摘要
目的探讨转化生长因子-β1(transforming growth factorβ1,TGF-β1)在成人分泌性中耳炎(secretory otitis media,SOM)发生发展过程中的作用机制。方法采用双抗体夹心酶联免疫吸附试验法检测36例(45耳)SOM患者中耳积液、外周血浆及30例正常人外周血浆中TGF-β1的表达水平。结果TGF-β1在中耳积液、SOM患者血浆及正常人血浆中的阳性检出率均为100%;慢性SOM患者中耳积液及外周血浆中TGF-β1含量均显著高于急性SOM患者(P<0.01,P<0.01);急性SOM患者中耳积液中TGF-β1含量与同组患者血浆中含量差异无统计学意义(P>0.05),而后者与正常人血浆中含量差异无统计学意义(P>0.05);慢性SOM患者中耳积液中TGF-β1含量与同组患者血浆中含量差异无统计学意义(P>0.05),但后者显著高于正常人血浆中含量(P<0.01);接受2次及以上鼓膜穿刺和/或置管的SOM患者中耳积液及血浆中TGF-β1的含量均高于首次鼓膜穿刺和/或置管的SOM患者(P<0.01,P<0.05);TGF-β1的含量在黏液性和浆液性中耳积液组间差异无统计学意义(P>0.05)。结论TGF-β1作为重要的免疫介质,参与成人SOM的发生发展,尤其在SOM的慢性病程中发挥重要作用。
