Conclusions Transitional care can improve the quality of life of patients with COPD.

Objective To investigate the effect of bedside comprehensive ability training and critical thinking on the improvement of the personality maturity of pediatric nurses. Methods A total of 102 nurses with pediatric working years within one year were selected,and then they were arranged to receive critical thinking in combination with bedside comprehensive ability training for 6 months. After the training, pediatric nurses′ critical thinking ability, bedside comprehensive ability and personality maturity were evaluated. Results Before training, the total score of Critical Thinking Disposition Inventory-Chinese Version (CTDI-CV) , total score of bedside comprehensive ability, personality maturity score were 288.21±25.44, 75.24±2.51, 84.01±32.26, after training, they were respectively 324.18±25.93, 92.65±3.17, 125.57±35.47. Comparison of the scores before training and after training showed statistically significant difference(t=7.071, 30.750, 6.190,P < 0.05 or 0.01). Setting personality maturity as the dependent variable, and and CTDI-CV and bedside comprehensive ability as the independent variables, regression analysis showed that CTDI-CV and bedside comprehensive ability had a positive impact on the personality maturity. Conclusions The ability of pediatric nurses' critical thinking ability and bedside comprehensive ability training can promote the improvement of personality maturity of pediatric nurses.

Objective To investigate the diagnostic value of capsule endoscopy (CE), CT enterography (CTE), ileocolonoscopy and small bowel follow through (SBFT) for small bowel Crohn's disease (CD). Methods Fifty-seven consecutive patients with CD underwent ileocolonoscopy, CTE, CE, and SBFT. It included the presence of the following symptoms and signs: abdominal pain, weight loss,diarrhea, fever and positive fecal occult blood test. The location and the characteristics of intestinal and extra-intestinal lesions detected by four techniquks were compared. The proportions of patients with positive findings using each examination were compared. Results Of the 57 patients, 50 underwent ileocolonoscopy, terminal ileum lesion was found in 33 patients (66. 00% ), the remaining 17 (34.0%)were normal; among 34 patients who had CTE, 29 of small bowel lesion were found (85. 29% ); CE were performed in 27 patients, due to prolonged gastric transit one time, the capsule did not reach the cecum in one patient during battery lifetime. CE showed small bowel lesion in 26 patients (96.30% ); SBF was performed in 39 patients and 26 of small bowel lesion were detected (66. 67% ). CE had the highest diagnostic yield for CD and ileocolonoscopy had the lowest, and there were statistically significant difference among the 4 examinations (P = 0. 006 ). The combinded positive rates of two methods were: CE + CTE 92. 86% (13/14), SBFT + CTE 90. 91% (20/22), CE + ileocolonoscopy 95. 65% (22/23), CE + SBFT100% (17/17), ileocolonoscopy + CTE 89. 66% ( 26/29 ), ileocolonoscopy + SBFT 77.78% ( 28/36 ), but there were no significant differences between each two examinations. Conclusion CE, CTE have a higher yield in depicting mild to moderate finding of CD than SBFT. CE is better for assessing early mucosal disease,whereas CTE is better for detecting transmural and extraluminal abnormalities. Most important, CE plus CTE may depict nonobstructive CD of the small bowel when conventional techniques such as ileocolonoscopy or SBFF have negative or inconclusive finding. CE provides us explanations for the symptoms of patients, decision to follow up or therapy.

Objective To discuss the effects of repairing nasal ala defects by free transplantation of autogenous auricle composite tissue flap. Methods 50 cases with nasal ala defects were repaired by free auricular composite tissue flap transplantation from Janu 2003 to May 2013. The defects size was 0.5cm x 0.7cm~1.3cm x 1.5cm. According to the size of the defects, full thick wedge-shaped auricle composite tissue flap were cut off, then inserted into the nasal ala defects area and fixed stablely, the donor sites were sutured directly avoiding ear cartilage. Salvianolate and hyperbaric oxygen were used in postoperative treatment for 5-7 days. Results 48 cases achieved good results, 2 cases had partial necrosis of composite tissue flap after operation, also achieved good results after reoperation. Over 3 months~5 years follow-up, all cases had satisfactory results. The volume of auricle composite tissue flap reduced less than 10%. Surgical incisions had a linear scar, good color matching, nostril symmetry. All patients were satisfied with the overall appearance.

PurposeTo evaluate multislice spiral CT (MSCT) in diagnosing abdominal anaphylactoid purpura (AAP), and to explore its role in treatment follow-up.Materials and Methods Clinical and MSCT data of 13 patients with confirmed AAP were retrospectively analyzed. All patients underwent abdominal CT scan and thin layer reconstruction. Upper endoscopy was performed in 8 patients prior to treatment. MSCT was performed in 10 patients and endoscopy in 4 patients posttreatment, then clinical and CT features were compared to pretreatment findings.Results In pretreatment CT scan, single segment bowel involvement was found in 2 cases, multisegmental bowel involvement in 10 cases, and no positive finding in 1 patient. The duodenum and jejunum were involved in 8 patients and stomach in 5 patients. The diseased bowel wall showed swelling and thickening with decreased attenuation and homogeneous luminal narrowing with equivocal lining and double loop sign. Infiltration was found in 10 patients, small ascites in 3 patients. Patients were misdiagnosed as acute pancreatitis in 2 cases, acute cholecystitis, small bowel obstruction and peritonitis in 1 case respectively. Of 13 patients, five patients were cured, and the other 8 patients were improved. The clinical symptoms including rash, abdominal pain, occult blood, leukocytosis, vomiting, melena, urine occult blood were improved (χ2=5.59-18.33,P<0.05 orP<0.01). Post treatment CT showed significant improvement of bowel edema and infiltration (P<0.01). There was no statistically significant difference in change of ascites (P>0.05).Conclusion MSCT findings of AAP are nonspecific. CT diagnosis is difficult before skin rash. Combining CT characteristics of multisegmental bowel edema and clinical manifestations is helpful. CT examination can effectively follow up treatment response.
