[The Expression of Sphingosine-1-phosphate and Sphingosine-1-phosphate Receptor 1 in Mouse Model of Pulmonary Ischemia-Reperfusion Injury].

Objective: To investigate the expressions of sphingosine 1-phosphate (S1P) and S1P G-protein-coupled receptor 1 (S1PR1) in pulmonary ischemia reperfusion injury (PIRI) tissues and explore their relationship.

Methods: The model of PIRI was established male C57BL/6 mice (=8). The left pulmonary hilum was occluded for 30 min with a microvascular clamp through a left thoracotomy.

Continuous renal replacement therapy in the treatment of severe acute mountain sickness.

Acute mountain sickness (AMS) is usually seen in unacclimatized individuals ascending to a high altitude within a short period of time. Severe cases may be complicated with multiorgan dysfunction syndrome (MODS), which results in very high mortality. We reported a case of a 20-year-old girl who developed AMS complicated with high altitude pulmonary edema (HAPE), high altitude cerebral edema (HACE), and acute renal failure.
