Study on the Thrombolytic Effect of Platelet Membrane Coated Tenecteplase on Human Arterial Thrombus

Официальное название

Platelet Membrane-coated Tenecteplase to Improve Thrombolytic Efficacy by Targeting Thrombus

Обзор

Tenecteplase (TNK) is the latest generation of specific thrombolytic drugs independently developed in China. This study aims to investigate the thrombolytic efficacy of platelet membrane-coated tenecteplase (PM-TNK) on human ex vivo arterial thrombi, and to explore the inhibitory effects of plasma from patients receiving antiplatelet therapy on its thrombolytic activity, thereby evaluating the future clinical application value of PM-TNK.

Вмешательства

• Другое collection of venous blood or arterial blood
  1\. Partial CAD patients were collected 20 mL arterial blood samples 12 hours after the last intake of 100mg aspirin and 2 hours after intake of 90mg ticagrelor. The blood samples were divided into 2 mL centrifuge tubes, with each containing 1.0 mL (for preparation of blood clots). 2.Partial CAD patients were collected 40 mL blood samples into sodium citrate anticoagulant tubes 12 hours after the last intake of 100mg aspirin and 2 hours after intake of 90mg ticagrelor (for preparation of platele
