Although this is a common method for clinical treatment of cerebral infarction, whether it promotes the recovery of motor function remains controversial. Twenty patients with cerebral infarction combined with hemiparalysis were equally and randomly divided into a low frequency rTMS group and a control group. The patients in the low frequency rTMS group were given 1-Hz rTMS to the contralateral primary motor cortex with a stimulus intensity of 90% motor threshold, 30 minutes/day. The patients in the control group were given sham stimulation. After 14 days of treatment, clinical function scores （National Institute of Health Stroke Scale, Barthel Index, and Fugl-Meyer Assessment） improved significantly in the low frequency rTMS group, and the effects were better than that in the control group. We conclude that low frequency （1 Hz） rTMS for 14 days can help improve motor function after cerebral infarction.展开更多

文摘目的探究丁苯酞注射液辅治急性脑梗死的临床效果及对脑血管储备功能(cerebrovascular reserve, CVR)、侧支代偿血管建立的影响。方法选取我院2018年2月-2019年1月收治的83例存在手术或溶栓治疗禁忌证的急性脑梗死患者,根据治疗方法的不同分为观察组42例和对照组41例。入院后,两组均给予脑梗死常规治疗,观察组在此基础上加用丁苯酞注射液每日2次静脉滴注,两组疗程均为2周。比较两组治疗前后美国国立卫生研究院卒中量表(national institutes of health stroke scale, NIHSS)评分及Barthel指数(BI),治疗后临床疗效,治疗前后CVR值和脉动指数(PI),治疗后侧支循环建立情况及治疗前后相关因子[血清血管内皮生长因子(VEGF)、重组碱性成纤维细胞生长因子(bFGF)、脑源性神经营养因子(BDNF)]水平,以及治疗期间不良反应。结果与治疗前相比,两组治疗后NIHSS评分降低,而BI升高,且观察组治疗后NIHSS评分、BI改善程度大于对照组,差异均有统计学意义(P<0.05或P<0.01)。治疗后,观察组总有效率为88.10%高于对照组的63.41%(χ2=6.910,P=0.009)。治疗后,两组PI降低、CVR值升高,且观察组PI降低及CVR值升高程度均大于对照组,差异均有统计学意义(P<0.05或P<0.01)。治疗后,观察组侧支循环建立率为61.90%高于对照组的39.02%(χ2=5.633,P=0.012);治疗后,两组血清VEGF、bFGF、BDNF水平均升高,且观察组上述指标升高程度均大于对照组,差异均有统计学意义(P<0.05或P<0.01)。两组治疗期间总不良反应发生率比较差异无统计学意义(χ2=0.862,P=0.353)。结论丁苯酞注射液辅治急性脑梗死的效果显著,可减轻患者神经功能缺损程度,改善生活自理能力,提高CVR,增加侧支代偿血管建立,且治疗安全性良好。
