METHODS:Serum IL-18,IL-6 and IL-12 levels were measured by enzyme-linked immunosorbent assay (ELISA) from 70 patients with HCC and 10 healthy controls. RESULTS:Serum IL-18,IL-6 and IL-12 levels of patients with HCC were significantly higher that those of the controls. The levels of IL-18 correlated significantly with the presence of venous invasion and advanced tumor stages classified by Okuda's criteria. Patients with high serum IL-18 levels (≥ 105 pg/mL) had a poorer survival than those with low serum IL-18 levels (< 105 pg/mL) (4 and 11 mo,respectively,P = 0.015). Multivariate analyses showed that serum IL-18 level,but not IL-6 and IL-12 levels,was a significant and independent prognostic factor of survival. CONCLUSION:These findings demonstrate that serum IL-8 may a useful biological marker of tumor invasiveness and an independent prognostic factor of survival for patients with HCC. Thus,the detailed mechanisms of IL-18 involving in tumor progression should be further investigated.展开更多

This study was to investigate the serum levels of IL-18 and their clinical significance in patients with colore3ctaql carcinomas. Methods: Peripheral blood samples were obtained from 106 patients with colorectal carcinoma and 60 volunteers. The serum IL-18 levels were determined in each sample with an enzyme-linked immunosorbent assay (ELISA). Results: In patients before 1997, the mean IL-18 level was 338.46 pg/ml; in patients after 1997, the mean IL-18 level was 328.85 pg/ml, there is no evidence of loss of IL-18 immunoreactivity after prolonged storage at -80℃. The mean serum IL-18 level in 106 patients with colorectal carcinoma was significantly higher compared with the 60 healthy volunteers (P<0.05). Although the IL-18 level in patients with stage I did not differ from controls, the serum IL-18 levels of patients with stage II, stage III and stage IV disease were significantly higher compared with healthy control (P<0.05). The mean serum IL-18 level of patients with stage III disease, while the difference between patients with stage II and stage IV was not statistically significant (P>0.05). The survival rate of patients with IL-18 levels ≥346 pg/ml (n=47 patients) was significantly worse compared with patients who had IL-18 levels <346 pg/ml(n=57 patients). The 5-year-survival rates were 5.3% and 18.6%, respectively. Multivariate analysis using a Cox proportional hazards model identified the serum IL-18 level as an independent prognostic factor for survival Conclusion: The serum IL-18 level has a significant correlation with survival curve. The serum IL-18 level may represent a significant postoperative prognostic determinant in patients with colorectal carcinoma.展开更多

It is abundantly expressed in lung epithelial cells and plays an important role in both innate and adaptive immunity. In innate immunity, IL-33 responds promptly to produce an immune response that maintains homeostasis. In adaptive immunity, IL-33 interacts with various immune cells. At the same time, IL-33 also plays an important role in chronic inflammation of the airway and its remodeling. This article reviews the relevant biological knowledge of IL-33 and its research progress in lung immunity, and discusses the related issues of IL-33 as a lung immune test site and therapeutic target.展开更多

As new inflammatory mediators are characterized, it is important to understand their roles in sepsis. Interleukin 33(IL-33) is a recently described member of the IL-1 family that is widely expressed in cells of barrier tissues. Upon tissue damage, IL-33 is released as an alarmin and activates various types of cells of both the innate and adaptive immune system through binding to the ST2/IL-1 receptor accessory protein complex. IL-33 has apparent pleiotropic functions in many disease models, with its actions strongly shaped by the local microenvironment. Recent studies have established a role for the IL-33-ST2 axis in the initiation and perpetuation of inflammation during endotoxemia, but its roles in sepsis appear to be organism and model dependent. In this review, we focus on the recent advances in understanding the role of the IL-33/ST2 axis in sepsis.展开更多
