Objective To investigate clinical evaluation of Kudiezi injection in treatment of acute cerebral infarction and its effects on serum vascular endothelial growth factor(VEGF), S-100β, matrix metalloproteinases(MMP)-9 levels.Methods 98 patients of acute cerebral infarction who received therapy from October 2014 to October 2016 in our hospital were selected.Those patients were randomly divided into the observation group and the control group with 48 cases in each group.The control group was treated with routine treatment, while the observation group was treated with Kudiezi injection.After treatment of 14 days, the clinical curative effect, serum VEGF, S-100β, MMP-9, National institutes of health stroke scale (NIHSS) and Barthel index were compared.Results After treatment, the total effective rate in the observation group 87.75%(43/49) was significantly higher than that of the control group 65.31%( 32/49 ) , the difference was statistically significant ( P<0.05 ) , the level of VEGF in the observation group was significantly higher than that of the control group, and the S-100βand MMP-9 were significantly lower than that of the control group, the difference was statistically significant (P<0.05), the NIHSS score in the observation group was significantly lower than that of the control group, the difference was statistically significant (P<0.05), the Barthel index in the observation group was significantly higher than that of the control group, the difference was statistically significant (P<0.05).Conclusion Kudiezi injection is well for acute cerebral infarction, which can effectively improve the serum levels of VEGF, S-100β, MMP-9, and can improve the therapeutic effect, promote the recovery of neurological function and improve the quality of life.

Objective To investigate the relationship between aquaporin-4 (AQP4) expression level inbrain and dynamic change of brain edema in rats after cardiopulmonary resuscitation (CPR), and to evaluate the in-tervention effects of Edaravone. Method Totally 72 Sprague-Dawley male rats were randomly divided into fourgroups:normal group (n = 6, group A) ,shame-operated group ( n = 6, group B), CPR group including 1 hour,6 hours, 12 hours, 24 hours, and 72 hours after ROSC (5 sub-groups, n = 6for each,group C) ,edaravone-treat-ed group with the same time points as CPR groups(5 sub-groups, n = 6for each,group D). Asphyxia cardiac ar-rest with CPR model was used in group C and group D. Edaravone at a dose of 3.0 mg/kg was given intravenouslyand the same dose of edaravone was administered subcutaneously to the rats of group D after CPR. Anaesthosia,vascular cannulation and endotracheal intubation were pedormed in rats without asphyxia and CPR in group B. Ateach interval, the brain water content was calculated. The AQP4 expression level in brain tissue was determinedusing immunohistocbemical staining. Neurodeficit scores were assessed and pathological change was observed, Re-sults The brain water content in rats of group C increased obviously along with the prolongation of time followingROSC,and reached its peak at ROSC 24h,which was much higher than that of group B (P<0.01). Meanwhile,AQP4 expression in brain had a trend towards increasing and the integral optical density(iOD) and coloratian arearatio(△S) in group C were significantly increased compared with group B ( P<0.01). The trend of changes wasnearly the same as that of the brain water content. The correlation analysis demonstrated that AQP4 expression levelsuch as iOD (r=0.858, P < 0.01 ) and △S ( r = 0.870, P < 0.01 ) were correlated with the brain watercontents apparently. Compared with group C, the brain water content was decreased obviously (P<0.05), iODand △S was down-regulated at the same lime (P<0.01) in group D. The neurodeficit scores increased (P <0.05) and pathological damage was dramatieaUy ameliorated. Conclusions AQP4 expression increased greatly inbrain after CPR and the relationship between AQP4 and brain edema was positively correlated. AQP4 may play arole in the formation of brain edema following CPR. Edaravone could attenuated brain edema after CPR in rats byway of inhibiting the expression of AQP4. It had neuroprotective effect.
