Analysis on correlation between RBC and blood lipid indexes in early returning to plain of Han high altitude immigration / 国际检验医学杂志

ABSTRACT

Objective To investigate the changes of red blood cells (RBC) and blood lipid in Han high altitude immigration dur‐ing the process of altitude acclimatization and their correlation .Methods Forty male Han nationality teachers entering Xizang Ali area and working for 1 year were selected .The blood samples were collected before entering plateau and within 3 d after returning to plain .The blood routine and the blood lipid level were detected .Results In the early return to plain ,the RBC ,TG ,CHO and LDL‐C levels in the research subjects were increased ,in which RBC and TG were significantly increased (P< 0 .01) ,HDL‐C was significantly decreased .After returning to plain ,RBC was positively correlated with TG and CHO (r=0 .46 ,P<0 .01 and r=0 .36 , P<0 .05) .Conclusion High altitude hypoxia environment is the primary cause leading to the change of RBC and blood lipid inde‐xes in the plain population after entering the plateau environment .
