摘 要:目的 探讨异丙酚和七氟醚对阿霉素化疗诱发大鼠心肌损伤的影响.方法 健康雄性Wistar大鼠24只,3月龄,体重212~270 g,采用随机数字表法,分为4组(n=6),对照组(C组)腹腔注射等容量的生理盐水;阿霉素组(ADM组)腹腔注射阿霉素2.5 mg/kg,隔日1次,共6次(共11d);阿霉素-异丙酚组(ADM-Pro组)阿霉素给药方法同ADM组,最后一次给药后3d,实施异丙酚麻醉:腹腔注射异丙酚总量200 mg/kg,首次100 mg/kg,1h后追加剩余量,麻醉时间约2h;阿霉素-七氟醚组(ADM-Sevo组)阿霉素给药方法同ADM组,最后一次给药后3d,实施七氟醚麻醉:吸入1.5% ~3.0%七氟醚,维持2h.麻醉结束后,取血标本,采用免疫发光技术测定血清cTnI浓度.取心肌组织,采用免疫组化法测定心肌组织caspase-3的表达.结果 与C组比较,ADM组、ADM-Pro组和ADM-Sevo组血清cTnI浓度升高,心肌组织caspase-3表达上调(P<0.05);与ADM组比较,ADM-Pro组和ADM-Sevo组血清cTnI浓度降低,心肌组织caspase-3表达下调(P<0.05);ADM-Pro组和ADM-Sevo组上述指标比较差异无统计学意义(P>0.05).结论 异丙酚和七氟醚麻醉均可减轻阿霉素化疗诱发的大鼠心肌损伤,效果无明显差异.Objective To investigate the effects of propofol and sevoflurane on adriamycin chemotherapy-induced myocardial damage in rats.Methods Twenty-four healthy male Wistar rats, aged 3 months, weighing 212-270 g, were randomly divided into 4 groups (n =6 each) using a random number table: control group (group C) , adriamycin group (group ADM) , adriamycin-propofol group (group ADM-Pro) , and adriamycin-sevoflurane group (group ADM-Sevo).The equal volume of normal saline was injected intraperitoneally in group C.In group ADM, adriamycin 2.5 mg/kg was injected intraperitoneally once every other day for 6 times (11 days in total).In group ADM-Pro, adriamycin 2.5 mg/kg was injected intraperitoneally once every other day for 6 times, and at 3 days after the last administration of adriamycin, propofol anesthesia was performed as follows : the total amount of propofol injected intraperitoneally was 200 mg/kg, the initial dose was 100 mg/kg, and 1 h later the remaining amount was added, and the duration of anesthesia was about 2 h.In group ADM-Sevo, adriamycin 2.5 mg/kg was injected intraperitoneally once every other day for 6 times, and at 3 days after the last administration of adriamycin, sevoflurane anesthesia was performed as follows: 1.5%-3.0% sevoflurane was inhaled for 2 h.After the end of anesthesia, blood samples were collected for determination of serum cardiac troponin (cTnI) concentrations.Myocardial specimens were collected for detection of caspase-3 expression by immuno-histochemistry.Results Compared with group C, the serum cTnI concentration was significantly increased, and the caspase-3 expression was up-regulated in ADM, ADM-Pro and ADM-Sevo groups (P〈 0.05).Compared with group ADM, the serum cTnI concentration was significantly decreased, and the caspase-3 expression was down-regulated in ADM-Pro and ADM-Sevo groups (P〈0.05).There was no significant difference in the parameters mentioned above between group ADM-Pro and group ADM-Sevo (P〉0.05).Conclusion Pr
