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.
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.
Methods Sixty-six postoperative patients with gastric cancer combined diabetes were divided into 3 groups according to the balanced principle. In the frist group (FD group), FD was the nutrition preparation for 21 patients. In the second group (fresubin group), fresubin and the ordinary insulin injection were the nutrition preparation for 21 patients. In the third group (TPN group), the nutrition preparation came from TPN and the ordinary insulin injection for 24 patients. FD, fresubin or TPN were given at 24 h after operation, the levels of blood glucose for empty stomach, after meal (enteral nutrition or TPN) and the common complications compared among 3 groups of postoperative patients. Results ① In FD group, the levels of blood glucose of postoperative empty stomach and after enteral nutrition were stable with little fluctuation and no insulin was needed with 1 case of hyperglycemia (4.8%). In fresubin group and TPN group, the levels of blood glucose of postoperative empty stomach and after enteral nutrition or TPN were unstable with big fluctuation, with 6 cases (28.6%) and 8 cases (33.3%) of hyperglycemia, 5 cases (23.8%) and 6 cases (25.0%) of hypoglycemia in fresubin group and TPN group, respectively. Compared with fresubin group and TPN group, the rate of pathoglycemia was lower in FD group, the difference had statistical significance separately (Plt;0.05); There was no significant difference between fresubin group and TPN group (Pgt;0.05). ② The rates of infection of incisional wound in FD group (4.8%) and fresubin group (23.8%) were lower than that of TPN group (33.3%), there was significant difference among 3 groups (Plt;0.05); The time of passage of gas by anus in FD group and fresubin group were shorter than that in TPN group (Plt;0.05); There was no significant difference between FD group and fresubin group (Pgt;0.05). There were no significant differences of the rates of abdominal distension or diarrhea among 3 groups (Pgt;0.05). Conclusion Regarding postoperative patients with gastric cancer combined diabetes, in the early time field test group of the nutrition preparation, FD is better than fresubin or TPN, which does not increase the risk of the blood glucose change and have few complications.
Thirty two surgical patients with liver disease (hepatocelluar carcinoma 16, liver cirrhosis 8, obstructive jaundice 8) were studied. All of them were randomly divided into three groups for administration of different kinds of TPN during the postoperative period [group Ⅰ (TPN without fat emulsion), group Ⅱ (TPN with fat emulsion, 1g/kg body weight/day of fat), group Ⅲ (TPN with fat emulsion 2g/kg body weight/day of fat )]. Their liver function test, glucose, lipid metabolism were examined and compared during the period of TPN. Result: ①TB, ALT and AST decreased in group Ⅱ and group Ⅲ (Plt;0.05), but increased in group Ⅰ (Plt;0.05). ②The blood glucose and insulin levels were normal in group Ⅱ and groupⅢ, but showed hyperglycemia and hyperinsulinemia in group Ⅰ (Plt;0.05). ③The serum lipid, lipoprotein, apoliprotein level and LCAT activity returned to normal 6 days after operation in group Ⅱ (Plt;0.05), but not in group Ⅰ and groupⅢ (Plt;0.05). Conclusion: ①TPN with fat emulsion for surgical patients with liver disease can make more improvement on hepatic functions than TPN without fat emulsion. ②1g/kg body weight/day of fat dosage may be suitable for the patients during the period of postoperative TPN.
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.
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.
ObjectiveTo explore influence of different nutritional approaches on liver function in patients after esophagectomy. MethodsA total of 160 patients with esophageal cancer who underwent surgical treatment were divided into a enteral nutrition (EN) group and a total parenteral nutrition (TPN) group according to different medical staff. There were 80 patients in each group. Two and 7 days postoperatively, albumin (ALB), prealbumin (PA), alanine aminotransferase (ALT) and total bilirubin (TB) of the 2 groups were examined to evaluate liver function. ResultsAbnormities in liver function (ALB, PA, ALT, TB) was common phenomenon in esophageal cancer patients, but there was no statistical difference in ALB, PA, ALT, TB on the 2nd postoperative day between the EN group and the TPN group (P > 0.05). On the 7th postoperative day, liver functions were improved than those on the 2nd postoperative day in the two groups. And frequencies of liver function abnormity in the EN group were significantly lower than those in the TNP group (P < 0.05). ConclusionCompared with TPN, EN has advantages in facilitating hepatic protein synthesis and recovery of liver function after esophagectomy.
ObjectiveTo investigate the effects of total parenteral nutrition in neonatal patients and study the nursing methods for these neonates. MethodsWe retrospectively analyzed the clinical data of 70 neonatal patients who accepted total parenteral nutrition in our hospital from October 2010 to October 2011. Physiological indexes were compared before and after total parenteral nutrition. ResultsSignificant improvements in the nutritional status of all children were observed. All patients achieved good efficacy and effective care. ConclusionTotal parenteral nutrition support for critically ill newborns is of great significance, and good caring also plays an important role.
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.
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.
