[Abstract]
Objective Based on nuclear transcription factors- κB (NF- κB) p65 signaling pathway to explore the efficacy of argatroban combined with alteplase in treatment of acute ischemic stroke and its impact on depression related indicators. Methods A total of 164 patients with acute ischemic stroke without thrombolytic contraindication treated in Xingtai Third Hospital from November 2019 to June 2020 were prospectively selected as the research objects. The patients were randomly divided into control group and experimental group, with 82 cases in each group. Patients in both groups were given intravenous thrombolysis with ateplase, and Clopidogrel Bisulfate was given 24 hours after thrombolysis. Patients in the experimental group were given intravenous infusion of Argatroban Injection 24 hours after thrombolysis on the basis of the control group, and the treatment lasted for four weeks. The levels of activated partial thromboplastin time (APTT) were measured before treatment, immediately after the completion of thrombolytic therapy with ateplase for injection, three hours after the end of thrombolytic therapy, and 48 hours after the end of thrombolytic therapy. The National Institutes of Health stroke scale (NIHSS), Hamilton depression scale (HAMD), mini mental state examination scale (MMSE) and activity of daily living scale (ADL) were used to evaluate the efficacy of two groups. Serum mRNA expression of NF-κB p-p65 and p65, p-IκBα and IκBα were detected by real-time fluorescent quantitative PCR (qRTPCR) before and after treatment. During and after treatment, cerebral hemorrhage, decreased hemoglobin (< 100 g·L-1), prolonged APTT (> 53 s) and other complications were observed in two groups. Results Before treatment, there was no significant difference in APTT between two groups (P > 0.05). Compared with before treatment, APTT was significantly prolonged in both groups immediately after the end of thrombolytic therapy and three hours after the end of thrombolytic therapy (P < 0.05). Compared with that before treatment, APTT in experimental group basically returned to normal 48 hours after thrombolytic treatment, but it was still significantly prolonged in the control group (P < 0.05). Compared with the control group, the total effective rate of the experimental group was higher (P < 0.05). Compared with the control group, the number of cases of decreased hemoglobin and prolonged APTT in experimental group was slightly lower than that in control group after treatment, but the difference was not statistically significant (P > 0.05). Before treatment, there was no significant difference in NIHSS, HAMD, MMSE and ADL scores between two groups (P > 0.05). After one and four weeks of treatment, NIHSS and HAMD score in control group and experimental group decreased significantly (P < 0.05), and NIHSS and HAMD score in experimental group were lower than those in control group (P < 0.05), while MMSE and ADL score increased significantly (P < 0.05), and MMSE and ADL score in experimental group were higher than those in control group (P < 0.05). After treatment, The expression level of serum NF-κB p-p65, NF-κB p65, NF-κB p-IκBα, NF-κB IκBα of two groups was significantly lower than that before treatment (P < 0.05), and after treatment, the expression level of NF- κB p-p65, NF-κB p65, NF-κB p-IκBα, NF-κB IκBα in experimental group was significantly lower than that in the control group (P < 0.05). Conclusion 24 hours after intravenous thrombolysis with ateplase combined with argatroban anticoagulation in patients with acute ischemic stroke, the curative effect is significant and the complications are less. Argatroban can controllably affect the coagulation function of patients, improve the neurological function and cognitive function of patients, and reduce the occurrence of post-stroke depression by regulating on NF-κB p65 signaling pathway.
