AIM:To investigate the dynamic changes of serum hepatitis B surface antigen(HBs Ag) levels apportioned by the same hepatic parenchyma cell volume(HPCV),namely,hepatic cell quantities.METHODS:Serum HBs Ag levels were detected by electrochemiluminescence and serum HBs Ag levels apportioned by the same HPCV were figured out according to the theory of sphere geometry.HBs Ag levels were compared among different liver inflammation grades,as well as different hepatic fibrosis stages.RESULTS:In hepatitis B e antigen-negative chronic hepatitis B,serum HBs Ag levels in liver histological inflammation grades 1-4 were 3.66 ± 0.40,3.74 ± 0.35,3.74 ± 0.26 and 3.71 ± 0.34 log10 COI(cut off index),respectively,and there were no differences before apportion(P =0.640).Serum HBs Ag levels apportioned by the same HPCV were 5.57 ± 0.62,5.98 ± 0.65,6.59 ± 0.50 and 6.81 ± 0.84 log10 COI,respectively,and there were significant differences after apportion(P < 0.001).Serum HBs Ag levels in hepatic fibrosis stagesⅠ-Ⅳ were 3.66 ± 0.43,3.75 ± 0.33,3.71 ± 0.28 and 3.75 ± 0.26 log10 COI,respectively,and there were no differences before apportion(P =0.513).Serum HBs Ag levels apportioned by the same HPCV were 5.53 ± 0.66,5.98 ± 0.53,6.29 ± 0.46 and 7.06 ± 0.48 log10 COI,respectively,and there were significant differences after apportion(P < 0.001).CONCLUSION:Serum HBs Ag levels apportioned by the same HPCV(hepatic cell quantities),rather than serum HBs Ag levels,increase with liver inflammation grades and hepatic fibrosis stages.
AIM: To investigate the dynamic changes of serum hepatitis B surface antigen (HBs Ag) levels apportioned by the same hepatic parenchyma cell volume (HPCV), namely, hepatic cell quantities. METHODS: Serum HBs Ag levels were detected by electrochemiluminescence and serum HBs Ag levels apportioned by the same HPCV were figured out according to the theory of sphere geometry. HBs Ag levels were compared among different liver inflammation grades, as well as different hepatic fibrosis stages .RESULTS: In hepatitis B e antigen-negative chronic hepatitis B, serum HBs Ag levels in liver histological inflammation grades 1-4 were 3.66 ± 0.40, 3.74 ± 0.35, 3.74 ± 0.26 and 3.71 ± 0.34 log10 COI (cut off index), respectively, and there were no differences before apportion (P = 0.640). Serum HBs Ag levels apportioned by the same HPCV were 5.57 ± 0.62, 5.98 ± 0.65, 6.59 ± 0.50 and 6.81 ± 0.84 log10 COI, respectively, and there were significant differences after apportion (P <0.001) .Serum HBs Ag levels in hepatic fibro sis stages I-IV were 3.66 ± 0.43, 3.75 ± 0.33, 3.71 ± 0.28 and 3.75 ± 0.26 log10 COI, respectively, and there were no differences before apportion (P = 0.513) .Serum HBs Ag levels apportioned by the same HPCV were 5.53 ± 0.66, 5.98 ± 0.53, 6.29 ± 0.46 and 7.06 ± 0.48 log10 COI, respectively, and there were significant differences after apportion (P <0.001) .CONCLUSION: Serum HBs Ag levels apportioned by the same HPCV (hepatic cell quantities), rather than serum HBs Ag levels, increase with liver inflammation grades and hepatic fibrosis stages.
