中文摘要
我们已经在体外炎症模型中评估了矿皮质激素和糖皮质激素的时间和剂量的影响。我们的方法包括多重阵列、聚合酶链反应基因扩增和微阵列分析。地塞米松(一种纯糖皮质激素)、醛固酮(一种矿皮质激素)和脱氧皮质酮(一种纯矿皮质激素激动剂)对内毒素激活的内皮细胞具有根本不同的炎症调节作用。我们目前正在评估这些分子在信号通路和基因表达中的相互作用。这些数据将有助于了解它们在脓毒性休克引起的严重低血压患者中的临床效果。
英文摘要
We have assessed the effects of time and dose of mineralocorticoids and glucocorticoids in an in vitro model of inflammation. Our methods include multiplex arrays, gene amplification with polymerase chain reaction, and microarray analysis. Dexamethasone (a pure glucocorticoid) and aldosterone (a mineralocorticoid) and deoxycorticosterone (a pure mineralocorticoid agonist) have fundamentally different inflammatory modulating effects on endothelial cells that are activated with endotoxin. We are currently assessing interactions of these molecules on signaling pathways and gene expression. These data will help to provide some insights into their clinical effects when used in patients with severe hypotension from septic shock.
