阻塞性睡眠呼吸暂停低通气综合征患者血浆脂肪细胞型脂肪酸结合蛋白的变化及意义

目的探讨脂肪细胞型脂肪酸结合蛋白（A-FABP）与阻塞性睡眠呼吸暂停低通气综合征（OSAHS）的关系。方法 120例受试者均接受多导睡眠图监测,根据呼吸暂停低通气指数（AHI）及体重指数（BMI）将受试者分组。控制OSAHS严重程度及肥胖程度的影响,分析各组A-FABP与AHI的相关性。分析A-FABP与AHI、BMI、最低血氧饱和度、平均血氧饱和度、颈围、腰臀比、胰岛素抵抗指数（IRI）的相关性。结果排除年龄与性别的影响,在BMI相匹配的各组中,重度OSAHS者血浆A-FABP水平显著高于非OSAHS者。排除年龄与性别的影响,在AHI相匹配的非OSAHS和重度OSAHS组中,肥胖者血浆A-FABP的水平显著高于正常体重者和超重者。OSAHS患者血浆A-FABP水平与AHI、BMI、IRI、颈围、SLT90%、腰臀比呈正相关,与LSaO2和MSaO2呈负相关。非OSAHS者血浆A-FABP水平与BMI及IRI相关。结论 OSAHS患者的病情越严重,A-FABP的水平越高。不论是否患有OSAHS,血浆A-FABP的水平均与BMI、IRI呈正相关。

Clinical Significance of Serum A-FABP in Patients with Obstructive Sleep Apnea Hypopnea Syndrome

Objective To investigate the relationship between adipocyte fatty acid binding protein(A-FABP) and obstructive sleep apnea hypopnea syndrome(OSAHS).Methods A total of 120 patients were recruited and underwent polysomnography.The groups were allocated according severity of OSAHS and obesity.Plasma A-FABP(ng/mL) levels were measured by ELISA.The associations between A-FABP and AHI,BMI,LSaO2,MSaO2,neck collar,waist/hip ratio,insulin resistance index were analyzed.Results Plasma A-FAPB levels were significantly...
