ABSTRACT

Objective:To investigate the significance of serum sP-selectin,sICAM-1 and immunoglobulin in the prognosis of hepatitis B cirrhosis.Methods:162 cases of hepatitis B patients with cirrhosis were treated as the research object in clinical laboratory of Chizhou People′s Hospital from January 2014 to December 2016,and detected in the serum of soluble P-selectin(sP-selectin), soluble intercellular adhesion molecule-1(sICAM-1),immunoglobulin and serum related index.Comparison of liver cirrhosis and liver cancer patients mean difference,Pearson analysis of serum soluble P-selectin(sP-selectin),soluble intercellular adhesion molecule-1 (sICAM-1),the correlation of immunoglobulin and serum indexes,logistic regression analysis of risk factors of liver cirrhosis to hepatocellular carcinoma,the receiver operating characteristic(ROC)OR>1 parametric curve evaluation of predictive value of hepatocellular carcinoma to liver cirrhosis.Results:The levels of sP-selectin,sICAM-1,IgM,IgG and IgA in patients with primary liver cancer were significantly higher than those in compensated cirrhosis and decompensated liver cirrhosis(P<0.05).The levels of sP-selectin,sICAM-1,IgM,IgG and IgA in patients with decompensated cirrhosis were significantly higher than those in decompensated liver cirrhosis(P<0.05).sP-selectin,sICAM-1,IgM,IgG,IgA were significantly higher in patients with grade C and grade B(P<0.05)in patients with different grades of cirrhosis.SP-selectin,sICAM-1,IgM,IgG,IgA were significantly higher in patients with grade B(P<0.05).There was no significant difference in the expressions of sP-selectin,sICAM-1 and immunoglobulin in patients with multiple foci of carcinoma and primary hepatocellular carcinoma(P>0.05).SP-selectin,sICAM-1 and immunoglobulin in patients with stage Ⅱprimary liver cancer were significantly higher than those in stage Ⅰ(P<0.05).There was a positive correlation between sP-selectin, sICAM-1 and immunoglobulin in patients with liver cirrhosis(P<0.05).In liver cirrhosis was the transfer of primary liver cancer as the dependent variable for Logistic regression analysis,the results showed that ALT,AST,sP-selectin,sICAM-1,IgM,IgG,IgA were risk factors of liver cirrhosis to hepatocellular carcinoma.ROC curve analysis showed that the sensitivity and specificity of sICAM-1 and sP-selectin in diagnosis of liver cirrhosis were higher than other factors.Conclusion:Serum sP-selectin,sICAM-1 has a higher accuracy of clinical diagnosis of hepatitis B cirrhosis prognosis evaluation,diagnostic specificity and sensitivity of liver cirrhosis to hepatocellular carcinoma was higher than that of simple detection of immunoglobulin,the combined detection in the diagnosis of liver cirrhosis is worthy of clinical prognosis.

ABSTRACT

BACKGROUND: The preliminary study found that domestic porous tantalum is conducive to the early adhesion and proliferation of MG63 cells, which can be used as a scaffold material for bone tissue engineering. As an optimized product of platelet-rich plasma, platelet lysate is more suitable for bone induction in the bone repair. OBJECTIVE: To further investigate the effect of platelet lysate and domestic porous tantalum scaffold constructs on the proliferation of MG63 cells and expression of integrin β1 (ITGβ1)/Vinculin/F-actin signaling pathway based on our previous findings. METHODS: MG3 cells were cultured and inoculated onto domestic porous tantalum scaffolds with the addition of 3%, 5%, 7% and 10% platelet lysates. Then, 7% as the best volume fraction of platelet lysate was screened by cell counting kit-8 method. There were four experimental groups including blank group (normally cultured MG63 cells), platelet lysate group (MG63 cells were cultured in 7% platelet lysate), porous tantalum scaffold group (MG63 cells were cultured on the domestic porous tantalum scaffold), and combined group (MG63 cells were cultured with 7% platelet lysate and porous tantalum scaffold. Scanning electron microscope was used to observe the surface morphology of domestic porous tantalum and platelet lysate-porous tantalum scaffold-MG63 cell complex. Cell counting kit-8 method was used to detect the proliferation of MG63 cells. Real-time fluorescence quantitative PCR (qPCR), immunocytochemical staining and western blot were used to detect the expression of ITGβ1, Vinculin, F-actin in MG63 cells at mRNA and protein levels. RESULTS AND CONCLUSION: Under the scanning electron microscope, MG63 cells adhered well to the scaffold surface. Compared with the blank group, the proliferation of MG63 cells could be significantly promoted by either platelet lysate or porous tantalum scaffold (P < 0.05). Moreover, the proliferation of MG63 cells was significantly improved in the combined group compared with the other three groups (P < 0.05). Findings from qPCR, immunocytochemical staining and western blot showed the highest expression of ITGβ1, Vinculin, F-actin mRNA and protein in the combined group (P < 0.05). These results indicate that platelet lysate and the domestic porous tantalum scaffold can synergistically promote the proliferation of MG63 cells, and up-regulate the expression of ITGβ1, Vinculin and F-actin mRNA and protein. Activation of the ITGβ1/Vinculin/F-actin signaling pathway may contribute to the proliferation, adhesion and differentiation of MG63 cells.
