背景:脱垂游离型腰椎间盘突出症中突出游离于椎管内的髓核呈条索状、团块状,压迫神经根和硬膜囊,造成机体出现严重的腰腿痛和/或马尾神经损伤症状。目的:比较通道下单纯髓核摘除与通道辅助下微创经椎间孔椎体间融合并自体骨粒填塞治疗脱垂游离型腰椎间盘突出症的临床效果。方法:一项在2012年1月至2014年1月进行的回顾性研究,将收集脱垂游离型椎间盘突出症经保守治疗无效的58例患者,按照治疗方法分为通道下单纯髓核摘除组(n=36,仅进行单纯髓核摘除)和微创经椎间孔椎体间融合并自体骨粒填塞组(n=22,Concorde脊柱微创椎间融合器进行植骨融合,合并自体骨粒填塞)。结果与结论:2组患者术后1周、3个月及18个月时目测类比评分和Oswestry功能障碍指数均比术前明显下降(P0.05);通道下单纯髓核摘除组有2例术后复发。结果提示通道下单纯髓核摘除和微创经椎间孔椎体间融合并自体骨粒填塞治疗脱垂游离型腰椎间盘突出症均可取得满意的临床疗效,且微创经椎间孔椎体间融合并自体骨粒填塞在腰痛缓解方面更具有优势。

Although guided image filtering(GIF) is known for preserving edges and fast computation, it may produce inaccurate outputs in depth map restoration. In this paper, a novel confidence-weighted GIF called mutual-structure weighted GIF(MSWGIF) is proposed, which replaces the mean filtering strategy in GIF during handling overlapping windows. The confidence value is composed of a depth term and a mutual-structure term, where the depth term is utilized to protect the edges of the output, and the mutual-structure term helps to select accurate windows during the structure characteristics of the guidance image are transferred to the output. Experimental results show that MSWGIF reduces the root mean square error(RMSE) by an average of 12.37%, and the average growth rate of correlation(CORR) is 0.07% on average. Additionally, the average growth rate of structure similarity index measure(SSIM) is 0.34%.

Vortex transmutation utilizes a periodic system, which not only enables the alteration of the topological charge(TC) of unstable input vortices but also facilitates their transformation into stable structures. This approach is crucial for investigating the characteristics of vortices in various wave systems. Here, we achieve acoustic vortex TC transmutation by employing a welldesigned dual-structured plate external system(DPES). The interactions between the acoustic vortex and the finite-order discrete rotational symmetry lead to the transformation of its topological charge when complete rotational symmetry is broken to Nthorder discrete symmetry. Our results experimentally demonstrate the acoustic vortex TC transmutation based on passive artificial structures, enabling numerous applications in particle manipulation and information multiplexing as well as advancing our understanding and control over free-space acoustic vortices.
