Herein, we propose hemostatic microsheets based on quaternized chitosan-g-gallic acid (QCS-GA) and oxidized hyaluronic acid (OHA), which merge the benefits of sponges, hydrogels, and powders for rapid hemostasis and efficient wound healing. Specifically, they exhibit a large specific surface area and excellent hydrophilicity, rapidly absorbing blood and self-gelling through electrostatic interaction and Schiff base crosslinking. And this results in dense, porous hydrogel adhesives with superior mechanical properties, adhesion strength, and ultra-high burst pressure. Furthermore, the microsheets are biocompatible, biodegradable, and possess procoagulant, antibacterial, and antioxidant properties. In mouse and rat liver hemorrhage models, the optimized formulation (QCS-GA + OHA4) demonstrated superior hemostatic effects compared to Celox. In particular, QCS-GA + OHA4 microsheets could stop bleeding quickly from rat femoral artery transection and deliver lidocaine to provide analgesia during emergency treatment. Additionally, they promoted wound healing in mouse full-thickness skin defect wound. These easy-to-manufacture hemostatic microsheets are adaptable to irregular wounds, providing a novel solution for rapid hemostasis and wound healing.</div></div>","PeriodicalId":254,"journal":{"name":"Biomaterials","volume":"315 ","pages":"Article 122936"},"PeriodicalIF":12.8,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142602175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the in vitro study, we first found that the BNPD-Ce6-mediated sonodynamic action (SDA) induced remarkable viability loss, DNA damage, and cell death in the GBM cells (GBCs) but not macrophages. Surprisingly, the SDA-exposed GBCs displayed a ferroptotic phenotype while the SDA-exposed macrophages underwent immuno-stimulatory autophagy and potently potentiated the SDA's toxicity to the GBCs. The ferroptotic GBCs induced by the SDA were found to be quasi-immunogenic, characterized by the emission of some alarmins such as ATP, HSP90, and CRT, but absent HMGB1, a potent endogenous adjuvant. As such, the SDA-stressed GBCs were unable to stimulate the BMDMs. This defect, interestingly, could be rescued by platelets as a donor of HMGB1 which markedly enhanced the BNPD-Ce6's sonotoxicity to the GBCs. In the in vivo study, we first employed BNPD-Ce6-loaded platelets to achieve ultrasound-triggered, targeted delivery of BNPD-Ce6 in grafted intra-cranial GBMs and subsequent sonodynamic tumor damage. An SDT regimen designed based on these results slowed the growth of grafted intra-cranial GBMs and significantly increased the survival of the host animals. Pathological examination of the SDT-treated GBMs revealed tissue necrosis and destruction and validated the in vitro observations. Finally, the depletion of macrophages was found to abrogate the efficacy of the SDT in subcutaneous GBC grafts.
