Conclusions The selection of methods for breast reconstruction is simplified according to this preoperative evaluation system.

Objective To set up a method of three-dimensional breast volume measurement, to observe the effect of the artificial influencing factors on the final data, which are used for 3-D reconstruction of breast volume. Methods The CT data were used to reconstruct a digital prototype of the breast implant and the chest. The 3-D models were established firstly, and then the model was reasonablly cut to get single breast volume, breast implant volume, differences of the both sides of chest and breast volume. These methods were put up by the repeated test when the reference frame and the ranges were fixed. And the analysis of the artificial influencing factors was performed on 10 women whose breasts were unsym-metrical. The effects of the artificial influencing factors were analyzed by moving the coordinate axis, revolving the chest around the coordinate axis and changing the selected area. Results The repeatable test showed that the error was less than 4. 08 ml. The average volume differences between both sides of the breast before and after the given influencing factors were set, were 10. 339 ml and 7. 73 ml, as moved ± 4mm along the axis X; as revolving ±2° along the axis Z, that were 8. 654 ml and 7. 971 ml; as increasing or decreasing of the selected diameter of ± 4 mm, that were 6. 764 ml and 4. 267 ml, respectively. Conclusion Using the 3-D reconstruction technique for breast volume measurement is more simple, accurate and repeatable.

Objective To investigate the cognition and participation on organ donation in ICU medical staff and analyze the influencing factors, thus to provide reference for the development organ donation promotion measures. Methods 265 ICU medical staff were chosen by convenient sampling method from 10 three-level hospitals in Chongqing and were investigated with a self-designed questionnaire about the cognition, willingness and its influencing factors towards organ donation. Results ICU medical staff′s understanding of brain death, significance, basic conditions and concepts of organ donation were 67.2% (178/265), 61.1% (162/265), 60.0% (159/265), 55.8% (148/265) respectively, but understanding of Principles , registration methods, laws and regulations, and procedures of organ donation were 24.5%(65/265), 12.1%(32/265), 7.9%(21/265), 4.5%(12/265) respectively. 47.5%(126/265) ICU medical staff were willing to donate their own organs, 35.8%(95/265) were consented to relative′s organ donation and 4.5% (12/265) were organ donation applications. 89.1% (236/265) were affected by traditional ethical concepts, 70.2%(186/265) were for the publicity not enough, 51.7%(137/265) did not know about the procedures of organ donation, 37.0%(98/265) were for too much troubled procedures, and 43.8%(116/265) were for the ineffective work of relevant organizations. Conclusions Lacking in-depth understanding of organ donation and low willingness to donate organs in ICU medical staff in Chongqing. Mainly associated with the effect of traditional concept and lack of propaganda to the donation.

Objective To compare the efficacy and resistance between S?1 combined with radiotherapy and S?1 alone in the treatment of elderly patients with locally advanced gastric cancer. Methods Fifty?eight elderly patients with unresectable locally advanced ( stage Ⅲ) gastric cancer were randomly and equally divided into S?1 combined with concurrent radiotherapy group ( experimental group ) and S?1 alone group ( control group ) . The experimental group received 4 cycles of S?1 treatment with each cycle containing two?week oral administration of S?1 at a dose of 40 mg/m2 twice a day followed by one?week drug withdrawal. Gastric intensity?modulated radiotherapy was performed concurrently with a dose of 45 Gy ( 1. 8 Gy per fraction) . The control group received the same dose of S?1 alone. Short?term outcomes and adverse reactions were evaluated in the two groups. Comparison was made by chi?square test. Results All patients completed the planning treatment. The experimental group had significantly higher objective response, disease control, and symptom remission rates than the control group ( 52% vs. 24%, P=0. 03;76% vs. 45%, P=0. 016;86% vs. 48%, P=0. 005) . There were no significant differences in the incidence of nausea and vomiting, anorexia, leukopenia, diarrhea, or thrombocytopenia between the two groups ( all P>0. 05) . Conclusions S?1 treatment combined with concurrent radiotherapy improves the short?term outcomes and causes tolerable toxicities in the treatment of elderly patients with locally advanced gastric cancer.

The fetal spleen cells were transplanted following the injection of S180 carcinosarcoma into the muscle,abdominal cavity,peripheral veins and portal vein in mice.The size inhibitory rate of the transplanted tumor and natural killer activity were evaluated 30 and 60 days after the injection.It was found that the growth of transplanted tumor was dramatically inhibited and natural killer activity was increased 30 days after the transplantation.But 60 days after the transplantation only portal venous transplanted tumor showed a satisfactory function of inhibiting tumor growth and natural killer activity maintained at a high level.These results indicated that portal vein was the best approach for the spleen cell transplantation

Objective To investigate secretory IgA change in uremic patients ane its relationship with inflammation. Methods Sixty uremic noneialysis patients( uremic non eialysis group)ane 60 hemoeialysis patients( hemoeialysis group ),the other 40 healthy volunteers( control group ) were selectee as our subjects. Enzyme linkee immunosorbent assay( ELISA)methoe were appliee to eetect the fecal secretory IgA content. Immune nephelometry were usee to measure the level of high sensitivity C reactive protein(hs-CRP). Results The level of fecal secretory IgA expression in hemoeialysis group((2. 39 ± 0. 81)μmol/ L)ane the non eialysis group((2. 43 ± 0. 84)μmol/ L)were significantly lower than that of the control group((2. 89 ± 0. 87)μmol/ L),ane the eifference was significant(F = 5. 042,P < 0. 01),while there was no significant eifference between the eialysis group ane the non eialysis group(P > 0. 05). The negative correlation was seen between secretory IgA content ane hs-CRP in patients(r = - 0. 629,P < 0. 01). Conclusion The secretory IgA eecreasee in patients with or without uremic eialysis ane it is correlatee with inflammatory state.
