摘要

临床试验中以体重为基础的溶栓用药策略在再通率和溶栓后出血方面存在严重缺陷。精确溶栓迫切需要检测溶栓阻力的血栓异质性的方法。在这里，我们揭示了凝血酶异质性与血栓中溶栓阻力之间的关系，并创建了一个基于生物标志物的人工纳米巡逻系统，该系统具有机器人功能逻辑，可以感知和报告血栓的溶栓阻力。纳米巡逻队是可控的，能够根据人工生物标志物的反馈信号完成与溶栓阻力匹配的个性化精确治疗。与阿替普酶相比，该纳米巡逻系统对迷你猪模型和临床血栓的溶栓效率提高了25%，并在阿替普酶失效的血栓模型中实现了再通。此外，纳米巡逻显著降低了脑血栓的梗死面积和出血转化风险（阿替普酶的0.12倍）。因此，我们开发了一种独特的工具来诊断溶栓抵抗并实现个性化和精确的溶栓。

Artificial biomarker-based feedback-regulated personalized and precise thrombolysis with lower hemorrhagic risk

The body weight–based thrombolytic medication strategy in clinical trials shows critical defects in recanalization rate and post-thrombolysis hemorrhage. Methods for perceiving thrombi heterogeneity of thrombolysis resistance is urgently needed for precise thrombolysis. Here, we revealed the relationship between the thrombin heterogeneity and the thrombolysis resistance in thrombi and created an artificial biomarker-based nano-patrol system with robotic functional logic to perceive and report the thrombolysis resistance of thrombi. The nano-patrols are contrallable and are able to accomplish thrombolysis resistance-matched personalized and precise therapy according to the feedback signal from artificial biomarkers. This nano-patrol system depicted more enhanced thrombolytic efficiency (elevated by 25%) than alteplase for mini pig model and clinical thrombi and achieved recanalization in thrombotic model where alteplase encountered failure. Moreover, the nano-patrol remarkably reduced the infarct volume and the hemorrhagic transformation risk (0.12-fold of alteplase) of cerebral thrombosis. Therefore, we developed a unique tool for diagnosing thrombolysis resistance and achieving personalized and precise thrombolysis.
