摘要:目的:观察阿托伐他丁对脑梗死大鼠脑保护的作用以及对脑源性神经营养因子(braindeprived neurotrophic factor,BDNF)的影响。方法: 线栓法制备SD大鼠大脑中动脉梗死(middle cerebral artery occlusion,MCAO)再灌注模型。将大鼠随机分为:假手术组;MCAO组的2 h、24 h、3 d、5 d组;阿托伐他丁组的2 h、24 h、3 d、5 d组。MCAO组和阿托伐他丁组的各时程组再分别分为脑梗死体积亚组、免疫组化亚组,每亚组及假手术组各6只大鼠。在不同时间点观察阿托伐他丁组和MCAO组大鼠神经行为评分、脑梗死体积,用免疫组化法检测BDNF阳性细胞数。结果: 神经行为评分和脑梗死体积在阿托伐他丁组和MCAO组的2 h组之间无显著性差异(Pgt;0.05),在阿托伐他丁24 h、3 d、5 d组均显著低于对应时程的MCAO组(Plt;0.05);各组缺血半暗带BDNF阳性细胞数均增高,但阿托伐他丁组的阳性细胞数显著高于对应时程的MCAO组(Plt;0.05)。结论:阿托伐他丁能提高大鼠局灶脑缺血半暗带BDNF的表达水平,促进神经元的修复。Abstract: Objective: To observe the effect of atorvastatin in cerebral protection and braindeprived neurotrophic factor(BDNF) in rats. Methods: Ischemic reperfusion model of rats as established by an intraluminal filament and recirculation at different time point respectively. One hundred and two healthy SD rats were randomly assigned into three groups for different preconditioning, including the sham surgery group (SS, n=6), the sham and middle cerebralartery occlusion (MCAO) group (MCAO, n=48), and the atorvastatin and MCAO group (atorvastatin +MCAO, n=48). The latter two groups were further divided into two subgroups on different time points of tests. Each subgroup hase six rats. In the atorvastatin +MCAO group, intragastric administration of atorvastatin was given for five days, then the MCAO followed. In the MCAO group, the MCAO was given directly. The neurophysical marks and the volume of the cerebral infarction in atorvastatin group and MCAO group were determined at different time point. The expression of BDNF was valued by immunohistochemitry respectively. Results: At 2 h, there were no differences in the neurophysical marks and volume of the cerebral infarction between atorvastatin group and MCAO group (Pgt;0.05). At 24 h,3 d,5 d, the neurophysical marks and volume of the cerebral infarction of atorvastatin group were lower than that of MCAO group in the corresponding time (Plt;0.05). Around the necrotic areas,BDNF positive neurons were increased in both groups, but they were higher in atorvastatin group than in MCAO group in the corresponding time (Plt;0.05). Conclusion: Atorvastatin could increase the expression level of BDNF and promote the ischemic neuron to revive.
目的：研究外伤性脑梗死患者血小板P选择素动态变化的临床意义。方法：用流式细胞仪测定42例外伤性脑梗死患者，50例无脑梗死外伤患者及40例正常对照者外周血血小板P选择素。结果：急性期(1周内)外伤性脑梗死患者P选择素明显高于无梗死脑外伤患者和健康对照组(Plt;0.01)。14 d时，外伤性脑梗死患者血小板P选择素表达，与无梗死脑外伤患者和健康对照组无显著差异(Pgt;0.005)。结论：P选择素参与外伤性脑梗死的病理过程，测定它们有利于外伤性脑梗死的早期诊治，改善预后。
目的:研究疏血通联合奥扎格雷钠治疗进展性脑梗死的临床疗效。方法: 将62例进展性脑梗死患者随机分为两组,对照组30例,治疗组32例。对照组静滴丹参40mL,1/d,羟乙基淀粉40氯化钠500mL,1/d,治疗组静滴疏血通6mL,1/d,奥扎格雷钠160mg,1/d,疗程均为14天。观察两组总有效率及治疗前后神经功能缺损评分、血液流变学、脑血管平均血流速度的改变。结果: 治疗组对进展性脑梗死的总有效率为93.8%,对照组为73.3%,两组相比有显著性差异(Plt;0. 05)。治疗组治疗前后神经功能缺损评分、血液流变学指标、脑血流量均有明显改善,差异有显著性,而对照组则不明显。结论: 疏血通与奥扎格雷钠联合治疗进展性脑梗死能起到协同作用,可有效改善进展性脑梗死患者脑部血液循环,减轻梗死后脑组织的缺血坏死风险,最大程度降低病残率,改善患者的预后,其疗效优于丹参与羟乙基淀粉40氯化钠,且安全性高,是治疗进展性脑梗塞较为理想的药物。
摘要:目的:探讨老年慢性硬膜下血肿术后脑梗死的发病特点及防治措施。方法:总结分析21例老年慢性硬膜下血肿术后出现脑梗死患者。结果:多数患者具有高血压、高血脂、冠心病及糖尿病等多个脑梗死高危因素。术后脑梗死发生于术后1周内者18例,其中3天以内者16例;脑梗死发生于手术区域附近者14例,非手术区域附近者7例,其中5例的脑梗死发生于上述两个区域。结论:脑梗死发病的高危因素是颅脑术后脑梗死发生的主要原因。Abstract: Objective: To investigate and search for the causes of cerebral infarction after operation for subdural hematoma in senile patients and discuss the remedies for its prevention. Methods: Twentyone senile patients with cerebral infarction after operation for subdural hematoma were reviewed retrospectively. Results: Most of the patients were found to be suffered with several risk factors of cerebral infarction such as hypertension, coronary cardiac diseases, diabetes mellitus and so on. Eighteen cases of infarctions occurred within a week after operation, including 16 cases within 3 days. Fourteen cases of the infarctions located in regions around the operative field, while 7 cases in non operation related area, and 5 cases in both areas. Conclusions: Risk factors of cerebral infarction were the main causes to result in cerebral infarction after operation for subdural hematoma.
