Abstract

To observe the therapeutic effect of butorphanol on brain tissue injury in rats with sepsis through the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathway. Sprague-Dawley rats were divided into control group (n=20), sepsis model group [cecal ligation and perforation (CLP) group, n=20], and butorphanol treatment group (n=20). After successful modeling, the blood and brain tissues were collected from rats at 24 h. The content of serum brain injury indexes was detected. Hematoxylin-eosin (HE) staining assay and enzyme-linked immunosorbent assay (ELISA) were separately carried out to observe the pathological changes and measure the levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and myeloperoxidase (MPO) activity. The neurological function was scored in rats. Glial fibrillary acidic protein (GFAP), S100, and NF-κB signaling pathway genes and proteins in brain tissues were detected via quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR) and Western blotting. CLP group showed remarkably increased levels of serum glucosuria (GLU), creatinine (CR), and Na+ but an evidently reduced level of K+ in comparison with the control group (p<0.05), while the treatment group disp...Continue Reading
