Methods Erythrocytes were collected and prepared into suspensions, and the complex mobility of cells was measured using high performance capillary electrophoresis (HPCE). Optimized experimental conditions were as follows: 50 cm × 75 μm capillary, buffer for electrophoresis; phosphate solution containing hydroxypropylmethyl cellulose (0.1 mol/L, pH 7.4), injection pressure 3.448 kPa, injection time 10 s, separation voltage 20 kV, and column temperature 25 ℃. Results The migration time of erythrocytes in S180 mice was longer than that in normal mice, which was 18.09 min for the model group and 12.11 min for the control group, and the complex mobility of erythrocytes in S180 mice was lower than that in normal mice, which was 0.92 × 104 cm2 /(V·s) for the model group and 1.38 × 104 cm2 /(V·s) for the control group. It was also found that S180 mice treated by QP could shorten the migration time and increase the complex mobility of erythrocytes. Conclusion QP could improve the complex mobility of erythrocytes in S180 mice, and HPCE could be used as a powerful tool for determining the physiological state and functions of erythrocytes.展开更多
