目的:利用代谢组学手段检测大脑中动脉阻塞(Middle Cerebral Artery Occlusion,MCAO)模型大鼠血清中氨基酸含量,微观上阐明氨基酸注射液的疗效以及部分作用机制。方法:采用邻苯二甲醛(O-Phthalaldehyde,OPA)柱前在线衍生反相高效液相色谱法,采用荧光检测,梯度洗脱,建立了血清中氨基酸代谢谱的相对定量分析方法,测定36例大鼠血清中的15种氨基酸含量。流动相A为10 mol/L Na2HP04-Na2B07缓冲液(pH=7.95),B为乙腈-甲醇-水(45:45:15,V/V/V),线性梯度洗脱,流动相B在6 min内由5%增加至17.2%,6~35 min内由17.2%增加至52%。结果:1)该法在35 min之内分离出15种氨基酸;2)经主成分分析,3个组在空间上得到很好地分离,氨基酸代谢谱发生了一定的变化;3)利用SPSS方差分析,有6个氨基酸在分离各组有统计学意义。结论:丹红注射液通过部分调节MCAO摄动通路改善脑梗死大鼠血清部分氨基酸的代谢趋势。 |
English Summary: |
To determine the content of amino acid to clarify the curative effect and the functioning mechanism of DanHong injection on microscopic.Methods:OPA reversed phase high performance liquid chromatography (HPLC),precolumn derivatization method fluorescence detection, gradient elution were used.Mobile phase A was 15mol/L Na2HP04 - Na2B07 buffer (pH = 7.95), B was acetonitrile - methanol - water (45:45:15, V/V/V).As for linear gradient elution, mobile phase B in 6 min increased from 5% to 17.2%, increased from 17.2% to 52% in 6-35 min.Results:1) Fifteen kinds of amino acids were isolated within 35 min; 2) using principal component analysis, three groups were well separated; 3) using the SPSS analysis of variance, there were six amino acids in the separation between groups was statistically significant.Conclusion:Danhong injection can improve metabolic trend of amino acid in cerebral infarction rats serum through adjusting perturbed pathways |
