METHODS:The population of patients consisted of subjects in whom H pylori infection had been successfully treated in the past.Patients were divided into two groups:Ⅰ-examined group(111 persons with H pylori re-infection)andⅡ-control group(175 persons who had not been re-infected).The respondents were interviewed retrospectively on their dietary habits and socio-economic factors. RESULTS:A statistically significant lower frequency of fermented dairy products(P<0.0001),vegetables (P=0.02),and fruit(P=0.008)consumption was noted among patients with H pylori re-infection as compared to those who had not been re-infected. CONCLUSION:High dietary intake of probiotic bacteria,mainly Lactobacillus,and antioxidants,mainly vitamin C(contained in fruit and vegetables),might decrease the risk of H pylori re-infection.展开更多

A proposal of assessment of the vulnerability of the environment and community is presented here under a holistic perspective using fuzzy logic as a formal tool. An internal factor of the risk of a system under a given threat is assessed. Risk is considered as the union between the threat and the vulnerability of the environment and community. This approach shows that the reduction in either or both of them makes a reduction in the risk content as well. The main purpose of this proposal is not to obtain a single value as output; in fact the result is a map which can contribute to the different areas of the community in decision making.展开更多

Economic law is a general term of legal nomas to adjust social relations occurred in the course of state regulation of the economy, so that to protect state regulation, and promote social and economic coordination, stability and development. From the view of the generation of the law, economic law is generated after the emergence of the socialization of production and monopoly to protect the public interest. Economic law is bound to reflect social justice in the redistribution process of interests. Legislative intent of economic law to maintain a fair society is reflected through the redistribution process of the interests. Redistribution of the economic law is an important means to achieve social justice.展开更多

It mainly introduced and analyzed low carbon development which was addressed as crucial initiative for implementation of LCS in China. A comparative analysis was carried out on concepts and experiences of LCS between China and developed countries. The trends and characteristics of CO2 emissions in China have also been analyzed. Because of large amount of CO2 emissions generated in the production process and relatively small amount of CO2 emissions in the consumption process, China is facing a severe challenge of imbalance in economic growth and CO2 emissions. If the consumption and production pattern of developed countries are duplicated, China is very likely to experience a development pattern of boosting economic growth and improving living standards significantly but meanwhile risking and suffering by large amount of resources consumption and CO2 emissions. Thus, a comprehensive, systematic and scientific scheme for implementing a low carbon society is urgently needed in China. Through literature research, mainstream perspectives of scholars with respect to development of LCS are concluded. In the meantime, CO2 emissions reduction target, carbon taxation and different debated issues are also presented. The achievements, China has rflade, consist of concrete actions taken by local governments, some new policies and regulations for carbon reduction at national level, in particular energy-saving and renewable energy policies proposed in the l lth Five-Year Plan (2005-2010). Carbon trading markets and carbon capture and starage technology have also made progress in China. There are still many limitations and barriers remaining and in need to be solved in the next steps.展开更多

Many rural areas suffer a shortage of energy, and consequently, possibilities of social and economic development of the inhabitants become reduced. The activation of renewable energy sources in these areas presents inhabitants the advantages to generate their own energy. Dispersed rural communities create small electricity demands that are not considered by suppliers, because they are not profitable. Although thus far, feasibility analyses to install photovoltaic or thermal solar collectors are based on technical reasons, it seems more convenient that, in the future, projects for the installation of technology based on renewable energy should consider social indicators. As a preliminary step to field work is proposed in this paper using an equation that allows us to obtain a value of"social index". With this analysis and the current survey accompanied by the local people, knowledge will be obtained of the real needs of these rural communities. The results show that there is a variation that would allow a classification or ordering of localities. To validate the results obtained is proposed as the next step to perform field work in each of the localities.展开更多

Certain energy efficiency retrofitting obligations have now emerged as part of the EU's Energy Performance in Buildings Directive and the Energy Efficiency Directive. Challenges for retrofitting currently include gaps in technical skills both amongst building trades and professionals, a lack of awareness of building owners and users, concerns about compromising cultural heritage as well as a lack of viable business models, comparatively high cost and resulting long pay-back periods currently hamper the progress. Lessons can be drawn here form the EU-funded initiative CONCERTO, which helped 58 communities in 23 countries to reduce their dependence on conventional energy supply by implementing energy efficiency measures and integrating renewable energy sources not at single building scale but community scale. Almost all of these entailed retrofitting activities bad to find solutions to the issues mentioned. This paper presents a selection of conclusions regarding retrofitting to be drawn from the analysis undertaken under the project CONCERTO premium, which analysed outcomes across the 58 projects on behalf of the European Commission and focuses in particular on the political relevance of outcomes.展开更多

The case study will be Avenidas Novas district, in Lisbon, Portugal, as it is a paradigmatic example of a central area which coexists with dynamism and decadence. The development model for Avenidas Novas was inspired on French boulevards and was planned to be the modem face of a medium to high social class population, as it was until 1940s. Today, as a consequence of further developments which corrupted the first principles and concept, its urban fabric is becoming less coherent and adequate to the needs of the population who works and lives there. From an analysis to the various components of the urban fabric, the paper will identify the major problems that are happening on the site, related to accessibility, mobility and functional diversity. Once understanding the impacts of an unsustainable territory management and urban design, the goal is to develop the principles for a creative urban regeneration strategy for Avenidas Novas district. The study will be based on the theoretical issues of the compact city and walkable distances in order to develop quantifying parameters of urban quality and to promote human scale public spaces and territorial cohesion on an urban environment.展开更多

Methods: Sixty rats were randomly assigned to five groups (12 in each group): a normal control group (group A), a sham-operation group (group B), an operation group (group C), an Edaravone group (group D) and an EA group (group E). The cerebral IRI rat model was induced by middle cerebral artery occlusion (MCAO) using intraluminal monofilament. 2,3,5-triphenyl tetrazolium chloride (TTC) staining was adopted in the measurement of cerebral infarction volume. Real-time polymerase chain reaction (RT-PCR) was used to determine the mRNA expressions of CHOP and caspase-12. Results: Compared with group A and group B, the volume of cerebral infarction and mRNA expressions of CHOP and caspase-12 in group C, group D and group E were increased, with statistical significances (P〈0.05 or P〈O.01); compared with group C, the volume of cerebral infarction and mRNA expressions of CHOP and caspase-12 in group D and group E were decreased significantly (P〈0.05 or P〈0.01); there were no significant differences between group D and group E in comparing the above items (P〉0.05). Conclusion: EA at Neiguan (PC 6) and Baihui (GV 20) can effectively suppress the volume of cerebral infarction. Furthermore, the underlying mechanism of EA at Neiguan (PC 6) and Baihui (GV 20) is possibly related to the down-regulation of CHOP and caspase-12 mRNA expressions, so as to decrease cell apoptosis.展开更多
