摘要 目的观察促红细胞生成素(EPO)对癫痫大鼠心肌中JNKMAPK和P38MAPK表达的影响。方法将雄性Wistar大鼠随机分为对照组(PBS组)、模型组(KA组)和EPO组,每组再分别按0、2、6、12、24 h的时间点分为5个小组。采用免疫组化方法检测各时间点心肌中P38MAPK和JNKMAPK的表达,用Image-Pro Plus图像分析软件测定心肌组织中P38MAPK和JNKMAPK表达的灰度值。结果心肌组织中P38MAPK和JNKMAPK的表达从癫痫发作开始逐渐增加,在发作后6 h达到高峰,以后逐渐下降,KA组与PBS组在2 h、6 h和12 h时间点比较均有统计学差异(P均<0.05),EPO组与KA组在2 h、6 h和12 h时间点比较均有统计学差异(P<0.05),而PBS组和EPO组与KA组在0 h和24 h时间点比较差异均无显著性(P>0.05)。结论应用EPO干预后,EPO通过一定的信号途径使心肌细胞中JNKMAPK和P38MAPK的表达下降,发挥对心肌的保护作用。
