Reduced doses of emicizumab achieve good efficacy: Results from a national-wide multicentre real-world study in China.

Introduction: Reduced doses of emicizumab improve the affordability among patients in developing countries. However, the relationship between variant dose selection and efficacy in the real world of China is still unclear.

Aim: This study aimed to investigate the efficacy and safety of emicizumab especially in those on reduced dose regimens in a real-world setting.

Early Death and Survival of Patients With Acute Promyelocytic Leukemia in ATRA Plus Arsenic Era: A Population-Based Study.

Most randomized trials for acute promyelocytic leukemia (APL) have investigated highly selected patients under idealized conditions, and the findings need to be validated in the real world. We conducted a population-based study of all APL patients in Zhejiang Province, China, with a total population of 82 million people, to assess the generalization of all-trans retinoic acid (ATRA) and arsenic as front-line treatment. The outcomes of APL patients were also analyzed.

[Clinical analysis and laboratory findings in a patient with acquired hemophilia A].

In order to analyze the clinical features and laboratory findings in patients with acquired hemophilia A, one case of acquired hemophilia A was studied, the medical history, clinical features, ultrasonography and laboratory examination including activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT) and FVIII:C, FIX:C, FXI:C, FXII:C ratio, as well as medical treatment were analyzed. The results showed 99.3 sec of APTT, 13 sec of PT, and 13.

[Hereditary hemorrhagic telangiectasia resulted from a nonsense mutation Arg479 Stop in the ALK-1 gene].

Objective: To identify the gene mutations in a pedigree with hereditary hemorrhagic telangiectasia.

Methods: Genomic DNA was extracted from the peripheral blood of the propositus. All of the exons, intron/exon boundaries and the 5' untranslation regions (UTR) of the ALK-1 and endoglin gene were amplified by polymerase chain reaction (PCR).
