Wound care is a critical concern due to the rising prevalence of chronic and infected wounds, which demands improved treatment solutions. Conventional dressings often fall short in delivering effective drug release and mechanical performance, limiting their clinical utility. In this study, we present a composite hydrogel dressing incorporating berberine-loaded silk fibroin microspheres and fibers (CGFs). This innovative dressing achieves sustained drug release and enhanced mechanical strength. The hydrogel exhibits excellent antibacterial activity (97.40 ± 0.53%) against , efficient drug loading, and prolonged release profiles. The addition of CGFs significantly enhances mechanical performance (maximum compressive strength of 295.74 ± 27.45 kPa), hemostatic efficiency (0.33%), and adaptability to dynamic wound environments. Our composite hydrogel dressing demonstrates superior biocompatibility and accelerates wound healing by promoting neovascularization, hair follicle regeneration, and collagen deposition. This multifunctional solution offers a promising advancement in next-generation wound care technologies.

Constructing a novel antibacterial platform is of great significance for inhibiting bacterial infections. In this work, we developed a composite hydrogel (CS/PPy/PDA hydrogel) by incorporating photothermal material polypyrrole (PPy), chitosan (CS) and polydopamine (PDA) into poly acrylamide (PAAM) hydrogel network. First, CS/PPy/PDA hydrogel could capture bacteria through strong electrostatic interactions, enhancing the contact between hydrogels and bacteria.

Background: Intervertebral disc (IVD) herniation is a major cause of low back pain and disability, with microdiscectomy being the standard surgical treatment. However, microdiscectomy fails to address annulus fibrosus (AF) defects, increasing the risk of recurrent herniation. Current therapeutic strategies for this condition remain limited in efficacy.

Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a severe complication in patients undergoing long-term bisphosphonate therapy, while our knowledge on the pathogenesis of BRONJ is far from sufficient. Gamma delta (γδ) T cells predominantly distribute in mucosal tissues and play an important role in both immune modulation and bone metabolism; however, the mechanism of γδ T cells in the pathogenesis of BRONJ has not been elucidated. Here, we induced BRONJ-like lesions in wild-type (WT) and T-cell receptor delta-deficient (TCRδ) mice via intraperitoneal zoledronate injection.

Bone metastases occur in 60%-75% of patients with metastatic breast cancer, reducing survival rates and compromising quality of life. Innovative treatments are urgently needed to sequentially eradicate tumor cells and promote bone regeneration. In this study, a novel Janus hydrogel platform (GA@CaMP) is developed for encapsulating the sonosensitive composite nanomaterial MHP, which enables gene expression regulation, along with oxygen-releasing CaO NPs.

Purpose: To develop an in vitro model that mimics aspects of corneal healing in humans for uncovering key mechanisms involved in the mechanisms involved in the healing and scarring processes.
Methods: As part of the healing matrix, TGF-β1-induced and corneal-derived myofibroblasts were cultured in fibrin hydrogels with configurations that recapitulate the healthy (aligned) and wounded (random) microenvironment of the cornea.
Results: Evaluation of cellular alpha smooth muscle actin (α-SMA) and collagen hybridizing peptide (CHP) showed cell and matrix alignment, respectively.
