Objective To investigate the effect of mesenteric lymphatic duct liagtion and glutamine enteral nutrition on intestine and distant organs in intestinal ischemia/reperfusion injury. Methods Forty male SD rats undergoing gastrostomy were randomly assigned into 5 groups (n=8): sham operation group, normal enteral nutrition group, normal enteral nutrition+lymphatic duct ligation group, glutamine group and glutamine+lymphatic duct ligation group. Sham operation group only received laparotomy after 7 days of full diet, the other four groups were subjected to 60 min of intestinal ischemia after 7 days of enteral nutrition, and the two lymphatic duct ligation groups were plus mesenteric lymphatic duct ligation. The original nutrition continued 3 days after reperfusion. Intestinal permeability was detected on day 1 before reperfusion, day 1 and 3 after reperfusion. Intestinal morphology was observed, endotoxin, D-lactate and diamine oxidase levels in serum, and apoptotic index in lung tissue were detected on day 3 after reperfusion. Results The intestinal permeability in each group was significantly increased on day 1 after reperfusion (Plt;0.05), and which in normal enteral nutrition+lymphatic duct ligation group and glutamine+lymphatic duct ligation group were significantly decreased on day 3 after reperfusion (Plt;0.05). The mucosal thickness and villus height of ileum and mucosal thickness of jejunium in glutamine+lymphatic duct ligation group were significantly higher than those in other groups (Plt;0.05), and villus height of ileum in glutamine group was higher than that in normal enteral nutrition group (Plt;0.05); those morphology indexes in normal enteral nutrition+lymphatic duct ligation group were higher than those in normal enteral nutrition group, but there was no statistical signification (Pgt;0.05). Apoptosis index of lung tissue in lymphatic duct ligation groups was significant lower than that in no-ligation groups (Plt;0.05). Levels of endotoxin, D-lactate, and diamine oxidase in lymphatic duct ligation groups had downward trends compared with no-ligation groups, but there was no statistical signification (Pgt;0.05). Conclusions Intestinal ischemia/reperfusion injury of rats can cause intestinal permeability increase, bacterial endotoxin translocation and systemic inflammatory response. Mesenteric lymphatic duct ligation and glutamine enteral nutrition intervention can weak lung tissue damage, increase thickness of intestinal mucosa, maintain intestinal barrier function, reduce endotoxin translocation and attenuate systemic inflammatory response. Enteral nutrition with glutamine was better than normal enteral nutrition.
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.
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 study the current clinical application and advancement of microbioecological preparation. Methods Literatures about microbioecological preparation published in China and abroad were collected and reviewed. Results The microbioecological preparation has been widely used at present. It is used to rebuild a balanced microbial population in human body, particularly in intestinal, to promote the stability of internal environment, control dysbacteriosis and to treat a variety of gastrointestinal diseases associated with ectopic microbial population. Conclusion Although microbioecological preparation has been widely used in clinical settings, its effect yet should be further supported and evaluated both by large sample research in randomized double-blind control trails and evidence-based medicine.
ObjectiveTo compare the clinical effects of enteral nutrition via stoma of jejunum or nasal-jejunum tube after Whipple procedure. MethodsEighty-seven patients performed Whipple procedure were divided into nasaljejunum tube group(n=47)and stoma of jejunum group(n=40)according to the different enteral nutrition methods. The adverse reactions such as vomiting, abdominal distension, pharyngeal pain, and hypostatic pneumonia, anastomotic leakage, hospital stay, hospitalization expenses, and serum glucose and electrolyte(CL-, Na+, K+)on day 1, 3, 5 after operation were compared between two groups. ResultsCompared with the nasal-jejunum tube group, the rates of adverse reactions and hypostatic pneumonia were more lower(P < 0.05), the hospitalization expense was more less (P < 0.05) in the nasal-jejunum tube group. The rate of anastomotic leakage and hospital stay had no significant differences between the nasal-jejunum tube group and stoma of jejunum group(P > 0.05). The differences of serum glucose and electrolyte(CL-, Na+, K+)on day 1, 3, 5 after operation were not statistically significant between two groups(P > 0.05). ConclusionsEnteral nutrition via the stoma of jejunum after Whipple procedure has some better clinical effects in reducing adverse reactions such as vomiting, abdominal distension, pharyngeal pain, hypostatic pneumonia. The hospitalization expenses are decreased. There are no obvious effects on the hospital stay, blood glucose and electrolyte concentration on day 1, 3, 5 after operation.
【Abstract】ObjectiveTo investigate the effects of rhGH on hypoalbuminemia in cirrhotic rats after partial hepatectomy. MethodsThirty rats were randomly divided into normal control group (n=6), liver cirrhosis group (LC group, n=6), liver cirrhosis and hepatectomy group (LCH group,n=6), PN (parenteral nutrition) group (n=6， given PN after hepatectomy) and rhGH+PN group (n=6,given rhGH and PN after hepatectomy). Liver function and blood glucose were measured. The expression of ALB mRNA was detected by RTPCR. Liver Ki67 immunohistochemistry was studied.

Objective To evaluate the clinical curative effect of early enteral nutrition （EN） in gastric cancer patients after operation and its safety. Methods One hundred and eighty patients with gastric cancer diagnosed and underwent surgical treatment in gastrointestinal surgery center， West China Hospital from February 2011 to December 2011 were studied prospectively， who were randomly divided into EN group （n=91） and parenteral nutrition （PN） group （n=89）. The nutrition state， rehabilitation， hospital stay， cost of nutrition in hospital， and complications were observed. Results ①According to the postoperative serum nutrition index， there were no significant differences in the prealbumin， hemoglobin， and ratio of albumin to globulin in two groups （P＞0.05）， but the albumin level in the EN group was significantlyhigher than that in the PN group （P=0.047）. ②According to the postoperative rehabilitation index， the first ambulation time （P=0.011）， first intake time （P=0.000）， first nasogastric tube away time （P=0.013）， first drainage tube away time （P=0.021）， and first urinary catheter away time （P=0.002） in the EN group were significantly shorter than those in the PN group. The difference of the first anus exhaust time was not statistically significant in two groups （P=0.083）. ③The cost of nutrition in hospital in the EN group was significantly less than that in the PN group （P=0.017）. The postoperative hospital stay and total complication rate were not significant differences in two groups （P＞0.05）. Conclusion Early postoperative EN is effective， economic， practical， which might be superior to PN.
ObjectiveTo investigate the effect of enhanced recovery after surgery (ERAS) combined with preoperative oral nutrition supplement (EnsourceTM) in patients with rectal cancer and its effect on postoperative stress response.MethodsFrom January 2018 to August 2018, 80 patients with laparoscopic assisted radical resection of rectal cancer in our hospital were divided into two groups according to different perioperative management. Forty patients who had used enhanced recovery after surgery combine preoperative application of tumor total nutrition formula enteral nutrition solution were as observation group, while other 40 patients who only had used enhanced recovery after surgery in perioperative as control group. We observed the stress response (mean systolic blood pressure, mean diastolic blood pressure, mean heart rate, mean blood oxygen saturation, pain score and fasting blood glucose) at 24 hours after surgery and the time of the first anal exhaust, complication rate, hospitalization time, and hospitalization cost after surgery in both groups. We also compared the early postoperative (on the second day after operation) nutritional status of the two groups like the levels of serum total protein, albumin and proalbumin.ResultsThe mean systolic blood pressure, mean diastolic blood pressure, mean heart rate, mean blood oxygen saturation, pain score and fasting blood glucose of the observation group at 24 hours after surgery were significantly lower than those of the control group (P<0.05), while the total serum protein, albumin and prealbumin concentrations of the observation group were significantly higher than those of the control group on the second day after surgery (P<0.05). Postoperative hospitalization time and hospitalization cost in the observation group were also shorter or less than those in the control group (P<0.05). Compared with the control group, the first postoperative anal exhaust time was earlier and the incidence of postoperative complications was reduced in the observation group, but the difference was not statistically significant (P>0.05).ConclusionsERAS combined with preoperative application of tumor total nutrition formula enteral nutrition fluid (EnsourceTM) can reduce the postoperative stress response and the postoperative complication rate of patients with rectal cancer, and also improve the postoperative nutrition status of patients and promote the rapid recovery of patients after sugery.
ObjectiveTo explore the value of geriatric nutritional risk index (GNRI) and sarcopenia on predicting postoperative complications in elderly patients with gastric cancer. MethodsAccording to the inclusion and exclusion criteria, the elderly (aged ≥60 years) patients with gastric cancer underwent radical gastrectomy in the Department of Gastrointestinal Surgery of Xuzhou Central Hospital from January 1, 2017 to December 31, 2021 were retrospectively gathered. The occurrence of postoperative complications (grade 2 or beyond by the Clavien-Dindo classification) was analyzed. The risk factors affecting postoperative complications were analyzed by univariate and multivariate logistic regression analyses to construct the prediction model, then was visualized by drawing a nomogram. The differentiation of the nomogram between the patients with postoperative complications and without postoperative complications was evaluated by the receiver operating characteristic (ROC) curve. The accuracy of the nomogram was evaluated by the calibration curve. Further, the clinical net benefit rate was analyzed by the decision curve analysis (DCA) to evaluate the clinical practicability. ResultsA total of 236 patients were gathered, 97 (41.1%) of whom had postoperative complications during hospitalization. The results of multivariate logistic regression analysis showed that the age, gender, GNRI, sarcopenia, surgical mode, and American Society of Aneshesiologists classification were the factors influencing the postoperative complications (P<0.05). The differentiation of nomogram based on the influencing factors was well, the area under the ROC curve was 0.732. The calibration curve showed that the model prediction curve was close to the ideal curve. The clinical net benefit rate by the DCA was higher when the probability of postoperative complications was 0.18 to 0.72. ConclusionsThe efficiency of nomogram based on GNRI and sarcopenia is well for predicting the occurrence of postoperative complications in elderly patients with gastric cancer. However, the nomogram needs to be further validated by prospective studies and external data.
