摘要目的 探讨短暂性脑缺血发作(TIA)在脑缺血耐受方面的临床意义.方法 选择105例TIA后发生脑梗死的患者为TIA组,并选择110例无TIA史的脑梗死患者作对照组.结果 TIA组和对照组在脑梗死体积(7.68 mm3us11.2 mm3)、治疗前与治疗后15 d、30 d的中国卒中量表评分方面存在统计学差异[(21±3)us(26±5);(14±2)us(20±2);(7±3)us(16±3)]P＜0.05.结论 TIA后发生脑梗死对减轻脑细胞损伤有一定临床意义.

abstractsObjective To analyze the effect of transient ischemie attack(TIA)on cerebral ischemic tolerance.Methods Total 215 cases with cerebral infarction enrolled in our investigation,in which 105 cases had TIA within as TIA group and 110 cases had no TIA history as control group.Results The TIA group had less cerebral infarction volume than control group(7.68 mm3us 11.2 mm3,P＜0.05),and had lower scores in China stroke scale before treatment and after 15 d,30 d treatment[(21±3)us(26±5);(14±2)us(20±2);(7±3)us(16±3)]P＜0.05.Conclusion TIA may improve cerebral ischemic tolerance and it has definite clinical significance for decreasing the injury of brain cells in cerebral infarction.
