This study was disigned to determine the effect of nutritional status on the energy metabolism of liver. Rat liver of four nutritional groups (Group Ⅰ： fasting; Group Ⅱ: surgar feeding diet; Group Ⅲ: normal feeding diet; Group Ⅳ: group Ⅰ and group Ⅱ accepted patenteral nutrition) were removed for study. The adenosine triphosphate (ATP) level, total addenosine nucleotides (TAN) level, and adenylaty energy charge (EC) of liver decreased in group Ⅰ and group Ⅱ in contrasted with group Ⅲ (Plt;0.001), result of group Ⅳ was similar to that of group Ⅲ when the liver specimens were collected. The rusults indicate that a short period of starvation and low sugar intake will result in the malnutrition of liver and derangement of hapatic energy metabolism and material metabolism. But this status can be corrected by a short perios of parenteral nutrition.
Objective To investigate the distribution of the perforating branches artery of distally-based flap of sural nerve nutrient vessels and its clinical application. Methods The origins and distribution of perforating branchesartery of distally-based flap were observed on specimens of 30 adult cadavericlow limbs by perfusing red gelatin to dissect the artery.Among the 36 cases, there were 21 males, 15 females. Their ages ranged from 6 to 66, 35.2 in average. The defect area was 3.5 cm×2.5 cm to 17.0 cm×11.0 cm. The flap taken ranged from 4 cm×3 cm to 18 cm×12 cm. Results The perforating branches artery of distally-based flap had 2 to 5 branches and originated from the heel lateral artery, the terminal perforating branches of peroneal artery(diameters were 0.6±0.2 mm and 0.8±0.2 mm, 1.0±1.3 cm and 2.8±1.0 cm to the level of cusp lateral malleolus cusp).The intermuscular septum perforating branches of peroneal artery had 0 to 3 branches. Their rate of presence was 96.7%,66.7% and 20.0% respectively(the diameters were 0.9±0.3, 1.0±0.2 and 0.8±0.4 mm, andtheir distances to the level of cusp of lateral malleolus were 5.3±2.1, 6.8±2.8 and 7.0±4.0 cm). Those perforating branches included fascia branches, cutaneous branches, nerve and vein nutrient branches. Those nutrient vessels formed longitudinal vessel chain of sural nerve shaft, vessel chain of vein side and vessel network of deep superficial fascia. The distally-based superficial sural artery island flap was used in 18 cases, all flaps survived. Conclusion Distally-based sural nerve, small saphenous vein, and nutrient vessels of fascia skin have the same origin. Rotation point of flap is 3.0 cm to the cusp of lateral malleolus, when the distally-based flap is pedicled with the terminal branch of peroneal artery.Rotation point of flap is close to the cusp of lateral malleolus, when the distally-based flap is pedicled with the heel lateral artery.
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.
Lung cancer ranks among the most prevalent and lethal malignancies globally. Its prognostic outcomes are not only contingent upon tumor characteristics and therapeutic interventions but also intricately linked to the nutritional and immune profiles of patients. This article conducts a thorough review of both domestic and international research, providing a comprehensive synthesis of the prognostic value of widely investigated nutritional and immune indicators in the context of lung cancer. The primary objective is to identify optimal prognostic markers in clinical practice, offering guidance for precise post-treatment assessment and early intervention for lung cancer patients.
Objective To investigate the effect of early postoperative enteral nutrition support on the balance of free amino acid spectrum in plasma for patients with cardiac valve replacement during perioperative period. Methods (Forty-seven) patients undergoing cardiac valve replacement were divided into two groups randomly, the routine diet group and the Nutrison Fibre group. The levels of free amino acids in plasma were measured with pre-column derivatization of high-performance liquid chromatography. Results During perioperative period most free amino acids in plasma decreased significantly in the routine diet group (Plt;0.05). Despite some free amino acids in plasma decreased significantly in the Nutrison Fibre group(Plt;0.05), all free amino acids in plasma returned to (Pgt;05) or were higher than the preoperative levels in the postoperative sixth day (Plt;0.05). At the same postoperative points, most free amino acids in plasma in the Nutrison Fibre group were higher than that of the routine diet group (Plt;0.05). Conclusions The levels of free amino acids in plasma decrease significantly in patients with cardiac valve replacement after operation. Early postoperative Nutrison Fibre enteral nutrition support is helpful for keeping the balance of free amino acids in plasma for patients with cardiac valve replacement.
Schwanns cell (SC) was isolated from sciatic nerve of adult rat with Wallerine degeneration. After culture, SC-serum free culture media (SCSFCM) was obtained. By ultrafiltration with PM-10 Amicon Membrane, electrophoresis with DiscPAGE,and electrical wash-out with Biotrap apparatus, D-band protein was isolated from the SC-SFCM. The D-band protein in the concentration of 25ng/ml could affect the survival of the spinal anterior horn neuron in vitro, prominently and itsactivity was not changed after being frozen. The molecular weight of the protein ranged from 43 to 67 Kd. The D-band protein might be a neurotrophic substancedifferent from the known SCderived neurotrophic factors (NTF). Its concentration with biological activity was high enough to be detected. The advantages of MTT in assessment of NTF activity were also discussed.
Objective To study effects of enteral immunonutrition and econutrition on intestinal mucosa barrier function in wounded rats. Methods Forty Wistar rats were randomly divided into four groups, with ten rats in each group 〔ie.control group, enteral nutrition (EN) group, enteral immunonutrition (EIN) group and enteral econutrition (EEN) group〕. After gastrostomy, rats in each group were treated with the isocaloric and isonitrogenous nutritional formulas for 7 days, respectively. The morphology of ileum membrane was studied, and the quantities of IgA+, CD3+, CD4+ and CD8+ cells (each HP) of ileum membrane were determined. Results The villus height, crypt depth, mucosal thickness (except EN group) and villus surface area of ileum were increased in EN, EIN and EEN group compared with control group (P＜0.05), but there was no significant difference among the former three groups (Pgt;0.05). The numbers of IgA+, CD3+, CD4+ and CD8+ cells were increased in EN, EIN and EEN group compared with control group (P＜0.05), and those numbers in EN group were lower than those in EIN and EEN group (P＜0.05). Conclusion EIN and EEN may improve intestine mechanical barrier function and promote restoration of small intestine mucous membrane barrier function in rats. EIN and EEN also improve intestine immune barrier function and strengthen its immune function.
Objective To assess the prevalence of malnutrition in patients with advanced non-small cell lung cancer (NSCLC) using the Global Leadership Initiative on Malnutrition (GLIM) criteria, analyze its associated factors, and explore the adverse effects of malnutrition on advanced NSCLC patients in multiple aspects. Methods Patients with NSCLC who were hospitalized for the first time in the Department of Oncology, Shangjin Hospital, West China Hospital, Sichuan University between January and December 2021 were retrospectively selected as the study objects. Malnutrition assessment was carried out in all patients according to GLIM criteria, and the current situation and related factors of malnutrition were analyzed. The Barthel index scale was used to compare the daily activity ability between the malnourished group and the non-malnourished group, the Quality-of-Life Questionnaire-Core 30 scale was used to compare the quality of life between the two groups, and the adverse reactions of the two groups were compared by the hospital information system course records. Results According to GLIM diagnostic criteria, 134 of 285 patients (47.0%) were diagnosed with malnutrition. The results of binary multiple logistic regression analysis showed that age [60-69 vs. <60 years old: odds ratio (OR)=2.323, 95% confidence interval (CI) (1.277, 4.397); ≥70 vs. <60 years old: OR=10.816, 95%CI (4.185, 27.959)], previous medical history [OR=2.740, 95%CI (1.313, 5.717)], and albumin level [OR=0.905, 95%CI (0.848, 0.965)] were associated with malnutrition in patients with advanced NSCLC (P<0.05). The daily activity ability and quality of life in the malnourished group were significantly worse than those in the non-malnourished group (87.57±12.48 vs. 91.82±6.77, P<0.05; 76.22±11.52 vs. 83.96±9.75, P<0.05), and the incidence of adverse reactions in the malnourished group was higher than that of the non-malnourished group (50.7% vs. 31.8%, P<0.05). Conclusions The prevalence of malnutrition in patients with advanced NSCLC is high, and advanced age, previous medical history and albumin are related factors of malnutrition in patients with advanced NSCLC. Combined malnutrition may have adverse effects on mobility, quality of life and adverse effects of anti-tumor therapy in advanced NSCLC patients.
ObjectiveTo compare the outcome between two nutrition support methods, total enteral nutrition (TEN) and enteral nutrition combined with parenteral nutrition, in infants after ventricular septal defect (VSD) repair operation. MethodsWe retrospectively analyzed the clinical data of 76 infants who underwent VSD repair operation in Xinhua Hospital in 2012 year. There were 46 males and 35 females aged 1.6-11.9 (5.5±2.5) months. Nutrition support was started from the first day after operation. There were 35 patients in the group A with TEN 60 kcal/(kg·d), and 41 patients in the group B with both enteral nutrition at 30 kcal/(kg·d) and parenteral nutrition at 30 kcal/(kg·d). ResultsThere was no statistical difference between two groups in demography data and preoperative clinical indicators. The number of patients suffered abdominal distension and gastric retention was more in the group A (22.9% vs. 4.9%, 68.6% vs. 2.4%, P<0.05). There was no difference in diarrhea. The completion of nutrition support in the group A was worse than that in the group B. In the group A, only 40% of the goal calorie was finished on the first and the second day after operation. It was improved until the third day, and the goal calorie could be finished on the seventh day. In the group B, the nutrition support method could be finished on the first day. The prealbumin level in the group B was significantly higher on the third, fifth and seventh day (P<0.05). The blood urea nitrogen (BUN) level in the two groups on the first day after operation was higher than that before operation (P<0.05), and persisted in the group A, while decreased to the normal level gradually in the group B. Following up to discharge, the weight was higher and the length of stay was shorter in the group B (P<0.05). There was no statistical difference in the cost of hospitalization between the two groups (P>0.05). ConclusionThe nutrition support method, enteral nutrition combined with parenteral nutrition, is better than TEN for infants after VSD repair operation.
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.
