Abstract:
Objective:To investigate the effect of Edaravone and dexborneol(Eda.B)on oxidative stress pathway in peripheral blood of elderly patients with acute ischemic stroke.Methods:A total of 87 elderly patients with acute ischemic stroke in the Department of Neurology, Qinghai University Affiliated Hospital from July 2021 to January 2022 were selected as the study subjects.According to the random number table, they were divided into control group(44 cases)and edaravone dexborneol group(43 cases). Each group was divided into <12 h group, 12-24 h group and 24-48 h group according to the time of onset.Peripheral blood was collected in each group at admission and discharge, respectively.The serum levels of reactive oxygen species(ROS), Kelch-like epichlorohydrin-associated protein 1(Keap1), nuclear factor-E2-associated factor 2(Nrf2), heme oxygenase-1(HO-1), NAD(P)H quinone oxidoreductase 1(NQO1), tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6), as well as superoxide dismutase(SOD)activity and malondialdehyde(MDA)content were detected.Results:Elderly patients with acute ischemic stroke receving Eda.B treatment after admission could reduce the serum concentration of ROS, TNF-α and IL-6, as well as MDA content, and increase the concentration of Keap1, Nrf2, HO-1 and NQO1 and SOD activity.Except for ROS concentration in <12 h group and SOD activity in <12 h and 12 h-24 h groups, the differences between the other groups were statistically significant( P<0.05 for all). Compared with the control group, the serum concentration of TNF-α and IL-6 of patients in the Eda.B group at discharge decreased, while the concentration of Nrf2(24-48 h group)and HO-1(24-48 h group), and SOD activity increased, the differences were statistically significant( P<0.05 for all). In the control group at discharge, the concentrations of ROS(24-48 h group), TNF-α(<12 h group, 24-48 h group)and IL-6, as well as MDA content decreased, while the concentrations of Keap1, Nrf2(<12 h group, 12-24 h group)and HO-1(<12 h group, 12-24 h group)increased, the differences were also statistically significant( P<0.05 for all). Compared with admission, the concentration of Keap1(24-48 h group)and HO-1(24-48 h group), the activity of SOD(<12 h group, 12-24 h group)increased and the content of MDA(12-24 h group)in the Eda.B group decreased at discharge( P<0.05 for all). Conclusions:Eda.B can reduce oxidative stress and inflammatory response in peripheral blood of elderly patients with acute ischemic stroke by acting on the Keap1/Nrf2 pathway.
