The fourth new farming model Fenlong is identified as megascience for the first time. Fenlong can be directly applied to farming of farmland, remoulding of mortar black soil and saline alkali land and development of degraded grassland. Deep loosening can create huge soil reservoirs, reduce fertilization, promote indi- rectly the improvement of river water fisheries and water sources and the upgrading of shaping and hydropower industry, thus making a new round of mobilization and pooling of natural resources. As a result, the nature is able to produce good food needed by human, the spatial dimension of the land is increased, the natural pre- cipitation storage is increased, the flood and drought disasters are reduced, the eco-environment is improved, and the economic benefits are increased. Fenlong is not restricted to global application by ecological region and crop variety and is not subject to the time-space constraints for a hundred thousand years. On the basis of utilizing the heaven and earth resources, it brings about a huge effect of mega- science. Compare with traditional farming, the depth under the mode of Fenlong is increased by 2-3 times, the contents of nutrient, water, oxygen and microorganism in the soil are increased by 10%-200%, the content of pale salt is increased by 20%-40%, the temperature is increased by 2-4 ~C, and the photosynthetic efficiency of crops is improved by 10%. Under the cultivation mode of Fenlong, the yield of crop applied with no fertilizers is increased by more than 10%, crop yield is still in- creased by more than 5% when the application amount of chemical fertilizer is re- duced by 10%-20%. Under the farming mode of Fenlong combined with no in- crease in fertilization, the crop yield, crop quality, farming efficiency, natural precipi- tation storage and air humidity are increased by 10%-50%, 5%, 15%, 100% and 5%, respectively, and the emissions of methane and other gases are reduced by more than 5%. Even in mortar black soil, saline alkali land and degraded grassland, the yield is still increased by 15%-50%. These improvement effects can last for many years, helping achieve the real harmonious coexistence between human and nature. 展开更多

This study aimed to alert people that the harmony between human beings and nature has already become an urgent problem. All people are responsible for maintaining the harmony, which is the also the inexorable trend of historical development. Reviewing the evolution history of human kind, the relationship between human beings and nature from harmony to imbalance, from imbalance to a new harmony was analyzed from the macro perspective, and it was pointed out that the present society is in the transitional phase from imbalance to a new harmony and also a phase that people are consciously coordinating their relationship with nature. It was found through the study that a harmonious society relies on the harmony between human beings and nature, and the latter is a necessary condition for a real harmonious society, however, people always forget such a principle. The imbalanced relationship between human beings and nature has seriously influenced many aspects of social harmony, and become instable factors in China and international society, even threatened the development and survival of human beings. Thus, all people should make joint efforts in creating win-win conditions for the development between human beings and nature, and ensuring offspring a healthy and green earth. 展开更多

Dry valleys are a striking geographic landscape in Hengduan Mountains Region and are characterized by low rainfall, desert type of vegetation and fragile environment. Past efforts and resources have been concentrated mainly on rehabilitation of degraded ecosystem and fragile environment, particularly reforestation, while socio-economic development has been largely overlooked. Despite successes in pocket areas, the overall trend of unsustainability and environmental deterioration are continuing. It is important to understand that uplift of the Tibetan Plateau is the root cause of development of dry valleys, and development and formation of dry valleys is a natural process. Human intervention has played a secondary role in development of dry valleys and degradation of dry valleys though human intervention in many cases has speeded up environmental degradation of the dry valleys. It is important to understand that dry valleys are climatic enclaves and an integrated approach that combines rehabilitation of degraded ecosystems and socio-economic development should be adopted if the overall goal of sustainable development of dry valleys is to be achieved. Promotion of niche-based cash crops, rural energy including hydropower, solar energy, biogas and fuelwood plantation is recommended as the priority activities. 展开更多

The bacterial pathogen Helicobacter pylori (H. pylori) colonizes in over half of the world&#x02019;s population. H. pylori that establishes life-long infection in the stomach is definitely associated with gastro-duodenal diseases and a wide variety of non-gastrointestinal tract conditions such as immune thrombocytopenia. Triple therapy which consists of a proton pump inhibitor and combinations of two antibiotics (amoxicillin, clarithromycin or amoxicillin, metronidazol) is commonly used for H. pylori eradication. Recently, the occurrence of drug-resistant H. pylori and the adverse effect of antibiotics have severely weakened eradication therapy. Generally antibiotics induce the disturbance of human gastrointestinal microflora. Furthermore, there are inappropriate cases of triple therapy such as allergy to antibiotics, severe complications (liver and/or kidney dysfunction), the aged and people who reject the triple therapy. These prompt us to seek alterative agents instead of antibiotics and to develop more effective and safe therapy with these agents. The combination of these agents actually may result in lower a dose of antibiotics. There are many reports world-wide that non-antibiotic substances from natural products potentially have an anti-H. pylori agent. We briefly review the constituents derived from nature that fight against H. pylori in the literature with our studies. 展开更多

PURPOSE: To observe the effects of electroacupuncture therapy on T cells and activity of NK cell in the patient of Chemotherapy. METHOD: Electro-acupuncture therapy was simultaneously applied during chemotherapy, T cells and activity of NK cell of patients were determined before electroacupuncture treatment (before chemotherapy) and after 4-course electro-acupuncture treatments. RESULTS: Before chemotherapy, CD3 was low within the normal range, CD4 was much lower than the normal range, and CD8, CD4/CD8 and activity of NK cell were within the normal range. After one month of chemotherapy combined with electro-acupuncture, no decline of all the indices was found (P > 0.05). CONCLUSION: Electro-acupuncture can really increase the immune function of patients of chemotherapy. 展开更多

We examined the possibility that the anti-estrogens, tamoxifen (TX) and toremifen (TO) interacted?with the immune system. Indeed, both TX and TO stimulated cells mediated cytotoxicity reactions by various killer cells: killer T (TK), natural killer (NK), lymphokine activated killer (LAK) cells. Both TX and TO inhibited the growth of tumors that express estrogen receptors. Thus these antiestrogens inhibited tumor growth and stimulated killer cells for cytotoxicty on such tumors. Therefore these agents were presumed to stimulate tumor immunity. We tested the P815 mouse mastcytoma with TK, LK, and TX or TO. A therapeutic effect was observed in both experiments. The SL2-5 murine lymphoma was tested with NK and TX cells or TO cells and successful immunotherapy was observed.?We digested human breast carcinomas and lung tumors with collagenase. The killer cells were separated from tumor cells on Ficoll gradients. TX and TO enhanced the cytotoxic effect of autologous killer cells on the corresponding tumor cells. This experiment indicates that the results obtained in animals are also valid for human malignant disease. 展开更多

Faced with the serious environmental crisis,the Seventeenth Congress of the CPC put forward the scientific concept of "ecological civilization",and the Eighteenth Congress of the CPC attached great importance to the construction of ecological civilization,the strategic position of which was equaled to that of the economic construction,political development,cultural development,social construction. In order to deal with the more and more serious environmental problems,enhance the harmony and unity between human beings and nature and create ideal environmental conditions for various courses and tasks,the entire allocation of the Socialism with Chinese characteristics has been changed from "four in one"to "five in one",in which the ecological civilization becomes a new component. Consequently,it is worthwhile to intensively study and grasp the Marxist ecological view and form the self-awareness of environmental protection to carry forward the ecological civilization construction of China. 展开更多

As a masterpiece of Hawthorne's works, The Scarlet Letter sets up on New England in the seventieth century and successfully depicts the cruelty of Puritan society and the kill to human nature. However, it seems that this is not the only purpose for the author to criticize the Puritanism. Hawthorne also endeavors to pursuit an ideal harmony through the image of the forest,which is omitted by most of the scholars who research Hawthorne's works, especially for The Scarlet Letter. In this thesis, it aims to illustrate the ideal harmony from two perspectives: first, the image of the forest stands for the harmony of the primitive life; second, the image of the forest represents the harmony of the development both in body and mind. 展开更多
