The influence of a contemporaneous portal and hepatic artery revascularization protocol on biliary complications after liver transplantation.

Background: We sought to compare the impact of sequential and contemporaneous revascularizations of portal vein and hepatic artery on biliary complications in patients undergoing liver transplantation.

Methods: We reviewed 184 patients who underwent liver transplantation in our center, and categorized them into different groups based on the duration of time between the portal venous and hepatic arterial reperfusion: >10 minutes in the sequential portal and hepatic artery revascularization group (SPA; n = 56), and within 1 minute in the contemporaneous portal and hepatic artery revascularization group (CPA; n = 121).The other patients with an interval from 1-10 minutes (n = 7) were excluded.

Successful treatment of extensive intestinal perforations from Behcet's disease involving the whole gut: a case report.

Intestinal perforation resulting from Behcet's disease has been previously well recognized. To date, fewer than 100 cases of this nature have been reported. Nearly the entire digestive system can be involved, including esophageal, gastric, duodenal, ileum, colon and anal tissues.

Expression of dishevelled gene in Hirschsprung's disease.

Unlabelled: Hirschsprung's disease (HSCR) is a congenital disorder of the enteric nervous system and is characterized by an absence of enteric ganglion cells in terminal regions of the gut during development. Dishevelled (DVL) protein is a cytoplasmic protein which plays pivotal roles in the embryonic development. In this study, we explore the cause of HSCR by studying the expression of DVL-1 and DVL-3 genes and their proteins in the aganglionic segment and the ganglionic segment of colon in HSCR patients.

Antitumor efficacy of C-X-C motif chemokine ligand 14 in hepatocellular carcinoma in vitro and in vivo.

C-X-C motif chemokine ligand 14 (CXCL14) is a novel gene that is expressed in many normal cells but is absent from or expressed at very low levels in cancerous tissues such as head and neck squamous cell carcinoma (HNSCC), prostate cancer, and pancreatic cancer. However, the relationship between CXCL14 and hepatocellular carcinoma (HCC) remains unclear. Therefore, the exact function of CXCL14, which may modulate antitumor immune responses in certain cancers, was evaluated.

Decreased enteric fatty acid amide hydrolase activity is associated with colonic inertia in slow transit constipation.

Background: Constipation is one of the most common chronic digestive complaints. Gastrointestinal transit studies have divided it into three patterns: normal transit, slow transit constipation (STC), and outlet obstruction. It has been demonstrated that STC patients respond poorly to standard therapies, and the etiology of STC remains poorly understood.

A case report of de novo hepatocellular carcinoma after living donor liver transplantation.

Post-transplant malignancy is the major cause of later death of recipients after liver transplantation. Tumor recurrence after liver transplantation for patients with hepatocellular carcinoma in the end stage of cirrhosis has been frequently encountered. However, de novo hepatocellular carcinoma originating from the liver allograft has only rarely been reported.

Polymorphisms and expression of the WNT8A gene in Hirschsprung's disease.

Hirschsprung's disease (HSCR) is a congenital disorder characterized by an absence of intrinsic ganglion cells in the nerves forming the plexus of the lower intestine. The WNT signaling pathway is considered to play an important role in embryonic development. In the present study, we analyzed 2 polymorphisms of the WNT8A gene (rs78301778 and rs6596422) to determine their association with the risk and development of HSCR.

Histone deacetylase inhibitors modulate miRNA and mRNA expression, block metaphase, and induce apoptosis in inflammatory breast cancer cells.

To develop new therapies for inflammatory breast cancer (IBC) we have compared the effects of two hydroxamic acid-based histone deacetylase (HDAC) inhibitors, CG-1521 and Trichostatin A (TSA) on the biology of two IBC cell lines: SUM149PT and SUM190PT. CG-1521 and TSA induce dose (0-10 µM) and time-dependent (0-96 h) increases in the proportion of cells undergoing cell cycle arrest and apoptosis in the presence or absence of 17β-estradiol. In SUM 149PT cells, both CG-1521 and TSA increase the levels of acetylated α-tubulin; however the morphological effects are different: CG-1521 blocks mitotic spindle formation and prevents abscission during cytokinesis while TSA results in an increase in cell size.

Mitochondrial dysfunction-related genes in hepatocellular carcinoma.

Mitochondria dysfunction is associated with apoptotic resistance and metabolism of tumor cells. Hepatocellular carcinoma (HCC) is a complex and heterogeneous tumor with multiple genetic aberrations. Certain gene mutations in mitochondria may lead to mitochondrial dysfunction.

Anorectal malformation associated with a mutation in the P63 gene in a family with split hand-foot malformation.

Purpose: The aims of this study were to identify the mutation gene of a Chinese family with anorectal malformation (ARM) associated with split hand-foot malformation and to determine the spatiotemporal expression of the mutated gene during hindgut and anorectum development in human embryos.

Method: A Chinese family with intrafamilial clinically variable manifestation was analyzed and primers were designed for exons 3-14 of P63, DLX5, DLX6, DAC, and HOXD13 as candidate genes and direct sequence analysis of the exons was performed. Immunohistochemical study of mutated gene in the hindgut and anorectum of human embryos of 4th-10th weeks was performed.

miR-9*- and miR-124a-Mediated switching of chromatin remodelling complexes is altered in rat spina bifida aperta.

Neural tube defects (NTDs) are complex congenital malformations resulting from incomplete neurulation. Our previous work has demonstrated that motor and sensory neurons develop defectively in rat embryos with spina bifida aperta. To identify whether neural development-associated miRNAs play a role in the neurological deficits of NTDs, we screened a panel of neural development-related miRNAs, including miR-9, miR-9*, miR-124a, miR-10a, miR10b, miR-34a, miR-221 and miR-222, in the spinal cords of rats with retinoic acid-induced spina bifida aperta.

Comparative proteomics of Hirschsprung's disease.

Unlabelled: Hirschsprung's disease (HSCR) is a developmental disorder of the enteric nervous system characterized by aganglionosis in distal gut. The estimated population incidence of HSCR is 1/5000 live births, but higher in Asian populations. As the disease mainly manifested bowel motility disturbance, the underlying mechanism is unknown.

Management hepatolithiasis with operative choledochoscopic FREDDY laser lithotripsy combined with or without hepatectomy.

Background: Hepatolithiasis is very common in East Asia. It is benign in nature, but has a high recurrence rate. It is likely to lead to biliary cirrhosis and increase the risk of cholangiocarcinoma.

Mid-Neolithic exploitation of mollusks in the Guanzhong Basin of Northwestern China: preliminary results.

Mollusk remains are abundant in archaeological sites in the Guanzhong Basin of Northwestern China, providing good opportunities for investigations into the use of mollusks by prehistoric humans. Here we report on freshwater gastropod and bivalve mollusks covering the time interval from about 5600 to 4500 cal. yrs BP from sites of Mid-Late Neolithic age.

Nonoperative management of appendiceal phlegmon or abscess with an appendicolith in children.

Background: The optimal treatment of appendiceal phlegmon or abscess with an appendicolith is controversial. This study aimed to evaluate outcomes and prognosis of nonoperative management of appendiceal phlegmon or abscess with an appendicolith in children.

Methods: From 2007 to 2011, 105 children with appendiceal phlegmon or abscess who were treated nonoperatively without interval appendectomy were reviewed.

Liver transplantation in Crigler-Najjar syndrome type I disease.

Background: Crigler-Najjar syndrome type I (CNS I) is a very rare autosomal recessive inherited disease that liver transplantation can properly deal with.

Methods: We present one case of an 18-month-old child with CNS I diagnosed by clinical findings and genetic detecting. LTx was performed 5 days after kernicterus broke out and neurological symptoms were successfully reversed.

1,25-Dihydroxyvitamin D3 modulates lipid metabolism in prostate cancer cells through miRNA mediated regulation of PPARA.

Previous studies from our laboratory have shown that testosterone (T) and 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) co-operate to inhibit cell proliferation and induce significant changes in gene expression and differentiation in LNCaP cells. The data presented here demonstrate that the two agents alter fatty acid metabolism, and accumulation of neutral lipid. Concurrent genome wide analysis of mRNA and miRNA in LNCaP cells reveals an extensive transcription regulatory network modulated by T and 1,25(OH)2D3.

Engineered measles virus Edmonston strain used as a novel oncolytic viral system against human hepatoblastoma.

Background: Hepatoblastoma (HB) is the most common primary, malignant pediatric liver tumor in children. The treatment results for affected children have markedly improved in recent decades. However, the prognosis for high-risk patients who have extrahepatic extensions, invasion of the large hepatic veins, distant metastases and very high alpha-fetoprotein (AFP) serum levels remains poor.

Study of InN epitaxial films and nanorods grown on GaN template by RF-MOMBE.

This paper reports on high-quality InN materials prepared on a GaN template using radio-frequency metalorganic molecular beam epitaxy. We also discuss the structural and electro-optical properties of InN nanorods/films. The X-ray diffraction peaks of InN(0002) and InN(0004) were identified from their spectra, indicating that the (0001)-oriented hexagonal InN was epitaxially grown on the GaN template.

Castleman disease mimicked pancreatic carcinoma: report of two cases.

Castleman disease (CD) is an uncommon benign lymphoproliferative disorder, which usually presents as solitary or multiple masses in the mediastinum. Peripancreatic CD was rarely reported. Herein, we report two cases of unicentric peripancreatic CD from our center.

Engineered measles virus Edmonston strain used as a novel oncolytic viral system against human neuroblastoma through a CD46 and nectin 4-independent pathway.

Neuroblastoma (NB) is the most common extracranial solid tumor in children. In this study, we investigated the potential antitumor capability of the engineered Edmonston strain of the carcinoembryonic antigen-expressing measles virus (MV-CEA) against human NB. The infection of a variety of NB cell lines, including SK-N-SH, SMS-KCNR, and primary NB cells, resulted in significant cytopathic effects.

Long-term survival after chemoembolization of metastatic right atrial tumor thrombus as a presenting feature of hepatocellular carcinoma: A case study.

Advanced hepatocellular carcinoma (HCC) with invasion into the heart through the hepatic vein is a recognized rare occurrence with an extremely poor prognosis. Patients who present with right heart tumor thrombus have generally been considered inoperable. Although aggressive resection and liver transplantation treatment have previously been performed, the results remain unsatisfactory.

Diagnostic role of microRNA expression profile in the serum of pregnant women with fetuses with neural tube defects.

The discovery of placental microRNAs (miRNAs) in maternal serum has opened up new possibilities for non-invasive prenatal diagnosis. However, the expression of miRNAs in the serum of pregnant women with fetuses with neural tube defects (NTDs) has not been characterized. In this article, we explored serum miRNAs as potential biomarkers in the serum of pregnant women with NTD fetuses.
