The proton-proton(pp)fusion chain dominates the neutrino production in the *** uncertainty of the predicted pp neutrino flux is at the sub-percent level,whereas that of the best measurement is O(10%).In this study,for the first time,we measure solar pp neutrinos in the electron recoil energy range from 24 to 144 keV using the PandaX-4T commissioning data with 0.63 tonne×year *** pp neutrino flux is determined as(8.0±3.9(stat)±10.0(syst))×1010 s^(-1)cm^(-2),which is consistent with the Standard Solar Model and existing measurements,corresponding to an upper flux limit of 23.3×10^(10)s^(-1)cm^(-2)at 90%C.L..

目的探讨1,3-β-葡聚糖诱导炎症小鼠的肺组织自噬水平,为肺组织炎症的预防、诊断及治疗提供依据。方法将20只实验小鼠分为两组,1,3-β-葡聚糖实验组、生理盐水对照组,每组10只。小鼠非暴露气管灌注1,3-β-葡聚糖,于灌注后第3天、第28天分别收集小鼠肺组织。采用苏木素伊红和Masson染色,观察肺组织病理改变;采用Western blot检测小鼠体内自噬特异性蛋白微管相关蛋白1轻链3(LC3)和自噬相关蛋白sequestosome 1(p62)的表达水平。结果镜下可见,与对照组相比,实验组小鼠肺组织出现大量炎症细胞和胶原沉积。Western blot结果显示,实验组小鼠体内LC3-Ⅱ表达水平较对照组升高(t=-2.932,P<0.05),p62表达水平较对照组升高(t=-5.151,P<0.05)。结论1,3-β-葡聚糖可明显著提高小鼠肺组织自噬特异性蛋白LC3及自噬相关蛋白p62的表达水平,证明肺组织炎症的小鼠细胞自噬水平升高。

Ⅰ.INTRODUCTION The direct detection of dark matter particles,especially the weakly interacting massive particles(WIMPs),is being actively carried out by a couple of experiments worldwide[1].In recent years,the PandaX-Ⅱ experiment located in the China Jinping Underground Laboratory(CJPL)[1-3],which uses the technology of dual phase liquid xenon time projection chambers(TPCs),has pushed the limits of the cross section between WIMPs and nucleons to a new level for most of the possible WIMP masses;other experiments of the same type are also being performed[4–10].
