化浊解毒活血通络方对脑缺血再灌注损伤小鼠血清IL-6和TNF-α水平的影响

Effects of Huazhuo-Jiedu-Huoxue-Tongluo recipe on the level of IL-6 and TNF-α in mice with cerebral ischemia reperfusion injury

目的观察化浊解毒活血通络方对小鼠脑缺血再灌注损伤的局部炎症反应的影响。方法将50只昆明小鼠按随机数字表法分为脑缺血再灌注损伤模型组、中药高剂量组、中药低剂量组、尼莫地平组、假手术组，每组各10只，前四组采用线栓法制备小鼠右侧大脑中动脉脑缺血再灌注损伤模型。手术造模成功后脑缺血再灌注损伤模型组、假手术组灌服生理盐水，尼莫地平组灌服尼莫地平液（19．6g／kg·d^-1），中药高剂量组、中药低剂量组分别给予高（19．6g／kg·d^-1）、低剂量（9．8g／kg·d^-1）的化浊解毒活血通络方中药灌服。药物干预后用放免法检测各组小鼠血清IL-6、TNF-α的表达水平。结果与模型组[（219．29±39．28）pg／ml、（1．325±0．236）ng／m1]比较，中药高剂量组、中药低剂量组、尼莫地平组小鼠血清中IL-6[分别为（120．69±49．23）pg／ml、（173．97±49．03）pg／ml、（170．88±47．06）pg／m1]和TNF-α[分别为（1．086±0．178）ng／ml、（0．937±0．105）ng／ml、（1．092±0．184）ng／ml]的表达水平均明显降低（P均〈0．05）。中药高剂量组与假手术组比较，差异无统计学意义（P〉0．05）。结论化浊解毒活血通络方可抑制小鼠脑缺血再灌注损伤时炎症细胞因子的表达，减少白细胞的浸润。

Objective To observe the effect of Huazhuo-Jiedu-Huoxue Tongluo recipe on local inflammation of cerebral ischemia reperfusion injury in mice. Method Fifty Kunming Mice were randomly divided into five groups： model group, high-dose group of TCM, low-dose group of TCM, nimodiping group and sham operation group. Each group had 10 mice. Mice models of the fight middle cerebral artery CIRI in the first four groups were established through thread embolism method. Physiological saline was given to the mice in the model group and sham operation group. Nimodipine solution was given to the mice in the Nimodipine group. High and low dose of Huazhuo-Jiedu-Huoxue-Tongluo Chinese medicine decoction were given to the mice in the high dose of TCM group and low dose of TCM group respectively after the models were successfully established. To assess the expression level of IL-6 and TNF-α by radioimmunoassay after the treatment. Results Compared with model group [ （219.29± 39.28J pg/ml, （1.325 ±0.236）ng/ml] , the level of IL-6 and TNF-α of high dose of TCM group[ （120.69±49.23）pg/ml, （1.086±0.178）ng/ml], low dose of TCM group[（173.97± 49.03）pg/ml, （0.937± 0.105） ng/ml] and nimodipine group[ （170.88 ± 47.06）pg/ml, （1.092 ± 0.184） ng/ml] decrease （P〈0.05）. There is no significant difference between the high dose of TCM group and the sham operation group （P〉0.05）. Conclusion Huazhuo-Jiedu-Huoxue-Tongluo recipe can restrain the expression of inflammatory cytokines and reduce the infiltrating of leukocytes in mice with cerebral ischemia reperfusion injury.
