Results There was a linear regression relationship between the course of the disease, smoking index of asthma patients and the improvement rate of FEV1.
结果 1。哮喘患者病程、吸烟指数与支气管舒张试验中FEV1改善率有线性回归关系；

Symptom score and pulmonary function expressed as peak expiratory flow(PEF), peak expiratory flow rate (PEFR) and forced expiratory volume in one second (FEV1) were recorded.
观察两组每日症状评分，早、晚最大呼气峰流速测定（PEF），肺功能检查（FEV1）。
Result:The FEV1 and the percentage of FEV1 in two groups after treatment was superior to that before treatment, and there was significant difference in them respectively(P<0.05).
结果：两组患者FEV1、FEV1百分比均较治疗前改善，治疗前后比较差异具有统计学意义（P〈0.05）；
Among the 39 patients who completed the study, albuterol resulted in a 20% increase in FEV1, as compared with approximately 7% with each of the other three interventions (P<0.001).
结果 在39例完成研究的病人中，沙丁胺醇导致FEV1增加20%，与之相比，其他3 种干预的每一种大约增加7%（P＜0.001）。
Conclusion IOS determine respiration impedance is a sensitive marker of judgement air velocity obstruction, it can replace FEV1 judge the degree of COPD patients airway obstruction.
结论IOS法测定呼吸阻抗是判断气道阻塞的敏感指标，可以代替FEV 1判断COPD患者的气道阻塞程度。
Among both groups, the mean prebronchodilator FEV1 decreased from 3.14 l to 2.84 l, but the predicted value remained at exactly the same level of airway function (89% of predicted).
两组患者之间，支气管扩张剂使用前的FEV1平均值从3.14升减少到2.84升，但是预测值仍然恰好在气道功能的相同水平（89%预测值）。
Although albuterol, but not the two placebo interventions, improved FEV1 in these patients with asthma, albuterol provided no incremental benefit with respect to the self-reported outcomes.
结论在这些哮喘病人中，尽管沙丁胺醇(而不是两种安慰剂干预)可改善FEV1，但沙丁胺醇在自我报告的转归方面没有提供额外的益处。
Results Symptoms and pulmonary function (FEV1, MMEF) of the patients were improved obviously in the treated group. While the observed indexes were not significantly changed in the control group.
结果治疗组病人的症状及肺功能(FEV_1、MMEF)有明显改善，而对照组各项观察指标均无显著变化。

在研究期间，被指定接受布地奈德的吸烟患者使用支气管扩张器后FEV1值平均下降192.4ml，而非吸烟者平均下降134.3 ml。
Methods: Healthy, athletic subjects who are suspected of having exercise-induced bronchospasm were recruited, and FEV1 values were determined following provocative airway challenges with methacholine.
方法：受试的对象为可疑的运动诱导的支气管痉挛的健康、体格健壮的个体，用乙酰胆碱激发气道反应后，测定一秒钟用力呼气量。
