Sinomenine attenuates septic-associated lung injury through the Nrf2-Keap1 and autophagy.

Objectives: Our present study focused on assessing whether Sinomenine (SIN) could attenuate sepsis-induced acute lung injury (ALI).

Methods: The mice were conditioned with SIN 1 h before intraperitoneal injection of lipopolysaccharide (LPS). Lung wet/dry (W/D) ratio, inflammatory level in bronchoalveolar lavage fluid (BALF), malondialdehyde (MDA) levels, superoxide dismutase (SOD) activity and inflammatory cytokines production were detected.

Sini decoction ameliorates sepsis-induced acute lung injury via regulating ACE2-Ang (1-7)-Mas axis and inhibiting the MAPK signaling pathway.

Sepsis, as life-threatening organ dysfunction caused by a dysregulated host response to infection, is characterized by the extensive release of cytokines and other mediators. Sini decoction (SND), a traditional Chinese prescription medicine, has been used clinically for the treatment of sepsis. But its explicit mechanism of action is still unclear.

Sinomenine protects against E.coli-induced acute lung injury in mice through Nrf2-NF-κB pathway.

Acute lung injury (ALI) is a common disease characterized by pulmonary inflammation and oxidative stress. Sinomenine (SIN) is an alkaloid originally extracted from the Chinese medicinal plant Sinomenium acutum. It has been shown to have anti-inflammatory and anti-oxidative effect.

Sini decoction alleviates E. coli induced acute lung injury in mice via equilibrating ACE-AngII-AT1R and ACE2-Ang-(1-7)-Mas axis.

Aims: Acute respiratory distress syndrome (ARDS), one of the serious form of acute lung injury (ALI), is the primary cause of death in patients with ALI. Sini decoction (SND) is a widely used Traditional Chinese Medicine (TCM). However, the application of SND in ALI is rarely reported.
