Purpose:To determine the effi cacy and safety of transarterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC) and main portal vein (MPV) invasion. Materials and Methods:This study was approved by the institutional review board, and the requirement to obtain informed consent was waived. The authors retrospectively assessed the electronic medical records of patients in whom HCC with MPV invasion was newly diagnosed from January 2004 to December 2007 at a single tertiary medical center. Patients with decompensated hepatic function were excluded. Outcomes of patients treated with TACE were compared with those of patients given supportive care according to Child-Pugh class. Results:One hundred twenty-fi ve patients (104 men and 21 women; mean age, 55.7 years; age range, 33.4-83.0 years) were included. The median overall survival was 3.7 months (range, 0.2-33.3 months). Eighty-three of the 125 patients (66.4%) were treated with TACE and 42 (33.6%) received supportive care. Repeated TACE showed significant survival benefi ts compared with supportive care in patients with Child-Pugh class A (median survival, 7.4 months vs 2.6 months, respectively; P , .001) and class B (median survival, 2.8 months vs 1.9 months, respectively; P = .002) disease. Results of multivariate analysis showed that treatment with TACE (hazard ratio, 0.263; 95% confi dence interval [CI]: 0.164, 0.424; P , .001) and Child-Pugh class A status (hazard ratio, 0.550; 95% CI: 0.368, 0.822; P = .004) were independent predictive factors of a favorable outcome. There were no procedurerelated deaths within 4 weeks after TACE, and patient morbidity was 28.9% (24 of 83 patients). Conclusion:TACE can be performed safely and may improve the overall survival of patients with HCC and MPV invasion.q RSNA, 2011

The results of this study indicated that cHCC-CC had a significantly poorer prognosis than HCC and CC even after curative resection.

While screening extracts of natural products in search of anticholinesterase activity, we found that a total methanolic extract of the tuber of Corydalis ternata (Papaveraceae) showed significant inhibitory effects on acetylcholinesterase. Further fractionation of this extract using acetylcholinesterase inhibition as the parameter screened resulted in the isolation and purification of an alkaloid, protopine. Protopine inhibited acetylcholinesterase activity in a dose-dependent manner. The concentration required for 50% inhibition was 50 microM. The anti-acetylcholinesterase activity of protopine was specific reversible and competitive in manner. Furthermore, when mice were pretreated with protopine, the alkaloid significantly alleviated scopolamine-induced memory impairment. In fact, protopine had an efficacy almost identical to that of velnacrine, a tacrine derivative developed by a major drug manufacturer to treat Alzheimer's disease, at an identical therapeutic concentration. We suggest, therefore, that protopine has both anti-acetylcholinesterase and antiamnesic properties that may ultimately hold significant therapeutic value in alleviating certain memory impairments observed in dementia.

Resilience potentially mitigated the negative effects of pain. Moreover, it independently contributed to reduced depression and greater post-traumatic growth. Our findings suggest that resilience might provide a potential target for intervention in SCI individuals.
