This study was aimed to investigate the expression level of NF-kappaB mRNA in acute myeloid leukemia (AML) using real time fluorescence quantitative polymerase chain reduction (qPCR) detection and to explore the effect of NF-kappaB mRNA in pathogenesis of AML. The fresh bone marrow was collected from 60 newly diagnosed patients with AML, the total RNA was extracted by means of RTIzoL, the cDNA was synthesized, the expression of NF-kappaB mRNA was detected by qPCR using GAPDH as internal reference. 12 normal healthy persons were selected as controls. The results showed that the expression of NF-kappaB mRNA in patients with AML was higher than that in normal healthy persons with significant difference (p<0.05), the expression of NF-kappaB mRNA in patients with AML-M4 and -M5 were higher than that in patients with AML-M1, -M2 and -M3. It is concluded that the expression of NF-kappaB mRNA is higher in patients with AML. The up-regulation of NF-kappaB expression in patients with AML may play an important role in pathogenesis of AML.

() is a significant pathogen associated with clinical mastitis in cattle. Anti-inflammatory drugs are necessary to alleviate pain and inflammation during clinical mastitis. Among many drugs, meloxicam (MEL) has been widely used in clinical mastitis because of its excellent inhibitory effect on the cyclooxygenase-2 (COX-2) enzyme.

Bacterial infections are prevalent and the major cause of morbidity and mortality in cirrhosis. Activation of human Kupffer cells (HKCs) from livers is essential for human innate immunity. Cytosolic phospholipase A2 (cPLA2) plays a crucial role in the control and balance of innate immune and inflammatory reactions.

Objectives: To observe the reparative effects of human umbilical cord mesenchymal stem cell (hUC-MSC) transplantation on white matter injury (WMI) in neonatal rats and explore its mechanism through the nuclear factor-kappa B (NF-κB) signaling pathway mediated by microglial cells.
Methods: Sprague-Dawley rats, aged 2 days, were randomly divided into three groups: sham-operation,WMI, and hUC-MSC (=18 each). Fourteen days after modeling, hematoxylin-eosin staining was used to observe pathological changes in the white matter, and immunofluorescence staining was used to measure the expression level of ionized calcium-binding adapter molecule 1 (Iba1).

Background: The primary purpose of this study was to demonstrate the preventive effects of imatinib (IMA) on lipopolysaccharide (LPS)-induced inflammation in a mouse model of acute lung injury (ALI) and human umbilical vascular endothelial cells.
Methods: LPS stimulation for 24h induced ALI and cell inflammation. The pathological results of the lungs were evaluated using the wet/dry weight ratio, pulmonary vascular permeability measurements, and myeloperoxidase immunohistochemistry.
