Using a sample of 401 European firms reporting pension and retirement expense during the period of 2006-2011, this paper finds negative abnormal returns around the pension project initiation by the International Accounting Standards Board (IASB). More importantly, the abnormal returns are more negative for firms with higher financial leverage and lower ratios of net periodic pension cost to net income, but less negative for firms in countries with weak creditor rights (CR) and infrequent use of the corridor approach under IAS 19. Additionally, the effects of financial leverage and the ratio of net periodic pension cost to net income on the abnormal returns are more pronounced for smaller firms. Overall, the results are consistent with the view that recognition of previously disclosed off-balance-sheet pension liabilities as required by IAS 19R increases debt contracting costs, and highlight the importance of considering firm size and CR in international tests of debt contracting theory.展开更多

This study was to investigate the survival difference between first-line first generation EGFR-TKIs and chemotherapy in patients with either Del19 or L858R, and to directly compare OS in these two mutation groups. Methods: Eligibles were all prospective and retrospective studies comparing EGFR-TKIs with conventional chemotherapy or receiving single agent EGFR-TKIs and demonstrating survival analysis based on mutation types. The primary outcome was OS measured as pooled hazard ratios (HRs). All measures were pooled using random- effects models and 95% confidential interval (95% CI) was calculated. Results: A total of 14 studies incorporating 1,706 patients with either Del19 or L858R were included. Enrolling patients with Del19 or L858R in randomized controlled trials (RCTs), first-line first generation EGFR-TKIs were associated with no OS benefit, compared with chemotherapy (pooled HR_TKI/Chemo for Del19: 0.82, 95% CI: 0.64- 1.06, P=0.14; pooled HR_TKI/Chemo for L858R: 1.15, 95% CI: 0.85-1.56, P=0.38). Direct comparison of Del19 with L858R receiving with first-line first generation EGFR-TKIs demonstrated no significant survival difference (pooled HR19/21: 0.88, 95% CI: 0.67-1.16, P=0.37). Conclusions: Among patients with advanced non-small cell hmg cancer (NSCLC) harboring Del19 and L858R, first-line first generation EGFR-TKIs demonstrated no survival benefit comparing with chemotherapy. Direct comparison between Del19 and L858R revealed no significant survival difference after first-line first generation EGFR-TKIs.展开更多
A new triterpenoid bisglycoside, named raddeanoside R19, was isolated from the roots of Anemone raddeana. Its structure was elucidated on the basis of ESI-MS, ^13C NMR, and chemical methods.

The effects of raddeanoside R119 on superoxide generation in human neutrophil were evaluated. The compound suppressed the superoxide generation induced by N-formyl-methionyl-leucyl-phenylalanine (fMLP), phorbol 12-myristate 13-acetate (PMA) and arachidonic acid (AA) in a different concentration-dependent manner.展开更多
