新正天丸对偏头痛患者血小板5-HT2A受体和粘附分子表达的影响

目的探讨新正天丸对偏头痛患者血小板5-HT2A受体mRNA和粘附分子表达的影响及其相互的关系。方法将68例患者分为2组,治疗组(35例)口服新正天丸,对照组(33例)口服氟桂嗪胶囊。利用RT-PCR技术检测偏头痛患者血小板中的5-HT2A受体mRNA,应用流式细胞仪检测偏头痛患者全血血小板膜CD41和CD62P。结果治疗组疗效优于对照组。偏头痛患者5-HT2A受体mRNA的表达发作期与正常人有显著差异,经新正天丸治疗后可显著降低其表达。偏头痛患者发作期、间歇期血小板膜粘附分子表达均较正常人为高,而新正天丸能明显降低其表达。结论偏头痛患者5-HT2A受体mRNA的表达和血小板膜粘附分子的表达水平均显著增强,新正天丸可能通过降低上述指标的表达抑制血小板活化,从而达到治疗目的。

Effect of Xinzhengtian Pills on the Expression of 5-HT2A Receptor mRNA and Platelet Membrane Adhesion Molecules in Migraineurs

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.
