It's very important to establish an evaluation system to match international standards for improving the medical education quality in China.This article reviews the global profile of evaluation process for higher education,and compares it with the current status in China.It introduces the characteristics and experiences from overseas as references to optimize our medical education evaluation system.

Introduced the the national experimental cell resource sharing platform construction process and its function.Summerize the content,experience and outcome of the cell resource physical platform and information services since it launched,analysed the problems existing in the current platform running,and proposed solutions to address these issues,pointed out the next step in the development.

In Scientific Research Institutions,it has great significance of the S&T resources archiving and sharing to promote the deepening reform of S&T system and realize the great leap-forward development of S&T innovation.In this paper,we conduct empirical analysis on the conditions of S&T resources archiving and sharing in a Medical Organization in Beijing.The results show that the S&T resources archiving and sharing in Medical Organization have achieved initial success,however,the achievements are not ideal and the waste and shortage of S&T resources still coexisted.In view of the deficiencies of the idea,system,laws and regulations of S&T resources archiving and sharing,this paper puts forward corresponding countermeasures and suggestions.

Pyruvate dehydrogenase E1 component subunit beta-1 (PDHB-1) is a gene encoding the β-subunit of pyruvate dehydrogenase complex, which plays an important role in fruit acid accumulation. The aim of this study was to investigate the evolution characteristics of apple PDHB-1 family and its expression in apples with different acid contents. Bioinformatics analysis was performed using databases including NCBI, Pfam and software including ClustalX, MEGA, and TBtools. By combining titratable acid content determination and quantitative real-time PCR (qRT-PCR), the expression of this family genes in the peel and pulp of apple 'Asda' and 'Chengji No.1' with different acid content were obtained, respectively. The family members were mainly located in chloroplast, cytoplasm and mitochondria. α-helix and random coil were the main factors for the formation of secondary structure in this family. Tissue-specific expression profiles showed that the expression of most members were higher in fruit than in other tissues. qRT-PCR results showed that the expression profile of most members was consistent with the profile of titratable acid contents. In the peel, the expression levels of 14 members in 'Asda' apples with high acid content were significantly higher than that in 'Chengji No.1' apples with low acid content, where the expression difference of MdPDHB1-15 was the most significant. In the pulp, the expression levels of 17 members in 'Asda' apples were significantly higher than that in 'Chengji No.1' apples, where MdPDHB1-01 was the most highly expressed. It was predicted that PDHB-1 gene family in apple plays an important role in the regulation of fruit acidity.
