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.

无血清培养的CD3AK细胞对烧伤患者免疫功能的调理作用

感染及并发症是大面积烧伤患者的主要死亡原因。研究证明，烧伤后机体各种免疫机能均呈现不同程度的抑制状态，这一变化与烧伤后感染及各种并发症的发生、发展关系密切。因此，尽早逆转和纠正烧伤后免疫功能抑制状态、提高烧伤患者全身免疫功能是防治烧伤感染、提高大面积烧伤患者治愈率的重要环节，也是目前烧伤治疗中亟待解决的问题。
