A Tentative Study of Light Punishment for Duty Crime and Countermeasures

目前我国职务犯罪轻刑化问题凸显,职务犯罪缓免刑的高适用率、自首情节的适用较为普遍、法定情节量刑失衡,执行阶段的待遇特殊化较为突出。针对职务犯罪轻刑化问题,本文提出建立和加强对职务犯罪案件的监督制约机制,完善职务犯罪相关立法,制约法官自由裁量权等举措,以矫正职务犯罪轻刑化的司法趋向。At present, light punishment for duty crime has become a serious problem in China. There exist a high rate of probation and exempt from punishment, a wide application of volunteer surrender to court, an unbalanced legal measurement for penalty and special treatment in execution. In this paper, measures are put forward to curb light punishment for duty crime in judicature such as setting up and strengthening supervision and restriction mechanism for cases of duty crime, optimizing legislation for duty crime and restricting discretion of judges.广西壮族自治区检察院第四批检察理论研究立项课题(项目编号:GJ2011B01)的阶段性成

营养不良大鼠血浆小分子物质代谢组学的研究

目的：利用代谢组学方法检测能反应营养不良大鼠血浆小分子代谢物质，探讨代谢组学在营养不良研究中的应用。方法：实验分为营养不良组和对照组。对照组大鼠自由进食、饮水，营养不良组自由进水，每天给予该体质量大鼠所需食物的60％。造模成功后，收集大鼠血浆，用液质分析（LC—MS）方法检测并比较两组大鼠血浆小分子物质。结果：营养不良组大鼠与对照组相比，血浆中肉毒碱和色氨酸碎片含量增加，而甜菜碱、棕榈酰肉碱、亚麻酸、二十二碳六烯酸和花生四烯酸等含量均降低。结论：用LC—MS方法检测得到的小分子物质与大鼠营养不良相关。代谢组学可作为营养不良指标的筛选方法

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
