ABSTRACT
Objective:To adjust the wording and to examine the validity and reliability of the Chinese traditional version of the Body Image Scale (BIS) in patients with rectal cancer.Methods:Totally 180 patients pathologically diagnosed with rectal cancer were selected.The obtained data were divided equally into two parts.Half of them was for item analysis and exploratory factor analysis, and the other half was for confirmatory factor analysis and internal consistency reliability.The criterion validity was tested with the Quality of Life Questionnare-Core30 (QLQ-C30).Twenty-five patients were retested for test-retest reliability with 2 week interval.Results:Two factors were retained after exploratory factor analysis, which could explain 69.1％ of the total variation.And the result of confirmatory factor analysis was that the structure of the scale was stable and achieved goodness of fit (χ2/df=2.32, CFI=0.96, NFI=0.93, IFI=0.96, TLI=0.94, RMSEA=0.078).The scores of total scale and two factors were negatively correlated with the scores of five function domains and overall quality of life of QLQ-C30 (r=-0.27——0.54, Ps＜0.05).In total scale, Cronbach' s α coefficient of total scale was 0.92, while test-retest reliability was 0.88.Conclusion:The Chinese version of BIS showed good validity and reliability for assessment of body image in Chinese patients with rectal cancer.
ABSTRACT
Objective To investigate the biological characteritics of adult animal hepatocytes induced by phenobarbital sodium(PBS) in vivo,and to study the potential value of biological artificial liver of effective hepatocytes.Methods 12 adult male mice,are yandomly divided in to preinducing group and controll group.The preinducing group are intraperitoneally injected PBS per day,45mg/kg for 7 times in total;the controll ware injected NS.after that,we detected the blood serum TP,BUN,CHOL,HDLC.And the same amount of isolative hepatocytes was developed after being developed 48h;MTT was used to investigate the proliferation of hepatocytes after being developed 24h;chromosome was investigated to observe the cell division;and the survival deadline and morphology was also investigated.Results The TP had remarkable difference between the two groups(t=2.678,P
