摘要 目的观察组蛋白去乙酰化酶抑制剂(HDACIs)对重度失血性休克大鼠生存时间的影响。方法选择SD大鼠63只,采用股动静脉导管分时放血(60%)法,成功建立重度失血性休克模型48只,按照随机原则分三组:即软木酰苯胺氧肟酸(SAHA)组、丙戊酸(VPA)组和对照组。SAHA组采用SAHA 8 mg/kg静脉泵入,VPA组VPA30 mg/kg皮下注射,对照组用等量生理盐水静脉推注治疗。三组均采用BL-420F系统收集大鼠肢体导联心电图,分析各组的生存时间及12 h内生存率。结果本实验重度失血性休克大鼠建模成功率为76.19%(48/63)。对照组生存时间(7.04±0.97)h、12 h内生存率0,SAHA组分别为(11.86±2.35)、31.25%,VPA组分别为(10.56±1.56)h、12.50%。SAHA组、VPA组生存时间、12 h内生存率均高于对照组(P均<0.05),且SAHA组生存时间、12h内生存率高于VPA组(P均<0.05)。结论 HDACIs能明显延长重度失血性休克大鼠的生存时间,而且SAHA对失血性休克大鼠的生存保护作用优于VPA。
