Expression and function of c-Myc in tumor / 国际肿瘤学杂志

The proto oncogene c-Myc is expressed in many kinds of organs, and its dysfunction is closely related to the occurrence and prognosis of lymphoma, prostatic cancer, breast cancer and pancreatic cancer.With a large number of studies focus on the expression and function of c-Myc in tumor, the treatment of tumor by targeting c-Myc has made a wealth of progress.

Clinical analysis of 28 cases of non benign neonatal arrhythmias / 临床儿科杂志

Objective To discuss the etiology, clinical features and prognosis of non benign neonatal arrhythmias. Method Clinical data of 27 cases of non benign neonatal arrhythmias diagnosed from January 2005 to January 2010 were retrospectively analyzed. Results Among 27 neonats, there were 15 male and 12 female. Fourteen cases were early neonatal and 13 were late neonatal. Gestational age was less than 32 weeks in 6 cases, and more than 32 weeks in 21 cases. In 19 cases with tachyarrhythmia, 14 cases were induced by respiratory infection. The causes of 8 newborns with bradycardia arrhythmia were congenital heart disease (3 cases), electrolyte disturbance (2 cases), severe asphyxia with sepsis (2 cases), and severe asphyxia (1 case). The onset age and gestational age were lower in cases with bradycardia arrhythma that those in cases with tachyarrhythmia (P<0.005). The cure rate and effective rate of tachyarrhythmia was 89.5%and 100%, of bradycardia arrhythmia was 0%and 12.5%, respectively, and the differences were signiifcant (P<0.005). Conclusion Clinical characteristics, pathogenesis and prognosis were different between tachyarrhythmia and bradycardia arrhythmia in neonates.
