合理选择手术方式是治疗不稳定上颈椎骨折的基础,提高上颈椎螺钉置钉的准确性是减少并发症、提高疗效的关键.随着多项上颈椎骨折临床诊疗指南的发布以及多种辅助置钉技术在上颈椎骨折治疗中的应用,手术治疗不稳定上颈椎骨折的安全性和疗效取得一定进步,但仍存在不足之处,包括内固定位置不佳所致的神经血管损伤、骨折不愈合及内固定失败等,并不少见.笔者就如何合理选择上颈椎骨折手术方式以及3D打印、显微镜辅助、计算机导航和机器人辅助技术在上颈椎骨折手术中的应用进行探讨,为上颈椎骨折的治疗提供指导和帮助,同时为手术技术的创新与改进提供理论基础.

Objective:To access the clinical result of percutaneous pedicle screw fixation using Zina system in treating thoracolumbar ***:From September 2013 to February 2014,a total of 30 patients with thoracolumbar fractures(type A,loadsharing ≤ 6,without neurological deficit) underwent percutaneous pedicle screw fixation using Zina system(percutaneous group,PG) were retrospectively *** perioperative parameters,radiographic and clinical results were compared with another 30 patients underwent trans-spatium intermuscular pedicle screw fixation(trans-spatium intermuscular group,TSIG).Result:In PG,the length of skin incision was(7.35±0.76)cm,the operative time was(95.7±14.2)min,intraoperative blood loss was(53.7±19.9)ml and the VAS of postoperative first day was(3.7±1.3)point;while in TSIG,the data were(9.80±1.92)cm,(82.3±16.4)min,(122.0±28.2)ml and(5.8±1.3)point respectively,which showed significant difference between two groups(P <0.05).In PG,the anterior vertebral body height and Cobb angle at the pre-operation,post-operation and final followup were(60.8±12.1)%,(88.3±6.9)%,(86.5±7.2)%,(18.5±4.9) °,(4.9±2.5) ° and(5.2±1.7) °;While in TSIG,the data were(61.8 ±9.9)%,(91.1 ±4.3)%,(91.3 ±4.2)%,(19.0 ±3.7)°,(4.7±3.5) ° and(4.8±3.4) °,which showed significant difference between two groups(P < 0.05).Compared to at the pre-operation,the anterior vertebral body height and Cobb angle at the post-operation were corrected significantly in both groups(P < 0.05).Compared to at the post-operation,there were no significant losses of the recovery of the anterior vertebral body height and Cobb angle at the final follow-up in both groups(P < 0.05).Conclusion:Under strict control of surgical indications,percutaneous pedicle screw fixation using Zina system in treating thoracolumbar fractures is comparable to trans-spatium intermuscular pedicle screw fixation,with the advantages of shorter incision,less blood loss and less postoperative pain.

Our previous experimental result for proton-rich nucleus ^(8)B at above the Coulomb barrier shows that in spite of its low proton separation energy(0.136 MeV)there is no strong breakup coupling effects[1].The fact is in contrast to the observation of neutron-rich nuclei ^(11)Be around the Coulomb barrier.A systematic study for elastic scattering cross sections of neutron-rich nucleus ^(11)Be and the proton-halo nucleus ^(8)B at low and higher energies shows that the Coulomb rainbow in the elastic scattering of ^(11)Be is still strongly suppressed at high energies[2].In order to examine the predictions,experimental measurements for 11Be elastic scattering and breakup for ^(11)Be+^(208)Pb system at 141 and 209 MeV were performed at the National Laboratory of Heavy Ion Research of the Institute of Modern Physics,Lanzhou,China.

经关节螺钉、椎弓根螺钉、椎板螺钉和峡部螺钉固定技术是目前主要的枢椎后路内固定方法。magerl经关节螺钉固定技术是寰枢固定的经典方法,但具有较高的手术风险。椎弓根螺钉、椎板螺钉和峡部螺钉固定可以解决绝大部分临床问题,但对于一些解剖变异,如椎动脉高位骑跨畸形、椎弓根过细、椎板薄等特殊情况则可能无法应用。枢椎椎动脉畸形的发生率可高达23%,在椎动脉高跨状态下,峡部螺钉风险较高;若椎动脉高跨过于严重,则椎弓根螺钉亦无法置入;峡部螺钉的钉道距离短,把持力有限,骨质疏松等情况不适合应用。在椎弓根变异的同时可能还存在椎板薄的情况,从而导致椎板螺钉也无法使用。Cassinelli等通过对尸体枢椎标本的解剖学研究发现,29.5%的枢椎椎板厚度不宜进行螺钉固定。枢椎具有颈椎中最大的棘突,初步临床、解剖学和生物力学研究发现枢椎棘突螺钉固定具有一定的可行性。2004年Goel等首先报道了临床使用枢椎棘突螺钉固定,未出现任何并发症。枢椎棘突螺钉可以完全在直视下置钉,能避开椎动脉和脊髓,不仅具有一定的生物力学稳定性,而且操作简易,无椎动脉和脊髓损伤风险。笔者对枢椎棘突螺钉固定的研究进展综述如下。

具备个性化、精准化的3D生物打印技术构建优良生物相容性的组织工程支架,替换或修复人体中病变的组织和/或器官,在组织工程研究中极具广泛的应用前景。而作为3D打印技术的基材,如金属、生物陶瓷、高分子材料和细胞生物材料等,也因此得到了研究者的重视和研发。由金属和生物陶瓷制备的支架具有高强度和耐腐蚀性,已在骨科中得到广泛应用,而高分子材料由于其和细胞/组织的良好生物相容性及可塑性使其在软骨、矫形外科、心血管系统等组织/器官中被广泛研究。相信在不久的将来,以上述材料为基材结合3D生物打印技术构建的组织和器官,在临床上会得到应用和推广。本文就用于3D打印的生物材料及其打印技术在组织工程支架构建及组织再生中的应用进行综述。

The ＂island of inversion＂ has been known for over a quar- ter century, since Warburton et al. [1] proposed that nuclei with intruder ground states would constitute a 3x3 square with Z=10-12, N=20-22 in 1990. Uncovering the underlying inversion mechanism and exploring the scope of the island have attracted significant theoretical and experimental efforts in the following years. Now it is well known that the reduction of N=20 shell gap, which is likely caused by the strong nucleon-nucleon tensor interaction [2-5], allows the intrusion of neutron orbits from the pf shell into the sd shell and results in the inversion of the 2p-2h intruder and 0p-0h normal con- figurations of the nuclear ground states in this region. Mean- while, the original border of the ＂island of inversion＂ has been extended greatly [6-14].
