The invention provides a composition for improving the thrombolysis capacity of a human body, a preparation method and application thereof.The composition is prepared from, by weight, 5-30 parts of earthworm protein, 30-120 parts of hippophae rhamnoides total flavone extract, 50-150 parts of silymarin extract, 20-80 parts of maltodextrin and 15-60 parts of pregelatinized starch, the earthworm protein activates a fibrinolytic system to promote t-PA to release and dissolve thrombus, and the hippophae rhamnoides total flavone extract activates the fibrinolytic system to promote t-PA to release and dissolve thrombus; the hippophae rhamnoides total flavonoids regulate the ratio of PGI2 / TXA2 to inhibit platelet aggregation and reduce blood fat, the silymarin protects the liver function to enhance LDL-C metabolism clearing, the hippophae rhamnoides total flavonoids, the silymarin and the hippophae rhamnoides total flavonoids cooperate to form a thrombolysis-antithrombosis-metabolism regulation three-dimensional intervention system, a whole-course low-temperature mixing direct tabletting process is adopted

This invention discloses a protein-inorganic-organic nanocomposite with high thermal stability and its preparation method. The nanocomposite material is prepared by coordinating and self-assembling inorganic and organic components in a solvent. Simultaneously, enzymes and other biomacromolecules are added during the reaction to load the nanocomposite, resulting in the protein-inorganic-organic nanocomposite. The addition of a protein activity protectant during preparation gives the composite extremely high thermal stability; the resulting product maintains its properties under extreme high-temperature conditions above 180°C while effectively preserving the enzyme's biological activity.
