  • Patent number: 11969528
    Abstract: Drug eluting stents, methods of making, using, and verifying long-term stability of the drug eluting stents, and methods for predicting long term stent efficacy and patient safety after implantation of a drug eluting stent are disclosured. In one embodiment, a drug eluting stent may include a stent framework; a drug-containing layer; a drug embedded in the drug-containing layer; and a biocompatible base layer disposed over the stent framework and supporting the drug-containing layer. The drug-containing layer may have an uneven coating thickness. In addition or in alternative, the drug-containing layer may be configured to significantly dissolve/dissipate/disappear between 45 days and 60 days after stent implantation. Stents may reduce, minimize, or eliminate patient risks associated with the implantation of a stent, including, for example, restenosis, thrombosis, and/or MACE.

  • Patent number: 11865129
    Abstract: The present disclosure relates to an application of anemoside B4 in preparation of drug for treatment or prevention of psoriasis. Anemoside B4 has therapeutic effect on 5% imiquimod-induced psoriatic lesions in mice. Its possible mechanism may be inhibiting inflammation reactions, regulating immune function and inhibiting angiogenesis, and the therapeutic effect may be realized by inhibiting the release of IL-12, IL-17, IL-6 and IL-1? in skin tissue. This study of the present disclosure laid a theoretical foundation for the subsequent development of anemoside B4 into an anti-psoriasis drug of traditional Chinese medicine.
