Epigenetic priming with decitabine followed by low dose idarubicin and cytarabine in acute myeloid leukemia evolving from myelodysplastic syndromes and higher-risk myelodysplastic syndromes: a prospective multicenter single-arm trial

Patients with acute myeloid leukemia (AML) evolving from myelodysplastic syndrome (MDS) or higher-risk MDS have limited treatment options and poor prognosis. Our previous single-center study of decitabine followed by low dose idarubicin and cytarabine (D-IA) in patients with myeloid neoplasms showed promising primary results. We therefore conducted a multicenter study of D-IA regimen in AML evolving from MDS and higher-risk MDS. Patients with AML evolving from MDS or refractory anemia with excess blasts type 2 (RAEB-2) (based on the 2008 WHO classification) were included. The D-IA regimen (decitabine, 20 mg/m² daily, days 1 to 3; idarubicin, 6 mg/m² daily, days 4 to 6; cytarabine 25 mg/m² every 12 hours, days 4 to 8; granulocyte colony stimulating factor [G-CSF], 5 μg/kg, from day 4 until neutrophil count increased to 1.0 × 10⁹/L) was administered as induction chemotherapy. Seventy-one patients were enrolled and treated, among whom 44 (62.0%) had AML evolving from MDS and 27 (38.0%) had RAEB-2. Twenty-eight (63.6%) AML patients achieved complete remission (CR) or complete remission with incomplete blood count recovery (CRi): 14 (31.8%) patients had CR and 14 (31.8%) had CRi. Six (22.2%) MDS patients had CR and 15 (55.6%) had marrow complete remission. The median overall survival (OS) was 22.4 months for the entire group, with a median OS of 24.2 months for AML and 20.0 months for MDS subgroup. No early death occurred. In conclusion, the D-IA regimen was effective and well tolerated, representing an alternative option for patients with AML evolving from MDS or MDS subtype RAEB-2.     

Special topic: Emerging role of transporters in drug interaction and delivery

To date,over 400 membrane transporters have been identified and characterized in human cells at both the molecular level and functional level.These transporters are classified into two families:ATP-binding cassette(ABC)transporters and solute carrier(SLC)transporters.They are well-recognized determinants of drug disposition and metabolism,even in the development of some diseases.Due to the biological function and tissue-specific expression,transporters play a potent role not only in drug disposition but also in drug-drug/drug-food interaction,and hold great potential to be utilized as targets for drug delivery.In 2019,we published a printed book entitled Drug Transporters(PMPH 2019;ISBN 978-7-117-28219-2)in Chinese.The content of the PMPH 2019 book included the basic transporter information and its role in diseases,drug-drug interaction,and drug delivery.However,the printed PMPH 2019 book was started in 2015.The field is growing so fast that several new emerging areas were uncovered in the book,which motivated us to propose a special issue that focuses on the latest advances of drug transporters in drug interaction and delivery.In this issue,we would like to invite several contributors to discuss the emerging findings regarding transporters and drugs.

血浆色素上皮衍生因子与初发2型糖尿病患者骨密度的相关性

目的 研究初发2型糖尿病（type 2 diabetes mellitus，T2DM）患者血浆色素上皮衍生因子（pigment epithelium-derived factor，PEDF）水平与骨密度的关系。方法 纳入50例初发T2DM患者，通过问诊及查体获取其一般临床资料，采集其空腹血，检测其临床检验指标、骨代谢指标以及血浆PEDF水平，利用双能X线测量骨密度。根据骨密度是否降低分为骨量减少组和骨量正常组，比较两组人群一般临床资料、临床检验指标、骨代谢指标、骨密度、血浆PEDF水平，利用Pearson相关分析研究血浆PEDF水平与腰1～4、股骨颈以及全髋骨密度的相关性，利用单因素以及多因素线性回归研究腰1～4、股骨颈以及全髋骨密度的独立影响因素。结果 初发T2DM患者骨量减少组较骨量正常组血浆PEDF水平更低，血浆PEDF水平与腰1～4、股骨颈、全髋骨密度正相关，血浆PEDF是初发T2DM患者骨密度的独立影响因素。结论 PEDF可能作为初发T2DM患者骨密度变化的重要分子发挥作用，其有望成为治疗糖尿病性骨质疏松的新因子。     

Meeting 24-h Movement Guidelines is Related to Better Academic Achievement: Findings from the YRBS 2019 Cycle

This research is designed to investigate the relationship between the 24-h movement guidelines (24-HMG) and self-reported academic achievement (AA) using nationally representative data derived from the 2019 U.S. National Youth Risk Behaviour Survey. A multiple-stage cluster sampling procedure has been adopted to ensure a representative sample (N = 9127 adolescents; mean age = 15.7 years old; male% = 49.8%). Logistic regression has been adopted to obtain the odds ratio (OR) regarding the associations between adherence to 24-HMG and AA while controlling for ethnicity, body mass index, sex and age. The prevalence of meeting the 24-h movement guidelines in isolation and combination varied greatly (physical activity = 23.3%, screen time = 32.5%, sleep = 22.3%, and 24-HMG = 2.8%), while the percentage of highest-class AA was 42.5%. Compared with the situation when none of 24-HMG is met, the achievement of any of the combined guidelines (except for meeting the physical activity guidelines) was significantly associated with higher odds of achieving first-class AA. Meeting the sleep guideline had 1.42 times increased likelihood to achieve highest-class AA as compared with not meeting the sleep guideline. Meeting screen time guidelines and physical activity guidelines, respectively, were 1.32 and 1.13 times more likely to report first-class AA; but meeting the guidelines of physical activity was not significantly related to AA. Meeting the 24-HMG had the highest odds of achieving first-class AA (OR = 2.01, 95%CI: 1.47– 2.73). In both sexes, adolescents who met 24-HMG self-reported better AA (boys OR = 2.05, 95%CI: 1.34–3.15; girls OR = 2.26, 95%CI: 1.36–3.76). Significant relationships were observed in adolescents from 9–10th grade, but not higher grades.
