0 05) Conclusion Most of the CHQ tested (11/15) showed in vitro antiplatelet aggregation activities on human platelet Among them the effect of Fructus Aurantii Immaturus, Pericarpium Citri Reticuatae Viride and Pericarpium Citri Reticulatae were superior or equal to Aspirin

Objective To analyze the relationship between the posterior circulation cerebral infarction and posterior embryonic cerebral artery,and to explore the possibility of posterior embryonic cerebral artery to be predictive indicator for the occurrence and development of the posterior circulation infarction.Methods A total of 2341 posterior circulation cerebral infarction patients in our hospital were recruited,and its location was confirmed in infarction circulation blood supply range and existence condition of posterior embryonic cerebral artery was explored by head MRI and DWI.The correlation between posterior embryonic cerebral artery and posterior circulation cerebral infarction,arteriosclerosis.Results Among the 2341 patients,there were 1012(41.63％) patients with posterior circulation infarction,including 314 cases with left posterior circulation infarction,295 cases with right posterior circulation infarction,403 cases with bilateral posterior circulation infarction.There were 578 (23.78％) patients with embryonic posterior cerebral artery,including 179 cases with left posterior cerebral artery,257 cases with right posterior cerebral artery,and 142 cases with bilateral posterior cerebral artery.There were 1193 (49.1％) patients with cerebral arteriosclerosis.The incidences of cerebral arteriosclerosis and posterior circulation cerebral infarction showed significant difference in the embryo posterior cerebral artery and non-embryo posterior cerebral artery patients (P ＜ 0.05),but no significant difference in posterior embryonic cerebral artery patients with different locations (P ＞ 0.05).Conclusion Embryonic posterior cerebral artery has a significant correlation with posterior circulation cerebral infarction,and can significantly increase the incidence of posterior circulation cerebral infarction.
