RESUMO
Objective To evaluate the effect of tirofiban injection in coronary artery occlusion by suction catheter on the opening time of the coronary artery occlusion , the improvement of the blood flow and the incidence of adverse events in 30 days. Methods A total of 97 patients with acute myocardial infarction in recent 4 years were included , whose culprit vessels were subtotal occlusion or total occlusion by angiography and were randomly divided into thrombus aspiration group (group A) and tirofiban injection in occlusion and thrombus aspiration group (group B). The opening time of the coronary artery, the improvement of the blood flow and the incidence of adverse events in 30 days were compared between two groups. Results The opening time of the coronary artery occlusion in group A was shortened when compared with group B but the blood flow arriving TIMI III grade in group B was shorter (P 0.05). Conclusion Direct tirofiban injection in coronary artery occlusion could effectively shorten the opening time of the coronary artery occlusion reduce no-reflow incidence , and improve coronary perfusion but could not decrease the incidence of adverse cardiovascular events in 30 days.
RESUMO
[Objective]To introduce the traditional application and modern research of Radix Gentianae and to provide reference to developing and researching Radix Gentianae.[Methods]We analyzed the number of representative literature home and abroad and summed them up.[Result]Studies about traditional Chinese medicinal application,traditional Chinese medicinal resources,chemical composition,pharmacodynamics,pharmaceutical preparation and clinic of Radix Gentianae have been generalized.[Conclusion]At present traditional Chinese medicinal resources,chemical composition,pharmacodynamics and clinic of Radix Gentianae have been studied a lot,but studies about quality evaluation,the reason of droping out the market and the dynamic of ecosystem of G.manshurica var.yanchowensis have been relatively carried out a little.And all of them deserve research.
