Abstract
This study investigates the effect of low miR-29b expression derived from bone marrow mesenchymal stem cells (BMSC) on AML. miR-29b expression in acute leukemia drug resistant cell line as K562/ADM was detected with RT-PCR. Cell proliferation was tested with MTT assay and apoptosis
was analyzed by flow cytometry. The correlation between miR-29b and PDGFRα level was analyzed. miR-29b expression was reduced after si-miR-29b transfection. PDGFRα expression was increased by the low miR-29b expression in AML cells so as to prompt the progression
of AML. Cell proliferation in K562/ADM was increased after miR-29b expression was reduced and quantity of apoptosis was decreased. There was a correlation of miR-29b and PDGFRα in the staging of AML (P <0.05). In conclusion, AML could be aggravated by the low miR-29b
expression possibly through regulating PDGFRα, resulting in increased drug tolerance.

Abstract
The fusion product of FIP1-like-1 (FIP1L1) and platelet-derived growth factor receptor α (PDGFRA) gene rearrangement is a tyrosine kinase oncoprotein sensitive to imatinib. This gene rearrangement characterizes a novel clinico-biological class of myeloid and lymphoid neoplasms with eosinophilia and PDGFRA abnormalities. The DEK proto-oncogene (DEK) and nucleoporin 214 (NUP214) rearrangement is rare in patients with acute myeloid leukemia (AML); therefore, the coexistence of DEK-NUP214 and FIP1L1-PDGFRA rearrangements in patients with AML is extremely rare. The present study presents a rare relapse case of a patient with AML with DEK-NUP214 and FIP1L1-PDGFRA rearrangements, without marked eosinophilia in the peripheral blood or bone marrow. Low-dose imatinib monotherapy without intensive chemotherapy was used to achieve complete hematological remission.

Abstract
Identification of gene fusion is an essential part in the management of patients with acute leukemia, not only for diagnosis but also in predicting the treatment outcome and selecting appropriate treatment. Adopting next-generation sequencing (NGS) technology for identification of gene fusion in patients with acute leukemia can be a good alternative to conventional tests. In the present study, the NGS RNA fusion gene panel test was applied to diagnostic samples of patients with acute leukemia to identify fusion genes more efficiently. Among 134 patients with acute leukemia, 53 gene fusions were detected in 52 patients. In addition to the recurrent gene fusions specified in the WHO diagnostic criteria, 11 rare or novel gene fusions were identified. Of those, two were gene fusions associated with Philadelphia-like acute lymphoblastic leukemia (Ph-like ALL), two were novel gene fusions, three were gene fusions with novel partner genes, and six were rare gene fusions from previous reports. We confirmed the clinical utility of the NGS test in identifying clinically significant gene fusions such as gene fusions involving KMT2A that has a large number of partners. Notably, Ph-like ALL-associated gene fusions could be easily identified despite the wide variety of genes involved. The results from the present study may contribute toward a better understanding of the genomic landscape of acute leukemia as well as patient management.

Abstract
Background Invasive fungal infections (IFIs) are a life-threatening problem in immunocompromised patients. Despite timely diagnosis and appropriate antifungal therapy, clinical outcomes of IFIs remain unsatisfactory, necessitating treatment with a combination of antifungal agents. Therefore, childhood leukemic patients treated with voriconazole plus caspofungin were evaluated for the safety and efficacy of the combination antifungal therapy to treat IFIs. Methods In this retrospective study, medical records were retrieved for patients admitted to the Pediatric Department of Yeungnam University Hospital, Daegu, South Korea, between April 2009 and May 2013. Medical records of 22 patients were analyzed. Results Of the 22 patients studied, nine (41%) had been diagnosed with probable IFI, and 13 (59%) with possible IFI. All patients, except one, were already receiving antifungal monotherapy for the treatment of neutropenic fever. After a diagnosis of IFI was confirmed, antifungal monotherapy was replaced with combination therapy. The study's overall response rate was 90.9%, with complete responses in 86.3% of the patients. Two patients experienced a side effect of a small increase in liver enzyme levels. Conclusion Voriconazole plus caspofungin combination therapy is an effective and safe treatment for serious IFI in pediatric patients with acute leukemia.
