摘要:

目的    探讨血清白蛋白(ALB)、视黄醇结合蛋白(RBP)、前白蛋白(PA)、纤维连接蛋白(FN)、转铁蛋白(TRF)、瘦素(LP)和氨基酸谱等指标在评估营养不良患儿肠内营养治疗中的意义。方法    选择2009年2月至2010年2月在广州市儿童医院消化科住院的营养不良患儿30例,保健科门诊健康对照组30例,每例均抽血查血常规和ALB、RBP、PA、FN、TRF、LP、三酰甘油(TC)、氨基酸谱分析,营养不良组经10d持续肠内营养后复查上述指标。结果    营养不良组治疗后血清RBP、PA、FN、TRF、LP显著高于治疗前,差异有统计学意义(P < 0.01或P < 0.05);而身高、体重、体重指数(BMI)、肱三头肌皮褶厚度(TSF)、上臂径围(MAC)、上臂肌围(MAMC)、TC、血红蛋白(Hb)、红细胞计数(RBC)、平均血红蛋白浓度(MCHC)、淋巴细胞计数(TLC)、ALB治疗前后比较差异无统计学意义(P > 0.05)。BMI与ALB、RBP、PA、FN、TRF存在正相关性,ALB与RBP、PA、FN、TRF呈正相关,PA与BMI、ALB、RBP、FN、TRF、LP呈正相关,LP与BMI、ALB、RBP、PA等指标呈正相关性。治疗后谷氨酰胺、组氨酸、异亮氨酸、丙氨酸、缬氨酸、精氨酸、亮氨酸、赖氨酸、必需氨基酸(EAA)、必需氨基酸/非必需氨基酸(EAA/NEAA)、支链氨基酸(BCAA)较前明显升高(P < 0.01或P < 0.05),酪氨酸、苯丙氨酸和总芳香族氨基酸(AAA)较治疗前降低(P < 0.01或P < 0.05)。结论    RBP、PA、FN、TRF、LP和血氨基酸谱可作为评估营养不良患儿肠内营养治疗效果的指标。

Abstract:

Objective    To study the significance of serum albumin (ALB),retinol-binding protein (RBP),prealbumin (PA),fibronectin (FN),transferrin (TRF),leptin (LP) and amino acids in malnourished children,to detect sensitive indicators of the effectiveness of enteral nutrition. Methods    30 outpatients from health care clinic from January to Februry 2010 and 30 malnourished inpatients from February 2009 to Februry 2010 were chosen in Department of Gastroenterology,Women and Children’s Medical center. Routine blood test and serum ALB,TRF,PA,RBP,FN,LP,TC,amino acid were determined respectively before continued nasogastric feeding and 10 days later. Results    Serum RBP、PA、FN、TRF、LP were significantly higher than before (P < 0.01 or P < 0.05),no change was observed in height,weight,BMI,TSF,MAC,MAMC,TC,Hb,RBC,MCHC,TLC,ALB (P > 0.05). There were significant positive correlations between BMI and ALB,RBP,PA,FN,TRF;ALB and RBP,PA,FN,TRF;PA and BMI,ALB,RBP,FN,TRF,LP;LP and BMI,ALB,RBP,PA. Glutamine,histidine,isoleucine,alanine,valine,arginine,leucine,lysine,EAA,EAA/NEAA,BCAA were significantly higher than before (P < 0.01 or P < 0.05),tyrosine,phenylalanine and total aromatic amino acids decreased significantly (P < 0.01 or P < 0.05).  Conclusion    RBP,PA,FN,TRF,LP and amino acids were sensitive indicators to assess the effectiveness of enteral nutrition.
