| 摘 要： | 目的调查原因不明的神经精神异常及甲基丙二酸尿症患儿中同型半胱氨酸血症的发生情况,探讨荧光偏振免疫测定法进行血浆或血清总同型半胱氨酸测定的应用价值。方法对2000年1月至2007年12月因原因不明的智力低下、运动障碍、癫疒间、头痛等多种神经系统异常患儿799例,甲基丙二酸尿症126例患儿,采用荧光偏振免疫测定法检测血液总同型半胱氨酸,气相色谱质谱联用分析测定尿液有机酸,液相串联质谱法进行血液氨基酸、酯酰肉碱谱分析。结果925例高危患儿中共发现同型半胱氨酸血症128例（13.84%）。799例原因不明的神经系统疾病患儿中同型半胱氨酸血症27例（3.38%）,血液丙酰肉碱及游离氨基酸浓度正常。126例甲基丙二酸尿症患儿中合并同型半胱氨酸血症101例（80.16%）,血液丙酰肉碱浓度增高。结论甲基丙二酸尿症合并同型半胱氨酸血症是甲基丙二酸尿症的主要临床表型,为鉴别诊断、正确治疗,应及早进行血液总同型半胱氨酸测定。应用荧光偏振免疫测定法检测血清/血浆总同型半胱氨酸,是同型半胱氨酸血症高危筛查的可靠方法。 |

| Abstract: | Objectives To investigate the prevalence of homocysteinemia in patients with neurological defects of unknown origin and patients with methylmalonic aciduria, and explore the application of fluorescence polarization im- munoassay in screening patients with high risk of homocysteinemia. Methods Nine hundred and twenty-five patients (586 male and 339 female, aged from 3 days to 18 years) of 29 provinces of mainland China were studied from Jan 2000 to Dec 2007. Among them, 799 were with mental retardation, move... |
| Keywords: | mental retardation homocysteinemia methylmalonic aciduria combined with homocysteinemia propionyl-carnitine |
