本文对长期居住在海拔2260m的三组不同人员(自身队员、60岁以上老年人、西宁退休人员)、先后进入到平原的苏州、上海地区、在其前后进行了血液流变学、血凝机制、血小板粘附率、体外血栓形成、纤溶酶原等改变,结果表明,长期移居高原的人,进入到平原后,虽然时间短,但上述指标已有改变,表现在HCT、ηb的下降,高凝状态改善,纤溶亢进减轻,这是“脱适应”的变化,是对氧供环境正常后的一种“再适应”改变,但有些指标改变不明显,除因返回平原时间短外,老年人与中青年人比较,其“脱适应”变化较迟钝。
In this paper, three groups of different long-term residents (own team members, over the age of 60, Xining retired staff) who have long lived in an altitude of 2260m have successively entered the plain areas of Suzhou and Shanghai and conducted hemorheology and hemagglutination mechanism , Platelet adhesion rate, thrombosis in vitro, plasminogen and other changes, the results show that long-term migration to the plateau of people into the plains, although a short time, but the above indicators have changed, the performance of HCT, ηb decline, Hypercoagulable state to improve fibrinolysis hyperthyroidism alleviation, which is “off adaptation” change is a normal oxygen supply for the environment after a “re-adaptation” change, but some indicators change is not obvious, except for a short time to return to the plain, Compared with middle-aged and young people, their “un-adaptation” changes more sluggishly.
