Objective:To explore the therapeutic effect of intra-aortic balloon counterpulsation (IABP)on acute my-ocardial infarction (AMI)complicated pump failure.Methods:Clinical data of 82 AMI patients complicated pump failure,which received emergency percutaneous coronary intervention (PCI)in our hospital from Jan 2010 to Oct 2013,were retrospectively analyzed.The patients were divided into IABP group (n=42,received PCI with auxiliary IABP)and routine PCI group (n=40,only received routine PCI therapy).Success rate of treatment,mortality,he-modynamic conditions [systolic blood pressure (SBP),diastolic blood pressure (DBP)and heart rate (HR)]stable to PCI time,length of hospital stay and complications were compared between two groups.Results:Compared with routine PCI group after treatment,there were significant rise in blood pressure [SBP: (80.3± 16.2)mmHg vs. (88.4±12.5)mmHg,DBP:(55.4±10.2)mmHg vs.(60.0±10.5)mmHg]and urine volume [(30.2±8.3)ml/h vs.(40.3±9.4)ml/h],and significant reduction in HR [(92.4±26.1)times/min vs.(80.5±18.5)times/min] in IABP group,P <0.05~<0.01;there was significant increase in success rate (72.5% vs.83.3%),and signifi-cant decrease in mortality rate (27.5% vs.16.7%),time stable to PCI for hemodynamical condition [(10.1±8.1) h vs.(5.0±2.5)h]and length of hospital stay [(18.4±6.2)d vs.(13.5±4.2)d]in IABP group,P <0.05 all;incidence rate of complications was no significant difference between groups (P >0.05).Conclusion:IABP adjuvant treatment helps to raise success rate of PCI,improve hemodynamic condition and increase urine volume,shorten length of hospital stay in patients with AMI complicated pump failure.

Vinorelbine（NVB）is a semisynthetic vinca alkaloid and can play an anti-tumor role by inhibiting the synthesis of tubulin. Its oral preparation has been used in the treatment of a variety of tumors as its convenience and good clinical response. The blood concentration of NVB is closely related to its curative effect and toxicity. Small variations in blood concentration may reduce the curative effect and even produce serious toxicity. There are some risks in the clinical drug use due to limited clinical data and effective pharmacodynamic monitoring methods. By reviewing the relevant literature at home and abroad ，this paper summarizes the research progress of in vivo pharmacokinetics and toxicity of NVB ，fully understands the pharmacokinetic characteristics and influencing factors of NVB ，the influencing factors of toxicity ，and the application status of pharmacokinetics in the adjustment of administration scheme ，so as to provide reference for its clinical rational use.
