ABSTRACT
Objective To investigate the clinical value of combined test of prealbumin (PA),total bile acid(TBA)and liver bi-opsy in chronic hepatitis.Methods 172 patients hospitalized with chronic hepatitis in the Affiliated Hospital of Yan’an Uni-versity Medical College from October,2013 to March,2014 was collected as the chronic hepatitis group;and 45 cases of nor-mal healthy control of the corresponding period was collected as the control group.Prealbumin,TBA was detected respec-tively in the two groups.Immunoturbidimetry was adopted in PA,Enzymatic cycling assay was employed in TBA,and at the same time percutaneous puncture of liver histology was detected in the chronic hepatitis group.Results The PA in the chro-nic hepatitis group (179.12±8.46 mg/L)was lower than the control group (257.34±6.38 mg/L),and the difference was statistically significant (P <0.05).The TBA in the chronic hepatitis group (30.58±9.37 μmol/L)was higher than the con-trol group (8.16±1.59 μmol/L)and also the difference was statistically significant (P <0.05).PA was negatively correla-ted with the pathological grades (rs =-0.617,P <0.05),and TBA was positively correlated with pathological grades (rs =0.724,P <0.05).The separate diagnostic positive rate of PA was 58.7% (101/172),while the TBA was 93.6% (161/172).The combined diagnostic positive rate of the two was 93.6% (161/172),it was higher than the separate rate and was statistically significant (P <0.05).Conclusion The serum levels of PA and TBA can reflect the extent and degree of hypo-hepatia and hepatic inflammation,and the combined detection of the two will be much sensitive to the diagnosis of chronic hepatitis,and compared with histological detection,it is convenient,simple,and easy to operate.
