摘  要:目的:探讨阿尔茨海默病(AD)患者血浆中3-硝基络氨酸(3-NT)和氧化低密度脂蛋白(ox-LDL)水平的变化及临床意义。方法:收集AD患者(AD组)48例,健康受试者(对照组)37例。全部研究对象均进行简明精神状态量表(MMSE)、日常生活能力量表(ADL)、Hachinski缺血指数(HIS)检测,AD患者用全面衰退量表(GDS)分级。分别用酶联免疫吸附试验(ELSIA)测定2组血浆3-NT、ox-LDL的浓度。结果:①血浆3-NT水平:AD组为(119.46±21.82)nmol.L-1,显著高于对照组(55.09±9.63)nmol.L-1(P<0.05)。Spearman相关分析显示,血浆3-NT水平与AD患者的MMSE评分呈负相关。②血浆ox-LDL水平:AD组为(112.25±17.81)μg.L-1,较对照组(47.46±10.04)μg.L-1明显升高(P<0.05)。Spearman相关分析显示血浆ox-LDL水平与AD的严重程度呈正相关。③AD组内2个指标血浆水平的Pearson相关分析显示,AD组血浆3-NT水平与血浆ox-LDL水平无明显相关性。结论:AD患者血浆3-NT、ox-LDL水平显著升高,可能与AD患者的病情严重程度密切相关,血浆3-NT、ox-LDL的测定有可能作为诊断AD的手段之一。Aim: To clarify the role of 3-nitrotyrosine(3-NT) and oxidized low density lipoprotein(ox-LDL) in the pathogenesis of Alzheimer' s disease(AD). Methods: 48 patients with Alzheimer' s disease(AD group) and 37 normal controls (control group) were recruited. Mini Mental State Examination (MMSE), Activity of Daily Living Scale(ADL) and Hachinski Ischemic Score(HIS) were performed in all patients and controls. The severity of AD was evaluated according to Global Deterioration Scale(GDS). The plasma levels of ox-LDL and 3-NT were measured in all the objects. Results: (~) The plasma level of 3-NT in the patients with AD group (119.46 ± 21.82)nmol'L-1 was significantly higher than that in the control group (55.09± 9.63)nmol'L(P〈0.05). (1) The plasma level of ox-LDL in the patients with AD (112.25 ± 17.81)Bg.L-1 was significantly higher than that in the control group (47.46 ±10.04)μg·L-1(P〈O.05). (2) Through rank correlation analysis, the severity of AD was positive correlation with the plasma concentration of ox-LDL and 3-NT. Conclusion: 3-NT and ox-LDL are involved in the pathogenesis of AD, and their alteration in level may be associated with the severity of AD.
