Abstract: Abstract： The present study, taking sexual offenders as researchobject, using the Chinese traditional medical diagnosticmethod. consulting the standards of classification for theconstitution types of Chinese traditional medicine draftedby Zho Guoxiong, Jinan University. adopting the objective cxaminating method of artcriogram. is focused on theunderstanding of the characteristics of sexual offenders' constition (Physical status ) at Chinese traditional medical angle. From the point of Chinese medical constitution Theo-ry, 101 cases of sexual offenders were studied. Amongthose there were podominence or yang (usually accom-panied with manifestations of heat, excitement. showinghyperfunction of the organism) in 17 cases, grand harmony of yin and yang (by which good health is guaranteed ) in 80 cases. and predominence of yin (usually accompanied with manifestation of cold, showinghypofunction of organism) in 4 cases, Those were compared with 41 cases of non-sexual offenders. The resultsshow, 9 cases with predominence of yang. 27 cases withgraand harmoney of yin and 5 cases with predominence ofyin. The results of the study show that the first point ingroup of sexual offenders on the arteria ulnaris arteiogramthe relative ratio of the upper 1 / 3 width of the main wavein the pulse cycle is obviously bigger than that of non-sexual offenders'. It indicates that the sexual offenders maintains a longer relative time in the state of vesselhypertonicity. This manifests that the excitement level ofsexual offenders' sympathetic nervous system may be higher than that or non-sexual offenders. The second point isthat the amplitute of notch at the decending branch of thepulse curve of left radial artery and the relative ratio of themain wave amplitute are obviously smaller than that ofnon-sexual offenders. This characteristic indicates that thesexual offenders' left radial artery are slightly smooth andquick. It is Possible that this very characteristic has somerelationship with the hyperfunction of sexual offenders'"Kidney and vital gate"The sexual of Tenders' pulse power of bilateral radialarteries incrasc progrssively (Predominence of yin→grand harmony→predominence ofyang ). Although the fact has no sense in statistics, It indicates the regular pattern or pulse power in different constitution classification.
