Methods Six gradient concentrations of H2 O2 were co-cultured with HUVECs for 6 h, 12 h, 24 h and 48 h. Inverted microscope was used to observe the change of cell morphologies. The optimal working concentration and effect time of H2 O2 on HUVECs were screened by CCK-8 method for cell viability, flowcymetry for apoptosis rate, and CDFU-DA fluorescent probing and flowcymetry for ROS levels. Re s ults Any concentration of H2 O2 could do harm to HUVECs co-culturing with cells. Cell viabilities decreased statistically when treating cells with 400, 600 or 800 μmol/L H2 O2 for different times (P<0.05) . Cell viabilities also decreased gradually as time prolonged when treating cells with 800 μmol/L H2 O2 (P<0.001) . When treating cells with different concentration of H2 O2 for 24 h, cell apoptosis rates increased dramatically (1000μmol/L as an exception, P<0.05) , so did cell necrosis rates (100 μmol/L as an exception, P<0.05) ;When treating cells with 800 μmol/L H2 O2, cell apoptosis rates increased dramatically as time prolonged, reaching the peak at 24 h (P<0.05) , so did necrosis rates, reaching the peak at 48 h (P<0.05) . ROS level reached thepeak while treating cells with 400 μmol/L H2 O2 (P<0.001) ; ROS levels increased gradully as time prolonged when treating cells with 800 μmol/L H2 O2 (P<0.001) . Conclusions The oxidative stress model in HUVECs was established by coculturing cells with culture medium containing 800 μmol/L hydrogen peroxide for 24 h.
