Many malignant tumor have methionine dependency. Methionine restriction can inhibit proliferation of tumors cells by decreasing the level of methionine with depriving methionine, methioninase, homocysteine, and its analogs.Methionine restriction may act synergistically with chemotherapies to increase their efficiency and /or reduce their toxic side effects.Therefore, methionine restriction would become a new cancer treatment.

Whey protein has high biologic value and absorption rate.In its purest form, whey protein contains little fat,lactose or cholesterol and is a rich source of branched chain amino acid and bioactive peptides.The broad application prospect of whey protein on nutrition,medical care and food making are stressfully discussed.It provides a number of benefits in areas including cardiovascular, diabetes,immune support,infant nutrition,aging postpone,and general wellness etc.

With the development of society and living condition,the incidences of fatty liver and other diseases like hypertension,cardiovascular disease and diabetes have increasd by several factors.This review discussed the cause,mechanism and therapy of fatty liver.The emphasis was put on the object and principle of nutritional therapy.Generally,the treatment of fatty liver includes control of the underlying causes,nutritional therapy,proper physical exercise,upbeat life-rhythm and a certain workload.Plasmapheresis and oxygen therapy are the new methods.

Objective:To develop continual medical education and research talented persons of clinical nutritional support.Methods: By constructing formatting five shoring and optimizing ensuring system to explore,innovate and develop the items of continual medical education.Results:A lot of innovation topics, new medical bases, talented men and innovation achievements were accomplished.Conclusion:Continual medical education is an effective way to culture the talented persons in clinical nutritional support.

Objective: To investigate the treatment effect of rational enteral nutrition in stress ulcer bleeding after severe brain injuries.Methods: 30 cases with severe brain injuries accompanied with stress ulcer bleeding were supported by enteral nutrition as clinical treatment group.50 cases with the same conditions were managed with traditional treatment methods as control.Results: All patients in clinical treatment group had no stress ulcer bleeding any more. The nutritional state was improved. On the other hand,the stress ulcer bleeding occurred again and again and the nutritional state was poor.Conclusion: Rational enteral nutrition can treat upper gastrointestinal stress ulcer bleeding in severe brain injuries effectively.

Objective: To explore the effects of growth hormone (GH) added early enteral nutrition(EEN) on nutrition status and complications in postoperative hypertensive intra-cerebral hemorrhage(HICH) patients.Methods: 122 patients with postoperative HICH were randomized into the treat group and control group. The treatment group (61 cases) received enteral nutrition support on the 2nd day after operation, and growth hormone was combined for one week. The control group (61 cases) received total parenteral nutrition(TPN) support. The clinical effect and complications were observed between the two groups. Results: The patientss serum pre-albumin , transferrin ,albumin , and nitrogen balance in the treatment group were significantly better than those in the control group (P

Objectives: To investigate the effects of the extract mixture of alfalfa and perilla on lowering serum lipid, protecting liver and aortic wall in rats. Methods: Sixty SD rats were divided into six groups and were fed different diet. After seven or fourteen days, the rats were put to death and measured for serum lipids, cholesterol content of liver and aortic wall, and pathological change of the tissue. Results: There was a significant increase of serum TC, LDL-C, cholesterol content of liver and aortic wall in the high-fat fed rats. Under light microscope, there were lipid droplets and cholesterol crystal in liver of group high-fat. Compared with the group high-fat, the rats had a significant decrease of those measurements in serum or in tissue in the alfalfa and perilla group. Conclusions: The extract mixture of alfalfa and perilla could prevent the increase of serum TC, LDL-C, cholesterol content of liver and aortic wall in high-fat fed rats, and also prevent the fatty infiltration and cholesterol deposit of liver.

Objectives: To investigate the distribution of common pathogens and their antibiotic resistance from patiens with catheter related sepsis (CRS).Methods: Catheter bacteria cultrure and antibiotic sensitivity test were performed from 69 patiens with CRS.Results: The common pathogens in CRS were fungi (41.1%),Gram-positive cocci (35.6%)and Gram-negtive bacilli (23.3%). Non-C. albicans species were major pathogen (19/30 stranins).The most strains were staphylococcus epidermidis in Gram-positive cocci and the most of them were Methicillin resistant.No vancomycin resistant strains were found. The Gram negative bacilli were often resistant to third generation cephalosporens.Conclusions: The dorminant pathogens of CRS are fungi and gram positive cocci and we should pay more attention to pathogens of resistence to antibiotics. In order to control CRS, CVC must be used reasonably and shorten the duration of retention.

Objective: To observe the effects of early enteral nutrition(EEN) on incidence of postoperative complication in gastric cancer patients. Methods: 150 patients with gastric cancer were randomly divided into early enteral nutrition group (n=82) and non-early enteral nutrition (N-EEN) group (n=68). The patients in group EEN were given enteral nutrition after operation, and the patients in group N-EEN were given total parenteral nutrition support. The postoperative complications were recorded. The serum albumin, prealbumin and transferrin were measured on postoperative day 1, 5 and 9. The serum level of alanine aminotransferase(ALT), bilirubin, blood urea nitrogen(BUN), creatinine, glucose, cholesteroland triglyceridewere monitored. Results: The complications occurred in 21patients. 5 of these patients belonged to EEN group and the other belonged to N-EEN group. In EEN group, the serum albumin, prealbumin and transferrin were significantly higher than in N-EEN group on postoperative day 9 (P

Objective: To evaluate the effect of nutritional support for lung transplantation patients.Methods: The lung transplantation patient received perioperative enteral nutrition(EN) .Exogenous glutamine(Gln) and recombinant human growth hormone(rhGH) were postoperatively used for 7-14 days.Results: The patients weight increased from 53 kg to 55 kg. No respiratory failure and acute rejection occurred postoperatively. The patient recovered fluently.Conclusion: Appropriate perioperative nutritional support and postoperative metabolic intervention can facilitate the recovery of lung transplant patient.
