术前肠内营养支持联合改良Ivor-Lewis手术治疗食管癌对肺功能及外周血GATA3、Foxp3 mRNA表达的影响

Effect of preoperative enteral nutritional support combined with modified Ivor-Lewis surgery for esophageal cancer on lung function and GATA3 and Foxp3 mRNA expression in peripheral blood

目的观察术前肠内营养支持联合改良Ivor-Lewis手术治疗食管癌对肺功能及外周血GATA结合蛋白3(GATA3)、叉头蛋白P3(Foxp3)mRNA表达的影响。方法选取2022年1月至2023年10月进行改良Ivor-Lewis手术治疗的60例食管癌患者为对象,采用简单随机法分为两组。对照组术前常规饮食,观察组术前给予肠内营养支持,分析两组效果。结果两组术后1周一秒用力呼气容积/用力肺活量(FEV1/FVC)、FVC、FEV1及外周血GATA3、Foxp3 mRNA表达均较入院时降低(P<0.05)。观察组术后1周肺功能、外周血GATA3、Foxp3 mRNA表达与对照组比较,差异无统计学意义(P>0.05)。两组术后1周白蛋白、前白蛋白、血红蛋白、转铁蛋白、PNI及对照组体质量、体质量指数均较入院时降低(P<0.05)。观察组术后1周白蛋白、前白蛋白、血红蛋白、转铁蛋白、PNI均高于对照组(P<0.05)。观察组通气时间、排便时间、引流管留置时间、住院时间及并发症发生率与对照组比较,差异无统计学意义(P>0.05)。结论术前肠内营养支持联合改良Ivor-Lewis手术治疗食管癌可改善术后机体营养状态,对患者术后肺功能及外周血GATA3、Foxp3 mRNA表达的影响较小。

Objective To observe the effect of preoperative enteral nutritional support combined with modified Ivor-Lewis surgery for esophageal cancer on lung function and mRNA expression of GATA-binding protein 3(GATA3)and forkhead protein P3(Foxp3)in peripheral blood.Methods Sixty esophageal cancer patients who underwent modified Ivor-Lewis surgery in our hospital from January 2022 to October 2023 were selected and divided into two groups by simple random method.The control group was given conventional diet before operation,and the observation group was given enteral nutrition support before operation.The two groups were compared in terms of nutritional support.Results Both groups showed significantly decreases in one-second exertion expiratory volume/exertion lung volume(FEV1/FVC)(P<0.05),FVC(P<0.05),FEV1(P<0.05)and the levels of peripheral blood GATA3(P<0.05),Foxp3 mRNA(P<0.05)expression compared with those at admission(P<0.05),but no significant differences in pulmonary function(P>0.05),peripheral blood GATA3(P>0.05),and Foxp3 mRNA(P>0.05)expression between them at 1 week postoperatively.Both groups exhibited significantly lower levels of albumin,prealbumin,haemoglobin,transferrin,PNI and body mass and body mass index at admission as compared to those at one week after surgery(P<0.05).The observation group showed significantly higher levels of albumin,prealbumin,haemoglobin,transferrin,and PNI at 1 week postoperatively(P<0.05),but no significant differences in ventilation time,defecation time,drain retention time,hospitalisation time,and complication rate as compared to the control group(P>0.05).Conclusion Preoperative enteral nutritional support combined with modified Ivor-Lewis surgery for esophageal cancer improves postoperative nutritional status,and renders less effect on postoperative lung function and peripheral blood GATA3 and Foxp3 mRNA expression.
