Preparation methods and research progress of super-hydrophobic anti-icing surface.

The problem of surface icing poses a serious threat to people's economy and safety, especially in the fields of aerospace, wind power generation and circuit transmission. Super-hydrophobic has excellent anti-icing performance, so it has been widely studied. As the most promising anti-icing technology, superhydrophobic anti-icing surface should not only be simple to prepare, but also have excellent comprehensive performance, which can meet the anti-icing task under harsh working conditions and long-term durability.

A Heterologous Fibrin Glue Enhances the Closure Effect of Surgical Suture on the Repair of Annulus Fibrous Defect in a Sheep Model.

Improving the closure effect of surgical suture for repair of annulus fibrosus defects remains an unsolved problem. A new type of porcine fibrin glue was reported for the repair of annulus fibrous defects in sheep models in this study. Continuous axial loading test showed that this glue could effectively improve the closure effect of surgical suture for annulus fibrous defect.

Comparison of safety and efficiency of microendoscopic discectomy with automatic nerve retractor and with nerve hook.

This study compares the safety and efficiency of two techniques in microendoscopic discectomy (MED) for lumbar disc herniation. The two techniques are MED with automatic nerve retractor and MED with nerve hook which had been widely used for many years. The former involves a newly developed MED device which contains three parts to protect nerve roots during operation.

A comparison between nucleus pulposus-derived stem cell transplantation and nucleus pulposus cell transplantation for the treatment of intervertebral disc degeneration in a rabbit model.

Introduction: In recent years, nucleus pulposus cell (NPC) transplantation has been used to treat intervertebral disc degeneration (IDD); however, the degenerative nature of NPCs influences its effectiveness. Nucleus pulposus-derived stem cells (NPSCs), which are self-renewing, have high expansion potential and can adapt to the intervertebral disc (IVD) microenvironment and may have a better regenerative capacity, which is favourable for treating IDD. The aim of this study was to compare the effectiveness of transplantation with NPSCs and NPCs on the regeneration of the IVD in rabbit models.

[Intertransverse approach microendoscopic discectomy for far lateral lumbar disc herniation].

Objective: To explore the clinical effect of intertransverse approach microendoscopic discectomy for far lateral lumbar disc herniation.

Methods: From February 2005 to February 2010, 73 patients with far lateral lumbar disc herniation were treated with intertransverse approach microendoscopic discectomy. Their clinical data were retrospectively analyzed.

[Analysis of intraoperative complications of microendoscopic disectomy and corresponding preventive measures].

Objective: To analyze the reasons of intraoperative complications of microendoscopic disectomy (MED) and corresponding preventive measures.

Methods: From October 2001 to January 2012, the data of 851 patients with lumbar disc herniation underwent MED were retrospectively analyzed. There were 469 males and 382 females with an average age of 42.
