“肝郁证”大鼠模型的建立及代谢组学的初步研究

目的:建立并验证肝郁证大鼠模型,在此基础上运用代谢组学的方法研究肝郁证代谢组学特征及生物标志物,探讨代谢组学用于证候研究的可行性。方法:12只Wistar大鼠随机分为模型组与对照组(每组6只)。模型组采用慢性束缚的方法造成肝郁证大鼠模型,通过行为学观察、糖水偏好实验、血浆皮质酮、胃黏膜、肾上腺病理观察评价模型。运用1HNMR技术对两组大鼠血清进行代谢组学分析。结果:模型组大鼠行为异常,主要表现为躲避、活动减少、大便松散、皮色失去光泽,造模第2周开始生长较对照组缓慢(P<0.05);糖水偏好实验显示造模过程中模型组对糖水的偏好摄入少于对照组(P<0.05);造模结束后模型组大鼠血浆皮质酮水平高于对照组(P<0.01);造模后模型组胃黏膜、肾上腺未见明显病理改变,但模型组肾上腺体重指数高于对照组(P<0.05)。代谢组学分析表明,与对照组相比,模型组血浆中葡萄糖(Glucose)和肌酸(Creatine)的含量明显偏高,而3-羟基丁酸(3-HB)、谷氨酰胺(Gln)、磷脂酰胆碱(PtdCho)、磷酸胆碱(PCho)和不饱和脂肪酸(UFA)的含量明显偏低。结论:从病因学、行为学和病理表现上慢性束缚的方法成功构建了肝...

Establishment of rat model of syndrome of stagnation of liver qi and primary study using metabonomics

Objective:To establish and validate the rat model of syndrome of stagnation of liver qi,followed by a primary study on this model with 1H NMR based on metabonomics to explore the essence of syndrome of stagnation of liver qi. Methods:Twelve Wistar male rats were randomly divided into two groups(model group and control group).The rats of model group were restrained by special equipment for 21 days to get into stagnation of liver qi.The behavior,fluid consumption test and plasma CORT of rats were recorded.At ...
