OBJECTIVE: To investigate the role of satellite glial cells in irritable bowel syndrome(IBS) and the effect of electroacupuncture(EA) at the Tianshu(ST25) and Shangjuxu(ST37) combination. METHODS: A model for visceral hypersensitivity in IBS was induced through colorectal distension(CRD) stimulation. Clean-grade male Sprague-Dawley(SD) rats were randomly divided into four groups: a normal group(NG), a model group(MG), an electroacupuncture group(EA), and a glial cell inhibitor group(FCA). Bilateral EA(2/100 Hz, 1 mA, 30 min) was administered at the Tianshu(ST25) and Shangjuxu(ST37) in week 6. Abdominal withdrawal reflex(AWR) scores were used to assess the behavioral response associated with visceral hyperalgesia, while hematoxylin-eosin staining was employed to evaluate pathological changes in the colon. The protein and mRNA levels of glial fibrillary acidic protein(GFAP) in the colon and colon-related dorsal root ganglion(DRG) were analyzed using immun-ofluorescence, immunohistochemistry, Western blotting, real-time polymerase chain reaction. The impact of EA on electrophysiological properties of colon-related DRG neurons was observed through whole-cell patch clamp analysis. RESULTS: EA significantly reduced the visceral pain behavior scores in rats with IBS in response to graded(20, 40, 60, 80 mm Hg) CRD stimulation. Additionally, EA downregulated the protein and mRNA expression levels of GFAP in the colon and colon-related DRG of rats with IBS. EA also regulated the resting membrane potential, rheobase and action potential of colon-related DRG neurons in rats with IBS. CONCLUSIONS: EA can regulate the excitatory properties of colon-related DRG neurons by downregulating the protein and mRNA expression of GFAP in the colon and colon-related DRG, indicating a potential neurobiological mechanism by which EA relieves visceral hypersensitivity in rats with IBS.

The structural transformation from a liquid into a crystalline solid is an important subject in condensed matter physics and materials science. In the present study, first-principles molecular dynamics calculations are performed to investigate the structure and properties of aluminum during the solidification which is induced by cooling and compression. In the cooling process and compression process, it is found that the icosahedral short-range order is initially enhanced and then begin to decay, the face-centered cubic short-range order eventually becomes dominant before it transforms into a crystalline solid.
