  • Patent number: 12433844
    Abstract: A preparation method of a tumor microparticle encapsulating a metabolic inhibitor includes following steps. A tumor cell is cultivated, and a statin drug is added to a culture medium after the tumor cell grows stably. Then, the tumor cell is irradiated with an ultraviolet, and then the tumor cell is incubated in a cell incubator for 22˜26 hours. After the incubation, cell supernatant is collected and the tumor microparticle encapsulating the metabolic inhibitor is obtained through a gradient centrifugation. The preparation method uses tumor cell-derived microparticles as drug delivery platforms, with a simple preparation process that preserves functions such as biosafety, biocompatibility, targeting, and intercellular communication. The preparation method discovers new uses of a statin drug, which can inhibit tumor growths with the statin drug, regulate tumors metabolism and improve a tumor microenvironment, and have a potential to enhance a chemotherapy efficacy and delay a chemotherapy resistance.

  • Publication number: 20240156930
    Abstract: Disclosed is a tumor vaccine based on tumor-derived microparticles (TMPs), and a preparation method and use thereof. The preparation method includes the following steps: 1, subjecting tumor cells to separation to obtain TMPs; 2, mixing the TMPs with 0.03 ?g/?l of a polyethyleneimine solution to allow a reaction for 10 min to 20 min, and washing to obtain PEI-modified TMPs (TMPs-PEI); and 3, mixing the TMP-PEI with 0.1 ?g/?l of a lipopolysaccharide solution to allow cross-linking for 15 min to 1 h to obtain the tumor vaccine based on TMPs (TMP-PEI-LPS). A nanomaterial prepared by conducting surface modification on the TMPs with an immunologic adjuvant can be disguised as a bacterial analog to promote the recognition of tumor antigens in vivo. Moreover, the TMPs can retain their immunostimulatory ability and reduce their toxicity by using a cross-linking agent coupled with the immunologic adjuvant.

  • Patent number: 11546330
    Abstract: Embodiments of the present disclosure provide a method and a device for cross-domain strong logically isolation and secure access control in the Internet of Things (IoT). The method includes the following. When one IoT gateway receives the identity authentication request, the IoT gateway sends the identity authentication request to all IoT gateways in the domain excluding that IoT gateway. When all IoT gateways in the domain receive the identity authentication request, all IoT gateways verify separately whether the identity authentication request is legal. After a certain IoT gateway obtains the identity authentication result, a distributed consensus procedure is initiated. The IoT gateways in the domain reach a consensus on the identity authentication result through a distributed consensus mechanism, and the identity authentication result is written and stored to a block of a blockchain.
