[Changes of proteomic spectra of total flavones of Hippophae rhamnoides on myocardial protection].
OBJECTIVE
To study the mechanisms of the anti-myocardial ischemia of total flavones of Hippophae rhamnoides (TFH) at the level of proteome.


METHODS
Surface enhanced laser desorption/ionization (SELDI) mass spectrometry with protein chip IMAC3, SAX2 and NP20 was performed to compare the differentially expressed protein in myocardial ischemia in the TFH-treated groups with the 0.9% sodium chloride groups. Protein chips were examined in PBS II - C protein chip reader (ciphergen ciosystem inc) and the protein profiling was analyzed by Proteinchip Software 3. 0. 2.


RESULTS
The revealed six peaks had significant difference between the TFH-treated groups and the control groups, one of which were up-regulated in the TFH-treated groups, and the other were down-regulated. And in these six distinct proteins, there were four proteins on the IMAC3 chips and one protein on the SAX2 chips.


CONCLUSIONS
The TFH could prevent the myocardium from ischemia via regulating expression of different proteins.
