RESUMEN
To investigate the effects of cigarette smoking in different manners on acute lung injury in rats.The commercially available cigarettes with tar of 1,5, 11 mg were smoked in Canada depth smoking (health canada method, HCM) manner, and those with tar of 11 mg were also smoked in international standard (ISO) smoking manner. Rats were fixed and exposed to mainstream in a manner of nose-mouth exposure. After 28 days, the bronchoalveolar lavage fluids from left lung were collected for counting and classification of inflammatory cells and determination of pro-inflammatory cytokines IL-1β and TNF-α. The right lungs were subjected to histological examination and determination of myeloperoxidase (MPO) and superoxide dismutase (SOD) activities and glutathione, reactive oxygen species (ROS) and malondialdehyde (MDA) levels.In both HCM and ISO manners, the degree of lung injury was closely related to the tar content of cigarettes, and significant decrease in the body weight of rats was observed after smoking for one week. In a HCM manner, smoking with cigarette of 11 mg tar resulted in robust infiltration of macrophages, lymphocytes and neutrophils into lungs, significant increase in IL-1β and TNF-α levels and MPO activities, and significant decrease in GSH levels and SOD activities and increase in ROS and MDA levels (all<0.05). Smoking with cigarette of 5 mg tar led to moderate increase in IL-1β and TNF-α levels, and MPO activities (all<0.05), and moderate decrease in GSH levels and SOD activities and increase of ROS and MDA levels (all<0.05). However, smoking with cigarette of 1 mg tar affected neither inflammatory cell infiltration nor IL-1β and TNF-α levels.Cigarette smoking in nose-mouth exposure manner can induce acute lung injury in rats; and the degree of lung injury is closely related to the content of tar and other hazards in cigarettes.

RESUMEN
It is important to overcome the problem of noise for the research and development of ventilator technologies. Previous research of this subject showed that the pressure generator, produced by German EMB-PAPST Company and specially used for continuous positive airway pressure (CPAP) ventilator, created noise easily, due to local backflow in the volute, uneven velocity distribution in the impeller and local negative pressure in the inlet of the impeller. Based on the previous research, a combination of the computational fluid dynamics (CFD) software FLUENT and steady-state solution of noise source of Reynolds-Averaged Navier-Stokes (RANS) was used in this study. We combined equation of Lilley and Synthetic Turbulence to get the information about speed fluctuation of the pressure generator, which is used to finish noise prediction. After detailed analysis, it showed that noise source of different degrees spreaded around the inlet of the impeller and the volute, interface of blade edge and corner of the volute tongue, which influenced its overall performance to certain extent. Therefore, its structural design needs to be improved.
