摘要:
目的 探究调神醒脑针刺法对脑卒中后认知障碍患者炎症反应、应激反应、认知功能及miR-34a、SIRTI等指标的影响,为临床治疗提供新思路。 方法 选取2023年3—9月在华北理工大学附属医院治疗的90例脑卒中后认知障碍患者作为研究对象,根据区组随机法按2:1比例随机分为观察组(60例,调神醒脑针刺法+认知功能训练)和对照组(30例,认知功能训练)。比较2组患者炎症反应[白介素-6(IL-6)、C反应蛋白(CRP)]、应激反应[超氧化物歧化酶(SOD)、丙二醛(MDA)]、认知影响(MESSS)及微小核糖核酸-34a(miR-34a)、血清沉默信息调节因子2相关酶1(SIRT1)的变化。 结果 治疗4周后,观察组MDA [(5.68±0.86) μmol/mL vs. (8.37±1.68) μmol/mL]、MESSS[(14.00±3.00)分vs.(18.00±4.00)分]低于对照组,差异有统计学意义(P < 0.05),而SOD[(126.35±12.37) U/mL vs.(82.38±10.49) U/mL]高于对照组,差异有统计学意义(P < 0.05)。治疗4周后,观察组IL-6[(148.59±29.67) pg/L vs.(209.59±26.37) pg/L]、CRP[(6.19±1.86) mg/Lvs.(10.68±3.67)mg/L]低于对照组,差异具有统计学意义(P < 0.05);观察组miR-34a[(1.16±0.19) vs.(1.46±0.16)]、SIRT1[(1.16±0.22) vs.(0.93±0.18)]低于对照组,差异具有统计学意义(P < 0.05)。 结论 调神醒脑针刺法可改善脑卒中后认知障碍患者的应激反应,减轻炎症反应,降低miR-34a、SIRT1的水平,促进患者认知功能恢复。 -

Abstract:Objective This study investigated the effects of Tiaoshen Xingnao acupuncture on patients with post-stroke cognitive impairment by observing and comparing the changes in inflammatory response, stress response, cognitive function, and the expression levels of miR-34a and SIRT1, with the aim of providing new ideas and approaches for clinical treatment. Methods Ninety patients with post-stroke cognitive impairment treated in the Affiliated Hospital of North China University of Science and Technology from March 2023 to September 2023 were enrolled. Using a block randomization method, they were randomly assigned at a 2:1 ratio to an observation group (60 cases, Tiaoshen Xingnao acupuncture + cognitive function training) and a control group (30 cases, cognitive function training) according to the treatment modalities. The inflammatory response indicators (IL-6, CRP), oxidative stress response (SOD, MDA), cognitive effects (MESSS), and effects on miR-34a, SIRT1 were compared between the two groups. Results After 4 weeks of treatment, MDA [(5.68±0.86) μmol/mL vs. (8.37±1.68) μmol/mL] and MESSS [(14.00±3.00) points vs. (18.00±4.00) points] in the observation group were lower than those in the control group, and the differences were statistically significant (P < 0.05), whereas SOD [(126.35±12.37) U/mL vs. (82.38±10.49) U/mL] was higher than that in the control group, with a statistically significant difference (P < 0.05). After 4 weeks of treatment, IL-6 [(148.59±29.67) pg/L vs. (209.59±26.37) pg/L] and CRP [(6.19±1.86) mg/L vs. (10.68±3.67) mg/L] in the observation group were lower than those in the control group, and the difference was statistically significant (P < 0.05). After 4 weeks of treatment, miR-34a [(1.16±0.19)] was lower than that in the control group [(1.46±0.16)], while SIRT1 [(1.16±0.22) vs. (0.93±0.18)] was higher than that in the control group, and the difference was statistically significant (P < 0.05). Conclusion Tiaoshen Xingnao acupuncture can improve oxidative stress responses, reduce inflammatory reactions, decrease the expression of miR-34a and SIRT1, and promote the recovery of cognitive function in patients with cognitive impairment after stroke. -
