血瘀证与血小板粘附分子的研究

【目的】观察气滞血瘀、气虚血瘀与血小板活化的关系。【方法】采用单克隆抗体和流式细胞仪技术 ,研究不同病种气滞血瘀和气虚血瘀患者血小板活化分子溶酶体完整膜蛋白 (CD 6 3)、α -颗粒膜蛋白 (CD 6 2p)及凝血酶敏感蛋白 (TSP)阳性细胞百分率的变化。【结果】气滞血瘀组的血小板CD 6 3、CD 6 2p、TSP表达量明显高于气虚血瘀组及正常对照组 (P <0 .0 0 1) ;气虚血瘀组的血小板CD 6 3、CD 6 2p、TSP表达量亦明显高于正常对照组 (P <0 .0 5) ;气滞血瘀患者心、脑血管两种疾病之间的血小板CD 6 3、CD 6 2p、TSP表达量无差异 ;气虚血瘀组心、脑血管两种疾病之间的血小板CD 6 3、CD 6 2p、TSP表达量亦无差异。【结论】血小板活化参与了血瘀证的发生与发展 ,而不同证型的血瘀证影响了血小板活化的表达 ,不同病种之间的血小板活化表达量则无差异。

Clinical Study on Relationship Between Blood Stasis Syndrome and Platelet Adhesion Molecules

Objective To explore the relationship between Qi_stagnation with blood stasi s, Qi_deficiency with blood stasis and platelet activation. Methods Expressi on levels of lysosomal integral membrane protein (CD?63), alpha_granu le membrane protein (CD?62?p) and thrombospondin (TSP)were the specific index es of platelet activation. Te chnique of monoclonal antibody analysis and flow cytometry were used to detect the expression levels of CD?63, CD?62?p and TSP. Fifty_eight cases of Qi_st agnation with blood stasis syndrome were allocated to Group A and 60 cases of Qi _deficiency with blood stasis syndrome to Group B, and 30 healthy volunteers ser ved as the control (Group C). Results Expression levels of CD63, CD62p an d TSP were higher in Group A than in Group B and Group C (P< 0.001 ), and were also higher in Group B than in Group C (P < 0.05 ). The differences of CD?63, CD?62?p and TSP exp ressio n levels in Group A suffering from cardiovascular diseases and cerebrovascular d iseases were not significant, so did in Group B. Conclusion Platelet activation is involved in the pathological proc ess of blood stasis syndrome. Expression of CD?63, CD?62?p and TSP varies in Qi_stagnation with blood stasis syndrome and Qi_deficiency with blood stasis syn drome but has no relation with different diseases.
