Nanostructured Fe70Si20Cr10 alloy was produced by high energy planetary ball milling, starting from elemental powders. The structural, microstructural and magnetic properties of the milled powders were characterized by X-ray diffraction, scanning electron microscopy, vibrating sample magnetometer and 57Fe M6ssbauer. After 5 h of milling, it is observed the formation of a bcc solid solutions ~t-Fe （Si, Cr）. Its grain size decreases with increasing milling time attaining 20 nm after 15 h of milling time. Analysis of M6ssbauer spectra shows an increasing broad magnetic component when the milling time increases. Its mean hyperfme field is about 25.5 T at 15 h of milling. M-H hysteresis loop curves reveal a room temperature ferromagnetic behaviour with a saturation magnetisation reaching 143 emu/g after 15 hours of milling, which is 20% lower than that of bulk iron; i.e., 1800 emu/g, due to effect of alloying elements after the formation of ct-Fe （Si, Cr） solid solution.

背景手术后恶心、呕吐（PONV）是门诊手术常见的并发症。本试验目的是观察透皮东莨菪碱贴剂（TDS）联合静脉注射昂丹司琼（OND）对门诊患者PONV的疗效是否优于单独应用昂丹司琼。方法此项随机双盲多中心的临床试验纳入了620例接受门诊腹腔镜或隆胸手术的PONV高危女性患者，进入手术室前2小时分别给患者贴上TDS贴剂或外观相同的空白贴剂。在全麻诱导前2—5分钟给所有患者静脉注射OND4mg。手术后24~48小时评估止吐是否完善（彻底止吐标准为无呕吐或干呕，且没有追加止吐药）。同时记录发生呕吐、干呕、恶心以及追加止吐药的患者比例，记录手术后首次发生PONV的时间及离院时间，记录呕吐、干呕、恶心的发作次数与严重程度及患者对于止吐治疗的满意度。结果TDS＋OND组与OND组相比，手术后24小时恶心、呕吐的发生率显著降低，但手术后48小时两者差异无显著性。TDS＋OND组没有呕吐、干呕且未追加过止吐药的患者占48％，而OND组占39％（P〈0．02）。TDS＋OND组的彻底止吐（无恶心、呕吐或干呕，且未追加止吐药）率显著高于OND组（分别为35％和25％，P〈0．01）。TDS＋OND组手术后首次发生恶心、呕吐、干呕及追加止吐药的时间明显晚于OND组（P〈0．05）。前者不良反应的总发生率也低于后者（分别为36．7％和49％，P〈0．01）。结论与单独应用OND相比。TDS＋OND能更大程度地减少PONV，主要是通过减少不良反应而获得。
