Radiofrequency ablation combined with transarterial chemoembolization in treatment of hepatocellular carcinoma adjacent to the second hepatic hilus.

Purpose: To explore the efficacy and safety of using radiofrequency ablation (RFA) combined with transarterial chemoembolization (TACE) for treating hepatocellular carcinoma (HCC) adjacent to the second hepatic hilus.

Methods: Between February 2011 and June 2013, 17 patients with HCC underwent combination therapy of TACE and RFA under DSA and CT guidance at our institution. The 17 patients had a total of 23 hepatic tumors, 17 of which were adjacent to the second hepatic hilus.

Simultaneous imaging of cancer biomarkers in live cells based on DNA-engineered exosomes.

Cancer biomarkers are directly related to the development of cancers. Noninvasive identification of the location and expression levels of these biomarkers in live cancer cells offers great potential for accurate early-stage cancer diagnosis and cancer metastasis monitoring. Herein, we propose a DNA-engineered exosome (DNA-Exo) nanoplatform to image dual cancer biomarkers at the single-cell level, in which DNA probes were modified with the cholesterol group to facilely anchor on the exosomal membrane through hydrophobic interaction.

Involvement of 5-HT-BDNF signaling axis in mediating synergistic antidepressant-like effects after combined administration of two oligosaccharide esters.

Potential mechanisms of depression involving herbal medicines and their specific compounds include elevated 5-HT level and downstream BDNF pathway. To identify potentially new combined therapeutic strategies, 3,6'-disinapoylsucrose (DISS) and tenuifoliside A (TFSA) have been observed to show antidepressant-like effects and its related 5-HT-BDNF pathway. We have tried to investigate whether combined administration of DISS and TFSA exerted more effective in the treatment of depression, as assessed through tail suspension test (TST) and forced swimming test (FST).

Efficacy and safety of micafungin for invasive candida infections: a meta-analysis of randomized controlled trials.

Background: Invasive fungal infections such as candidiasis and mold infections cause significant morbidity and mortality in seriously ill patients. Micafungin is an echinocandin antifungal agent with potent activity against most species of Candida and Aspergillus. We did this meta-analysis to clarify whether micafungin offers superior efficacy and safety compared with other antifungal agent for treating infections associated with invasive candidiasis.

Long-term treatment with a "Yang-invigorating" Chinese herbal formula, Wu-Zi-Yan-Zong-Wan, reduces mortality and liver oxidative damage in chronic alcohol-intoxicated rats.

Long-term alcohol consumption has been reported to increase oxidative stress in multiple organs and accelerate the aging process. A previous study in our laboratory has shown that Wu-Zi-Yan-Zong-Wan (WZ), a "Yang-invigorating" Chinese herbal formula, protected against ethanol-induced toxicity in HepG2 cells transfected to express human CYP2E1, presumably by enhancing mitochondrial antioxidant status and functional ability. The present study aims to investigate whether WZ extract treatment can afford protection against chronic ethanol-induced oxidative stress (a major risk factor of aging) and mortality in rats.

Incidence and risk of significantly raised blood pressure in cancer patients treated with bevacizumab: an updated meta-analysis.
