[摘要]目的建立高效液相色谱-电化学检测器(HPLC-ECD)法测定遗传性嗜铬细胞瘤家系血浆儿茶酚胺及其代谢产物的含量的方法。方法工作电极为玻璃电极,参比电极为Ag-AgCl 电极,电压0.6V,温度30℃。色谱柱:Ultimate XB-C 18(4.6mm×150mm,5μm);以甲醇为流动相A,0.1%磷酸二氢钠(含EDTA-Na 和辛烷磺酸)水溶液为流动相B,梯度洗脱,流速为0.8mL/min;柱温为室温;检测波长:280nm;进样量:20μL。结果正常健康人中肾上腺素(E)、去甲肾上腺素(NE)、甲氧基去甲肾上腺素(NMN)、甲氧基肾上腺素(MN)分别为(56.71±25.67)、(98.62±36.90)、(78.36±22.36)、(33.27±14.62)ng/L。嗜铬细胞瘤家系中确诊的2例嗜铬细胞瘤患者的NE 分别为353.36、563.87ng/L 和NMN 分别为425.71、527.65ng/L,其余18位家属的相关检测值在正常健康成人的范围内,其他2位家属的相关检测值比正常值高,建议去医院进一步检查。结论该方法简便,灵敏、准确,可用于临

床嗜铬细胞瘤患者的检测。

[Abstract]Objective To establish a method for the determination of catecholamines and their metabolites in plasma of hereditary pheochromocytoma families by high performance liquid chromatography-electrochemical detector (HPLC-ECD).Methods The working electrode was a glass electrode and the reference electrode was an Ag -AgCl electrode with a voltage of 0.6V and a temperature of 30℃.Using Ultimate XB-C 18(4.6mm ×150mm,5μm);using methanol as mobile phase A,0.1%sodium dihydrogen phosphate (containing EDTA-Na and octanesulfonic acid)aqueous solution as mobile phase B,gradient elution,flow rate 0.8mL/min;column temperature was room temperature;detection wavelength was 280nm;injection volume was 20μL.Results In normal healthy people,the contents of epinephrine(E),norepinephrine (NE),methoxy norepinephrine (NMN),methoxy-adrenalin (MN)were (56.71±25.67),(98.62±36.90),(78.36±22.36),(33.27±

14.62)ng/L.The NEs of 2patients with pheochromocytoma diagnosed in pheochromocytoma were 353.36,563.87ng/L and NMN were 425.71and 527.65ng/L,respectively.The correlation detection values of the other 18family members were within

the range of normal healthy adults.The correlation detection values of the other two family members were higher than the normal values.it is recommended to go to the hos⁃pital for further examination.Conclusion This method is simple,sensitive and accurate and can be used for the detection of patients with clinical pheochromocytoma.
