Objective To evaluate the efficacy and safety of locating the target bronchus and treating through the chest wall and airway intervention in 29 cases with lung abscess secondary to pulmonary bulla. Methods In 29 cases the lung abscess secondary to pulmonary bulla had a mean diameter of 14 cm, of which 25 with COPD. Implement-ing 4 different ways to locate the target bronchus of lung abscess: Preoperative pulmonary CT, conventional fiber bronchoscopy, and locating the target bronchus by infecting colored saline separately forward and backward. Under guiding of CT, the central venous catheter was inserted via chest wall into lung abscess, which had pus suction, lavage, medicine injection and continuous negative pressure suction and then under direct vision of bronchoscopy, all of the target bronchi of pulmonary absess were occluded with fibrin glue. Results All of the 29 cases, the target bronchi of lung abscess were localized by lung CT in 17, by conventional bronchoscopy in 23, and by infecting col-ored saline forward in 26 and backward in 24 respectively. Cured in 25 and improved in 3, the total effective rate was 96.6%. The adverse effects:chest pain in 3, pneumothorax in 2, pyothorax, pyopneumothorax, subcutaneous em-physema, the drainage catheter falling off and dislocating separately in 1. Conclusion It was simple, safe and effec-tive to treat lung abscess secondary to lung bulla through the chest wall and airway intervention.

Inhaled nitric oxide has been identified as a potent method for curing acute respiratory distress syndrome,high brood pressure and some illnesses related to the lung,but the high cost limits its application.The present study investigates the reason of the high cost of inhaled nitric oxide in the current application,and gives some advices on solving them by using pulsed arc discharge in clean air,reducing the price of nitrogen oxides analyzer and being compatible with the present ventilators.The perspective of inhaled nitric oxide was viewed as well.

Objective To apply Windows presentation foundation (WPF) to rapid access and report printing of medical data.Methods Data access was realized by abstracting database to form data structure through entity framework (EF) and mapping datasheet as attribute.Multipage printing was executed by using Flow Document Scroll Viewer as the container and putting contents into different paragraphs with the block element.Results EF of WPF decreased the frequency of database access by the program greatly,and the reaction speed of the program was increased significantly.Flow document could be used for data printing.Conclusion WPF enhances the efficiency of system development and the beauty of man-machine interface,and thus is worthy promoting for medical system and software development.
