Objective@#To analyze the prognostic value of CD7 expression in newly diagnosed acute myeloid leukemia (AML) patients, and to further explore the correlation between CD7 expression and CEBPA mutation, and to clarify the prognostic value of CD7+ in AML patients with wild-type (WT) or mutant-type (MT) CEBPA.@*Methods@#The clinical data of 298 newly diagnosed non-M3 AML patients between January 2010 and December 2016 were analyzed retrospectively. The clinical characteristics and prognosis of CD7+ and CD7- patients were respectively compared in all patients, and in patients with WT and MT CEBPA. The relationship between CD7 expression and CEBPA mutation was determined by chi-square, and the effects of CEBPA mutation on survival and prognosis in CD7+ group by Kaplan-Meier method.@*Results@#In CD7+ group, the frequencies of CEBPA mutation were 10.1% (single site) and 33.9% (double site) , significantly higher than those of the CD7- group (5.3% and 4.2%) (P=0.000) . Subgroup prognostic analysis showed a lower CR rate (P=0.001) and a higher RR (P=0.023) in CD7+ group comparing to those of CD7- group in AML patients with wild type CEBPA. There were no statistical difference between CD7+ group and CD7- group in overall survival (OS) and disease free survival (P>0.05) , while in the CEBPA mutant group the CD7+ group has higher OS (P=0.019) and DFS (P=0.010) . Based on the CD7 expression and CEBPA mutation, 298 cases were divided into 3 subgroups, named as CD7+-CEBPA MT group, CD7- and CD7+-CEBPA WT group. The 3-year OS of the 3 groups were 80.2%, 48.0% and 30.6%, respectively (P<0.001) , and the 3-year DFS were 74.1%, 37.4% and 22.2%, respectively (P<0.001) .@*Conclusion@#The CEBPA mutation rate was higher in CD7+ AML patients then that of CD7- patients. CD7 expression has opposite prognostic significance in AML patients carrying the wild-type or mutant-type CEBPA. Based on CD7 expression and CEBPA mutation, a new risk stratification model can be established, which is helpful to guide the clinical individualized treatment for AML patients.

Aberrant DNA methylation and its targeted therapy in acute myeloid leukemia / 浙江大学学报·医学版

The occurrence and development of acute myeloid leukemia (AML) is not only related to gene mutations, but also influenced by abnormal epigenetic regulation, in which DNA methylation is one of the most important mechanisms. Abnormal DNA methylation may lead to the activation of oncogene and the inactivation of tumor suppressor gene, resulting in the occurrence of leukemia. The mutations of DNA methylation enzymes associated with AML may have certain characteristics. The AML with recurrent cytogenetic abnormalities is also related to abnormal methylation. Some fusion genes can alter DNA methylation status to participate in the pathogenesis of leukemia. In addition, chemotherapy drug resistance in patients with AML is associated with the change of gene methylation status. Considering the reversibility of the epigenetic modification, targeted methylation therapy has become a hotspot of AML research.

Short-term effects of hemogram in healthy donors after peripheral blood stem cell collection / 中华血液学杂志

<p><b>OBJECTIVE</b>To observe the short- term effects of hemogram in donors after peripheral blood stem cell（PBSC）collection and donors' tolerance.</p><p><b>METHODS</b>A total of 166 related allogeneic donors were selected from The First Affiliated Hospital of Medical School of Zhejiang University between January 2013 and December 2014, including 86 male and 80 female. All donors accepted granulocytecolony- stimulating factor（G-CSF）5-10 μg·kg⁻¹·d⁻¹ until collection finished and were measured by blood cells count before and after PBSC collection.</p><p><b>RESULTS</b>After PBSC collection, the hemoglobin level decreased from 145（94-181）g/L to 138（93-167）g/L, and the platelet counts decreased in all donors from 231（105- 490）× 10⁹/L to 95（39- 210）× 10⁹/L. The amount of hemoglobin contamination in collection products was weak correlated with the decreased hemoglobin in peripheral blood（r=0.297, P=0.017）, and the platelet contamination was high correlated with that decreased in peripheral blood（r=0.719, P<0.001）. The decline of hemoglobin level after twice PBSC collection was of no significant difference between four groups in different ages（P≥0.05）. The decline of platelet counts was out of a significant difference（P> 0.05）. In addition, the decline of hemoglobin level after once and twice PBSC collection was of a significant difference between four groups in different body mass index（BMI）（P=0.003 and P<0.001）, especially in thinner group with obvious decrease. But the decline of platelet counts was out of a significant difference （P>0.05）.</p><p><b>CONCLUSION</b>The hemoglobin level decreased mildly in healthy allogeneic hematopoietic stem cell donors after PBSC collection and it is better to adjust parameters every time to ensure their safety for thinner donors. However, it will increase the risk of platelet decline, which is unrelated with ages and BMI and can be tolerated.</p>

A MICROELECTROPHORETIC DELIVERY OF HORSERADISH PEROXIDASE FOR DEMONSTRATING THE AFFERENT PROJECTION TO NUCLEUS RAPHE MAGNUS / 解剖学报

20 adult healthy rats were used for microelectropheretic delivery of horseradish peroxidase (HRP). The diameter of the tip of the glass electrode was around 20～50?. It was inserted into nucleus raphe magnus, 20% HRP was delivered microelectrophoretically(5 ?A for 30 min; 10 ?A for 10 min). In eight rats the microelectrode was withdrawn immediately after the delivery and in the rest it was removed 10～20 minutes after delivery. Afterward the animals were allowed to survive for 40 hrs before decapitation, except 2 for 20 and 2 for 60 hrs. The brains were dissected out for cryostat sections and DAB reaction for peroxidase.The tip of the electrode was located in the nucleus raphe magnus, at the level of nucleus facialis. The diameter of the brain tissues occupied by HRP at the points of microelectophoretic delivery was 0.2～0.4mm and the maximum reached 0.6～0.7mm. The exogenous HRP granules were not visible in the cases with electrodes withdrawn immeditely after delivery and in the survivors of 60 hrs. In most cases the electrodes were left inside for more than 10 minutes after the delivery. The exogenous HRP granules were large, coarse, brown, steroscopic and distributed evenly in the perikaryon of some neurons in several levels of the brain. Those in the axon and dentrite were distributed just like strings of pearls. There were much more neurons with exogenous HRP positive granules dispersed in the reticular formation of the medula oblongata, most of them were polydendritic. Small and fusiformed HRP-positive cells are observed occasionally in the gray substance of subventriculum, reticular formation pontis and ventrolateral side of locus coeruleus. Weaker reactions were found in a few cells in the periaquaductous gray substance of the midbrain, nucleus raphe centro-superior, substantia nigra pars compacta and in the area around the nucleus supraopticus. Besides no HRP-positive cells were discovered in thalamus and subcortex structure.There were two types of cells with HRP positive granules around some blood vessels in reticular formation and subventricular gray substance: One was a small protoplasmic astrocyte with broad cytoplasma, small nucleus, and thick, short and irregular processes and another kind was polydendritic neurons filling with brown positive granules in perikarya and cytoprocesses, in the latter, the HRP positive granules were arranged as strips of pearls.
