Syndrome scales were used to evaluate the efficacy in gastrointestinal syndrome. Fecal flora was also measured before and after the treatment. Six bacteria were cultured and the colony forming units were counted in stool. SPSS was used for data analysis. Results: Seventy-four patients finished the follow-up. No side-effect was found. For treatment of irritable bowel syndrome, the effective rate of live combined Bifidobacterium, Lactobacillus and Enterococcus capsules was 56.8% in the second week, 74.3% in the fourth week and 73.0% in the sixth week. Single symptom was improved, especially in abdominal pain and stool character. The probiotica containing live combined Bifidobacterium, Lactobacillus and Enterococcus could increase bifidobacterium count (P〈0.01) and lactobacillus count (P〈0.05); decrease bacteroides count (P〈0.05) and enterococci count (P〈0.01); No obvious changes were observed in clostridium diffcile colonitis and enterobacteriaceae (P〉0.05). Conclusion: The result of the study indicated that the administration of live combined Bifidobacterium, Lactobacillus and Enterococcus improved the symptom of irritable bowel syndrome and that there was a gradual increase of this effect. Thereafter conditions remained stable for 2 weeks. That improvement may be associated with alterations in gastrointestinal flora.展开更多

Contrarily to European writers, who searched its philosophical origins in irrational philosophical traditions, in the US, they relied upon the perception that Hegel's Philosophy of State was the most relevant ideological basis of National Socialism. Hegel's idea for the need of a strong state, seemed to clearly support the hypothesis. Herbert Marcuse, exiled in the United States, bad to confront himself with this conviction that academic colleague shared. This theoretical hypothesis was in tune to the Zeitgeist and the political context, in which anticommunism was growing stronger by the day and where the cold war was developing. Associating Hegel and National Socialism implied, for most of the hypothesis defenders yet another vantage point: it could discredit also Marx, for the tights links between his philosophical thinking and Hegel's one. For Marcuse this hypothesis was even more problematic knowing that in Germany, national socialist philosophers had rejected Hegel from the very first day their party came to power. In this article we try to analyze Marcuse's respective philosophical argument. The point of departure of this reconstruction is the philosophical interpretation of Hegel's theory of the State. Further than the historical context, the debate on Hegel and his theory of the State, is very relevant for today's debates, dominated by neoliberal ideologies, which often are starting from similar theoretical errors than the mentioned. In both cases exists a lack of understanding of the classic bourgeois content within the concept of the State, based on the French Revolution.展开更多

Judith Jarvis Thomson has contrived the most celebrated set among related ones, to wit the "violinist analogy," the "Good Samaritan" narrative, and the "Henry Fonda" allegory, by virtue of which, she intends, on the one hand, to argue that women's right to autonomy outweighs the alleged fetus's right to life, and on the other, to prove that no positive moral duties can be derived towards other persons alone from the fact that a moral agent is ascribed certain rights. What this short paper endeavors to prove is that Thomson's argumentation by analogy is a weak one, since neither the number nor the relevance of similarities invoked is adequate or satisfactory, while crucial parameters concerning the morality of abortion are being totally overlooked.展开更多

Still in a close affinity with Martin Heidegger, his teacher, Jonas argued that modem technology bore some annoying characters. In line of this anxiety, Jonas suggested the importance of protecting life as an integral part of the ethical project he intended to build. Departing from his basic notion that human life is never separated from other organic life, Jonas has opened a wider space for ethical responsibilities towards life of the whole cosmos. In what sense is his notion of the responsibility towards the whole life should be understood is one of the aim of this paper. Baring in mind that Jonas developed his concept on life and human responsibility towards it as an argumentation against the development of technology, the social context in which modem technology finds its root is worthed to be discussed. It is concluded that separating ethics from ontology as many theorists and philosophers did so far has strengthened the old notion of human autonomy with its defects, and by that, the destruction of life seemed to be accepted as a consequence of it.展开更多

This paper departs from such traditional subjects as the insight into the reason of Tess's tragic end by analyzing the character of the protagonists--Tess, Angel and Alec; or by dissecting the social environment. In this study, it represents the research by way of quoting several poems, expressing the meaning of the poems according to the development of the story to analyze the relationship between the poems and Tess's tragedy. It is concluded that poems cited by Hardy are the same as prophets' prophecies that indicate Tess's love tragedy: charming poems not only describe the short happy times of Tess, but also make a big contrast with her later unfortunate life; while the glooming poems appearing when Tess fell into plight, have their aims to increase the tragic atmosphere.展开更多

These traumas are entangled with disappointment, anger, fear, grief, desolation, and other emotions. In most cases, the literatus would turn to nature for relaxation and freedom, composing a lot of literatures in an attempt to reflect on the meaning of life. In this paper, I will analyze the written works of Qu Yuan, the Seven Sages in the Bamboo Grove (~tJ~$qS~), Liu Zongyuan, and Su Shi after they suffered political frustration to: (1) describe how their emotions changed; (2) illustrate how they built relationships between nature and self to relieve their frustrations; (3) clarify during these reflecting processes how they actually experienced the transformation and pursued the meaning of life; and (4) illuminate the significance of these pursuits, not only in spurring the boom of literal naturalism, but also in passing on the message for the current era with the joint crises of humans and the environment, to heal the earth and free themselves.展开更多

Also from the ancient age, we, humans, knew to mix colors with oil to draw. Materials at the time, however, were very gross with many shortcomings and limitations. Over the time, many generations of painters have taken great pains to search for materials and craped for paint. Nevertheless, only until the age of Van Eyck brothers (around 1390-1441) they gained great success in accomplishing and developing oil-painting techniques. Oil-painting colors until this age got purer, brighter, shinier, waterproof, sustainable, and endurable with time. Since then, oil-paint has been widely used in almost countries worldwide. It can be said that the accomplishment of oil-paint is a great technical revolution that changes and enhances the picture painting art. The painting ofoil in English means oil painting. It is the kind of the most popular and favorite pictures. It is called as the name of painting material. That is the oil paint that can be drawn on wooden, metal, and canvas surfaces, etc., Oil kinds with different materials will bring about kinds of oil paints with differentiated attributes. Oil paintings by Indian painters firstly appeared in those on Buddhism and they came to China from the 5th to 10th centuries but only until the 15th century, oil paintings got popular and developed. Oil paint finally became the key tool for painters to transfer into artistic works.展开更多

It is a profound transformation of techno-economic paradigms, imbedded in the technology, management, and institutional systems. As this revolution deepens, it is likely that manufacturing and the manufacturing sector would acquire new definitions. In addition, the resource foundation and factor structure, which are central to the competitiveness of a nation and an enterprise, would perhaps be reconfigured, hence rewriting the landscape of global industrial competition. Under this scenario, the "smiling curve '" which used to portray the economic features of the value chain, may change into a "silence curve" or even "sadness curve ". The catching- up pathway of latecomer countries, as predicted by the traditional 'flying geese model", is likely to be blocked, solidifying the division of"core and periphery countries" which is unfavorable to developing countries. Industrial competition between countries would move from competition between enterprises and supply chains to competition in industrial ecosystems, matdng system adaptability and dynamics the key to long-term industrial competitiveness. As an effort to embrace the "Third Industrial Revolution" and meet the challenges brought by "multi-facets competition" with developed industrial nations in various links of value chain, in the future China should make appropriate adjustments in its strategies for economic transition and upgrading, global competition, technological innovation, industrial development and information technology.展开更多

Such principles and norms are a typical expression of Chinese people's wisdom in the analysis of their surroundings. However, traditional Chinese culture also contains some poisonous thinking that has been carefully nurtured by feudal rulers to maintain their power. In the practice of the great social changes of pre-1949 China, after repeated experience, people gained a relatively clear and comprehensive understanding of traditional Chinese culture: it should neither be totally affirmed nor totally rejected. Rather, we should analyze it concretely, endeavoring to separate the dross from the essence. In late Qing and Republican China, traditional culture was continuously handed on and renewed, and this process will be carried on and on.展开更多
