Objective To study the effects and mechanisms of major immune nutrients and to introduce the progresses of clinical applications about enteral immunonutrition. Methods The related literatures about the effects and clinical applications of enteral immunonutrition were reviewed. Results Infection rate can be reduced and the hospitalization can be shortened as a result of the improved nutritional status and immune competence of patients which can be enhanced by reasonable enteral immune nutrition. Most of the patients suffering from serious diseases can benefit from enteral immunonutrition, such as gastrointestinal cancers, post-transplantation complications, chronic liver disorders, acute pancreatitis and so on. However, as a new nutrition therapy, the clinical use of enteral immunonutrition in critically ill patients is still controversial. Conclusions Enteral immunonutrition plays an important role in the nutritional support of patients with serious diseases, such as gastrointestinal cancers, organ failures. However, much work remains to be done.
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.
Objective To promote the clinical application of parenteral and enteral nutrition preparations in hospitalized patients. Methods Domestic and foreign articles about parenteral and enteral nutrition support were enrolled to make a review. Results Nowadays, parenteral and enteral nutrition played an important role in the medical treatment of perioperative and critically ill patients. Rational nutrition support could improve the condition of patients with nutritional risk and result in better clinical outcomes. Different enteral nutrition formulations should be used according to the diseases. Supplementally parenteral nutrition may also be useful in combination with enteral nutrition to reach the required intake targets. We should pay attention to the application of glucose, lipid emulsion, amino acids, vitamins, and so on, when performed parenteral nutrition support. Conclusion It is necessary to standardize parenteral and enteral nutrition support in the work of clinical practice, including the application of nutrition support and selection of nutrition preparations.
Objective To investigate the influence of different mechanical ventilation modes on inflammatory reaction among COPD patients with severe respiratory failure. Methods A total of 102 COPD patients with severe respiratory failure, admitted in Zhongshan Hospital between January 20007 and June 2012, were enrolled in this study. The subjects were divided into an ASV group receiving adaptive support ventilation, and a SIMV + PSV group received synchronized intermittent mandatory ventilation and pressure support ventilation, with 51 cases in each group. Breathing pattern, respiratory mechanics, hemodynamic parameters and seruminflammatory factors were examined among all patients. Results Tidal volume ( VT ) was significantly higher, and the control respiratory rate and ventilation time were significantly lower in the ASV group than those in the SIMV + PSV group ( P lt; 0.05) . Comparing with the SIMV + PSV group, obviously lower peak airway pressure ( Ppeak) ,mean airway pressure ( Pmean) and airway plateau pressure ( Pplat) were observed in the ASV group ( P lt; 0.05) . The patients in the ASV group had obviously lower levels of C-reactive protein, procalcitonin and α1 acid glycoprotein. Conclusion ASV ventilation mode may reduce the inflammatory reaction, facilitate spontaneously breathing and decrease mechanical ventilation time.
Objective To evaluate the results of thumb opposition function by transferring the extensor carpi ulnaris and the extensor poll icis brevis muscle tendons. Methods Between March 2006 and August 2009, 35 patients with dysfunction of thumb opposition were treated and the thumb opposition function was reconstruced by transferring the extensor carpi ulnaris and the extensor poll icis brevis muscle tendons. There were 25 males and 10 females with an average age of 33.5 years (range, 20-53 years); 20 had median nerve injury in the wrist and 15 had median nerve injury with ulnar nerve injury. The causes were sharp instrument injury in 24 cases, blunt injury in 9 cases, and hot crush injury in 2 cases. Six cases complicated by shaft fractures of radius and ulna. All the patients underwent an operation of nerve repair at 1 to 3 hours after injury (mean, 2 hours). The time from injury to reconstructing operation was 6-14 months (mean, 7.5 months). Two cases was able to abduct thumb sl ightly, the others had no functions of thumb abduct and thumb opposition. Results All the wounds gained the primary healing. The patients were followed up 12-18 months (mean, 14 months). The wrist joint angle and thumb dorsal extension were satisfactory. Thumb abduct and thumb opposition function returned to normal in 20 patients with simple median nerve injury; in 15 patients with median nerve injury and ulnar nerve injury, thumb abduct and thumb opposition function returned to normal in 15 and 13, respectively. According to ZHAO Shuqiang’s standard, the results of thumb opposition function were normal in all patients at 12 months after operation. Conclusion It is a convenient and efficient procedure to reconstruct thumb opposition function by transferring the extensor carpi ulnaris and the extensor poll icis brevis muscle tendons.

ObjectiveTo investigate the nutritional risk, incidence of malnutrition, and clinical application of nutrition support in hospitalized patients with gastric cancer by the nutritional risk screening (NRS) 2002 score summary table. MethodsFrom June 2009 to February 2010, nutritional risk screen and application of clinical nutritional support were carried out in the hospitalized patients with gastric cancer in this hospital. Nutritional risk was assessed case-by-case according to the severity of illness, nutritional status 〔including body mass index (BMI), recent changes in body weight and eating〕 and patients age. NRS ≥3 was accepted as nutritionally at-risk, while NRS lt;3 no nutritional risk; BMI lt;18.5 kg/m2 (or albumin lt;30 g/L) combined with clinical conditions was judged to be malnourished. Results Three hundreds and eighty-six patients were included, 329 of which completed the NRS2002 screening. One hundred and sixty-five patients (50.15%) were at nutritional risk, while another 164 (49.85%) were no nutritional risk. Malnutrition was found in 57 patients (17.33%). By gender, male malnourished patients and nutritionally at-risk patients were accounting for 16.45% (38/231) and 48.05% (111/231) respectively, while female nutritionally at-risk patients and malnourished patients were accounting for 55.1% (54/98) and 19.39% (19/98) respectively, 72.04% (237/329) of the screened patients accepted clinical nutrition support, among which, 115 patients were at nutritional risk, accounting for 69.70% in that group, and 122 patients were no nutritional risk, accounting for 74.39% in that group. ConclusionsThe incidences of malnutrition and nutritionally at-risk in hospitalized gastric cancer patients are high. And irrationality of clinical nutrition support exists. Evidence-based guidelines are required to improve the nutritional status of support.
Objective To explore the postoperative influence of intra-abdominal implantation of sustained-releasing 5fluorouracil on the hepato-renal function, immune function, nutritional state and complications in patients with gastric and colorectal cancer. Methods Sixty-five patients with gastric or colorectal cancer were included into this study from January to June 2009. The patients (35 cases of gastric cancer, 18 cases of colon cancer and 12 cases of rectal cancer) were randomly divided into experimental group (n=25) and control group (n=40). In experimental group, 400 mg sustained-releasing 5-fluorouracil was used. Blood samples were gained before operation, the second day and the seventh day after operation to examine the indexes of hepato-renal function, immune function and nutritional state. Complications， venting time and length of stay after operation were also recorded. Results There was no statistical significance for distribution of tumor stages and patients’ gender between experimental group and control group (Pgt;0.05). Preoperative indexes of hepato-renal function, immune function and nutritional state were also not reached statistical significance between two groups (Pgt;0.05). Compared with control group, the indexes of total protein and transferrin were decreased and urea nitrogen and IgM were increased in the second day after operation in experimental group (Plt;0.05). The number of lymphocyte was increased, while CD4, Alb, total protein and IgA were decreased in the seventh day after operation in experimental group, respectively. The time of passage of gas of experimental group was longer than that of control group (Plt;0.05).Conclusion Intra-abdominal implantation of sustained-releasing 5-fluorouracil is safe and feasible, which does not increase the complications and the time of length stay after operation. However, there is a little influence on immune function and gastrointestinal function after operation for intra-abdominal implantation of sustained-releasing 5-fluorouracil.
