67, the sensitivity and specificity were 75% and 72%, respectively.
CONCLUSIONS: Vessel invasion had the greatest impact on recurrence
in clinical stage IA non-small cell lung cancer. Our simple computed tomography image analysis showed good predictive performance for vessel invasion.”
“In the present Fludarabine ic50 study, the crude extract and its four fractions of petroleum ether, ethyl acetate, n-butanol, water from Pyrola incarnata Fisch. leaves were prepared and their antioxidant activities were investigated by using four antioxidant assays in vitro. The ethyl acetate fraction showed remarkably strong antioxidant activities on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, ABTS radical scavenging, reducing power and beta-carotene-linoleic acid SHP099 research buy bleaching, which were almost comparable to capacities of the positive controls (VC and BHT). The ethyl acetate fraction had the highest total phenolic and total flavonoid contents. Furthermore, Pearson correlation analysis was used to analyze the correlation. According to the results, a significant correlation between total
phenolic contents and antioxidant activities were observed. At last the ethyl acetate fraction was analyzed by HPLC. Eight kinds of phenolic compounds were identified by ESI-MSn. (C) 2013 Elsevier B.V. All rights reserved.”
“Objective: Traditionally, laser supraglottoplasty for the treatment of severe laryngomalacia (SLM) is via rigid endoscopy (RE). Potassium-titanyl-phosphate (KTP) laser fiber can pass through a flexible endoscopy (FE) and cauterize tissue. This study is designed to evaluate and compare clinical variables between these two techniques in the treatment of SLM in infants.
Methods: A retrospective study includes four-year period of consecutive infants who received laser supraglottoplasty. In the first two years (2006-2007), conventional RE CO(2)-laser with general anesthesia and endotracheal intubation
were used. In the latter two years WZB117 (2008-2009), a novel technique of FE KTP-laser with intravenous sedation, nasopharyngeal oxygen and a noninvasive respiratory support (if indicated), without any artificial airway was used immediately after the diagnostic FE. After laser surgery, infants were followed for three months. Clinical variables were analyzed and compared.
Results: A total of 57 infants (27 in RE group, 30 in FE group) were enrolled. Basic variables were similar between both groups. Clinical improvement was comparable with 88.9% and 93.3% in the RE and FE groups, respectively. There are no significant differences in mean number of laser surgery, major complications, duration of post-laser respiratory support and hospitalization days, body weight percentile between the two groups. However, the durations of waiting time, operation, ET intubation and total hospital days were significantly less in the FE group.
