[Inhibitive effect of exogenous carbon monoxide-releasing molecules 2 on the activation of Janus kinase/signal transducer and activator of transcription pathway in sepsis].

Objective: To study the inhibitive effect of exogenous carbon monoxide-releasing molecules 2 (CORM-2) on the activation of Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway in sepsis.

Methods: RAW264.7 cells were divided into normal control group, LPS group (10 mg/mL LPS, the same concentration below), LPS + inactive CORM-2 (iCORM-2) group, LPS + 50 mmol/L CORM-2 group, and LPS + 100 mmol/L CORM-2 group.

[Inhibitive effect of exogenous carbon monoxide-releasing molecules 2 on tissue factor expression in sepsis].

Objective: To explore the inhibitive effects of exogenous carbon monoxide-releasing molecules 2 (CORM-2) on expression of tissue factor (TF) in sepsis.

Methods: Human umbilical vein endothelial cells (HUVEC) were cultured with trypsin digestion method, which were divided into NC group (with normal treatment), LPS group (with culture of 10 microg/mL LPS), LD group (with 10 microg/mL LPS and DMSO in co-culture), LC1 group (with 10 microg/mL LPS and 10 micromol/L CORM-2 in co-culture), LC2 group (with 10 microg/mL LPS and 50 micromol/L CORM-2 in co-culture), LC3 group (with 10 microg/mL LPS and 100 micromol/L CORM-2 in co-culture). After culture for 4 hours, TF activity, TF protein expression, nuclear factor-kappaB (NF-kappaB) activity were examined.
