Identification of the association between rs41274221 polymorphism in the seed sequence of microRNA-25 and the risk of neonate sepsis.

Background: Many studies have investigated the role of microRNA-25 (miR-25) in the initiation and progression of sepsis in newborns. In this study, we aim to explore how rs41274221 polymorphism in miR-25 compromises the interaction between miR-25 and CD69, so as to understand the mechanisms involved in the control of sepsis in newborns.

Methods: Computational analysis, luciferase assay, real-time polymerase chain reaction (PCR), and western blot analysis were performed in this study.

Association between indel polymorphism (rs145204276) in the promoter region of lncRNA GAS5 and the risk of febrile convulsion.

Background: This study aimed to explore the regulatory relationship between growth arrest special 5 (GAS5) and interleukin-1β (IL-1β) implicated in the development of febrile seizure (FS).

Method: The presence of FS and the genotype of GAS5 were used as two different indicators to divide the 50 newborn babies, recruited in this study, into different groups. The potential regulatory relationship among GAS5, miR-21, and IL-1β was identified by measuring their expression using quantitative reverse-transcription polymerase chain reaction and immunohistochemistry assays among different sample groups.

Differentiation expression of toll-like receptor4 (TLR4) caused by the dysregulation of microRNA-140-5p is responsible for the development of postoperation infection.

Background: Toll-like receptor4 (TLR4) has proven to be an important factor that's responsible for the development of postoperation infection. MicroRNAs (miRNAs) are widely regarded as key mediators of gene expression. The objectives of our study were to identify miRNA(s) and the target genes differentially expressed in monocytes in the individuals with postoperation infection.

Effects of vitamin D on apoptosis of T-lymphocyte subsets in neonatal sepsis.

Effect of vitamin D on apoptosis of peripheral blood T-lymphocyte subsets in treatment of neonatal sepsis was investigated. A total of 150 neonatal patients with sepsis were randomly divided into vitamin D treatment group (observation group) and treatment control group, while 100 healthy newborns were selected as healthy control group. T-lymphocyte subsets were detected by flow cytometer, the levels of tumor necrosis factor-α, interleukin-1 and calcitonin were determined by double-antibody immunoluminometric assay, and the effect of vitamin D on the above indicators in the treatment of sepsis was observed.
