项目摘要
Obstructive sleep apnea (OSA) is associated with increased cardiovascular mortality, and oxidative stress was suggested to play an important role. The plasma thioredoxin (TRX) level is a novel oxidative stress market Adiponectin is an adipocyte-derived molecule with anti-inflammatory property. Plasma TRX and adiponectin levels were measured in 41 patients with severe OSA before (n=41) and after (n=27) nasal continuous positive airway pressure (nCPAP) therapy for one month and 12 subjects without OSA (Non-OSA group). The TRX level was significantly higher (p=0.02) and adiponectin level was significantly lower (p=0.02) in the OSA group than in the Non-OSA group. After one month of nCPAP treatment (n=27), the TRX level significantly decreased (p=0.03) and adiponectin level significantly increased (p=0.03). Among the 53 subjects (41 OSA + 12 Non-OSA subjects), the TRX level was positively correlated with respiratory disturbance index (p=0.002) and percentage of time with SaO_2<90% (p=0.002). The adiponectin level, but not the TRX level, was correlated with BMI (p = 0.02). Plasma TRX has the potential to be a unique marker for evaluating oxidative stress in OSA patients and monitoring the effectiveness of nCPAP therapy. Thus, OSA related hypoxemia (intermittent hypoxemia) which mimics reperfusion-reoxygenation may induce tissue injury as an oxidative stress. To investigate effects of intermittent hypoxia as an oxidative stress on cells, we made an instrument which had two chambers : hypoxia and normoxia chambers. Each chamber has preconditional medium equilibrated with gases : O2, CO2 and N2. Thus, putting cells into each preconditional medium, we can make intermittent hypoxia condition to cells. Using this instrument, we will do several cell experiments under intermittent hypoxia in the future.
阻塞性睡眠呼吸暂停(OSA)与心血管死亡率增加有关,氧化应激被认为起着重要作用。血浆硫氧还蛋白(TRX)水平是一个新的氧化应激市场脂联素是一种脂肪细胞衍生的分子,具有抗炎特性。检测41例重度OSA患者经鼻持续气道正压通气(nCPAP)治疗前(n=41)、治疗后(n=27)及12例非OSA患者(Non-OSA组)血浆TRX和脂联素水平。OSA组TRX水平显著高于非OSA组(p=0.02),脂联素水平显著低于非OSA组(p=0.02)。nCPAP治疗1个月后(n=27),TRX水平显著降低(p=0.03),脂联素水平显著升高(p=0.03)。在53例(41例OSA + 12例非OSA)患者中,TRX水平与呼吸紊乱指数(p=0.002)和SaO_2<90%的时间百分比(p=0.002)呈正相关。脂联素水平,而不是TRX水平,与BMI相关(p = 0.02)。血浆TRX有可能成为评估OSA患者氧化应激和监测nCPAP治疗有效性的独特标志物。因此,OSA相关低氧血症(间歇性低氧血症),其模拟再灌注-再氧合,可诱导组织损伤作为氧化应激。为了研究间歇性低氧作为一种氧化应激对细胞的影响,我们制作了一台具有低氧和常氧两个室的仪器。每个腔室具有用气体(O2、CO2和N2)平衡的预条件培养基。因此,将细胞置于各种预条件培养基中,可以对细胞造成间歇性缺氧条件。利用这台仪器,我们将在未来做几个间歇性缺氧下的细胞实验。
