Objective:To observe the effect of JQYXKL on the hematopoiesis and physical strength in Qi-Xue deficiency mice.Methods: Qi-Xue deficiency in mice was mimicked by directly drawing blood once and forced swimming consecutively for 7 days.Routine blood test was performed for the hematopoiesis analysis.Serum EPO was detected by ELISA methods.Results: After blood drawing and consecutively swimming for 7 days

the red blood cells and hemoglobin concentration decreased comparing with control animals.The same time serum EPO increased after insults.Treatment with JQYXKL enhances the red blood cell and hemoglobin in red blood cells.The swimming time was also increased after JQYXKL treatment.We also found that JQYXKL could further increase the serum EPO of insulted mice.Conclusion:JQYXKL could improve the physical strength of Qi-Xue deficiency mice.It also enhances the blood cells number and hemoglobin concentration

which might come from the effect of improved EPO level.
