Recent advances in the combined delivery platform that integrate nano-/microscale carriers and with 3D hydrogel network for bone regeneration are *** strategies for bioactive molecules delivery involving nanoparticles, nanosheets, and microspheres, along with extra stimuli such as near-infrared light, temperature changes, ultrasonication, and inflammatory conditions, are *** prospects and challenges for the clinical translation and the development of nano-/microscale incorporated hydrogel-based delivery platform are discussed. Bioactive molecules have shown great promise for effectively regulating various bone formation processes, rendering them attractive therapeutics for bone regeneration. However, the widespread application of bioactive molecules is limited by their low accumulation and short half-lives in vivo. Hydrogels have emerged as ideal carriers to address these challenges, offering the potential to prolong retention times at lesion sites, extend half-lives in vivo and mitigate side effects, avoid burst release, and promote adsorption under physiological conditions. This review systematically summarizes the recent advances in the development of bioactive molecule-loaded hydrogels for bone regeneration, encompassing applications in cranial defect repair, femoral defect repair, periodontal bone regeneration, and bone regeneration with underlying diseases. Additionally, this review discusses the current strategies aimed at improving the release profiles of bioactive molecules through stimuli-responsive delivery, carrier-assisted delivery, and sequential delivery. Finally, this review elucidates the existing challenges and future directions of hydrogel encapsulated bioactive molecules in the field of bone regeneration.

The analytic and discretized dissipativity of nonlinear infinite-delay systems of the form x＇（t） = g（x（t）,x（qt））（q∈ （0, 1）, t 〉 0） is investigated. A sufficient condition is presented to ensure that the above nonlinear system is dissipative. It is proved the backward Euler method inherits the dissipativity of the underlying system. Numerical examples are given to confirm the theoretical results.

Ferroptosis represents an oxidative form of iron-dependent cell death resulting from unrestrained peroxidized phospholipids on cellular membranes(Jiang et al.,2021).In recent years,research interest in ferroptosis has increased steeply partly due to its high relevance to diverse diseases(such as cancer and neurodegener-ative diseases)and the enormous potential of ferroptosis induc-ers and inhibitors to treat these diseases(Jiang et al.,2021;Tang et al.,2021.
