Aggregate-induced emission luminogens(AIEgens) have been widely used in biological imaging, chemical sensing, and disease treatments. The rational design and construction of AIEgens have received considerable research interests during the last few years. Herein, molecular docking-aided AIEgen design has been reasonably proposed and AIEgen TBQZY with excellent ~1O_(2) generation ability has been synthesized. The newly developed TBQZY could efficiently kill S. epidermidis and methicillinresistant S. epidermidis(MRSE) by tightly binding to bacteria and triggering the accumulation of ~1O_(2) in bacteria. TBQZY specifically regulated the immune system and polarized macrophages from M1 to M2 to accelerate the elimination of biofilm in vivo. In addition, healing acceleration was observed in chronic wounds treated with TBQZY, and side effects were ***, TBQZY had extraordinary potential for combating drug-resistant bacteria in the clinical setting. This research not only provided new concepts for the design of AIEgens, but also shed some lights on the discovery of drugs against drug-resistant bacteria.

Conquer coronary artery perforation with magic hands

Journal of Geriatric Cardiology 2024年第4期21卷 379-386页

作者： yi-Lun zou Jian-Qiang LI Ding-Yu WANG Yong-Tai GONG Li SHENG Yue LI Department of Cardiology the First Affiliated Hospital of Harbin Medical UniversityHarbinChina

Coronary artery perforation(CAP) poses a significant challenge for interventional cardiologists. Management of CAP depends on the location and severity of the perforation. The conventional method for addressing the perforation of large vessels involves the placement of a covered stent, while the perforation of distal and collateral vessels is typically managed using coils, autologous skin, subcutaneous fat, microspheres, gelatin sponge, thrombin or other substances. However, the above techniques have certain limitations and are not applicable in all scenarios. Our team has developed a range of innovative strategies for effectively managing CAP. This article provides an insightful review of the various tips and tricks for the treatment of CAP.
