  • Publication number: 20240053955
    Abstract: This application provides a hearing monitoring method and apparatus. The method includes: obtaining ear overuse information of a user, where the ear overuse information includes accumulated duration and/or accumulated times of overuse of ears of the user; and generating prompt information or a control instruction based on the ear overuse information. In this solution, because accumulated information is obtained, impact of a misoperation of the user can be excluded, and continued overuse of ears is also fully detected. Therefore, an unnecessary or missed reminder is avoided, thereby achieving more accurate hearing monitoring effect.

  • Publication number: 20230414643
    Abstract: The present disclosure discloses a preparation method of ginseng composition with high ginsenoside bioavailability. The composition is composed of ginseng powder of 250 meshes or more and ?-cyclodextrin, and the mass ratio of the ginseng powder to the ?-cyclodextrin is 1:0.05. Results show that when ?-cyclodextrin is used as a solid dispersant and added to the 1000-mesh ginseng powder at a mass ratio of 5%, the total dissolution amount is maximum; and furthermore, animal experiments (SD rats) show that the area under the plasma drug concentration-time curve (AUC0-48 h) after 48 h of ginseng powder ingestion is maximum, indicating that in-vivo bioavailability of the ginseng powder is the highest. The method of this application can effectively inhibit the aggregation of the ultra-finely pulverized 1000-mesh ginseng powder by adding the ?-cyclodextrin, thus significantly improving the total dissolution amount of ginsenoside.
