ABSTRACT
Acute respiratory distress syndrome (ARDS) refers to acute diffuse lung injury caused by a variety of intrapulmonary and/or extrapulmonary factors such as infection and trauma. Uncontrolled inflammatory response is the main pathological feature. Different functional states of alveolar macrophages have different effects on inflammatory response. Transcription activating factor 3 (ATF3) is a fast response gene in the early stage of stress. In recent years, it has been found that ATF3 plays an important role in regulating the inflammatory response of ARDS by regulating the function of macrophages. This paper reviews the regulatory effects of ATF3 on alveolar macrophage polarization, autophagy and endoplasmic reticulum stress and its effects on the inflammatory process of ARDS, aiming to provide a new research direction for the prevention and treatment of ARDS.
ABSTRACT
High mobility group protein B1 (HMGB1), a highly conversed non-histone nucleoproteins with strong pro-inflammatory property, is one of the inflammatory mediator of the acute respiratory distress syndrome (ARDS). Numerous studies have confirmed that HMGB1 regulates ARDS by binding to receptor for advanced glycation end product (RAGE), Toll-like receptor (TLR) and etc. And it can significantly increase the mortality of ARDS. But the mechanism of HMGB1 release is still unclear. This study focuses on the HMGB1 release progress, which connected with Janus kinases/signal transducer and activator of transcription (JAK/STAT), nuclear factor-κB (NF-κB), Notch, inflammasome, tumor necrosis factor (TNF), mitogen-activated protein kinase (MAPK), reactive oxygen species (ROS), peroxisome proliferator-activated receptor (PPAR) and other signaling or dependent pathways in ARDS.
ABSTRACT
China has entered an aging society since 1999. By the end of 2017, the number of persons aged ≥60 years had increased to 240.90 million. At present, the average life expectancy of China’s population is 76.4 years, and the healthy life expectancy is around 68.7 years, which means that the elderly will be accompanied by disease for about 8 years. The main health problems of the elderly in China include increased prevalence of chronic diseases, increased prevalence of disability, insufficient attention to older persons’ mental health and area specific differences in the health level of the elderly. The disease status of the elderly cannot be ignored. Strengthening the medical services in western and rural areas, emphasizing the psychological and mental concern for the elderly, formulating unified health evaluation criteria, promoting a new model of medical and nursing care combination, establishing an elderly security system with equal responsibilities and rights, jointly managing under the cooperation of whole society and multi-dimensions to protect the health of the elderly are essential to the construction of an active ageing society in China and the realization of the strategic goal of healthy China.

ABSTRACT
BACKGROUND:Tissue engineering involves many disciplines such as biology, material science, medicine and engineering, so, the col aboration among different research departments is becoming an important factor to enhancing research outputs with the rapid development of related sciences and technologies. OBJECTIVE:To draw the visualizing map of col aboration network of animal-derived regenerative implantable medical devices based on tissue engineering technology and describe its evolving process and current situation. METHODS:2 518 Chinese literatures about the animal-derived regenerative implantable medical devices based on tissue engineering technology published before 31 December 2014 were searched in CNKI, WANFANG DATA and VIP. Subsequently, social network analysis was conducted on those literatures by utilizing UCINET software and SASI developed by Peking University. RESULTS AND CONCLUSION:The col aboration network of the animal-derived regenerative implantable medical devices has evolved from scattered to single-core dominated, and then to a core-edge one, characterized by increasing and extensive col aborations as wel as decreasing network density and centralization. The core units from 2010 to 2014 include Tsinghua University, General Hospital of Chinese PLA and Affiliated Nanfang Hospital of South Medical University. Also, plenty of edge institutes exist. In conclusion, edge institutes should expand their scope of cooperation, while core institutes should improve their cooperation sustainability. Furthermore, cooperation among enterprises, research institutes and clinical hospitals should be strengthened to promote the industrialization of tissue engineering technology.
