In view of the current conditions and reasons about the reform of medical and health system in China,the paper expounds the feasibility of authorized operation with state-owned assets of public hospital and the concrete operational pattern from the angle of hospital operational mechanism, which proposes a new idea about how to effectively solve the contradiction between the limited investment on state-owned health resources and the growing demands on medical health.

Objective To evaluate the value of ultrasound-measured changes in diaphragmatic excursion (DE) in predicting successful weaning from mechanical ventilation during the spontaneous breathing trial (SBT).Methods Sixty-three patients of both sexes,who were mechanically ventilated for more than 24 h and screened for ascertained readiness to wean,aged 45-64 yr,were enrolled in the study.Bilateral DE was measured using ultrasound at 0,10 and 30 min of SBT.The patients who successfully completed 30 min of SBT were extubated.The patients were divided into either success group or failure group according to whether or not weaning was successful.Receiver operating characteristic (ROC) curves were used to evaluate the value of bilateral △DE30-10 in predicting successful weaning.Results There were 48 cases in success group and 15 cases in failure group.Bilateral △DE30-10 was significantly higher in failure group than in success group (P＜0.05).The area under the ROC curves of the right △DE30-10 in predicting successful weaning was 0.958,＜0.175 cm was used to predict successful weaning,and the sensitivity and specificity were 93.3％ and 87.5％,respectively.The area under the ROC curves of the left △DE30-10 in predicting successful weaning was 0.903,＜0.275 cm was used to predict successful weaning,and the sensitivity and specificity were 80.0％ and 89.6％,respectively.Conclusion The fight △DE30-10 measured using ultrasound can serve as an assistant index in predicting successful weaning from mechanical ventilation during SBT.
