Randomized Controlled Trial Comparative Study[Comparison of target controlled propofol infusion and sevoflurane inhalational anesthesia in laparoscopic cholecystectomy].
To compare the effects of propofol target controlled infusion (TCI) and sevoflurane inhalational anesthesia on the hemodynamics and postoperative recovery in patients undergoing laparoscopic cholecystectomy. ⋯ Propofol TCI and sevoflurane inhalational anesthesia are all effective in inducing good anesthetic effect, maintaining hemodynamic stability and ensuring rapid recovery, but propofol TCI causes lower incidence of PONV in operations such as laparoscopic cholecystectomy.

[Changes of work of breathing in patients with acute exacerbation of chronic obstructive pulmonary disease during non-invasive positive pressure ventilation].
To investigate the effect of non-invasive positive pressure ventilation (NIPPV) on the work of breathing (WOB) in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). ⋯ NIPPV can relieve the load of the inspiratory muscles in patients with acute exacerbation of COPD, and the WOB of the inspiratory muscles can be reduced by PSV, H-PEEP and H-PS (by 75%, 71% and 76%, respectively), but higher PSV during NIPPV can cause higher WOB of the exspiratory muscles.

[Three-dimensional white matter tractography based on diffusion-tensor magnetic resonance imaging].
To assess the value of white matter fiber tractography based on magnetic resonance diffusion-tensor imaging (MR-DTI), a new noninvasive technique that helps estimate the structural connectivity of the brain, in understanding the anatomy of the white matter fiber tract. ⋯ A set of detailed white matter fiber anatomy maps of the normal brain is obtained by means of single-shot echo-planner diffusion tensor imaging at high resolution. This technique allows rapid visualization of the white matter tracts in vivo, and provides a new reliable means for studying fiber connectivity in the brain.

[Assessment of early-stage physiological response to acute lung injury in canine models using balloon catheter system for measuring esophageal and gastric pressure].
To explore feasible and reliable methods for estnbolishment and of acute lung injury model in animal models. ⋯ Application of balloon catheter system for measuring esophageal and gastric pressures allows objective evaluation of the various physiological responses in early stage of acute lung injury.

[Cellular immunity characteristics in drug abusers with pulmonary tuberculosis].
To explore the characteristics of cellular immunity in drug abusers with pulmonary tuberculosis. ⋯ Drug abuse might depress cellular immunity in patients with pulmonary tuberculosis, which further complicate the treatment of this disease.
