目的体位监测在神经外科鼻饲患者风险管理中的应用价值。方法选择我院神经外科2020年1-12月昏迷鼻饲患者415例,将其随机分组分为各162例的对照组和试验组。对照组采取设立床头抬高0°~30°,试验组以抬高床头30°~45°,随后试验组鼻饲患者并随机分为三组,各54例,其中A组选择平卧仰卧体位,B组则选择左侧卧位,C组选择右侧卧位进行患者体位管理。监测床头角度与昏迷鼻饲患者并发症的相关性。结果组间床头抬高30°~45°有效率结果对比,试验组高于对照组,P0.05。结论床头角度的监测能够有效地预防鼻饲患者并发症的发生,建议密切关注患者进食后的30 min~2 h内体位的变化。当体位角度低于30°时,鼻饲患者的发生风险增加,应及时采取预防措施,左侧卧位可降低鼻饲并发症的发生率。

以已有文献中有关施氮对中国凤丹生长和籽粒产量影响的评估结果为统计样本,采用Meta分析法,构建施氮量对凤丹影响的损失函数,为评估模型研究提供可靠的数据基础。研究结果表明:当施氮水平为I3(150~199 kg·hm^(-2))时,最能满足凤丹高产的需求;当氮含量过高时,凤丹籽粒产量增长率会有所下降。施氮量对株高的影响呈先降后升趋势,当施氮水平为I_(14)时(700~749 kg·hm^(-2)),增高率达到峰值。

为探究紫苏和姜汁作为去腥剂对烤武昌鱼的风味影响,该实验选用紫苏精油和姜汁腌制武昌鱼后经烤箱加工制成样品,通过电子鼻、电子舌等仪器以及对挥发性风味成分、游离氨基酸、呈味核苷酸的检测对其风味物质进行了研究分析。结果表明紫苏精油和姜汁的腌制可以使烤武昌鱼在色泽、气味和滋味上均呈现较大差异。与对照组相比,紫苏精油和姜汁可以减少腥味物质的形成,并产生掩盖腥味的物质,其中1-辛烯-3-醇含量减少为0.74 ng/g,α-松油醇、芳樟醇、莰烯、β-蒎烯等香料物质的增加,从而使得武昌鱼的风味更丰富。紫苏&姜汁组的烤武昌鱼的鲜味物质GMP的含量高达87.75 mg/g,苦味物质HxR的含量低至为4.49 mg/g,且苦味氨基酸含量远低于其他组,同时其EUC(味精当量)含量最高为224.83 g MSG/100 g。综上所述,紫苏精油和姜汁可以改善烤武昌鱼的风味和滋味。
