Objectives To compare the efficacy and adverse effects of combining all-trans retinoic acid and arsenic triox-ide with or without anthracyclines on the treatment of childhood acute promyelocytic leukemia (APL) patients. Methods The retrospective study included 46 children as newly diagnosed APL from January 1st, 2001 to December 31st , 2012. Efficacy and adverse effects for different induction therapies and in high and low white blood cell (WBC) count subgroups were studied. Results In the non antharcycline containing group, 2 patients died during remission induction, and in the antharcycline containing group none of the patients died. No statistical difference was observed between the antharcycline containing group and the non antharcycline containing group in complete remission, the length of time to achieve molecular complete remission and minimal residual disease quantitative analysis at the end of the induction. The mean duration of high WBC count subgroup in the anthar-cycline containing group was shortened than that of the non antharcycline containing group (P<0.05). The recovery time of the abnormal coagulation was found similar between these two groups. Conclusions The use of antharcycline in induction therapy could shorten the duration of high WBC count and reduced the WBC count peak , thus reduces the risk of early death.

Objective To investigate the genetic characteristic of whole-genome of influenza A/H3N2 viruses in severe acute respiratory infection cases in Beijing area.Methods From 2014 to 2016,the viral RNA was extracted from 32 strains isolated from SARI cases,then sequenced by Ion Torrent PGM Sequencer.The phylogeny and molecular features of whole-genome were analyzed by Mega and Consurf software.Results The HA gene of tested strains isolated in 2014-2015 influenza season belonged to lineage 3C.3a and 3C.2a,while those isolated in 2015-2016 influenza season belonged to cluster 3C.2a.Moreover,compared with the vaccine strains,7 variant amino acids of protein of HA1 were identified,and two of them were located in antigenic sites.All isolates were sensitive to neuraminidase inhibitors while showed resistance to blockers for M2 ion channel.Conclusion The phylogenetic features of isolates studied in this study are similar with that of current circulating strains.However,the difference between isolates and vaccines should not be overlooked.
