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 We handsearched related published and unpublished data and their references.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.
Sarcopenia is a syndrome associated with reduced strength, mass and function of skeletal muscles. Aging of gastric cancer patients, lack of nutritional intake, and pathological mechanisms of gastric cancer increase the likelihood of sarcopenia. Sarcopenia is associated with the development of gastric cancer and may be a risk factor for the formation of gastric cancer. Sarcopenia is closely related to the prognosis and treatment of gastric cancer. At present, the treatment of sarcopenia is still in the exploratory stage, and more research is needed to obtain better treatment plans and improve the quality of life of patients. This article reviews the research status of sarcopenia and gastric cancer in order to provide evidence for clinical research.
Objective To study the effect of indirect calorimetry-guided nutritional support on energy metabolism, cellular immunity and oxidative stress in patients with colorectal cancer after laparoscopic surgery. Methods A total of 96 patients with colorectal cancer after laparoscopic surgery in our hospital from December 2019 to December 2021 were selected and randomly divided into the control group (used the formula prediction method to guide enteral nutrition support, n=48) and the observation group (used indirect calorimetry to guide enteral nutrition support, n=48). The target resting energy expenditure (REE) value and nutritional support energy intake were compared between the two groups. The cellular immune indexes (CD3+, CD4+, CD8+, CD4+/CD8+) and oxidative stress indexes [serum superoxide dismutase (SOD), malondialdehyde (MDA), the changes of glutathione peroxidase (GSH-Px)], and the changes of REE at different time points (1 day before operation and 1, 2 and 3 days after operation) of the two groups were compared. The incidence of complications in the two groups were observed. Results The target REE value of the observation group was lower than that of the control group (P＜0.05), and there was no significant difference in the enteral energy intake and parenteral energy intake compared with the control group (P＞0.05). After treatment, CD3+, CD4+ and CD4+/CD8+ in the two groups were lower than those before treatment (P<0.05), and CD8+ was higher than before treatment (P<0.05). The levels of CD3+, CD4+ and CD4+/CD8+ in the observation group after treatment were higher than those in the control group (P<0.05) , while the level of CD8+ in the observation group was lower than that in the control group (P<0.05). After treatment, the levels of SOD and GSH-Px in the two groups were lower than those before treatment (P<0.05), and the levels of MDA were higher than those before treatment (P<0.05). The levels of GSH-Px and SOD in the observation group were higher than those in the control group (P<0.05), while the level of MDA in the observation group was lower than that in the control group (P<0.05). There was no significant difference in the REE value between the two groups at 1 day before operation (P>0.05); compared with the 1 day before operation, the REE values of the two groups at 1, 2, and 3 days after operation were significantly increased, and there was a statistically significant difference between the two groups at each time point (P<0.05), but the REE value at 3 days after operation was significantly lower than that at 1 and 2 days after operation (P<0.05). The REE values in the observation group were lower than those in the control group at 1, 2 and 3 days after operation (P<0.05). The incidence of complications in the observation group was 6.25%, which was lower than 20.83% in the control group (P<0.05). Conclusion Enteral nutrition support guided by indirect calorimetry in colorectal cancer patients after laparoscopic surgery can help reduce postoperative energy consumption, improve cellular immune function and oxidative stress response, and reduce the risk of postoperative complications, which is worthy of promotion.

Objective To investigate the status of nutrition, nutritional support, and postoperative nutrition-related complications in patients with spinal deformity during orthopedic perioperative period. Methods From February to August 2021, patients who underwent spinal orthopedic surgery for spinal deformity in Peking University Third Hospital were collected. A survey was conducted using self-designed questionnaire, including patient’s general information (gender, age, and type of spinal deformity), nutrition-related information (risks of malnutrition, forms of nutritional support), and postoperative nutrition-related complications. Results A total of 39 patients with spinal deformity were enrolled, and 46.2% (18 cases) were at risk of malnutrition. There were a total of 174 times of nutritional support, and 96.0% (167 times) were parenteral nutrition. The patients’ energy intake from nutritional support accounted for 34.41% of the daily goal energy intake averagely. At admission, one day after operation, and at discharge, the prealbumin was (215.51±34.69), (172.85±31.85), and (163.67±29.15) mg/L, respectively, and the hemoglobin was (138.08±15.67), (119.92±18.01), and (117.69±14.76) g/L, respectively, which were significantly lower one day after operation and at discharge than those at admission (P<0.01). The incidence of postoperative nutrition-related complications during hospitalization was 5.1% (2/39). Conclusions Patients undergoing spinal deformity orthopedics are at high risk of overall malnutrition during the perioperative period, their clinical nutritional interventions are mostly based on parenteral nutrition with a single infusion of nutritional preparations, and the nutritional status is not significantly improved. However, the incidence of postoperative nutrition-related complications is low. Standardized nutrition interventions should be strengthened in the future.
ObjectiveTo introduce the progresses and applications of nutritional status assessment in hospitalized patients. MethodsThe related literatures of nutritional status assessment were reviewed. ResultsThe rates of malnutrition and nutritional risk were high in hospitalized patients worldwide. Traditional nutrition assessment tools were not in common use in all hospitalized patients. All clinical health care workers should use the most suitable tool when faced with different patients. ConclusionAll hospitalized patients should be screened for nutritional risk on admission in order to improve clinical outcomes and reduce overall treatment costs.
ObjectiveTo explore the role of nutritional support in adjuvant therapy for respiratory failure. MethodsWe took 72 patients with respiratory failure who were treated in our hospital from August 2011 to January 2013 as the research objects. They were divided into two groups:control group and trial group, with 36 patients in each group. The division of the groups was in accordance with the state food and drug administration clinical trial institution ethics committee standard operating procedures. In the control group, 36 patients were provided with regular treatments according to their condition, like maintaining the respiratory tract unobstructed, oxygen therapy, mechanical ventilation and anti-infection. In the trial group, we offered nutritional support in addition to the normal treatment. Consecutive 20 days was a course of treatment. After four courses, we inspected and put down two groups' respective clinical features, and made a contrast of their treatment conditions. We analyzed the treatments through observational indexes including assessment of eutrophication, treatment efficiency, pulmonary function and arterial blood gases. ResultsBoth groups had obvious therapeutic effects. The observational indexes in the trial group were better than those in the control group. The total effective rate was 91.7% in the trail group after treatment, significantly higher than that in the control group (66.7%) (χ2=8.692, P=0.003); the lung capacity, the ventilation flow ratio and arterial blood gas analysis values in the trial group was better than those in the control group. ConclusionThe effect of the nutritional support for the respiratory failure treatment is much better than the regular treatment. The total effective rate is improved while the death rate is lower than before and the patients recover quickly.
Objective To compare the clinical effects of early enteral and parenteral nutrition, and to study their effects on cytokine release, cellular immune function and protein metabolism in early postoperative patients with gastrointestinal cancer. Methods Thirty-six patients with gastrointestinal cancer were randomly divided into early postoperative enteral nutrition (EN) group (19 cases) and parenteral nutrition (PN) group (17 cases), and they were supported with EN or PN during postoperative period of 1-7 days, respectively. The levels of serum tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), and interleukin-10 (IL-10) were measured by ELISA. The total lymphocyte count (TLC) and subgroups of lymphocyte (CD3, CD4, CD8, CD4/CD8 and NK cell) were determined with flow cytometer. The urea and creatinine of the 24 h excretory urine were examined at four different phases: preoperative (pre), 1st d, 3rd d and 5th d after operation (pod). The clinical recovery indicators and the complication incidence were also observed. Results All the patients followed the project of nutritional support and relevant examinations, and there was no severe complication and no patient died during the research. The IL-1β, IL-6 and IL-10, the 24 h urea and creatinine increased, while the serum TNF-α and TLC (except 3, 5 pod of EN group) decreased. There was no marked change of the proportion of lymphocyte subgroups after operation and there was no significant difference of the changes of IL-1β, IL-10 and TNF-α between the two groups as well. The levels of IL-6 (3, 5 pod), the 24 h urea (3, 5 pod) and creatinine (3, 5 pod) were significantly lower in EN group than those in PN group （P＜0.05）, whereas TLC (3, 5 pod) were significantly higher than that in EN group （P＜0.05）. In addition, the postoperative infection incidence （10.5% vs 35.3%）, fever duaration, rehabilitation time and medical cost were significantly lower in EN group than those in PN group （P＜0.05）.Conclusion The early postoperative EN has an advantage over PN in the patients with gastrointestinal cancer, which could decrease the release of cytokine and suppress protein metabolism resulting from operational stress, and could reduce the incidence of postoperative infection and inflammatory reaction time. They could also improve the cellular immune function and decrease the rebilitation duration and medical cost.
