目的 :高原缺氧性肺动脉高压形成的主要因素有缺氧性肺动脉收缩和缺氧性动脉壁构型重建。肺动脉平滑肌细胞的增殖是缺氧性肺动脉壁构型重建的重要环节。药用植物红景天甙具有抗缺氧、提高机体对高原的适应能力等作用 ,在我国西北、西南高原缺氧地区被用于防治高原适应不全症 , Objective : The main factors for the formation of hypoxic pulmonary hypertension at high altitude are hypoxic pulmonary artery contraction and hypoxic arterial wall remodeling. Pulmonary arterial smooth muscle cell proliferation is an important part of hypoxic pulmonary artery wall reconstruction. The medicinal plant, Rhodiola sauteri, has anti-hypoxia and increased body adaptability to the plateau. It was used to control altitude sickness insufficiency in the areas of hypoxia in the northwest and southwest of China.
