Objective To determine how endoscopic retrograde cholangiopancreatography (ERCP) compared with magnetic resonance cholangiopancreatography (MRCP) in the diagnosis of pancreaticobiliary diseases. Methods A total of 40 patients with suspected pancreaticobiliary diseases underwent both MRCP and ERCP. Images obtained from ERCP and MRCP were compared. Results Pictures of both the examinations in the 40 patients had come out satisfactorily revealing the pancreatic duct and the biliary tree. The sensitivity, specificity and accuracy were 87% (34/39), 100% (1/1) and 88% (35/40) in MRCP and 100% (39/39), 100% (1/1) and 100% (40/40) in ERCP, respectively, without significant differences between the two examinations. Conclusions Although MRCP offers a diagnostic means equivalent to ERCP, it cannot take the place of the latter as regards identification of biliary obstruction.

OBJECTIVE:
To study dynamic change and pathophysiology of airway obstruction of the soft palate in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) during wakefulness and natural sleep.
METHOD:
Sixteen patients who were diagnosed as OSAHS by sleep questionnaires, medical examination and polysomnography were enrolled in this study in Shanghai Tenth People' Hospital from May to December during 2007. All patients were requested to keep awake prior to examination. Sequential midline sagittal images of the upper airway were obtained during awake and asleep state with Cine-MRI and been transmitted to portable computer. Morphologic change of the soft palate, the anterior-posterior pendulum angle of the soft palate, the anteroposterior diameter and the length of soft palate were measured. Statistical analysis was performed with paired t-test.
RESULT:
During wakefulness: soft palate caused obstruction by floating backwards and widening anteroposterior diameter(distance between hard palate and uvula P > 0.05, included angle of hard palate and segmental vente of uvula P < 0.05, included angle of hard palate and segmental dorsum of uvula P < 0.01, difference of included angle P < 0.01). Main obstruction site was on retropalatal region. During natural sleep: soft palate caused obstruction by lengthening down and widening anteroposterior diameter (distance between hard palate and uvula P < 0.01), included angle of hard palate and segmental vente of uvula P > 0.05, included angle of hard palate and segmental dorsum of uvula P > 0.05, difference of included angle P < 0.01). Main obstruction site was on retroglottal region.
CONCLUSION
Morphologic change of soft palate in patients with OSAHS is multiple, and level of obstruction is deeper during natural sleep than during wakefulness. Main reason of airway obstruction is distinct during different state. The obstruction of upper airway of patients with OSAHS during wakefulness can't replace that during natural sleep.

Objective To analyze the causes of unplanned tracheal extubation in mechanically ventilated patients in the pediatric intensive care unit using quality management practices and observe the changes of extubation rates before and after implementing these practices.Methods In the first place,we set up quality management group in June 2014.Second,the team formulated a risk factor checklist for unplanned tracheal extubation based on literature research, and analyzed the main causes requiring tracheal extubation. The last time,we developed some management measures for important reasons in 2014,and established and implemented a quality management strategy between 2015 and 2016.The incidence frequency of unplanned tracheal extubation,i. e. the number of extubation cases per 100 days with a tube in place(mechanical ventilation days),was used to evaluate the change of the extubation rates before and after implementing the new measures. The cases in 2014 were retrospectively analyzed,and cases from 2015 to 2016 were prospectively collected.The number of interval days for two continuity unplanned extubation was considered to be a means of quality control.Results Rick factors associated with unplanned extubation in the pediatric intensive care unit before implementing quality management were a delay of the replacing adhesive bandage, lack of sedation assessment,which were related to frequent physician replacement and insufficient training and supervision.In consideration of the identified risk factors,a standard operating procedure was formulated to prevent unplanned extubation,including standard operating procedure of tracheal catheter fixation and the sedation assessment. There were 484 mechanical ventilation in 2014,and the incidence of unplanned extubation was 0.8%,and the median number of days of separation was 8.0(4,20) d.Between 2015 and 2016,there were 1 379 mechanical ventilations,and the incidence of unplanned extubation was 0.2%,and the median number of days of separation was 34.0(19,61) d.The incidence of unplanned extubation in 2015 to 2016 was lower than that in 2014(χ2=5.936,P=0.018).Ramsay scoring usage increased from 28.6% in 2014 to 57.1% between 2015 and 2016,while Ramsay scored 3-4 points from 2015 to 2016 was higher than 2014(P< 0.05).Conclusion Establishing the quality management group according to the requirements of each hospital and implementing quality management strategies can reduce the incidence of unplanned extubation,thereby improving the quality of care in pediatric intensive care unit.

Objective:To investigate the value of pericoronary adipose tissue histogram parameters based on coronary CT angiography (CTA) images for the differentiation of acute coronary syndrome and stable coronary artery disease.Methods:The clinical data and CTA images of 93 patients with coronary CTA examination in Suzhou Kowloon Hospital from 2013 to 2018 were analyzed retrospectively. There were 39 patients with acute coronary syndrome (acute coronary syndrome group) and 54 patients with stable coronary artery disease (stable coronary artery disease group). A region of interest (ROI) was drawn around the stenosis of the coronary arteries, with CT attenuation ranging from-190 to -30 HU to exclude non-adipose tissue. The CT attenuation of ROI excluding non-adipose were measured and histogram analysis was performed. The obtained parameters included the mean value, median value and the 5th, 10th, 45th, 55th, 70th and 95th percentiles. The differences in histogram parameters between the two groups were compared, and then the value of each parameter in differentiating acute coronary syndrome and stable coronary artery disease was evaluated based on receiver operating characteristic (ROC) analysis. The stepwise regression of multivariate logistic regression analysis was used to identify the useful features and establish the final prediction model. The ROC curve of the final model was calculated and its value was analyzed.Results:The mean, median and the 5th, 10th, 45th, 55th,70th and 95th percentile differences between the acute coronary syndrome group and the stable coronary artery disease group were statistically significant (all P<0.05). The ROC curve for the median and the 95th percentile had the same area under curve (AUC) of 0.73. The sensitivity, specificity and AUC of the diagnostic model established by multiple logistic regression were 82.1%, 89.1% and 0.90 respectively. Conclusion:CT attenuation histogram of pericoronary adipose tissue is of high value in differentiating acute coronary syndrome from stable coronary artery disease.
