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 explore the effect of early enteral nutrition in the clinical treatment of severe acute pancreatitis (SAP). Methods Forty-two SAP patients who improved with non-surgical treatments between January 2012 and December 2014 were selected and randomly divided into control group and study group with 21 patients in each. Patients in the control group accepted whole venous nutrition, while those in the study group had early enteral nutrition. Nutrition indexes, blood biological indexes, and Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ score on day 7 and 14 after treatment, and average hospital stay of the two groups of patients were recorded and compared. Results No differences in body weight reduction, lymphocytes, serum albumin, calcium, glucose, APACHE Ⅱ score between the two groups after 7 days of treatment were observed (P>0.05). But there were significant differences in body weight, lymphocytes, serum albumin, and APACHE Ⅱ score between these two groups after 14 days of treatment (P<0.05). Hospital stay of the study group was obviously shorter (P<0.01). Conclusions Early enteral nutrition support for patients with severe acute pancreatitis can improve nutritional status and shorten hospital stay. It is worthy of wider clinical application.
Chronic kidney disease (CKD) is a public health issue of global concern, and nutritional management of CKD can improve the nutritional status of patients and slow down the progression of the disease. However, nutrition management is a complex scientific issue, and there are few clinical practices of nutrition management in CKD, so there is an urgent need for a theoretical framework of nutrition management to guide the construction of a scientific and standardized program. This review will systematically describe the relationship between nutrition and kidney disease, sort out the current status of nutrition management in CKD in China, introduce the experience of CKD medical and nursing nutrition integration in West China Hospital of Sichuan University, and provide thoughts for further improvement of standardized scientific formulation of nutrition management strategy.
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.
ObjectiveTo investigate the influence of enteral nutrition (EN) and total parenteral nutrition (TPN) on liver, kidney and gastrointestinal function in patients after esophagectomy. MethodsA total of 124 patients with esophageal cancer who underwent esophagectomy in the Affiliated Hospital of Guangdong Medical College from January 2012 to August 2013 were enrolled in this study. There were 71 male and 53 female patients with their average age of 59.7 years (range 31 to 85 years). All the patients were randomly divided into an experimental group and a control group. Postoperatively, patients in the experimental group received EN via nasogastric/nasointestinal tube, and patients in the control group received TPN. Preoperatively, 1, 3 and 7 days postoperatively, plasma alanine transaminase (ALT), aspartate transaminase (AST), indirect bilirubin (I_BIL), direct bilirubin (DB), total bilirubin (TB), total protein (TP) and albumin (ALB) were examined to evaluate liver function, blood urea nitrogen (BUN) and serum creatinine (Scr) were examined to evaluate renal function. Postoperative time to first audible bowel sounds, time to first flatus, and time to first stool were examined to evaluate gastrointestinal function. ResultsThere was no statistical difference in ALT, AST, I_BIL, DB or TB preoperatively and on the 1st postoperative day between the 2 groups (P > 0.05), but these parameters of the experimental group were significantly lower than those of the control group on the 3rd and 7th postoperative day (P < 0.05). There was no statistical difference in TP or ALB between the 2 groups (P > 0.05). There was no statistical difference in BUN or Scr preoperatively, on the 1st or 3rd postoperative day between the 2 groups (P > 0.05). BUN (4.94±1.07 mmol/L vs. 6.67± 2.88 mmol/L, P < 0.05) and Scr (52.50±12.46 μmol/L vs. 68.23±7.61 μmol/L, P < 0.05) of the experimental group were significantly lower than those of the control group on the 7th postoperative day. Postoperative time to first audible bowel sounds (42.00±1.68 hours vs. 50.00±1.54 hours), time to first flatus (64.15±10.35 hours vs. 70.64±14.73 hours) and time to first stool (4.20±1.50 days vs. 5.20 ±1.40 days) of the experimental group were significantly shorter than those of the control group (P < 0.05). ConclusionPostoperative EN can promote the recovery of gastrointestinal function, and has less influence on liver and kidney function, which is beneficial to postoperative recovery and morbidity reduction after esophagectomy.
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.
ObjectiveTo investigate the prevalence of the nutritional risks, the relationship between application of nutritional support and the clinical outcome of patients with gastrointestinal major surgery in the Frist People's Hospital of Shuangliu. MethodsGastrointestinal major surgery patients in Department of General Surgery in the Frist People's Hospital of Shuangliu from March 2010 to March 2014 were consecutively enrolled. Patients who provided informed consent were screened by NRS 2002, tracking nutrition support status and analysis the relationship between nutrition support and clinical outcome. In this study, the clinical outcome index included postoperative complications and hospitalization time. ResultsThere were totally 130 cases enrolled, 112 cases completed assessment by NRS 2002. The prevalence of nutritional risk was 75.9%(85/112), there were totally 57 patients(50.9%) received nutrition support, and all for parenteral nutrition. The prevalence of postoperative complication was 46.4%(52/112). The prevalence of postoperative complication in patients who had nutritional risk and received nutritional support was 41.7%(15/36), whereas, in patients who had nutritional risk but not received nutritional support was 73.5%(36/49), there was statistically significant difference between the 2 groups(P=0.002). In patients who not had nutritional risk, the postoperative complication rate was only 3.7%(1/27). ConclusionsBecause of noninvasive and easy to operate, NRS 2002 are adpted to hospitalized patients with gastrointestinal major surgery. Because of the specific of disease metabolism, the higher nutritional risk occurres in patients with gastrointestinal major surgery, appropriate nutritional support for this kinds of patients can reduce the incidence of postoperative complication, and improve the prognosis.
Objective To investigatethe anatomic structure of the compound flap of distally-based saphenous nervegreat saphenous vein nutritional vessels so as to provide anatomic basis for the clinical operation. Methods The origin, branches, anastomosis of nutritional vessels of sural nerve-great saphenous vein, and the relationof blood supply of tibia and soleus muscle were observed on 30 low limb specimens of adult cadaver, which were perfused with red gelatin to dissect from the artery. Results The nutritional vessels of sural nerve-great saphenous vein originated from: the saphenous artery 3-5 branches with a diameter of 0.7±0.4 mm；the cutaneous branches of medial inferior genicular artery, diameter of 0.7±0.2 mm；the intermuscular space perforating branches of posterior tibial artery 2-7 branches with a diameter of 1.0±0.2 mm，the internus halfside of the muscular branches nutrient soleus muscle；the perforating osteoseptocutaneous 1-2 branches with a diameter of 1.3±0.3 mm; the perforating branches of superior malleolus with a diameter of 0.6±0.2 mm; the perforating branches of medial anterior malleolus with a diameter of 0.8±0.3 mm. A vascularnetwork of 3 layers, which included periosteum, deep artery, and fascia nerve and superficial vein, was formed by those branches of deep artery, fascia branches, periosteum branches, and nerve-vein nutrition branches. Conclusion The nutritional vessels of saphenous nerve-great saphenous vein has the same origin as muscles, bones, and cutaneous nutritional vessels. It provides anatomic basis for the compound flap of distally-based saphenous nerve nutritional vessels.
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.
