| 中文摘要: |
| 目的：观察清开灵注射液对大鼠脑梗死缺血性损伤急性期阶段，不规则趋化因子（Fractalkine，FKN）的表达变化，探讨清开灵注射液治疗急性脑缺血的可能机制。方法：线栓法制备大鼠大脑中动脉永久性梗死模型(MCAO)，随机分为假手术组、模型组，清开灵注射液观察组，TTC染色观察大鼠治疗前后脑组织梗死体积变化，同时采用蛋白芯片、ELISA和免疫组化法分别检测脑脊液、外周血清及脑组织中FKN的表达水平。结果：脑组织TTC染色显示模型组均出现明显梗死灶，清开灵观察组的梗死体积明显缩减。与模型组比较，清开灵观察组明显下调病变局部脑组织的FKN（P<0.05），且能明显上调血清中的FKN（P<0.05），同时观察到其可上调脑脊液及全脑的FKN，差异无统计学意义（P>0.05）。结论：清开灵注射液能缩小脑梗死体积，减轻急性脑缺血性损伤，其机制可能与调节FKN的表达有关。 |
| English Summary: |
| To observe the expression changes of irregular chemokine (Fractalkine，FKN) in the acute phase of ischemic injury of rat cerebral infarction by Qingkailing Injection，and to explore the possible mechanism of Qingkailing Injection in the treatment of acute cerebral ischemia.Methods:A rat model of permanent middle cerebral artery infarction (MCAO) was prepared by suture method and randomly divided into a sham operation group，a model group，and a Qingkailing Injection treatment group.TTC staining was used to observe the changes in infarct volume of rat brain tissue before and after treatment.Protein chip，ELISA and immunohistochemistry were used to detect the expression level of FKN in cerebrospinal fluid，peripheral serum and brain tissue.Results:TTC staining of brain tissue showed that there were obvious infarcts in the model group，and the infarct volume in the Qingkailing treatment group was significantly reduced.Compared with the model group，the Qingkailing treatment group significantly down-regulated the FKN of the diseased local brain tissue (P<0.05)，and significantly increased the FKN in the serum (P<0.05).It was observed that it could up-regulate the cerebrospinal fluid and the whole brain FKN.But the difference was not statistically significant (P>0.05).Conclusion:Qingkailing Injection can reduce the volume of cerebral infarction and reduce acute cerebral ischemic injury.The mechanism may be related to the regulation of FKN expression. |
