Abstract: Embodiments of the present disclosure provide a method for treating developmental dysplasia of the hip. The method includes administering a therapeutically effective amount of a pharmaceutical composition to a subject suffering from the developmental dysplasia of the hip. The pharmaceutical composition includes a substance capable of inhibiting expression of Midkine (MDK), and the substance capable of inhibiting the expression of MDK is Midkine inhibitor (IMDK).

Abstract: A functionalized polyurethane, meniscus prosthesis, the preparation method thereof, and the uses therefor are disclosed. The meniscus prosthesis is manufactured by using polyurethane as the base material and incorporating a self-healing chemical bond, the dynamic dimethylglyoxime-urethane group. Additionally, hyaluronic acid coated with adamantane structures is introduced onto the surface of the self-healing polyurethane elastomer, creating a supramolecular lubricating coating with stress response characteristics. This successfully mimics the dynamic self-healing ability and physiological cyclic lubrication mechanism of natural meniscus, offering a novel solution for the treatment of meniscus injuries and holding great potential value in clinical applications.

Abstract: The present invention provides the use of NAMPT inhibitors in the manufacture of medicaments for preventing and/or treating pigmented villonodular synovitis (PVNS), and belongs to the field of medicine. In the present invention, based on the PVNS-PDX mouse model, it is found that NAMPT inhibitor FK866 exhibits significant therapeutic effects on PVNS, such as improving clinical symptoms related to the disease and inhibiting the proliferation of PVNS grafts. It is discovered that FK866 can target the NAMPT-ITGA5-JUND signaling axis, alleviate endothelial cell damage and vascular permeability, reduce synovial inflammation, decrease the volume of synovial tumor grafts, mitigate hemorrhagic lesions of PVNS, and hinder tumor progression. Therefore, NAMPT inhibitors have broad application prospects in the manufacture of medicaments for preventing and/or treating PVNS.

Abstract: The present disclosure relates to a field of biomedical technology. Embodiments of the present disclosure provide a leonurine nanocomposite hydrogel and preparation method and application thereof, including: dissolving dopamine (DA) monomers and inducing oxidation and self-polymerization of the DA to obtain polydopamine (PDA) nanoparticles, grafting thiol polyethylene glycol folic acid (SH-PEG-FA) on a surface of the PDA nanoparticles to obtain folic acid polydopamine (FA-PDA) nanocarriers; loading a leonurine (Leon) using the FA-PDA nanocarriers of the step 1 to obtain FA-PDA@Leon; encapsulating the FA-PDA@Leon of the step 2 into a gel matrix to obtain gel@FA-PDA@Leon hydrogel.
