1有机小分子发光材料与聚合物发光材料在大气存放条件下的稳定性对比研究显示文摘分别采用紫外光电子能谱 (UPS)、X光电子能谱 (XPS)、原子力显微镜 (AFM )、以及光致发光光谱(PL)等方法对在大气存放条件下的 8 羟基喹啉铝 (Alq)薄膜和聚 ( 9,9 二辛烷基芴 ) (PFO)薄膜的电子结构、表面形貌以及发光特性进行了对比研究。研究结果表明 ,PFO的电子结构、表面形貌以及发光特性受外界气氛影响极小 ,是一种非常稳定的聚合物发光材料。这为聚合物发光器件的稳定性提供了有利的条件。徐正 廖良生 李振声 李述汤 Inbase karan M Woo E P Wu W W 2000发光学报2000,21,3:3
2Performance characteristics of retrograde single-balloon endoscopy: A single center experience显示文摘AIM: To evaluate the technical success, diagnostic yield(DY) and therapeutic potential of retrograde single balloon enteroscopy(rS BE). METHODS: A retrospective review of 136 rS BE procedures performed at a tertiary academic referral center from January 2006 and September 2013 was completed. Patient characteristics including age, gender and inpatient status were collected. The indication for the procedure was categorized into one of three groups: Obscure gastrointestinal bleeding(GIB), evaluation for Crohn's disease and abnormal imaging. Procedural characteristics including insertion depth(ID), procedure time, concordance with pre-procedural imaging and complications were also recorded. Lastly, DY, defined as the percentage of cases producing either a definitive diagnosis or findings that could explain clinical symptoms and therapeutic yield(TY), defined as the percentage of cases in which a definitive intervention was performed, were determined. Mucosal tattooing and biopsy alone were not included in the TY. RESULTS: A total of 136 rS BE procedures were identified. Mean patient age was 57.5(± 16.2) years, 67(49.2%) were male, and 110(80.9%) procedures were performed on an outpatient basis. Indications for rS BE included GIB in 55(40.4%), evaluation of inflammatory bowel disease(IBD) in 29(21.3%), and imaging suggestive of pathology other than GIB or IBD in 43(31.6%). Nine(6.6%) rS BEs were performed for other indications. Mean ID was 68.3(± 39.3) cm proximal to the ileocecal valve and mean time to completion was 41.7(± 15.5) min. Overall, 73(53.7%) cases were diagnostic and 25(18.4%) cases were therapeutic in which interventions(argon plasma coagulation, stricture dilatation, polypectomy, etc.) were performed. Pre-procedural imaging was performed in 88(64.7%) patients. Endoscopic concordance of positive imaging findings was seen in 31(35.2%) cases. Follow up data was available in 93(68.4%) patients; 2(2.2%) reported post-procedural abdominal pain within 30 d following rS BE. There were no other reported complications. CONCLUSION: rS BE exhibits an acceptable diagnostic and TY, rendering it a safe and effective procedure for the evaluation and treatment of small bowel diseases.Kaci E Christian Karan Kapoor Eric M Goldberg 2016World Journal of Gastrointestinal Endoscopy2016,8,15:2
