摘要
目的:临床探讨阻塞性睡眠呼吸暂停低通气综合征(OSAHS)导致阴茎勃起功能障碍(ED)与外周血一氧化氮(NO)和一氧化氮合酶(NOS)水平的相关性。方法:经多导睡眠监测仪(PSG)及阴茎夜间勃起功能测定(NPT),诊断OSAHS合并ED患者60名作为ED组,同时随机选择30名健康志愿者设立为健康组,分析ED组和健康组血清NO和NOS水平,及轻、中、重ED组血清NO、NOS水平、阴茎血容积变化率及IIEF-5总分差异,并将轻、中、重ED组阴茎血容积变化率及IIEF-5总分分别与各自血清NO和NOS水平进行相关性分析。结果:ED组的外周血NO和NOS水平均低于无ED组和健康组,差异具有统计学意义(P<0.05)。阴茎血容积变化率与NO(r=0.356,P<0.05)、NOS(r=0.398,P<0.05)均为正相关;IIEF-5总分与NO(r=0.402,P<0.05)、NOS(r=0.423,P<0.05)均为正相关。结论:OSAHS导致的ED患者与患者外周血NO和NOS水平变化情况的具有相关性,且呈正相关,说明外周血NO和NOS水平的降低是OSAHS导致ED的内在病理基础。
Objectives：To investigate the clinical correlation of NO and NOS with ED caused by OSAHS.Methods：60 ED patients combined with OSAHS diagnosed by polysomnography meter（ PSG） and nocturnal penile erectile function test（ NPT） were selected as ED group and 30 healthy volunteers were randomly selected as healthy group to analyze serum NO and NOS levels of the two group as well as the serum NO,NOS levels,penile blood volume rate of change and IIEF-5 score differences of mild,moderate and severe ED groups.correlation analysis was done between penile blood volume and rate of change IIEF-5 scores the mild,moderate and severe ED groups and the serum NO and NOS levels.Results：Peripheral blood NO and NOS levels of ED group were lower than those of non-ED group and healthy group,the difference was statistically significant（ P 0 05）.Penile blood volume change rate and NO（ r = 0.356,P〈 0 05.）,NOS（ r = 0.398,P〈 0 05.） were positive correlation;IIEF-5scores and NO（ r = 0.402,P〈 0.05）,NOS（ r = 0.423,P〈 0.05） were positively correlated.Conclusions：ED caused by OSAHS and peripheral blood levels of NO and NOS changes are positively correlated,indicating that reduction of peripheral NO and NOS levels are internal pathological basis of ED caused by OSAHS.
