Objective  To research the effect of ω-3 polyunsaturated fatty acid (PUFA) on inflammatory response and nutritional condition after operation for patients with gastrointestinal malignancies. Methods  Forty patients with gastrointestinal malignancies were included in this study from February 1st, 2009 to June 1st, 2009. Forty cases were randomly allocated to experimental group (20 cases) and control group (20 cases). Parenteral nutrition was conducted in continuous 7 days after operation. Comparing with control group, a dose of 10 g of ω-3 PUFA was given to experimental group every day in 7 days after operation in addition. Blood samples were gained before operation, the 2nd and 8th day after operation respectively to measure relative indexes about inflammatory response (WBC, neutrophilic granulocyte and C-reaction protein) and nutrition (total protein, albumin, prealbumin, siderophilin and lymphocyte). Reduction of body mass was also recorded. Results  The baseline between experimental group and control group was comparable (P gt;0.05). The levels of indexes about inflammatory response (WBC, neutrophilic granulocytem and C-reaction protein) and nutrition (total protein, albumin, prealbumin, siderophilin and lymphocyte) between experimental and control group did not reach statistically significant difference in the 2nd day after operation (P gt;0.05). The levels of neutrophilic granulocyte and C-reaction protein in experimental group were lower than those of control group, and the level of lymphocyte in experimental group was higher than that of control group in the 8th day after operation, and all of them reached statistical significance (P lt;0.05). There was no statistical different in reduction of body mass between experimentalgroupandcontrolgroup.Conclusion  ω-3 PUFA can depress the excessively inflammatory reaction and improve the nutritional condition of patients with gastrointestinal malignancies after operation.
