ABSTRACT
Objective To investigate the effect of Shenxiong glucose injection on platelet reactivity during aspirin treatment in patients with acute ischemic stroke.Methods A total of 263 patients with acute ischemic stroke admitted to 12 hospitals from January 2014 to December 2016 were enrolled prospectively.They were randomly divided into aspirin group and aspirin + Shenxiong glucose injection group.The changes of platelet maximum aggregation rate induced by 4 platelet aggregating agents (arachidonic acid,adenosine diphosphate,collagen and platelet activating factor) were detected before and after the treatment.Results There were no significant differences in the demographic data and baseline clinical characteristics between the aspirin group (n =132) and the Shenxiong glucose injection + aspirin group (n =131).At baseline,the maximum aggregation rate of platelet induced by arachidonic acid and platelet activating factor in Shenxiong glucose injection + aspirin group was significantly higher than that in the aspirin group (all P ＜0.05).On the 6th day after treatment,the maximum aggregation rate of platelets induced by the 4 aggregating agents in the Shenxiong glucose injection + aspirin group was significantly lower than that in the aspirin group (all P ＜ 0.001).Conclusion Shenxiong glucose injection had a significant inhibitory effect on platelet reactivity during aspkin treatment in patients with acute ischemic stroke.
ABSTRACT
Objective To investigate the correlation between the infarction location and progressive motor deficits (PMD) occurrence.Methods The patients with middle cerebral artery(MCA) infarction within 24 h of onset without thrombolytic therapy were included.The National Institutes of Health Stroke Scale(NIHSS) motor item score increase ≥2 points of the base line within 7 d after stroke onset served as the PMD diagnostic criteria.The differences in clinical and laboratory data,and infarction location were compared between the PMD group and non-PMD group.The multivariate Logistic regression analysis predicted the risk factors of PMD occurrence.Results A total 121 patients with MCA acute cerebral infarction were included in the study and divided into the PMD group (45 cases) and non-PMD group (76 cases).The internal watershed infarction occurrencerate in the PMD group was higher than that in the non-PMD group (26.7 ％ vs.5.3％,p=0.001).The occurrence rate of penetrating arterial infarction (PAI) had no statistical difference between the PMD group and non-PMD group(42.2％ vs.35.5％,P=0.463).PAI was further divided into perforating branch atheromatous disease (BAD) and lipohyalinitic degeneration (LD).The occurrence rate of BAD in the PMD group was significantly higher than that in the non-PMD group (28.9％ vs.9.2％,P=0.005).The stepwise Logistic regression analysis indicated that watershed infarction [odds ratio (OR):9.750,95 ％ confidence interval(CI):2.828-33.612,P=0.000] and BAD lesion (OR:6.036,95 ％ CI:2.119-17.190,P =0.001) were the independent risk factors contributing to PMD.Conclusion Internal watershed infarction and BAD lesion may predict the PMD occurrence.The infarct location is conducive to find the high risk population of cerebral infarction progress.
ABSTRACT
Objective To investigate the detection of central venous oxygen saturation ( ScvO2 ) whether can be alternative mixed venous oxygen saturation ( SvO2 ) in elderly patients with acute left ventricular failure.Methods 42 elderly patients with acute heart failure were detected by central venous oxygen saturation and mixed venous oxy-gen saturation before the treatment and 1h,2h,4h after treatment.Then the parameters index changes were analyzed according to the prognosis.Results Whatever the prognosis of the patients were,the trend of ScvO2 and SvO2 was the same.Before the treatment,the blood oxygen saturation detected by the ScvO2 with patients was no statistical differ-ence with the ScvO2(t=0.867,P>0.05),and after treatment of 4h the change trend detected of both has also the consistency,no statistical difference (t=0.681,P>0.05) The correlation coefficient r=0.998,and the relationship between ScvO2 and SvO2 confirmed the same clinical significance.Conclusion Considering the factors of trauma, complications,costs and so on,ScvO2 can be used to replace SvO2 in elderly patients with acute left heart failure.
