Abstract

The invention provides application of a radix physochlainae extract in preparation of drugs for preventing and treating myopia. Effective compositions such as anisodamine, scopolamine and scopoletin in the radix physochlainae extract are obtained through tests, the purpose of preventing and treating myopia can be achieved, and the defect that clinical application cannot be achieved due to potential side effects caused by long-term single use of anticholinergic drugs can be effectively overcome. The radix physochlainae extract has a remarkable treatment effect on myopia, is high in safety, andis expected to be popularized and applied clinically. Experiments prove that the radix physochlainae extract can be used for improving myopia by regulating scleral fibrous layers and retinal pigment cells, influencing expression of matrix metalloproteinase 2, matrix metalloproteinase inhibitor 2 and the like, regulating spasm of ciliary muscles and the like. The invention also provides a composition. The composition comprises effective components of the radix physochlainae extract; and the composition provides a new way for preventing and treating myopia.

Description

technical field [0001] The invention relates to the application and related application of Huashan ginseng extract in the preparation of medicines for preventing and / or treating myopia, and belongs to the technical field of biomedicine. Background technique [0002] The prevalence of myopia among children and adolescents in our country continues to rise, and it is developing towards high incidence and younger age. The number of patients ranks first in the world, and the prevention and treatment of myopia is a worldwide problem. At present, the treatment of myopia includes surgical intervention, drug therapy, optical correction, etc. Surgical treatment is interventional therapy, suitable for low and medium myopia, and has certain damage; drug treatment includes mydriatics, miotics, vasodilators and antispasmodics, etc. , which is mainly used to prevent and treat pseudomyopia, has relatively high potential toxic and side effects, and has a relatively high risk to children and ...
