【摘要】Objective To study the relationship between the plasma level of asymmetric dimethylarginine (ADMA) and the damage degree of white matter and the changes of cognitive function in patients with cerebral small vessel disease.Methods 120 patients with white matter lesions,induced by cerebral small vessel disease,were randomly selected.All patients were divided into group with or without cognitive dysfunction according to the results of MoCA scale.The plasma level of ADMA was detected with high-perfomance liquid chromatography method.Scheltens semi-quantitative evaluation was used to detect the damage degree of white matter.Correlation analysis was used to evaluate the relationship between the plasma level of ADMA and white matter lesions and cognitive dysfunction.Results There were 42 patients with cognitive dysfunction and 78 patients without cognitive dysfunction.The plasma level of ADMA in patients with cognitive dysfunction ( ( 1.57 ±0.56) μg/ml) was significantly higher than patients without cognitive dysfunction ( (0.89 ±0.23 ) μg/ml) (P ＜ 0.01 ).Scheltens semi-quantitative evaluationfor patients with cognitive dysfunction and patients without cognitive dysfunction was 8.01 ±
2.50and 2.49 ± 0.59,respectively.There was significant difference between this two groups (P ＜ 0.01 ).The plasma level of ADMA positively correlated with the damage degree of white matter lesions and the changes of cognitive function.The correlation coefficients were 0.913 and 0.837,respectively ( All P ＜ 0.01 ).Conclusion ADMA may be involved in the process of white matter damage caused by cerebral small vessel disease.The detection for plasma levels of ADMA may contribute to the prevention and early diagnosis of patients with cognitive dysfunction caused by cerebral small vessel disease.%目的 研究血浆不对称二甲基精氨酸水平与脑小血管病患者脑白质损伤程度及认知功能水平之间的关系.方法 随机选取小血管病变所致脑白质损伤患者120例,根据蒙特利尔认知评价(Montred cognitive assessment,MoCA)量表将患者分为认知功能障碍组及非认知功能障碍组；采用高效液相色谱法测定所有患者血浆中不对称二甲基精氨酸水平,并通过Scheltens半定量评定表评价脑白质损伤程度.比较2组患者血浆不对称二甲基精氨酸水平及脑白质损伤程度之间的差异,并通过相关分析评价血浆不对称二甲基精氨酸水平与脑白质损伤程度及认知功能障碍之间的关系.结果 认知功能障碍组患者42例,非认知功能障碍组患者78例；认知功能障碍组患者血浆不对称二甲基精氨酸水平[(1.57±0.56) μg/ml]及脑白质损伤程度评分[(8.01±2.50)分]均明显高于非认知功能障碍组患者[(0.89±0.23) μg/ml,(2.49±0.59)分],差异均有统计学意义(P＜0.01).相关分析结果表明认知功能障碍组患者血浆不对称二甲基精氨酸水平与脑白质损伤程度及认知功能水平均呈正相关,相关系数分别为0.913与0.837(均P＜0.01).结论 不对称二甲基
精氨酸可能参与了小血管病变患者脑白质的损伤过程,通过检测血浆不对称二甲基精氨酸水平可能有助于脑小血管病相关认知功能障碍的预防与早期诊断. 【总页数】3页(530-532)
