当前我国正处于社会转型时期,需要传承和弘扬中华优秀传统文化、坚定文化自信。中国传统义利观中的以义为先、以义谋利、义中取利、义利合一等论述,对于我国当今社会发展有着重要的现实价值,主要体现在:坚守以义为先,避免人际交往的失信化、利己化和功利化,是构建和谐人际关系的基础;信守义中谋利,既是企业和个人发展的前提,也有利于个人道德素质的提升和企业软实力的增强,推进社会的持续发展;遵循义中取利,能帮助人们树立合理的财富观;坚持义利合一,公利即为义,也就是在个人利益与集体利益发生矛盾时,以集体利益为首,促进健康群己观的形成。

碱性亮氨酸拉链(bZIP)是一类广泛存在真核生物中的转录因子家族,参与多种植物生长发育及生物和非生物胁迫的响应过程,对下游许多基因的表达具有强烈调控作用。为了解芥菜bZIP基因家族的基因结构,成员之间的相互关系以及在非生物胁迫下的反应机制。本研究利用生物信息学方法,从Brassica Database (BRAD)数据库下载的芥菜基因组中鉴定到81个BjubZIP基因,其中34.57%的基因缺乏内含子,59.26%的BjubZIP等电点小于7,表明芥菜中有超过一半的bZIP蛋白为酸性蛋白,亚细胞定位预测所有的基因均位于细胞核。将81个BjubZIP进一步分为与拟南芥基因相对应的6个亚群,同一亚群的motif数量和基因结构高度相似。利用公共数据库中的芥菜转录组数据,对BjubZIP基因家族在干旱和高温胁迫下的表达分析,发现A亚群基因中的BjubZIP02、BjubZIP21、BjubZIP28、BjubZIP38、BjubZIP50、Bjub ZIP62、BjubZIP59在高温和干旱胁迫下均处于上调状态,推测芥菜中的这7个基因可能与拟南芥A亚群基因的功能相似,参与了在非生物胁迫下相应的生理过程。本研究结果可为今后芥菜bZIP家族成员的基因克隆和在胁迫反应中的功能研究提供参考。

To better understand the community patterns mediated by connectivity in artificial reefs of coastal areas, it is necessary to understand the distribution and coexistence of organisms with artificial reefs area and adjacent waters. This study was conducted to examine main catches assemblages collected by trawls in Haizhou Bay,which included five habitats: the artificial reef area(AR), aquaculture area(AA), natural area(NA), estuary area(EA) and comprehensive effect area(CEA). The result shows that the total abundances of species in the five habitats were highly different(univariate PERMANOVA: P = 0.001, n = 24), but some species were also unique in their habitat(e.g. Scapharca subcrenata and Glossaulax didyma in AA). The body size distribution of specific species between habitats are different. For Collichthys lucidus, their body size in AR(14.63 cm ± 1.64 cm) and EA(14.3 cm ± 0.85 cm) is higher than that in NA(10.65 cm ± 1.64 cm), CEA(11.28 cm ± 1.85 cm) and AA(12.1 cm ±0.43 cm), which indicates the potential connection from AR to EA mediated by their adult population. We concluded that artificial reefs in AR can be considered key components that have the ability to support species assemblages in adjacent habitats. This study has implications for the conservation and monitoring of species assemblages in coastal areas in terms of that artificial reefs can be applied in different stages of habitat protection implementation and in different combinations of scenarios.

α-N-acetylgalactosaminidase (αNAGA) can convert group A human red blood cells (RBCs) to group O. One novel αNAGA gene was cloned by PCR from Elizabethkingia meningosepticum isolated from a domestic clinical sample. Pure recombinant αNAGA was obtained by genetic engineering and protein purification with a calculated molecule of 49.6 kD. αNAGA was selective for terminal α-N-acetylgalacto-samine residue with a high specific activity. αNAGA could completely remove A antigens of 1 U (about 100 mL) group A1 or A2 RBCs in 1 h at pH 6.8 and 25℃ with a consumption of 1.5 or 0.4 mg recombinant enzyme. Enzyme-converted group A RBCs did not agglutinate after being mixed with monoclonal anti-A or sera of groups A,B,AB and O. Other blood group antigens except ABO had no change. FCM analy-sis showed that A antigens and A1 antigens disappeared while H antigens increased. It indicated that αNAGA successfully converted human blood group A RBCs to universally transfusable group O RBCs without the risk of ABO-incompatible transfusion reactions. This αNAGA was suitable for producing universal RBCs to increase clinical transfusion safety,improve the RBCs supply,and to decrease transfusion cost and support transfusion service in case of emergency.

Ferroptosis, a unique type of non-apoptotic cell death resulting from iron-dependent lipid peroxidation, has a potential physiological function in tumor suppression, but its underlying mechanisms have not been fully elucidated. Here, we report that the long non-coding RNA(lncRNA) LncFASA increases the susceptibility of triple-negative breast cancer(TNBC) to ferroptosis. As a tumor suppressor, LncFASA drives the formation of droplets containing peroxiredoxin1(PRDX1), a member of the peroxidase family, resulting in the accumulation of lipid peroxidation via the SLC7A11-GPX4 axis. Mechanistically, LncFASA directly binds to the Ahpc-TSA domain of PRDX1, inhibiting its peroxidase activity by driving liquid-liquid phase separation, which disrupts intracellular ROS homeostasis. Notably, high LncFASA expression indicates favorable overall survival in individuals with breast cancer, and LncFASA impairs the growth of breast xenograft tumors by modulating ferroptosis. Together, our findings illustrate the crucial role of this lncRNA in ferroptosis-mediated cancer development and provide new insights into therapeutic strategies for breast cancer.

党内法规保留是将法律保留相关原理引入党内法规制度建设中形成的有关党内事务制定权配置的制度。在中国特色社会主义法治体系的法治背景下,党内法规保留应以法治规范体系作为制度建构的基本视角。基于与法律保留的功能比较,党内法规保留具有统制、区分、整合、保障等功能。在法治规范体系视域下,当前党内法规保留制度存在明显结构缺陷。可以从重塑党内法规保留的结构理念、重新阐释《中国共产党党内法规制定条例》第四条第一款的保留对象、建立相对保留制度、单列党章保留事项、对中央党内法规绝对保留事项进行内涵解读等方面进行结构重塑与完善。此外,在党内法规保留的保留标准上,应确立面向从严治党的重要事项保留标准。

通过背散射电子衍射(EBSD)、XRD、拉伸试验、硬度测试、热膨胀测试、磁性能测试等研究了20%~90%不同冷轧压下率对因瓦合金显微组织、力学性能、热膨胀性能、饱和磁化强度和织构演变的影响。结果表明,随着冷轧压下率的增加,固溶态等轴晶粒通过位错滑移发生变形,合金被逐渐压扁拉长形成了特定的取向,导致合金的强度和硬度提高,而塑性快速下降,90%压下率时合金抗拉强度为777 MPa,而伸长率则只有5%。当冷轧压下率未超过80%时,合金的在20~100℃的平均线膨胀系数和饱和磁化强度呈现先减小后增大趋势,在60%压下率时取得最小值。合金中{110}黄铜织构,{112}S型织构强度随变形程度的提高而增大,当冷轧压下率达到80%时合金中形成了强烈的织构。
