The high Ba-Sr rocks can provide significant clues about the evolution of the continent lithosphere,but their petrogenesis remains *** the Late Cretaceous high Ba–Sr granodiorites in the SE Lhasa Block could potentially provide valuable insights into the continent evolution of the Qinghai-Tibet *** U–Pb ages suggest that the granodiorites were emplaced at 87.32±0.43 ***,the high Ba–Sr granodiorites are characterized by elevated K_(2)O+Na_(2)O contents(8.18-8.73 wt%)and K_(2)O/Na_(2)O ratios(0.99-1.25,mostly>1),and belong to high-K calc-alkaline to shoshonitic *** Yonglaga granodiorites show notably high Sr(653-783 ppm)and Ba(1346-1531 ppm)contents,plus high Sr/Y(30.92-38.18)and(La/Yb)_(N)(27.7-34.7)ratios,but low Y(20.0-22.8 ppm)and Yb(1.92-2.19 ppm)contents with absence of negative Eu anomalies(δEu=0.83-0.88),all similar to typical high Ba–Sr *** variable zirconεHf(t)values of-4.58 to+12.97,elevated initial^(87)Sr/^(86)Sr isotopic ratios of 0.707254 to 0.707322 and lowεNd(t)values of-2.8 to-3.6 with decoupling from the Hf system suggest that a metasomatized mantle source included significant recycled ancient *** occurrence of such high Ba–Sr intrusions indicates previous contributions of metasomatized mantle-derived juvenile material to the continents,which imply the growth of continental crust during the Late Cretaceous in the SE *** with regional data,we infer that the underplated mafic magma provides a significant amount of heat,which leads to partial melting of the juvenile *** melting of the metasomatized mantle could produce a juvenile mafic lower crust,from which the high Ba–Sr granitoids were derived from reworking of previous mafic crust during the Late Cretaceous(ca.100-80 Ma)in the SE Lhasa.

The considerable hazard posed by periprosthetic joint infections underlines the urgent need for the rapid advancement of in-situ drug delivery systems within joint materials. However, the pursuit of sustained antibacterial efficacy remains a formidable challenge. In this context, we proposed a novel strategy that leverages swelling and erosion mechanisms to facilitate drug release of drug-loaded ultrahigh molecular weight polyethylene(UHMWPE), thereby ensuring its long-lasting antibacterial *** oxide(PEO), a hydrophilic polymer with fast hydrating ability and high swelling capacity, was incorporated in UHMWPE alongside the antibacterial tea polyphenol(epigallocatechin gallate,EGCG as representative). The swelling of PEO enhanced water infiltration into the matrix, while the erosion of PEO balanced the release of the encapsulated EGCG, resulting in a steady release. The behavior was supported by the EGCG release profiles and the corresponding fitted release kinetic *** demonstrated by segmented antibacterial assessments, the antibacterial efficiency was enhanced 2to 3 times in the PEO/EGCG/UHMWPE composite compared to that of EGCG/UHMWPE. Additionally, the PEO/EGCG/UHMWPE composite exhibited favorable biocompatibility and mechanical performance, making it a potential candidate for the development of drug-releasing joint implants to combat prosthetic bacterial infections.
