[Serum proteomics study of chronic gastritis with dampness syndrome in traditional Chinese medicine].

Objective: To explore microcosmic information in chronic gastritis dampness syndrome by using serum proteomics of patients with chronic gastritis dampness syndrome.
Methods: Serum proteomics of 18 dampness syndrome cases, 17 non-dampness syndrome cases in chronic gastritis patients and 8 normal controls were analyzed by surface enhanced laser desorption/ionization-time of flight (SELDI-TOF) protein-chip.
Results: There was a high expression trend in three ratios of charge (of an electron) to mass (M/S) of 3.2 kD, 6.4 kD and 8.1 kD of protein expression spectrum from patients with chronic gastritis dampness syndrome, and the wave peak value was over 10 units. There was a low expression trend in above-mentioned sites of protein expression spectrum from patients with chronic gastritis non-dampness syndrome and normal group. The wave peak value of patients with chronic gastritis non-dampness syndrome was about or below 10 units, and the wave peak value in normal group was below 5 units.
Conclusion: There exists a certain significance to explore biologic theory basis of chronic gastritis dampness syndrome by analyzing the serum proteomics.
