包虫囊液外溢致过敏性休克抢救体会

目的探讨各种原因导致包虫囊肿破裂后囊液外溢致过敏性休克的诊断及抢救措施。方法回顾性分析33例各脏器包虫囊肿破裂后发生过敏性休克患者的临床资料、诊疗方法及效果。结果本组患者主要临床症状有:胸痛或腹痛、喉头水肿、呼吸困难、全身瘙痒、过敏性休克等;在立即通畅呼吸道、迅速建立静脉通道,使用血管活性药物升压、扩容,使用抗变态反应药物,手术清除过敏原后存活30例,死亡3例。结论选择快速实用的诊断方法确诊:如嗜酸粒细胞计数、包虫囊液皮内试验、补体结合试验和间接血凝试验及CT、B超,通畅呼吸道、抗过敏、扩容、升压,积极抢救及手术可提高抢救成功率

新疆农田化肥施用现状调查与评价/Investigation and Evaluation of the Chemical Fertilizer Application Situation of Farmland in Xinjiang[J]

以新疆2005-2011年测土配方施肥项目为基础,采用农户抽样调查的方法,对测土配方施肥项目87个县(市)的363 645户调查数据进行分析和评价.结果表明:新疆耕地的化肥施用量为377.55 kg·hm-2,N、P2O5、K2O比例为1∶0.62∶0.08.小麦的化肥施用量345.45 kg·hm-2,N、P2O5、K2O化肥施用比例为1∶0.62∶0.05,化肥效率为15.7 kg·kg-1;玉米的化肥施用量372.45 kg·hm-2,N、P2O5、K2O比例为1∶0.62∶0.07,化肥效率为28.18 kg·kg-1;棉花化肥施用量451.50 kg·hm-2,N、P2O5、K2O比例为1∶0.58∶0.07,化肥效率为10.88 kg· kg-1;葡萄化肥施用量659.25 kg·hm-2,N、P2O5、K2O比例为1∶0.89∶0.33,化肥效率为59.62 kg· kg-1.新疆肥料投入区域差异较大,南疆单位面积用肥量明显高于北疆,南疆化肥施用量474.45 kg·hm-2,北疆化肥施用量317.85 kg· hm-2.施肥量还存在经济作物高于普通作物的现象

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
