Polymorphisms in ERCC1 and XPF gene and response to chemotherapy and overall survival of non-small cell lung cancer.

We conducted a perspective study to assess the association between ERCC1 and XPF polymorphisms and response to chemotherapy and clinical outcome of NSCLC receiving chemotherapy. Between May 2009 and May 2011, a prospective study was conducted on 240 NSCLC cases. Genotypes of ERCC1 (rs11615, rs3212986 and rs2298881) and XPF (rs2276465 and rs6498486) were performed by Polymerase Chain Reaction Restriction Fragment Length Polymorphism (PCR-RFLP) assay.

[The effect of ventricular fibrillation time and NYHA classification on defibrillation in intensive care unit patients].

Objective: To investigate whether the sequence of defibrillation (DF) and cardiopulmonary resuscitation (CPR), duration of ventricular fibrillation (VF), and New York Heart Association (NYHA) classification would affect DF result in intensive care unit.

Methods: Ninety-three cases needing instantaneous DF were divided into three groups according to VF lasting time: <4 minute group (n=53), 4 - 8 minute group (n=24), >8 minute group (n=16), and each group was randomly divided into two sub-groups according to time sequence: the prior DF group or the prior CPR for five cycles followed by DF group (prior CPR group). The effect of VF time, the sequence of DF and CPR, and NYHA classification on success rate of DF were observed.
