In the context of accelerated rehabilitation, nutritional support for patients with orthopedic cervical spondylosis is an important condition for lessening postoperative stress response, reducing postoperative complications, shortening patient’s length of hospital stay, lowering medical expenses, and promoting early recovery of patients. Based on this, West China Hospital of Sichuan University explored and established the West China Hospital program for nutritional management in cervical spondylosis from the aspects of team building, nutritional assessment and monitoring, and nutritional intervention.
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 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.
One of the most difficult problems on tendon surgery is adhesion formation during the process of tendon healing, which causes functional interference. This pathophysiologic pcocess is closely related to the ways of tendon nourishment and types of tendon healing. In order to understand whether the sutured tendon couldheal without blood circulation, the process and types of tendon healing in the synovial fluid were studied by in vivo culture modle. Flexor digitorum profundus (FDP) segments from the front paw of 50 New Zedland white rabbits were cut inthe middle and sutured with microsurgical technique, and then, preserved in thesynovial cavitied of both knees of the rabbits. After 1, 2, 4, 6 weeks, the specimens from the synovial cavities were studied by gross observation, light microscope, scanning and transmission electron microscope, and biochemical determination. The results showed that the tendon which was nourished by synovial fluid not only could survive, but also could heal. Healing of the tendon was completed by activation and proliferation of both peritendon cells and cells in the tendon.The healing could be devided into 3 periods: malnutrition period (less than 1 week), reparative period (2-4 week) and rebuilding period (more than 4 week).
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 observe the effects of levocarnitine by intravenous injection on nutritional and microinflammatory state in maintenance hemodialysis patients.
MethodsBetween October 2010 and October 2011, 62 maintenance hemodialysis (>6 months) patients in our dialysis center were enrolled in this study, and were randomly divided into treatment group (n=32) and control group (n=30). Patients in the treatment group were injected with levocarnitine (1.0 g once) after every dialysis for 3 months, while patients in the control group only accepted routine hemodialysis therapy. Blood biochemical indicators, serum high sensitive C-reactive protein (hs-CRP) were measured and compared at the experiment onset and 3 months later.
ResultsAfter treatment with levocarnitine for three months, the average serum levels of albumin (Alb), hemoglobin (Hb), triacylglycerol (TG), high density lipoprotein cholesterol (HDL-C) and hs-CRP, and the conditions of dialysis hypotension, muscular spasm, lacking in strength, and anorexia were significantly different between the two groups (P<0.05). But there was no significant difference in total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) between the two groups (P>0.05). For the control group, after treatment, Alb, Hb and condition of anorexia changed significantly (P<0.05), while TC, TG, LDL-C, HDL-C, hs-CRP, conditions of dialysis hypotension, muscular spasm and lacking of strength did not change (P>0.05); for the treatment group, after treatment, all Alb, Hb, TG, HDL-C, hs-CRP, conditions of dialysis hypotension, muscular spasm, lacking of strength and anorexia changed significantly (P<0.05), while TC and LDL-C did not change obviously (P>0.05).
ConclusionLevocarnitine can significantly improve the nutritional and microinflammatory state and better the quality of life in maintenance hemodialysis 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.
