Severe nitrogen oxide poisoning can lead to life-threatening pulmonary injury. we report two cases of severe nitrogen-oxide-induced hypoxia treated with veno-venous extracorporeal membrane oxygenation (ECMO). After exposure, the conditions of both patients continued to deteriorate despite maximal mechanical ventilation with a fraction of inspired oxygen of 100%; therefore, we started veno-venous ECMO. The times from presentation to the initiation of ECMO in the two patients were 1 and 2 days. The hypoxemia and respiratory failure improved quickly after ECMO support. The patients were discharged without complications. The durations of ECMO for the two patients were 5 and 6 days. This report describes how early ECMO support was used to treat potentially fatal pulmonary injury after exposure to nitrogen oxide. The duration of the ECMO run is a critical determinant of patient survival.

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) encompass various etiologies and are distinguished by the onset of acute pulmonary inflammation and heightened permeability of the pulmonary vasculature, often leading to substantial morbidity and frequent mortality. There is a scarcity of viable approaches for treating effectively. In recent decades, acupuncture has been proven to be antiinflammatory.

Pulmonary fibrosis (PF) is a lethal pathological change of fibrotic interstitial lung diseases (ILDs) with abundant fibroblasts proliferation after severely or continually alveolar epithelial cells (AECs) injury. Barely therapies are helpful for PF. Here we use bleomycin intratracheally injection to model PF with or without human umbilical cord-mesenchymal stem cells (hUC-MSCs) and/or nintedanib intervention.

Background: A novel contact force (CF) sensing catheter with a mesh-shaped irrigation tip (TactiFlexTM SE, Abbott), is expected to provide safe and effective radiofrequency ablation. Our previous study revealed that the TactiFlex catheter needs a higher power for pulmonary vein isolation (PVI) due to the long tip length. This study aimed to examine the feasibility and safety of a 50 W ablation with the TactiFlex for PVI of atrial fibrillation (AF).

Introduction: The factors influencing meconium aspiration syndrome (MAS) severity remain poorly understood. In a piglet model of MAS, we hypothesized the respiratory microbiome would reflect the bacterial signature of meconium with short-chain fatty acid (SCFA) accumulation as a byproduct of bacterial fermentation.
Methods: Cesarean section at approximately 115-day term was performed on two sows.
Liver injury in tuberculosis patients, associated with noncompliance with treatment, is further exacerbated by viral hepatitis, which not only directly harms the liver but also increases susceptibility to drug-induced liver injury. The aim of this study was to analyze the associated risk factors for viral hepatitis in tuberculosis patients. This systematic review and meta-analysis adhere to the PRISMA 2020 statement, and the protocol has been registered with PROSPERO (CRD42023477241).
