Objective To observe the therapeutic effect of Shengxuenin(SXN) in treating iron deficiency anemia (IDA).Methods 60 cases with IDA from January 2007 to June 2008 were treated with SXN,2 pellets Tid per os for 30 days.The value of erythlrocyte count (RBC),haematoglobin(Hb),hematocrit(HCT),mean corpuscular volume(MCV).mean corpuscular haematoglobin (MCH),mean corpuscular-hemoglobin concentration (MHCH),Reticulocyte(Ret) was observed at the first week,the second week,the third week and the fourth week of the treatment.Results Reficulocyte count started to increase at the lst week and haematoglobin count started to increase at the 2nd week.Haematoglobin,mean corpuscular volume,mean corpuscular haematoglobin and mean corpuscular-hemoglobin concentration returned to normal at the 4th week.The gastrointestinal side effects of this thempy were fewer than treated with other chalybeate medicines.Conclusion SXN was effective in the treatment of IDA and had little gastrointestinal side effects.

OBJECTIVE: To delineate the clinical and molecular characteristics of a patient with myeloid neoplasm and co-existence of t(7;11)(p15;p15) and t(5;12)(q33;p13) translocations. METHODS: Clinical data of the patient was collected. Conventional karyotyping, reverse transcriptase (RT)-PCR and next generation sequencing (NGS) were carried out to delineate its genetic features. RESULTS: The patient has featured recurrent rash, fatigue, loss of appetite and splenomegaly. Laboratory test suggested hyperleukocytosis of FAB-M2-subtype. Neither eosinophilia nor basophilia was presented. NUP98/HOXA9 and ETV6/PDGFRB fusion genes were detected by RT-PCR. NGS and DNA-PCR showed the co-existence of WT1 p.C423Y, KRAS p.G12D and DNMT3A p.R882C mutations. The patient achieved morphological remission after imatinib plus coventional chemotherapy (standard IAC regimen). However, the disease has relapsed shortly after. Treatment was switched to HHT-Ara-C-Acla regimen, no hematological response was observed. The ETV6/PDGFRB fusion gene was undetectable in bone marrow sample, though strong expression of NUP98/HOXA9 was detectable throughout the whole course. CONCLUSION Acute myeloid leukemia in association with the co-existence of NUP98/HOXA9 and ETV6/PDGFRB fusion genes have unique clinical and genetic features. Imatinib seems to have no impact on the overall survival in such cases.

OBJECTIVE: To characterize the mutational profile of patients with core-binding factor acute myeloid leukemia (CBF-AML). METHODS: A total of 81 acute myeloid leukemia patients were recruited, which included 36 cases of CBF-AML and 45 cases of cytogenetically normal acute myeloid leukemia (CN-AML) . Mutations of FLT3-ITD, FLT3-TKD, NPM1, c-KIT, NRAS, KRAS, TET2, IDH1/2, RUNX1, DNMT3A, GATA2, ASjXL1, TP53, PTPN11, JAK2V617F, SETBP1 and CEBPA genes were simultaneously detected by DNA-based PCR and Sanger sequencing. RESULTS: Over all, mutations were detected in 68 patients (83.9%), with the most common ones including double CEBPA mutations (n=17), followed by NPM1 (n=15), c-KIT (n=11), NRAS (n=10), TET2 (n=9), FLT3-TKD (n=9), FLT3-ITD (n=8), IDH1 (n=7), RUNX1 (n=7), KRAS (n=7), DNMT3A (n=6), IDH2 (n=4), and GATA2 (n=4) mutations. AML1-ETO and CBFβ-MYH11 fusions were present in 21 and 15 patients, respectively. Coexistence of ≥2 mutations was more common in CN-AML comparing with CBF-AML. The mutation rate of NPM1, FLT3-ITD, DNMT3A, IDH1 and CEBPA double mutations were higher in patients with CN-AML. NRAS, c-KIT and KRAS mutations were identified more frequently in patients with CBF-AML (P<0.05). Based on the function, aberration of genes involved in DNA methylation, NPM1 proteins and transcription predominated in CN-AML, while tyrosine kinase receptor signaling and RAS pathways have predominated in CBF-AML. CONCLUSION The genomic landscape of CBF-AML patients has differed from that of CN-AML patients. Synergy of fusion genes with particular mutations may impact the clinical phenotype and prognosis of patients.

OBJECTIVE: To characterize the molecular genetics of 81 patients with acute monocytic leukemia (AML). METHODS: Fluorescence in situ hybridization (FISH) was employed to detect MLL gene rearrangements. Combined mutations of 17 genes were detected by DNA-based PCR and Sanger sequencing. RESULTS: Sixty seven patients were found to harbor at least one mutation. The most commonly mutated gene was NPM1 (n=18), which was followed by FLT3-ITD (n=16), NRAS (n=16), DNMT3A (n=15), TET2 (n=12), RUNX1 (n=11) and KRAS (n=9). Based on the functions of mutated genes, the most frequently involved genes were those involved in DNA methylation (38.27%), tyrosine kinase receptor signaling (32.1%), transcription regulation (28.4%), and RAS pathway (24.7%). Single gene mutation predominated in patient with cytogenetic abnormalities, while coexistence of 2 mutations have predominated in patient with normal cytogenetic findings. Stratified by cytogenetic findings, patients with single gene mutations (intermediate-risk group) had significantly higher complete remission (CR) rates than those with ≥2 gene mutations (unfavorable-risk group) (91.7% vs. 57.6% , 87.5% vs. 25.0%, P =0.0319, 0.0117, respectively). CONCLUSION Over 80% of AML patients were found to harbor at least one mutation. Their clinical phenotype and prognosis may be impacted by the synergy of MLL gene rearrangement and multiple mutations. For patients under the same risk stratification, the number of mutations is reversely correlated with the CR rate.

Objective: To carry out mutation analysis for patients with myelodysplastic syndromes (MDS) and a normal karyotype. Methods: Targeted capture and next-generation sequencing (NGS) was carried out using a customized 49-gene panel. FLT3 internal tandem duplication (FLT3-ITD), CALR, NPM1 and CEBPA mutations were detected by PCR and Sanger sequencing. Results: Sixty two patients (80.5%) were found to harbor at least one mutation. Each patient has carried 2.21 mutations in average. Coexistence of ≥ 3 mutations was common (43.7%). The most commonly mutated genes were RUNX1 (23.4%, 18/77), ASXL1 (18.2%, 14/77), NPM1 (15.6%, 12/77), U2AF1 (15.6%, 12/77), DNMT3A (11.7%, 9/77). Patients with SF3B1 mutations were significantly older than those with ASXL1 mutations (P=0.023). Mutations of the DNMT3A gene were significantly associated with the blood platelet level compared with BCOR mutations (P=0.02). No significant difference was found in the number and rate of mutations between those under or above 60-year-old. Among 67 patients with clinical follow-up, 20 (29.8%) has transformed to acute myeloid leukemia, and the time of transformation has ranged from 1 to 44 months, with a average of 5.3 months. RUNX1, U2AF1 and FLT3 mutations are associated with leukemic transformation. Conclusion Coexistence of ≥ 3 mutations are frequent among patients with normal-karyotype MDS. Certain mutations are associated with age and leukemic transformation.
