OBJECTIVE: To study the effects of fibroblast growth factor-21 (FGF-21) on acute inflammation induced by lipopolysaccharide (LPS) and its mechanism. METHODS: Mouse model of acute inflammation was established by injection of LPS and treated with FGF-21 at high, medium and low doses, the pathological changes were detected with HE staining, the expression level of TNF-α, IL-1β, IL-6 and IL-17 in serum and peritoneal macrophage were determined by ELISA and Real-time PCR. NF-κB p65 in macrophage cells was analyzed by confocal laser scanning microscope and Western-blotting. RESULTS: FGF-21 treatment reduced lung damage and inflammatory cell infiltration and decreased the expression level of TNF-α, IL-1β, IL-6 and IL-17 in both serum and peritoneal macrophage. The results of confocal laser scanning microscope and Western-blotting both showed that FGF-21 could inhibit NF-κB transferring to the nucleus. CONCLUSION: FGF-21 could regulate the immune system by acting on macrophage. Relieving the inflammatory response in mice through NF-κB signal pathway may be one of the mechanisms FGF-21 regulating immune system.

Objective To investigate the clinical values of extracapsular invasion at sentinel lymph nodes in patients with breast cancer.Methods From Jan,2010 to Jan,2013,80 patients underwent axillary lymph node dissection due to sentinel lymph nodes invasion were enrolled in this prospective study.Patients were signed to extracapsular at sentinel lymph nodes positive group (n =45)and control group (n =35)according to the intra -operative pathology.The primary outcome was rate of positive non -sentinel lymph nodes and the second outcomes were 3 -year recurrence -free survival,mortality and health -related quality of life.Results Compared with the control group,the patients in extracapsular at sentinel lymph nodes positive group got a significantly higher rate of positive non -sentinel lymph nodes (91.11% vs.28.57%,χ2 =33.321,P <0.001 );a significantly lower rate of 3 -year recurrence -free survival(57.78% vs.88.57%,χ2 =9.114,P =0.003);a significantly higher rate of mortality (17.78% vs.2.86%,χ2 =4.390,P =0.036);and a significantly lower level of health -related quality of life[(78.43 ±12.43)vs.(87.54 ±11.89),t =11.324,P =0.000].Conclusion Extracapsular invasion at sentinel lymph nodes was a reliable predictor for non -sentinel lymph nodes invasion and long -term clinical outcomes.
