Immunotherapy offers significant potential but is often hampered by the immunosuppressive environment in oral squamous cell carcinoma(OSCC).To address this,we propose an enhanced immunotherapeutic strategy that revitalizes the tumor immune microenvironment(TIME)in OSCC by integrating upconversion-based photodynamic therapy(PDT)with *** a red blood cell membraneinspired biomimetic nanoplatform,our approach concurrently delivers chlorin e6@upconversion nanoparticles(Ce6@UCNP)and doxorubicin(DOX).By leveraging fluorescence resonance energy transfer(FRET)for 980 nm to 660 nm upconversion excitation,we address challenges such as limited tissue penetration and tissue damage,as well as nanoplatform issues including immunogenicity and targeting inaccuracy Our integrated approach enhances PDT and chemotherapy with the goal of transforming immunologically“cold”tumors into“hot”ones through a cascaded therapy,thereby revitalizing the tumor immune microenvironment in OSCC.

We investigate the electronic structures and superconductivities of new superconductor MgB2 with different lattice parameters by means of multiple-scattered-Xα calculation. It is shown that the lattice parameters have great effect on the superconductivity of MgB2. The results of this paper show that the density of states at the Fermi level decreases with the decreasing lattice parameters. The effects are very more sensitive substantially to the change of the lattice parameter a as compared with that of the lattice parameter c. Correspondingly, the superconducting transition temperature TC decreases correspondingly mainly with decreasing the lattice parameter a. Our results are in good agreement with the experiments.
