[The author of Yi ding jie (Stepping to the Peak of Medicine) and its characteristics].

Yi ding jie (Stepping to the Peak of Medicine) was written by Huang Yuanying, a Hakka physician of Changting, Fujian at the turn of the Qing Dynasty and Republican period. Being a successful candidate of the imperial exam at the provincial level in the 20th year of Guangxu reign (1894) of the Qing Dynasty, he still practise as a physician. He had been a teacher of the Jiangxi Provincial Medical School and a supervisor of the Tingjun Middle School. He was conversant with the use of classical prescriptions, paid high attention to pulse taking. His work Yi ding jie is now collected in the Museum of Hakka Family Tree in Shanghang County, which was written in the form of traditional Chinese chapters of novel, bearing many case records, elaborating medical theory, reflecting from an aspect the medical level of Hakka medicine of that time, enlightening the inheritance of traditional Chinese medicine and its spreading for modern people.

[Analysis of the academic features of an Archiater LI Jun].

Li Jun, an archiater of Fujian with unique academic thoughts, was an excellent physician and scholar in the late Qing and early Republican period of China. In his clinicsal practice, Li Jun paid attention to the qi and blood, following the principles of boosting qi, moving blood and tonifying blood and put emphasis on the fullness and smoothness of the blood vessels. He also paid attention to cold damage and warm disease and was expert at applying classical prescription for epidemic syndromes, writing 'Shanghanlunwenda' ('Questions and answers to treatise on cold damage') in collaboration with Guo Yong-gan. He modestly studied from western medicine and made comparative study between the theories of western medicine and TCM, advocating integration of China and West and compiling the book of 'Investigation on Japanese medicine', books collection in Ashikaga. At the same time, he wrote 'Neijingnanjingjingshi' ('Explanation on internal classic and classic of difficulties') and 'Gulun' ('Treatise on bones'), consulting Kewei-liang's translation book: 'Quantichanwei' ('Interpretation of the whole body').

[Study of scintillating luminescence spectra of lead tungstate scintillation crystal doped with ions].

The light yield of the as-grown PbWO4, annealed PbWO4 and BaF2:PbWO4 crystals were raised by utilizing our improved crystal growth instrument and technique. Their scintillating properties including transmittance, decay time and light yield were studied. Results reveal that the scintillating performances of the crystals were improved evidently by using the crystal annealing technique and the ions doping technique, especially the negative ions doping technique. The influence results of the two techniques are different. The ions doping technique raises their transmittance intensity in the whole measuring wavelength range. But the influence of annealing PbWO4 crystal on their transmittance is complicated. It improves its transmittance intensity at the wavelength above 360 nm, but weakens the transmittance intensity of the annealed PbWO4 crystal in the wavelength range from 320 to 360 nm. These phenomena should be related to the crystal defects which have absorption peaks in this wavelength range, especially for V(Pb)3+ defect which has characterized absorption peaks in this wavelength range. Also, the absorption of the defects influences the character of the decay time of these crystals. The big defect concentration relates to the short decay time. It should be mentioned that the ions doping technique reduces the defect content in the crystal, which is beneficial to the high transmittance intensity but induces slightly longer decay time than that of as-grown crystal and well annealed PbWO4 crystal. Also, the ions doping technique of the F- ion doped crystal leads to high light yield. The annealing technique and ions doping technique improve the light yield of crystals. The light yield of BaF2:PbWO4 reaches 65 p.e./MeV, which is near to the requirement of PET. The good result is related to the degeneration of the [WO4]2- tetrahedron induced by the F- occupying the O2- site in the crystal cell.

[HUANG Yu-jie, the famous traditional Chinese medical physician of Taiwan in the late Qing dynasty and early republican period of China].

HUANG Yu-jie, the famous TCM physician of Taiwan in the late Qing dynasty and early Republican period of China, was a physician with noble medical morality and perfect medical skill. He made distinguished contributions especially to the prevention and treatment of epidemic disease. During the time he undertook the medical work, he also actively took part in the social activities and made changes in customs and traditions to promote the development of society. His medical morality and skill not only were the model for the medical field at that time but also had an extensive and profound impact on the common people.
