目的探讨腹腔镜模拟训练机对不同临床经验参与者的培训效果。方法在腹腔镜模拟机上培训9名无任何临床经验的志愿者(对照组)、9名6年级医学实习生(学生组)和9名有2～3年临床经验的住院医生(医生组),包括0°、30°腹腔镜的操作、眼-手协调、钛夹应用、抓-钳夹、剪切、电凝和物体转运,每天训练30min,共5d,比较培训前后各组的得分。结果培训前3组在0°、30°腹腔镜的操作,抓-钳夹,电凝,眼-手协调得分都有统计学差异(P<0.05);培训后各组在0°腹腔镜的操作、抓-钳夹、眼-手协调的得分有统计学差异(P<0.05)。所有参与者培训后在0°、30°腹腔镜操作、电凝得分和眼-手协调得分和时间均较培训前明显提高(P<0.05)。结论腹腔镜模拟训练机培训可以提高不同临床经验参与者的腹腔镜操作技巧,并且可以区分不同临床经验者。

The cycloaddition of epoxides and carbon dioxide represents a straightforward and atom-efficient method for synthesis of cyclic carbonates and utilization of CO2. so far, homogeneous metal complexes have been mainly applied for such transformations. Here, we describe the synthesis of novel heterogeneous Zn-based catalysts, which were conveniently prepared by pyrolysis of an active- carbon-supported phenanthroline-ligated Zn(OAc)2 complex. Detail structural characterizations proved the existence of single zinc sites in the active material. Compared to a Zn-based nanoparticle (Zn-NP) catalyst, the resulting single metal atom catalyst (sAC) displayed improved activity and stability for the cycloaddition of epoxides. By applying the optimal catalyst, a variety of carbonates were successfully obtained in high yields with good functional group tolerance.
