Objective To analyze the differential proteomic profiles of the plasma in patients with chronic hepatitis B presenting with damp- heat retention syndrome and liver stagnation- spleen deficiency syndrome. Methods Two- dimensional polyacrylamide gel electrophoresis(2- DE) and matrix- assisted laser desorption ionization time- of- flight mass spectrometry(MALDI-TOF MS) were used to identify the differentially expressed proteins in the plasma of patients with chronic hepatitis B.Results The numbers of plasma pr...
