Objective:To explore the effectiveness of the"full-chain"integrated medical and elderly care service model in addressing key issues in medical-nursing services such as weak medical support capacity and insufficient provision of community-and home-based medical-nursing services.Methods:The development pathway for the"full-chain"integrated medical-elderly care service standardization system,encompassing core components such as operational mechanisms,smart platforms,policy documents,and quality control systems was systematically outlined.Effectiveness based on dimensions including service coverage,quality improvement,talent development,and social benefits was evaluated.With standardization as the core driver,the'1234567'management model was innovatively implemented.Results:The model leveraged the downward allocation of high-quality resources from tertiary general hospitals to strengthen subdistrict community health service centers.By collaborating with subdistrict elderly-care service centers,it established"subdistrict medical-elderly care and wellness service centers".These centers enhanced the capabilities of"community-embedded elderly-care complexes",including community daytime care centers,established two-way referral channels between medical and elderly care services,aligned with healthcare demands to provide elderly individuals with reliable medical support.It reduced the burden on families and society,stimulated market vitality,boosted domestic demand,promoted the development of integrated medical-elderly care and wellness initiatives,thereby advancing the silver economy.With provincial government endorsement,the model had been applied to 203 communities across 37 counties by the end of 2024.Conclusion:The established"full-chain"integrated medical-elderly care service model facilitates regional high-quality development in integrated care by consolidating healthcare group resources and seamlessly connecting the service chain across hospitals,nursing homes,community institutions,and home-based settings,thereby creating a practical paradigm for comprehensive elderly care service delivery.

As a novel post-translational modification(PTM),lysine 2-hydroxyisobutyrylation(Khib)is considered to regulate gene transcriptional activities in eukaryotic cells;however,the functions of Khib-modified proteins in plants remain unknown.Here,we report that Khib is an evolutionarily-conserved PTM in wheat and its progenitors.A total of 3348 Khib sites on 1074 proteins are iden-tified in common wheat(Triticum aestivum L.)by using affinity purification and mass spectroscopy of 2-hydroxyisobutyrylome.Bioinformatic data indicate that Khib-modified proteins participate in a wide variety of biological and metabolic pathways.Immunoprecipitation confirms that Khib-modified proteins are present endogenously.A comparison of Khib and other main PTMs shows that Khib-modified proteins are simultaneously modified by multiple PTMs.Using mutagenesis experiments and co-immunoprecipitation assays,we demonstrate that Khib on K206 of phospho-glycerate kinase(PGK)is a key regulatory modification for its enzymatic activity,and mutation on K206 affects the interactions of PGK with its substrates.Furthermore,Khib modification of low-molecular-weight proteins is a response to the deacetylase inhibitors nicotinamide and tricho-statin.This study provides evidence to promote our current understanding of Khib in wheat plants,including the cooperation between Khib and its metabolic regulation.
