During the 2016-17 and 2018-19 running periods, the bESⅢ experiment collected 7.5 fb-1of e~+e~- collision data at center-of-mass energies ranging from 4.13 to 4.44 GeV. These data samples are primarily used for the study of excited charmonium and charmoniumlike states. by analyzing the di-muon process e~+e~-→(γISR/fSR)μ~+μ~-, we measure the center-of-mass energies of the data samples with a precision of 0.6 MeV. Through a run-by-run study, we find that the center-of-mass energies were stable throughout most of the data-collection period.

目的探究tRNA衍生的小RNA(tsRNA)对小鼠心肌细胞铁死亡的调控作用及其机制。方法采用实时荧光定量PCR(RT-qPCR)检测8周龄C57bl/6j小鼠心脏、肝脏、脾脏、肾脏、大脑、肌肉中5′tRf-lysCTT的相对表达水平。将原代心肌细胞分为A~D组,A组细胞使用完全培养基培养60 h,b组先使用完全培养基培养24 h,再依次进行饥饿处理12 h,h/R处理24 h,C组和D组细胞分别转染antagomir-NC和antagomir-5′tRf-lysCTT,并于转染24 h后再依次进行饥饿(12 h)和h/R处理(12 h);将原代心肌细胞分为E~G组,E组细胞使用完全培养基培养24 h,f组细胞转染agomir-NC 24 h,G组心肌细胞转染agomir-5′tRf-lysCTT 24 h。采用RT-qPCR检测A~G组小鼠心肌细胞中5′tRf-lysCTT和Ptgs2、Gpx4、Slc7a11的相对表达水平,分别采用亚铁离子比色法测试盒、脂质活性氧(ROS)染色、CCk8试剂盒检测A~G组小鼠心肌细胞内亚铁离子相对水平、ROS水平及心肌细胞的存活率,采用普鲁士蓝染色试剂盒观察A~G组小鼠心肌细胞内铁离子沉积情况。结果RT-qPCR检测结果显示,与肝脏、脾脏、肾脏、大脑、肌肉中相比较,小鼠心脏中5′tRf-lysCTT表达水平最高(f=16.21,t=3.81~7.93,Pb组相比,心肌细胞内5′tRf-lysCTT和Ptgs2相对表达水平降低、Gpx4以及Slc7a11相对表达水平升高、亚铁离子相对水平和ROS水平降低,心肌细胞的细胞存活率升高(t=3.26~15.61,Pb组相比,细胞内的上述指标的水平差异无显著性(P>0.05)。G组与E组相比,心肌细胞内5′tRf-lysCTT和Ptgs2相对表达水平升高、Gpx4和Slc7a11相对表达水平降低、亚铁离子相对水平和ROS水平升高,心肌细胞的细胞存活率降低(t=3.57~91.84,Pf组与E组相比,细胞内的上述指标的水平比较差异无显著性(P>0.05)。结论5′tRf-lysCTT对于小鼠心肌细胞铁死亡具有调控作用,敲低细胞内5′tRf-lysCTT可以抑制h/R诱导的心肌细胞铁死亡,而过表达5′tRf-lysCTT可促进心肌细胞铁死亡的发生。

The water Cherenkov Detector Array(wCDA) is a major component of the large high Altitude Air Shower Array Observatory(lhAASO), a new generation cosmic-ray experiment with unprecedented sensitivity, currently under construction. wCDA is aimed at the study of TeV γ-rays. In order to evaluate the prospects of searching for TeV γ-ray sources with wCDA, we present a projection of the one-year sensitivity of wCDA to TeV γ-ray sources from TeVCat using an all-sky approach. Out of 128 TeVCat sources observable by wCDA up to a zenith angle of 45°, we estimate that 42 would be detectable in one year of observations at a median energy of 1 TeV. Most of them are Galactic sources, and the extragalactic sources are Active Galactic Nuclei(AGN).

Using inclusive decays of j/ψ aprecise determination of the number of j/ψ events collected with the bESIII detector was *** the two data sets taken in 2009 and 2012,the numbers of j/ψ events were recalculated to be(224.0±1.3)×10^(6) and(1088.5±4.4)×10^(6),respectively;these numbers are in good agreement with the previous measurements. for the j/ψ sample taken in 2017-2019,the number of events was determined to be(8774.0±39.4)×10^(6).The total number of j/ψ events collected with the bESIII detector was determined to be(10087±44)×10^(6),where the uncertainty is dominated by systematic effects,and the statistical uncertainty is negligible.

目的探索单纯紫外线照射法建立黄褐斑小鼠模型的适宜照射能量及频率,为成功建立黄褐斑模型提供动物品系及照射方案参考。方法使用bAlb/c雌鼠及C57bl/6jNifdc雌鼠建立黄褐斑动物模型,采用简单随机方法,将bAlb/c雌鼠分为A、b、C、G 4组,每组各5只;将C57bl/6jNifdc雌鼠分为D、E、f、h 4组,每组各5只。所有小鼠均采用8.428 mw/cm^(2)紫外光予以照射,A、D组照射时间为15 s(单次照射能量为0.13 j/cm^(2)),b、E组照射时间为15 min(单次照射能量为7.59 j/cm^(2)),C、f组照射时间为30 min(单次照射能量为15.17 j/cm^(2)),连续5 d照射后停止2 d为1个周期,共照射4个周期;G、h组不予照射。照射结束后,所有小鼠正常饲养,并于1周后取材(每组3只),行hE、Masson-fontana、Masson、免疫组化染色,分别测定棘细胞层厚度、黑色素颗粒数、胶原百分比、白细胞介素-1(Il-1)水平。其余小鼠继续饲养1周,脱毛并拍照,观察色斑变化。使用SPSS 27.0软件进行数据分析,不符合正态分布的计量资料采用M(Q 1,Q 3)表示,组间比较采用kruskal-wallis秩和检验。结果在全程照射过程中,bAlb/c雌鼠各组始终未形成肉眼可见的色斑,而在C57bl/6jNifdc雌鼠中,第2周照射后D、E、f组均产生不同大小的色斑,然而第3周照射后,D组色斑逐渐消失,E组色斑则较前更加明显,与此同时,f组也产生了明显的色斑和部分小鼠背部皮肤出现脱屑甚至灼伤破损。第4周照射后,D组无新色斑形成,E组色斑更为明显,f组大部分出现皮肤灼伤破损。照射结束后2周,各组bAlb/c雌鼠背部皮肤无明显色斑,而在C57bl/6jNifdc雌鼠中,D组无明显色斑,E组色斑颜色较第4周照射后变浅,f组皮肤灼伤破损处结痂,色斑较前变浅,但E、f组色斑仍明显肉眼可见。hE染色显示,A、b、C、G组棘细胞层厚度差异无统计学意义(h=1.08,P=0.782);而D、E、f、h组棘细胞层厚度差异有统计学意义(h=12.85,P=0.005),随着单次照射时间的延长,棘细胞层厚度逐渐变薄,f组表皮棘细胞排列有不连续现象,而这种情况在D、E组中未被观察到。Masson-fontana染色显示,在bAlb/c雌鼠中均未见明显色素沉着,A、b、C、G组黑色素颗粒计数差异无统计学意义(h=7.77,P=0.051);而在C57bl/6jNifdc雌鼠中,E、f组表皮和真皮内均有较为明显的色素沉着,D、E、f、h组黑色素颗粒计数差异有统计学意义(h=17.61,Pb、C、G组胶原百分比差异无统计学意义(h=7.26,P=0.064);而E、f组则可观察到明显的纤维排列紊乱且结构松散,D、E、f、h组胶原百分比差异有统计学意义(h=8.65,P=0.034)。免疫组化结果显示,A、b、C、G组Il-1表达水平差异有统计学意义(h=17.86,Pf、h组Il-1表达水平差异有统计学意义(h=14.19,P=0.003),提示紫外线照射激发了小鼠皮肤的炎症反应。结论bAlb/c雌鼠并不适用于在本实验照射频率及时间范围内的黄褐斑模型建立,C57bl/6jNifdc雌鼠采用单次照射能量为7.59 j/cm^(2)、5 d/周的照射频率持续4周,可以获得稳定且具有一定色素沉着量的黄褐斑动物模型,并至少维持2周。

基于青藏铁路楚玛尔河试验段10年（2003～2013）的地温监测资料，对青藏铁路4种典型路基结构的长期热状况进行了对比分析．结果表明，不同路基结构的长期热状况表现出较大的差异．普通路基与块石基底路基地温场存在明显的不对称分布，表明以上两种路基结构不利于路基的长期热稳定．但块石护坡路基与u型块石路基的地温场分布则表现出了较好的对称性．尽管块石护坡路基下浅层冻土地温存在一定的降温过程，但深层多年冻土却呈现出缓慢升温趋势，显示u型块石路基的热稳定性要优于块石护坡路基．被监测的4种路基结构中，u型块石路基在降低多年冻土温度与提高路基地温场对称性方面表现出了最佳的长期效应．基于青藏铁路10年的监测结果，充分肯定了主动冷却路基设计思路在保护冻土路基长期热稳定性方面的有效性，同时采用冷却路基技术的青藏铁路也达到了时速100kmh-1的设计要求．尽管如此，由于坡向效应所导致的路基左右路肩下的热差异存在于所有监测的路基结构中，但不同结构的热差异幅度不同，并将可能导致路基发生潜在的非均匀性沉降变形，因此需要在后续的维护工程中进行调整．
