There are some major changes win the revised 2016 WHO Classification of Lymphoid Neoplasms.Based on the clinicopathological changes and genetic/molecular findings in the past years,the new classification clarified the diagnosis and clinical management of some very early stages of lymphoproliferative disorders,refined the diagnostic criteria for some lymphoid neoplasms,and further emphasized the significance of genetic/molecular studies in the diagnosis and clinical treatment of lymphomas.A small number of new provisional entities were added to the 2016 edition.
2.Predictive value of epicardial adipose tissue thickness for the recurrence of atrial fibrillation after concomitant valve replacement and bipolar radiofrequency ablation
Clinical Medicine of China 2016;32(5):447-450
Objective To investigate the predictive value of epicardial adipose tissue(EAT) thickness for the recurrence of atrial fibrillation (RAF) after concomitant valve replacement and bipolar radiofrequency ablation.Methods From January 2012 to May 2014,156 patients with permanent atrial fibrillation and organic valvular diseases underwent concomitant valve replacement and successful bipolar radiofrequency ablation in the First People's Hospital of Shangqiu.After 1 year of follow-up,the recurrence of AF was analyzed and the correlation factors were analyzed statistically.Results All patients completed a regular follow-up.During a 12-month follow-up period,RAF was observed in 39 patients (25.0%).Echocardiography-derived regional EAT thickness was significantly greater in RAF patients than that in non-RAF patients((6.9±0.6) mm vs.(5.5±0.7) mm,t=4.649,P<0.05).The EAT thickness strongly correlated with patients age,body mass index,Ratio of left atrial diameter,mitral diastolic blood flow velocity and early diastolic velocity of mitral annulus,low density lipoprotein-cholesterol and thyroglobulin (r =0.62,0.57,0.68,0.59,0.73,0.76;P < 0.05).Cox multivariable analysis showed that,duration of AF history (95%CI:1.01-1.15,P =0.040),left atrial diameter (95%CI:1.07-1.24,P =0.021) and EAT thickness (95%CI:1.05-1.79,P =0.009) were independent predictors of RAF.Conclusion Echocardiography-derived regional EAT thickness combined with left atrial diameter may serve as effective parameters in identifying patients at the highest risk for RAF.

Tumor vaccine is one of the most promising therapeutic strategies in tumor immunotherapy. It promotes the antigen presentation process by delivering tumor antigen and then activates the anti-tumor immune response. As a new class of vaccines, messenger RNA (mRNA) vaccines can activate the immune system to achieve the purpose of immunotherapy by delivering the mRNA sequence of a specific antigen into the body and expressing the corresponding antigen protein. Compared with traditional vaccines, mRNA vaccines have the advantages of a short production cycle, high effectiveness, and strong immunogenicity. In recent years, the application of mRNA vaccines in tumor immunotherapy has attracted widespread attention, but the instability and low delivery efficiency of mRNA limit its application. Nano delivery system can effectively solve the problem of mRNA vaccine delivery, greatly promote the research process and clinical application of mRNA tumor vaccines, and has become a hot spot in the research of mRNA vaccines. In this review, we introduced the mRNA tumor vaccines, focusing on the application of nano delivery system in mRNA tumor vaccines, in order to provide new ideas and new methods for the efficient delivery of mRNA tumor vaccines and tumor immunotherapy.
