Résumé
IL-17 is one of more than 30 kinds of interleukin, which plays an important role in many biological processes. Under normal circumstances, IL-17 can cause inflammation. However, under pathological conditions, IL-17 can also promote a variety of tumors. Hepatocellular carcinoma (HCC) is the most common type of liver cancer.It has rapid development, poor prognosis, easy metastasis, and obvious inflammatory reaction in tumor microenvironment. These biological characteristics suggest that the occurrence and development of HCC are related to the expression of IL-17. IL-17 can affect the growth, development and autophagy of hepatocellular carcinoma through a variety of ways. For example, promot the growth of hepatocellular carcinoma through the AKT/IL-6/JAK2/STAT3 signaling pathway and the miR-383/STAT3 axis, increase the expression of MMPs by activating the NF-κB signaling pathway to promote hepatocellular carcinoma metastasis, enhance the expression of PIAS1 through the NF-κB pathway to inhibit the anti-tumor effect of IFN-γ, and by inhibiting the degradation of Bcl2 in Bcl2-Beclin1 to inhibit autophagy of hepatocellular carcinoma cells. This article reviews the research status of IL-17 in the pathogenesis of hepatocellular carcinoma.
Résumé
Fascin is an actin-bundling protein that is normally expressed in mesenchymal tissue and the nervous system. Many recent studies have shown that fascin was highly expressed in many human tumors and played a significant role in tumor proliferation, invasion, and metastasis. Fascin expression is also an independent factor correlated with poor patient prognosis and decreased survival rate. Fascin can be explored as a new molecular target for cancer treatment,thus can improve tumor patients' prognosis.
Résumé
Objective:To investigate the predictive value of P-selectin and D-dimer in the early diagnosis of portal vein thrombosis(PVT) in patients submitted to portal hypertension operation. Method:Eighty-two patients were assigned into two groups(PVT group and non-PVT group)after the operative treatment of portal hypertension.The levels of P-selectin and D-dimer were detected dynamically in the patients of two groups.Results:The preoperative levels of P-selectin and D-dimer in the PVT group were higher than those in the non-PVT group respectively(P
