Objective To evaluate dendritic cell vaccine immunotherapy in postoperative colorectal cancer patients. Methods 40 colorectal cancer patients were divided into two groups. Group A was not treated with the dendritic cell vaccine after chemotherapy, Group B was treated with four courses of autologous dendritic cell vaccine. The level of cytokines was tested before and after the therapy in both groups. DTH were tested after the last course of treatment. Results The levels of cytokines significantly increased in group B after vaccination compared with that in group B before vaccination and that in group A.8 patients were DTH positive in 15 patients that were tested after the vaccination. The PTS (progression-free survival) was 22 months in group B compared with 17 months in group A. The recurrence of the disease was not observed in patients with DTH positive. Conclusion DC vaccine in postoperative colorectal cancer patients improves the immune status and elicits tumor-specific response.

Objective To explore the value of terminal ileum suspension in the treatment of low rectal cancer.Methods 80 patients with low rectal cancer who underwent laparoscopic operation in our hospital from June 2015 to February 2017,were randomly divided into two groups:the control group (group C) and the test group (group T),40 cases in each group.In group C,laparoscopic radical resection of rectal cancer (Dixon) was performed and in group T Dixon was combined with terminal ileum suspension.Peripheral blood nutritional indicators (total plasma protein,albumin,pre-albumin,transferrin) and major electrolytes of two groups were observed 1 day before operation and 1,3 and 7 days after operation.The two groups were compared in terms of first exhaust time,postoperative hospital stay,total costs for hospitalization,postoperative discomforts and complications.Results There were no statistical differences in the levels of nutrition indicators and electrolytes between them (P ＞ 0.05) and neither it was with first exhaust time,hospital stay,total costs of hospitalization,incidence of postoperative discomforts and complications (P ＞ 0.05).The re-operation rate of group T with anastomotic leak was significantly lower than group C (P ＜ 0.05).Conclusion Terminal ileal suspension does not affect patients' postoperative recovery without increasing the patient's suffering and economic burden,and can effectively reduce the reoperation rate caused by anastomotic leak.It is easy to operate.

Interleukin-33 (IL-33) is a multifunctional gene in the interleukin-1 family and is widely expressed in human tissues. Its receptor is ST2, is associated with asthma, diabetes, Alzheimer's disease, cardiovascular disease, inflammatory bowel disease, and cancer. IL-33, enhancing lipid metabolism and down-regulating adipogenic gene expression by inducing Th2 cytokine production, plays a protective role in fatty liver. In hepatitis, the IL-33/NKT/IFN-γ pathway exacerbates mouse hepatitis. While, the IL-33/ILC2/IL-13/STAT6 pathway reduces liver damage. The IL-33/ILC2/IL-13/IL-4Rα/STAT6 axis plays a facilitating role in cirrhosis. In liver cancer, IL-33/ILC2/IL-13 signaling pathway is found to promote cholangiocarcinoma in a favorable pathological environment, and hepatocellular carcinoma occurs by IL-33/IL-6/JAK/STAT/Mcl-1 signaling pathway.
