摘　　要：目的探讨脑小血管病(CSVD)患者病程进展与血管内皮功能障碍(ED)因子[同型半胱氨酸(Hcy)、肿瘤坏死因子α(TNF-α)、白细胞介素6(IL-6)和C反应蛋白(CRP)]表达水平的相关性.方法选取2016年6月至2017年9月在我科诊断为CSVD的患者60例作为研究对象,所有患者均进行了头颅MRI检查.采集外周血,利用ELISA检测与血管内皮功能障碍相关因子Hcy、TNF-α、IL-6和CRP的表达水平.对所纳入患者进行1年时间的随访,随访期内均进行头颅MRI检查.根据随访观察结果,将所纳入患者分为进展组和无进展组,比较两组患者血清Hcy、TNF-α、IL-6和CRP表达水平的差异,并分析它们与CSVD进展的相关性.结果在60例患者中,病程进展的有38例,病程无进展的有22例.与病程无进展组相比,病程进展组患者血清Hcy(17.62+7.23 VS 11.35±5.41,P=0.007)和IL-6(17.46±6.97 VS8.48士4.67,P=0.001)的表达水平高;TNF-α和CRP的表达水平在两组间无差异.经Spearman等级相关分析发现,CSVD患者的病程进展与血清Hcy(r=0.587,P=0.015)和IL-6(r=0.644,P=0.009)的表达水平存在相关性;而与TNF-α和CRP的表达水平不存在相关性.结论CSVD患者血清中血管内皮功能障碍因子Hcy、IL-6的表达水平与病程进展存在相关性,检测这些因子的表达对于判断病情预后具有一定参考意义.Objective To investigate the correlation between disease progression and expression levels of endothelial dysfunction(ED)-related factors(homocysteine[Hcy],tumor necrosis factor-alpha[TNF-α],interleukin-6[IL-6],and C-reactive protein[CRP])in patients with cerebral small vessel disease(CSVD).Methods A total of 60 patients who were diagnosed with CSVD in our department from June 2016 to September 2017 were enrolled as study subjects.All the patients underwent a cerebral MRI examination.The peripheral blood samples of the patients were collected and tested for expression levels of ED-related factors(Hcy,TNF-α,IL-6,and CRP)using ELISA.All the patients enrolled were followed up for 1 year,during which cerebral MRI examinations were regularly performed.According to the follow-up results,the patients were divided into progression group and progression-free group.The two groups were compared for differences in the expression levels of serum Hcy,TNF-α,IL-6,and CRP.Meanwhile,the correlation between these indices and CSVD progression was analyzed.Results Among the 60 patients,38 had disease progression,and 22 had no disease progression.Compared with the progression-free group,the progression group had significantly higher levels of Hcy(11.35±5.41 vs 17.62±7.23,P=0.007)and IL-6(8.48±4.67 vs 17.46±6.97,P=0.001),but there were no significant differences in the expression levels of TNF-αand CRP between the two groups.A Spearman rank correlation analysis revealed that disease progression was correlated with the expression levels of Hcy(r=0.587,P=0.015)and IL-6(r=0.644,P=0.009)but not correlated with the expression levels of TNF-αand CRP in patients with CSVD.Conclusions The expression levels of ED-related factors in serum such as Hcy and IL-6 are correlated with disease progression in patients with CSVD.Therefore,measuring the expression of these factors can provide a reference for the prognosis of the disease.
