Objective: To investigate the main components and potential mechanism of Shuxuening Injection(SXNI) in the treatment of myocardial ischemia-reperfusion injury(MIRI) through network pharmacology and in vivo research. Methods: The Traditional Chinese Medicine Systems Pharmacology(TCMSP) and Pharm Mapper databases were used to extract and evaluate the effective components of Ginkgo biloba leaves, the main component of SXNI. The Online Mendelian Inheritance in Man(OMIM) and Gene Cards databases were searched for disease targets and obtain the drug target and disease target intersections. The active ingredient-target network was built using Cytoscape 3.9.1 software. The STRING database, Metascape online platform, and R language were used to obtain the key targets and signaling pathways of the anti-MIRI effects of SXNI. In order to verify the therapeutic effect of different concentrations of SXNI on MIRI in rats, 60 rats were first divided into 5 groups according to random number table method: the sham operation group, the model group, SXNI low-dose(3.68 mg/kg), medium-dose(7.35 mg/kg), and high-dose(14.7 mg/kg) groups, with 12 rats in each group. Then, another 60 rats were randomly divided into 5 groups: the sham operation group, the model group, SXNI group(14.7 mg/kg), SXNI+LY294002 group,and LY294002 group, with 12 rats in each group. The drug was then administered intraperitoneally at body weight for 14 days. The main biological processes were validated using in vivo testing. Evans blue/triphenyltetrazolium chloride(TTC) double staining, hematoxylin-eosin(HE) staining, terminal deoxynucleotidyl transferase d UTP nick end labeling(TUNEL) assay, enzyme-linked immunosorbent assay(ELISA), and Western blot analysis were used to investigate the efficacy and mechanism of SXNI in MIRI rats. Results: Eleven core targets and 30 Kyoto Encyclopedia of Genes and Genomes(KEGG) pathways were selected. Among these, the phosphoinositide 3-kinase(PI3K)/protein kinase B(AKT) pathway was

构建碳定价机制是发挥碳价格资源配置作用的关键。本文构建了包含显性碳定价政策(碳税和碳排放权交易市场)和隐性碳定价政策(绿色金融和政府负碳投资)的宏观经济分析框架,深入剖析碳定价机制的协同效应。研究发现,第一,减碳杠杆效应和经济产出效应是碳定价机制释放碳价格信号,是实现“双碳”约束下经济高质量发展的重要渠道。第二,以减排为核心的碳达峰依赖于“下调碳配额+开征碳税+扩大绿色金融规模+加强政府引导负碳投资”的政策框架;兼顾减排和固碳的碳中和需要“下调碳配额并完善碳排放权交易市场+一般性碳税税负+推动信贷结构低碳转型+扩大社会负碳投资规模”的政策框架。第三,碳定价政策协同要关注以下因素,一是适度调控碳配额并提升碳排放权交易市场的完备性;二是开征碳税作为碳排放权交易市场的替代性政策,初期以同类税负合并的方式开征并动态提升税负水平;三是逐步推动银行信贷结构低碳转型;四是推广负碳技术,通过政府引导、市场定价等方式提升社会资本参与度。本文系统性思考了碳定价机制顶层框架的构建,为我国实现经济绿色低碳转型发展提供了参考。

为进一步优化超音速分离线摆动喷管性能,通过数值计算分析了分离线处扩张比(ε)对超音速分离线摆动喷管流场的影响规律,并进行了试验验证。结果表明:相同ε下,随着摆动角度(θ)的增加,轴向推力系数(C_(fx))逐渐减小;ε取不同值时,相同θ下C_(fx)区别较大,在ε=1.68时C_(fx)达到最大值。相同ε下,随着θ的增加,偏转放大系数(K)先增加后减小,θ为1°~2°时,K值达到最大(K=2.5);不同ε下K区别较大,当ε≥1.46、θ为1°~8°时,K>1,ε=1.21时偏转效益受θ影响较大,K最小值小于1。数值仿真喷管羽流状态与地面试验一致,验证了仿真方法的有效性;分离线处压强由于模型误差存在一定偏差,摆动力矩由于分离线处压强的非均匀分布存在计算偏差。

时间洞察力是个体精准把控时间的品格。当前,西方学者对时间洞察力的概念化与研究均含糊不清,国内学者的客位化研究取向亦难以触及中国人时间洞察力的实质。文章以中国人的时间洞察力为切入点,采用基于深度访谈的扎根理论方法,运用访谈精英的取样策略,构建出中国人时间洞察力的三维结构模型。在中国人的时间洞察力中,过去、现在和未来是有机整合的,个体在心理时间的往返回荡中扫描而生成历史理性并用来指导实践,进而构建出一种可以克服“理想”与“现实”矛盾的人文时间。中国人的时间洞察力有一套极为独特的思考,认为历史会遵循某种规律(即“势”)而向前推进,掌握时机(时点)、把握火候(时距)并遵从规律(时序)便能因势利导获取成功。个人的生命时间虽然有限,但是主动参与群体共业可以创造出“超时间”的意义,继而创造其生命永恒不朽之价值。这种升华生命情感的超时间观,可能是疗愈现代时间病症的儒家养分。
