天降血栓通丸对脑缺血再灌注损伤大鼠线粒体能量代谢的影响
Effects of Tianjiang Xueshuantong pills on mitochondrial energy metabolism in rats with cerebral ischemia–reperfusion injury
目的 观察天降血栓通丸对脑缺血再灌注损伤大鼠的脑保护作用及对线粒体能量代谢的影响。 方法 将30只SD大鼠分为假手术组、模型组、天降血栓通丸组、胞磷胆碱组,采用线栓法建立大鼠大脑中动脉缺血再灌注损伤模型,假手术组与模型组每天给予生理盐水灌胃,天降血栓通丸组给予天降血栓通丸浓缩液灌胃,胞磷胆碱组给予胞磷胆碱片灌胃,每组均干预3 d,采用改良神经功能缺损评分评估大鼠神经功能缺损情况,测量大鼠脑梗死面积,运用尼氏染色和TUNEL染色检测神经细胞损伤程度及凋亡率,利用生物发光法检测大鼠脑组织ATP含量,酶化学法检测Na+-K+-ATP酶活性、Ca2+-Mg2+-ATP酶活性,荧光探针法检测ROS水平。 结果 与模型组比较,天降血栓通丸组与胞磷胆碱组神经功能缺损评分、脑梗死面积均得到有效改善(P<0.05,P<0.01);天降血栓通丸组脑皮质神经细胞尼氏体数量增加,神经细胞凋亡率降低(P<0.01);模型组脑组织中ATP含量显著下降,而ROS含量显著上升,天降血栓通丸组脑组织中ATP含量增加,ROS水平降低(P<0.05,P<0.01);与模型组比较,天降血栓通丸组及胞磷胆碱组脑组织中Ca2+-Mg2+-ATP酶活性、Na+-K+-ATP酶活性均显著提升(P<0.01)。 结论 天降血栓通丸可有效调节MCAO/R模型大鼠脑线粒体能量代谢并发挥脑保护作用。
Objective To observe the neuroprotective effect of Tianjiang Xueshuantong pills on rats with cerebral ischemia– reperfusion injury and their impact on mitochondrial energy metabolism. Methods 30 Sprague-Dawley rats were randomly divided into the sham-operation group, the model group, the Tianjiang Xueshuantong pill group, and the citicoline group. The middle cerebral artery occlusion/reperfusion (MCAO/R) model was established using the intraluminal filament method. The sham-operation group and the model group received intragastric administration of normal saline daily, while the Tianjiang Xueshuantong pill group was given concentrated Tianjiang Xueshuantong pill solution by gavage, and the citicoline group received citicoline tablets by gavage. All groups were treated for three consecutive days. Modified neurological deficit score was used to assess neurological deficit in rats. Cerebral infarct volume was measured. Nissl staining and TUNEL staining were used to detect the degree of neuronal damage and apoptosis rate. ATP content in rat brain tissue was detected using the bioluminescence assay. Na⁺-K⁺-ATPase and Ca²⁺-Mg²⁺-ATPase activities were determined by enzymatic colorimetric methods, and ROS levels were detected using fluorescent probes method. Results Compared with the model group, the Tianjiang Xueshuantong pill group and the citicoline group showed effective improvement in neurological deficit scores and cerebral infarct volume (P<0.05, P<0.01). The number of Nissl bodies in cortical neurons increased and the apoptosis rate of neurons decreased in the Tianjiang Xueshuantong pill group (P<0.01). In the model group, ATP content in brain tissue decreased significantly, while ROS levels increased markedly; After intervention, the Tianjiang Xueshuantong pill group showed increased ATP content and decreased ROS levels in brain tissue (P<0.05, P<0.01). Compared with the model group, both the Tianjiang Xueshuantong pill group and the citicoline group showed significant increases in Ca²⁺-Mg²⁺-ATPase activity and Na⁺-K⁺-ATPase activity in brain tissue (P<0.01). Conclusion Tianjiang Xueshuantong pills can effectively regulate mitochondrial energy metabolism and exert neuroprotective effects in MCAO/R model rats.
