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). No-reflow incidence in group B was lower while the proportion of blood flow arriving TIMI III grade was higher than that in group A in early phase (P < 0.05). The incidence of adverse events in 30 days was decreased in group B when compared with group A ,but the difference wasn't statistically significant (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.

OBJECTIVETo evaluate effect of amygdalin on expression of four biomarkers in the animal model of pulmonary fibrosis induced by bleomycin.

METHODSRats were given one dose (5 mg/kg) of bleomycin in bleomycin-treated groups, amygdalin-treated groups and saline in controls by intratracheal instillation exposed surgically. The amygdalin-treated groups rats were treated with intraperitoneal injection of amygdalin (15 mg x kg(-1) x day(-1)). The rats were sacrificed 7, 14 and 28 days after bleomycin administration. Polarized light microscopy and Image-Pro Plus detected I and III collagen expressed in Paraffin-embedded lung sections stained with Sirius red. Surface-enhanced laser desorption-ionization time-of-flight mass spectrometry (SELDI-TOF MS) with weak cationic proteinchip (CM10) detected differentially expressed proteins in the pooled serum samples of all groups.

RESULTSConsistent fibrotic responses were found in all bleomycin and amygdalin-tread groups. On the 7th, 14th and 28th day after bleomycin or saline instillation, four differentially expressed proteins were detected in the pooled serum of all groups rats, consisting of 4 proteins with mass/charge ratio of 3530.7, 7043.5, 8332.6 and 9068.0, respectively. Compared with control groups, protein peaks intensity ratio with mass/charge ratio of 3530.7 on 7, 28 d and 7043.5, 8332.6 and 9068.0 on 7, 14 and 28 d was > 2 in bleomycin-treated groups. Compared with amygdalin-treated groups, protein peaks intensity with mass/charge ratio of 3530.7 at 7, 14, 28 d had no change almost, but protein peaks intensity ratio with mass/charge ratio of 7043.5 at 7 d, 8332.6 on 28 d and 9068.0 on 14 d was > 2 in bleomycin-tread groups. All the four protein peaks intensity had no change almost at other point.

CONCLUSIONAmygdalin may reduce the bleomycin-induced increase of differentially expressed protein peak intensities in rat serum.
