Abstract:Objective To investigate the effect of butylphthalide soft capsule combined with acupuncture on stellate ganglion in the treatment of posterior circulation ischemia (PCI) and its intervention on oxidative stress mechanism.Methods From March 2016 to March 2019, 128 patients with PCI in Cangzhou integrated traditional Chinese and Western Medicine Hospital of Hebei Province were selected and randomly divided into 4 groups with 32 cases in each group. The control group A was treated with butylphthalide soft capsule, the control group B was treated with acupuncture at stellate ganglion, and the observation group was treated with butylphthalide soft capsule combined with acupuncture at stellate ganglion. The serum levels of MDA, SOD, and cat were detected by ELISA. The relative expression of microRNA-21 (miR-21) and microrna-146a (miR-146a) mRNA was detected by real-time fluorescent quantitative polymerase chain reaction (qRT-PCR). The clinical total effective rate, NIHSS score, Barthel index, blood flow velocity and cerebrovascular resistance of internal carotid artery (ICA), vertebral artery (VA), basilar artery (BA), oxidative stress index [serum malondialdehyde (MDA), superoxide dismutase (SOD), and catalase (CAT)], the relative expression of miR-146a mRNA, and the incidence of adverse reactions were compared among the four groups.Results The clinical efficacy of the observation group (90.63%) was higher than that of the control group A (68.75%), the control group B (65.63%), and the blank control group (43.75%). After the treatment, the NIHSS score of the observation group was lower than that of the control group A, the control group B, and the blank control group; the Barthel index of the observation group was higher than that of the control group A, the control group B, and the blank control group (P < 0.05); After the treatment, the blood flow velocity of ICA, VA and BA in the observation group was higher than that in the control group A, control group B, and blank control group; the relative expression levels of cerebrovascular resistance, serum MDA, miR-21 and miR-146a mRNA in the observation group were lower than those in the control group A, control group B, and blank control group; the levels of SOD and cat in the observation group were higher than those in the control group A, control group B, and blank control group (P < 0.05).Conclusions Butylphthalide soft capsule combined with acupuncture at stellate ganglion can improve cerebral blood circulation and nerve function, inhibit oxidative stress, and improve the ability of daily life of patients with PCI.
