Analysis of plasma proteome from cases of the different traditional Chinese medicine syndromes in patients with chronic hepatitis B.
A proteomic analysis method, two dimensional gel electrophoresis (2-DE) followed by matrix-assisted laser desorption/ionization time-of-flight MS (MALDI-TOF-MS), was used to explore the link between plasma proteome and the different syndromes of traditional Chinese medicine (TCM) in patients with chronic hepatitis B (CHB). In compared with the plasma proteomes from health donors, the alterations in protein expression from cases of the five TCM syndromes, including damp heat stasis in the middle-Jiao syndrome, liver Qi stagnation and spleen deficiency syndrome, spleen and kidney Yang deficiency syndrome, liver and kidney Yin deficiency syndrome, and blood stasis into collateral syndrome with CHB were identified (P<0.05). In the cases of the five TCM syndromes with CHB, immunoglobulin J-chains (IGJ) and C-reactive protein (CRP) were up-regulated, while haptoglobin (HPT), retinol binding protein (RBP) and vitronectin were down-regulated. To further confirm these results, four proteins, including CRP, IGJ, HPT and RBP, from more plasma samples were quantified by ELISA. The results showed that the changes of protein levels were consistent with those from the 2-DE experiment. Importantly, the upregulation tendency of IGJ level in plasma is related with the different TCM syndromes with CHB (P<0.05). Our results show that IGJ may serve as a novel potential biomarker for diagnosis of the different TCM syndromes in patients with CHB.
