摘  要:目的探讨辅助诱导T淋巴细胞(Th)17/调节性T淋巴细胞(Treg)平衡在阻塞性睡眠呼吸暂停低通气综合征(OSAHS)中的作用及其机制。方法纳入2015年3月至2016年4月南通大学附属吴江医院睡眠实验室行多导睡眠监测(PSG)的患者100例,根据睡眠呼吸暂停低通气指数(AHI)分为单纯鼾症组及轻、中、重度OSAHS组,分别检测外周血单个核细胞中Th17、Treg比例(均为占CD4^+T细胞比例)及血清中白细胞介素(IL)-17A、IL-6水平,并与OSAHS相关参数进行相关性及多元逐步回归分析。结果轻、中、重度OSAHS患者Th17比例[(1.36±0.46)%、(1.68±0.30)%、(2.23±0.03)%比(1.02±0.22)%]、Th17/Treg比值(0.22±0.07、0.28±0.10、0.29±0.00比0.13±0.03)、血清中IL-17A水平[(2.53±0.89)、(2.99±1.96)、(7.77±1.63)比(1.45±0.78)ng/L]、IL-6水平[(6.14±4.37)、(9.41±4.66)、(12.58±6.65)比(5.44±3.13)ng/L]均显著高于单纯鼾症组;Treg比例均显著低于单纯鼾症组[(7.57±0.16)%、(6.46±1.57)%、(6.10±1.19)%比(8.02±1.45)%](均P〈0.05)。Th17比例、Th17/Treg比值、IL-17A及IL-6水平均与AHI、氧减指数(ODI)呈正相关,与最低SpO2呈负相关(均P〈0.05);Treg比例与AHI、ODI呈负相关,与最低SpO2呈正相关(均P〈0.05)。最低SpO2是影响Th17、Treg比例及Th17/Treg比值的最显著因素。结论OSAHS患者体内存在Th17/Treg平衡失调,Th17参与的炎症反应可能在OSAHS的发生发展中发挥重要作用。Objective To explore the role and the mechanism of Th17/Treg in obstructive sleep apnea hypopnea syndrome (OSAHS). Methods A total of 100 patients who completed polysomnography (PSG) in the sleep lab of Affiliated Wujiang Hospital of Nantong University from Mar. 2015 to Apr. 2016 were enrolled and divided into four groups (primary snoring as the control group, mild OSAHS, moderate OSAHS and severe OSAHS) according apnea hypopnea index (AHI). The proportion of Th17, Treg ( of CD4^+ T cells) and the expression of interleukin (IL)-ITA, IL-6 were detected and the relevant data were analyzed by the correlation analysis and the multiple stepwise regression analysis. Results Compared with the control group, the OSAHS patients had higher Th17% [ ( 1.36 ±0. 46) %, ( 1.68±0. 30) %, (2. 23 ±0.03)% vs (1.02 ±0.22)%], Th17/Treg [(0.22±0.07), (0.28±0.10), (0.29±0.00) vs (0. 13±0.03)], IL-17A [(2.53±0.89), (2.99±1.96), (7.77±1.63) vs (1.45±0.78) ng/L], IL-6 [(6.14±4.37), (9.41±4.66), (12.58±6.65) vs (5.44±3.13) ng/L] and lower Treg% [(7.57±0.16)%, (6.46±1.57)%, (6.10 ±1.19)% vs (8.02 ±1.45)%] (all P〈0.05). A positive correlation could be seen between Th17% , Th17/Treg, IL-17A, IL-6 and AHI, oxygen desaturation index (ODI) respectively, there was a negative correlation between Th17% , Thl7/Treg, IL-17A, IL-6 and the lowest oxygen saturation ( SpO2 ) ( all P 〈 0. 05 ). The proportion of Treg had a negative correlation with AHI or ODI and a positive correlation with the lowest SpO2 ( all P 〈 0.05 ). The lowest SpO2 was the most important factor which could influence Th17%, Treg% and the radio of Th17/Treg. Conclusions There is an imbalance of Th17/Treg in OSAHS. Therefore, Thl7 and the relevant inflammatory cytokines may be involved in the occurrence and development of OSAHS.
