Recent plant development studies have identified regulatory pathways for epidermal cell differentiation in Arabidopsis thafiana. Interestingly, some of such pathways contain transcriptional networks with a common structure in which the homeobox gene GLABLA2 （GL2） is downstream of the transactivation complex consisting of MYB, bHLH, and WD40 proteins. Here, we review the role of GL2 as an output device of the conserved network, and update the knowledge of epidermal cell differentiation pathways downstream of GL2. Despite the consistent position of GL2 within the network, its role in epidermal tissues varies; in the root epidermis, GL2 promotes non-hair cell differentiation after cell pattern formation, whereas inthe leaf epidermis, it is likely to be involved in both pattern formation and differentiation of trichomes. GL2 expression levels act as quantitative factors for initiation of cell differentiation in the root and leaf epidermis; the quantity of hairless cells in non-root hair cell files is reduced by g12 mutations in a semi-dominant manner, and entopically additive expression of GL2 and a heterozygous g12 mutation increase and decrease the number of trichomes, respectively. Although few direct target genes have been identified, evidence from genetic and expression analyses suggests that GL2 directly regulates genes with various hierarchies in epidermal cell differentiation pathways.

The gamma-ray burst （GRB） mission Swift has made a much deeper GRB survey than any previous one. I present a systematical comparison between GRB samples detected with pre-Swift missions and those from Swift, in order to investigate whether they show any statistical difference. Our Swift GRB sample includes the bursts detected by Swift/BAT before 2007 September. With both flux-limited surveys and redshift-known GRB samples, I show that, apparently, the observed distributions of the redshifts, T90, and log N- log P are significantly different, but not for the spectral hardness ratio, fluence and Eiso. The redshifts of the Swift GRB sample are statistically larger than those of pre-Swift GRBs, with a mean of 1.95±0.17 compared to ～ 1 for pre-Swift GRBs. The cosmological effect on the observables is thus considerable. This effect on the spectral hardness ratio, fluence and Eiso is cancelled out, and the distributions of these quantities indeed do not show significant differences between the Swift and pre-Sw/ft GRBs. Taking this effect into account, I found that the corrected distributions of T90 for long GRBs and log N - log P observed with Swift/BAT are also consistent with those observed with CGRO/BATSE. These results indicate that the Swift and pre-Swift GRBs are from the same population.

凌星法是研究系外行星大气的重要方法之一.在地面上对系外行星大气进行观测时,传统凌星法通常在目标星之外同时观测一颗或多颗参考星,利用较差光谱法并结合高斯过程回归,以同步监测并线性地消除凌星光变曲线内由于地球大气和仪器效应产生的系统噪声.尝试了一种新方法,即不使用较差光谱法,而是将参考星的光变曲线作为高斯过程的相关量来探索光变曲线中的系统噪声,该方法允许在目标星光变曲线和同时记录的时间序列间进行更灵活的非线性映射,以此详尽地探索凌星信号中存在的系统噪声.更进一步,还测试了没有参考星的情况,以模拟视场中无参考星的行星系统的凌星观测.对此进行了试验和研究,将此方法应用于一次热木星WASP-69b的凌星光谱数据中.研究发现,对于WASP-69b的这次凌星数据,新方法在使用参考星时获得的白光凌星深度精度优于传统方法,获得的分光光变曲线残差普遍小于传统方法得到的残差,而在没有参考星情况下,利用已知的凌星中心时间仍可以得出可接受的结果.更多针对凌星数据的测试,可进一步验证新方法的优势和适用性.

Pig pancreas ferritin（PPF） was purified by ultra-centrifugation, ion-exchange chromatography, and native gradient polyacrylamide gel electrophoresis（PAGENG）. Sodium dodecyl sulfate（SDS）-PAGE indicates that PPF consists of two subunit types, namely, H（21000） and L（19000） subunits, and its core shows an average element composition of 1698 Fe3＋ and 179 phosphate molecules within the hollow shell, giving a 9.5：1 ratio of Fe3＋ to phosphate. An off line approach combining reversed-phase high-performance liquid chromatography（RP-HPLC） with matrix-assisted laser desorption ionization time of flight mass spectrometry（MALDI-TOF MS） made the decomposition of PPF shell into H and L subunits for the analysis of mass spectrometry（MS）, giving molecular weights of both H（21014.4） and L（18319.9） subunits. Both subunit types were further identified by an approach combining peptide mass fingerprint（PMF） with database search. A ratio of 1H to 2L subunits in PPF was determined by SDS-PAGE, RP-HPLC, and MALDI-TOF MS, respectively. It is well known that the non-covalent interaction of L-L or H-L subunits is stronger than that of H-H subunits in PPF, which may be further used to explain the unclear physiological function between H and L subunits in PPF.

目的分析乳腺癌术后接受调强放疗患者的临床特征和剂量学参数与放射性肺炎之间的相关性,为术后放疗计划的制定提供参考。方法回顾性分析2020年1月至2021年12月在同济大学附属第十人民医院接受术后放疗的乳腺癌患者的临床资料,收集患者的临床特征、患侧肺体积(ipsilateral lung volume,ILV)、平均肺剂量(mean lung dose,MLD)和体积剂量参数V5~V50,分析其与放射性肺炎的相关性。结果177例乳腺癌患者中75例发生放射性肺炎,其中1级占93.3%,2级占6.7%。单因素分析显示,双靶治疗、内乳区放疗、MLD、V13、V15、V20、V25、V30、V35、V40、V45、V50均与放射性肺炎发生有关(均P<0.05)。多因素分析发现,V35和V50均是放射性肺炎发生的独立危险因素(均P<0.05)。受试者工作特征曲线分析显示,以V35的20.27%作为截断值,其预测放射性肺炎的敏感度和特异度分别为42.7%和77.5%,AUC为0.619;以V50的3.155%作为截断值,其预测放射性肺炎的敏感度和特异度分别为50.7%和75.5%,AUC为0.626。结论V35和V50均是放射性肺炎发生的独立危险因素,降低高剂量区V35和V50对减少放射性肺炎的发生有重要意义。
