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 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.
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.
Objective To investigate the role of rehabilitation therapy both on nutritional status and intestinal adaptation of patients with short bowel syndrome (SBS). Methods The literatures about rehabilitation therapy for SBS were reviewed. Results Intestinal rehabilitation refers to the process of restoring enteral autonomy, in order to get rid of parenteral nutrition, usually by means of dietary, medical, and surgical treatment. Recent researches showed that medication and the use of specific nutrients and growth factors could stimulate intestinal absorption and might be useful in the medical management of SBS. Conclusion Intestinal rehabilitation is of benefit in the treatment of SBS and would play a greater role in the future.
Objective To assess the effect and safety of clinical nutritional supplementation with different patterns for treating systematic inflammatory response syndrome (SIRS). Methods Randomized controlled trials (RCTs) were identified from MEDLINE (1996 to Nov. 2004), EMBASE (1984 to Nov. 2002), Cochrane Controlled Trials Register (Issue 4, 2004), Chinese Cochrane Centre Database (Issue 4, 2004), CBMdisc (1978 to Nov. 2004). We handsearched related published and unpublished data and their references. All RCTs of nutritional interventions for SIRS were included. Data were extracted and evaluated by two reviewers independently with designed extraction form. RevMan 4.2.7 software was used for data analysis. Results Six RCTs involving 353 patients were included. All the results of meta-analysis were listed as the following: ① Mortality: compared with routine nutrition, one study showed that glutamine had a statistical difference with RR 0.67 and 95%CI 0.31 to 1.32. Compared with no treatment, one study showed selenium had a statistical difference with RR 1.19, 95%CI 0.59 to 2.41. ② Compared with routine nutrition, one study showed that glutamine had a statistical difference on reducing the ratio of nasocomial infection of SIRS with RR 0.5, 95%CI 0.27 to 0.91, but had no statistical difference on reducing the ratio of multiple organ dysfunction syndrome with RR 1.53, 95%CI 0.64 to 3.66. ③ Improvement of the critical condition of SIRS: compared with routine nutrition, one study showed that glutamine had a statistical differences with WMD 4.0, 95%CI 2.36 to 5.64; compared with high calorie intake, two studies showed low calorie intake had a statistical difference with WMD 4.9, 95%CI 1.76 to 8.04. ④ Reduction of the complication of hyperglycemia and hypertriglyceridemia: compared with high calorie intake, one study showed low calorie intake had statistical difference with WMD －0.70, 95%CI －1.20 to －0.20 and WMD －1.80, 95% CI －2.42 to －1.16 respectively and all P≤0.01. ⑤ Increasing of the plasma IgG concentration: compared with routine nutrition, two studies showed that glutamine had a statistical difference with WMD 4.20, 95% CI 2.23 to 6.16. ⑥ Increasing of the nitrogen balance, intestinal permeability, the level of plasma concentration of anlbumin, prealbumin and TRF: compared with control interventions, glutamine, low calorie intake, selenium supplementation and fructose-glucose-xylitol mixture showed no statistical difference. Conclusions Glutamine, low calorie intake, selenium supplementation, FGX mixture may decrease the complication of infection or metabolism and be better than the controlled interventions; but there is no benefit on reducing the rate of death result from SIRS compared with controlled interventions. The evidence of most RCTs with poor quality is too weak to draw a conclusion. More high quality trials are required.

Objective To investigate the impact of nutritional risk on unplanned readmissions in elderly patients with chronic obstructive pulmonary disease (COPD), to provide evidence for clinical nutrition support intervention. Methods Elderly patients with COPD meeting the inclusive criteria and admitted between June 2014 and May 2015 were recruited and investigated with nutritional risk screening 2002 (NRS 2002) and unplanned readmission scale. Meanwhile, the patients’ body height and body weight were measured for calculating body mass index (BMI). Results The average score of nutritional risk screening of the elderly COPD patients was 4.65±1.33. There were 456 (40.07%) patients who had no nutritional risk and 682 (59.93%) patients who had nutritional risk. There were 47 (4.13%) patients with unplanned readmissions within 15 days, 155 (13.62%) patients within 30 days, 265 (23.28%) patients within 60 days, 336 (29.53%) patients within 180 days, and 705 (61.95%) patients within one year. The patients with nutritional risk had significantly higher possibilities of unplanned readmissions within 60 days, 180 days and one year than the patients with no nutritional risk (all P<0.05). The nutritional risk, age and severity of disease influenced unplanned readmissions of the elderly patients with COPD (all P<0.05). Conclusions There is a close correlation between nutritional risk and unplanned readmissions in elderly patients with COPD. Doctors and nurses should take some measures to reduce the nutritional risk so as to decrease the unplanned readmissions to some degree.
Objective To investigate the effect of FLEEOX regiment on nutritional status of advanced gastric cancer patients after neoadjuvant chemotherapy. Methods Forty-eight cases of advanced gastric cancer patients from December 2010 to October 2011 in this hospital were included into. The indexes of body composition and the blood related nutritional indicators before and after neoadjuvant chemotherapy were determined. Results After neoadjuvant chemotherapy，the body weight，intracellular fluid，body mass index，protein，body fat，body cell mass，and arm circumference mildly decreased；extracellular fluid，body water content，inorganic salts，bone mineral content，non-fat group，skeletal muscle，and arm muscle circumference mildly increased，but the differences were not statistically significant （P＞0.05）. The blood albumin，prealbumin，total protein，transferrin，and lymphocytes decreased at different degrees down，but the differences were not statistically significant （P＞0.05）. Conclusion Patients have no obvious changes in nutritional status during chemotherapy of FLEEOX regiment.
ObjectiveTo explore the nutritional status of inpatients with chronic kidney disease (CKD) and analyze the factors affecting nutritional risk, to provide theoretical basis for further nutritional support.MethodsConvenience sampling method was adopted to select 719 inpatients with CKD as research subjects in a tertiary hospital in Chengdu, Sichuan Province from January to March 2018. Nutritional Risk Screening 2002 was used for nutritional risk screening, and chi-square test, t test, one-way analysis of variance, and multiple linear regression analysis were used to explore the influencing factors of nutritional risk.ResultsAmong the 719 cases, whose average nutritional risk score was 1.79±1.11, 158 cases had nutritional risk, accounting for 22.0%. There were statistically significant differences in nutritional risk score between patients of age<60 years and ≥60 years, between males and females, between patients with CKD stage 1-3 and stage 4-5, between patients with serum albumin level <30 g/L and ≥30 g/L, and between patients with and without anaemia (P<0.05). The results of multiple linear regression analysis showed that the nutritional risk score of CKD patients was negatively correlated to serum albumin level (P=0.016), positively correlated to age (P<0.001), and higher in females than that in males (P=0.001).ConclusionsInpatients with CKD have a higher nutritional risk, with age, gender and serum albumin as the main influencing factors. Based on the above factors, the medical staff should continue to take targeted intervention measures to assess the nutritional status of CKD inpatients early and conveniently, so as to provide scientific basis for further nutritional support and nutritional nursing.
ObjectiveTo explore the effect of perioperative nutritional management on patients with spinal cord injury under the enhanced recovery after surgery (ERAS) theory.MethodsA total of 82 patients with spinal cord injury admitted to a tertiay hospital in Shanghai between August 2018 and May 2020 were selected by convenience sampling method. They were randomly divided into intervention group and control group, with 41 cases in each group. The patients in the control group received conventional orthopaedics elective surgery nutritional management, while the patients in the intervention group adopted perioperative nutritional management based on ERAS concept, including establishing a multidisciplinary nutritional management team, conducting admission and regular nutritional screenings, and then developing targeted nutritional interventions based on the screening results. Biochemical indexes of nutritional assessment, electrolyte indexes, nutrition-related complications and general inpatient indexes were observed and compared between the two groups.ResultsThere were statistically significant differences in albumin, prealbumin, total protein, hemoglobin, potassium, sodium, and chlorine between the two groups on the first day after surgery and one day before discharge (P<0.05). The incidences of hypoglycemia (2.4% vs. 19.5%) and total complications (19.5% vs. 61.0%) in the intervention group were lower than those in the control group, and the differences were statistically significant (P<0.05). The total hospital stay [(10.48±2.61) vs. (12.09±2.74) d], postoperative hospital stay [(5.57±2.35) vs. (7.55±3.01) d], and hospital expenses [(11.21±4.42)×104 vs. (14.73±5.51)×104 yuan] in the intervention group were less than those in the control group (P<0.01).ConclusionPerioperative nutritional management under the ERAS theory can effectively improve the nutritional status of patients with spinal cord injury, maintain electrolyte balance, reduce the incidence of complications, shorten the length of hospitalization, reduce the cost of hospitalization, and promote postoperative rehabilitation of patients.
