目的 采用1H-NMR代谢组学方法分析复方柴归方干预抑郁模型大鼠血清代谢物组的变化规律。方法 采用慢性温和不可预知应激(CUMS)程序对大鼠进行造模,以复方柴归方及阳性药(文拉法辛)为干预药物,采用核磁共振方法对大鼠血清进行分析,数据预处理后导入SIMCA-P 14.1软件进行多元统计分析,从小分子代谢物角度对复方柴归方的抗抑郁药效进行验证,并寻找出潜在的疾病生物标志物和药物疗效标志物。结果 CUMS抑郁大鼠模型复制成功,代谢组学结果表明与模型组相比,CUMS抑郁大鼠经阳性药和复方柴归方干预后血清中异亮氨酸、氧化三甲胺和肌酸水平升高,N-乙酰糖蛋白、胆碱和葡萄糖水平降低,差异显著(P<0.05、0.01)。结论 复方柴归方干预后CUMS模型大鼠血清差异代谢物水平明显回调,该研究可为复方柴归方抗抑郁作用机制研究提供参考依据。

Objective To analyze the effect of Compound Chaigui Prescription on the changes of serum metabolites in rats with depression by 1H-NMR metabolomics.Methods Rats model established were modeled by chronic mild unpredictable stress (CUMS) procedure. Compound Chaigui Prescription and positive drugs (venlafaxine) were used as intervention drugs. Rat serum was analyzed by nuclear magnetic resonance (NMR) method. After data pretreatment, SIMCA-P 14.1 software was introduced for multivariate statistical analysis to verify the antidepressant efficacy of Compound Chaigui Prescription from the perspective of small molecule metabolites, and find potential disease biomarkers and drug efficacy markers.Results The CUMS depression rat model was successfully replicated. The metabolomics results showed that the levels of isoleucine, trimethylamine oxide, and creatine in the serum of CUMS-depressed rats were significantly higher than those of the model group. The levels of N-acetyl-glycoprotein, choline, and glucose were decreased with a significant difference (P < 0.05, 0.01).Conclusion The serum metabolite levels in CUMS model rats were significantly corrected after Compound Chaigui Prescription intervention. This study can provide reference for the study of antidepression mechanism of Compound Chaigui Prescription.
