The development and progression of the disease is fostered by inflammatory cells and cytokines. One of these cytokines is interleukin-6(IL-6), which plays an important role in a wide range of biologic activities.DATA SOURCES: A systematic search of PubMed was performed to identify relevant studies using key words such as interleukin-6,inflammatory cytokines, inflammation and pancreatic cancer or PDAC. Articles related to IL-6 and pancreatic cancer were systematically reviewed.RESULTS: IL-6 is elevated in the serum of pancreatic cancer patients and correlates with cachexia, advanced tumor stage and poor survival. Its expression is enhanced by hypoxia and proteins involved in pancreatic cancer development like Kras,mesothelin or ZIP4. IL-6 in turn contributes to the generation of a pro-tumorigenic microenvironment and is probably involved in angiogenesis and metastasis. In experimental mouse models of PDAC, IL-6 was important for the development and progression of precursor lesions.CONCLUSION: IL-6 emerges as a key player in pancreatic cancer development and progression, and hence should be considered as a new therapeutic target.展开更多

Methods: Serum levels of interlukin-2 and its soluble receptor and interlukin-6 were measured by ELISA in 34 patients with recurrent genital herpes. Results: Serum levels of IL-2 and IL-6 were significantly decreased in patients compared to healthy controls (P<0.01),and the level of sIL-2R was significantly increased in patients with recurrent genital herpes (P<0.01). There were nosignificant differences in all variables amongst patients regarding relapse stage and remission stage (P >0.05). Conclusion: There was a cellular immune deficiency in patients with recurrent genital herpes.展开更多

Methods: A total of 36 out and in patients with chronic bronchitis including 10 cases of asthma were subjected into this study. Among them, 20 cases were qi deficiency type and 16 qi yin deficiency with phlegm damp type. The changes of symptoms, T lymphocyte subgroups of CD 3 +, CD 4 +, CD 8 +, CD 4 +/CD 8 +, soluble interleuki 2 receptor (SIL 2 R), interleukin 6(IL 6), IgG, IgA and IgM before and after treatment were observed and detected using monoclonal indirect fluorescence method, enzyme linked immunosorbent assay (ELISA) and nephelometry respectively. Results: (1)The effective rate of qi dificiency type was 100% and that of qi yin deficiency with phlegm damp type 87.5%. (2) After acupuncture treatment, in qi deficiency type patients, serum IgG, IgA and IgM contents increased significantly (P<0.001) in comparison with pre treatment and in qi yin deficiency with phlegm damp type patients, IgG level lowered obviously. Serum SIL 2R and CD 4 +/CD 8 + decreased obviously (P<0.01, 0.001), CD 3 +, CD 4 + and CD 8 + increased evidently (P<0.01). Conclusion: The Fifty ying acupuncture therapy can better clinical symptoms of chronic bronchitis patients through its resultant up regulation of the immune system function.展开更多
