Background and Objective: Factors that are associated with the recurrence after radioactive iodine ablation therapy have not been identified yet. The aim of this study is to elucidate the factors that are related to the recurrence after thyroid surgery of the thyroid papillary cancer followed by radioactive iodine ablation therapy. Patients and Methods: Fifty four cases who had underwent thyroid cancer surgery and postoperative radioactive iodine ablation therapy were included in this study. Mean followup duration was 7 years. There were 41 women and 13 men. Data analysis was done retrospectively with medical record review. Chi-square test and Fisher's exact test was used for the statistical analysis. Results: Age over 40, capsular invasion, and loca invasion were the factors that were associated with the high rate of recurrence. But sex, size of the tumor, multiplicity and extent of the surgery were not related to the recurrence. Conclusion: Without the curative resection of the tumor, radioactive iodine ablation therapy cannot lower the recurrence rate. So aggressive resection of the thyroid papillary cancer is important.The more data accumulated and the longer the followup, the easier we can reveal the recurrence-related factors of postoperative radioactive ablation therapy.

<P>Abstract</P><P><B><I>Background/Aims:</I></B> Atrial fibrillation (AF) often coexists with acute myocardial infarction (AMI), and chronic kidney disease (CKD) is a major risk for AMI. However, the combined impact of CKD and AF on the mortality and morbidity in AMI population has not been determined. <B><I>Methods:</I></B> Between January 2004 and December 2009, a total of 4,738 AMI patients were enrolled prospectively. Patients were divided into four groups according to the combined status of CKD and AF. The primary endpoint was a combination of 5-year major adverse cardiac and cerebrovascular events (MACCE). <B><I>Results:</I></B> The prevalence of AF was significantly higher in CKD patients than in non-CKD patients (6.76 vs. 3.31%, p < 0.001). The highest cumulative event rate of MACCE and death was observed in patients with both CKD and AF (68.5 and 64.0%), respectively. In multivariable analyses, compared with patients with neither AF nor CKD, hazard ratios (HR) for composite of MACCE were 1.66 (95% CI, 1.14-2.41), 1.24 (95% CI, 1.06-1.46), and 2.10 (95% CI, 1.42-3.13) for patients with AF only, those with CKD only, and those with both CKD and AF, respectively (p for interaction = 0.935). Patients with both CKD and AF had a greatest risk for all-cause mortality (HR 2.54; 95% CI, 1.60-4.53), and the significant synergistic interaction was observed between CKD and AF (p for interaction = 0.015). <B><I>Conclusion:</I></B> The combined effect of AF and CKD on the risk of MACCE after an AMI is stronger than any separate condition, and it confers a synergistic effect on the all-cause mortality risk.</P><P>© 2014 S.

<P>Manic episodes are one of the major diagnostic symptoms in a spectrum of neuropsychiatric disorders that include schizophrenia, obsessive-compulsive disorder and bipolar disorder (BD). Despite a possible association between BD and the gene encoding phospholipase C gamma 1 (PLCG1), its etiological basis remains unclear. Here, we report that mice lacking phospholipase C gamma 1 (PLC gamma 1) in the forebrain (Plcg1(f/f); CaMKII) exhibit hyperactivity, decreased anxiety-like behavior, reduced depressive-related behavior, hyperhedonia, hyperphagia, impaired learning and memory and exaggerated startle responses. Inhibitory transmission in hippocampal pyramidal neurons and striatal dopamine receptor D1-expressing neurons of Plcg1-deficient mice was significantly reduced. The decrease in inhibitory transmission is likely due to a reduced number of gamma-aminobutyric acid (GABA)-ergic boutons, which may result from impaired localization and/or stabilization of postsynaptic CaMKII (Ca2+/calmodulin-dependent protein kinase II) at inhibitory synapses. Moreover, mutant mice display impaired brain-derived neurotrophic factor-tropomyosin receptor kinase B-dependent synaptic plasticity in the hippocampus, which could account for deficits of spatial memory. Lithium and valproate, the drugs presently used to treat mania associated with BD, rescued the hyperactive phenotypes of Plcg1(f/f); CaMKII mice. These findings provide evidence that PLC gamma 1 is critical for synaptic function and plasticity and that the loss of PLC gamma 1 from the forebrain results in manic-like behavior.</P>
