背景:假体周围感染是关节置换后医生及患者最不愿意遇到的并发症之一,其顽固性和难治性一直是让关节科医生头痛的难题。目的:综述国内外近年临床最新治疗髋、膝关节置换后假体周围感染的常用临床治疗手段,包括抗生素治疗、手术治疗、生物治疗、中医药治疗等,以期促进国内治疗假体周围感染的研究进展。方法:第一作者检索中国知网(CNKI)、万方、维普、PubMed等数据库2000年1月至2022年10月的文献,通过阅读题目初筛获得762篇文献,然后通过阅读摘要,排除内容重复、数据可靠性低、观点过时的文献后获得194篇文献,再通过精读原文最终纳入88篇文献。结果与结论:(1)治疗假体周围感染过程中,组合型抗生素给药方案或有助于根除感染;(2)Ⅱ期翻修术仍是治疗假体周围感染的金指标;(3)Ⅰ期翻修术缺乏大样本的临床研究,需要更多的临床观察;(4)生物治疗中的噬菌体疗法、新式载药系统已少量应用于临床,在假体周围感染的预防和根除上表现出其优势特点;(5)中医药配合抗生素、手术治疗手段能提高预防、治疗假体周围感染的效果,但缺乏高等级的循证医学证据。

为强化纳米零价铁(nZVI)在多孔介质中的传输,采用膨润土悬浮液携带高岭土负载纳米零价铁(K-nZVI)。通过沉降试验和流变性试验确定了修复剂中膨润土和K-nZVI掺量最佳配比;开展模拟柱试验,探讨了不同注入压力下K-nZVI在多孔介质中的迁移特性;结合数值模拟,分析了修复剂配比和注入压力对K-nZVI扩散半径的影响规律。试验结果表明,膨润土悬浮液能显著提高K-nZVI的稳定性和分散性;膨润土和K-nZVI最佳掺量分别为5%和0.4%;膨润土悬浮液携带K-nZVI修复剂注入多孔介质中时存在临界注入压力。数值模拟结果表明,K-nZVI扩散半径与注入压力呈正相关,与修复剂黏度呈负相关。本文研究结果可为有色冶炼场地重金属污染修复工程提供理论指导。

射频接收线圈是磁共振成像(MRI)系统中的关键部件,用于检测变化的磁场,其性能直接影响图像的质量。超低场MRI射频接收线圈工作在较低频率,其阻抗特性不同于传统临床MRI射频接收线圈。理论上正交接收线圈比单通道线圈的信噪比(SNR)可以提高41%。而与阵列线圈相比,正交接收线圈可以用更低的成本与设计复杂度达到很好的成像效果。因此该文研究了一种用于超低场MRI(50.4 mT)系统的膝关节正交接收线圈,它由鞍形线圈和亥姆霍兹线圈组成。首先,确定了线圈的支撑结构及尺寸,并通过计算单匝接收线圈的效率及磁场的不均匀性来确定鞍形以及亥姆霍兹线圈的最优尺寸。然后,实测了线圈交流电阻,来评估线圈不同匝数的SNR,发现匝数增多会使得交流电阻显著增加,从而使SNR随着线圈匝数增加先增加后减少。最后,得到了两线圈的最佳匝数,并制作了正交接收线圈,从CuSO_(4)·5H_(2)O体膜以及体内膝关节成像来评估正交接收线圈的性能。在体膜和体内膝关节成像中,正交接收线圈与单通道线圈相比,图像SNR分别最大程度地提升了约33.5%和30.9%。
