This invention provides a self-generating ulcer dressing, belonging to the field of medical device technology. The self-generating ulcer dressing comprises a self-generating layer and a conventional ulcer dressing. The conventional ulcer dressing includes a medicated layer and a protective layer, with the self-generating layer either independently between or integrated with both. The self-generating layer is composed of membrane materials such as polylactic acid, polarized cellulose dressing, and polyvinyl alcohol, either alone or in combination with other strongly electronegative biocompatible materials. It generates a Maxwell pulse electric field under external force, accelerating cell regeneration and tissue repair, and promoting ulcer healing. The self-generating layer can be combined with the medicated layer or the protective layer. The protective layer material can be selected from polyacrylic acid resin, diethyl phthalate, or hydroxypropyl methylcellulose, etc. The self-generating ulcer dressing can have a multi-layered or staggered structure, with layers connected by coating, mixing, or compression. The self-generating ulcer patch of the present invention has a flexible design and does not require an external power source. When the self-generating ulcer patch is continuously rubbed and pressed, the self-generating layer is subjected to continuous force to generate a Maxwell pulse electric field and a pulse field current, which can activate cells, promote blood circulation, and work synergistically with ulcer medication to accelerate cell regeneration and tissue repair, thereby achieving the effect of promoting ulcer wound healing.

The invention provides an endophytic acinetobacter (Acinetobacter sp.) Sb2-4 and application of the endophytic acinetobacter (Acinetobacter sp.) Sb2-4, and belongs to the technical field of microorganisms. The endophytic acinetobacter (Acinetobacter sp.) Sb 2-4 is preserved in the China Center for Type Culture Collection on December 1, 2025, the preservation number is CCTCC NO: M20252724, and the 16S rRNA sequence is shown as SEQ ID NO.1. The endophytic acinetobacter can be used for degrading diethyl phthalate, dibutyl phthalate and butyl benzyl phthalate at the same time, and the effect of a biological treatment means of PAEs is improved.

This invention provides a topical composition comprising, by total weight of the composition: 1) 0.5-5% esflurprofen or a pharmaceutically acceptable salt thereof; 2) 1-10% an accelerator; and 3) 0.5-5% peppermint oil; wherein the accelerator is selected from one or more of clomiphene, isopropyl myristate, tributyl acetylacetonate, diethyl phthalate, propylene carbonate, glyceryl triacetate, hexyl laurate, and isopropyl palmitate. The composition provided by this invention exhibits good release and permeation properties, and the topical patch possesses good application properties, good adhesion, and is easy to peel off, maintaining stability during long-term storage.
