrogel matrix for hydrogel preparation[2,3].However,the limited biodegradability,inhomogeneous network structure,and inadequate mechanical properties of these hydrogels hinder their long-term application in complex environments in vivo.Inspired by the nanostructure of collagen fibrils,Li et al.developed a strategy for creating injectable nanofibrillar hydrogels by combining self-assembly and chemical crosslinking of nanoparticles[4].Moreover,injectable hydrogels offer advantages as implantable materials,including better defect filling and reduced risk of infection compared to prefabricated hydrogels[5]. 展开更多

Wound healing is a critical physiological process in living organisms that includes repair cell proliferation and migration,etc.[1,2].While effective wound-healing treatment strategies have been developed in the past,few have actively controlled the behavior of skin cells to accelerate wound healing[3,4].The importance of accelerated wound healing lies in its ability to shorten treatment time,reduce the risk of infection,and lower the cost of treatment.Electrical stimulation can modulate cell behavior during wound healing by simulating endogenous electric fields,boosting cell migration,fibroblast proliferation,and granulation tissue growth more significantly than traditional methods[5-7].However,electrical stimulation devices’size,space limitations,and unsustainability make them challenging to use in clinical surgery,hindering real-time and convenient treatment.It is therefore crucial to explore the miniaturization of electrical stimulation devices to advance the healing of skin wounds in clinical procedures.Recently,Chen et al.report a flexible micro-Zn-MnO2(mZMB)battery-based woundplast for wound management,which shows a promising path in biomedical applications(Figure 1)[8]. 展开更多

This study comprehensively analyzes the status,characteristics,focal points,and evolving trends of global research on“stroke risk analysis”over the past four years(2020–2023),aiming to provide insights for directing future research endeavors.By utilizing the Newcastle-Ottawa Scale,63 high-quality research papers were selected and subjected to a systematic literature review.In terms of research methods,stroke risk analysis research has evolved from clinical trials(e.g.,establishing control groups,using authoritative scales)towards statistical and data analysis methods(e.g.,decision tree analysis).Regarding research factors,early studies primarily focused on pathological factors associated with hemorrhagic and ischemic stroke,such as hypertension,hyperlipidemia,and diabetes.Recent research from the past two years indicates a shift towards emerging factors,including temperature conditions,air quality,and Corona Virus Disease 2019(COVID-19).In terms of application domains,stroke research covers a broad range of fields but mainly focuses on exploring risk factors,interventions during diagnosis and treatment stages,and rehabilitation,with clinical diagnosis,treatment,and drug intervention studies being predominant.While the research landscape is becoming increasingly diversified and comprehensive,there remains a need for more comprehensive and in-depth studies on novel topics,as well as integrated applications of research methods,presenting ample opportunities for exploring dependent variables in future stroke. 展开更多

Background:The Taylor Spatial Frame(TSF)has gained popularity among orthopedic surgeons for treating open fractures.However,a key challenge is the timely and safe removal of the frame.This study assessed the efficacy and safety of axial load-share ratio(ALSR)testing to evaluate callus healing strength after TSF treatment of open tibial fractures.Methods:A retrospective case-control study was conducted,analyzing 180 adult patients with open tibial fractures treated at Tianjin Hospital’s Orthopedic Limb Correction Unit between August 2019 and August 2022.All patients underwent TSF external fixation surgery,and were divided into two groups based on ALSR testing.Group I(92 patients)underwent ALSR testing,with frame removal if the test value fell below 5%.Traditional methods were used for fixator removal guidance in Group II(88 patients).Clinical outcomes,including fixation duration,complications after fixator removal,and Johner-Wruhs functional scores,were compared between the two groups.Results:The groups showed no statistically significant differences(P>0.05)in sex,age,injury side,body mass index,surgery timing,or fracture type.Group I had a significantly shorter fixation duration(25.85±5.57 weeks)compared to Group II(31.82±6.98 weeks)(P<0.05).Following fixator removal,Group I demonstrated superior Johner-Wruhs scores compared to Group II,indicating better outcomes(P<0.05).Complication rates did not differ significantly between the groups at the last follow-up(P>0.05).Conclusion:Regular postoperative ALSR testing could safely and effectively guide TSF removal following open tibial fracture treatment.This method significantly reduced fixation duration compared to traditional guidance methods while maintaining efficacy and safety. 展开更多

The limited amount of data in the healthcare domain and the necessity of training samples for increased performance of deep learning models is a recurrent challenge,especially in medical imaging.Newborn Solutions aims to enhance its non-invasive white blood cell counting device,Neosonics,by creating synthetic in vitro ultrasound images to facilitate a more efficient image generation process.This study addresses the data scarcity issue by designing and evaluating a continuous scalar conditional Generative Adversarial Network(GAN)to augment in vitro peritoneal dialysis ultrasound images,increasing both the volume and variability of training samples.The developed GAN architecture incorporates novel design features:varying kernel sizes in the generator’s transposed convolutional layers and a latent intermediate space,projecting noise and condition values for enhanced image resolution and specificity.The experimental results show that the GAN successfully generated diverse images of high visual quality,closely resembling real ultrasound samples.While visual results were promising,the use of GAN-based data augmentation did not consistently improve the performance of an image regressor in distinguishing features specific to varied white blood cell concentrations.Ultimately,while this continuous scalar conditional GAN model made strides in generating realistic images,further work is needed to achieve consistent gains in regression tasks,aiming for robust model generalization. 展开更多

Background:Both simvastatin and metformin have demonstrated potential efficacy in osteoporosis(OP)treatment.However,there is a lack of systematic studies comparing their anti-osteoporotic effects.This study aims to compare the effects of simvastatin and metformin on OP through Mendelian randomization(MR)studies and animal experiments.Methods:Initially,we will analyze the causal impact of simvastatin or metformin treatment on OP prevalence and three common clinical OP diagnostic markers(bone mineral density(BMD),serum osteocalcin(OCN),and tartrate-resistant acid phosphatase(TRAP)levels)using genome-wide association study(GWAS)summary statistics.Additionally,we established animal models to further analyze and compare the anti-osteoporosis effects of simvastatin and metformin.8 male C57BL/6J mice(3-month-old)and 24 male C57BL/6J mice(18-month-old)were treated with simvastatin or metformin for 12 weeks.OP pathology was assessed using histology,immunohistochemistry,biomechanical tests,micro-computed tomography,and osteogenic differentiation assays.Results:In the MR analysis,metformin treatment was significantly associated with lower OP prevalence(OR(95%CI)=0.933(0.902–0.965),β=-0.0694,P<0.001)and higher BMD(OR(95%CI)=3.719(1.750–7.908),β=1.3136,P<0.001).In the animal experiment,both drugs increased bone mass,improved bone microstructure,and promoted osteoblast differentiation.However,metformin appeared more effective in several aspects.It significantly inhibited bone marrow adipocyte and osteoclast differentiation in aged mice compared to simvastatin.Additionally,metformin better promoted the expression of osteoprotegerin(OPG)and collagen type I(Col-I)in bone tissue and maintained the structure and biomechanical properties of cancellous bone.Conclusion:Both drugs significantly preserved bone homeostasis.Particularly,compared with simvastatin,metformin exhibited superior effects in inhibiting adipogenesis,enhancing the OPG/RANKL pathway,and promoting cancellous bone reconstruction.Metformin may serve as a valuabl 展开更多
