缺氧缺血性脑病是新生儿常见的疾病之一该病死亡率高易造成新生儿脑性瘫痪智力低下等后遗症．K+通道开放剂PCOs是一类特异性增强细胞膜对K+通透性的化合物常用于治疗缺氧缺血性脑病．为探讨PCOs对缺氧缺血性脑损伤的保护作用及其机制科研人员进行了以下研究 取若干只新生小鼠均分为四组分别为①正常对照组②假手术组分离左颈总动脉后不做处理直接缝合创口③缺氧缺血性脑损伤组HIBD分离并结扎左颈总动脉后缝合创口④HIBD+PCOs组．一段时间后检测结果如下 回答下列问题 1对②组小鼠进行假手术的目的是③④组小鼠应该在正常/低氧环境下培养． 2研究发现③组小鼠脑细胞消耗的ATP主要依赖于过程产生同时还造成了在脑细胞中积累对细胞形成伤害． 3谷氨酸是神经系统中的兴奋性神经递质过量的谷氨酸会过度激活钙离子通道致使Ca2+和Na+大量内流进而造成神经细胞的凋亡．③组结果与①组比较说明缺血缺氧会造成脑部细胞病变率上升．由实验结果判断K+通道开放剂能缺血缺氧诱导的细胞凋亡． 4在研究神经细胞凋亡机制时发现B基因编码的B蛋白可以与X蛋白竞争从C﹣X蛋白复合体上夺取C蛋白释放游离的X蛋白引起细胞凋亡．有人推测PCOs是通过促进/抑制B基因的表达达到治疗缺氧缺血性脑病的效果．为了验证上述推测研究人员选择缺血缺氧条件下的神经元细胞以B﹣C蛋白复合体水平和游离X蛋白水平为检测指标进行实验请预测实验结果用坐标曲线图表示并注明PCOs添加时间．
