[Effects of Early Enteral Immunonutrition on Postoperative Immune Function and Rehabilitation of Patients with Gastric Cancer and Nutritional Risk].

OBJECTIVES: To investigate the effects of early enteral immunonutrition on postoperative immune function and rehabilitation of gastric cancer patients with nutritional risk. METHODS: New hospitalized patients with gastric cancer were evaluated the nutrient status based on NRS 2002. The patients who scored between 3 to 5 points were randomized into two groups(30 cases for each group), and those in experimental group were given 7-d early postoperative enteral immune nutrition, those in control group were given normal nutrition. The immune indexes (CD3+, CD4+, CD8+ and CD4+/CD8+) and nutritional indexes(transferrin, pre-albumin, albumin) were measured before operation and at the 3rd and 7th day postoperatively. In addition, the first flatus time, gastrointestinal adverse reactions and complications, length of hospital stays were compared between the two groups. RESULTS: The level of CD4+/CD8+ and transferrin, pre-albumin, albumin in experimental group were significantly higher than those in control group at the third and seventh day postoperatively (P<0.05).Compared with the control group, the experimental group had shorter first flatus time after surgery, which were (63.5±7.3) h vs. (72.8±8.6 ) h respectively (P<0.05).There were no statistically difference on pneumonia, anastomosis leakage, severe abdominal distension, inflammatory bowel obstruction and total postoperative hospitalization time between the two groups (P>0.05). CONCLUSIONS: Early enteral immunonutrition can effectively promote the recovery of nutritional status and immune function in gastric cancer patients with nutrition risk.

[Relationship of IFRD1-rs3807213 gene polymorphism with the risk of gastric cancer among Chinese].

OBJECTIVE: To investigate the association between rs3807213 gene polymorphism in interferon related developmental regulator 1 gene (IFRD1) and the risk of gastric cancer among Chinese. METHODS: There were 53 gastric cancer patients and 50 healthy people included in this case-control study. The blood samples were collected from each observed object and genotype (AA, AC, CC) of IFRD1 rs3807213 SNP was detected after polymerase chain reaction (PCR). The relationships of rs3807213 gene polymorphism with gastric cancer risk, clinic and pathologic features were analyzed. RESULTS: Patients with stomach cancer had a significantly higher frequency of rs3807213 C allele distributions (OR = 3.759, 95% CI = 1.521-9.294; P = 0.003) than the controls. Compared with control group, patients with gastric cancer had a significantly higher frequency of rs3807213 CC genotype (OR = 4.028, 95% CI = 1.513-10.720; P = 0.004). When stratified by pathological stage of gastric cancer, there was no significant difference observed. CONCLUSION: IFRD1-rs3807213 polymorphism may be associated with the increased risk of gastric cancer.
