To study the effect of the combination treatment of ginkgo biloba extract and low-frequency repetitive transcranial magnetic stimulation (LF-rTMS) on the oxidative stress and brain neurotransmitters of patients who had cerebral ischemic stroke (CIS). A retrospective analysis was conducted, and 93 CIS patients admitted to the Sichuan Academy of Medical Sciences/Sichuan Provincial People's Hospital from January 2018 to January 2020 were included in the study. They were divided into three groups, the regular treatment group (31 cases), the LF-rTMS group (31 cases), and the combination treatment group (31 cases). Patients in the regular treatment group were given the conventional drug therapy and exercise regimen. The LF-rTMS group received LF-rTMS therapy (for 20-30 min each time, 1 time/d and 5 times/week) in addition to the treatment given to the regular treatment group. The combination treatment group was given ginkgo biloba extract (intravenous drips, once per day) in addition to the treatment given to the LF-rTMS group. The treatment was given continuously for 4 weeks and comparison was made at the end of the 4-week treatment regarding the clinical efficacy, oxidative stress response, cerebral oxygen metabolism, and brain neurotransmitter as shown by the three groups. The treatment efficacy in the combination treatment group (96.77%) was higher than those of the LF-rTMS group (80.65%) and the regular treatment group (54.84%). The LF-rTMS group showed higher treatment efficacy than that of the regular group. The serum superoxide dismutase (SOD) of the combination treatment group was higher than that of the LF-rTMS group and that of the routine group, while the malondialdehyde (MDA) and endothelin-1 (ET-1) of the combination treatment group were lower than those of the LF-rTMS group and the regular treatment group ( P<0.05). The serum SOD of the LF-rTMS group was higher than that of the regular treatment group, while the MDA and ET-1 of the group was lower than those of the regular treatment group ( P<0.05). The arterial oxygen content (CaO 2), arterio-venous oxygen content difference (Ca-vO 2) and cerebral extraction rate of oxygen (CERO 2) in the combination treatment group were lower than those of the LF-rTMS group and the regular treatment group ( P<0.05). The levels of these three indicators of the LF-rTMS group were lower than those of the regular treatment group ( P<0.05). EEG frequencies of gamma-aminobutyric acid (GABA), 5-hydroxytryptamine (5-HT) and dopamine (DA) of the combination treatment group were higher than those of the LF-rTMS group and the regular treatment group, while the acetylcholine (Ach) EEG frequency of the combination treatment group was lower than that of the LF-rTMS group and regular treatment group ( P<0.05). The LF-rTMS group showed higher GABA, 5-HT and DA EEG frequencies than those of the regular treatment group, while the Ach EEG frequency of the group was lower than that of the regular treatment group ( P<0.05). All the patients were followed up for 6 months, and recurrence rate was lower in the combination treatment group (3.23%) than that of the LF-rTMS group (19.35%) and the regular treatment group (25.81%) ( P<0.05). The combination treatment of ginkgo biloba extract and LF-rTMS helped to improve the clinical outcome of CIS patients, which may be related to the inhibition of oxidative stress, improvement in cerebral oxygen metabolism, and regulation of brain neurotransmitter.
