Modification method for improving corrosion resistance and surface functionalization of biomedical magnesium-based metal material

InactiveCN104195535AHigh research and application valuePassive Surface Electrode PotentialMetallic material coating processesSurface functionEndothelial Cell Growth Factor
The invention discloses a modification method for improving corrosion resistance and surface functionalization of a biomedical magnesium-based metal material. The modification method for improving corrosion resistance and surface functionalization of the biomedical magnesium-based metal material comprises the following steps: preparing a Tris-buffer solution with a pH value of 7-12, adding a compound which has a certain concentration and is of a phenolic hydroxyl structure or also adding a compound which has a certain concentration and is of a multi-amino structure. The modification method for improving corrosion resistance and surface functionalization of the biomedical magnesium-based metal material is mild in reaction conditions, simple and easy to operate, relatively low in cost and favorable for after-treatment. The magnesium-based metal material prepared by the method and treated with modified coating has relatively excellent corrosion resistance; by virtue of introduction of different components, a plurality of reactive functional groups can be successfully introduced into the prepared material; the prepared material can be used for subsequent fixation of biological molecules (such as heparin, endothelial cell growth factor VEGF, various types of biological function protein and the like) or introduction of biological functions, is capable of exerting the corresponding biological functions and provides a novel research model for application of magnesium and magnesium alloys to cardiovascular materials.

Method for preparing atomized liquid for treating infantile asthmatic suffocating pneumonia

The invention discloses a method for preparing atomized liquid for treating infantile asthmatic suffocating pneumonia. The atomized liquid comprises gleditsia fruit, loquat leaf, European hop flower, Chinese waxgourd semen, common bluebeard herb, platycodon root, red clover, whiteflower hogfennel root and borneol which serve as raw materials. The method is characterized by comprising the following steps of: (1) extracting the loquat leaf, the European hop flower and the common bluebeard herb by a supercritical fluid extraction method to obtain volatile oil; (2) crushing the gleditsia fruit and the borneol into superfine powder; (3) decocting the red clover, the whiteflower hogfennel root, the Chinese waxgourd semen and the platycodon root in water twice, filtering, mixing filtrates, and concentrating at the temperature of 80 DEG C until the relative density is 1.1 to obtain a water extracting solution; and (4) stirring the volatile oil obtained in the step (1), the superfine powder obtained in the step (2) and the water extracting solution obtained in the step (3) uniformly, standing at normal temperature for 12 hours, and filtering to obtain liquid medicine. Clinical experiments prove that the atomized liquid prepared by the method has an obvious treatment effect, and the hospital stays can be shortened.
