Berberine (BBR), an isoquinoline alkaloid originally isolated from the Chinese herb (Huanglian), exhibits anti-inflammatory and immunosuppressive properties. Since myocardial ischemia/reperfusion (I/R) injury is associated with an excessive immune response, the current study was conducted to investigate the impact of BBR on myocardial I/R injury, a common disorder in clinical settings. Preconditioning of Sprague-Dawley rats with BBR (100 mg/kg/day, by gavage) for 14 days prior to the induction of I/R significantly attenuated myocardial I/R injury as manifested by a reduction in the incidence of ventricular arrhythmia and the amelioration of myocardial histological changes. These effects were found to be associated with the suppression of the phosphoinositide 3-kinase/AKT signaling pathway and the subsequent reduction of the expression of interleukin (IL)-6, IL-1β, and tumor necrosis factor-α in the serum and myocardial tissue. These results indicate that BBR has the potential be an effective alternative therapy for the prevention and treatment of myocardial I/R injury in clinical practice.

Electroacupuncture attenuates ferroptosis by promoting Nrf2 nuclear translocation and activating Nrf2/SLC7A11/GPX4 pathway in ischemic stroke.

Objective: Electroacupuncture has been shown to play a neuroprotective role following ischemic stroke, but the underlying mechanism remains poorly understood. Ferroptosis has been shown to play a key role in the injury process. In the present study, we wanted to explore whether electroacupuncture could inhibit ferroptosis by promoting nuclear factor erythroid-2-related factor 2 (Nrf2) nuclear translocation.

Background: Myocardial ischemia/reperfusion (I/R) injury is a common pathophysiological change after myocardial reperfusion therapy. Recent research confirmed that long non-coding RNA (IncRNAs) played an important role in many cardiovascular diseases. This study was carried out to explore the role of lncRNA XR008038 in the I/R progression.

Dihydrotanshinone I (DHT) is an active ingredient derived from Salvia miltiorrhiza. Previous studies have demonstrated that DHT can improve cardiac function in rats with myocardial ischemia-reperfusion injury (IR). However, the mechanism by which DHT improves myocardial injury in rats still requires further research.

Purpose: To investigate the protective effect and mechanism of enhanced expression of endogenous macrophage migration inhibitory factor (MIF) on cardiac ischemia-reperfusion (I/R) injury.

Methods: A recombinant double-stranded adeno-associated virus serotype 9 with MIF or green fluorescent protein (GFP) genes (dsAAV9-MIF/GFP) was transduced into mice and neonatal rat ventricular myocytes (NRVMs). The models of cardiac 60 min ischemia and 24 h reperfusion and 12 h hypoxia/12 h reoxygenation (H/R) were established in mice and NRVMs, respectively.

Purpose: Myocardial ischemia/reperfusion injury (MIRI) is closely associated with ferroptosis. Dexmedetomidine (Dex) has good therapeutic effects on MIRI. This study investigates whether dexmedetomidine (Dex) regulates ferroptosis during MIRI by affecting ferroportin1 (FPN) levels and elucidates the underlying mechanisms.
