LXI(LAN-based Extensions for Instrumentation)技术的提出进一步推动了测试测量领域的发展,基于IEEE1588精确时钟同步协议的时间同步触发是LXI B类仪器的一个主要特点。本文介绍了IEEE1588精密时钟协议,详细分析了其同步原理,并介绍了一种实现IEEE1588协议的方案,从时钟通过与主时钟交换报文获取时间戳,根据时间戳计算出与主时钟的时间偏差并对自己的时钟进行修正。最后对所设计的系统进行了测试,测试结果显示系统能实现时钟同步。

目的探讨胫骨横向骨搬移微血管网再生技术结合高压氧治疗伴溃疡形成的糖尿病足的临床疗效。方法对2015年11月至2017年3月利用胫骨横向骨搬移微血管网再生技术结合高压氧治疗的21例糖尿病足溃疡患者（治疗组）进行回顾性分析，并与同期利用高压氧治疗的21例糖尿病足溃疡患者（对照组）进行比较。治疗组术中于患侧胫骨中段内侧面上做一范围约2 cm×10 cm骨窗，安置专用横向外固定牵引架，同时行患足清创术，术后第1天开始采用多人高压氧舱治疗，压力为0.20 MPa，1次/d，10 d为1个疗程，共3个疗程，第5天开始缓慢横向搬移骨窗（1 mm/d）；对照组行患足清创术，术后第1天行高压氧治疗，治疗方案同治疗组。观察2组创面愈合时间，术前、术后3个月踝肱指数（ABI）及密歇根神经体征评分（MNSI）。结果2组患者均获随访，平均随访9.3个月，对照组中1例Wagner Ⅴ级患者创面未愈合，最终截肢，其余患者创面均得到愈合，平均愈合时间为（39.52±8.43）d，治疗组创面均得到愈合，平均愈合时间为（31.74±6.12） d；治疗组ABI由术前的0.56±0.18，术后3个月升至0.94±0.16，MNSI由术前的5.92±1.13，术后3个月降至4.11±1.25，对照组ABI由术前的0.54±0.21术后3个月升至0.81±0.20，MNSI由术前的5.74±1.26；术后3个月降至4.98±1.34。2组创面愈合时间比较差异有统计学意义（P〈0.05），2组术后3个月ABI及MNSI较术前差异均有统计学意义（P〈0.01）。治疗组优于对照组，差异有统计学意义（P〈0.05）。结论胫骨横向骨搬移微血管网再生技术可以重建患肢小腿以下微血管网，促进周围血管及周围神经恢复，结合高压氧可促进创面愈合，具有手术简便、疗效确切，保肢成功率高的优点，是治疗糖尿病足溃疡的理想方法之一。

When there is substantial heterogeneity of treatment effectiveness for comparative treatmentselection, it is crucial to identify individualised treatment rules for patients who have heterogeneous responses to treatment. Existing approaches include directly modelling clinical outcomeby defining the optimal treatment rule according to the interactions between treatment andcovariates and outcome weighted approach that uses clinical outcome as weights to maximise atarget function whose value directly reflects correct treatment assignment. All existing articles ofestimating individualised treatment rules are all assuming just two treatment assignments. Herewe propose an outcome weighted learning approach that uses a vector hinge loss to extend estimating individualised treatment rules in multi-category treatments case. The consistency of theresulting estimator is shown. We also demonstrate the performance of our approach in simulationstudies and a real data analysis.

关键词： Heterogeneity of treatment effectiveness individualised treatment rule risk bound RKHS weighted multi-category support vector machine
