To explore the curative effects of Western medicine combined with traditional Chinese medicine on cerebral infarction and its influence on the establishment of collateral circulation in patients with cerebral infarction.Methods:A total of 128 patients with cerebral infarction admitted to Beijing Second Hospital from June 2017 to January 2019 were selected as research objects,and they were divided into an observation group and a control group according to the random number table method,with 64 cases in each group.Patients in the control group were treated with routine western medicine (edaravone injection),while patients in the observation group were treated with traditional Chinese medicine (Shuxuetong injection) on the basis of the control group.The therapeutic effect,neurological deficit (NIHSS score),daily living ability (Bathel score),blood lipid,hemorheology and cerebral blood flow in ischemic area before and after treatment were compared between the 2 groups.Results:The total effective rate of the observation group was 90.6% (58/64),higher than 75% (48/64) of the control group.There was significant difference between 2 groups (P<0.05); before treatment,there was no significant difference in NIHSS score,Bathel score,blood lipid level,hemorheological index and cerebral blood flow in ischemic area between the 2 groups (P>0.05); after treatment,the NIHSS score of the observation group was lower than that of the control group,and the Bathel score was significantly higher than that of the control group (P<0.05).After treatment,the blood lipid level and hemorheological indexes in the observation group were better than those in the control group,and the cerebral blood flow in the ischemic area in the observation group was significantly higher than that of the control group (P<0.05).Conclusion:Integrated traditional Chinese and Western medicine can effectively improve the therapeutic effects of cerebral infarction patients,help to improve the neurological function and daily living ability of patients,improve blood lipid and hemorheological indicators,and is conducive to the establishment of collateral circulation.
