[摘要] 目的 研究血清白蛋白(ALB)、前白蛋白(PA)、视黄醇结合蛋白(RBP)、转铁蛋白(TRF)在胃癌术后患者肠外营养支持中的营养监测价值。 方法 选择2016年6月~2017年6月青岛大学附属医院胃肠外科行胃癌手术的患者80例,所有患者于胃癌手术后第1天开始全肠外营养支持(≥5 d)。分别收集入院常规检查时(术前)、术后第1天、术后第6天的血清标本,并检测血清ALB、PA、RBP以及TRF水平的变化。 结果 ①术前、术后第1天、术后第6天,血清ALB、PA、RBP以及TRF的浓度比较,差异有高度统计学意义(P < 0.01);②术后第1天,血清ALB、PA、RBP以及TRF较术前均下降,差异有高度统计学意义(P < 0.01);③术后第6天,血清ALB、PA、RBP以及TRF较手术后第1天均升高,差异有高度统计学意義(P < 0.01);④术后第6天,PA、RBP与术前比较,差异无统计学意义(P > 0.05),ALB、TRF与术前比较,差异有统计学意义(P < 0.05)。 结论 血清ALB、PA、RBP以及TRF可以反映患者营养状况,对胃癌术后患者应用肠外营养支持有一定指导作用。

[Abstract] Objective To study the nutritional monitoring value of serum albumin (ALB), prealbumin (PA), retinol binding protein (RBP), and transferrin (TRF) in parenteral nutrition support for patients after gastric cancer surgery. Methods From June 2016 to June 2017, 80 patients with gastric cancer surgery stayed in the Gastrointestinal Surgery, the Affiliated Hospital of Qingdao University were selected, and they were started with total parenteral nutrition (TPN) (≥5 d) on the first day after gastric cancer surgery. The serum specimen of blood routine examinations on the day of hospital admission (before surgery), on the first day and the sixth day after surgery were collected respectively, and changes of ALB, PA, RBP and TRF level in serum were measured respectively as well. Results ①Concentration changes of ALB, PA, RBP and TRF before surgery, on the first day after surgery and the sixth day after surgery were comparerd, the differences were statistically significant (P < 0.01). ②On the first day after surgery, ALB, PA, RBP and TRF dropped compared with before surgery, the differences were statistically significant (P < 0.01). ③On the sixth day after surgery, ALB, PA, RBP and TRF climbed up compared with the first day after surgery, the differences were statistically significant (P < 0.01). ④On the sixth day after surgery, PA and RBP were compared with before surgery, the differences were not statistically significant (P > 0.05), and ALB and TRF were compared with before surgery, the differences were statistically significant (P < 0.05). Conclusion Serum ALB, PA, RBP and TRF can reflect patients′ nutritional status and they play a guiding role in parenteral nutrition support for patients after gastric cancer surgery.

随着生活节奏的加快和饮食结构的复杂化,胃癌发病率已越居恶性肿瘤发病率前列[1],中国是胃癌的高发区,每年胃癌新发病例约占世界总发病例数的42%[2]。胃癌的主要治疗方法是手术治疗,手术会导致机体高代谢状态从而导致营养不良和免疫功能的损害[3]。营养不良同时可导致一些并发症的发生,增加患者的住院时间、住院费用和死亡率[4],所以,营养支持至关重要。目前临床上常用的营养支持方法有肠内营养(enteral nutrition,EN)和肠外营养(parenteral nutrition,PN),其中PN是指由于胃肠道功能紊乱或胃肠道切除而不经过胃肠道途径供给患者营养物质的支持方法[4],全肠外营养(total parenteral nutrition,TPN)是指营养物质完全通过静脉途径供给的支持方法。虽然营养评定没有金标准,但仍有多种营养筛选和评估指标[5-6]。血清蛋白可作……
