Two possible reaction mechanisms of VS^＋（^3∑^-, 1^Г） with CO in the gas phase have been studied by using B3LYP/TZVP and CCSD（T）/6-311＋G （3df, 3pd） methods： the O/S exchange reaction （VS^＋＋CO→VO^＋＋CS） and the S-transfer reaction （VS^＋＋ CO → V^＋＋ COS）. The two reactions proceed via two-step and one-step mechanism, respectively. The barriers of the triplet and singlet PESs are 30.6 and 50.9 kcal/mol, respectively, for O/S exchange reaction and 7.3 and 50.2 kcal/mol, respectively, for the S-transfer reaction. The results indicate that the triplet ground state reaction is more favorable, and the S-transfer reaction is more favorable than the O/S exchange reaction, which is in good agreement with the experimental observation.

Two possible reactions of NbS＋（3∑^-, 1Г） with CO in the gas phase have been studied by using B3LYP and CCSD（T） methods： the O/S exchange reaction （NbS^＋＋ CO → NbO^＋＋ CS） and the S-transfer reaction （NbS＋＋ CO → Nb^＋＋ COS）. The two reactions have a one-step mechanism. The barriers of the O/S exchange reaction on the triplet and singlet surfaces are 51.2 and 52.4 kcal/mol, respectively, and the barriers of the S-transfer reaction are 58.3 and 78.0 kcal/mol, respectively. The results indicate that the Stransfer and the O/S exchange reaction of the 3∑^- ground state of NbS＋ are competing, but, for the S-transfer reaction, the 1F exited state is more reactive. The differences between the reactions of NbS＋（3∑^_, 1Г） and VS＋（3∑^_, 1Г） are discussed.

Background Evidence showed that both myocardium and blood vessels were damaged in dilated cardiomyopathy （DCM）. However, the changes in arterial compliance, serum cytokines and circulating endothelial progenitor cells （EPC）, and their correlations remain unknown. Methods Sixty-five DCM patients and 49 healthy volunteers were studied. Both large artery compliance （C1） and small artery compliance （C2） were measured with the CVProfUor DO-2020. Quantitative enzyme-linked immunosorbent assays （EliSAs） were used to measure the levels of vascular endothelial growth factor-A （VEGF-A） and VEGF receptor 2 （VEGF-R2）. Circulating EPC was assessed by EPC colony-forming assays and flow cytometry （CD133^＋/CD34^＋cells）. Phagocytized Dil-acLDL and binded FITC-UEA-I were used to analyze endothelial lineage marker expression by immunofluorescence. Results Although C2 was markedly lower in DCM patients than in control group （（3.8±1.8） ml/mmHg × 100 vs （5.0±2.2） ml/mmHg × 100, P〈0.0001）, there was no statistically significant difference in C1 between the two groups （P〉0.05）. Levels of VEGF-A, the numbers of colony-forming units （CFU） and the fractions of EPC were obviously higher in DCM patients than in control group （（127.6±139.5） pg/ml vs （58.8±42.9） pg/ml, P〈0.0001; （2.5±1.5）% vs （0.5±0.3）%, P〈0.05; 23.5±12.8 vs 10.8±7.4, P〈0.01, respectively） and however, there was no significant difference in VEGF-R2 between two groups （P〉0.05）. LgVEGF-A was positively correlated with the number of EPC-CFU （r=-0.435; P〈0.05） and inversely correlated with C2 （r=-0.543; P〈0.001） in DCM patients. Conclusions The reduction of C2, a sensitive marker reflecting endothelial dysfunction, was observed in DCM patients and closely related to the increase in serum VEGF-A.

将非制度化的伦理道德渗透到制度化的公共政策中去,是当前世界各国道德治理的一种路径选择。坚持公共政策合理的价值导向是实现社会道德治理的重要手段。新加坡社会公共政策以共同价值观为导引,通过住房政策、中央公积金制度和赡养父母法令等,激励或约束社会成员履行应尽的责任和义务,有利于公民践行社会道德,并能够使良好的社会道德风尚在代际之间传递,形成较好的社会道德治理环境。新加坡社会公共政策的道德治理经验,对建设中国特色社会主义道德具有积极的启示。
