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.

The application discloses a kind of based on underwater structure settlement nondestructive intelligent monitoring optical fiber layout method, comprising the following steps: optical fiber layout is carried out on dry canal bottom surface and slope surface;Adopt negative pressure suction disc assembly and fix optical fiber on canal bottom concrete slab;When disassembling, pressurized grouting is added through communicating pipe, and biological-based adhesive strip is expanded, the negative pressure adsorption state is destroyed, and the negative pressure suction disc assembly is removed.The application can obtain canal bottom settlement data in real time before, during and in the operation period of crossing engineering construction by laying optical fiber on dry canal bottom surface and slope surface and fixing optical fiber on concrete slab by negative pressure suction disc assembly, provides direct basis for judging the influence of crossing engineering on dry canal deformation, and does not need to punch or anchor in concrete bottom plate, completely avoids damage to canal bottom structure, and will not cause any pollution to dry canal water, meets the high protection level requirement of South-to-North Water Diversion Project.

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.
