A total of 3 independent variables were filtered by LASSO analysis from the 22 candidate factors. The AUC of the training and validation sets were 0.833 (95%CI 0.774-0.894) and 0.817 (95%CI 0.711-0.922), respectively, which indicated a good discrimination ability. The calibration charts showed that the prediction probability and the actual probability fitted well. The DCA of the prediction model indicated an excellent clinical efficacy.<br /><br /> The proposed nomogram can quantitatively and conveniently predict the recurrence rate of CSDH after burr hole with irrigation surgery. Besides it can facilitate customized treatment adjustment and follow-up of patients who are at a high-risk of recurrence.<br /><br />The proposed nomogram can quantitatively and conveniently predict the recurrence rate of CSDH after burr hole with irrigation surgery.

Sham rats received a sham operation by exposing the right sciatic nerve without transection, while those in the Control, U100, and U500 groups underwent right sciatic nerve transection followed by immediate primary anostomosis. Sham and Control groups received saline (0.9% NaCl) injections intraperitoneally (i.p.), while U100 and U500 groups received 100 mg/kg and 500 mg/kg uridine injections (i.p.), respectively, once a day for 7 days after the surgery. Rats in all the groups were sacrificed on the eighth day; sciatic nerve samples were analyzed for apoptosis by Western Blotting and for oxidation parameters including myeloperoxidase (MPO), malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) by Enzyme-Linked Immunosorbent Assay (ELISA).<br /><br /> Uridine treatment at the dose of 500 mg/kg significantly decreased as apoptosis determined by Caspase-3/Actin ratio and exhibited significant anti-oxidant effects as determined by decreased levels of MPO and MDA as well as increased levels of SOD, GPx, and CAT compared to controls. Uridine at 100 mg/kg was only found to decrease the Caspase-3/Actin ratio, although it significantly decreased MDA and increased CAT levels compared to controls.<br /><br /> Treatment with uridine reduces apoptosis and oxidation in a rat model of sciatic nerve injury dose-dependently. Thus, uridine may be beneficial in peripheral nerve regeneration by exhibiting anti-apoptotic and anti-oxidant effects.<br /><br />Treatment with uridine reduces apoptosis and oxidation in a rat model of sciatic nerve injury dose-dependently.

C16223T, T16189C, T16311C and T16126C variants were frequently detected. The total variation number was statistically non-significant among the analyzed categories. When individual variants were considered, T16311C and T16224C were statistically significant for WHO classification (p=0.033), morphological grade (p=0.036) and gender (p=0.039), respectively.<br /><br /> Total variation number in D-loop was not found to be related with clinical variables. Our data suggests that individual variants may play a critical role in glioma biology.<br /><br />Total variation number in D-loop was not found to be related with clinical variables.

All the cases underwent normal imaging examinations included another MRI of lumbar spine within a week postoperative. The clinical efficacy were calculated to evaluate the clinical effect of therapy by Oswestry Disability Index(ODI) and Visual Analogue Scale(VAS) at 1day pre-operation, 3 months post-operation, 1 year post-operation and the last follow-up visit.<br /><br /> All patients were followed up for above two year. 44 patients were enrolled in PETD group and 42 patients in PEID group separately. The symptoms showed evident improvement after surgery, but there were no significant differences regarding VAS scores, ODI scores, spinal canal occupation rate and lumbar lordosis except disc height and pfirrmann grade between the two groups(P 0.05). Revision surgery rates at the last follow-up point were 2.3% and 4.8% in PETD group and PEID group respectively (P=0.612).<br /><br /> Approaches of PEID and PETD are pivotal to address lumbar disc herniation (LDH) disease.

Selection of surgery approach depends on anatomical structure, physiological characteristic and operative skill of the surgeon.<br /><br /> The aim of this study was to create an alternative synthetic dural graft using a parenteral solution bag made of polyvinyl chloride/polypropylene (PVC/PP).<br /><br /> Twenty-two albino rats were divided into the Sham, DC and BAG groups. Except for the Sham group animals, the right parietal bone of the rats was totally drilled in a diameter of 1.0 x 0.5 mm. Then, the PVC/PP BAG was layered over the craniectomized bone of the BAG group animals. Thirty days later, all animals were sacrificed, and inflammatory processes consisting of polymorphonuclear cell infiltration, inflammation, edema, hyperemia, lymphocytosis, histiocytosis, vascular proliferation, and fibrosis were graded at the craniectomy site.<br /><br /> The grade values of inflammation, edema, histiocytosis, and fibrosis were found different among the groups (p 0.017). It was observed that placing a synthetic graft to the surgical site undergoing craniectomy could prevent fibrotic adhesions that might occur between the brain tissue and scalp in the chronic period. Furthermore, it was considered that this synthetic material did not increase inflammatory processes secondary to surgery at the surgical site and did not produce a foreign body reaction, toxicity, or infection.
