Method 144 CP patients below 10 years were successfully performed SPR at L&R under combined intravenous and inhalation anesthesia (CIIA) in prone position with threshold values of each nerve root being measured by means of nerve root electric stimulus (NRES). Result All patients were performed SPR and NRES successfully although blood pressure and heart rate increased significantly while NRES. Conclusion CIIA is safe and effective for juvenile CP patients to be performed SPR at L&R.展开更多

In order to explore the role of NIRS in the expression of IL-2Rα gene, luciferase reporter plasmids driven by 4 individually deleted IL-2Rα genes promoter regions were constructed. Transfection of the reporter plasmids into Jurkat cells and HeLa cells respectively, we found that both NIRS and NRE were critical for repressing the constitutive expression of IL-2Rα gene and were also necessary for promoter activity induced by PHA. EMSA results showed that double-stranded NRE- and NIRS-bind-ing proteins existed in both HeLa cells and Jurkat cells. However, single-stranded NIRS- and NRE-binding protein was only found in HeLa cells. Interestingly, the supershift band showed up in EMSA system with Jurkat cells (no matter whether activated or not) adding to the cell展开更多
