| TITLE： | Investigation on the mechanism of Compound zaoren granules in improving insomnia based on serum meta-bonomics |
| 摘要： | 目的 研究复方枣仁颗粒改善失眠的机制。方法将49只小鼠随机分为空白组、模型组、阳性对照组1（艾司唑仑片0.5mg/kg）、阳性对照组2（舒眠胶囊0.6g/kg）和复方枣仁颗粒低、中、高剂量组（2.5、5、10g/kg），每组7只。通过慢性不可预见性温和应激刺激联合对氯苯丙氨酸建立小鼠失眠模型，通过小鼠旷场实验、戊巴比妥钠协同催眠实验考察小鼠行为学变化，通过苏木精-伊红染色观察小鼠下丘脑组织病理形态学变化。结合超高效液相色谱-飞行时间质谱技术对小鼠血清进行代谢组学分析及多元统计分析筛选差异代谢物，并基于MetaboAnalyst5.0数据库进行代谢通路分析。结果与空白组比较，模型组小鼠总行进距离、中央区域进入次数、中央区域移动距离显著减少（P＜0.05），总静息时间比例显著升高（P＜0.05），睡眠时长显著缩短（P＜0.05），下丘脑神经细胞受损且空泡化严重。与模型组比较，复方枣仁颗粒低、中剂量组小鼠总行进距离显著增加（P＜0.05）、总静息时间比例显著降低（P＜0.05），复方枣仁颗粒高剂量组小鼠睡眠时长显著延长（P＜0.05）；各给药组小鼠下丘脑组织神经细胞均不同程度恢复，其中复方枣仁颗粒高剂量组小鼠下丘脑组织细胞与空白组较为接近。通过代谢组学分析共得到18个差异代谢物（如苯基丙氨酸、牛磺酸、正缬氨酸、甲硫氨酸等）及4条重要的氨基酸代谢通路（L-苯丙氨酸、酪氨酸和色氨酸生物合成，牛磺酸和次牛磺酸代谢，L-苯丙氨酸代谢，半胱氨酸和甲硫氨酸代谢）。结论复方枣仁颗粒可通过回调苯基丙氨酸、牛磺酸等差异代谢物及调节4种氨基酸代谢通路，使紊乱的体内代谢恢复正常，从而发挥改善失眠的作用。 |
| ABSTRACT： | OBJECTIVE To study the mechanism of Compound zaoren granule in improving insomnia. METHODS Forty-nine mice were divided into blank group， model group， positive control group 1 （Estazolam tablets 0.5 mg/kg），control group 2 （Shumian capsule 0.6 g/kg）， Compound zaoren granule low-dose， medium-dose and high-dose groups （2.5， 5， 10 g/kg）， with 7 mice in each group. The insomnia model was established by chronic unpredictable mild stress combined with 4-chloro-DL- phenylacetic acid. The behavioral changes of mice were investigated through open field test and pentobarbital sodium synergistic hypnosis experiment， as well as the pathomorphology of mice hypothalamus tissue was observed by HE staining. The metabonomics analysis and multivariate statistical analysis of serum in mice were performed by UHPLC-Q-TOF-MS/MS， and the differential metabolites were screened out； the metabolic pathway analysis was conducted based on MetaboAnalyst 5.0 database. RESULTS Compared with blank group， the total travelling distance， the number of entering the central region and the moving distance in the central region of the model group were significantly reduced （P＜0.05）， the proportion of total rest time was significantly increased （P＜0.05）， the sleep duration of mice was significantly shortened （P＜0.05）， and hypothalamic nerve cells damaged and severely vacuolated. Compared with model group， the total travelling distance of Compound zaoren granule low-dose and medium-dose groups were increased significantly and the proportions of total rest time of those groups were decreased significantly （P＜0.05）， and the sleep duration of mice in Compound zaoren granule high-dose group was prolonged significantly （P＜0.05）； the hypothalamic nerve cells of mice in each administration group recovered to varying degrees， and the hypothalamus histiocytes of mice in the Compound zaoren granules high-dose group were closer to those in the blank group. A total of 18 differential metabolites （such as phenylalanine， taurine， norvaline， methionine） and 4 important amino acid metabolic pathways （L-phenylalanine， tyrosine and tryptophan biosynthesis； taurine and hypotaurine metabolism； L-phenylalanine metabolism； cysteine and methionine metabolism） were identified through metabolomics analysis. CONCLUSIONS Compound zaoren granules can normalize the disordered metabolism in vivo by regulating differential metabolites such as phenylalanine， taurine， and four amino acid metabolic pathways， so as to improve insomnia. |
