    摘要:

    目的:通过对一起因蜂蜜引起的钩吻碱(Gelsemine)中毒事件快速检测分析,回顾事件处置过程,为类似事件处理带来启示。方法:称取或吸取适量样本,加入硼砂-NaOH缓冲液(pH=9.6)摇匀后经乙酸乙酯提取,取有机层供气相色谱质谱联用仪(gas chromatography-mass spectrometry,GC-MS)检测分析。结果:蜂巢中钩吻碱含量为28.6 mg/kg,工具1和工具2中钩吻碱含量分别为5.85 μg、5.04 μg,蜂蜜水中钩吻碱含量为44.0mg/L,仅患者1-3血液样本中检出钩吻碱含量为22.3 μg/L-402 μg/L,尿液均检出钩吻碱含量为20.6 μg/L-299 μg/L,患者2-6尿液钩吻碱含量高于血液。结论:本次食物中毒系蜂蜜含有钩吻碱,中毒剂量低,工具可以检出钩吻碱;肾脏是钩吻碱代谢途径之一,食用2小时45分后大部分患者尿液钩吻碱含量高于血液,应重视尿液样本采集。

    Abstract:

    Objective:Through the rapid detection and analysis of a case of gelsemine?? poisoning caused by honey, and the incident disposal process was reviewed to bring inspiration for similar incident handling. Methods: The appropriate amount of samples were weighed or aspirated, adding borax-NaOH buffer solution(pH=9.6), shake well, extracted with ethyl acetate, and the organic layer was used for gas chromatography-mass spectrometry detection and analysis. Results: The gelsemine content in the honeycomb was 28.6mg/kg, and the gelsemine contents in tool 1 and tool 2 were 5.85μg and 5.04μg. The gelsemine content in honey water was 44.0mg/L, and only the blood samples of patients 1-3 detected gelsemine content of 22.3μg/L-402μg/L. The urine of all patients were detected gelsemine content of 20.6μg/L-299μg/L, and the urine gelsemine content of patient 2-6 was higher than that of blood. Conclusion: This food poisoning was caused by honey containing gelsemine, with low poisoning dosage and which can be detected from tools.The kidney is one of the metabolic pathways of gelsemine. After 2 hours and 45 minutes of consumption, most patients had higher urine gelsemine content than blood, indicating that urine sample collection should be emphasized.
