The utility model has the advantage that the processed material is directly packed, solves the existing roasting furnace discharge and the transportation process, the material is easy to be damp and contact with external material, leads to the metamorphic problem of problem.

This invention relates to the field of biomedical technology, providing a method for preparing a drug-eluting microsphere suspension, the drug-eluting microsphere suspension, and its applications. The method includes: S1. Removing the storage solution from the drug-eluting microspheres to obtain a microsphere precipitate; S2. Adding a chemotherapy drug solution to the microsphere precipitate to load the drug into the microspheres; S3. Mixing physiological saline and a non-ionic contrast agent at a volume ratio of 1.5:1 to prepare a dilution medium; S4. Adding the dilution medium prepared in step S3 to the microspheres after drug loading in step S2, so that the total suspension volume reaches a preset multiple of the microsphere precipitate volume, obtaining a microsphere suspension; S5. Shaking the microsphere suspension obtained in step S4 to mix thoroughly. This invention significantly reduces postoperative chemical stimulation pain by increasing the dilution factor of the drug-eluting microsphere suspension, while unexpectedly improving tumor response, achieving a synergistic effect of pain reduction and efficacy enhancement.

This invention discloses an siRNA that inhibits IL-25 gene expression and its application. The siRNA sequence provided by this invention can specifically knock down IL-25 expression levels. Furthermore, by modifying the sense strand with thiocyanate, this invention enhances the ability of siRNA to resist enzymatic hydrolysis in serum and prolongs its duration of action without significantly increasing cytotoxicity, thus bringing important application value to the treatment of autoimmune diseases.
