Abstract:
Objective To investigate changes in the expression of 5-HT2A receptor mRNA and platelet membrane adhesion molecules in migraineurs during the periods of attack and intermittence therapy by Xinzhengtian Pill (XZTP). To study the interrelation between the expression of 5-HT2A receptor mRNA and platelet membrane adhesion molecules. Methods 68 patients were randomly divided into XZTP (therapy) group and Flunarizine (control) group. The RT-PCR method and the image pattern analysis semiquantitation method were used to determine the 5-HT2A receptor mRNA expression levels in the migraineur groups and the normal control group. Flow cytometry was used to detect the expression of whole blood platelet membrane adhesion molecules in those groups. The interrelation between the expression of 5-HT2A receptor mRNA and adhesion molecules was analysed. Results The total effect have show obvious difference between therapy group and control group. 5-HT2A receptor mRNA in the attack group was higher than that of the intermittence group and the normal group, and XZTP can reduce this expression. The expression of whole blood platelet membrane adhesion molecules had a higher increase during the periods of attack and intermittence, compared with the normal control group and XZTP. The 5-HT2A receptor mRNA expression level in the migraineur groups had a high positive correlation with CD41 and moderate positive correlation with CD62P. Conclusion 5-HT2A receptor mRNA and platelet membrane adhesion molecule expression level during the period of attack was significantly augmented and platelet activation was increased. XZTP maybe restrained the expression of above indexes and resulted in platelet activation reduced.
