平原人群进入高原环境后,由于大气压降低,氧分压下降,机体供氧不足,可以导致血液中红细胞(RBC)和血红蛋自(Hb)代偿性增多,以增加机体携氧能力,检测结果表现为RBC、Hb、红细胞压积(HCT)等明显增加,且随着海拔高度的增高,缺氧程度加重,RBC和血红蛋白增多更加明显。作者选择进入西藏阿里地区工作(平均海拔5 000m)1年的汉族男性教师40例,分别于进入高原前和返回平原后3日内,检测RYC及三酰甘油(TG)、总胆固醇(CHO)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)。通过统计学相关性分析,旨在探讨高原环境对RBC与血脂指标的影响及两者间的联系。结
Plains into the plateau environment, due to lower atmospheric pressure, decreased partial pressure of oxygen, the body’s lack of oxygen, can cause red blood cells (RBC) and hemoglobin from (Hb) compensatory increase in the body to increase oxygen carrying capacity, the test results Manifested as RBC, Hb, hematocrit (HCT) increased significantly, and as the altitude increased, hypoxia increased, RBC and hemoglobin increased more significantly. The author chose 40 male Han teachers of Han nationality who worked in Ali area of Tibet for one year (with an average elevation of 5000m) for 1 year. RYC, triglyceride (TG) and total cholesterol (CHO) were detected before entering the plateau and within 3 days after returning to plain, Low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C). Through statistical correlation analysis, the purpose of this study is to explore the influence of plateau environment on RBC and blood lipid index and their relationship. Knot
