Preparation method of multiplex-mode iodized oil nano-emulsion contrast medium
The invention discloses a preparation method of multiplex-mode iodized oil nano-emulsion contrast medium. Aiming at the problems of incomplete detection information of complex diseases and the like because of the shortages when CT (Computed Tomography), MRI (Magnetic Resonance Imaging) and the fluorescence imaging technology are independently used, the invention provides a preparation method of multiplex-mode iodized oil nano-emulsion contrast medium. The method is characterized in that an oil-soluble Fe3O4 nano particles are chosen as an MRI contrast medium part and an oil-soluble CdSe / ZnS quantum dots are chosen as an optical probe part on the basis that iodized oil injection is chosen as a CT contrast medium. Firstly, the oil-soluble Fe3O4 nano particles and / or oil-soluble CdSe / ZnS quantum dots are fully dissolved into the iodized oil injection to serve as an oil phase; the oil phase is added into an aqueous phase containing joint surfactant; stable oil-in-water nano-emulsion is formed with a stirring and ultrasonic emulsification method; and finally, the transparent and clear multiplex-mode iodized oil nano-emulsion contrast medium with proper size, good homogeneity, good stability and high biocompatibility is obtained.

Phase-change-controllable embolic material and preparation method thereof
The invention relates to an embolic material, particularly a phase-change-controllable embolic material applicable to medicine and a preparation method thereof. The phase-change-controllable embolic material is prepared from a temperature-sensitive polymer water solution and a mixed developer, and is characterized in that the mixed developer comprises Iohexol and iodized oil; the mass percent of the mixed developer in the liquid embolic material is 30-80%; and the iodized oil accounts for 3-60% (volume percent) of the embolic material liquid solution. When the ambient temperature reaches the body temperature, the phase-change-controllable embolic material precipitates into solid to perform the embolic function, and the imaging appearance of the solid in the operation is clear, so that the clinician can directly observe and determine the position and flow direction of the embolic material, thereby avoiding ectopic embolism and greatly enhancing the safety of the operation.
