HIF-1α/HO-1-Mediated Ferroptosis Participates in Polystyrene Nanoplastics-Induced Intergenerational Cardiotoxicity.
Nano Lett
January 2025
School of Basic Medical Sciences, Binzhou Medical University, Yantai 264003, China.
To explore the intergenerational cardiotoxicity of nanoplastics, maternal mice were exposed to 60 nm polystyrene nanoplastics (PS-NP) during pregnancy and lactation. The results showed that PS-NP can enter the hearts of offspring and induce myocardial fiber arrangement disorder, acidophilic degeneration of cardiomyocytes, and elevated creatine kinase isoenzymes (CK-MB) and lactate dehydrogenase (LDH) levels after maternal exposure to PS-NP at 100 mg/kg during pregnancy and lactation. Mechanistically, KEGG analysis of RNA sequencing showed the participation of hypoxia-inducible factor-1 (HIF-1) and ferroptosis in PS-NP-induced cardiotoxicity.

Department of Cardiology, Shanghai East Hospital, Tongji University School of Medicine, Shanghai 200120, China. Electronic address:
Purpose: Targeting mitochondrial ferroptosis presents a promising strategy for mitigating myocardial ischemia-reperfusion (I/R) injury. This study aims to evaluate the efficacy of the mitochondrial-targeted ferroptosis inhibitor SS-31@Fer-1 (elamipretide@ferrostatin1) in reducing myocardial I/R injury.
Methods: SS-31@Fer-1 was synthesized and applied to H9C2 cells subjected to hypoxia/reoxygenation (H/R) to assess its protective effects.
Effect of Astragalus injection treatment for viral myocarditis: a systematic review and meta-analysis.
Eur J Med Res
January 2025
Affiliated Hospital of Nanjing University of Chinese Medicine, Nanjing, Jiangsu, China.
Background: Astragalus injection has been utilized in traditional Chinese medicine to treat a variety of diseases. The purpose of this systematic review was to evaluate the effectiveness of Astragalus injection in the treatment of viral myocarditis.
Methods: English databases such as PubMed, Cochrane Library, and EMBASE, and Chinese databases of Sino Med, China National Knowledge Infrastructure (CNKI), the VIP Information Resource Integration Service Platform, and Wanfang Data Information Site, were searched from their inception until May 1, 2024.
Forsythiaside A alleviates myocardial injury in streptozotocin-induced diabetes via endoplasmic reticulum stress-NLRP3 inflammasome pathway.
Int Immunopharmacol
February 2025
Department of Cardiology, The First Affiliated Hospital of Kunming Medical University, Kunming, Yunnan Province, PR China. Electronic address:
The aim of this study was to evaluate for the effects of forsythiaside A (FA) on myocardial injury in streptozotocin (STZ)-induced diabetes mice. Blood glucose (BG), serum triglycerides (TG), lactate dehydrogenase (LDH), creatine kinase isoenzyme (CK-MB), cardiac troponin (cTnI), malondialdehyde (MDA), superoxide dismutase (SOD) levels were detected in STZ mice. The structure and function of heart was observed via cardiac ultrasound.

Remote ischemic preconditioning (RIPC) is reported to have early-phase and delayed-phase organ-protective effects. Previous studies have focused on the organ protection of a single RIPC protocol, and the clinical outcomes remain uncertain. Whether the modified RIPC (mRIPC) protocol performed repeatedly provides cardiopulmonary protection is still uncertain.
