Abstract:  ObjectiveTo observe the effect of oral nutritional supplementation with complex protein components on improving the nutritional status of patients with digestive tract malignant tumors, so as to provide a basis for improving the comprehensive treatment level of patients with malignant tumors. Methods106 patients with digestive tract malignant tumor in the diet on the basis of application of compound with protein components, self-reflection to observe, to collect oral nutritional supplements before and after the distribution of protein component of total protein, albumin, ferritin, lymphocytes, white blood cells, neutrophils level
for statistical analysis. ResultsUse of oral nutritional supplements after the distribution of protein components, the digestive tract malignant tumor patients with total protein [(56.59±8.74)g/L VS (63.55±7.03)g/L, t=-9.313, P<0.05], albumin[(31.86±4.74)g/LVS (36.16±4.94)g/L, t=-9.919, P<0.05)], ferritin[(0.15±0.05±4.74)g/L VS (0.21±0.11)g/L, t=-5.163, P<0.05)], lymphocyte [(1.41±1.08)×109/L VS (1.99±2.95)×109/L,  t=-2.433, P<0.05], leukocyte[(8.36±3.85)×109/L V(7.41±3.16)×109/L, t=3.007, P<0.05], neutrophil level [(6.52±3.91)×109/L VS (5.41±3.08)×109/L, t=3.476, P<0.05], all indicators improved, and the difference was statistically significant. ConclusionOral nutritional supplement complex protein components can improve the nutritional status and value of patients with digestivetract malignant tumors.
