The purpose of this study is to search into the relation between the chinese seclusion culture and the gentleman's gardens by means of the historical and aesthetic approach. The periodic limits of this study is from pre-Qin to Tand. For gentleman's gardens in Tang dynasty at once got out of the noble's gardens which had imitated the imperial gardens until Tang, and became the origin of the gardens of the literati appearing in post-Tang dynasty. The major findings are as follows : First, in pre-Qin period, the origin of the seclusion culture is classified as the metaphysical seclusion of Taoism and the physical seclusion of Confucianism. Although Pu, Yuan, and Uou which could be said the first step of the chinese gardens were inquired, the clear relation between the seclusion and them is not found. Second, during Qin-Han dynasty, the role of the gardens, as the settings of the seclusion, are comparatively minor, too. But uan Kuang-Han's garden considerably escaped from that of pre-Qin in the aspect of function, and it has the characteristics of recreation. Third, during Wei-Chin and Liu dynasty, two types of the seclusions emerged. One is the small seclusion, and the other the Great Seclusion. Though, as formerly, the contemporary gardens did not escaped from the imperial gardens, Shi Chong's garden can be the setting of the Court Seclusion. But the seven Righteous in Bamboos' and Tao Yuan-Ming's settings of the seclusion were real natural environments rather than gardens. Forth, in Tang dynasty, in spite of relatively low status, Bai Ju-Yi's theory of the middle Seclusion enabled gentlemen to make seclusion in sinecures unlike the court Seclusion. The theoretical background of the Middle Seclusion was Zen Buddhism and the State Examinations System and Bai Ju-Yi's private social position also had an important effect on it. In Tang dynasty, there being nobiliary gentleman's gardens, Bai Ju-Yi's garden, Lushan Caotangyuan, was the setting of the Middle Seclusion. It can be called a real gentleman's garden, for it is simple and small unlike the imperial gardens or the nobiliary gentleman's gardens.

Although the 'Buzhēng' theory of the Pre-Qin Period did not develop through fierce controversy, it has been universally and consistently argued in the writings of disciples including Taoism and Confucianism. The meaning and value of 'Buzhēng' theory is as follows: first, it is the 'modernity' of 'Buzhēng' theory. In general, philosophical ideals and cultural codes in ancient cultures do not have sustainability beyond the times. However, 'Buzhēng' theory communicates with people through the times. Second, the 'Buzhēng' theory focuses on the problem of the human being and calls for reflection and effort on the human being. The greatness of man is to reflect on his life in order to understand himself in the flow of history. Therefore, 'Buzhēng' theory is both a human principle and a human method. Third, 'Buzhēng' theory is based on humanity. We desire to be an indifferent being and to ask for higher altitude through self-sacrifice. Lastly, 'Buzhēng' theory is a very detailed account of human individual life.

Objective: Low dose radiation may stimulate the growth and development of animals, increase life span, enhance fertility, and downgrade the incidence of tumor occurrence.The aim of this study was to investigate the antitumor effect and hormesis in an erythrocyte system induced by low-dose radiation. Methods: Kunming strain male mice were subcutaneously implanted with S180 sarcoma cells in the right inguen as an experimental in situ animal model. Six hours before implantation, the mice were given 75mGy whole body X-ray radiation. Tumor growth was observed 5 days later, and the tumor volume was calculated every other day. Fifteen days later, all mice were killed to measure the tumor weight, and to observe necrotic areas and tumor-infiltration-lymphoreticular cells (TILs). At the same time, erythrocyte immune function and the level of 2,3-diphosphoglyceric acid (2,3-DPG) were determined. Immunohistochemical staining was used to detect the expression of EPO and VEGFR of tumor tissues. Results: The mice pre-exposed to low dose radiation had a lower tumor formation rate than those without low dose radiation (P < 0.05). The tumor growth slowed down significantly in mice pre-exposed to low dose radiation; the average tumor weight in mice pre-exposed to low dose radiation was lighter too (P < 0.05). The tumor necrosis areas were larger and TILs were more in the radiation group than those of the group without radiation. The erythrocyte immune function, the level of 2,3-DPG in the low dose radiation group were higher than those of the group without radiation (P < 0.05). After irradiation the expression of EPO of tumor tissues in LDR group decreased with time. LDR-24h, LDR-48h and LDR-72h groups were all statistically significantly different from sham-irradiation group. The expression of VEGFR also decreased, and LDR-24h group was the lowest (P < 0.05). Conclusion: Low dose radiation could markedly increase the anti-tumor ability of the organism and improve the erythrocyte immune function and the ability of carrying $O_2$. Low-dose total body irradiation, within a certain period of time, can decrease the expression of hypoxia factor EPO and VEGFR, which may improve the situation of tumor hypoxia and radiosensitivity of tumor itself.
