Aims: The NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome, which is activated by reactive oxygen species (ROS) and repressed autophagy, has been identified as a novel agent of pulmonary fibrosis. Angiotensin II (AngII), the bioactive pro-oxidant in renin–angiotensin system, aggravates lung However, effect AngII on NLRP3 inflammasome autophagy fibrosis remains unknown. This study investigates potential link between AngII-induced regulation inflammasome/IL-1β axis...

Recent studies suggested that the gray-white matter ratio (GWR) determined from brain computed tomography (CT) scans may be a reliable predictor of poor neurological outcomes. The aim study was to evaluate association between GWR and outcomes in adult comatose cardiac arrest (CA) survivors Chinese.A total 58 CA patients who had CT within 72 h resuscitation January 2011 December 2015 were included this single-center retrospective study. Gray white attenuations (Hounsfield units) measured,...

Cigarette smoking is acknowledged as the major risk factor of pulmonary fibrosis. Angiotensin (Ang) II has been reported to aggravate smoking-induced lung fibrosis, whereas effect Ang-(1-7) on smoking-related fibrosis remains unknown. The autophagy, being activated by reactive oxygen species (ROS), identified a novel mechanism However, whether autophagy involved in regulation still needs investigation. Here, we aim investigate and ROS. In vivo, was constantly infused into passive rats for 8...

sophageal cancer is the fourth most common in China with five-year survival rates ranging from 15% to 40% (1-3).Patients early-stage esophageal are usually treated endoscopic submucosal dissection (ESD) or esophagectomy.However, for patients unresectable advanced who cannot tolerate esophagectomy, chemoradiation therapy (CRT) a priority.CRT prolonged lifetime of many cancer, but some benefit it, which depends on patients' response (4).Meanwhile, side effects caused by CRT including bone...
