| 摘 要： | 目的 探讨血浆3-硝基酪氨酸(3-NT)浓度与阿尔茨海默病(AD)患者认知功能损害的关系.方法 应用简易精神状态检查量表(MMSE)检测入组患者的认知功能,将其分为3组,即正常对照组(NC,37例)、血管性痴呆组(VD组,41例)、AD组(48例),分别用酶联免疫吸附试验(ELSIA)测定3组患者的血浆3-NT浓度,并对AD组患者的血浆3-NT浓度与MMSE得分及各个认知领域分值进行相关性分析.结果 NC组、VD组、AD组患者血浆3-NT浓度分别为(55.09±9.63) nmol/1、(70.42±11.45) nmol/1、(119.46±21.82) nmol/1,AD组患者血浆3-NT浓度明显高于NC组、VD组(均P＜0.05)；AD组患者血浆3-NT浓度与MMSE得分成明显负相关(r=-0.638,P＜0.05)；AD组患者血浆3-NT浓度与记忆力、定向力、注意力和计算能力均成明显负相关(均P＜0.05).结论 血浆3-NT浓度测定有可能作为判断AD患者认知功能损害的生化指标,亦可作为AD与VD鉴别诊断的生物学指标.

| Abstract: | Objective To explore the relationship between plasm 3-nitrotyrosine （3-NT） levels and Alzheimer disease （AD）. Methods The subjects were 48 patients with AD and 78 controls ,including 41 patients with vascular dementia （VD） and the 37 normal controls （NC）. Cognitive function and plasm 3-NT levels in three groups were tested by Mini mental state examination （MMSE） and enzyme linked immunosorbent assay （ ELISA）, respectively. Results The levels of plasm 3-NT were （ 119.46 ± 21.82 ） nmol/LinAD patients, （70. 42 ± 11.45） nmol/L in VD, and （55. 09 ±9. 63） nmol/L in NC, respectively （ all P 〈 0.05 ）. The correlation analysis revealed that the plasm 3-NT levels were negatively correlated with the total MMSE scores （r = -0. 638 ,P 〈 0.05）. Multivariable linear regression showed that the plasm 3-NT levels were also negatively correlated with the memory scores,the orientation scores , the attention scores and the calculation in the AD groups （ all P 〈 0.05 ）. Conclusion 3-NT may be used as the biochemical indicator for observing AD, and may be used for differentiating AD and VD. |
