探討結(jié)構(gòu)脂肪乳在高齡胃腸道腫瘤術(shù)后患者腸外營養(yǎng)的應(yīng)用。選擇2012年1月至2014年10月在北京朝陽醫(yī)院老年病房住院的經(jīng)病理證實(shí)為胃腸道腫瘤的高齡術(shù)后患者68例,隨機(jī)分為結(jié)構(gòu)脂肪乳組(STG組)35例,對(duì)照組(MCT/LCT組)33例,分別給予腸外營養(yǎng)支持治療。監(jiān)測(cè)兩組患者營養(yǎng)指標(biāo)、脂代謝、糖代謝指標(biāo)、肝酶、膽紅素、超敏C反應(yīng)蛋白(hs-CRP)及免疫指標(biāo)變化。術(shù)前及術(shù)后治療前,兩組患者上述指標(biāo)間差異均無統(tǒng)計(jì)學(xué)意義(>0.05)。進(jìn)行6d等氮、等熱量腸外營養(yǎng)支持治療后,兩組的TP、ALB、TC及STG組的PAB、MCT/LCT組的LDL-C顯著高于治療前(<0.05)。STG組營養(yǎng)指標(biāo)顯著高于MCT/LCT組同期水平(<0.05);STG組TC、LDL-C顯著低于MCT/LCT組同期水平(<0.05)。治療3d后,STG組hs-CRP較治療前顯著降低(<0.05),且下降程度大于MCT/LCT組(<0.05)。治療6d后,兩組CD3+、CD4+均較治療前明顯升高(<0.05);STG組CD3+、CD4+及CD4+/CD8+比值顯著高于MCT/LCT組(<0.05)。治療后兩組糖代謝指標(biāo)、肝酶、膽紅素差異無統(tǒng)計(jì)學(xué)意義(>0.05)。結(jié)構(gòu)脂肪乳對(duì)于胃腸道腫瘤術(shù)后高齡老年患者,在促進(jìn)蛋白合成、維持血脂穩(wěn)定、改善炎癥反應(yīng)及免疫抑制方面優(yōu)于常規(guī)MCT/LCT,臨床應(yīng)用安全性較高。

老年人;脂肪乳劑,靜脈注射用;胃腸外營養(yǎng);胃腸腫瘤;T淋巴細(xì)胞亞群

高齡老人罹患胃腸道腫瘤,營養(yǎng)狀況及免疫功能進(jìn)一步下降。脂肪乳作為腸外營養(yǎng)治療中的重要組分,參與供能并影響免疫功能。脂肪乳包括:長鏈甘油三酯(long-chain triglycerides,LCT)及中鏈甘油三酯(medium-chain triglycerides,MCT)。由于二者配比不同,臨床存在不同劑型。本研究旨在探討結(jié)構(gòu)脂肪乳(結(jié)構(gòu)甘油三酯,structured triglycerides,STG)與物理混合的脂肪乳劑(MCT/LCT)對(duì)高齡老年胃腸道腫瘤術(shù)后患者治療效果的影響,為臨床制定合理的營養(yǎng)治療方案提供依據(jù)。

3 討 論

ALB和PAB均在肝合成,是反映機(jī)體蛋白質(zhì)代謝水平的客觀指標(biāo)。它們的半衰期分別為20d和2~3d,因此PAB在判斷蛋白質(zhì)急性變化方面較ALB更為敏感,是評(píng)價(jià)營養(yǎng)狀態(tài)的靈敏指標(biāo)[1]。本試驗(yàn)中,營養(yǎng)支持6d后,STG組TP、ALB、PAB均顯著高于MCT/LCT組,可能與血漿的脂蛋白脂酶活性較高,STG在體內(nèi)水解較快、氧化完全、供能更加迅速有關(guān)。提示STG在蛋白質(zhì)代謝方面較MCT/LCT脂肪乳劑具有更積極的影響。

脂肪乳在提供能量的同時(shí)還提供必需脂肪酸[2],并且,脂質(zhì)參與細(xì)胞膜的結(jié)構(gòu)、功能以及炎癥和免疫調(diào)節(jié)等[3,4],從而成為腸外營養(yǎng)不可缺少的組分。脂肪乳包括LCT脂肪乳劑和MCT脂肪乳劑。LCT脂肪乳劑可為機(jī)體提供能量和必需脂肪酸;MCT脂肪乳劑在體內(nèi)具有水解氧化快、代謝不需要肉毒堿參與及對(duì)免疫系統(tǒng)影響小等優(yōu)點(diǎn)。但由于MCT不含必需脂肪酸,所以常使用物理混合MCT/LCT脂肪乳劑[5,6]。人體對(duì)物理混合MCT/LCT的代謝實(shí)際上是對(duì)MCT與LCT兩種脂肪乳的分別代謝,因此體內(nèi)存在兩者代謝的彼此干擾。當(dāng)MCT水解完成后會(huì)搶占水解酶,使LCT的水解過程變慢,造成血清中TC、LDL-C濃度持續(xù)處于較高狀態(tài)[7]。

STG是將中鏈脂肪酸與長鏈脂肪酸混合、加熱、并在酶的催化下在同一甘油骨架上進(jìn)行結(jié)構(gòu)重組而成,在此過程中TG中的脂肪酸以隨機(jī)方式進(jìn)行結(jié)構(gòu)的再酯化,理論上可避免MCT與LCT兩種脂肪乳代謝的相互干擾,減少肝負(fù)擔(dān)和脂肪酸堆積[8]。本試驗(yàn)應(yīng)用STG營養(yǎng)治療6d后TC、LDL-C顯著低于MCT/LCT組,與STG的水解過程較為平穩(wěn)均勻、代謝更快有關(guān)。證實(shí)STG脂肪廓清速度優(yōu)于MCT/LCT脂肪乳劑。與相關(guān)研究結(jié)果相符[9.10]。

本試驗(yàn),兩組患者在治療后糖代謝指標(biāo)、肝酶、膽紅素差異無統(tǒng)計(jì)學(xué)意義,表明脂肪乳劑對(duì)糖代謝及肝功無不良影響。與其他相關(guān)研究結(jié)果相符[11]。

目前廣泛應(yīng)用的中長鏈脂肪乳為物理混合制劑,其中富含多不飽和脂肪酸(約占60%),易受自由基攻擊產(chǎn)生鏈?zhǔn)椒磻?yīng),引發(fā)脂質(zhì)過氧化,并形成脂質(zhì)過氧化物,對(duì)機(jī)體產(chǎn)生過氧化損傷,進(jìn)一步通過對(duì)線粒體膜蛋白和DNA的作用,導(dǎo)致線粒體損傷和氧化磷酸化功能障礙,引發(fā)能量代謝紊亂,加重機(jī)體應(yīng)激狀態(tài)[12]。在STG中多不飽和脂肪酸僅為38%。其結(jié)構(gòu)特點(diǎn)決定了它能以等速釋放長鏈脂肪酸和中鏈脂肪酸入血[13,14]。在本研究中,術(shù)后兩組患者h(yuǎn)s-CRP較術(shù)前明顯升高,說明手術(shù)創(chuàng)傷對(duì)機(jī)體產(chǎn)生了明顯的急性炎性反應(yīng)。營養(yǎng)治療3d后,STG組患者h(yuǎn)s-CRP水平顯著降低,且明顯低于MCT/LCT組,表明STG對(duì)機(jī)體造成的應(yīng)激反應(yīng)影響較小。

一些臨床和實(shí)驗(yàn)研究提示,輸注脂肪乳劑有損于機(jī)體的免疫功能,并增加感染的危險(xiǎn)性,其機(jī)制主要與脂肪酸有關(guān)[15]。脂肪酸的改變可影響這些免疫調(diào)節(jié)因子的產(chǎn)量和活性[16]。T淋巴細(xì)胞亞群中CD3+代表細(xì)胞免疫的總體水平,CD3+減少表示機(jī)體細(xì)胞免疫功能總體減弱;CD4+為輔助T細(xì)胞,輔助B細(xì)胞分化產(chǎn)生抗體,分泌淋巴因子激活其他細(xì)胞產(chǎn)生炎性反應(yīng),并介導(dǎo)其作用;CD8+為免疫抑制細(xì)胞,輔助其他免疫細(xì)胞的功能,抑制抗體的合成分泌及T細(xì)胞增殖。本研究結(jié)果顯示,兩組術(shù)后治療前CD3+、CD4+、CD8+均有不同程度下降,此后均逐步回升,治療6d后STG組CD3+、CD4+較MCT/LCT組明顯升高,CD4+/CD8+亦明顯高于MCT/LCT組,提示STG對(duì)機(jī)體細(xì)胞免疫功能影響相對(duì)小。結(jié)合此時(shí)STG組hs-CRP較MCT/LCT組下降顯著,證實(shí)炎性反應(yīng)的減輕伴隨著免疫功能的恢復(fù)。

總之,本試驗(yàn)可見,與傳統(tǒng)的MCT/LCT相比,STG對(duì)于胃腸道腫瘤術(shù)后高齡老年患者在促進(jìn)蛋白合成、維持血脂穩(wěn)定、改善手術(shù)應(yīng)激導(dǎo)致的炎癥反應(yīng)及免疫抑制方面優(yōu)于常規(guī)MCT/LCT,對(duì)糖代謝、肝酶、膽紅素代謝影響不大,臨床應(yīng)用具有一定優(yōu)勢(shì),安全性較高。

Application of structured triglycerides for parenteral nutrition in elderly patients after gastrointestinal tumor surgery

BAI Xi, SUN Qian-Mei*

(Department of General Medicine, Beijing Chaoyang Hospital, Capital Medical University, Beijing 100020, China)

To determine the efficiency of structured triglycerides [STG, with the ratio of medium-chain triglycerides to long-chain triglycerides (MCT/LCT) accounting for 36% to 64%] for total parenteral nutrition (TPN) in the elderly patients with gastrointestinal (GI) tumor operation.Sixty-eight elderly pathologically-identified GI tumor patients undergoing surgical treatment and then being admitted to the Department of Geriatrics of our hospitalfrom January 2012 to October 2014 were recruited in this study. The cohort was randomly divided into 2 groups, STG group (=35) and MCT/LCT group (the ratio accounting for 50% to 50%,=33). They were all given TPN for 6 d after their operations. The parameters of nutrition, lipid metabolism, glucose metabolism, liver enzymes, bilirubin, high sensitivity C-reactive protein (hs-CRP) and immunologic profiles at baseline and 3 and 6d after treatment were measured and recorded respectively.There was no significant difference in the above-mentioned parameters between the 2 groups before and immediately after surgery. The levels of total protein (TP), albumin (ALB) and total cholesterol (TC) in the both groups, that of prealbumin (PAB) in the STG group, and that of low-density lipoprotein-cholesterol (LDL-C) in the MCT/LCT group were significantly increased after 6 days’ isonitrogen isocaloric nutritional support (<0.05). The nutritional parameters were significantly higher in the STG group than in the MCT/LCT group at the same time points (<0.05), but the levels of TC and LDL-C were remarkably lower in the former than in the latter. At 3d after treatment, the level of hs-CRP was reduced significantly in STG group compared to that of before treatment (<0.05), and the reduction was greater than that in the MCT/LCT group (<0.05). The CD3+and CD4+cell counts were increased significantly than before treatment in both groups (<0.05), but the counts of CD3+and CD4+cells and the ratio of CD4+/CD8+were much higher in the STG group than in the partner one (<0.05). No statistical difference was seen in glucose levels, liver function and bilirubin level between the 2 groups after treatment (>0.05).STG is superior to the conventional MCT/LCT in promoting protein synthesis, stabilizing lipid profiles, ameliorating the inflammatory reaction, as well as regulating the immune system, for TPN in the elderly patients after GI tumor operation, and also has higher safety in clinical application.
