Homoharringtonine is a safe and effective substitute for anthracyclines in children younger than 2 years

Frontiers of Medicine 2019, Volume 13, Issue 3,   Pages 378-387 doi: 10.1007/s11684-018-0658-4

Abstract: Homoharringtonine (HHT), a plant alkaloid from , exhibits a unique anticancer mechanism and has been widely used in China to treat patients with acute myeloid leukemia (AML) since the 1970s. Trial SCMC-AML-2009 presented herein was a randomized clinical study designed based on our previous findings that pediatric AML patients younger than two years old may benefit from HHT-containing chemotherapy regimens. Patients randomized to arm A were treated with a standard chemotherapy regimen comprising mainly of anthracyclines and cytarabine (Ara-C), whereas patients in arm B were treated with HHT-containing regimens in which anthracyclines in all but the initial induction therapy were replaced by HHT. From February 2009 to November 2015, 59 patients less than 2 years old with AML (other than acute promyelocytic leukemia) were recruited. A total of 42 patients achieved a morphologic complete remission (CR) after the first course, with similar rates in both arms (70.6% vs.72.0%). At the end of the follow-up period, 40 patients remained in CR and 5 patients underwent hematopoietic stem cell transplantation in CR, which could not be considered as events but censors. The 5-year event-free survival (EFS) was 60.2%±9.6% for arm A and 88.0%±6.5% for arm B ( =0.024). Patients in arm B experienced shorter durations of leukopenia, neutropenia, and thrombocytopenia and had a lower risk of infection during consolidation chemotherapy with high-dosage Ara-C. Consequently, the homoharringtonine-based regimen achieved excellent EFS and alleviated hematologic toxicity for children aged younger than 2 years with AML compared with the anthracycline-based regimen.

A subband excitation substitute based scheme for narrowband speech watermarking Article

Wei LIU, Ai-qun HU

Frontiers of Information Technology & Electronic Engineering 2017, Volume 18, Issue 5,   Pages 627-643 doi: 10.1631/FITEE.1601503

Abstract: We propose a new narrowband speech watermarking scheme by replacing part of the speech with a scaled and spectrally shaped hidden signal. Theoretically, it is proved that if a small amount of host speech is modified, then not only an ideal channel model for hidden communication can be established, but also high imperceptibility and good intelligibility can be achieved. Furthermore, a practical system implementation is proposed. At the embedder, the power normalization criterion is first imposed on a passband watermark signal by forcing its power level to be the same as the original passband excitation of the cover speech, and a synthesis filter is then used to spectrally shape the scaled watermark signal. At the extractor, a bandpass filter is first used to get rid of the out-of-band signal, and an analysis filter is then employed to compensate for the distortion introduced by the synthesis filter. Experimental results show that the data rate is as high as 400 bits/s with better bandwidth efficiency, and good imperceptibility is achieved. Moreover, this method is robust against various attacks existing in real applications.
