白血病人血清的^(31)PNMR研究

THE STUDY OF LEUKAEMIA SERUM BY ^(31)P NMR

运用31 P核磁共振波谱 (NMRS)研究血清中磷脂的代谢变化 ,并探讨该法对白血病诊断的可行性 .方法采用MSL 30 0MHz型超导核磁共振仪测量白血病人及健康人血清标本 ,通过分析比较血清中磷脂酰胆碱 (PC)信号及磷脂酰乙醇胺和 (神经 )鞘磷脂 (PE +SM)信号相对积分面积 ,了解各自血清中的磷脂含量水平 .结果 ,白血病人血清中的磷脂信号强度相对正常人明显偏低 ,反映了对应的PC及 (PE +SM)含量相对正常人偏低 ,尤其对初发未治疗的病人 ,差别更加明显 .结论 ,本法可作为研究血清中磷脂的变化、代谢情况及白血病人临床诊断的新方法 .

To investigate the feasibility of serum \{\}\+\{31\}P NMRS in the study phospholipid metabolites and diagnosis of leukaemia. Method: Serum sample of leukaemia patients and healthy controls were collected and measured by \{\}\+\{31\}P NMRS with MSL 300MHz spectrometer. The phospholipid contents were known by contraxt relatively integral area of PC signal and (PE+SM) signal. Results: In spectra of serum of leukaemia patients, the phospholipid signal intensities were significantly decreases. It reflected lower phosphatidylcholine and phosphatidylcholine and sphingomyelin content in serum of leukemia patients, especially for original untreatment patient. Conclusions: These results suggest that serum \{\}\+\{31\}P NMRS may likely become a promising new method for the study of phospholipid changes or metabolites and identifying the presence of leukaemia. \;
