Objective To observe the biological characteristics and analyse primary therapeutic response of acute erythroid leukemia.Methods The data of 28 patients primarily diagnosed as acute erythroid leukemia were analyzed.The patients were divided into with muhilineage dysplasia group and without muhilineage dysplasia group,and the morphology,immunology,cytogenetics and molecular biology characteristics and the complete remission rate of the first induction therapy were compared.Results There were 14 cases(50％)with muhilineage dysplasia,which involved in two lineage or trilineage.In 6 cases by flow cytometry,the myeloid blast immunophenotypes were common expressed.In 8 cases detected by karyotype analysis,5 cases were chromosomal abnormal,including 4 cases were complex chromosomal abnormal,1 case was trisomy 8.In 4 cases underwent WT1 detection,all of them were positive.The complete remission rate of the first induction therapy was 39.29％(11/28),the ratein the multilineage dysplasia group was 35.71％(5/14),and the ratein without multilineage dysplasia group was 42.86％(6/14),the difference had no statistical significance(P＞0.05).The complete remission rate of the complex chromosome group was 25.00％(1/4),the intermediate prognostic group was 50.00％(2/4).Conclusions Acute erythroid leukemia had special biological features different from other subtype AML:accompanyed with high frequency of multilineage dysplasia.The abnormality of karyotype were high,and it was often complex karyotype involved with chromosome 5 and/or chromosome 7,which had a low complete remission rate.The complete remission rate of chemotherapy was low,treatment effect was poor.

The prevalence of prediabetes is increasing rapidly in China, and with higher prevalence in coronary heart disease and hypertension patients. Diabetes can be controlled and prevented, previous studies have confirmed that lifestyle interventions and drug interventions can delay the progression of prediabetes to diabetes, and acarbose can be used for the primary prevention of cardiovascular events in impaired glucose tolerance(IGT) and diabetic patients, but benefits of drug intervention for secondary prevention of cardiovascular disease in IGT population are uncertain. The Acarbose Cardiovascular Evaluation(ACE) Study is a multicentre, randomized, placebo-controlled, double-blind study, with the aim of assessing the use of acarbose to reduce the risk of cardiovascular events and the onset of diabetes in IGT patients with cardiovascular disease in China , the results will be very meaningful and valuable for the prevention and treatment of diabetes. We will predict the results of ACE Study based on previous evidences.
