红壤侵蚀区优良水土保持草本植物的选择及评价

中国化学会第四届有机化学学术会议

作者： BIAN, Zhan-Xi wang, yan-Xue zhao, Hai-Ying (College of Chemistry and Chemical Engineering, Inner Mongolia University, Huhhot 010021)

＜正＞The development of practical technology for the preparation of cyanohydrins, α,β-unsaturated nitriles and β-aminoalcohols from readily available carbonyl compounds is an important area in organic chemistry. One straightforward method for synthesizing such compounds makes use of cyanohydrin trimethylsilyl ethers, which are generally prepared by the addition of trimethylsilyl cyanide （TMSCN） to carbonyl compounds in the presence of catalysts commonly used in asymmetry synthesis.

汽车产品价格影响因素分析和定价方法的研究,对于企业分析汽车市场和进行战略决策具有十分重要的意义。文章首先基于中国汽车市场的大数据,对影响中国汽车价格的因素及其特性进行了研究和分析,报告了目前国内汽车市场关于汽车定价杂乱无章的现状,然后通过采用灰色关联度分析的方法,展开对显著影响因素进行选择的调查,反映了汽车定价过程中缺乏有效模型的问题,进而构建了基于多因素灰色GM(1,N)模型的汽车产品定价模型,提出了汽车产品定价方法步骤,为国内汽车市场找到合适可行的模型以及定价策略。实证研究表明,该方法能够利用较少的数据得到有效的数学模型,与特征价格指数法相比,它具有较高拟合优度。最后对国内汽车市场汽车定价的管理提出了切实可行的政策建议,以期实现规范化管理中国汽车市场汽车定价的目的。

The coronavirus disease 2019（COVID-19） outbreak caused by the severe acute respiratory syndrome coronavirus-2（SARS-CoV-2） developed into a global health emergency. Systemic microthrombus caused by SARS-CoV-2 infection is a common complication in patients with COVID-19. Cardiac microthrombosis as a complication of SARS-CoV-2 infection is the primary cause of cardiac injury and death in patietns with severe COVID-19. In this study, we performed single-cell sequencing analysis of the right ventricular free wall tissue from healthy donors,patients who died during the hypercoagulable period of characteristic coagulation abnormality（CAC）, and patients who died during the fibrinolytic period of CAC. We collected 61,187 cells enriched in 24 immune cell subsets and 13 cardiac-resident cell subsets. We found that in the course of SARS-CoV-2 infected heart microthrombus, MYO1EhighRASGEF1Bhighmonocyte-derived macrophages promoted hyperactivation of the immune system and initiated the extrinsic coagulation pathway by activating chemokines CCL3, CCL5. This series of events is the main cause of cardiac microthrombi following SARS-CoV-2 infection. In a SARS-CoV-2 infected heart microthrombus, excessive immune activation is accompanied by an increase in cellular iron content, which in turn promotes oxidative stress and intensifies intercellular competition. This induces cells to alter their metabolic environment, resulting in increased sugar uptake via the glycosaminoglycan synthesis pathway. In addition, high levels of reactive oxygen species generated by elevated iron levels promote increased endogenous malondialdehyde synthesis in a subpopulation of cardiac endothelial cells. This exacerbates endothelial cell dysfunction and exacerbates the coagulopathy process.
