OBJECTIVETo study on the relation between the regional anatomy and safety of acupuncture at Tiantu (CV 22) and Qishe (ST 11).

METHODSIn forty-six adult corpses, 92 sides were dissected to observe the partial anatomy structure of acupuncture path of Tiantu (CV 22) and Qishe (ST 11) and structure characteristics by the steel needle marked method and lay-by-lay dissection method.

RESULTSThe bilateral the pleura returning lines behind the manubrium sterni interacted at the sternal angle plane accounted for 50.0% of the total specimens and at the first ribs plane accounted for 6.5% of the specimens; for needling the point Tiantu (CV 22), left brachiocephalic vein was at the same level or close to the manubrium sterni upper fringe in 43.5% of the specimens, the left brachiocephalic vein and the middle of manubrium sterni were at the same level in 56.5% of the specimens; for needling the point Qishe (ST 11), in 68 sides of the specimens, internal jugular vein were pierced, accounting for 73.9%, and in 24 sides of the specimens the left common carotid artery were pierced, accounting for 26.1%; in 50 sides of specimens the vagus nerve were touched by the steel needle, accounting for 54.3.

CONCLUSIONIn acupuncture of Tiantu (CV 22) and Qishe (ST 11), the needle not only easily injure the upper pleural cavity, but also damage the big blood vessel and the vagus nerve in the mediastinum and the cervical root.

OBJECTIVE: To establish the linear regression equation between body height and combined length of manubrium and mesostenum of sternum measured by CT volume rendering technique (CT-VRT) in southwest Han population. METHODS: One hundred and sixty subjects, including 80 males and 80 females were selected from southwest Han population for routine CT-VRT (reconstruction thickness 1 mm) examination. The lengths of both manubrium and mesosternum were recorded, and the combined length of manubrium and mesosternum was equal to the algebraic sum of them. The sex-specific linear regression equations between the combined length of manubrium and mesosternum and the real body height of each subject were deduced. RESULTS: The sex-specific simple linear regression equations between the combined length of manubrium and mesostenum (x3) and body height (y) were established (male: y = 135.000+2.118 x3 and female: y = 120.790+2.808 x3). Both equations showed statistical significance (P < 0.05) with a 100% predictive accuracy. CONCLUSION CT-VRT is an effective method for measurement of the index of sternum. The combined length of manubrium and mesosternum from CT-VRT can be used for body height estimation in southwest Han population.
