文题释义:
依达拉奉:
是一种自由基清除剂。大鼠在缺血/缺血再灌注后静脉给予依达拉奉,可阻止脑水肿和脑梗死的进展,并缓解所伴随的神经症状,抑制迟发性神经元死亡。机制研究提示,依达拉奉可清除自由基,抑制脂质过氧化,从而抑制脑细胞、血管内皮细胞、神经细胞的氧化损伤。
脑梗死:又称缺血性卒中,系由各种原因所致的局部脑组织区域血液供应障碍,导致脑组织缺血缺氧性病变坏死,进而产生临床上对应的神经功能缺失表现。脑梗死依据发病机制的不同分为脑血栓形成、脑栓塞和腔隙性脑梗死等主要类型。

 

摘要
背景:
抑制血清炎性因子凝血酶元激活因子的抑制因子1和组织纤维溶酶原激活物表达是治疗脑梗死的潜在靶点之一。
目的:观察骨髓间充质干细胞移植联合依达拉奉对脑梗死大鼠血清炎性因子的表达变化。
方法:60只SD大鼠采用大脑中动脉线栓法复制局灶性脑梗死模型后,随机等分为模型组、骨髓间充质干细胞移植组和联合组。模型组连续 5 d尾静脉注射PBS,骨髓间充质干细胞移植组经尾静脉注射 2.0×109 L-1骨髓间充质干细胞悬液1 mL,2次/d,连续 5 d。联合组静脉滴注依达拉奉30 mg+尾静脉注射 2.0×109 L-1骨髓间充质干细胞悬液1 mL(2次/d),连续 5 d。
结果与结论:①与模型组相比,骨髓间充质干细胞移植组与联合组大鼠mNSS评分较低,血清凝血酶元激活因子的抑制因子1表达水平减少,脑梗死面积减少,脑组织中肿瘤坏死因子αmRNA的表达水平减少;②联合组大鼠上述指标变化差异比骨髓间充质干细胞移植组大;③结果提示骨髓间充质干细胞移植联合依达拉奉有助于促进脑梗死损伤神经功能的恢复。

Abstract:

BACKGROUND: To inhibit the expressions of prothrombin activator inhibitor 1 and tissue plasminogen activator is one potential target for the treatment of cerebral infarction.
OBJECTIVE: To investigate the expressions of serum inflammatory cytokines in rats with cerebral infarction undergoing bone marrow mesenchymal stem cell transplantation combined with edaravone.
METHODS: Sixty Sprague-Dawley rats were enrolled to prepare models of focal cerebral infarction by middle cerebral artery occlusion, and were randomly divided into four groups. Rats were given intravenous injection of PBS via tail veins for 5 consecutive days as model group, rats were subjected to intravenous injection of 2.0×109 /L bone marrow mesenchymal stem cell suspension (1 mL) via tail veins, twice daily for 5 days as stem cell transplantation group, and those were given intravenous injection of 30 mg edaravone combined with intravenous injection of 2.0×109/L bone marrow mesenchymal stem cell suspension (1 mL) via tail veins for 5 days, twice daily, as combined group.
RESULTS AND CONCLUSION: Compared with the model group, modified neurologic severity scores were lower, expressions of serum prothrombin activator inhibitor 1 and tumor necrosis factor-α mRNA in the brain decreased, and the infarct area reduced in the stem cell transplantation and combined groups. And the changed levels of above indicators in the combined group were significantly larger than those of the stem cell transplantation group. In conclusion, combination of bone marrow mesenchymal stem cell transplantation with edaravone can promote neural function recovery after cerebral infarction.
