Efficacy of Yisui granule on myelodysplastic syndromes in SKM-1 mouse xenograft model through suppressing Wnt/β-catenin signaling pathway.

Objective: To unmask the underlying mechanisms of Yisui granule (, YSG) for the treatment of Myelodysplastic syndromes (MDS).

Methods: Our study used an SKM-1 mouse xenograft model of MDS to explore the anti-tumor potential of YSG and its safety, assess its effect on overall survival (OS), and evaluate whether its mechanism is associated with the demethylation of the secreted frizzled related protein 5 (sFRP5) gene and suppressing Wnt/β-catenin pathway. Bisulfite amplicon sequencing was applied to detect the level of methylation of the sFRP5 gene; western blotting, immunofluorescence staining, and real-time Polymerase Chain Reaction were performed to detect DNA methyltransferase 1 (DNMT1), sFRP5, and other Wnt/β-catenin pathway-related mRNA and protein expression.

Improvement of Early Death in Acute Promyelocytic Leukemia: A Population-Based Analysis.

Background: Early death is a major factor of treatment failure in acute promyelocytic leukemia (APL), however, the recent trends in the incidence of early death based on the population-level are not clear. Hence, this study is aimed at describing the incidence, recent trends, causes and characteristics of early death in APL based on the real world.

Materials And Methods: APL patients diagnosed from 1986 to 2015 in the Surveillance, Epidemiology, and End Results (SEER) dataset were enrolled, and categorized based on gender, age, year of diagnosis, race, marital status, resident county and socioeconomic status (SES).

Prospective: Evolution of Chinese Medicine to Treat COVID-19 Patients in China.

During the outbreak of the novel coronavirus disease (COVID-19), the Chinese government took a series of public health measures to tackle the outbreak and recommended six traditional Chinese medicine (TCM) evolved formulas, collectively referred to as "3-drugs-3-formulas", for the treatment. In this prospective article, we will discuss how these six formulas evolved from TCM and what their underlying mechanisms of actions may be by evaluating the historical usage of the component formulas, the potential targeted pathways for the individual herbs used by STAR (signal transduction activity response) database from our laboratory, and the pathogenesis of COVID-19. Five of the six recommended formulas are administered orally, while the sixth is taken as an injection.
