Major burn injury is associated with systemic hyperinflammatory and oxidative stresses that encompass the wound, vascular, and pulmonary systems that contribute to complications and poor outcomes. These stresses are exacerbated if there is a combined burn and inhalation (B+I) injury, which leads to increases in morbidity and mortality. Nuclear factor-erythroid-2-related factor (NRF2) is a transcription factor that functions to maintain homeostasis during stress, in part by modulating inflammation and oxidative injury. ⋯ When delivered intraperitoneally into mice 1 hour after B+I injury, CDDO-MPs significantly reduced mortality and cytokine dysfunction compared with untreated B-I animals. These data implicate the role of NRF2 regulation of pulmonary and systemic immune dysfunction after burn and B+I injury, and also a deficiency in controlling immune dysregulation. Selectively activating the NRF2 pathway may improve clinical outcomes in burn and B+I patients.

Case Reports
Left Stellate Ganglion Blockade for Refractory Ventricular Arrhythmias With Aconitine Poisoning: A Case Report.
Aconitine poisoning causes refractory ventricular arrhythmias (VAs). In a 20-year-old man, VAs of unknown etiology did not respond to drugs and electrical defibrillation. ⋯ Left SGB is effective for treating refractory VAs with aconitine poisoning and can be easily performed with few complications for VAs of unknown etiology even if patients are receiving anticoagulant therapy. Also, left SGB can be performed to diagnose refractory VAs.
