Backgrounds: Transforaminal percutaneous endoscopic discectomy (TF-PELD) and interlaminar percutaneous endoscopic discectomy (IL-PELD) are the most common alternative treatments of lumbar disc herniation. The aim of this study was to compare the operation time duration and X-ray exposure as well as outcomes of TF-PELD and IL-PELD as indicated by the published clinical evidences within randomized trials.
Methods: We included randomized, controlled studies reporting operation duration and X-ray exposure as well as clinical outcome evaluations, comparing TF-PELD to IL-PELD with a minimum of 10 patients per group.
Introduction: Nontraumatic posterior atlantooccipital dislocation has only been rarely reported. In the current study, the authors reported an extremely rare case of nontraumatic posterior atlantooccipital dislocation associated with atlantoaxial instability.
Materials And Methods: A 47-year-old female was referred with a history of neck pain for 5 years.
We report enhanced force detection selectivity based on Coulombic interactions through AFM tip modification for probing fine structures of the electric double layer (EDL) in ionic liquids. When AFM tips anchored with alkylthiol molecular layers having end groups with different charge states (e.g.

Methods: The effect of the total flavones of Chrysanthemum indicum on the proliferation of human osteosarcoma Saos-2 cells was detected by CCK assay, and the morphological changes of cells treated with total flavones of Chrysanthemum indicum were observed using contrast microscope. Flow cytomerty was performed to analyze the apoptotic rate of the cells, and the gene expression levels of Caspase-3, BCL-2, BAX were detected by RT-PCR.
