ABSTRACT
Objective to investigate the outcome and EP treatment outcome of small‐cell lung cancer (SCLC) patients with different hyponatraemia .Methods This retrospective study analyzed the relationship between the serum sodium ,serum osmolality , urine sodium ,urine osmolality and survival time of 51 patients .Moreover ,we analyzed the survival time and chemotherapy outcome of SCLC patients in hypovolaemic and euvolaemic hyponatraemia .Results The data indicated that the serum sodium and osmolality correlated with the survival time positively ,and the pearson correlation coefficient are 0 .48 [95% CI:(0 .23 to 0 .67)]and 0 .61 [95% CI:(0 .40 to 0 .76)] ,respectively .urine sodium and osmolality correlated with survival time negatively ,and the pearson corre‐lation coefficient are -0 .6 [95% CI:(-0 .75 to -0 .38)] and‐0 .31 [95% CI:(-0 .54 to -0 .04)] ,respectively .Etoposide plus cisplatin treatment showed less effectiveness to the SCLC patients in euvolaemic hyponatraemia (29 .17% VS .66 .7% ,P<0 .05) , and the survival time of SCLC patients in euvolaemic hyponatraemia is shorter (33 .3% VS .92 .6% ,P<0 .05) .Conclusion Euvol‐aemic hyponatraemia could be a risk factor for poor outcome in SCLC .
ABSTRACT
Objective To build the dataset of Chinese visible human female. Methods After undergoing macroscopical, CT and MRI examinations to exclude organic lesions, a young female cadaver of medium height was selected as the subject. After morphological measurement and vascular perfusion, the cadaver was embedded with 5% gelatin and cryopreserved in a -30 ℃ icehouse for 1 week. A digital milling machine TK 6350 (milling accuracy of 0.001 mm) was used to shave off slices of the body layer by layer from head to foot in a laboratory at -25 ℃. The successive cross sections were photographed with a high definition digital camera, and the pictures were put into a computer to establish a dataset of human body. By utilizing the image dataset derived from the successive cross sections, 3D reconstruction and stereodisplay of human structure were finished with a SGI Workstation which was equipped with an independently self developed software package for 3D reconstruction. Results The selected specimen, a 22 year old female native of Chongqing, was 1 620 mm in height, 54 kg in weight and died of non organic disease. CT scans were made in every 1.0 mm for head and neck and every 2.0 mm for rest parts, and the thickness for MRI scans was 1.5 mm for head and 3.0 mm for rest parts. For serial cross sections, the thickness was 0.25 mm for head and 0.5 mm for rest parts. Thus, a total of 3640 slices were obtained, and the photo for every slice was saved as a 36 MB file in a resolution of 6 291 456 pixels (3 072?2 048). Finally, the complete data files reached to 131.04 GB. Conclusion ① This is the first formally reported case of Chinese visible human female, suggesting that China becomes the second country owning visible human female dataset of her population. We set up a website for the purpose of exchanging ideas and information on this subject. So, the results are issued simultaneously on the Internet (http://www.chinesevisiblehuman.com).② According to US Visible Human Project(VHP), the data of the 3 junctional parts of their female cadaver were absent because the body was cut into 4 segments. Taking the age of 59 year old into account, the visible human female's body was not exactly perfect. The sections of 0.33 mm in thickness were saved to pictures at a resolution of 2 490 368 pixels (2 048?1 216). While, the first Chinese visible human female reported here is a young female without organic disease or lesion. No sectional datum is lost for being acquired from successive sections of the whole body. The resolution of cross sectional image reaches to 6 291 456 pixels (3 072?2 048).
