We identified that in vitro ASM promotes fibrocyte chemotaxis and chemokinesis (distance of migration after 4.5 hours, 31 mum [2.9 mum] vs 17 mum [2.4 mum], P =.0001), which was in part mediated by platelet-derived growth factor (mean inhibition by neutralizing antibody, 16% [95% CI, 2% to 32%], P =.03) but not by activation of chemokine receptors.

该研究首次证明：在哮喘中，成纤维细胞存在于哮喘患者气道平滑肌间隔，并可以促进纤维细胞迁移。成纤维细胞在哮喘患者气道平滑肌增生及气道功能障碍过程的所起的作用仍有待研究。

Then, the effects of configuration parameters on performance of inlet/forebody were discussed in detail according the database built during optimization, and the result shows the cowl parameters and isolater height have more important effect on the general performance of inlet/forebody.The analysis method was developed to evaluate the performance of scramjet combustor in direct-connect test.

建立了进气道/前体性能评估方法，采用渐进优化方法在全空间和缩减空间内对进气道/前体进行了两轮优化，优化效果比较显著；根据优化中建立的数据库，深入分析了各构型参数对进气道/前体性能的影响，结果表明外罩构型参数和隔离段高度对进气道/前体综合性能有相对较大的影响。

The predominant pathological characteristics of the chronic airway inflammation are airway inflammation, airway remodeling, mucous hypersecretion and so on.

慢性气道炎症性疾病以气道炎症反应、气道重塑、黏液高分泌等为主要病理特征。

Methods: Raw,SGaw,FEV_1 and FVC were measured using body plethysmograph and after Salbutamol Aerosol were inhaled in 70 asthmatic patients,the changes of the above parameters were observed.Results: There was significant difference in Raw,SGaw and FEV_1 before and after inhalation of Salbutamol Aerosol(P.001,P.001 and P.05 respectively),but there was no significant difference in FVC.

支气管舒张试验是测定气道高反应性的标准方法之一，目前常用的肺功能参数是1 s用力呼气容积(FEV1)和用力肺活量，测定时患者需深吸气后用力呼气，易受主观因素影响，出现假象，采用体积描记仪测定气道阻力和比气道传导率则可避免上述不足。

In asthma guinea-pigs, FM could recover immunity inbalance, lighten allergic inflammation of bronchium and hypersusceptibility, inprove the body and bronchial circulation, and had no side-effect like glucocrticoids.

防喘合剂对豚鼠具有免疫调节作用，能控制气道变应性炎症，降低气道高反应性；改善气道局部及全身的循环状态；未见明显的激素样副作用。

This teehnology makes the pulmonary function test go well for children, especially for the children before school age, and also prorides a reliable basis for early diagnosis and early clinical treatment of respiratory diseases.In this paper, I will introduce the clinical applications of bronchiectasis test using impulse oscillometry for children.

脉冲振荡法(impulse oseillometry，10S)是近年来开展的一项肺功能检测，是以外部发生器产生矩形电磁脉冲，通过扩音器转变为各种频率的机械波作为测试源，叠加在被检者静息呼吸上，再通过计算机的复杂运算，可快速、精确得出呼吸系统总气道阻力、中心气道阻力、周围气道阻力和肺顺应性等各参数的数值。

The pharyngonasal, pharyngo oral and pharyngolaryngeal surface were measured, finally the differences of their pharyngeal surface were defined between the control group and the OSAS groups, also the differences among the mild, moderate and the severe OSAS groups.

对120例受试者行上气道CT扫描，分别测出鼻咽腔、口咽腔和喉咽腔截面积的大小，比较OSAS病人和正常人间上气道截面积的差别，以及轻、中、重度OSAS病人间上气道截面积的差别。

Materials and Methods Helical CT was performed with 3.0mm slice thickness and 1.0～1.2 pitch in 10 normal subjects and 36 patients with upper airway diseases. In the healthy group, the upper airway shaded surface display was processed by using different reconstruction interval (1.0～3.0mm) and upper threshold (0～-900HU), while in the patient group, SSD, RaySum and integrated 3D images were made respectively.

材料与方法对10例正常和36例上气道病变的患者进行轴位螺旋CT扫描，层厚3.0mm，正常组采用不同重建间隔、阈值作气道表面遮盖法重建，病变组分别作气道SSD、RaySum重建和叠加成像。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
