To study the effects of arginine supplementation in total parenteral nutrition (TPN) on lymphocytic immune function in postoperative patients with gastric cancer. Thirty six patients with gastric cancer receiving TPN were eligible for entry into randomized and prospective clinical trial of the study. T cell subsets, NK cell activity, plasma IL-2 content and peripheral blood CD25 were measured in before and after parenteral nutrition of the patients. Results: usual TPN could not improve lymphocytic immunosuppression of postoperative patients with gastric cancer. The patients receiving arginine supplementation in TPN might enhance lymphocytic immune function by increasing CD4 level, IL-2 production and NK cell activity, but there was no significant effect of arginine on CD25 expression. Conclusion: there are some effects of supplement with arginine on releasing of the cellular immunosuppression and restoring of lymphocytic immune function.
Objective To research the effects of recombinant growth hormone (rhGH) with total parenteral nutrition (TPN) on nitrogen balance and nutritional state of the patients following major abdominal surgery. Methods We randomly selected 45 patients receiving TPN after major abdominal surgery and distributed them to study group (rhGH+TPN, n＝30) and control group (TPN only, n＝15). For 7 days after operation, every one was given rhGH 4u or replaced by hypodermic injection of normal saline (control group). Results TPN+rhGH promoted the rehabilitant of nitrogen balance, heightened the level of plasma albumin and transferrin and increased the weight and creatinin/height index (CHI), but the thickness of triceps skin fold (TSF) had no significant change in patients following major abdominal surgery. Conclusion The rhGH can improve the effects of TPN.
In order to investigater the effect of nutritional support on nutrients metabolism after liver resection,we researched into the hepatectomy and total parenteral nutrition model in rats.The features of the model were no fasting before surgery,10% glucose subcutaneous injection prior to operation avoiding of blood loss and shortening of the surgical process.The 7-day mortality was markedly decreased.Anesthetized with phenobarbital(25mg/kg) injection in combination of ether inhalation,the rats recovered quickly from anesthesia and developed almost no infection of the respiratory tract after hepatectomy.The rats were supplied parenterally energy of 573kJ/kg and a marked improvement in survival was achieved after liver resection.By applying dual preventive rotation equipment of protective spring and IN-Stopper,nutrient solution could be safely infused.
Objective To evaluate the effectiveness and safety of total enteral nutrition (TEN) versus total parenteral nutrition (TPN) in patients with severe acute pancreatitis (SAP). Methods The databases such as Pubmed (1996 to June 2011), EMbase (1984 to June 2011), Cochrane Central Register of Controlled Trials of The Cochrane Library (Issue 6, 2011) and CBM (1978 to June 2011) were electronically searched, and the relevant references of the included papers were also manually searched. Two reviewers independently screened the trials according to inclusion and exclusion criteria, extracted the data, and assessed the methodology quality. Meta-analyses were performed using the Cochrane Collaboration’s RevMan 5.1 software. Results Seven randomized controlled trials (RCTs) involving 379 patients with SAP were included. The results of meta-analyses showed that compared with TPN, TEN could significantly reduce the risk of mortality (RR=0.33, 95%CI 0.20 to 0.55, Plt;0.000 1), pancreatitis-related infections (RR=0.35, 95%CI 0.25 to 0.50, Plt;0.000 01), required rate of surgical intervention (RR=0.43, 95%CI 0.23 to 0.82, P=0.01), and incidence of multiple organ failure (MOF) (RR=0.28, 95%CI 0.17 to 0.46, Plt;0.000 01). There was no significant difference in the nutrition strategies associated complications between TPN and TEN (RR=1.16, 95%CI 0.42 to 3.22, P=0.78). Conclusion Meta-analyses show that compared with TPN, TEN can reduce the risk of mortality, pancreatitis-related infections, required rate of surgical intervention, and incidence of MOF; and it will not increase the nutrition strategies associated complications. Consequently, TEN should be considered a better choice for SAP patients as early as possible.

Methods : A total of 54 postoperative patients with gastrointestinal malignancy were randomly divided into EN group and parenteral (PN) group. Both groups received isocaloric and isonitrogen nutrition support. The serum albumin, transferrin, prealbumin and liver and renal function were measured using standard techniques. The gastrointestinal function and postoperative complications were evaluated. Results : After nutrition support, serum albumin was not significantly different between two groups. Compared with PN group, serum transferrin and prealbumin level significantly increased in EN group (P＜005). The gastrointestinal function in EN group resumed earlier than that in PN group. There was also no difference in liver and renal function and postoperative complications between two groups. Conclusion : The application of early enteral nutrition support is beneficial to the recovery of the gastrointestinal cancer patients after surgery.
ObjectiveTo study the protective effect of hepatocyte growth factor(HGF) on grafted mucous membrane of transplanted small bowel.MethodsTotal small bowel transplantation was made in inbred Wistar (RT1k) rats heterotopically,either total parenteral nutrition (control group,n=10) or hepatocyte growth factor supplemented TPN (HGF group,n=10) was given to the recipients from the 2nd day to the 10th day postoperatively. Morphological parameters of the transplanted intestinal mucosa, such as mucosal villous height, villous width, crypt depth, mucosal thickness and villous surface area were observed. Variation of ultrastructure of transplanted epithelial cells was observed. Composition of mucosal protein and DNA content were tested. ResultsComparison between HGF group and the control group were as follows. Mucosal villous height (298.79±22.31） μm vs （176.45±14.62） μm, P=0.001, villous width (107.46±12.34） μm vs （74.20±16.85） μm, P=0.004, crypt depth (104.56±11.17） μm vs （74.45±8.34） μm, P=0.000 5, mucosal thickness (409.53±35.83） μm vs （259.38±24.65） μm, P=0.003, and villous surface area (0.101±0.011) mm2 vs (0.041±0.005) mm2, P=0.001 were found significantly increased in HGF group compared with control group, there were no obvious difference decrease as compared to pretransplant parameters.Mucosal protein composition was higher in HGF group than that in control group （89.65±9.28) mg/g wet wt vs (53.73±11.45) mg/g wet wt, P=0.012, baseline (92.64±10.52) mg/g wet wt, nearly equal to baseline; DNA composition was also high in HGF group （0.89±0.09) mg/g wet wt vs (0.51±0.06) mg/g wet wt, P=0.008, baseline (0.91±0.09) mg/g wet wt. Nearly normal ultrastructure of the graft was maintained in HGF group, atrophied microvilli and broken mitochondrial crista were observed in control group.ConclusionHepatocyte growth factor can improve mucosal structure, preserve enterocyte ultrastructure of isograft after small bowel transplantation in rat.
Objective To investigate the influence on the postoperative recovery for giving either total parenteral nutrition （TPN） or early enteral nutrition (EEN) to patients with gastric cancer after total gastrectomy. Methods Eighty-six patients with gastric cancer undergone total gastrectomy were divided into TPN group (n=31) and EEN group (n=55). Patients in TPN group received TPN support via vena cava (internal jugular vein or subclavian vein), while patients in EEN group received early feeding through the naso-intestinal tube, which was placed during operation, and volume of enteral nutrition (fresubin) was increased daily, full enteral nutrition was expected on day 3-5. Nutrition status after operation, postoperative plasma albumin (Alb), the time of passing gas or stool, the time of oral intake, hospital stay and any postoperative complications were recorded and analyzed. Results There were no significant differences between two groups (Pgt;0.05) in postoperative plasma Alb level, the time of passing gas or stool, postoperative complications rate or hospital stay. However, in the TPN group, the time of oral intake was shorter than that in EEN group (P=0.004). Conclusions Both TPN and EEN are the suitable nutritional methods for patients with gastric cancer after total gastrectomy, and with no detectable difference. For patients with high risk, such as severe malnutrition, naso-intestinal tube should be placed for EEN.
Objective To study glutamine (GLN) and cholecystokinin (CCK) effects on prevention of cholestasis in total parenteral nutrition (TPN). Methods White rabbits were choosed as TPN models, which were divided into four groups, group 1, TPN only (n＝10); Group 2, TPN plus GLN administration (n＝10); Group 3, TPN plus CCK (n＝10); Group 4, TPN plus GLN and CCK administration. Bile components were assayed and the structural change in gallbladder and liver were observed under light and election microspes at the forth and eighth week. Results Increasing of bilirubin and cholesterol was observed in the 1st and 2nd groups at the forth week, but increasing in the 3rd group was observed at the eighth week. The 4th group was normal. Changes of gallbladder and liver structure in 1st and 3rd group occured at the forth week. Changes of 2nd group occured at the eighth week. No structural change was found in the 4th group. Conclusion The test prove that cholestasis would occure during TPN and become serious with time prolonging. Integrity and function of gallbladder-wall tissue cell could be defended and sustained by applying GLN, but there is no direct preventing action. There is apparent cholecy stokinetic and cholagogic fundations by applying CCK. But CCK would lose its function if gallbladderwall was damaged. The test prove that TPN+GLN+CCK is the best way to prevent cholestasis during TPN.
ObjectiveTo evaluate the value of omega-3 fish oil fat emulsion in parenteral nutrition support after radical resection of gastric cancer patients.MethodsThe clinical data of 80 patients in Tongling Peopl’s Hospital undergoing radical resection of gastric cancer from March 2018 to September 2019 were enrolled by retrospective method. Of them, 40 patients were treated with routine parenteral nutrition (control group) and 40 patients were treated with extra 100 mL omega-3 fish oil fat emulsion after operation (observation group). Nutritional and stress indicators included blood total albumin (TP), albumin (ALB), c-reactive protein (CRP), and procalcitonin (PCT) on one day before operation, and 1st, 3rd, and 7th day after operation were collected. The collected indexes of liver function included blood cholesterol (CHO), triglyceride (TG), total bilirubin (TBIL), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and gamma glutamyl transpeptidase (γ-GT) on one day before operation, and 3rd and 7th days after operation.Results① Nutritional indicator. There was no significant differences in TP and ALB levels between the two groups on one day before operation, and on the 1st, 3rd, and 7th day after operation (P>0.05). In the same group compared with one day before operation, the average TP level of the control group and the observation group decreased on the 1st, 3rd, and 7th day after operation (P<0.05), and in the control group and the observation group, the ALB level decreased on the 1st day after operation (P<0.05), and increased on the 7th day after operation (P<0.05). ② Stress index. There was no significant difference in CRP and PCT levels between the two groups on one day before and one day after operation (P>0.05), and the CRP and PCT levels in the observation group were lower than those in the control group on the 3rd day and 7th day after operation (P<0.05). Compared with the CRP and PCT levels on the one day before operation, the average CRP and PCT levels in the observation group and the control group increased on the 1st, 3rd, and 7th day after operation (P<0.05). ③ Liver function index. There was no significant differences in CHO, TG, and γ-GT levels between the two groups on one day before operation and the 3rd day after operation (P>0.05), but the above indexes of observation group were lower on the 7th day after operation than those of the control group (P<0.05). There was no significant differences on TBIL, ALT, and ALP levels between the postoperative observation group and the control group (P>0.05). Compared with one day before operation in the same group, there was no significant difference on CHO and ALP levels on 3rd and 7th day after operation in both the observation group and control group (P>0.05). There was no significant differences in TG and TBIL levels in the observation group on 3rd and 7th day after operation (P>0.05), but the TG and TBIL levels in the control group were increased on 7th after operation (P<0.05), and the ALT and γ-GT levels in the observation group and the control group on 7th day after operation were increased in the same group compared with one day before operation (P<0.05).ConclusionParenteral nutrition with omega-3 fish oil fat emulsion do not improve the recent postoperative nutritional status, but reduce the inflammatory stress response and protecte liver function in patients with gastric cancer after operation.
Objective To evaluate the effectiveness and safety of early enteral nutrition (EN) versus total parenteral nutrition (TPN) after pancreaticoduodenectomy (PD). Methods Such databases as MEDLINE, EMbase, The Cochrane Library, CBM, VIP, CNKI were electronically searched to collect the randomized controlled trials (RCTs) about EN versus TPN after PD published from 2000 to March 2010. The quality of the included trials was assessed according to the inclusive and exclusive criteria, and the data were extracted and analyzed by using RevMan 5.0 software. Results A total of 4 RCTs involving 322 PD patients were included. The meta-analysis showed that the EN (the treatment group) was superior to the TPN (the control group) in the average postoperative hospital stay (MD= –2.34, 95%CI –3.91 to –0.77, Plt;0.05), the total incidence rate of complication (RR=0.75, 95%CI 0.57 to 0.99, P=0.04), the recovery time of enterocinesia (MD= –29.87, 95%CI –33.01 to –26.73, Plt;0.05) and the nutrition costs (MD= –30.51, 95%CI –35.78 to –25.24, Plt;0.05); there were no differences in mortality (RR=0.23, 95%CI 0.03 to 2.03, P=0.19), pancreatic leakage (RR=0.78, 95%CI 0.45 to 1.35, P=0.38), infectious complications (RR=0.71, 95%CI 0.43 to 1.18, P=0.19), non-infectious complications (RR=0.78, 95%CI 0.5 1 to 1.20, P=0.26) and postoperative serum albumin level (MD= –0.79, 95%CI –2.84 to 1.27, P=0.45). Conclusion Compared with total parenteral nutrition, the enteral nutrition used earlier after pancreatoduodenectomy shows significant advantages. But more reasonably-designed and double blind RCTs with large scale are expected to provide high quality proof.
