突发性聋患者血清AT-Ⅲ、PAI-1的检测及其临床意义

Changes of AT-Ⅲ and PAI-1 in the Blood of Patients With Sudden Sensorineural Hearing Loss

目的探讨抗凝血酶Ⅲ(AT-Ⅲ)和纤溶酶原激活剂抑制物-1(PAI-1)活性水平变化与突发性聋发病的关系。方法应用发色底物法测定不同病程的突发性聋患者44例和30例健康者血清AT-Ⅲ和PAI-1活性水平,并进行统计学比较。结果AT-Ⅲ、PAI-1活性水平的改变与突发性聋病程有关。发病3天内与发病一周以上患者比较,前者的血清AT-Ⅲ水平低于后者、而血清PAI-1活性水平高于后者,两者有显著差异(P<0.05);病程一周以上患者与对照组相比血清AT-Ⅲ、PAT-1活性水平无显著性差异。结论突发性聋患者三天内血清AT-Ⅲ、PAI-1活性水平的改变提示血凝与纤溶障碍与其发病有关。

Objective To study the changes of AT-III and PAI-1 in the blood of patients with sudden sensorineural hearing loss(SSHL) and investigate the relationship between their levels and the disease.Methods The levels of AT-III and PAI-1 in the blood of 44 patients with SSHL and 30 healthy volunteers were detected using chromogentic substrate method.Results The changes of AT-III and PAI-1 in the blood of patients with SSHL were correlated with the process of the disease.There was significant difference between the levels of AT-III and PAI-1 in the blood of patients within 3 days and that of patients beyond 1 week(P<0.05),and there was no significant difference between the latter and control group. Conclusion The level of AT-III and PAI-1 in the blood of patients with SSHL within 3 days changes,which suggests that the dysfunction of blood coagulation and fiber dissolution corretate with the SSHL.
