Abstract: 【Objective】 This study was aimed to explore the preparation method of rat hepatocyte (BRL-3A) oxidative stress model induced by sodium hydrosulfite (Na2S2O4), in order to establish a stable oxidative stress model of BRL-3A cells.【Method】 The medium containing Na2S2O4 was used to cause hypoxia of cells, and the normal medium was replaced to reoxygenate BRL-3A cells, thus causing oxidative stress damage of cells.BRL-3A cells were divided into 5 groups, and the control group was cultured normally in a cell incubator (0 mmol/L Na2S2O4), the experiment group was treated with different concentrations (0.1, 1, 5 and 10 mmol/L) of Na2S2O4 for 4 h of hypoxia and 2 h of reoxygenation, then the cell viabiliaty rate was detected by CCK-8 assay.The fluorescent probe DCFH-DA method was used to detect the release of reactive oxygen species (ROS) in cells.The activity of lactate dehydrogenase (LDH) in cell culture medium, the contents of malondialdehyde (MDA) and glutathione (GSH), and the activity of superoxide dismutase (SOD) in BRL-3A cells were detected by kit.【Result】 After hypoxia/reoxygenation treament, compared with blank control group, with the increase of Na2S2O4 concentration, the viability rate of BRL-3A cells was gradually decreased (P<0.01), the release of ROS was gradually increased (P<0.01), the activity of LDH and the content of MDA were increased in a concentration dependent manner (P<0.01), the content of GSH and the activity of SOD were decreased in a concentration dependent manner (P<0.05 or P<0.01).【Conclusion】 This study showed that a stable oxidative stress model of BRL-3A cells could be established which was induced by 5 mmol/L Na2S2O4 for hypoxia of 4 h and reoxygenation of 2 h.
