Objective To discuss the influence of bath frequency on neonatal skin condition and body temperature. Methods 108 newborns from obstetrics of People′s Hospital of Peking University during November 2015 to December 2015 were selected, and were randomly distributed t into two groups by lottery. The control group took bath every day, whereas the experimental group did every three days. The newborns were followed up for 4 weeks on their skin condition and body temperature. Then the data were systemized and performed statistical analysis. Results During the first 4 weeks after babies were born, the control group and experimental group showed no significant difference on their skin condition (P>0.05). When compared at the time of first 3 days, 1 week and 2 weeks after the babies were born, body temperature of the experimental group were (36.693±0.182), (36.738±0.174), (36.772±0.185)℃, while the control group were (36.591 ± 0.160), (36.671 ± 0.158), (36.684 ± 0.155)℃,which tended to be significantly lower than the experimental group (t values were -2.697,-2.087,-2.669, P <0.01 or 0.05), but still within the normal range. However, this difference of body temperature disappeared after the first 2 weeks (P>0.05). Conclusions Reducing the bath frequency form once a day to every third day showed no influence on neonatal skin condition. Meanwhile, it did avoid significant reduce of body temperature after bath. This may help improve healthy skin care of newborns, promote their growth, and at the same time, redistribute the clinical nursing work efficiently.

objective To compare three risk prediction system,the physiological and operative severity score for the enumeration of mortality and morbidity(POSSUM),the Portsmouth POSSUM (P-POSSUM)and the colorectal POSSUM(Cr-POSSUM)for the accuracy in predicting operative mortality of patients of colorectal cancer in a single Chinese referral hospital setting. Methods Data of 903 patients,who undergone surgery for colon and rectal cancers from 1992 to 2005 at Peking University Third Hospital,were enrolled in the study.POSSUM,P-POSSUM and Cr-POSSUM was used respectively to predict the mortality rate.ROC curve was applied to judge the differentiation ability of each score.Model goodness-or-fit was tested by the Hosmer-Lemeshow statistic and subgroup analysis was performed by the ratio of observed to expected deaths(O∶E ratio). Results The actual inhospital mortality in our series was 1.0%(9/903).The oredicted mortality rate by POSSUM,P-POSSUM and Cr-POSSUM were 5.6%,2.8% and 4.8%respectively.These predicted mortality rate were significantly higher than actual mortality of our patients.The O∶E ratio was 0.18,0.35 and 0.2 respectively. Conclusion The predicted mortality rate of POSSUM,P-POSSUM and Cr-POSSUM were significantly higher than actual observed mortality rate in a single Chinese referral hospital for patients of colorectal cancer.

OBJECTIVETo investigate the antitumor effects of intrasplenically transplanted interleukin-18 (IL-18) gene-modified hepatocytes on murine implanted liver carcinoma.

METHODSEmbryonic murine hepatocyte cell line (BNL-CL2) was transfected with a recombinant adenovirus encoding IL-18 and used as delivery cells for IL-18 gene transfer. Two cell lines, BNL-LacZ and BNL-CL2, were used as controls. One week after intrasplenic injection of C26 cells (colon carcinoma line), tumor-bearing syngeneic mice underwent the intrasplenic transplantation of IL-18 gene-modified hepatocyte cell line and were divided into treatment group (BNL IL-18) and control groups (BNL-LacZ and BNL-CL2). Two weeks later, the serum levels of IL-18, interferon-gamma (IFN-gamma), tumor necrosis factor-alpha (TNF-alpha) and nitric oxide (NO) in the implanted liver carcinoma-bearing mice were assayed, the cytotoxicity of murine splenic cytotoxic T-lymphocytes (CTLs) was measured, and the morphology of the hepatic tumors was studied to evaluate the antitumor effects of the approach.

RESULTSIn the treatment group, the serum levels of IL-18, IFN-gamma, TNF-alpha and NO increased significantly. The splenic CTL activity increased markedly (P < 0.01), accompanied by a substantial decrease in tumor volume and the percentage of tumor area and prolonged survival of liver carcinomo-being mice.

CONCLUSIONSIn vivo IL-18 expression by ex vivo manipulated cells with IL-18 recombinant adenovirus is able to exert potent antitumor effects by inducing a predominantly T-cell-helper type 1 (Th1) immune response. Intrasplenic transplantation of adenovirus-mediated IL-18 gene-modified hepatocytes could be used as a targeting treatment for implanted liver carcinoma.
