ConclusionMost OSAHS patients are old and with retrolingual obstruction, also they have worse disturbance sleep with a high AI and a low HI.

结论伴有舌根平面阻塞的患者整体年龄偏大，睡眠结构紊乱较重，呼吸事件中呼吸暂停较多，低通气较少。

To evaluate the effect of retrolingual obstruction on polysomnograhy of patients with obstructive sleep apnea hypopnea syndrome. Methods230 OSAHS patients proved as OSAHS by PSG were divided into two groups: the retrolingual obstruction group and the nonretrolingual obstruction group.

Objective To study the effect of techknowledge of subglottic secretion clean up to reduce the rate of ventilatorassociated pneumonia.

目的 观察气囊上滞留物清除技术对降低机械通气患者呼吸机相关性肺炎发生率的作用。

We compared conventional and continuous aspiration of subglottic secretions procedures in ventilated patients after major heart surgery.

我们在重大心脏手术后通气患者中对常规和连续声门下气道分泌物抽吸操作进行比较。

Methods Fiftyeight patients were divided into two groups. The observation group (n=32) was treated with techknowledge of subglottic secretion clean up and the control group(n=26) received routine airway care.

将58例行气管插管机械通气治疗48 h以上患者随机分为观察组(32例)和对照组(26例)，对照组采用常规气道护理，观察组在此基础上实施气囊上滞留物清除技术。

Results Thirty-one(7.64%) of 406 patients showed abnormal ventilatory function, while 165 of 404 patients showed diffusing abnormality. Of the 434 patients who had received HRCT scans,151(34.79%) showed abnormalities including subpleural and basal ground-glass and reticular attenuation,nodular septal thickening and bronchiectasis. Of the 395 patients who had received both lung function test and HRCT scanning,55(13.92%) had abnormalities both in the lung function and HRCT.

结果 在4 0 6例进行肺通气功能检测的患者中，31例(7 6 4 %)异常；4 0 4例进行肺弥散功能检测，其中16 5例(40 84 %)异常；4 34例进行胸部HRCT检查，15 1例(34 79%)异常，表现为磨玻璃密度阴影、网格状阴影和胸膜下弧线影等；395例同时接受肺弥散功能检测和胸部HRCT检查，5 5例(13 92 %)两项均异常，且HRCT显示双肺病变典型者的肺弥散功能较HRCT正常者有显著的下降，两组差异有统计学意义。

Pulmonary function tests showed restrictive ventilation disturbance and/or a decreased diffusing capacity in 12 patients and normal condition in 4 patients. Chest X-ray films showed multiple patchy consolidation in 12 patients and thickening of lung markings in 4 patients. HRCT scans demonstrated patchy consolidation and/or ground-glass opacity in 16 patients and fine nodular consolidation in 4 patients. The lesions were diffuse in 1 patients and had a predominantiy subpleural and/or peribron chovascular distrbution in 15 patients.

结果：14例患者主要表现为干咳和气短，2例主要表现为发热伴咳嗽。12例患者肺功能检查表现为限制性通气功能障碍和弥散功能减低，4例肺功能正常。12例患者X线胸片呈多发斑片实变影，4例表现为纹理增粗。16例患者HRCT扫描表现为多发斑片实变影和磨玻璃影，4例伴小结节。1例病变弥漫分布于双肺，15例病变位于胸膜下和沿支气管血管鼠分布。
