Hepatoblastoma (HB) usually occurs in infants and toddlers. Although long non-coding RNAs (lncRNAs) in various human cancers have been widely studied, the role of lncRNAs in HB remains unclear. This study aimed to investigate the biological role of the lncRNA lung cancer associated transcript 1 () in HB.

Tissue microarrays with 236 HCC specimens and 18 extrahepatic metastases were utilized to detect the HDGF expression by immunohistochemistry. Meanwhile, HDGF expressions in HCC cell lines with different metastatic potentials were examined using immunofluorescence staining, real-time PCR and western blotting.

Aim: To investigate the expression of integrin αvβ6 and matrix metalloproteinase 9 (MMP-9), their association with prognostic factors and to assess their predictive role in gastric cancer patients.
Methods: Immunohistochemistry was used to determine the expressions of integrin αvβ6 and MMP-9 in 126 specimens from patients with primary gastric carcinoma. Associations between immunohistochemical staining and various clinic pathologic variables of tissue specimens were evaluated by the χ(2) test and Fisher's exact test.
Aim: To evaluate a different decision tree for safe liver resection and verify its efficiency.
Methods: A total of 2457 patients underwent hepatic resection between January 2004 and December 2010 at the Chinese PLA General Hospital, and 634 hepatocellular carcinoma (HCC) patients were eligible for the final analyses. Post-hepatectomy liver failure (PHLF) was identified by the association of prothrombin time < 50% and serum bilirubin > 50 μmol/L (the "50-50" criteria), which were assessed at day 5 postoperatively or later.
Aim: To detect the mechanism by which colon tumor escapes the growth constraints imposed on normal cells by cell crowding and dense pericellular matrices.
Methods: An immunohistochemical study of integrin αvβ6 and matrix metalloproteinase-9 (MMP-9) was performed on tissue microarrays of 200 spots, including 100 cases of colon tumors.
Results: High immunoreactivity for αvβ6 (73.
Hepatoma-derived growth factor (HDGF) has been reported to be a potential predictive and prognostic marker for several types of cancer and important in malignant biological behaviors. However, its role in human hilar cholangiocarcinoma remains to be elucidated. Our previous study demonstrated that high expression levels of HDGF in hilar cholangiocarcinoma tissues correlates with tumor progression and patient outcome.

Objective: To analyze the surgical management of incidental gallbladder cancer (IGBC) discovered during or after laparoscopic cholecystectomy (LC) and to evaluate the associated factors of survival.
Methods: A retrospective analysis of patients with IGBC between January 2002 and December 2013 was performed. A total of 10 080 consecutive patients underwent LC operation for presumed gallbladder benign disease in Chinese People's Liberation Army General hospital.
Background: The optimal surgical management of patients with incidental gallbladder cancer (IGBC) and their long-term survival remains unclear.
Objective: The purpose of this study was to examine the long-term prognosis of patients with IGBC diagnosed during or after LC.
Methods: Between January 2002 and January 2012, a total of 7,582 consecutive patients underwent LC for presumed gallbladder benign disease in the Chinese PLA General Hospital, China.
Background: The possible role of substance P (SP) during wound healing has been the primary research focus in recent years, but its effect on the healing process after bile duct injury is little understood. This study aimed to investigate the effects of SP on growth of fibroblast-like cells derived from rabbit bile duct.
Methods: Fibroblast-like cells derived from rabbit bile duct were identified and divided randomly into control and experimental groups.
Integrins play an important role in tumor metastasis induced by vascular endothelial growth factor (VEGF). However, in the case of gastric cancer, the precise role of VEGF in regulating integrin alphavbeta6 is unclear. In this study, we found that most of the alphavbeta6 integrin-positive gastric cancer tissues were also VEGF-positive.

Herein, we use the RNA interfering technology to downregulate the expression of alphaupsilonbeta6 in colon cancer cells. Our data demonstrate that plasmid vector based shRNA can effectively down-regulate alphaupsilonbeta6 expression in protein and mRNA levels.

In this study, we investigated the apoptosis and its related signal pathways to integrin alphavbeta6 in colon cancer cells. After we blocked the function of integrin alphavbeta6 in HT29 cells used the monoclonal antibody, the apoptotic cells increased markedly.

To detect the effects of alpha v beta 6 on liver metastasis, the specificity of alpha v beta 6 against the monoclonal antibody (mAb) 2G2 was examined by immunoprecipitation. Integrin alpha v beta 6-immunoreactivity (IR) in liver metastasis tissues (63 cases) and colon carcinoma (358 cases) were examined.

However, RYHJ might also induce ascending cholangitis and recurrent hepatolithiasis. The present study aims to introduce a modified hepatic portal choledochoplasty with a pedicled graft of gallbladder (HPC) to treat this disease.

Methods: Expressing vector of antisense alphavbeta6 was constructed. Human colon cancer cells of the line HT29 were cultured and divided into 3 groups: Group A, remaining wild type; Group B, transfected with antisense integrin beta6 gene; and Group C, transfected with blank vector.
