Primary atypical teratoid/rhabdoid tumor of central nervous system in children: a clinicopathological analysis and review of literature in China.

Atypical teratoid/rhabdoid tumor (AT/RT) is a very rare and highly malignant embryonal tumor in the central nervous system (CNS). Five patients (4 girls and 1 boy) with AT/RT were treated in our hospital. The clinical histories, symptoms, neuroimaging aspects, therapies, histological and immunohistochemical findings and follow-up information were reviewed.

Genetic polymorphisms and serum levels of mannose-binding lectin in Chinese pediatric patients with common infectious diseases.

Background: Mannose-binding lectin (MBL) is a collagen-like serum protein that plays an important role in first-line host defense, especially in infants and young children. The objective of this study was to explore the genetic polymorphisms and serum protein levels of MBL in Chinese pediatric patients with common infectious diseases, including recurrent respiratory infection (RRI), acute respiratory infection (ARI), active cytomegalovirus (CMV) infection, localized abscess, and otitis media.

Methods: MBL genetic polymorphisms of 151 pediatric patients with infectious diseases and 105 healthy controls were detected by PCR and sequencing.
