目的探讨靶控输注舒芬太尼或瑞芬太尼用于妇科腹腔镜手术麻醉的临床效果。方法将2015年1月-2016年6月择期行妇科腹腔镜手术患者(70例)随机分为异丙酚复合瑞芬太尼组(PR组,n=35)和异丙酚复合舒芬太尼组(PS组,n=35),PR组设定瑞芬太尼血浆靶浓度为4ng/mL,实施异丙酚(3μg/mL)及瑞芬太尼复合靶控输注,PS组设定舒芬太尼靶控浓度为0.5ng/mL,实施异丙酚(3μg/mL)及舒芬太尼复合靶控输注。统计异丙酚的用量,比较2组麻醉前(T_0)、诱导后3min(T_1)、插管时(T_2)、切皮(T_3)、腹腔探查时(T_4)、拔管(T_5)时收缩压(SBP)、舒张压(DBP)和心率(HR)的差异,观察2组术后睁眼时间、拔管时间等指标。对2组术后视觉模拟评分(VAS)和警觉-镇静评分(OAAS)进行比较。结果 T_1时2组患者SBP、DBP及HR较T_0时降低,差异有统计学意义(P<0.05)。PR组T_1时SBP、DBP低于PS组,T_5时PR组SBP、DBP、HR高于PS组,差异均有统计学意义(P<0.05)。PS组呼吸恢复时间、苏醒睁眼时间、拔管时间、定向力恢复时间较PR组长,PS组术后60、90、120min VAS评分低于PR组,差异有均统计学意义(P<0.05)。结论舒芬太尼异丙酚靶控输注围术期血流动力学更加平稳,舒芬太尼可以发挥更为显著的镇痛效能。

Due to significant differences in biotic and abiotic properties of soils compared to those of sediments,the predicted underlying microbe-mediated mechanisms of soil carbon emissions in response to warming may not be applicable for estimating similar emissions from inlandwater *** addressed this issue by incubating different types of sediments,(including lake,small river,and pond sediments)collected from 36 sites across the Yangtze River basin,under short-term experimentalwarming to explore the effects of climatewarming on sediment carbon emission and the underlying microbe-mediated *** results indicated that under climate warming Cc emissions were affected more than CH_(4) emissions,and that pond sediments may yield a greater relative contribution of CO_(2) to total carbon emissions than lake and river ***-induced CO_(2) and CH_(4) increases involve different microbe-mediated mechanisms;Warming-induced sediment CO_(2) emissions were predicted to be directly positively driven by microbial community network modularity,which was significantly negatively affected by the quality and quantity of organic carbon and warming-induced variations in dissolved oxygen,Conversely,warminginduced sediment CH_(4) emissionswere predicted to be directly positively driven bymicrobial community network complexity,which was significantly negatively affected by warminginduced variations in *** findings suggest that biotic and abiotic drivers for sediment CO_(2) and CH_(4) emissions in response to climate warming should be considered separately when predicting sediment organic carbon decomposition dynamics resulting from climate change.

研究了抹茶的不同遮阴时间对其内含成分及其加工蛋糕品质的影响.研究发现:遮阴有利于氨基酸、咖啡碱、叶绿素、蛋白质、等含氮化合物的合成,不利于茶多酚和茶多糖等含碳化合物的积累.遮阴时间越长,叶绿素含量越高,抹茶色泽越绿.抹茶蛋糕经烘焙后,绿色程度降低.遮阴时间较长的抹茶受自身色泽的影响,所烘焙出的抹茶蛋糕色泽较绿.因此,可以通过添加不同遮阴时间的抹茶来调整蛋糕的口感、风味和色泽.

The catalytic effect of FeCoNiCrMo high entropy alloy nanosheets on the hydrogen storage performance of magnesium hydride(MgH_(2))was investigated for the first time in this *** results demonstrated that 9wt%FeCoNiCrMo doped MgH_(2)started to dehydrogenate at 200℃and discharged up to 5.89wt%hydrogen within 60 min at 325℃.The fully dehydrogenated composite could absorb3.23wt%hydrogen in 50 min at a temperature as low as 100℃.The calculated de/hydrogenation activation energy values decreased by44.21%/55.22%compared with MgH_(2),***,the composite’s hydrogen capacity dropped only 0.28wt%after 20 cycles,demonstrating remarkable cycling *** microstructure analysis verified that the five elements,Fe,Co,Ni,Cr,and Mo,remained stable in the form of high entropy alloy during the cycling process,and synergistically serving as a catalytic union to boost the de/hydrogenation reactions of MgH_(2).Besides,the FeCoNiCrMo nanosheets had close contact with MgH_(2),providing numerous non-homogeneous activation sites and diffusion channels for the rapid transfer of hydrogen,thus obtaining a superior catalytic effect.
