Through the systemic research on the Changes of erythrocytes` metabolism during rats` 7-week treadmill exercise of progressive loading, we got the main results as following: At the beginning of sport, the marrow blood-making reaction which is quickened and strengthened by the sport stimulation recovers after meeting the oxygen demand of the body, and the symbolic quota features are: HGB、RBC、HCT increases, Ret% stays in high amount, LFR and HFR respectively stays in higher and lower level than the nornal ones; without haemolysis, sTfRis a reliable quota for diagnosing iron deficient erythocytes in marrow. It is more sensitive than HEP and also, it can measure the degree of the deficiency after the exhaustion of stored iron; During the sports hemolysis without iron deficiency, sTfR can directly reflects the formation of marrow erythrocytes, which is highly consistent with marrow erythrocytes`s TFR-mRNA presentation, and the changes of serum Epo primarily reflects the tendeney of the formation of marrow erythrocytes. During the primary period of sport, when SF reduces but the level of STFR remains the same, it is probably that the sport-caused high-level blood capacity reaction takes place instead of reducing of iron reserue; when CHr, CVr reduce while Retic%, Retic# and the detailed parameters of them remains the same, or SF reduces and sTfR increases, It is the hint of iron deficient erythrocyte deformation.
通过对七周递增负荷跑台运动大鼠红系细胞变化的系统监测和研究，得出主要结果如下：运动初期，骨髓由于运动应激的影响而加强加快的造血反应在满足了机体氧需求后有所回落，标志性指标特征可为：HGB、RBC、HCT增加，Ret%处于高值，LFR和HFR分别显著高于和低于平常水平；不伴溶血时，sTfR为诊断缺骨髓缺铁性红细胞生成的可靠指标，它比HEP更为敏感，并可量度贮存铁耗竭后继续铁缺失的严重程度；不伴缺铁的溶血发生时，sTFR能直接反映骨髓红细胞的生成情况，其与骨髓细胞TFR-mRNA表达走向高度一致，血清EPO的变化基本反映骨髓红细胞的生成趋势；当网织红细胞数和及分类参数有变动、SF降低，而sTfR不变时，提示高血容量发生；当CHr 和CVr降低，网织红细胞数和及分类参数不变；或者SF降低sTfR增加时，提示缺铁性红细胞生成；当CVr升高，网织红细胞数增加及分类参数变动(表现为高荧光网织红百分比升高)而CHr不变；或者SF不变而sTfR增加时，提示溶血发生；HDW和HDWr、RDWr和RDW等指标的变化可间接反映缺铁性红细胞生成和红细胞溶血的程度。
