OSAHS患者CPAP治疗前后MMP-9和FFA水平变化

目的探讨OSAHS治疗前后MMP-9、FFA的变化及呼吸紊乱指数、最低血氧饱和度及血脂的相关性,为研究OSAHS病情程度及与心血管疾病、内分泌疾病的关联提供相关依据。方法对50例符合纳入条件的重度OSAHS患者在进行CPAP治疗前及治疗后6个月PSG监测并抽取清晨空腹血清测定MMP-9、FFA及临床常规血脂四项(TG、TCH、HDL、LDL),并做相关比较。结果①OSAHS患者治疗后呼吸紊乱指数(AHI)下降,与术前比较有统计学意义(P<0.01),最低血氧饱和度(SO2)上升,与术前比较有统计学意义(P<0.05)。②OSAHS患者治疗后MMP-9水平较治疗前有统计学意义(P<0.01)。FFA水平较治疗前有统计学意义(P<0.01)。③OSAHS患者治疗后TG、TCH、LDL值下降,HDL值上升,较术前均有统计学意义(P<0.01)。结论应用持续正压通气(continuous positive airway pressure,CPAP)治疗OSAHS可以降低MMP-9与FFA的水平,有效降低OSAHS所致炎症反应及心血管疾病的发生。

Changes of MMP-9 and FFA levels in OSAHS patients before and after CPAP treatment

Objective To study the relativity between the serum levels of matrix metalloproteinase(MMP-9),FFA and apnea-hypopnea index(AHI),minimum oxygen saturation(SO2),blood lipids in OSAHS patients before and after continuous positwe airawy pressure(CPAP) treatment to present evidences for assessment of OSAHS and its relativity with cardiovascular and endocrine diseases.Methods Before CPAP treatment,PSG was monitored and the serum levels of MMP-9,FFA and four lipids(TG,TCH,HDL,LDL) were determined in 50 patients wi...
