Coal consumption in China has been almost equal to the consumption of all other countries since 2011, and influenced not only global climate change but also domestic air pollution control, energy production and consumption revolution. Coal consumption is closely related to China's whole economy, and its cap control should be based on comprehensive understanding of different economic agents' interactions. Therefore, this study uses the input-output model to identify key relationships to be adjusted which have their significant direct and indirect effects on coal consumption. We find that fixed capital formation in construction having a significant indirect impact on coal consumption in all main coal-intensive sectors, and most of the important production relationships in a sector involve inputs of basic raw materials or fuel, such as building materials in construction. From the perspective of fine structure adjustment to control coal effectively, some non-basic inputs need massive restrictions, such as substantially reducing pesticide and fertilizer application in agriculture, and construction expansion should be limited to a rational growth through reducing short-lived buildings, constraining low-level redundant construction of roads and buildings, and minimizing the vacancy rate and incremental construction area. Moreover, export of coke, chemicals, and chemical products should be discouraged from the perspective of coal control, and urban households should consume daily chemical and pharmaceutical products more rationally.

The thesis is designed to, in a systematic way, sum up models and characteristics of typical international city clusters. Focusing on institution, mechanism, infrastructures and transport service of transportation in city clusters, it considers situation and demands for transportation in China’s city clusters, studies how transportation in China’s cities can learn from that in typical international city clusters, thus providing policy guidance and technical support to promote rational development in China’s city clusters and implement the new urbanization strategy in China.

Urban transport is a key support for urban economic and social development whose development is accompanied by the rapid and diversified development of cities. This study aims at systematically sorting out the process, pattern and goal of international typical urban transport development, summarizing its main development characteristics, and selecting index from 6 aspects such as supportability, maneuverability, safety, economy, sustainability and innovation etc. to analyze the development situation of urban transport in China and to compare it with international leading development level so as to identify the main difference, and to provide policy suggestions on healthy and sustainable development of urban transport in China.

The goal is to minimize the sum of operating cost and passengers’ travel cost, and establish an optimized combinational scheduling model of Bus Rapid Transit (BRT) combined with regular bus, express bus and shuttle bus. A mixed genetic algorithm based on tabu search algorithm (GA-TS) has been designed after analyzing the fundamental principle of genetic algorithm (GA) and tabu search (TS). A case study has been carried out on the combinational scheduling optimization of a selecting BRT line. By adopting the combinational scheduling model, 5.24% of the total system cost can be saved, which is quite prominent. The mixed genetic algorithm based on GA-TS can optimize the BRT scheduling system, shorten the turnaround time of operating BRT vehicles, effectively reduce the total system cost of BRT and improve decision-making efficiency and service quality.

Urban public transport is the basic and guiding industry for the cities development. And it is also important livelihood projects. In this paper, the main problems of urban public transport development are analyzed, and the strategic measures are proposed for the problems to promote the sustainable development of public transport. This paper aims to provide decision-making reference for urban management department.

The application of clean energy vehicles in urban transport affects not only the operational performance of the bus system but also the technology development for mobile industry, the energy consumption and emission level and the facility over its lifetime. With the survey data from 4cities in China (Jinan, Shanghai, Shenzhen and Chengdu), this article clarifies the policy environment and technology status, makes a policy assessment for the policies on promoting clean vehicles in China, analyzes the effectiveness of emission reduction cost and benefits, and proposes policy recommendations for promoting clean energy vehicles in place of the conventional vehicles in Chinese cities.

To explore the levels of adiponectin (APN), interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in first episode drug naїve schizophrenics and further examine the role of adipocytokines in schizophrenia.Ninety-six normal weight schizophrenics and 22 overweight/obese ones from First Affiliated Hospital, Zhengzhou University and 60 healthy controls were enrolled. Serum levels of IL-1β, IL-6, TNF-α and APN were measured with enzyme linked immunosorbent assay (ELISA).Serum levels of IL-1β, IL-6 and TNF-α in normal weight schizophrenics (54 ± 13, 34 ± 12, 48 ± 18) pg/ml and overweight/obese schizophrenics (71 ± 21, 40 ± 12, 53 ± 18) pg/ml were significantly higher than those in the controls (23 ± 16, 16 ± 7, 32 ± 15) pg/ml (P0.05). Serum levels of IL-1β and IL-6 in overweight/obese schizophrenics were significantly higher than those in normal weight schizophrenics (P0.05). Serum level of adiponectin in normal weight schizophrenics was significantly higher than that in control group [(12 ± 4) vs (9 ± 4) pg/ml, P0.05].The serum levels of APN, IL-1β, IL-6 and TNF-α increase in first episode drug naїve schizophrenics. It suggests that an inflammatory response mediated by adipocytokines. APN may play a pro-inflammatory role in schizophrenia.
