Managing inflammatory bowel disease(IBD)is becoming increasingly complex and personalized,considering the advent of new advanced therapies with distinct mechanisms of action.Achieving mucosal healing(MH)is a pivotal therapeutic goal in IBD management and can prevent IBD progression and reduce flares,hospitalization,surgery,intestinal damage,and colorectal cancer.Employing proactive disease and therapy assessment is essential to achieve better control of intestinal inflammation,even if subclinical,to alter the natural course of IBD.Periodic monitoring of fecal calprotectin(FC)levels and interval endoscopic evaluations are cornerstones for evaluating response/remission to advanced therapies targeting IBD,assessing MH,and detecting subclinical recurrence.Here,we comment on the article by Ishida et al Moreover,this editorial aimed to review the role of FC and endoscopic scores in predicting MH in patients with IBD.Furthermore,we intend to present some evidence on the role of these markers in future targets,such as histological and transmural healing.Additional prospective multicenter studies with a stricter MH criterion,standardized endoscopic and histopathological analyses,and virtual chromoscopy,potentially including artificial intelligence and other biomarkers,are desired. 展开更多

Diabetic patients who underwent long-term dialysis may increase the prevalence of foot ulceration. In addition, diabetic foot ulcer (DFUs) patients with end-stage renal disease (ESRD) do not heal well, and the amputation rate is 6.5 - 10 times higher compared to the non-nephropathic diabetic population. Thus, a suitable therapeutic agent was needed. ON101 is a topical cream that promotes diabetic wound healing through a unique macrophage-regulating ability. In this case series, we included 5 diabetes patients (mean age 54.6 ± 8.7 years, 4 mal) with ESRD (mean eGFR 7.4 ± 3.35 mL/min/1.73m<sup>2</sup>) and had experienced dialysis for at least 4.5 years. These patients also have UT (University of Texas) grade 2A DFUs that have existed for at least 1.5 months (mean ulcer duration 8.3 ± 8.97 months). These subjects were applied ON101 twice daily for up to 20 weeks, and wound size was recorded during treatment. Among these subjects, three ulcers (patient No. 1, 2, and 3) completely healed within 10 weeks upon ON101 application, and one ulcer was 99% reduced at 20<sup>th</sup> weeks (patient No. 4). Only one ulcer didn’t show an obvious response that may due to poor compliance in wound care and glucose control. In summary, the overall healing rate was 60%, suggesting ON101 performed equivalence healing efficacy in dialysis patients compared with those who did not have dialysis. 展开更多

Mechanical as well as durability properties are pivotal for any type of concrete which gets adversely affected due to cracks that may form due to loading beyond its capacity.Concrete has the intrinsic property to heal itself to some extent but not fully as the passive form of autogenous healing plays an inferior role for a complete repair of a cementitious material.The self-healing capabilities can be enhanced by adding chemical admixtures,polymers,and bacteria strains induced calcium carbonate precipitation,etc.In this paper,the advancements in the development and performance of self-healing concrete using chemical admixtures,polymers,and bacteria strains are reviewed.This systematic review includes the available experimental tests and methodologies investigating self-healing efficiency over the last decade.Further,this review focussed on self-healing materials,the ideology,and opinions of those in the construction field on the direction of self-healing concrete for future applications.It is yet not possible to predict the most appropriate technique,however,a generalized opinion about the effectiveness of the different approaches has been illustrated. 展开更多

Skin is one of the most vulnerable tissues,but there is a lack of injectable bioactive hydrogel dressings,which possess high strength,antiswelling capacity,and wet tissue adhesiveness,but also a rapid gelling process to enable rapid hemostasis,sutureless wound closure,and scarless healing of infected skin wounds[1e5].A new injectable,antibacterial,and multifunctional hydrogel dressings based on poly(citric acid-co-polyethylene glycol)-g-dopamine(PCPD)and amino-terminated Pluronic F127(APF)mi-celles loaded with astragaloside IV(AS)was developed for this pur-pose,as shown in Fig.1A[6]. 展开更多

Skeletal stem/progenitor cell(SSPC)senescence is a major cause of decreased bone regenerative potential with aging,but the causes of SSPC senescence remain unclear.In this study,we revealed that macrophages in calluses secrete prosenescent factors,including grancalcin(GCA),during aging,which triggers SSPC senescence and impairs fracture healing.Local injection of human rGCA in young mice induced SSPC senescence and delayed fracture repair.Genetic deletion of Gca in monocytes/macrophages was sufficient to rejuvenate fracture repair in aged mice and alleviate SSPC senescence.Mechanistically,GCA binds to the plexin-B2 receptor and activates Arg2-mediated mitochondrial dysfunction,resulting in cellular senescence.Depletion of Plxnb2 in SSPCs impaired fracture healing.Administration of GCA-neutralizing antibody enhanced fracture healing in aged mice.Thus,our study revealed that senescent macrophages within calluses secrete GCA to trigger SSPC secondary senescence,and GCA neutralization represents a promising therapy for nonunion or delayed union in elderly individuals. 展开更多

The thermoregulating function of skin that is capable of maintaining body temperature within a thermostatic state is critical.However,patients suffering from skin damage are struggling with the surrounding scene and situational awareness.Here,we report an interactive self-regulation electronic system by mimicking the human thermos-reception system.The skin-inspired self-adaptive system is composed of two highly sensitive thermistors(thermal-response composite materials),and a low-power temperature control unit(Laserinduced graphene array).The biomimetic skin can realize self-adjusting in the range of 35–42℃,which is around physiological temperature.This thermoregulation system also contributed to skin barrier formation and wound healing.Across wound models,the treatment group healed~10%more rapidly compared with the control group,and showed reduced inflammation,thus enhancing skin tissue regeneration.The skin-inspired self-adaptive system holds substantial promise for nextgeneration robotic and medical devices. 展开更多

AIM:To evaluate if topical use of αB-crystallin minipeptides supports corneal healing following flap surgery.METHODS:Cultured corneal cells were treated with fluorescent taggedαB-crystallin mini-peptides to assess its internalization.Cultured corneal cells pre-treated with or without the mini-peptides were exposed to H_(2)O_(2) and cell viability was examined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)assay.Elongation of neurites of cultured trigeminal neurones was examined following treatment either withαB-crystallin mini-peptides or protein.Cultured trigeminal neurones were pre-treated either with αB-crystallin mini-peptides or crystallin protein and exposed to H_(2)O_(2) and presence of beading in the dendrites and axons was assessed.Corneal flap surgery was conducted on rabbit cornea and treated topically either withαB-crystallin peptide(0.5 mg/mL thrice daily for 14d)or phosphate-buffered saline(PBS).Corneal healing was evaluated under slit-lamp biomicroscope,mRNA expression of inflammatory cytokines were assessed and the corneas were evaluated by histopathology.RESULTS:Internalization ofαB-crystallin mini-peptides was ascertained by the detection of fluorescence within the corneal cells.The MTT assay revealed that treatment withαB-crystallin mini-peptide reduced cell death induced by H_(2)O_(2) treatment.The mini-peptides did not influence the elongation of trigeminal neurites,but significantly(P<0.05)reduced beading in the neurites.In rabbit eye,the treated corneas showed reduced hyper-reflective zones(P<0.05)and suppression in the expression of inflammatory cytokines.Histopathological examination also revealed reduction of inflammatory response in treated corneas.CONCLUSION:TheαB-crystallin mini-peptides restrict the damage to corneal cells and neurons and aids in corneal healing. 展开更多

Delayed and nonhealing of diabetic wounds imposes substantial economic burdens and physical pain on patients.Mesenchymal stem cells(MSCs)promote diabetic wound healing.Particularly when MSCs aggregate into multicellular spheroids,their therapeutic effect is enhanced.However,traditional culture platforms are inadequate for the efficient preparation and delivery of MSC spheroids,resulting in inefficiencies and inconveniences in MSC spheroid therapy.In this study,a three-dimensional porous nanofibrous dressing(NFD)is prepared using a combination of electrospinning and homogeneous freeze-drying.Using thermal crosslinking,the NFD not only achieves satisfactory elasticity but also maintains notable cytocompatibility.Through the design of its structure and chemical composition,the NFD allows MSCs to spontaneously form MSC spheroids with controllable sizes,serving as MSC spheroid delivery systems for diabetic wound sites.Most importantly,MSC spheroids cultured on the NFD exhibit improved secretion of vascular endothelial growth factor,basic fibroblast growth factor,and hepatocyte growth factor,thereby accelerating diabetic wound healing.The NFD provides a competitive strategy for MSC spheroid formation and delivery to promote diabetic wound healing. 展开更多

Diabetic wounds, as a complication of diabetes, are slow to heal and seriously affect the quality of life of patients. Functional hydrogel dressing is an effective approach to improve diabetic wound healing. Electrical stimulation (ES) therapy is conducive to promoting cell migration and wound healing. In this work, a multifunctional PPTZ hydrogel wound dressing was developed by freeze-thaw method with polyvinyl alcohol (PVA), phytic acid (PA), tannic acid (TA), and Zinc chloride. The obtained PPTZ hydrogel has good mechanical properties (stress and strain of 700.03 kPa and 575.08%), light transmittance (close to 100%) and antibacterial rate (over 75%). With good biocompatibility, antioxidant abilities and conductivity, the PPTZ hydrogel could effectively promote the healing of diabetic wounds with two weeks under the action of electric field, which provides an auxiliary treatment strategy for diabetic patients. 展开更多

Diabetic foot ulcers are a prevalent complication that can significantly impact quality of life and necessitate high-level amputations. Hence, early diagnosis and treatment, elucidation of pathogenesis, and targeted countermeasures assume paramount importance. Wound healing entails a complex process wherein various components such as inflammatory cells, extracellular matrix, and immune cells intricately interact with each other. Due to the vulnerability of the skin to damage, inadequate or impaired wound healing has emerged as an urgent clinical challenge requiring resolution. This paper provides a comprehensive overview of the pathogenesis, diagnosis, and treatment of diabetic foot ulcers in order to offer theoretical guidance for specific interventions. 展开更多

The main goal of the article is the creation and study of thermosensitive and wound-healing gelatin-alginate bio-polymer hydrogels modified with humic acids.Their rheological properties,swelling and contraction behavior were experimentally investigated,elucidated using Fourier transform infrared spectroscopy and used to achieve the physiological melting point,which is necessary for successful drug delivery.It has been shown that in the gelatin-alginate-humic acid biopolymer hydrogels systems,it is possible to obtain a gel-sol transition temperature close to the physiological temperature of 37°C,which is important for drug delivery in the treatment of wounds.By changing the type and concentration of humic acids in the gelatin-alginate hydrogel,it turned out to be achiev-able to regulate the softening time of the gel on the human body in the range from 6 to 20 min,which provides the possibility of controlled prolonged delivery of drugs.Based on the study of the influence of calcium ions on the properties of humic acids and ion exchange,as well as the interaction of humic acids,sodium alginate and gelatin with the formation of tighter gel networks,approaches to regulate the rate of softening of hydrogels at physiological temperature and their swelling,which simulates the absorption of exudate,were proposed and implemented.In addition,low shrinkage of the hydrogel surface due to cross-linking of gelatin-alginate networks when modified with humic acids was experimentally confirmed,which is important for avoiding problems of wound contracture and contour deformations when using dressings for wound healing.Thus,the developed opti-mized innovative biopolymer hydrogels synergistically combine the outstanding properties of natural molecular polymers and humic acids and are promising for the creation of effective medicines for wound healing. 展开更多

In this editorial,we discuss the article by Wen et al published.Diabetic foot ulcers are prevalent and serious complications of diabetes,significantly impacting patients’quality of life and often leading to disability or death,thereby placing a heavy burden on society.Effective diabetic wound healing is hindered by an imbalance in macrophage polarization;many macrophages fail to transition from the pro-inflammatory M1 phenotype to the anti-inflammatory M2 phenotype,which is crucial for tissue remodelling and repair.The wound healing process is both dynamic and complex.Healthy M1 macrophages,which have strong phagocytic abilities,are vital during the inflammatory phase of diabetic wound healing.However,the failure to transition to M2 macrophages during the proliferative phase hinders wound healing.We anticipate the development of new therapies that can repair damaged M1 macrophages during the inflammatory phase and promote M2 macrophage polarization during the proliferative phase,thereby enhancing the overall healing process. 展开更多

This comprehensive review explores the intricate dynamics between psychosocial factors and chronic wound healing processes, specifically focusing on prevalent conditions such as pressure ulcers, diabetic foot ulcers, and venous leg ulcers. By examining the roles of psychiatric conditions, including depression, anxiety, and post-traumatic stress disorder (PTSD), this paper illuminates how these factors intricately influence wound healing dynamics, including mechanisms of pain perception and inflammatory responses. Furthermore, we evaluate the effectiveness of integrated biopsychosocial interventions, which encompass a holistic approach to wound care, thereby enhancing healing outcomes for dermatology patients. Future studies should focus on investigating the specific psychosocial determinants that significantly influence wound healing, exploring novel therapeutic strategies, and implementing personalized interventions to meet the unique needs of each patient. Such endeavors hold promise in advancing the fields of psychodermatology and wound management, fostering a deeper understanding and application of psychosocial considerations in dermatological care. 展开更多

Recently transmural healing (TH) has become a subject of increasing interest as a potential therapeutic purpose for inflammatory bowel disease (IBD). Crohn’s disease (CD) is characterized by chronic inflammation of the gastrointestinal tract, which can involve any part of the digestive tract, and the lesions are usually discontinuous, with progressive and destructive transmural lesions that can lead to irreversible damage such as fibrotic strictures, complications such as fistulas and abscesses. Disease remission remains the primary goal of therapeutic management;however transmural healing is a very promising endpoint for monitoring treatment response. Along with small bowel imaging tests such as computed tomography scans Intestinal imaging (CTE), magnetic resonance intestinal imaging (MRE), intestinal ultrasound (IUS) and other related imaging technologies are popularized in CD diagnosis and treatment benefit. Transmural healing has been initially used in clinical practice and the correlation between its rules and long-term clinical remission has been explored. 展开更多

Diabetes mellitus(DM),an increasingly prevalent chronic metabolic disease,is characterised by prolonged hyperglycaemia,which leads to long-term health consequences.Although much effort has been put into understanding the pathogenesis of diabetic wounds,the underlying mechanisms remain unclear.The advent of single-cell RNA sequencing(scRNAseq)has revolutionised biological research by enabling the identification of novel cell types,the discovery of cellular markers,the analysis of gene expression patterns and the prediction of develop-mental trajectories.This powerful tool allows for an in-depth exploration of pathogenesis at the cellular and molecular levels.In this editorial,we focus on progenitor-based repair strategies for diabetic wound healing as revealed by scRNAseq and highlight the biological behaviour of various healing-related cells and the alteration of signalling pathways in the process of diabetic wound healing.ScRNAseq could not only deepen our understanding of the complex biology of diabetic wounds but also identify and validate new targets for inter-vention,offering hope for improved patient outcomes in the management of this challenging complication of DM. 展开更多

As the body’s integumentary system,the skin is vulnerable to injuries.The subsequent wound healing processes aim to restore dermal and epidermal integrity and functionality.To this end,multiple tissue-resident cells and recruited immune cells cooperate to efficiently repair the injured tissue.Such temporally-and spatially-coordinated interplay necessitates tight regulation to prevent collateral damage such as overshooting immune responses and excessive inflammation.In this context,regulatory T cells(Tregs)hold a key role in balancing immune homeostasis and mediating cutaneous wound healing.A comprehensive understanding of Tregs’multifaceted field of activity may help decipher wound pathologies and,ultimately,establish new treatment modalities.Herein,we review the role of Tregs in orchestrating the regeneration of skin adnexa and catalyzing healthy wound repair.Further,we discuss how Tregs operate during fibrosis,keloidosis,and scarring. 展开更多

In this editorial,we comment on an article by Liao et al published in the current issue of the World Journal of Diabetes.We focus on the clinical significance of tibial transverse transport(TTT)as an effective treatment for patients with diabetic foot ulcers(DFU).TTT has been associated with tissue regeneration,improved blood circulation,reduced amputation rates,and increased expression of early angiogenic factors.Mechanistically,TTT can influence macrophage polarization and growth factor upregulation.Despite this potential,the limitations and conflicting results of existing studies justify the need for further research into its optimal application and development.These clinical implications highlight the efficacy of TTT in recalcitrant DFU and provide lasting stimuli for tissue re-generation,and blood vessel and bone marrow improvement.Immunomodu-lation via systemic responses contributes to its therapeutic potential.Future studies should investigate the underlying molecular mechanisms to enhance our understanding and the efficacy of TTT.This manuscript emphasizes the potential of TTT in limb preservation and diabetic wound healing and suggests avenues for preventive measures against limb amputation in diabetes and peripheral artery disease.Here,we highlight the clinical significance of the TTT and its importance in healing DFU to promote the use of this technique in tissue regeneration. 展开更多

Wound repair is a complex challenge for both clinical practitioners and researchers.Conventional approaches for wound repair have several limitations.Stem cell-based therapy has emerged as a novel strategy to address this issue,exhibiting significant potential for enhancing wound healing rates,improving wound quality,and promoting skin regeneration.However,the use of stem cells in skin regeneration presents several challenges.Recently,stem cells and biomaterials have been identified as crucial components of the wound-healing process.Combination therapy involving the development of biocompatible scaffolds,accompanying cells,multiple biological factors,and structures resembling the natural extracellular matrix(ECM)has gained considerable attention.Biological scaffolds encompass a range of biomaterials that serve as platforms for seeding stem cells,providing them with an environment conducive to growth,similar to that of the ECM.These scaffolds facilitate the delivery and application of stem cells for tissue regeneration and wound healing.This article provides a comprehensive review of the current developments and applications of biological scaffolds for stem cells in wound healing,emphasizing their capacity to facilitate stem cell adhesion,proliferation,differentiation,and paracrine functions.Additionally,we identify the pivotal characteristics of the scaffolds that contribute to enhanced cellular activity. 展开更多
