Results: (1) The cell CCK-8 OD value in normal group,103 cp/ml group and 106 cp/ml group were 0.402 ± 0.168,0.267 ± 0.156,0.246 ± 0.179 respectively. The cell CCK-8 OD value in 103 cp/ml group and 106 cp/ml this website were significantly lower than that of the normal group (t = 2.733,3.178, all p < 0.05).(2) Different viral load of hepatitis B could significantly inhibit the colony

formation of megakaryocyte. The number of colony formation in normal group, the 103 cp/ml group and 106 cp/ml group were 49.0 ± 3.399, 31.5 ± 2.991,27.4 ± 3.062, the difference among these groups were significantly (F = 132.142 p < 0.01). And the number of colony formation in 103 cp/ml group

were significantly higher than that of in the 106 cp/ml group (t = 2.906, p < 0.01).(3) The CD41 expression of megakaryocytes in normal group, the 103 cp/ml group and 106 cp/ml group were 36.46 ± 20.941,57.78 ± 19.531,79.9 ± 16.897. The CD41 expression of megakaryocytes in the 103 cp/ml group and 106 cp/ml was significantly increased compared with the nomal group (t = 3.865,2.191, p < 0.05), and the CD41 expression of megakaryocytes in the selleck chemicals 103 cp/ml group was lower than that of in the 106 copies/ml group (t = 2.273, p < 0.05). Conclusion: Different concentrations of viral load in hepatitis B cirrhosis patients could affect the proliferation and differentiation of megakaryocytes in vitro. Different concentrations of hepatitis B viral load had a different inhibitory effect on the proliferation of megakaryocytes in vitro, the greater the viral load, the greater the inhibition. But different concentrations of hepatitis B viral load could stimulate the differentiation of megakaryocytes. Key Word(s): 1. Liver cirrhosis; 2. Megakaryocytes; 3. Cell proliferation; 4. cell differentiation;

Methods: According to Child – Pugh classification standard, hepatitis B cirrhosis patients could be divided into group A, group B and group C, compared to normal people, using flow cytometry to detect CD62P, CD63 positive percentage, platelet aggregation analyzer to detect PAgT, and biotin double antibody sandwich enzyme-linked immunosorbent method to detect the contents of PEDF.
