ABSTRACT
Objective To investigate the effects of rapid response system of chest pain on the short-term and long-term prognosis of patients with acute ST segment elevation myocardial infarction (STEMI).Methods Referring to the international association of chest pain centers,the chest pain center was established in this hospital,and the corresponding management system and treatment process were worked out.A total of 374 acute STEMI patients who were recruited as the observation group were admitted to this hospital after the establishment of the chest pain center (December 2014 to June 2016),and 250 STEMI patients admitted before the establishment of the chest pain center (January 2012 to December 2012) were recruited as control group.Patients in observation group were treated in the chest pain center,and those in control groupreceived conventional treatment.The general situation,basic diseases,the finishing time of the first electrocardiogram(ECG),the time of door-to balloon expansion(D2B),the time of hospital stay,the average hospitalization expenses,in-hospital cardiac events and in-6-month cardiac events were compared between the two groups.All patients were followed up for 1 years,left ventricular ejection fraction(LVEF),left ventricular end diastolic diameter (LVEDD),left ventricular aneurysm,B type natriuretic peptide (pro-BNP),serum creatinine (Scr),C-reactive protein (CRP) levels and adverse cardiac events (heart failure,death,readmission rate etc.)were compared between two groups.Results Compared with the control group,the average completion time of the first electrocardiogram in the observation group was shortened (P=0.001),the time of entry balloon dilatation,the time of hospital stay,the average hospitalization expenses were less than that of the control group (P＜0.05),the adverse cardiac events (hospital death and heart failure) were lower in the observation group than in the control group (P＜0.05).After 6 months of follow-up,LVEF was significantly higher in the observation group than in the control group (P＜0.05).the levels of LVEDD,pro-BNP,CRP and adverse cardiac events in the observation group were significantly lower than those in the control group (P＜0.05),there was no significant difference in the formation rate of ventricular aneurysm and Scr between the observation group and the control group (P＞0.05).After 1 year of follow-up,LVEF was still higher in the observation group than in the control group (P＜0.05).The incidence of LVEDD,pro-BNP,CREA,CRP,left ventricular aneurysm formation rate,the incidence of adverse cardiac events were lower in the observation group than in the control group (P＜0.05).Conclusion The establishment of rapid response system of chest pain treatment not only effectively shortenthe treatment time of STEMI patients,improve the treatment efficiency,shorten the hospital stay,reduce the cost of hospitalization,but also improve the quality of life and disease prognosis.
ABSTRACT
Objective To investigate the effect of propofol on rat′s limb ischemia reperfusion injury .Methods Sixty healthy SD rats were randomly divided into sham operate group ,ischemia-reperfusion group and propofol group (n= 20) ,each group was divided into 4 subgroups according to the different reperfusion time .To copy the right lower limb ischemia reperfusion model ,5 min before reperfusion ,use propofol injection (50 mg/kg ,intraperitoneal inject) ,various subjects in the corresponding time points (3 ,6 , 9 ,12 h) were sacrificed .TNF-α ,NF-κB of blood and MDA ,SOD of Skeletal muscle were measured ,calculate muscle wet dry weight ratio .Results Compared with ischemia reperfusion group ,propofol could significantly reduce expression of TNF-alpha ,NF-κB lev-els in serum (P< 0 .05) ,inhibit the increase of the MDA level and decrease of the SOD level in muscle (P< 0 .05) ,also reduce the extent of skeletal muscle cell edema(P< 0 .05) .Conclusion Propofol can attenuate limb ischemia reperfusion injury by inhibiting inflammation response and reducing the oxygen free radicals′ damage .
ABSTRACT
Objective to investigate the effect of berberine on the expression of AQP4 and neuronal injury after focal cerebral ischemia in diabetic rats. Methods Male SD rats were randomly divided into four groups:control(sham surgery),middle cerebral artery occlusion and reperfusion (MCAO/R),MCAO/R treated with vehicle(DMSO),MCAO/R treated with berberine. the transient focal ischemia/reperfusion was induced by in-troducing silicone-coated monofilament nylon suture from the right external carotid artery into the origin of the middle cerebral artery,which was re-moved after 60 min. In group treated with berberine,the rats were injected with berberine before and after suffered from cerebral ischemia. Similarly, in group vehicle,the animals received DMSO vehicle at the same time. the score of neurological behavior was evaluated 24 h after reperfusion. Mean-while,the rats were sacrificed for Nissl staining. to estimate cerebral edema,the wet-dry ratio was measured. the expression of AQP4 in the border of the infarct region in different groups was observed by Western blot. Results Compared with the model group,berberine improved neurological deficits(P < 0.05). Berberine treatment inhibited the neuronal deformation shown by Nissl staining(P < 0.05). Berberine significantly decreased the wet-dry ratio and reduced the expression of AQP4(P < 0.05). Conclusion these results suggested that berberine could induce neuroprotection against ischemic injury by inhibiting the expression of AQP4 in diabetic rats.
