Objective:The aim of this study was to explore the applicative effects of immune-enhanced enteral nutrition(Supportan) in preoperative preparation for patients with colorectal carcinoma.Methods:56 colorectal carcinoma patients with mid-severe malnutrition were randomly divided into two groups,experiment group and control group,each of 23.Experiment group was administrated with immune-enhanced enteral nutrition(Supportan).Control group was administrated with common enteral nutrition(Nutrison Fibre).Nutritional status,immunological function,inflammatory factor and the satisfaction of colon were observed.Results:After enteral nutrition,the plasma albumin,prealbumin,IgG,IgM,CD4+ T cells and the ratio of CD4+/ CD8+ were higher in experiment group than in control group and TNF-?,IL-6 and PGE2 were lower in experiment group than in control group.Conclusions:Immune-enhanced enteral nutrition(supportan) can improve nutritional status,strengthen immunological function,and decrease inflammatory reaction in the colorectal carcinoma patients with mid-severe malnutrition.

Objective: To explore the reliability and validity of the Chinese Pediatric Quality of Life Inventory（PedsQL）in influenza children. Methods: From January 2017 to February 2018,we selected laboratory-diagnosed influenza cases and healthy children according to age and gender ratio by stratified random sampling and systematic sampling method. We employed Chinese version of PedsQL 4.0 to investigate their quality of life,used Cronbach's α to evaluate the reliability,and used Pearson correlation coefficient, t-test,confirmatory factor analysis（CFA）and ROC curve to evaluate the validity. Results: Totally 300 influenza cases and 300 healthy children were surveyed,with 294（98.00%）and 295（98.33%）valid questionnaires recovered. The general Cronbach's α was 0.89,and the Cronbach's α of each dimension ranged from 0.79 to 0.84. The Pearson correlation coefficients between the items and their belonged dimension ranged from 0.537 to 0.755,between the items and other dimension ranged from 0.203 to 0.384. The CFA resulted in RMSEA of 0.06,GFI of 0.88,AGFI of 0.90,CFI of 0.91 and NFI of 0.89. The scores in total and in all the dimensions in influenza cases were significantly different with those in healthy children（P<0.05）. Taking the scores in influenza cases as a golden standard,the area under the ROC curve was 0. 985（P<0.05）,the sensitivity was 0.92,and the specificity was 0.95. When the limit score was 82.18,the Youden index was the largest. Conclusion The Chinese version of PedsQL4.0 has good reliability and validity, which can be applied to quality of life assessment in children.
