In this scheme, the good thermal conductivity and insulation ceramic materials were selected as the outer jacket material sensing probe, and the program had a good solution to the problem of high and low voltage isolation; The combination of the optical fiber composite insulators for wireless sensing, not only solves the problem of high voltage insulation, but also avoids the ＂creeping＂ phenomenon due to dust. The package of the structure and reasonable installation solves the cross sensitivity of strain. The application showed that the precision of temperature measurement of the system could reach ± 0.5 ℃ and could work in a variety of harsh environments. It could improve the reliability of the operation of the electrical equipment significantly and has considerable practical value for the whole power system.展开更多

文摘Objective:Socioeconomic status(SES)is associated with childhood obesity,but the underlying factors remain unknown.This study aimed to identify mediators that may explain SES disparities in childhood obesity in China.Methods:Nationally representative longitudinal data from the China Education Panel Survey of 11 o019 children(13.03±0.79)collected from 2013-2014 to 2016-2017 academic years.Overweight/obesity was defined using Chinese national body mass index cut-points.Principal component analysis was used to convert the four SES indicators(maternal and paternal education,and occupation)into one comprehensive variable.Mediation analysis for SES disparities in childhood obesity was conducted using structure equation models.Results:The prevalence of overweight/obesity was 12.8%,and was higher in boys than in girls(17.8%vs.7.6%,P<0.001)at baseline.Among boys,relative risk(RR)of obesity was 1.23(95%CI:1.09 to 1.40,P<O.001)for per unit change in SES.There was no significant association between obesity and SES among girls.Mediation analyses showed that among boys,birth weight,being the only child in the family and children's selfperceived weight status mediated 70.0%of the effects of SES on obesity.No mediation effect was detected in girls.Conclusions:Chinese boys are more likely to be overweight or obese than girls.SES may impact childhood obesity through birth weight,being the only child in the family and children's self-perceived body weight status in boys,but not in girls.More attention should be made to address childhood obesity in high SES families among boys.Interventions targeting at these mediators are needed.

文摘A double burden of overweight/obesity and malnutrition during childhood is a major concern in China.Dietary intakes in this critical period affect children’s physical and cognitive development,and also have health consequences in later life.Therefore,establishing healthy eating habits that will endure is crucial for children.Nutrition education is an effective way in improving nutrition knowledge and attitudes,and healthy eating behaviors.Diverse forms of nutrition improvement programs that targeting children,family,teachers,and school settings have been conducted in many developed countries.However,due to the differences of genetic background,household environment as well as dietary patterns between Chinese children and children from other countries,the existing nutrition education programs for children abroad might not be appropriate for children in China.Thus,nutrition education programs that consider Chinese nutrition-related policies and food supply as well as the local educational resources are required for Chinese children.This review summarized nutrition-related policies and legislations in China and developed countries.A series of evidence-based nutrition education programs that combined educational strategies and environmental supports conducted in the Southwest China Childhood Nutrition and Growth Study were presented.These programs can serve as example models for adopting nutrition interventions to improve nutrition and health status of children in different regions of China.
文摘With the rapid development of new technologies and global trade and increasing collaboration am ong countries worldwide,public health has become a global issue.Global health,as a new discipline,has been drawing more attention from both academ ia and governments.The Belt and Road Initiative(BRI),proposed by China in 2013,aimed to prom ote trade and resource exchange,including education,research,and health issues,with over 60 countries in Asia,Africa,and Europe.The BRI provides good opportunities for involved countries to address health problems jointly as well.In response to the BRI and to promote international collaboration on global health issues,"The 2017 Belt and Road Initiative Global Health International Congress&2017 Chinese Preventive M edicine Association-Chinese Society on Global Health Annual Meeting"was held on Septem ber 24-27,2017 in Xi’an,China.Thus far,this is the largest high-quality international conference held in China that focused on the BRI global health issues.This article summarized the background,key sessions and topics covered during the congress,and important events,and highlights different perspectives of the BRI and global health by invited experts from China and abroad.The conference included 14 sessions(three keynote speech forums and ten scientific sessions and a research poster session)and about 100 speakers,around 40 of which were leading experts outside of China.All the major sessions were held in English.More than 40 leaders and experts of health sectors from 13 countries presented their work in the congress.Approximately 400 delegates from 29 countries attended the congress.Delegates had extensive discussions about global health related issues,future cooperation and development in global health.The congress fostered international exchange and collaboration.

文摘1.Introduction Obesity and non-communicable diseases(NCDs)are closely linked.NCDs,including heart disease,stroke,cancer,diabetes and chronic lung disease,are major disease burden worldwide,which collectively con-tributed to 71%of mortality globally.1 Almost three quarters of all NCD deaths,and 82%of the 16 million people who died prematurely(un-der 70 years old),occur in low-and middle-income countries.1 Obesity is associated with increased risks of many NCDs and premature death.Obesity is a major risk factors for some NCDs such as cardiovascular diseases,some cancers and type 2 diabetes.
文摘With an increasing proportion of sedentary lifestyle related chronic diseases,an efficient way to help fight the growing world epidemic of non-communicable diseases(NCDs)and promote public health in a fast-changing world is urgently needed.Exercise and medicine science have played an important role in prevention and control of NCDs.However,the current status and future development directions regarding the integration of exercise science and medicine(IESM)in China have not been well discussed.During 2017 Belt and Road Initiative Global Health International Congress&2017 Chinese Preventive Medicine Association-Chinese Society on Global Health Annual Meeting,Xi’an Jiaotong University Global Health Institute,and the Integration of Sport and Medicine Innovation Research Center,China Institute of Sport Science organized the IESM Forum on September 27.Six leaders and experts from China and abroad presented excellent research reports in the IESM Forum from several aspects.Experts reached a consensus at the end of their discussions that,in the near future,the IESM will be a key part of a sustainable health care system and as such should contribute to prosperity in China and around the world.However,compared with European,American and Japanese universities,the development of the IESM in China is in its early stages with huge development potential.

文摘As a superior alternative to sutures,tissue adhesives have been developed significantly in recent years.However,existing tissue adhesives struggle to form fast and stable adhesion between tissue interfaces,bond weakly in wet environments and lack bioactivity.In this study,a degradable and bioactive citrate-based polyurethane adhesive is constructed to achieve rapid and strong tissue adhesion.The hydrophobic layer was created with polycaprolactone to overcome the bonding failure between tissue and adhesion layer in wet environments,which can effectively improve the wet bonding strength.This citrate-based polyurethane adhesive provides rapid,non-invasive,liquid-tight and seamless closure of skin incisions,overcoming the limitations of sutures and commercial tissue adhesives.In addition,it exhibits biocompatibility,biodegradability and hemostatic properties.The degradation product citrate could promote the process of angiogenesis and accelerate wound healing.This study provides a novel approach to the development of a fast-adhering wet tissue adhesive and provides a valuable contribution to the development of polyurethane-based tissue adhesives.
文摘The outbreak of coronavirus disease 2019(COVID-19)has caused more than 80813 confirmed cases in all provinces of China,and 21110 cases reported in 93 countries of six continents as of 7 March 2020 since middle December 2019.Due to biological nature of the novel coronavirus,named severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)with faster spreading and unknown transmission pattern,it makes us in a difficulty position to contain the disease transmission globally.To date,we have found it is one of the greatest challenges to human beings in fighting against COVID-19 in the history,because SARS-CoV-2 is different from SARS-CoV and MERS-CoV in terms of biological features and transmissibility,and also found the containment strategies including the non-pharmaceutical public health measures implemented in China are effective and successful.In order to prevent a potential pandemic-level outbreak of COVID-19,we,as a community of shared future for mankind,recommend for all international leaders to support preparedness in low and middle income countries especially,take strong global interventions by using old approaches or new tools,mobilize global resources to equip hospital facilities and supplies to protect noisome infections and to provide personal protective tools such as facemask to general population,and quickly initiate research projects on drug and vaccine development.We also recommend for the international community to develop better coordination,cooperation,and strong solidarity in the joint efforts of fighting against COVID-19 spreading recommended by the joint mission report of the WHO-China experts,against violating the International Health Regulation(WHO,2005),and against stigmatization,in order to eventually win the battle against our common enemy—COVID-19.
文摘In view of the high voltage, the strong magnetic field environment of the high-voltage switchgear, the system based on the optical wireless sensing technology, realizes the isolated contact temperature monitoring of the high-voltage switchgear. In this scheme, the good thermal conductivity and insulation ceramic materials were selected as the outer jacket material sensing probe, and the program had a good solution to the problem of high and low voltage isolation; The combination of the optical fiber composite insulators for wireless sensing, not only solves the problem of high voltage insulation, but also avoids the ＂creeping＂ phenomenon due to dust. The package of the structure and reasonable installation solves the cross sensitivity of strain. The application showed that the precision of temperature measurement of the system could reach ± 0.5 ℃ and could work in a variety of harsh environments. It could improve the reliability of the operation of the electrical equipment significantly and has considerable practical value for the whole power system.
