【摘要】

：

影响上呼吸道通气功能的主要因素是呼吸气流变化。此研究旨在通过计算流体动力学模拟观察Angle Ⅱ1伴下颌后缩处于生长期患者经双HE垫治疗后咽部气流变化特征。锥形束CT扫描已完成双HE垫矫治的30例患者及尚未接受双HE垫矫治的30例患者，以重建咽部形态。经计算流体动力学模拟，进一步分析咽部气压下降与咽部形态学参数之间相互关系。在吸气过程中，我们发现最小气压出现在咽喉；而气压下降最大值及速率最大值出现

睡眠呼吸暂停的生物标记物检测及意义

多导睡眠图(PSG)是诊断OSAHS的金标准，但因其耗时费力、院外等待时间长，很多患者得不到及时诊治，且用其反复监测来判断病情进展和疗效并不现实。应用生物学标志物来判断病情进展和评估疗效要比反复PSG监测更直观便捷，如CPAP作为OSAHS的首选治疗，其依从性差仍然是临床医师面临的挑战，应用生物学标志物及时评价疗效以强化治疗动机无疑是提高依从性的重要策略之一。
