Objective To investigate clinical significance of the changes in the peripheral blood T lymphocytes subsets in patients with diseases related to HBV infection .Methods 257 cases of inpatients and outpatients were selected from Jan .to Dec .2013 ,and were divided into hepatitis B carriers (ASC)group ,chronic hepatitis B(CHB)group ,hepatocirrhosis(LC)group and primary liver cancer(PHC)group according to types of diseases related to HBV infection .Other 50 healthy individuals conducted physical exami‐nation were enro1led in the control group .The absolute CD3+ ,CD4+ and CD8+ T‐cell count ,and CD3+ ,CD4+ and CD8+ percent‐age and CD4+ /CD8+ value were detected in all subjects by using flow cytometer .These data were compared and analyzed .Results Compared with the control group ,there were no significant differences of the absolute CD3+ ,CD4+ and CD8+ T‐cell count ,and CD3+ ,CD4+ and CD8+ percentage and CD4+ /CD8+ value in ASC group ,CHB group and LC group(P>0 .05) .Compared with the control group ,the absolute CD4+ T‐cell count ,CD4+ percentage and the CD4+ /CD8+ value were decreased in the PHC group , while the CD8+ percentage were increased in the PHC group ,there were statistical significant differences between the two groups (P<0 .05) .Conclusion The peripheral blood T lymphocyte subsets could be monitor indexes of cell immune function in diseases related to HBV infection .

]. Conclusions The monoclonal-based ECLIA is a sensitive, specific, and rapid method and no radiocontamination. It can be used to detect hanum serum proinsulin in type 2 diabetes.
