Abstract:
In case of ischemic stroke(IS),thrombus in the vascular system can cause ischemia and hypoxia in brain tissue,produce inflammatory cytokines and cause brain tissue damage,while reactive oxygen species during ischemia-reperfusion cause stress injury.Conventional drug administra-tion is limited by the selective permeability of the blood-brain barrier and the low bioavailability of the drug itself,and its therapeutic effect against IS is unsatisfactory.Nanomedicine is expected to bring hope in that it has a unique mechanism of action and can cross the blood-brain barrier to reach the periphery of the infarct,release drugs or therapeutic genes,and exert a therapeutic effect.Nanomedi-cine inhibits platelet aggregation,enhances the efficacy of thrombolytic drugs,dissolves thrombus,increases blood supply to ischemic areas,eliminates reactive oxygen species and weakens injury response by fighting inflammatory cytokines.Loaded therapeutic genes regulate the differentiation pro-cess of neural stem cells,increase the number of neurons,induce the occurrence of blood vessels,and enhance the repair function of brain tissue.Nanomedicines can not only improve pharmacokinetics and pharmacodynamics to achieve more effective drug treatment,but also use nanoimaging technology to achieve real-time monitoring and condition assessment of therapy.
