Lung-recruited Ly6Chi monocytes had been shown to be involved in ventilator-induced lung injury (VILI). Our present study aimed to investigate whether the cyclooxygenase-2 (COX-2) inhibition modulates the function of lung-recruited Ly6Chi monocytes in a mouse model of VILI. ⋯ Parecoxib-induced alleviation of oxidative stress and inflammation in lung-recruited Ly6Chi monocytes may partly explain the beneficial action of COX-2 inhibition in VILI.

It is still not clear what influences hemoglobin has on the outcomes of patients with sepsis. The intention of this research is to investigate the impact of early hemoglobin levels on clinical outcomes for sepsis. ⋯ Hemoglobin levels at or below 80 g/L in the first 48 h after ICU admission are an alternative indicator for predicting long-term mortality of sepsis. Awareness should be encouraged of the importance of targeting early hemoglobin levels when treating sepsis to improve prognosis.

Our previous study demonstrated the types of platelet dysfunction varied at early stage (∼3 h) in trauma-induced coagulopathy (TIC) caused by different types of injuries. And arachidonic acid (AA)-dependent pathway inhibition in platelet seemed to be specific for TIC caused by multiple injury (MI). The aim of this research was to further study AA-dependent pathway inhibition in platelets in a rat model of TIC caused by MI and to explore its potential mechanisms. ⋯ Platelets inhibition was observed in TIC caused by MI at early stage after injury, which might be partially attributed to AA-dependent activation pathway dysfunction. The increase of plasma Prostacyclin and PGE2 levels may contribute to the inhibition process.
