上消化道和下消化道恶性肿瘤患者营养状况评定比较

The differences between upper and lower gastrointestinal maliganacies in nutritional assesements

采用不同的营养评定方法(IBW％、ALB、PA、CHI％及血清氨基酸浓度测定),分别对23例上消化道恶性肿瘤患者(U组)和20例下消化道恶性肿瘤患者(L组)检测术前营养状况。结果提示:1.IBW％、ALB、PA均不能早期反映营养不良,但可反映两组的营养状况差异;2.CHI％能反映U组的营养不良,但不能反映L组的营养缺陷;3.血清氨基酸浓度测定可反映两组的营养不良;4.多数类别的氨基酸浓度变化与营养不良状况呈平行关系,AAA及met浓度变化与营养状况无关。

23 patients with upper gastrointestinal maliganacies(U-group) and 20 patients with lower gastrointestinal maliganacies(L-group) were measured by height, body weight, serum albumin, serum pre-albumin, 24 hours urine creartine and serum amino acids. The results of the study were that: (1) the IBW%, ALB and PA couldn' t reflect on early malnutrition, but there were significant differences of nutri-tional status between two groups; (2)the CHI% could reflect on malnutrition in U-group, but it couldn't reflect on malnutrition in L-group; (3) the concentrations of serum amino acids could reflect on malnutri-tion in both two groups; (4) the concentrations of most amino acids were related to nutritional status, but the concentrations of AAA and Met were not related to nutritional status.
