The results showed:(1) Chronic cigarette smoking down-regulated the protein synthesis and mRNA expression of BKca and Kv1.5 in bronchial and bronchiolar smooth muscles.

结果显示：(1)慢性吸烟可降低大鼠大气道和小气道BKca和Kv1.5蛋白和mRNA表达。

In bronchi and bronchioli smooth muscles.(5) There were no difference between protein expression of these two potassium channels when examined in whole lung tissue.

慢性吸烟下调大鼠气道平滑肌BKca和Kv1.5的表达水平，可能是导致气道高反应性的机制之一。

多伦多大学医学院外科及生理学系，加拿大多伦多M5G 2C4哮喘是一种梗阻性肺疾病，以支气管收缩、持续性气道炎症和气道重塑为特征。

Their pulmonary function and bronchodilatation test were checked and compared.

支气管哮喘缓解期老年患者的气道受限、可逆性都比青年患者差，提示缓解期气道炎症仍然持续存在，需长期维持治疗，定期复查肺功能有助于指导治疗。

Results: In the senile asthmatic patients during their alleviative period, 91.67% had abnormal pulmonary function and 58.33% had positive reaction in bronchodilatation test.

支气管哮喘缓解期老年患者的气道受限、可逆性都比青年患者差，提示缓解期气道炎症仍然持续存在，需长期维持治疗，定期复查肺功能有助于指导治疗。

Use intermittent positive pressure ventilation mode in ALI dogs, calculate Elastance and Resistance, then change to PAV, set the assist ratio 80％、60％、40％、20％randomly, Observe the changes of respiratory mechanics、blood gas analysis and hemodynamics during mechanical ventilation.

结果：随着辅助比例的增加气道峰压、气道平均压、潮气量、呼吸机呼吸功均增加，犬呼吸功减少。

The lung ventilation capacity (FEV1.0%, MVV%), the degree of airflow obstruction (FEV1.0/FVC%), emphysematous extent, peripheral airway resistance, total airway resistance (R5) and total respiratory resistance of the phlegm-syndrome group (the PDL group and the PHAL group) changed slightly and their sickness conditions are the best to cure; While the LKD group is the most serious sickness.

痰证组（痰湿蕴肺组和痰热蕴肺组）患者的肺通气功能（FEV1.0%、MVV%），气流阻塞程度（FEV1.0/FVC%），肺气肿程度，气道周边阻力、总气道阻力、呼吸总阻抗（Rp、R5、Zrs）改变最小，病情最轻；肺肾两虚组患者病情最重。

Methods 58 cases patients needing endocardiac orthoptic surgery were enrolled in this study, they are divided into control group and SFI group randomly. Injecting of SFI 1ml/kg by intravenous before CPB was performed in group SFI, tidal volume, Pmax , Pmean and calculating Crs and RI during 10 min , 30 min , 60 min after the trachea intubating, in the beginning of CPB and during 10min, 60min, 120min after CPB were recorded.

选择临床心内直视手术病人58例，随机分为对照组和SFI组，SFI组于CPB前予SFI 1ml/kg静注，记录气管插管后10、30、60 min，CPB手术开始时，CPB停止后10、60、120min时的潮气量、气道峰值压、平均气道压并肺顺应性和呼吸指数。

Methods Twenty-three cases of OSAS patients proved by polysomnography were examined with MRI. The cross-sectional area of retropalatal region, retroglossal region, epiglottal region and the lateral parapharyngeal fat pad of RP region was calculated. The thickness of bilateral and posterior pharyngeal wall and other indices were also measured. 30 nonsnoring age-matched normal subjects were selected as the control group. 15 patients underwent turbo field echo T1-weighted imaging during sleep. The images of RP, RG, and EPG were analyzed. Results In oSAS group, the cross sectional area of RP and RG regions was smaller than that of the control group.

应用MRI对23例经多导睡眠监测（polysomnography， pSG）确诊的OSAS患者及30例无打鼾的健康成人进行上气道检查，于轴面图像测量软腭后区（retropalatal region， RP区）、舌根后区（retroglossal region， RG区）和会厌区（epiglottal region， EPG区）的气道截面积，各区前后、左右径及其比值，各区咽侧壁、咽后壁软组织厚度，RP区咽旁间隙（lateral parapharyngeal fat pad，LPFP）截面积，于正中矢状面图像测量软腭厚度、长度及截面积，对两组各项检查指标进行统计学分析。

RESULTS: It was found that the curative effects on squamous cell carcinoma in the near future were better than those on other pathologic types, on hypovascular lung cancer were superior to those on hypervascular cancer, on carcinomas in larger airways were better than those on carcinomas in smaller airway, and the effects of multiple treatment were better than those of one treatment.

结果： 鳞癌的近期疗效明显优于其他病理类型；乏血管型的近期疗效明显优于富血管型者；大气道肿瘤的近期疗效优于小气道者；多次治疗的近期疗效优于单次治疗者；临床分期的近期疗效与治疗效果无关。
