Analysis of angiographic findings and short-term recurrence factors in patients presenting with hemoptysis.

Objectives: The abnormal anatomical alterations of blood vessels during DSA angiography in patients with hematological disorders were retrospectively examined, and the influencing factors of short-term (≤ 6 months) recurrent hemoptysis were statistically analyzed, and the consistency between admission diagnosis and intraoperative diagnosis was evaluated.

Methods: The intraoperative angiography data of patients who underwent selective bronchial artery embolization for hemoptysis in our hospital from January 2022 to December 2022 were reviewed. They were divided into the observation group and the control group based on whether there was recurrent hemoptysis.

Polynorepinephrine Nanoparticles: A Novel Photothermal Nanoagent for Chemo-Photothermal Cancer Therapy.

Novel photothermal nanoagents (PTNAs) with excellent photothermal performance, smart-responsive property, and biocompatibility are in urgent need for precise chemo-photothermal cancer therapy. Herein, polynorepinephrine nanoparticles (PNE NPs) with a high photothermal conversion efficiency (η) of 808 nm laser (67%), pH/thermal responsibility, and little to no long-term toxicity were synthesized from an endogenic neurotransmitter norepinephrine. Compared to their analogues, polydopamine NPs, a widely used PTNA, PNE NPs exhibited a higher η value (enhanced 1.
