Disclosed is a multi-functional nanoparticle delivery system comprising a biodegradable core of poly(lactic-co-glycolic acid) (PLGA) or calcium phosphate (CaP), encapsulating a nicotinamide adenine dinucleotide (NAD+) precursor and a sirtuin activator. Surrounding the core is a liposomal or polymeric layer containing one or more senolytic agents, and an outer layer of magnetic iron oxide nanoparticles for targeted delivery, external manipulation, and imaging. In some embodiments, the nanoparticle surface is functionalized for conjugation with autologous mesenchymal stem cells to enhance homing and regenerative potential. The system is pH-responsive, releasing its payload in acidic microenvironments typical of senescent or diseased cells, while remaining stable at physiological pH. This integrated design supports NAD+ restoration, sirtuin activation, senescent cell clearance, and tissue regeneration. Applications include treatment of age-related diseases, regenerative medicine, cardiovascular and neurodegenerative disorders, and cosmetic skin rejuvenation.

The present application creatively designs an anti-aging composition for improving cardiovascular aging, which improves cardiovascular aging from four dimensions of "myocardial energy supply + anti-hypertrophy + endothelial protection + anti-oxidation". Coenzyme Q10 can restore myocardial mitochondrial ATP production, honokiol can reverse myocardial hypertrophy through NAD+ deacetylase, quercetin can improve endothelial function and reduce blood pressure, and L-ergothioneine can protect vascular endothelial cells from oxidative damage and inhibit the formation of ox-LDL. Through research, it is found that the four can cooperate and synergize with each other, and can jointly play an excellent role in improving cardiovascular aging, and achieve multiple protection for cardiovascular aging.

The invention discloses an application of SIRT1 activator dihydromyricetin in preparation of a medicine for treating acute liver injury. It is proved for the first time that dihydromyricetin serves as an effective liver protective agent, and acute liver injury is relieved through an unknown acetylation-dependent mechanism. DMY mitigates ALI by mitigating oxidative stress and inhibiting inflammatory response. In mechanism, DMY recovers expression of deacetylase SIRT1 in liver macrophages, SIRT1 and PRDX1 directly interact with each other, and deacetylation is carried out on the PRDX1 at a lysine 35 site. This deacetylation event reactivates the antioxidant function of PRDX1, inhibits the generation of proinflammatory cytokines, and inhibits polarization of M1 type macrophages, thereby remodeling the inflammatory microenvironment during ALI. The protection effect of DMY is reproduced through gene recovery SIRT1, and an SIRT1-PRDX1 shaft is determined as a core mediating factor of the SIRT1-PRDX1 shaft.
