摘要(Abstract)：

目的探讨非痴呆型脑小血管病(cerebral small vessel disease,CSVD)患者血清同型半胱氨酸(homocysteine,Hcy)、转化生长因子-β1(transformed growth factor-1,TGF-β1)及脑源性神经营养因子(brain-derived neurotrophic factor,BDNF)表达与认知功能障碍的关系。方法选取117例CSVD患者为研究对象,根据是否存在认知功能障碍(vascular cognitive impairment of none dementia,VCIND)分为VCIND组(41例)和CSVD组(76例)。检测2组血清Hcy、TGF-β1、BDNF水平,分析VCIND组血液指标水平与蒙特利尔认知评估(MoCA)评分的相关性。结果 VCIND组患者血清Hcy水平较CSVD组升高,血清TGF-β1、BDNF水平较CSVD组降低(P<0.05)。Logistic回归分析显示,Hcy为VCIND的危险因素(B=0.334,OR=1.396,P=0.000),而TGF-β1、BDNF为VCIND的保护因素(B=-0.066,OR=0.937,P=0.005;B=-0.751,OR=0.472,P=0.004)。血清Hcy水平与MoCA评分呈负相关,血清TGF-β1、BDNF表达与MoCA评分呈正相关性(P<0.05)。结论 Hcy、TGF-β1及BDNF表达与VCIND的发生有关,其血清水平能够反映患者认知功能障碍程度。
