Résumé
Aim To investigate and compare the phar-macokinetics of doxapram injection in healthy subjects of different Chinese nationalities including Han, Mon-golian, Korean, Hui and Uigur, and the influence of gender,in order to provide instruction and help for the usage of doxapram for both clinic and remedy of battle wound. Methods An HPLC-UV method was used to determine the plasma concentration of doxapram. Fifty healthy subjects ( five males and five females of each nationality) were recruited for the study. A single dose of 50 mg doxapram was administered intravenously to the healthy subjects, and blood samples were collected at various predetermined time points. The pharmacoki-netic parameters were calculated by DAS software and were compared by SPSS 13. 0 software, in order to as-sess the influence of nationality or gender on pharmaco-kinetics of doxapram. Results The results indicated that the pharmacokinetic profile of doxapram in vivo could be described as two-compartment model. The main pharmacokinetic parameters for Han, Mongolian, Korean, Hui and Uygur were as follows: Cl ( 0. 25 ± 0. 11 ) , ( 0. 33 ± 0. 11 ) , ( 0. 27 ± 0. 07 ) , ( 0. 26 ± 0. 06) and (0. 39 ± 0. 25) L·h-1 ·kg-1 , while Cmax (1. 55 ± 0. 52 ) , ( 1. 02 ± 0. 30 ) , ( 1. 31 ± 0. 47 ) , (1. 48 ± 0. 46 ) and ( 0. 99 ± 0. 35 ) mg · L-1 . The AUC0-12. 5 , AUC0-∞ and Cmax of Chinese Han were sig-nificantly higher than those of Uigur and Mongolian ( P0. 05 ) . There were statistically significant differences in Vc , Vd and CL between young males and females ( P < 0. 05 ) . Conclusion The large inter-individual variation in the main pharmacoki-netics suggests the dosage of doxapram should be ad-justed for different nationalities for both clinic and rem-edy of battle wound.
Résumé
Objective To study the biological macrofeatures and criterion thereof for fracture immobilization in Chinese Mongolian traditional osteopathy. Method The principles and methods of modern physiological psychology and biomechanics were used in this study to explore the biological macrofeatures and criterion thereof for fracture immobilization, based on the view of the harmony of human and nature (including a unity of body and function) in Chinese Mongolian traditional osteopathy. Results Chinese Mongolian traditional osteopathy implies the biological macrofeatures and criterion thereof for “dynamic immobilization” in fracture treatment, including the stability of structure and force catched, state of static and dynamic, forming and destroying of bone, physical and psychological stability. Therefore, it is a kind of non invasive and non shelter fixing method. Conclusions The biological macrofeature and criterion thereof for the fracture dynamic immobilization in fracture treatment, in Chinese Mongolian traditional osteopathy is not only the fundamental support for its inheritance up to now, but also could be a new attempt in modern fracture immobilization.
