Objective: Previous studies reported that the location of the center of rotation (COR) at instrumented level after cervical total disc replacement (TDR) deviated from its preoperative location.However, currently, it is unknown whether the deviated COR is linked to the range of motion (ROM) at instrumented level.The purpose of this study was to evaluate the clinical outcomes after cervical TDR with ProDisc-C and investigate the location change of the COR at instrumented level and its clinical significance.Methods: A total of 23 patients who underwent single-level cervical TDR with ProDisc-C were included.Japanese Orthopaedic Association (JOA) score and Neck Disability Index (NDI) were used to assess clinical outcomes.Radiographic parameters such as cervical ROM, instrumented segmental ROM, adjacent segmental ROM and intervertebral height were analyzed.

目的 胎盘因素可能在子痫前期(PE)的发病中起到中心或者启动作用.滋养细胞作为胎盘的主要细胞类型,具有分化、增殖、侵袭和迁移的能力.滋养细胞的侵袭性主要依赖于细胞粘附分子(如E-cadherin)等,研究表明滋养细胞侵袭不足和子宫螺旋动脉重铸不完全与PE 的发病相关.本研究通过应用胎盘绒毛滋养细胞(VCT)和绒毛外滋养细胞(EVCT)组织芯片检测PE 患者E-cadherin的表达水平,探讨E-c
阻塞性黄疸(obstructive jaundice,OJ)是由胆道阻塞引起胆汁排谢障碍的一种病理现象.胆汁酸(bile acids,BAs)是胆固醇经肝脏作用生成的一种代谢产物.胆道阻塞时,BAs 无法经胆道排泄,而是逆流进入血液循环,引起血清总胆汁酸(total bile acid,TBA)升高.
