    ABSTRACT: We report our experience of endovascular management and postoperative aortic remodeling of all types of isolated abdominal aortic dissection (IAAD). This was retrospective study of 28 IAAD patients treated by endovascular means in our department between January 2007 and July 2013. We reviewed the risk factors, clinical features, computed tomography images, follow-up results, and aortic remodeling of these IAAD patients and propose a new morphologic classification into three types-supraceliac, paravisceral, and infrarenal-according to the location of the primary entry site. There were four supraceliac IAADs, one paravisceral IAAD, and 23 infrarenal IAADs in our case series. Suprarenal (supraceliac + paravisceral) IAAD patients were relatively younger than infrarenal patients (45.2 ± 8.6 years vs 60.6 ± 15.5 years; P < .05). No difference was observed between suprarenal and infrarenal IAADs with respect to true lumen, false lumen, and dissection length on imaging (P > .05). All patients received endovascular treatment. The primary technical success rate was 100%. During a follow-up of 35.7 ± 19.9 months, only one infrarenal patient needed an endovascular reintervention. All patients with supraceliac or infrarenal IAADs were alive at the time of follow-up; however, a paravisceral patient died of a dissecting abdominal aortic aneurysm rupture 21 months after endovascular treatment. In the suprarenal and infrarenal groups, endovascular treatment was associated with a significant decrease in the false lumen size and increase in the true lumen size (P < .05). The maximum abdominal aorta diameter decreased after endovascular treatment in both groups but was statistically significant only in the infrarenal group (P < .05). IAAD is a rare vascular disease. We propose it should be categorized as supraceliac, paravisceral, and infrarenal IAAD according to the location of the primary entry site. Endovascular treatment for supraceliac and infrarenal IAADs is a safe method with a high technical success rate and promising aortic remodeling, whereas endovascular treatment for paravisceral IAADs remains difficult.

    ABSTRACT: Mucormycosis is a rare but potentially lethal complication of liver transplantation. Most reported cases have involved rhinocerebral, pulmonary, gastrointestinal, or disseminated forms. We present herein the case of a 61-year-old male patient with hepatocellular carcinoma who developed isolated penile mucormycosis after orthotopic liver transplantation. Such a case has not been reported in the literature to date. Early diagnosis and timely surgical intervention combined with comprehensive treatment are the key factors for improving the survival rate in patients with mucormycosis. Copyright © 2014 The Authors.

    ABSTRACT: Metastasis-associated lung adenocarcinoma transcript 1(MALAT1), a long non-coding RNA (lncRNA), is up-regulated in many solid tumors and associated with cancer metastasis and recurrence. However, its role in hepatocellular carcinoma (HCC) remains poorly understood. In the present study, we evaluated the expression of MALAT1 by quantitative real-time PCR in 9 liver cancer cell lines and 112 HCC cases including 60 cases who received liver transplantation (LT) with complete follow-up data. Moreover, small interfering RNA (siRNA) was used to inhibit MALAT1 expression to investigate its biological role in tumor progression. We found that MALAT1 was up-regulated in both cell lines and clinical tissue samples. Patients with high expression level of MALAT1 had a significantly increased risk of tumor recurrence after LT, particularly in patients who exceeded the Milan criteria. On multivariate analysis, MALAT1 was an independent prognostic factor for predicting HCC recurrence (hazard ratio, 3.280, P = 0.003).In addition, inhibition of MALAT1 in HepG2 cells could effectively reduce cell viability, motility, invasiveness, and increase the sensitivity to apoptosis. Our data suggest that lncRNA MALAT1 play an important role in tumor progression and could be a novel biomarker for predicting tumor recurrence after LT and serve as a promising therapeutic target.

    ABSTRACT: The long noncoding RNA HOTAIR has been reported as a poor prognostic biomarker in patients with breast cancer. The aim of the present study is to examine the expression pattern of HOTAIR in hepatocellular carcinoma (HCC) and its clinical significance as well as its biological role in tumor progression. We examined the expression of HOTAIR in 110 HCC samples using real-time reverse transcription-polymerase chain reaction and analyzed its correlation with clinical parameters and prognosis in 60 HCC patients that have undergone liver transplantation (LT). Suppression of HOTAIR using siRNA was performed to explore its roles in tumor progression. The expression level of HOTAIR in cancer tissues was higher than in adjacent noncancerous tissues. High expression level of HOTAIR was an independent prognostic factor for predicting HCC recurrence in LT patients (P = .001, hazard ratio, 3.564). Furthermore, in patients exceeding the Milan criteria, those with a high expression level of HOTAIR revealed a significantly shorter recurrence-free survival. Moreover, siRNA suppression of HOTAIR in a liver cancer cell line reduced cell viability and cell invasion, sensitized TNF-α induced apoptosis, and increased the chemotherapeutic sensitivity of cancer cells to cisplatin and doxorubicin. The high expression level of HOTAIR in HCC could be a candidate biomarker for predicting tumor recurrence in HCC patients who have undergone liver transplant therapy and might be a potential therapeutic target.
