People-oriented is the fundamental value of Chinese medical ethics.It is the most important ideological foundation and the most prominent features of the humanities of traditional Chinese medical ethics for its content of philosophy,humanity and sociology.A series of medical ethics incident alerts us that if we violate the scientific concept of "people-oriented" and neglect the requirements of medical ethics and professional ethics training,the development of medicine will lose its orientation,and even depart from the fundamental tenet of people-oriented.

BACKGROUND: Human body is an irregular geometrical one, so it is very difficult to measure its volume.OBJECTIVE: To establish a multiple regressive equation by taking body height and body mass as the independent variables and body volume as the dependent variable, and select optimally the body volume calculative model of male college students.DESIGN: A single-sample univariate analysis.PARTICIPANTS: Twenty-four male students aged 18-22 years were selected from Zhejiang Gongshang University between January 2003 and October 2004.METHODS: The body height, body mass and body volume of the male students were measured. The indexes of body height and body mass were measured with the nationally-recognized fitness test instrument, and the indexes of body volume were measured with a self-made iron container with a diameter of 0.95 m and height of 1.20 m. There was a mark scale for height in the container, water was infused to a fixed height, then the student slowly immersed himself into the water completely and the height difference was recorded. Body volume (m3)=(0.95÷2)2×3.141 59×height difference. The measured data were statistically calculated. A regression equation in two unknowns was established by taking body height and body mass as the independent variables and body volume as the dependent variable with the systematic software for statistical treatment of physical education scientific research data, and the optimal selection of the regression equation was completed.MAIN OUTCOME MEASURES: The measured data of body height,body mass and body volume and the calculative results of the regression equations were observed.RESULTS: ① A regression equation in two unknowns for calculating body volume was established: (^)y=0.006 16 +0.000 022 ×body height +0.000 756×body mass. ② A regression equation in one unknown for bodyvolume and its optimal selection: The linear equation was (^)y=0.000 8×body mass+0.009 2, the logarithm equation was (^)y=0.050 8 Ln(body mass)-0.152 4, the power equation was (^)y=0.001 8×body mass 0.840 9, the exponent equation was (^)y=0.025 8×e0.012 6x, and the multiple correlation coefficient R2=0.992 1-0.997 3, all were close to 1, indicating that the body volume predicted by models was highly correlated with the actual one [r＞r0.001(24-2) , P ＜ 0.001]. The predicted values of the 4 models had no differ-ence from the actual one. ③ Linear equation had the best simplicity in measurement and calculation in the 5 regression equations. ④ The indexes of physical quality, which were highly correlated with body volume,were body shape, physical function and physical quality.CONCLUSION: The index of body volume is one of the important indexes, which cannot be neglected in the study of physical quality. Analyzing from the simplicity of measurement and calculation and the linear goodness-of-fit of equation, the regression equation in one unknown is the best.

Purpose To investigate the correlation of CT features with peripheral blood eosinophil count and proportion in eosinophilic gastroenteritis (EG).Materials and Methods Seventeen cases of clinically confirmed EG were retrospectively analyzed.The lesions were observed based on CT findings,and the count and proportion of peripheral blood eosinophil were calculated.Results Among 17 cases of EG patients,2 cases had one lesion,the peripheral blood eosinophil count and proportion of which were (0.28±0.22)× 109/L and (4.85 ± 2.19)％,respectively;5 cases had two lesions,the eosinophil count and proportion of which were (3.19± 1.82)× 109/L,(37.04± 11.36)％,respectively;6 cases had three lesions,the eosinophil count and proportion of which were (3.93 ±2.37)× 109/L and (45.22±22.99)％,respectively;3 cases had four lesions,the eosinophil count and proportion of which were (6.48±0.34)× 109/L and (75.83± 9.33)％,respectively;1 case had seven lesions,the eosinophil count and proportion of which were 8.87× 109/L and 75.60％,respectively.Conclusion There is a certain correlation of the peripheral blood eosinophil count and proportion with EG lesions.When the count and proportion of peripheral blood eosinophil increase significantly,the range of lesions may become more extensive,which suggests the scope of endoscopy or imaging examinations should be expanded in clinical work.

To investigate the temporal variation of cell-mediated immunity in injured tissue of maxillofacial firearm trauma. Cells expressing messenger RNA(mRNA) for IL-2 were demonstrated by dot blotting and in situ hybrization in injured tissue of maxillofacial trauma inflicted by bullet, in conjunction with immunohistochemistry for IL-2 in normal and postinjury conditions. It was found that, apart from a transient eleratim in level within 24h post injury, both IL-2 production and IL-2 mRNA expression were consistently suppressed in cells at the site of the wound compared with the normal. The changes in the tissues of indirect injury by the projectile were significant. These results indicate that the cell-mediated immunity was suppressed in maxillofacial firearm trauma and the principal cellular abnormalities that resulted in altered T cell activation and IL-2 production postinjury was downregulation of mRNA before IL-2 gene transcription. It also suggested that the indirect injury by projectile contribute mainly to the depression of cell-mediated immunity.

Objective To explore the relationship between postoperative cancer-related fatigue and nutritional risk in patients with colorectal cancer. Method Using convenience sampling method, 159 postoperative colorectal cancer patients were interviewed with cancer-related fatigue scale and PG-SGA 7 days after operation. Results The average score of CRF was (21.28 ± 6.06). The score by PG-SGA was (15.18 ± 5.55). About 94.34%patients were in need of nutritional intervention. The postoperative cancer-related fatigue was positively related to PG-SGA scores(all P<0.05). Conclusions The postoperative colorectal cancer patients are at a high risk of malnutrition, with nutrition risk positively related with somatic cancer-related fatigue. The clinical nursing staff should pay attention to the nutritional status of patients and correct their malnutrition so as to reduce the symptoms of cancer-related fatigue.
