Tanshinone increases Hemopexin expression in lung cells and macrophages to protect against cigarette smoke-induced COPD and enhance antiviral responses.

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disease, while respiratory infections can elicit exacerbations in COPD patients to mediate increased mortality. Administration of Tanshinones (TS) derivatives has been demonstrated to protect against cigarette smoking (CS) and lipopolysaccharide (LPS)-induced COPD progression. However, the underlying molecular mechanisms and the roles of TS in mitigating the severity of viral-mediated exacerbations of COPD have not been elucidated.

The Advances and Biomedical Applications of Imageable Nanomaterials.

Nanomedicine shows great potential in screening, diagnosing and treating diseases.

ROC curves were plotted to evaluate the performance of CT, mpMRI, and CT combined with mpMRI to differentiate pathological subtypes of NSCLC.

Tanshinone IIA protects against chronic obstructive pulmonary disease via exosome‑shuttled miR‑486‑5p.

Chronic obstructive pulmonary disease (COPD) is one of the major causes of death worldwide today, and its related morbidity has been predicted to show an increase in subsequent years. Recent studies have shown that Danshen, a Chinese herbal medicine, is a potential drug in the treatment of inflammation‑related lung diseases. COPD was induced in this study using cigarette smoke (CS) exposure plus intranasal inhalation of lipopolysaccharide to ascertain whether the main pharmacological component from Danshen, tanshinone IIA (TIIA), and its water soluble form, sodium tanshinone IIA sulfonate (STS), protect against the development of COPD.

Cholesterol-induced leucine aminopeptidase 3 (LAP3) upregulation inhibits cell autophagy in pathogenesis of NAFLD.

Objectives: Leucine aminopeptidase 3 (LAP3), an M1 member of leucine aminopeptidase, was reported to be significantly upregulated in serum of nonalcoholic fatty liver disease (NAFLD) patients. However, the underlying mechanisms of LAP3 in NAFLD pathogenesis are still unknown. We aim to investigate the role of LAP3 in NAFLD pathogenesis and explore whether LAP3 has the potential to be a candidate biomarker in serum for NAFLD diagnosis.

A subanesthetic dose of sevoflurane combined with oxygen exerts bactericidal effects and prevents lung injury through the nitric oxide pathway during sepsis.

Volatile anesthetics have been proven to treat experimental sepsis. Sevoflurane combined with oxygen is widely applied in the clinic, and our previous study indicated that this regimen significantly reduced sepsis-induced inflammatory responses and that inhibition of NF-κB pathway activation may contribute to this protection effect. Furthermore, our previous data has shown that sevoflurane combined with oxygen has prevention effect on sepsis-induced lung injury properties and bactericidal properties, but the mechanism is not well understood.

Therapeutic effects of recombinant human brain natriuretic peptide on sepsis-associated encephalopathy in mice.

There is little information in the sepsis treatment guidelines on the prevention and treatment of cognitive dysfunction after sepsis. This study aimed to explore whether Recombinant human brain natriuretic peptide (rhBNP) has protective effects against sepsis-associated encephalopathy (SAE) in a mouse model. The results showed that 50 μg/kg of rhBNP significantly improved the 14-day survival of cecal ligation and puncture (CLP)-induced septic mice and mitigated cognitive dysfunction and anxiety.
