Hypothermia treatment is one of the neuroprotective strategies that improve neurological outcomes effectively after brain damage. Minimally invasive surgery (MIS) has been an important treatment of intracerebral hemorrhage (ICH). Herein, we evaluated the neuroprotective effect and mechanism of MIS joint local cooling lavage (LCL) treatment on ICH via detecting the inflammatory responses, oxidative injury, and neuronal apoptosis around the hematoma cavity in rats. ICH model was established by type IV collagenase caudatum infusion. The rats were treated with MIS 6 h after injection, and then were lavaged by normothermic (37 °C) and hypothermic (33 °C) normal saline in brain separately. The results indicated that MIS joint LCL treatment showed enhanced therapeutic effects against ICH-induced inflammation injury and apoptosis in rats, as convinced by the decline of TUNEL-positive cells, followed by the decrease of IL-1β and LDH and increase of IL-10 and SOD. This study demonstrated that the strategy of using MIS joint LCL may achieve enhanced neuroprotection against ICH-induced inflammation injury and apoptosis in rats with potential clinic application.
亚低温治疗是脑损伤后有效改善神经功能结局的神经保护策略之一。微创手术(MIS)一直是脑出血(ICH)的重要治疗方法。在此,我们通过检测大鼠血肿腔周围的炎症反应、氧化损伤和神经元凋亡,评估了MIS联合局部低温灌洗(LCL)治疗ICH的神经保护作用及其机制。通过向尾状核注射IV型胶原酶建立ICH模型。注射后6小时对大鼠进行MIS治疗,然后分别用常温(37°C)和低温(33°C)生理盐水对脑部进行灌洗。结果表明,MIS联合LCL治疗对ICH诱导的大鼠炎症损伤和凋亡具有增强的治疗效果,这可通过TUNEL阳性细胞数量的减少得到证实,随后IL-1β和LDH减少,IL-10和SOD增加。本研究表明,MIS联合LCL策略可能对ICH诱导的大鼠炎症损伤和凋亡具有增强的神经保护作用,具有潜在的临床应用价值。
