This invention discloses a thermosensitive hydrogel loaded with anti-inflammatory small molecules, its preparation method, and its applications, relating to the field of biomedical technology. It comprises mesenchymal stem cell-derived exosomes loaded with anti-inflammatory small molecules, sodium hyaluronate, a thermosensitive hydrogel matrix, and an enzymatic debridement agent. This invention encapsulates papain with enzymatic debridement function, anti-inflammatory small molecules, and mesenchymal stem cell-derived exosomes as the main body of repair activity within a thermosensitive hydrogel matrix composed of a fixed ratio of poloxamer 407 and poloxamer 188. This composition is liquid at low temperatures, making it easy to apply, and transforms in situ into a semi-solid gel upon contact with oral temperature, achieving wound adhesion and long-term residence. Papain is used for initial debridement, creating conditions for subsequent repair; the bioaffinity between the anti-inflammatory small molecules and exosomes enables controlled and sustained release of the active ingredients; and finally, mesenchymal stem cell-derived exosomes promote wound repair.

This invention relates to a seamless laser carrier film, a seamless laser film, its preparation method, and its application. The preparation method of the seamless laser film includes: S1. Composite a PE film and a PET film to obtain a composite base film; S2. Imprinting a laser pattern onto the PE film using a double-plate seamless molding machine, followed by vacuum deposition to form a dielectric layer, thus obtaining a seamless laser carrier film; S3. Coating the dielectric layer with an aqueous resin to form an aqueous protective layer, thus obtaining a seamless laser film. This invention, through the synergistic combination of the composite base film structure and special process steps, completely solves the industry pain point that conventional aluminum transfer technology still struggles to eliminate seams even with the application of infinitely cyclic nickel plates. The stress buffering capacity of the PE layer ensures the physical continuity of the molding structure, while the subsequent continuous deposition of the dielectric layer achieves seamless reconstruction of the optical surface. Together, these two processes eliminate periodic seam lines caused by substrate deformation, uneven release, or mechanical tolerances.
