阻生牙是口腔中较常见的一种发育畸形,以尖牙、第三磨牙、中切牙、前磨牙及第二磨牙的阻生多见,尤以下颌第三磨牙及上颌尖牙阻生的患病率最高。目前国内外学者对阻生牙的研究主要集中在上颌尖牙和第三磨牙方面,对阻生前磨牙的研究甚少。临床上,很大一部分正畸患者需要进行拔牙矫治,且拔牙牙位主要位于前磨牙区,可见阻生前磨牙对正畸矫治设计及预后影响极大。本文对阻生前磨牙现有的研究状况进行综述,对阻生前磨牙的流行病学特点、临床定位和治疗方法进行总结,以期为正畸医生制定正畸矫治计划提供参考。.

肝内胆管细胞癌(ICC)的发病因素、地域分布、临床表现、生物学特征等存在较大异质性,发病机制尚未明确。近年来的研究发现,ICC的细胞起源呈多元化,包括肝细胞、胆管上皮细胞、管周腺体细胞和肝干细胞等,ICC的发生、发展及转移等与糖代谢、脂代谢等多种代谢密切相关。ICC的生物学特征、临床表现的异质性可能与其多元化细胞起源、多种代谢机制及途径密切相关。因此,需要深入研究ICC的细胞起源和代谢特点与临床特征和生物学特性之间相关性并进行分类。根据分类采取相应的外科及综合治疗策略,做到个体化、规范化的精细治疗,改善患者预后,延长生存时间。.

对空心侧孔椎弓根螺钉(fenestrated pedicle screw,FPS)的研发背景、生物力学特征及临床应用进行综述。. 查阅近年国内外有关FPS的文献并进行综述。. 与传统椎弓根螺钉钉道强化相比,FPS能够通过中空孔及侧边孔实现聚甲基丙烯酸甲酯(polymethyl methacrylate,PMMA)强化,术中操作更简便。强化后的FPS能够在骨质疏松椎体牢固锚定,同时能降低PMMA渗漏风险。. FPS是脊柱内固定技术的一大创新,有望提高PMMA强化椎弓根螺钉固定骨质疏松椎体的疗效。.

综述多孔钽制造工艺、理化性质、生物学特性及其在脊柱外科中的应用进展。. 查阅国内外关于多孔钽材料相关文献,并进行总结、分析。. 多孔钽具有高孔隙率、高表面摩擦系数、低弹性模量的特点,以及良好的生物相容性及骨整合能力,其制作方法主要有化学气相沉积/渗透技术、泡沫浸渍和粉末冶金技术以及热处理方法。多孔钽椎间融合器已应用于颈、腰椎融合术,但在颈椎融合率问题上仍存在较大争议。通过表面修饰可增加多孔钽骨整合能力,提高椎间融合率。. 多孔钽椎间融合器用于腰椎手术中疗效确切,而在颈椎手术中仍存在争议,有待扩大样本量、延长随访时间进一步观察。.
