ObjectiveTo evaluate the safety and efficacy of tirofiba in the treatment of patients with acute ST-elevation myocardial infarction (STEMI) undergoing emergency percutaneous coronary intervention (PCI). MethodsA total of 158 patients with acute STEMI were randomly divided into tirofiban group 1 (59 cases, received tirofiban before PCI), tirofiban group 2 (56 cases, received tirofiban when PCI) and control group(43 cases, only received PCI). The coronary reperfusion flow(TIMI grade) of infarct related artery (IRA) after PCI, the resolution of the sum of ST segment elevation(sum STR) at 90 min after the procedure, the changes of myocardial enzyme at 6 h and 12 h afterwards, the left ventricular ejection fraction (LVEF) 1 week later, the major adverse cardiac events(MACE) within 30 d, bleeding and thrombocytopenia complications were analyzed and compared among the three groups. ResultsTIMI reperfusion grades in tirofiban group 1[98.3％(58/59 )]and tirofiban group 2[92.9％(52/56)]were higher than those in control group[60.5％(26/43)](P ＜0.05). The resolution of sum STR at 90 min after PCI in tirofiban group 1 [(89.3 ± 6.9)％]and tirofiban group 2[(82.4 + 7.3)％]was higher than that in control group[(65.6 +8.1 )％](P＜ 0.01 ),and there was significant difference between tirofiban group I and tirofiban group 2 (P＜0.05 ). The occurrence of MACE within 30 d was lower in tirofiban group 1 and tirofiban group 2 than that in control group (P＜ 0.05). The level of CK-MB at 6 h and 12 h afterwards was lower in tirofiban group 1 than that in tirofiban group 2,and tirofiban group 2 was lower than control group (P＜ 0.05). LVEF 1 week later in tirofiban group 1[(56.2 + 6.4)％]was higher than that in tirofiban group 2[(51.1 + 4.9)％]and control group[(49.8 + 5.7)％](P ＜ 0.05),but there was no significant difference between tirofiban group 2 and control group (P ＞ 0.05). Although bleeding incidence in tirofiban group 1 and tirofiban group 2 was higher than that in control group, no severe bleeding and thrombocytopenia was observed. Conclusion Tirofiban can safely and effectively reduce the incidence of the ischemic events in the patients with acute STEM1 during preoperative of emergency PCI.

Objective To explore the efficacy of two treatment methods for thoracic tuberculosis.Methods According to the different surgical methods,61 patients with thoracic tuberculosis were randomly divided into A group (31 cases) and B group (30 cases).A group was treated with simple thoracic tuberculosis soft tissue lesions removed,and B group was treated with focus removal + rib resection + muscle flap packing.The operation time,pain time,extubation time,hospital stay,wound fluid,cure rate and recurrence rate were compared between the two groups.Results The operation time,pain time,hospital stay time of A group were shorter than those of B group [(35.0 ± 11.0)minvs.(50.0 ±9.5)min,(1.8±1.3)d vs.(4.2 ±2.4)d,(12.5 ±3.4)d vs.(18.8 ±5.7)d],the differences were statistically significant (t =6.257,4.275,5.334,all P ＜ 0.05).There were no statistically significant differences in the extubation time,wound effusion,cure rate and recurrence rate between the two groups [(5.8 ± 3.1) d vs.(5.5 ± 2.8) d,2 cases vs.1 case,100.0％ vs.100.0％,6.4％ vs.3.3％,t =8.691,x2 =9.867,13.674,15.871,all P ＞ 0.05].Conclusion Analysis of the specific situation should be individualized on the chest wall tuberculosis,in the case of rib destruction,the focus should be removed + rib resection + muscle flap packing,if there is no rib destruction,simple chest wall tuberculosis soft tissue lesions removal is more safe,because it is less traumatic for patients.
