图2 Hb加重缺氧诱导的H9c2心肌细胞损伤 Note： A. Flow cytometry analysis of PI-positive H9c2 cardiomyocytes after hypoxia (1% O₂, 6 h) followed by treatment with different concentrations of Hb for 24 h. B. Quantitative analysis of PI-positive rates in H9c2 cardiomyocytes. C. WST-1 assay to detect the viability of H9c2 cardiomyocytes after hypoxia followed by treatment with different concentrations of Hb. ①P=0.032, ②P<0.001, ③P=0.042, ④P=0.010.
