老年气滞血瘀、气虚血瘀患者与CD62p、CD63及TSP关系的临床观察

目的：观察气滞血瘀、气虚血瘀与血板活化的关系。方法：采用流式细胞仪和特异性抗活性化血小板单克隆抗体对气滞血瘀、气虚血瘀患者118例的血小板活化分子α-颗粒膜蛋白（CD62p）、溶酶体完整膜蛋白（CD63）、凝血酶敏感蛋白（TSP）的表达量进行定量研究，同时测定血小板聚集功能。结果：气滞血瘀、气虚血瘀患者的CD62p、CD63、TSP的表达量皆显著高于正常对照组（30名，均P＜0．01）；气滞血瘀组CD62p、CD63、TSP的表达量皆显著高于气虚血瘀组（均P＜0．01）；CD62p与CD63、TSP均呈正相关（r=0.740,P<0.01;r=0.744,P<0.01),TSP与CD63呈正相关（r=0.635,P<0.01)，CD62p与ADP诱导的血小板聚集亦呈正相关（r=0.715,P<0.01).结论：血小板活化参与了血瘀证的发生与发展；血小板活化尤其与气滞血瘀关系密切。

Clinical Study on Relationship of CD62p, CD63 and TSP to the Qi-Stagnation Induced Blood-Stasis Syndrome and Qi-Deficiency Induced Blood-Stasis Syndrome in Aged Patients

OBJECTIVE: To observe the relationship of platelet activation to the Qi-stagnation induced blood-stasis (QSBS) or Qi-deficiency induced blood-stasis (QDBS) syndrome. METHODS: Expressions of platelet activating molecules, including alpha-granule membrane glycoprotein (CD62p), lysosomal integral membrane protein (CD63) and thrombospondin (TSP), in patients with QSBS and QDBS were determined quantitatively with flow-cytometry and specific monoclonal antibody against activated platelet. And platelet aggregation was tested simultaneously. RESULTS: CD62p, CD63 and TSP expressions in Blood-Stasis patients, both QSBS and QDBS, were higher than those in the normal control significantly (all P < 0.01); all the three expressions were higher in QSBS group than those in QDBS group (all P < 0.01), Positive correlation was shown between CD62p and CD63 (r = 0.740, P < 0.01), CD62p and TSP (r = 0.744, P < 0.01), TSP and CD63 (r = 0.635, P < 0.01), and between CD62p and ADP induced platelet aggregation (r = 0.715, P < 0.01). CONCLUSION: Platelet activation was involved in the pathogenesis and development of Blood-Stasis Syndrome, especially closely related with the QSBS Syndrome.
