[Effects of local carbon ion irradiation on survival and peripheral blood leukocyte and platelet counts of tumor-bearing mice].

OBJECTIVE: To investigate the effects of local carbon ion irradiation on the length of survival and peripheral blood leukocyte and platelet counts of mice inoculated with pulmonary tumor cells. METHODS: Thirty tumor-bearing mice were randomly divided into control group (tumor-bearing but without carbon ion irradiation, n=10), 12 Gy group (n=10) and 24 Gy group (n=10). The right hind limbs of the mice, where the tumor cells were inoculated, were irradiated with carbon-ion beams at a single dose in 12 Gy and 24 Gy groups, and those of the control group received no irradiation. The peripheral blood leukocytes and platelets of the mice in all the 3 groups were counted immediately before and 7 and 14 days after irradiation, respectively, with the survival time of the mice recorded. RESULTS: There was no significant difference in the survival time of the mice between the 3 groups. The peripheral blood leukocyte counts in all groups increased after irradiation, no significant difference was noted between the two irradiation the groups and the control group. Irradiation at 24 Gy resulted in significant increase in peripheral blood platelet count on the 14th day (P=0.032, F=4.062), but no such increment was observed in the other 2 groups or on day 7 in the 24 Gy group. CONCLUSION: Local carbon ion irradiation may not produce significant effects on the length of survival and hemogram of the tumor-bearing mice.

[The origin and development of special methods of "expiration and inspiration" (Tuna) in pre-Qin and Han dynasties].

Tuna (special methods of expiration and inspiration) was generated in the working life and health activities of the early stage of the human race in ancient times. It developed in the period of the Qin, Han and three kingdoms, developing the theory of bionic expiration and inspiration as well as the breath of the upper pubic region (Dantian); the skill of the Qi conduction school emerged so that the skills of embryonic breath and the upper pubic region breath came into being. The skill of meditation of the Chan sect of the Western Regions was also introduced into the central plains at this time. The skill of counting breath had a profound impact on the skill of embryonic breath of the Taoism elixir school.

[Research on developmental characteristic of the theory of ZANG-fu differentiation of syndromes in the period of Jin-Tang Dynasties.].

In the period from Jin to Tang dynasties, the Theory of Zang-fu differentiation of syndromes had been set up and prosperous. During this period, the first summary of the theory appeared, and the eight principles of Zang-fu differentiation, pulse diagnosis combining with Zang-fu theory upgraded to a new higher level, the application of medicines and prescriptions perfected. This theory was completely diffused into clinical practice. Since Taoism specifically stressed the theory of Zang-fu differentiation of syndromes, this theory expanded its influence and promoted its development.

[Studies on developmental features of theories of syndrome differentiation of zang-fu viscera in Qin and Han Dynasties].

The formation of the theories of visceral manifestations as well as channels and collaterals in the books Huangdi Neijing (Inner Canon of Huangdi) and Nan Jing (Classic of Questioning) laid down the theoretical foundation for the theories of syndrome differentiation of zang--fu viscera. From the early occurrence of syndrome classification to that of the disease manifestations of zang and fu viscera, the theories of syndrome differentiation of zang--fu viscera were basically not put into practice until Shanghan Zabing Lun (Treatise on Cold Pathogenic and Miscellaneous Diseases) appeared. The theories of syndrome differentiation of zang--fu viscera in the Qin and Han Dynasties were not systematic and were scattered, indicating that it was a period of gestation for the theories.
