摘要 选择哮喘患者63例(其中哮喘急性发作期组33例,哮喘缓解期组30例)及健康对照组22例。测定三组肺功能,对诱导痰进行炎症细胞分类计数,测定诱导痰上清液中血管内皮生长因子(VEGF)水平,并分析VEGF与嗜酸粒细胞、肺功能之间的相关性。结果哮喘急性发作期组诱导痰中嗜酸粒细胞数、VEGF水平为1.8(0.7-2.9)×10^9/L、(4.8±1.1)μg/L,哮喘缓解期组为0.8(0.3—1.3)×10^9/L、(2.1±40.6)μg/L,健康对照组为0.0(0.0—0.1)×10^9/L、(0.9±0.2)μg/L。三组诱导痰中嗜酸粒细胞数、VEGF水平比较差异有统计学意义(P均〈0.05);哮喘患者诱导痰中VEGF水平与痰中嗜酸粒细胞数呈正相关(r=0.52,P〈0.01),与FEV。占预计值百分比、FEV1/FVC呈负相关(r=-0.41、-0.56,P均〈0.01)。认为哮喘患者肺组织中VEGF表达上调可能参与了哮喘发生、发展的过程。
