Their clinical data and blood samples were collected, and serum was prepared and stored at-73℃. Anti-HBx was detected with an indirect ELISA established in our earlier research, and levels of IL-10, IL-12 and Fas were determined with commercial double-antibody sandwich ELISA kits. The mutual relationship between anti-HBx and IL-10, IL-12 or s Fas in serum were analyzed with the software SPSS 20.0. Results All levels of IL-10, IL-12 and s Fas in peripheral blood showed a rising trend with development of chronic HBV infection. The levels of IL-10 in ASC, CHB, LC and HCC groups were 13.93 ± 14.40 ng/L, 39.38 ± 20.77 ng/L, 69.06 ± 46.37 ng/L and 62.82 ± 23.42 ng/L, respectively, levels of IL-12 in the 4 groups were 15.64 ± 23.04 ng/L, 68.50 ± 23.14 ng/L, 76.83 ± 12.82 ng/L and 83.74 ± 24.88 ng/L, respectively, and levels of s Fas were 58.17 ± 77.42 ng/L, 179.88 ± 104.36 ng/L, 249.22 ± 107.80 ng/L and 252.98 ± 87.65 ng/L, respectively. Twenty-seven out of 90 patients showed a positive result for anti-HBx detection, including 1 in ASC, 4 in CHB, 12 in LC and 10 in HCC group. The levels of IL-10, IL-12 and sF as were higher in anti-HBx positive group than in negative group. Statistical analysis demonstrated significant differences of IL-10 and IL-12 between the two groups(P < 0.05), but the differences of s Fas had no statistical significance(P = 0.094). Conclusions Anti-HBx antibody is not protective, and is closely related to IL-10, IL-12 and s Fas. It may be an important serum indicator for aggravation from chronic hepati展开更多

A heavy hammer or a small type of rocket is used to strike the pile top and the detectors are used to record vibra- tion graphs. An expression of higher degree of strain (deformation force) is introduced. It is testified theoretically that the displacement, velocity and acceleration cannot be obtained by simple integral acceleration and differential velocity when long displacement and high strain exist, namely when the pile phase generates a whole slip relative to the soil body.
