癌症患者的心身状况及心理干预

【: 目的】研究癌症患者的心身状况及心理干预对心身状况的影响。【方法】采用症状自评量表( SCL- 90) 、焦虑自评量表( SAS) 、抑郁自评量表( SDS) 评定癌症组(72 例)、肝炎对照组(30 例)及健康对照组(30 例)的 心身状况, 并随机将72 例癌症患者分为两组, 干预组(40 例)接受生物学治疗及心理干预, 对照组(30 例)只接 受生物学治疗, 治疗后用上述量表再评定一次。【结果】癌症组的SAS 标准分、SDS 抑郁指数及各项抑郁特异症 状评分、SCL-90 总分、阳性均分、躯体化、抑郁、焦虑因子分高于肝炎组和健康组( P< 0.01) ; 干预组SAS 标准 分、SDS 指数、SCL-90 总分、躯体化、抑郁、焦虑及敌对因子分干预后评定显著低于干预前( P< 0.01) , SAS 标准 分、SDS 指数、SCL-90 抑郁因子的减分值显著高于对照组( P< 0.01) 。【结论】癌症患者有明显的焦虑抑郁症状, 心身状况较差; 心理干预能有效改善癌症患者的焦虑抑郁情绪, 减轻心理症状

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
