目的研究不同种类菜肴中亚硝酸盐含量随时间的变化情况。方法购买不同种类的常见市售蔬菜,模拟常用蔬菜烹饪方法和储存条件,用盐酸萘乙二胺分光光度法测量新鲜蔬菜中的亚硝酸盐含量。分别在室温(20℃)及冷藏(4℃)条件下,于0~48 h内的不同时间点,对烹饪后蔬菜中的亚硝酸盐含量进行检测,比较不同种类蔬菜炒制后亚硝酸盐的变化趋势。结果新鲜蔬菜中的亚硝酸盐含量均远远低于国家标准。常温下放置16~32h后,炒制后叶类蔬菜中的亚硝酸盐含量升高,并有严重超标的情况出现。常温放置48h的炒油菜中,亚硝酸盐含量最高,达到388.34 mg/kg。常温放置的炒胡萝卜也出现了超标情况,最高点为33.24 mg/kg。低温冷藏可以显著抑制菜肴中亚硝酸盐含量的增加(P<0.05),24 h之后的抑制效果尤其明显。结论不同种类蔬菜炒制后,随着时间的延长,均伴随着亚硝酸盐含量的增加,日常生活中,建议剩菜放入冰箱冷藏,尤其是叶类蔬菜,应尽快食用。

目的比较单纯电切、单纯电凝和电凝电切术对直径为5~10 mm扁平肠息肉的疗效及不良事件发生率的影响。方法前瞻性纳入2021年3月至2023年3月于解放军总医院第四医学中心就诊的221例直径5~10 mm的扁平肠息肉患者,经纳入排除标准筛选,同时剔除不愿参与研究及中途退出者,最终纳入195例患者作为研究对象。根据随机字母表法将所有患者分为单纯电切组、单纯电凝组、电凝电切术组,每组65例患者。观察比较三组患者的完全切除率、息肉复发率、手术及住院情况、胃肠道功能恢复时间、不良事件发生率和患者满意度。结果术后,电凝电切术组的完全切除率为96.92%,显著高于单纯电切组(81.54%)和单纯电凝组(84.62%)。尽管三组在息肉复发率上差异不显著,但电凝电切术组的不良事件发生率显著低于其他两组,仅为1.54%。此外,电凝电切术组的手术、恢复和住院时间也都显著短于单纯电切和单纯电凝组,同时在胃肠道功能恢复时间方面也表现更好,患者满意度更高。结论相比于单纯电切或电凝,电凝电切术治疗直径为5~10 mm的扁平肠息肉疗效更好,能更快促进胃肠道功能恢复,且不良事件发生率低,患者满意度高。

When and how the Tibetan Plateau formed and maintained its thick crust and high elevation on Earth is continuing ***,the coupling relationship between crustal thickening and corresponding paleoelevation changing has not been well *** dominant factors in crustal thickness changing are crustal shortening,magmatic input and surface erosion *** thickness change and corresponding paleoelevation variation with time were further linked by an isostatic equation in this *** 120 Ma crustal shortening,magmatic input and surface erosion rates data from the central Tibetan Plateau are took as input *** using a one-dimensional isostasy model,the authors captured the first-order relationship between crustal thickening and historical elevation responses over the central Tibetan Plateau,including the Qiangtang and Lhasa *** on the modeling results,the authors primarily concluded that the Qiangtang terrane crust gradually thickened to ca.63 km at ca.40 Ma,mainly due to tectonic shortening and minor magmatic input combined with a slow erosion ***,the Lhasa terrane crust thickened by a combination of tectonic shortening,extensive magmatic input and probably Indian plate underthrusting,which thickened the Lhasa crust over 75 km since 25 ***,a longstanding elevation>4000 m was strongly coupled with a thickened crust since about 35 Ma in the central Tibetan Plateau.

Continuous microwave propagation through a time-varying plasma and frequency up-conversion has been demonstrated by particle-in-cell (PIC) simulation. In principle, it is possible to transform a 2.45 GHz source radiation to an arbitrary larger frequency radiation. The energy conversion is also obtained by the theoretical analysis and has been testified by PIC simulation. The source wave was propagating in a parallel plate waveguide locally filled with the ionized gas. In this paper we would discuss the effects of the rise time, the plasma length, the switching time and the collision frequency on the energy conversion, and the methods to improve the upshift wave energy are proposed. We also put forward the new concept of the critical values of the rise time and the source wave amplitude to provide a theoretical basis for the selection of parameters in the experiments.
