目的:观察碱性成纤维细胞生长因子(basic fibreglass growth factor, bFGF)对大鼠脑出血周边脑组织神经细胞凋亡的影响,并进行相关机制的初步探讨,为进一步深入了解bFGF对脑出血后神经细胞的保护机制的研究奠定基础。方法:通过脑内定位注射胶原酶,建立大鼠脑出血模型;使用假手术组和出血模型组作为对照,采用Zea Longa 5分制评分法对术后大鼠神经功能进行评价,出血模型建立成功的大鼠又分为对照组和bFGF治疗组,bFGF治疗组按8 ug/kg剂量肌内注射;各组分别于术给药后48小时取血肿旁大脑皮质,TUNEL法检测细胞凋亡数目,免疫组化检测p-AKT表达,并对结果进行统计分析。结果:大鼠脑出血模型构建成功;bFGF治疗组与对照组相比,Zea Longa评分显著降低,血肿旁大脑皮质凋亡细胞数量减少,p-AKT表达增高(P < 0.05)。结论:bFGF对大鼠脑出血后周边脑组织具有保护作用,其可能机制是通过提高大鼠脑出血周边脑组织p-AKT的表达来减少神经细胞凋亡数量,从而对脑出血后脑损伤具有保护作用实现。
Objective: To study the influence and regulatory mechanism of the basic fibroblast growth factor (bFGF) on the apoptosis of nerve cells surrounding intracerebral hemorrhage (ICH) in Rat. Methods: The rat model of experimental ICH was established by injection of collagenase VII into internal capsule of cerebrum. Then bFGF treatment group was injected with bFGF 8 vg/kg. After 48 h of treatment, we detected apoptosis of the cerebral cortex near the hematoma by TUNEL, and the phosphorylation level of AKT by immunohistochemistry. Results: Compared with control group, the apoptosis cells surrounding intracerebral hemorrhage of bFGF treatment group were decreased, and the phosphorylation level of AKT was enhanced (
P < 0.05). According to Zea Longa method, the neurological score was decreased in the bFGF treatment group. Conclusion: bFGF could enhance the AKT phosphorylation level and reduce apoptosis of the cells surrounding intracerebral hemorrhage.
