The invention provides a preparation method of a pH-responsive quick self-repairing collagen-based hydrogel with adhesivity, antibiosis and pressure resistance. The preparation method comprises the following steps: S1, weighing PEG 2000, 4-formylbenzoic acid and dimethylaminopyridine, dissolving in tetrahydrofuran, adding N, N'-dicyclohexylcarbodiimide in a nitrogen atmosphere, stirring, and then filtering to obtain a white solid; dissolving the white solid in tetrahydrofuran, precipitating in diethyl ether, drying to obtain DA-PEG, and dissolving in water to prepare a DA-PEG solution; S2, weighing and mixing a prepared collagen solution with a chitosan solution, wherein the mass ratio of the collagen solution to the chitosan solution is 3: 1-1: 3 to obtain a collagen/chitosan mixed solution; S3, adding a DA-PEG solution into the collagen/chitosan mixed solution under an ice bath condition to prepare a collagen/chitosan/DA-PEG mixed solution, adjusting the pH value to be 3.6-4.8, and uniformly mixing; and standing to obtain the pH-responsive quick self-repairing collagen-based hydrogel with adhesiveness, antibiosis and pressure resistance.

The invention relates to a traditional Chinese medicine composition for treating porcine encephalitis and a preparation method of the traditional Chinese medicine composition. The traditional Chinese medicine composition comprises the following ingredients in parts by weight: 10-20 parts of radix curcumae, 5-10 parts of semen platycladi, 10-20 parts of Herba Lophatheri, 5-10 parts of fructus forsythiae, 10-20 parts of Flos Chrysanthemi, 10-15 parts of cortex moutan, 10-15 parts of rhizoma acori graminei and 10-15 parts of rhizoma anemarrhenae. The traditional Chinese medicine composition for treating the porcine encephalitis has effects of antibiosis, anti-inflammation and intracranial pressure reduction, and small toxic and side effects, is free from medicine residue, has low possibility of medicine resistance, is easy to absorb, high in bioavailability and convenient to use, meets requirements of safe veterinary medicine and animal-origin food safety guarantee and is relatively ideal.
