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

Diabetes has long been considered a risk factor in implant therapy and impaired wound healing in soft and hard oral tissues.Magnesium has been proved to promote bone healing under normal conditions.Here,we elucidate the mechanism by which Mg^(2+)promotes angiogenesis and osseointegration in diabetic status.We generated a diabetic mice model and demonstrated thealveolar bone healing was compromised,with significantly decreased angiogenesis.We then developed Mg-coating implants with hydrothermal synthesis.These implants successfully improved the vascularization and osseointegration in diabetic status.Mechanically,Mg^(2+)promoted the degradation of Kelch-like ECH-associated protein 1 (Keap1) and the nucleation of nuclear factor erythroid 2-related factor 2 (Nrf2) by up-regulating the expression of sestrin 2 (SESN2) in endothelial cells,thus reducing theelevated levels of oxidative stress in mitochondria and relieving endothelial cell dysfunction under hyperglycemia.Altogether,our data suggested that Mg^(2+)promoted angiogenesis and osseointegration in diabetic mice by regulating endothelial mitochondria metabolism. 展开更多

Reconstruction of irregular oral-maxillofacial bone defects with an inflammatory microenvironment remains a challenge,as chronic local inflammation can largely impair bone healing.Here,we used magnesium silicate nanospheres(MSNs)to load microRNA-146a-5p(miR-146a)to fabricate a nanobiomaterial,MSN+miR-146a,which showed synergistic promoting effects on the osteogenic differentiation of human dental pulp stem cells(hDPSCs).In addition,miR-146a exhibited an anti-inflammatory effect on mouse bone marrow-derived macrophages(BMMs)under lipopolysaccharide(LPS)stimulation by inhibiting the NF-κB pathway via targeting tumor necrosis factor receptor-associated factor 6(TRAF6),and MSNs could simultaneously promote M2 polarization of BMMs.MiR-146a was also found to inhibit osteoclast formation.Finally,the dual osteogenic-promoting and immunoregulatory effects of MSN+miR-146a were further validated in a stimulated infected mouse mandibular bone defect model via delivery by a photocuring hydrogel.Collectively,the MSN+miR-146a complex revealed good potential in treating inflammatory irregular oralmaxillofacial bone defects. 展开更多

Reactive oxygen species(ROS)plays important roles in living organisms.While ROS is a double-edged sword,which can eliminate drug-resistant bacteria,but excessive levels can cause oxidative damage to cells.A core–shell nanozyme,Ce O_(2)@ZIF-8/Au,has been crafted,spontaneously activating both ROS generating and scavenging functions,achieving the multifaceted functions of eliminating bacteria,reducing inflammation,and promoting wound healing.The Au Nanoparticles(NPs)on the shell exhibit high-efficiency peroxidase-like activity,producing ROS to kill bacteria.Meanwhile,the encapsulation of Ce O_(2) core within ZIF-8 provides a seal for temporarily limiting the superoxide dismutase and catalase-like activities of Ce O_(2) nanoparticles.Subsequently,as the ZIF-8 structure decomposes in the acidic microenvironment,the Ce O_(2) core is gradually released,exerting its ROS scavenging activity to eliminate excess ROS produced by the Au NPs.These two functions automatically and continuously regulate the balance of ROS levels,ultimately achieving the function of killing bacteria,reducing inflammation,and promoting wound healing.Such innovative ROS spontaneous regulators hold immense potential for revolutionizing the field of antibacterial agents and therapies. 展开更多

Background: Bilayer artificial dermis promotes wound healing and offers a treatment option for chronic wounds. Aim: Examine the clinical efficacy of bilayer artificial dermis combined with Vacuum Sealing Drainage (VSD) technology in the treatment of chronic wounds. Method: From June 2021 to December 2023, our hospital treated 24 patients with chronic skin tissue wounds on their limbs using a novel tissue engineering product, the bilayer artificial dermis, in combination with VSD technology to repair the wounds. The bilayer artificial dermis protects subcutaneous tissue, blood vessels, nerves, muscles, and tendons, and also promotes the growth of granulation tissue and blood vessels to aid in wound healing when used in conjunction with VSD technology for wound dressing changes in chronic wounds. Results: In this study, 24 cases of chronic wounds with exposed bone or tendon larger than 1.0 cm2 were treated with a bilayer artificial skin combined with VSD dressing after wound debridement. The wounds were not suitable for immediate skin grafting. At 2 - 3 weeks post-treatment, good granulation tissue growth was observed. Subsequent procedures included thick skin grafting or wound dressing changes until complete wound healing. Patients were followed up on average for 3 months (range: 1 - 12 months) post-surgery. Comparative analysis of the appearance, function, skin color, elasticity, and sensation of the healed chronic wounds revealed superior outcomes compared to traditional skin fl repairs, resulting in significantly higher satisfaction levels among patients and their families. Conclusion: The application of bilayer artificial dermis combined with VSD technology for the repair of chronic wounds proves to be a viable method, yielding satisfactory therapeutic effects compared to traditional skin flap procedures. 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

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

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

Photobiomodulation therapy(PBMT)is a rapidly growing approach to the healing,stimulation,protection,and regeneration of many human organs and tissue types.PBMT started in the 1960s as low-level laser therapy for wound healing,but since then the introduction of light-emitting diodes(LEDs)has dramatically increased the number of applications and reports of positive results.PBMT generally uses red(620-700 nm)and/or near-infrared(780-1270 nm)wavelengths of light at an intensity that causes no tissue heating,and its activity is based on well-established biological and cellular mechanisms(de Freitas and Hamblin,2016).While laser therapists continue to use various types of laser in their office practice,LEDs are ideally suited for home use devices because they are completely safe and without any known significant adverse effects.Among the various body parts on which PBMT has been shown to exert beneficial effects,the brain stands out as perhaps the most promising overall.PBMT has been shown to reduce neuroinflammation,while increasing mitochondrial function,oxygen consumption,and blood flow within the brain(Hamblin,2016).Moreover,PBMT can stimulate the processes of synaptogenesis,neurogenesis,and neuroplasticity thus helping the brain to heal itself. 展开更多

Precise orchestration of cell fate determination underlies the success of scaffold-based skeletal regeneration.Despite extensive studies on mineralized parenchymal tissue rebuilding,regenerating and maintaining undifferentiated mesenchyme within calvarial bone remain very challenging with limited advances yet.Current knowledge has evidenced the indispensability of rebuilding suture mesenchymal stem cell niches to avoid severe brain or even systematic damage.But to date,the absence of promising therapeutic biomaterials/scaffolds remains.The reason lies in the shortage of fundamental knowledge and methodological evidence to understand the cellular fate regulations of scaffolds.To address these issues,in this study,we systematically investigated the cellular fate determinations and transcriptomic mechanisms by distinct types of commonly used calvarial scaffolds.Our data elucidated the natural processes without scaffold transplantation and demonstrated how different scaffolds altered in vivo cellular responses.A feasible scaffold,polylactic acid electrospinning membrane(PLA),was next identified to precisely control mesenchymal ingrowth and self-renewal to rebuild non-osteogenic suture-like tissue at the defect center,meanwhile supporting proper osteointegration with defect bony edges.Especially,transcriptome analysis and cellular mechanisms underlying the well-orchestrated cell fate determination of PLA were deciphered.This study for the first time cellularly decoded the fate regulations of scaffolds in suture-bony composite defect healing,offering clinicians potential choices for regenerating such complicated injuries. 展开更多

Objective:To assess the antimicrobial,antibiofilm,anti-inflammatory,angiogenic,and wound healing activities of zinc nanoparticles(ZNPs)green synthesized using Ferula macrecolea extract.Methods:The green synthesis was conducted using the precipitation method.Then,the minimum inhibitory concentration(MIC),minimum bactericidal concentration(MBC),and minimum biofilm inhibition concentration 50%(MBIC50)of ZNPs against Staphylococcus aureus(S.aureus)and Pseudomonas aeruginosa(P.aeruginosa)were evaluated.The effects of ZNPs on the gene expressions of Staphylococcus spp.[intracellular adhesion A(icaA)and D(icaD)]and P.aeruginosa(rhlI and rhlR)were investigated using quantitative real-time PCR.In addition,the effects of ZNPs on wound healing,angiogenesis,and anti-inflammatory markers were assessed.Results:The green-synthesized ZNPs demonstrated significant antimicrobial efficacy against S.aureus and P.aeruginosa.The biofilm formation in S.aureus and P.aeruginosa was also inhibited by ZNPs with MBIC50 values of 3.30μg/mL and 2.08μg/mL,respectively.Additionally,ZNPs downregulated the expression of biofilm-related genes icaA,icaD,rhlI,and rhlR in the tested bacteria.They also demonstrated promising in vitro wound healing effects by promoting fibroblast cell proliferation and wound closure in a dose-dependent manner.A significant increase in the expression of HLA-G5 and VEGF-A genes as well as a marked decrease in the expression of NF-κB,IL-1β,and TNF-αgenes were observed in cells treated with ZNPs compared to the control group(P<0.05).Conclusions:ZNPs display promising antibacterial effects against S.aureus and P.aeruginosa and wound-healing effects by inhibiting biofilm formation,inducing angiogenesis,and reducing inflammation.However,further studies must be conducted to specify the accurate mechanisms of action and toxicity of ZNPs. 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

Although tuberculosis has become more common in recent years, it still accounts for just a small percentage of cases of chronic otitis media. Common symptoms of tuberculous otitis media(TOM) include otorrhoea, hearing loss, and multiple tympanic membrane perforations. Due to its rarity, the illness is frequently misdiagnosed. When a patient does not improve with standard antibacterial and antifungal treatment, this may be a possible diagnosis to explore.

AIM:To evaluate if topical use ofαB-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 H2O2 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 withαB-crystallin mini-peptides or crystallin protein and exposed to H2O2 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 H2O2 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
