目的 :探讨脑梗死患者血浆CD6 2p水平的变化和其在脑缺血损伤中的作用。方法 :用流式细胞术检测 15 0例脑梗死患者及 30例正常对照者血浆CD6 2p含量变化。结果 :发病后各组血浆CD6 2p含量显著升高 ,并且在脑梗死不同病程时的差异有显著意义。结论 :CD6 2p参与了缺血性脑损伤的病理过程 ,可作为判断病情的指标。 Objective: To investigate the change of plasma CD6 2p level in patients with cerebral infarction and its role in cerebral ischemia injury. Methods: The changes of plasma CD6 2p levels in 150 patients with cerebral infarction and 30 normal controls were detected by flow cytometry. Results: After the onset of the disease, the levels of plasma CD6 2p in each group were significantly increased, and the differences were significant in different stages of cerebral infarction. Conclusion: CD6 2p is involved in the pathological process of ischemic brain injury and can be used as an index to judge the disease.
