It has been shown that microRNA-146 (miR-146) is involved in the regulation of immune and inflammatory responses. The present study explored the protective effects of miR-146 overexpression on lipopolysaccharide (LPS)-mediated injury in A549 and H1975 cells. In this study, A549 and H1975 cells were transfected with miR-146 mimic or inhibitor, and then were subjected with LPS. Thereafter, cell viability, colony formation capacity, apoptosis, the release of proinflammatory factors, Sirt1 expression, and the expression of NF-jB and Notch pathway proteins were respectively assessed. As a result, miR- 146 overexpression exerted protective functions on LPS-damaged A549 and H1975 cells, as evidenced by the increases in cell viability and colony number, the decrease in apoptotic cell rate, as well as the down-regulations of IL-1, IL-6, and TNF- a.

  • Diary of the Deputy Executive of Huabei Oilfield
    Chapter 20 Diary of the Deputy Executive of Huabei Oilfield 1 My Appointment In August 1975, 3269 Drilling Crew of Dagang Oilfield’s Second Drilling Company drilled the Ren-4 well, which produced 1,000 tons of oil per day. The following month, Petroleum Minister Kang Shi’en ordered the formation of the five-member Central Hebei Oil Campaign Leadership Group, which was led by Ren Chengyu, the deputy director of the Ministry of Petroleum’s Political Department. I was one of the members. In October, six days after National Day, the group led approximately 30 people from Dagang Oilfield straight to a wheat field, south of Renqiu Town, putting up shanties and cotton tents that served as headquarters for the oil campaign. A few days later, Director Ren asked me to lead a work group of four people within 3269 Drilling Crew, in addition to my usual task of attending decision-making meetings. I carried my bedding and lived in the drilling crew’s cotton tent. For more than a month, while taking part in all the work related to campaign planning, I also experienced first-hand the oil workers’ hardships and joys. Meanwhile, the campaign developed very fast, as 1,000-ton per day wells kept popping up. To strengthen leadership, the Ministry assigned Deputy Minister Zhang Wenbin in January 1976 to serve as commander and secretary of the Party Committee of Huabei Oil Campaign. Deputy Director Ren Chengyu was named deputy commander and deputy secretary of the Party Committee, in charge of political and ideological work. Deputy Minister Zhang had been dep- uty commander and deputy party secretary of Daqing Oil Campaign in 1960.

Green development is the hot spot of cold chain logistics today. +erefore, this paper converts carbon emission into carbon emission cost, comprehensively considers cargo damage, refrigeration, carbon emission, time window, and other factors, and establishes the optimization model of location of low-carbon cold chain logistics in the Beijing-Tianjin-Hebei metropolitan area. Aiming at the problems of the fish swarm algorithm, this paper makes full use of the fireworks algorithm and proposes an improved fish swarm algorithm on the basis of the fireworks algorithm. By introducing the explosion, Gaussian mutation, mapping and selection operations of the fireworks algorithm, the local search ability and diversity of artificial fish are enhanced. Finally, the modified algorithm is applied to optimize the model, and the results show that the location scheme of low-carbon cold chain logistics in Beijing-Tianjin-Hebei metropolitan area with the lowest total cost can be obtained by using fireworks-artificial fish swarm algorithm.

  • Digital Environmental Governance in China: Information Disclosure, Pollution Control, and Environmental Activism in the Yellow River Delta
    www.water-alternatives.org Volume 10 | Issue 3 Tan, J. and Eguavoen, I. 2017. Digital environmental governance in China: Information disclosure, pollution control, and environmental activism in the Yellow River Delta. Water Alternatives 10(3): 910-929 Digital Environmental Governance in China: Information Disclosure, Pollution Control, and Environmental Activism in the Yellow River Delta Jiaxin Tan Independent Researcher; Guangzhou, China; [email protected] Irit Eguavoen Center for Development Research, University of Bonn, Bonn, Germany; [email protected] ABSTRACT: The Chinese water bureaucracy increasingly utilises information and communications technology (ICT) in order to strengthen interaction with the population, which is severely affected by industrial pollution. Government webpages, mailboxes, and online interviews with officers have become prevalent tools for environmental governance, including information disclosure, and a virtual communication forum between the state and its citizens. The present study employs a mixed methods approach with a qualitative emphasis to explore the process of communication and interaction between government agencies and local residents in Dongying, Shandong Province. The results show that information disclosure of pollution data remains far from being transparent, despite the fact that the local government has implemented digital environmental governance, as encouraged by the central Chinese state. Internet technologies empower resource-poor environmental activists in Dongying to strengthen their social network and build communication with the authorities. The application of bureaucratic techniques, however, is key for them to enter the communication interface with government agencies in order to influence political decisions. Results suggest that local cadres tend to send mixed signals to activists and display wariness towards them. They also tend to take preventive measures to keep the situation under control when environmental disputes arise.

  • The Chinese State in Ming Society
    The Chinese State in Ming Society The Ming dynasty (1368–1644), a period of commercial expansion and cultural innovation, fashioned the relationship between the present-day state and society in China. In this unique collection of reworked and illustrated essays, one of the leading scholars of Chinese history re-examines this relationship and argues that, contrary to previous scholarship, which emphasized the heavy hand of the state, it was radical responses within society to changes in commercial relations and social networks that led to a stable but dynamic “constitution” during the Ming dynasty. This imaginative reconsideration of existing scholarship also includes two essays first published here and a substantial introduction, and will be fascinating reading for scholars and students interested in China’s development. Timothy Book is Principal of St. John’s College, University of British Colombia. Critical Asian Scholarship Edited by Mark Selden, Binghamton and Cornell Universities, USA The series is intended to showcase the most important individual contributions to scholarship in Asian Studies.

  • Information Extraction of Tourist Geological Resources Based on 3D Visualization Remote Sensing Image
    The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XLII-3, 2018 ISPRS TC III Mid-term Symposium “Developments, Technologies and Applications in Remote Sensing”, 7–10 May, Beijing, China INFORMATION EXTRACTION OF TOURIST GEOLOGICAL RESOURCES BASED ON 3D VISUALIZATION REMOTE SENSING IMAGE Wang Xulong Shandong Remote Sensing Center of Technology and Application, Jinan, China [email protected] Commission III, WG III/1 KEY WORDS: Remote sensing image, 3D visualization, Tourism geological resources, Information Extraction, Investigation ABSTRACT: Tourism geological resources are of high value in admiration, scientific research and universal education, which need to be protected and rationally utilized. In the past, most of the remote sensing investigations of tourism geological resources used two-dimensional remote sensing interpretation method, which made it difficult for some geological heritages to be interpreted and led to the omission of some information. This aim of this paper is to assess the value of a method using the three-dimensional visual remote sensing image to extract information of geological heritages. skyline software system is applied to fuse the 0.36m aerial images and 5m interval DEM to establish the digital earth model. Based on the three-dimensional shape, color tone, shadow, texture and other image features, the distribution of tourism geological resources in Shandong Province and the location of geological heritage sites were obtained, such as geological structure, DaiGu landform, granite landform, Volcanic landform, sandy landform, Waterscapes, etc. The results show that using this method for remote sensing interpretation is highly recognizable, making the interpretation more accurate and comprehensive. 1. INTRODUCTION features of the geological heritage displayed in the three- dimensional visualized remote sensing image, remote sensing Tourism geological resources are of high value in admiration, interpretation keys are established(Zhao, 2013).
