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 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.

The invention provides application of diethyl phthalate (DEP) in an induced zebra fish depression model, and belongs to the technical field of animal models. The preparation method comprises the following steps: firstly dissolving a diethyl phthalate solution in DMSO (Dimethylsulfoxide), and then mixing with water to obtain diethyl phthalate feeding water; putting zebra fish into the diethyl phthalate feeding water for feeding; the depression-like phenotype of the zebra fish is confirmed through behavioral testing. The method is simple and convenient to operate, the constructed model can stably reproduce DEP-induced behaviors and molecular level changes, and the method is suitable for plasticizer toxicology screening and depression pathogenesis research; and an economic and efficient research tool capable of replacing mammalian experiments is provided for safety evaluation of DEP and research and development of nervous system drugs.

This invention provides a flame-retardant rubber containing a bismuth-based flame retardant and its preparation method, belonging to the field of flame-retardant rubber technology. This invention uses natural rubber, nitrile rubber, styrene-butadiene rubber, and chloroprene rubber as the main base materials, while introducing at least one of bismuth oxide, bismuth oxychloride, bismuth hydroxide, and bismuth subcarbonate as an environmentally friendly flame retardant, ensuring the product's flame-retardant effect; it also reduces the use of complex solvents and potential by-product emissions, which is an important way to achieve an ideal green lifestyle. Carbon black, stearic acid, zinc oxide, decabromodiphenyl ethane, aluminum diethylphosphinate, diethyl phthalate, paraffin oil, coupling agents, insoluble sulfur, accelerators, antioxidants, and other substances are also added. Through multiple mixing and intensive kneading processes, the product's tensile properties are guaranteed while effectively improving its fire resistance, delaying ignition, reducing flame propagation speed, and enhancing the safety of product use.

This invention relates to an adsorption chromatographic material for technetium in radioactive waste and its preparation method, comprising the following steps: S1, purging air from the pores of a silica matrix; S2, mixing acetophenone, diethyl phthalate, vinylpyridine, and divinylbenzene evenly, then adding initiator azobisisobutyronitrile and initiator V-40 and mixing evenly to obtain a mixture; S3, mixing the mixture with the silica matrix under vacuum conditions, then restoring to atmospheric pressure, and then cycling under vacuum-atmospheric pressure conditions multiple times, finally restoring to atmospheric pressure; S4, subjecting the reaction system after restoring to atmospheric pressure to multiple continuous heatings, finally restoring to room temperature, and rinsing multiple times to obtain the adsorption chromatographic material. Compared with the prior art, this invention directly obtains a pyridine-type weakly basic anion exchange resin through copolymerization, eliminating the chloromethylation and amination processes in the traditional process, greatly simplifying the resin synthesis process, and improving the adsorption chromatographic material for technetium in radioactive waste. 99 Tc has a good adsorption effect.
