Background Severe valgus deformity often has bone defect and laxity of the medial ligamentous, and total knee arthroplasty in severe valgus knee is, in most cases, more challenging for surgeons. The usefulness of a computer assisted navigation system in reestablishing the mechanical axis has been well established. Hence, the interest for surgeons is how the navigation system makes the procedure of total knee arthroplasty with severe valgus knee easier. Methods From June 2006 to March 2008 in Department of Joint Surgery, Shanghai Sixth People＇s Hospital, 6 patients （7 knees） with severe valgus knee underwent total knee arthroplasty using the Stryker Navigation system, which is an active wireless and imageless system. All the patients were followed up for 12 to 18 months after surgery. The X-ray radiographs for whole limbs were obtained on all patients to determine preoperative and postoperative alignments. Results A primary, posterior stabilized prosthesis was utilized in all cases. The average preoperative overall mechanical axis of the seven knees was 19.6°±4.6° of valgus （range 16°to 29°）, and the average postoperative mechanical axis was 0.4°±0.7° （range 0.8° varus to 1.4° valgus ）. Conclusions The navigation system is a very effective and useful tool for accurate intraoperative restoration of alignment in the face of significant deformity with valgus knee. To prevent component malposition, we did not reduce the knee before solidification of bone cement but controlled alignment using the navigation system up to implantation of the final component.

对生物医学样品进行化学毒剂分析检测是禁止化学武器组织(OPCW)核查小组在毒剂指称使用调查中收集事实的方法之一。丁酰胆碱酯酶(BChE)作为有机磷毒剂在体内的作用靶点,是有机磷毒剂染毒检测的最佳生物指示物之一。利用亲和固相萃取(SPE)技术进一步发展了样品预处理方法,建立了血液样品中染毒BChE的分析方法;利用胰蛋白酶酶解方法,采用基质辅助激光解吸/电离飞行时间质谱(MALDI-TOFMS)比较了血液中BChE在沙林染毒前后的肽指纹谱变化。该方法灵敏度高、快速简便,可用于OPCW生物医学样品中毒剂暴露染毒的追溯性检测。

在对钛合金激光/等离子电弧复合焊与单一激光焊的焊缝成形进行比较的基础上,研究了激光在复合等离子电弧后主要焊接工艺参数对焊缝成形的影响。结果表明,随激光功率增大和焊接速度降低,复合焊与单一激光焊焊缝的横截面形貌均由钉形向近X形转变。与单一激光焊相比,复合焊焊缝的余高和咬边较大。激光/等离子电弧“协同效应”随激光功率和焊接速度变化而不同,从而影响复合焊焊缝的熔宽和熔宽比。随焊接电流从零增大到60 A,焊缝熔宽略有增大,而焊缝熔宽比基本保持不变。

制备了Au-core@4-巯基苯甲酸@Ag-shell核壳型纳米颗粒,结合波谱形变定量分析理论,采用表面增强拉曼光谱(SERS)定量分析了尿液和红细胞样本中6-硫鸟嘌呤(6-TG)。实验结果表明,核壳型纳米颗粒和波谱形变定量分析理论相结合可以有效消除SERS增强基底表面的"热点"数目及其分布等因素的变化对SERS信号的乘子效应影响,从而实现尿液和红细胞样本中6-TG的灵敏、准确定量分析。本方法对6-TG的检出限(3σ)和定量限(10σ)分别为1 nmol/L和3 nmol/L,加标回收率在95.6%～106.7%之间。相较于传统的6-TG分析方法(如高效液相色谱法),本方法具有简单、灵敏、快速等优点,为复杂体系中6-TG的常规定量分析提供了参考。
