The unprecedented globalization of trade, travel, climate change, protectionism, and geopolitical populism, as well as pandemic health threats are no longer issues for a single nation. In the field of public health, China's Belt and Road Initiative (BRI) offers immense opportunities for partnership and collective actions involving multiple countries to combat globalization-linked infectious and/or chronic diseases, emerging pandemics, and outbreaks of potential threats to both laboratory information management systems and health information management. The national and global health challenges have increasingly proved that economic prosperity cannot be achieved when huge knowledge and capacity gaps exist in health systems. There is thus a need for public health initiatives aimed at strengthening the health systems beyond sovereign borders to influence global geo-economics. We highlight situational insights that offer approaches and strategies for increasing public health investment and capacity development in the countries along the Belt and Road, enhancing public and global health cooperation alongside participation in disease control and elimination, promoting public health governance and data sharing for pandemic threats, and building shared values and benefits in public health through Sino-African cooperation and the BRI. Our approach also examines the values of the China's BRI in relation to public health, projections and initiatives for increasing new investment and development capacity in public health systems, and enhanced public and global health cooperation and participation toward the BRI's framework and scope.

For industrial structure upgrading and modern service industry developing, China will need a large number of high-quality talents to contribute to new industrialization. China's higher education is important for cultivating high-quality, multi-skilled and well-trained talents. "What Knowledge is of most Worth?" that raised by Herbert Spencer is one of the most typical questions for education. After investigation, this study researches 2 questions based on China's huge demand of well-trained, high-skilled, and application-oriented talents under current economic development: 1) "What Knowledge is of most Worth?" Practical Scientific Knowledge. 2) The guidance on the education practice. The essay demonstrates the challenges and provides constructive suggestions including reform education curriculum, strengthen faculty and enhance university-enterprise cooperation which is multi-win for undergraduates, universities and enterprises. Based on the university-enterprise cooperation practice with company M, the experiences are summarized and the research results can be popularized.

A series of mono- and di-Schiff bases formed between benzil dihydrazone {BDH; systematic name: (1Z)-[(2E)-2-hydrazinylidene-1,2-diphenylethylidene]hydrazine} and three isomeric chlorobenzaldehydes were designed and synthesized to be used as model compounds to help to explain the reaction mechanisms for the formation of Schiff bases. These compounds are 1-(2-chlorobenzylidene)-2-{2-[2-(2-chlorobenzylidene)hydrazin-1-ylidene]-1,2-diphenylethylidene}hydrazine (BDHOCB), and the 3-chloro (BDHMCB) and 4-chloro (BDHPCB) analogues, all having the formula C28H20Cl2N4. Surprisingly, only di-Schiff bases were obtained; our attempts to push the reaction in favour of the mono-Schiff bases all failed. Density functional theory (DFT) calculations were performed to explain the trend in the experimental results. In the case of the systems studied, the type of Schiff base produced exhibits a clear dependence on the HOMO-LUMO energy gaps (ΔE(HOMO-LUMO)), i.e. the product is mainly governed by its stability. The compounds were characterized by single-crystal X-ray diffractometry, elemental analysis, melting point, (1)H NMR and (13)C NMR spectroscopy. The structural features of the three new Schiff bases are similar. For instance, they have the same chemical formula, all the molecules have a symmetrical double helix structure, with each Ph-C=N-N=C-Ph arm exhibiting an anti conformation, and their supramolecular interactions include intermolecular π-π and weak C-H...π stacking interactions. The crystal systems are different, however, viz. triclinic (space group P1¯) for BDHPCB, monoclinic (space group P2(1)/n) for BDHOCB and orthorhombic (space group Pnna) for BDHMCB.

Objectives: According to the swift development of talent ecosystem in Tobacco Industry, talent ecosystem is gradually becoming the most important energy in global competition. This research focuses on the development of talent employment quality in the process of improving the quality of organizational talents and talent ecosystem in Tobacco Industry. In view of the problems of employment quality development in China, a reasonable structure for the employment quality development in Tobacco Industryshould be constructed to realize the green and healthy development of the talent ecosystem.
