When the ventricular rate was controlled to below 90 bpm, the patients would almost complain of no discomfort. No severe side-effect was observed in each group.Conclusion Amiodarone and cedilanid may be the proper drugs for the treatment of paroxysmal atrial fibrillation in the elderly.The above antiarrhythmics in each therapeutic group were relatively safe and effective.展开更多

Methods The online databases PubMed and EMBASE were searched for relevant studies. STATA software （version 12.0） was used to perform the meta-analysis and meta-regression. Results Fifteen randomized controlled trials including 2249 patients with AF were identified. The pooled results showed that catheter ablation was associated with a 52% reduction in the risk of AF recurrence compared with ADT [risk ratio （RR） = 0.48, 95% confidence interval （CI）： 0.40-0.57, I2 = 70.7%）. Subgroup analyses showed that catheter ablation exhibited less efficacy in studies after 2011 compared to studies before 2011 （RR = 0.61, 95% CI： 0.54-0.68, I2 = 9.3% and RR = 0.34, 95% CI： 0.24-0.47, I2 = 69.9%, respectively）, and the safety outcome showed a 1.08-fold higher incidence of adverse events （14.2% vs. 7.3%; RR = 1.08, 95% CI： 1.04-1.13） in studies after 2011. Conclusions Catheter ablation appears to be superior to ADT for rhythm control. However, less efficacy and a higher rate of adverse events were observed in studies after 2011 compared to studies before 2011.展开更多

For this purpose, multifunctional probes capable of both imaging and curing are needed. In this work, we synthesize water-soluble silicon quantum dots（Si QDs） smaller than 5 nm. Such Si QDs are used for delivering the hydrophobic drug phthalocyanine（Pc）. The as-prepared Si/Pc nanocomposite particles show efficient transmembrane delivery into cells and feasible biocompatibility. Moreover, these composite particles emit dualchannel fluorescence signals even after cellular internalization and demonstrate robust photostability in the Si channel.More interestingly, the Si/Pc composite particles show efficient photodynamic therapy effects against tumors both in vitro and in vivo.展开更多

Methods: Clinical data of 2 375 cases of TACE for 832 patients with middle-stage or advanced hepatocellular carcinoma from January 1994 to December 2002 were analyzed. Results: There were 7 cases of serious complications, one of which was liver carcinoma rupture and another was acute renal failure. Totally there were 4 cases of paraplegia and one case of conduit knotted. Conclusion: Deadly complications may happen after TACE and it needs close surveillance and management in time.展开更多
