Research on T Lymphocyte Subsets and NK Cells Activity in Peripheral Blood of Hypopharyngeal Squamous Cell Carcinoma

目的:分析下咽鳞状细胞癌患者外周血T淋巴细胞亚群和NK细胞活性情况,旨在为相关研究工作提供参考资料。方法:择取2011年6月-2016年5月本院收治的95例下咽鳞状细胞癌病患为病例组,另取此期间内来本院接受健康检查的72例志愿者为正常组。使用流式细胞仪对病患开展相关检查,分析病例组与正常组的淋巴细胞亚群、NK活性情况以及不同临床分期的下咽癌病患外周血T淋巴细胞亚群以及NK细胞活性之间的关系。结果:与正常组相比,病例组的NK细胞、总B淋巴细胞、总T淋巴细胞、辅助/抑制T细胞、辅助T细胞偏低(P0.05)。Ⅰ~Ⅱ期病患辅助T淋巴细胞比Ⅲ~Ⅳ期者略高(P>0.05)。Ⅰ~Ⅱ期病患抑制T淋巴细胞值比Ⅲ~Ⅳ期者低(P0.05)。Ⅰ~Ⅱ期病患外周血NK细胞数比Ⅲ~Ⅳ期者略高(P>0.05)。结论:下咽鳞状细胞癌病患的免疫功能异常,且随着疾病的进展,细胞免疫和体液免疫均有所降低,证实免疫功能紊乱在疾病进展中发挥了一定作用。经流式细胞设备对外周静脉血淋巴细胞亚群以及NK细胞活性情况检测,可实现动态化检测癌症病患某阶段细胞免疫功能变化详情,此法方便简单,在指导治疗方案制定以及监测疾病预后方面,均体现出了一定效果,值得进一步推广

Design and fabrication of uncemented femoral prosthesis using CAD/CAM/Robotic integration method

背景:生物型股骨柄假体无菌松动是全髋关节置换失败的主要因素,减少无菌松动的先决条件是增加股骨柄假体在股骨髓腔中的填充率。目的:得到定制式股骨柄假体在髓腔中的填充率,验证计算机辅助设计/计算机辅助制造/工业机器人加工(CAd/CAM/rObOTIC)集成方法和机器人磨削的有效性。方法:利用CT数据重建股骨髓腔三维模型,在此三维模型基础上设计股骨柄假体的柄体,依据标准直柄股骨柄假体近端模型设计股骨柄假体的其余部分。将设计的股骨柄假体模型导入CAd/CAM/rObOTIC集成系统生成机器人磨削轨迹,利用该轨迹对股骨柄假体进行磨削加工。将加工好的股骨柄假体与股骨髓腔匹配,分析股骨柄假体在髓腔中的填充率。结果与结论:实验结果表明,定制式股骨柄假体在髓腔中有良好的填充率,髓腔的解剖结构可以阻止股骨柄假体的扭转,获得股骨柄假体在髓腔中的稳定固定。BACKGROUND: In total hip replacements, aseptic loosening of uncemented femoral hip prosthesis is the main reason for the failure of artificial hip replacement, the prerequisite of reducing aseptic loosening of prosthesis is to increase filling area of femoral prosthesis in femoral cavity.OBJECTIVE: To obtain the filling rate of customized femoral prosthesis in femoral cavity and verify the validity of the methods of CAD/CAM/Robotic integration and the robot grind.METHODS: In this paper, the CT data of femur were used to reconstruct three-dimensional model of femoral cavity.According to this model, a custom uncemented femoral hip prosthesis was designed, then the model of this custom prosthesis was imported into the CAD/CAM/Robotic software to generate cut path.After the cut path was imported into the robotic controller, the custom prosthesis can be fabricated, then this custom prosthesis was inserted into the femoral cavity, and the filling result of the custom prosthesis in femoral cavity was analyzed.RESULTS AND CONCLUSION: The experiment results showed that the customized prosthesis in femoral cavity achieved good filling result, the structure of femoral cavity resisted the rotation of the customized prosthesis in femoral cavity, and the customized prosthesis obtained stable fixation in the femoral cavity

优化固氮活性模型信息研究──双齿配体DPPE和DPPM对固氮酶促反应的影响

报道了某些双齿配体对固氮酶促反应影响的研究结果．发现１，２－双（二苯基磷）－乙烷（ＤＰＰＥ）对固氮酶酶促乙炔还原反应有促进作用，但同时又抑制了固氮酶的放氢反应。而比ＤＰＰＥ少一个－ＣＨ２－链的双（二苯基磷）－甲烷（ＤＰＰＭ）却不能表现出对固氮酶促乙炔还原活力的促进作用．对照固氮酶ＭｏＦｅ－蛋白Ｘ－光衍射结构分析结果和量子化学近似计算所导出的固氮酶活性中心结构模型提出了ＤＰＰＥ促进酶促乙炔还原反应的一种可能的解释
