  • Publication number: 20200237925
    Abstract: The present disclosure belongs to the field of pharmaceutical preparations and relates to the design of a series of lipophilic derivatives by using wild-type penetrating peptide penetratin. These penetratin derivatives have a strong ability to penetrate the ocular tissues and do not cause ocular tissue toxicity. As ocular absorption enhancers, non-invasive routes could be used to achieve intraocular drug delivery and increase the ocular bioavailability of drugs. These penetratin derivatives and the ophthalmic drug delivery system constructed by them are used for eye drop administration, which could replace the intraocular injection with poor patients compliance, which greatly enhances the convenience and safety of the treatment of intraocular and fundus diseases.

  • Patent number: 10354625
    Abstract: A digital sight-singing piano is disclosed with a fixed-solfège keyboard, continuous keys and adjustable tones by kneading piano keys, wherein the key can be varied continuously and the frequency of a piano key can be slightly adjusted by kneading the piano key during playing. The keyboard of the digital sight-singing piano has fixed solfège, wherein no matter what key is used for playing, the piano keys in a solfège key set always have the same correspondence to the solfège syllables of the numbered musical notation in one octave. A color graphic vector numbered musical notation is also disclosed, wherein extended solfège is used to describe pitch, different colors are used to indicate the positions of the piano keys to press, notation frames with fixed width are used to represent the beat unit, and font (i.e., bold or not) of musical notes are used to show the strength of pressing piano keys. The color graphic vector numbered musical notation is suitable for computer-aided notation.
