Proteomics study on the essence of wind syndrome caused by gan-yang hyperactivity in Chinese medicine / 中国中西医结合杂志

ABSTRACT

<p><b>OBJECTIVE</b>To preliminarily study the essence of wind syndrome caused by Gan-yang hyperactivity (WSGH) in Chinese medicine at the protein expression level.</p><p><b>METHODS</b>WSGH was strictly differentiated from wind stirring due to yin deficiency syndrome in patients with intracerebral hemorrhage (ICH) and those with cerebral infarction (CI); from Gan-yang hyperactivity syndrome in patients with cervical spondylosis (CS); from wind syndrome induced by blood deficiency in patients with Parkinson's disease (PD) according to Chinese medicine syndrome typing standard. Control studies were performed. Peripheral blood mononuclear cells (PBMCs) were isolated from all patients of the aforesaid syndromes and healthy subjects. The total proteins were extracted, two-dimensional gel electrophoresis (2-DE) conducted and analyzed by PDQuest software. The peptide mass fingerprint (PMF) was determined using matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS). The SwissProt database was inquired using Mascot reference system. Proteins of different and same expressions in PBMCs of patients suffering from the same disease of different syndromes, different diseases of the same syndrome, and syndromes of the same kind were compared.</p><p><b>RESULTS</b>The 2-DE map of PBMCs' total proteins in the aforesaid syndrome groups and healthy subjects was established. Through comparison, analysis, and appraisement, there was 1 protein dot of the same expression and 22 protein dots of different expressions between ICH patients of WSGH and ICH patients of wind stirring due to yin deficiency syndrome. There were 6 protein dots of the same expression and 21 protein dots of different expressions between CI patients of WSGH and CI patients of wind stirring due to yin deficiency syndrome. There were 3 protein dots of the same expression and 12 protein dots of different expressions between CS patients of WSGH and CS patients of Gan-yang hyperactivity syndrome. There was no protein dot of the same expression and 12 protein dots of different expressions between PD patients of WSGH and PD patients of wind syndrome induced by blood deficiency. There were 13 protein dots of the same expression in different diseases of the same syndrome. There was 1 protein dot (Thioredoxin-dependent peroxide reductase, TPx) of the same expression in the four diseases of the same kind syndrome.</p><p><b>CONCLUSIONS</b>Different connotations of the essence existed (having multiple different protein expressions) in patients with the same disease of different syndromes. Syndromes of the same kind share the same material bases (having the same protein expression). These suggested that Chinese medicine syndrome has its own material bases and essence findable.</p>
