[Clinical characteristics and genetic analysis of a child with Neutral lipid storage disease with myopathy].

Objective: To explore the clinical phenotype and genetic basis of a child with Neutral lipid storage disease with myopathy (NLSDM).

Methods: A child who was admitted to the First Affiliated Hospital of Zhengzhou University in February 2021 for a history of elevated creatine kinase (CK) for over 2 months was selected as the study subject. Clinical and laboratory examinations were carried out, and the child was subjected to whole exome sequencing.

Secondary hemophagocytic lymphohistiocytosis in pediatric patients with visceral leishmaniasis and Epstein-Barr virus infection.

Visceral leishmaniasis-associated hemophagocytic lymphohistiocytosis (VL-HLH) is indistinguishable from those of HLH of other etiologies due to the overlap symptoms, posing a serious threat to life. In this study, we aimed to provide insights for early diagnosis and improve outcomes in pediatric patients with VL-HLH. We retrospectively analyzed the clinical and laboratory data of 10 pediatric patients with VL-HLH and 58 pediatric patients with Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis (EBV-HLH).

TET1-mediated microRNA-188-5p promoter hydroxymethylation regulates PTEN/PI3K/AKT signaling pathway in acute myeloid leukemia cells.

Objective: Acute myeloid leukemia (AML) remains a common hematopoietic malignancy, and drug resistance greatly blunts the efficacy of chemotherapy in AML treatment. Adriamycin (ADM, also called doxorubicin), is one of the most widely used chemotherapeutics for treating cancers. Herein, we studied the molecular mechanisms underlying microRNA-188-5p (miR-188-5p)-mediated ADM resistance in AML.
