Objective: To date, there is no standard diagnostic practice to identify the underlying disease-causing mechanism for paediatric patients suffering from chronic fever without any specific diagnosis, which is one of the leading causes of death in paediatric patients. Therefore, we aimed this retrospective study to analyse medical records of paediatric patients with fever of unknown origin (FUO) to provide a preliminary basis for improving the diagnostic categories and facilitate the treatment outcomes.

Design: A retrospective study.

Background: Few data on recurrent bacterial meningitis (RBM) in children are available. Here, we estimated the frequency of RBM in children and investigated the predisposing conditions, etiology, and clinical characteristics of RBM in children.

Methods: Cases of RBM in the Beijing Children's Hospital medical record database between January 2006 and December 2019 were collected.

We have previously shown that compound-7g inhibits colorectal cancer cell proliferation and survival by inducing cell cycle arrest and PI3K/AKT/mTOR pathway blockage. However, whether it has the ability to exert antitumor activity in other cancer cells and what is the exact molecular mechanism for its antiproliferation effect remained to be determined. In the present study, compound-7g exhibited strong activity in suppressing proliferation and growth of glioblastoma cells.

Objective: To study the clinical value of cranial magnetic resonance imaging (MRI) in the diagnosis and treatment of central nervous system candidiasis (CNSC), which has no specific clinical manifestations and has no rapid and specific diagnostic tools.

Methods: A retrospective analysis was performed on the clinical data of 10 children who were diagnosed with CNSC in Beijing Children's Hospital Affiliated to Capital Medical University between 2009 and 2013.

Results: Nine of the 10 children underwent cranial MRI within 8 days after admission, and 5 of the 9 children underwent contrast-enhanced MRI at the same time.
