Abstract

Bioassay-guided fractionation of the petroleum ether, chloroform and EtOAc extracts of the stems of Ficus auriculata led to the isolation of five new 12-membered lactones (3R,4R)-4-hydroxy-de-O-methyllasiodiplodin (1), 6-oxolasiodiplodin (2) and ficusines A-C (3-5), together with three known related analogues (6-8). The structures of the new compounds were elucidated by comprehensive spectroscopic data. The absolute configurations of 3 and 8 were established by single crystal X-ray diffraction analysis. Compounds 3-5 represent the first 12-membered lactones with a quinone ring unit. Compounds 6 and 7 exhibited significant proliferation function of primary osteoblasts (OBs) in vitro. Especially, the promotion rate of 6 reached 151.55±1.34% (P0.001) at the concentration of 100 μM.

Abstract

Low-carbon energy and constraints of resources and environment will increasingly become two important factors inhibiting China's economic development in the future. According to the relationship and coordinating mechanisms among energy consumption, carbon dioxide emission and economic development, This paper establishes the two-dimensions evaluation indicating system based on balanced. Use data development analysis, through the fact data of some typical provinces in 2009, we make a comprehensive assessment of its historic coordination, analyze the degree of coordination and the reasons for the contradiction, strive to source the dialectical unity from similarities and differences, and finally proposed some political ideas and recommendations on promoting China's future coordinating development among economy, energy, and environmental.

Abstract

This paper analyzed the process of the LCD and the industrial structure in the typical countries to reveal the Causality Relationship between LCD and Industrial Structure. First, most of the developed countries industry have experienced the high-carbon period. When the economy evolved to a certain extent, the base level of the LCD increased. And In developing countries, especially in China, the tertiary industry shared a much smaller part in the whole economy system comparing with that of the developed countries. Then, Based on the output of regression analysis, the appreciable correlation between the LCD and the industrial structure was found. Finally, the results of Granger causality tests lead to the conclusion that the tertiary industry of China is the Granger cause of the LCD within 98 percent confidence intervals. It suggests that the industry structure should be adjusted before the LCD, especially the development of tertiary industry.
