阻塞性睡眠呼吸暂停低通气综合征(OSAHS)为临床常见睡眠障碍类型,可引发低氧血症、睡眠结构紊乱,占睡眠障碍的1/3~1/2[1-2],仅次于失眠,可严重影响患者生活质量。目前,OSAHS的确切发病机制尚不完全明确;有研究表明,OSAHS患者血清抵抗素、脂联素水平异常,二者可能在OSAHS的发生发展过程中发挥着重要作用[3-4]。普罗布考具有抗炎、调脂、抗氧化、抑制内膜增生、改善血管内皮细胞功能、抑制血管重构等作用,近年来关于普罗布考治疗OSAHS的研究报道较多。本研究旨在探讨普罗布考对OSAHS患者的影响,现报道如下。

3 讨论
近年来,睡眠医学取得快速发展,OSAHS作为常见睡眠障碍类型而备受睡眠医学研究者关注。OSAHS是一种全身性疾病,潜在危险性较大[6],可导致血氧分压降低、血二氧化碳分压升高,进而引发呼吸骤停、心力衰竭等,可严重影响患者身体健康和生命安全[7]。研究表明,OSAHS主要是由上气道解剖结构狭窄和呼吸控制功能失调所致,患者由于睡眠时呼吸中枢驱动性下降、咽扩张肌张力降低而导致吸气时咽腔负压增大、咽气道软组织被动性塌陷等[8-9]。

表6 AHI与OSAHS患者其他观察指标的相关性
研究表明,普罗布考可通过降低胆固醇合成、促进胆固醇分解而降低血清胆固醇及低密度脂蛋白水平;通过改变高密度脂蛋白亚型结构和功能而影响卵磷脂胆固醇酰基转移酶、胆固醇酯转移蛋白及载脂蛋白E功能,继而使脂质化的胆固醇/TC比例恢复正常等,促进血液中HDL-C的逆转运;通过抑制细胞间黏附因子和P选择素的表达而抑制单核细胞黏附于内皮细胞,从而发挥调脂和改善血管内皮细胞功能等作用[10-11]。
大量临床研究证实,OSAHS患者存在血清抵抗素、脂联素水平异常改变[12-13]。抵抗素是RSTN基因编码产物,属抵抗素样分子(RELM)家族,其是一种富含半胱氨酸的分泌蛋白,也是一种脂肪组织特异性分泌因子(ADSF)。抵抗素作为一种促炎性细胞因子,可有效抑制前体脂肪细胞向成熟脂肪细胞分化并通过负反馈作用使OSAHS患者体内抵抗素含量增多,在OSAHS的发生、发展过程中发挥着重要作用。此外,OSAHS由于胰岛素抵抗等而导致胰岛素水平升高,糖脂代谢紊乱可进一步导致抵抗素水平升高。脂联素是脂肪细胞分泌的一种内源性具有多种生物活性的多肽,其是一种胰岛素增敏激素,能有效改善胰岛素抵抗,可通过特异性结合骨骼肌或肝脏细胞膜上的G蛋白耦联受体1型或2型脂联素受体而调节脂肪酸氧化和糖代谢;此外,脂联素还可促进骨骼肌细胞脂肪酸氧化和糖吸收,增强胰岛素对糖原异生的抑制作用,进而抑制肝糖原生成,是脂质代谢和血糖稳态调控机制中的重要调节因子[14-15]。
本研究结果显示,治疗后观察组患者TC、TG、LDL-C、空腹胰岛素、HOMA-IR、AHI及血清抵抗素水平低于对照组,HDL-C、LSaO2及血清脂联素水平高于对照组,表明普罗布考能有效改善OSAHS患者血脂代谢、糖代谢及氧合状态,降低血清抵抗素水平,提高血清脂联素水平。本研究结果还显示,AHI与OSAHS患者血清抵抗素水平呈正相关,与OSAHS患者血清脂联素水平呈负相关,提示抵抗素、脂联素水平可能与OSAHS有关。
综上所述,普罗布考能有效改善OSAHS患者血脂代谢、糖代谢及氧合状态;AHI与OSAHS患者血清抵抗素水平呈正相关,与OSAHS患者血清脂联素水平呈负相关。但本研究样本量较小且观察时间较短,结果结论仍有待扩大样本量并延长观察时间进一步证实。
