The impact of social and institutional changes on land resource use is an important component of the driving force of land use/cover changes. This paper primarily studies the characteristics and impacts of social and institutional changes on the use of land resources in China since the 1950s, which have played an important role in land use and land cover changes, but have not been studied enough by Chinese researchers in this field. Through discussion of the relation between social institution changes, changes of land resource management institutions and their impact on the changes of land resources, we identify and discuss the close connection between macro social ideology, institution and policy changes, and land use/cover changes in the context of China over the last 50 years, and establish the explanation and framework to illustrate the relationships and the phenomena.

Acarbose and voglibose are the most widely used diabetes drugs as glycosidase inhibitors. In this study, the use of these two inhibitors significantly increased the content of starch in large intestine, and altered the concentration of short-chain fatty acids (SCFAs) by affecting the intestinal microbiota. However, there are some differences in the intestinal microbiome of the two groups of mice, mainly in bacteria such as Bacteroidaceae bacteroides and Desulfovibrionaceae desulfovibrio. The productions of acetate and propionate in caecum in voglibose group were significantly higher than those in acarbose group and two kinds of glycosidase inhibitors were close in the production of butyrate in caecum. The Tax4Fun analysis based on Kyoto Encyclopedia of Genes and Genomes (KEGG) data indicated that different productions of acetate and propionate between acarbose group and voglibose group may be related to 2-oxoisovalerate dehydrogenase and pyruvate oxidase. In addition, in-vitro experiments suggested that voglibose had less effect on epithelial cells than acarbose after direct stimulation. According to the recent researches of SCFAs produced by intestinal microbiota, our comparative study shown higher concentration of these beneficial fatty acids in the lumen of voglibose-treated mice, which implied a lower level of inflammation.
