强化精氨酸肠内营养对烧伤患者营养状况和细胞免疫的影响

Objective To investigate the effects of arginine enriched enteral nutrition (EN) on nu-tritional status and cellular immunity of severely burned patients. Methods Randomized, single blind, parallel and positive control investigation was employed in the study. Thirty severely burned patients were di-vided into enteral immune nutrition (EIN) group and EN group. Sixteen patients in EIN group received en-teral nutrition enriched with arginine, while the other 14 patients in EN group received standard enteral nu-trition. Nutritional support was continued for 14 days. Gastrointestinal reaction of patients in 2 groups was observed. Fasting venous blood was drawn from patients of both groups before receiving nutrition treatment and on the morning of 7th, 14th day of treatment. Level of serum protein, hepatic function parameters, renal function parameters, fasting-blood glucose, and subpopulations of T lymphocytes in peripheral blood were determined. Results (1) Incidence of gastrointestinal side effect in EIN group (25.0%) was close to that of EN group (21.4% , P>0.05). (2) Compared with pre-treatment days, levels of prealbumin and transferrin in serum of patients in 2 groups on 7th and 14th post-treatment days were significantly increased (P<0.05 or P<0.01), but there was no significant difference between 2 groups. The level of total serum protein on 14th day of treatment of patients was significantly increased in both groups, and that of EIN group (66±7 g/L)was significantly higher compared with that in EN group (64 ± 11 g/L, P<0.05). The level of serum albumin (29±5, 32±5 g/L, respectively) of patients in EIN group on 7th and 14th day of treat-ment were significantly higher than that (26±4 g/L, P <0.05) in pre-treatment days, however there was no significant difference in EN group. (3) There was no significant difference in respect of hepatic function, renal function, and fasting-blood glucose between pre-treatment and post-treatment periods in both groups (P>0.05). (4) The ratio of CD4+ , CD8+ on 14th day of treatment in EIN group was close to that of pre-treatment level. In EN group, cell percentage of CD4+ significantly decreased, while that of CD8+ significantly increased (P<0.05), and CD4+ was significantly higher [(56±8) %] in EIN group than that in EN group [(55±12) % , P <0.05]. In both groups, cell percentage of CD3+ was significantly higher than that in pre-treatment days (P<0.05), while there was no obvious change in CD4+/CD8+. Conclusions Arginine enriched enteral nutrition can effectively improve nutritional status and cellular immune function of burn patients.

谷氨酰胺和生长激素对门静脉高压症患者术后营养、免疫和炎症反应的影响

Objective This study was conducted to evaluate the effects of postoperative glutamine and growth hormone on the nutritional status,immune function,and inflammatory responses of patients undergo-ing portal hypertension surgery.Methods This study was designed as a prospective,randomized and con-trolled clinical trial.Forty-two patients undergoing portal hypertension surgery were randomly divided into 2 groups:experimental group (receiving an immune enhancing parenteral nutrition by adding glutamine and re-combinant human growth hormone,n = 22),and control group (receiving an isocaloric and isonitrogenons standard parenteral nutrition,n = 20).Parenteral nutrition providing 125 kJ · kg-1·d-1 was initiated 3 days after surgery in both groups and last for 7 days.Blood samples were obtained on day 0th,3rd,and 10th.Host nutritional status was evaluated by measuring levels of prealbumin and transferrin,immunity was evalu-ated by measuring levels of CD4,CD8,CD4/CD8,IgG,IgM and IgA,and the inflanunatory responses was determined by assessing IL-2,TNF-α and C-reactive protein (CRP) levels.Results Ten days after opera-tion,among patients receiving an immune enhancing parenteral nutrition,the serum prealbumin was (193.84±39.78)mg/L,transferrin was (2.07±0.51)mg/L,CD4 was (33.7±5.5)%,CD4/CD8 was (1.17±0.32),IgG was (13.94±1.09)g/L and IL-2 was (368.12±59.25) pg/mL.They were signifi-cantly higher than those of the control group (P < 0.05).The TNF-α concentrations was (321.12±81.42)pg/mL and CRP was (32.2±15.2)mg/mL which were significantly lower than those of the control group (P < 0.05).Conclusion Postoperative administration of immune enhancing parentearl nutrition in patients undergoing portal hypertension surgery can improve nutritional status and immune function,and modulate inflammatory response is also better than standard one.
