目的 研究四逆散对创伤后应激障碍(PTSD)所致睡眠障碍大鼠的睡眠潜伏期影响.方法 用随机数表法将SD大鼠分为5组,每组10只:假手术组、模型组、阴性对照组、阳性对照组和实验组.用幽闭电击法制备PTSD模型,假手术组不复制模型.模型组不给药,阴性对照组灌胃等体积0.9％ NaCl,阳性对照组灌胃盐酸帕罗西汀溶液0.42 mg· mL-1,实验组灌胃四逆散水煎液(含生药0.24g·mL-1)10 mL·kg-.于应激造模前1h给药,每天灌服1次,共计7d.第7天干预结束后,检测非快眼动睡眠期(NREMS)和快眼动睡眠期(REMS).结果 假手术组与模型组的REMS和NREMS分别为(8.66±3.04),(23.27±10.15)min;(65.90±25.08),(109.36±43.43)min,组间比较差异均有统计学意义(均P＜0.01),提示造模后大鼠出现入睡困难现象.阳性对照组与实验组的REMS和NREMS分别为(8.17±2.29),(6.83±2.84) min;(162.29±46.19),(195.24±67.96) min,2个给药组与模型组比较,差异均有统计学意义(P ＜0.05,P＜0.01),提示盐酸帕罗西汀和四逆散干预均能明显促进大鼠入睡.结论 中药复方四逆散可以明显促进PTSD所致睡眠障碍大鼠快速入睡.“,”Objective To study the effects of sleep latency to the intervention of Sinisan in rats with post-traumatic stress and sleep disorder (PTSD).Methods Fifty SD rats were divided equally into 5 groups:sham operation group,model group,negative control group group,positive control group and experimental group.PTSD model was made by claustrophobia,but not in sham operation group.The model group was not given the drug,the negative control group was given equal volume 0.9％ NaC1,and the positive control group was given paroxetine hydrochloride 0.42 mg · mL-1.The experimental group was perfused with the decoction of Sinisan (containing 0.24 g · mL-1) 10 mL · kg-1.The drug was administered 1 h before the stress model was administered once a day for a total of 7 d.After intervention on the 7th day,nonrapid eye movements sleep (NREMS) and eye movements sleep (REMS) were detected.Results The REMS and NREMS of sham operation group and model group were respectively (8.66 ± 3.04),(23.27 t 10.15) min;(65.90 ± 25.08),(109.36 ± 43.43) min,the differences between groups were statistically significant(all P ＜ 0.01);the result suggest that difficulty in falling asleep appears in rats after modeling.The REMS and NREMS of the positive control group and the experimental group were respectively (8.17 ±2.29),(6.83 ±2.84) min;(162.29 ±46.19),(195.24 ±67.96) min.Comparison between the drugs groups and model group,the difference was statistically significant (P ＜0.05,P ＜0.01).These Results suggested that both paroxetine hydrochloride and Sinisan can significantly promote the sleep of rats.Conclusion Traditional Chinese medicine compound Sinisan can obviously promote the rats with sleep disorder caused by PTSD.
