[Research progress on induced hepatic stellate cell ferroptosis in prevention and treatment of liver fibrosis].

Liver fibrosis is a key pathological stage in the progression of chronic liver disease. If the disease is mistreated, it can further deteriorate into liver failure, which seriously affects the quality of life of patients and brings heavy medical costs. Hepatic stellate cell(HSC) activation triggers extracellular matrix(ECM) deposition, which plays an important driving role in liver fibrosis, and ferroptosis is an effective strategy to clear or reverse the activation of HSCs into a deactivated phenotype.

Pulmonary scedosporiosis in an intractable immunocompetent host: A case report and literature review.
