This study focuses on a national regional coordinated development strategy and adopts China Multi-Regional Computable General Equilibrium model to analyze the economic and social development, energy demand, and carbon emissions of the provinces during the 14th Five-Year Plan (FYP, 2021 2025) period based on the economic development and energy demand since the New Normal. The main conclusions are the following: 1) Under the guidance of the regional coordinated development strategy, 13 provinces/municipalities are expected to have a per capita gross domestic product (GDP) of more than US$15,000, and 16 provinces/municipalities will have a per capita GDP of US$10,000 15,000. All provincial economies are expected to achieve steady and rapid development by the end of the 14th FYP. 2) The total energy consumption of the provinces is expected to reach 5.45 Gtce (excluding Tibet) in 2025, and the average annual growth rate is approximately 1.5%. The growth of energy demand will remain in low speed. The key point of energy demand will gradually shift from the eastern to the middle area, while the proportion of energy use in the western provinces will remain stable, which is consistent with the economic development stage and regional coordinated development strategy. 3) The annual average carbon intensity (mainly considering carbon emissions from energy use) of the provinces will approximately with most provinces dropping by over 4.0%. The trend of a considerable decline in carbon intensity, as observed in recent years, is expected to continue.

In order to investigate the mode of action ofYimu Shenghuasan preparation in endometrial cells of dairy cows, the primary cultured endometrial cells in cows were isolated and the inflammatory models were made by lipopolysaccharide （LPS） induction. The inflammatory cells were treated with gradient concentration of herbal medicine preparation, Yimu Shenghuasan for 48 and 72 h. The expression of cytochrome P450 （CYP450） was detected by Western blot. The amounts of IgG and lgA in sera were also detected in the endometritis of dairy cows. The expression level of CYP450 in the endometrial cells of dairy cow was increased gradually, and the amounts of IgG, IgA were increased significantly as compared with those in the control group. The expression level of CYP450 in the inflammatory cells was increased significantly in the treatment of 2 000 μg mL^-1 of Yimu Shenghuasan after 48 h of treatment.
