Paraquat is an organic heterocyclic herbicide that is widely used in agriculture, especially in Asian countries. The prevalence of paraquat poisonings has increased dramatically in the past two decades in China. Nearly all paraquat poisonings resulted from intentional or accidental oral administration leading to acute lung injury and, ultimately, acute respiratory distress syndrome. The mortality rate has been reported to be greater than 90%. However, the exact toxic mechanism remains unclear. Herein, we reviewed and summarized the most recent publications related to the molecular mechanisms of paraquat-induced acute lung injury.

Background: is a differentially expressed gene (DEG) between M1 and M2 macrophages. This study explained why it causes opposite effects in different circumstances.
Methods: Gene expression profiles of various cell subsets were compared by mining a public database.

Background: Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have shown benefits in improving cardiovascular (CV) outcomes in patients with heart failure (HF) and may mitigate symptom progression in myocardial infarction (MI). However, their effectiveness in patients with type 2 diabetes and MI undergoing percutaneous coronary intervention (PCI) is unclear.
Methods: To identify eligible studies, a comprehensive search of electronic databases, PubMed, Cochrane Library, Scopus and Embase, was conducted from inception until May 2024.

Papillary fibroelastomas (PFEs) are rare, benign, primary cardiac tumors, typically found on the valve surfaces and more commonly on the left side of the heart, with occurrences in the right atrium even rarer. In this case, a highly mobile tumor was incidentally detected in the right atrium of an 83-year-old woman with advanced right lung cancer during preoperative transthoracic echocardiography and magnetic resonance imaging. Although the patient was asymptomatic and of advanced age, the tumor's high mobility warranted resection.

Despite the established anti-fibrotic effects of mesenchymal stem cells (MSCs), numerous challenges hinder their clinical application. A recent study demonstrated that microvesicles (MVs) from MSCs (MSC-MVs) could attenuate ARDS-related pulmonary fibrosis and enhance lung function hepatocyte growth factor mRNA transcription.

Acute respiratory distress syndrome (ARDS) is a clinical syndrome of acute hypoxic respiratory failure caused by diffuse lung inflammation and edema. ARDS can be precipitated by intrapulmonary factors or extrapulmonary factors, which can lead to severe hypoxemia. Patients suffering from ARDS have high mortality rates, including a 28-day mortality rate of 34.
