Identification of resection plane for anatomical liver resection using ultrasonography-guided needle insertion.

Purposes: To set up an easy-handled and precise delineation of resection plane for hepatic anatomical resection (AR).

Methods: Cases of AR using ultrasonography-guided needle insertion to trace the target hepatic vein for delineation of resection planes [new technique (NT) group,  = 22] were retrospectively compared with those without implementation of this surgical technique [traditional technique (TT) group,  = 29] in terms of perioperative courses and surgical outcomes.

Results: The target hepatic vein was successfully exposed in all patients of the NT group, compared with a success rate of 79.

Long non-coding RNA HOXB-AS1 is a prognostic marker and promotes hepatocellular carcinoma cells' proliferation and invasion.

Long non-coding RNAs (lncRNAs) are broadly transcribed in the genome of human and play critical roles in the progression of multiple diseases. Long non-coding HOXB cluster antisense RNA 1 (HOXB-AS1) is a tumor exciter in various cancers. This study aimed to investigate the involvement of HOXB-AS1 in hepatocellular carcinoma (HCC).

MicroRNA-1269 promotes proliferation in human hepatocellular carcinoma via downregulation of FOXO1.

Background: Hepatocellular carcinoma (HCC) is one of the most common malignancies and a major cause of cancer-related mortality in the world. MicroRNAs (miRNAs) are small, noncoding RNAs that play essential roles in various stages during cancer progression. The aim of the current study was to elucidate the role of miR-1269 in the pathogenesis of HCC.

[Transforming growth factor β1 cooperates with stromal cell derived factor 1 to affect the proliferation of hepatic oval cells via β-catenin inactivation].

Objective: To investigate the role of stromal cell derived factor 1 (SDF-1) on the proliferation of hepatic oval cells, and the influencing factors.

Methods: Flow cytometry was used to detect the expression of CXCR4 on the cell surface when WB-F344 cells were growing in the culture medium with and without transforming growth factor β1 (TGF-β1) respectively. Western bolt was used to detect the expression of β-catenin and its phosphorylation level.

The impact of chemotherapy-associated neutrophil/ lymphocyte counts on prognosis of adjuvant chemotherapy in colorectal cancer.

Background: Leukocytes play an important role in cancer development. However, the impact of chemotherapy-associated neutropenia/lymphopenia on the prognosis of adjuvant chemotherapy is unknown. Here, we aimed to explore the impact of chemotherapy-associated neutrophil/lymphocyte counts on prognosis of adjuvant chemotherapy in colorectal cancer (CRC) and the risk factors for developing neutropenia/lymphopenia which showed impact on the prognosis of CRC receiving adjuvant chemotherapy.

Islet isolation and purification from inbred Wuzhishan miniature pigs.

Background: To investigate the applicability of inbred Wuzhishan (WZS) miniature pigs for porcine islet isolation and purification.

Methods:  Islet isolation and purification was conducted on adult (1-yr-old), male inbred WZS miniature pigs and age- and sex-matched market pigs obtained from a local slaughterhouse (control group). Pancreata were excised, and islet isolation was carried out by static digestion and discontinuous gradient centrifugation.

MicroRNA-590-5p regulates proliferation and invasion in human hepatocellular carcinoma cells by targeting TGF-β RII.

MicroRNAs (miRNAs) are regulatory small non-coding RNAs that can regulate gene expression by binding to gene elements, such as the gene promotor 5'UTR, mainly in the 3'UTR of mRNA. One miRNA targets many mRNAs, which can be regulated by many miRNAs, leading to a complex metabolic network. In our study, we found that the expression level of miR-590-5p is higher in the human hepatocellular carcinoma cell line HepG2 than in the normal hepatocellular cell line L02.

Green tea polyphenol epigallocatechin-3-gallate enhances 5-fluorouracil-induced cell growth inhibition of hepatocellular carcinoma cells.

Aim:   5-Fluorouracil (5-FU) is one of the most commonly used chemotherapeutic drugs. Resistance to 5-FU is a major cause of chemotherapy failure in advanced-stage hepatocellular carcinoma (HCC). Green tea polyphenol Epigallocatechin-3-gallate (EGCG) plays a critical role in growth inhibition and apoptotic induction in HCC cell lines.

Rosiglitazone enhances 5-fluorouracil-induced cell growth inhibition in hepatocellular carcinoma cell line Hep3B.

Background And Objective: Rosiglitazone is a peroxisome proliferators-activated receptor gamma (PPARgamma) ligand, which inhibits tumor growth by activating PPARgamma signaling pathways. Fluorouracil (5-FU) is one of the commonly used chemotherapeutic drugs. However, patients develop drug resistance of 5-FU over time.

[Risk factors of survival for recurrent hepatocellular carcinoma treated by percutaneous radiofrequency ablation].

Objective: To explore the efficacy and determine the risk factors of survival for recurrent hepatocellular carcinoma(HCC) treated by percutaneous radiofrequency ablation (PRFA).

Methods: From January 1999 to December 2008, 82 patients with recurrent HCC, with the diameter less than 7 cm for solitary tumor, or the largest tumor less than 5 cm for multiple tumors(the number of tumors less than 3), were treated by PRFA. The significance of 12 clinical or pathological variables in the risk factors of overall survival were assessed.

Efficacy of combining temperature- and power-controlled radiofrequency ablation for malignant liver tumors.

Background And Objective: Single mode of radiofrequency ablation (RFA) often leads to limited ablation in the zone of necrosis. This study clarifies the efficacy of combining temperature- and power-controlled RFA for malignant liver tumors.

Methods: Between April 2008 and August 2008, 58 patients with malignant liver tumors received RFA at Sun Yat-sen University Cancer Center.

Rosiglitazone sensitizes hepatocellular carcinoma cell lines to 5-fluorouracil antitumor activity through activation of the PPARgamma signaling pathway.

Aim: Resistance to 5-fluorouracil (5-FU) is a major cause of chemotherapy failure in advanced hepatocellular carcinoma (HCC). Rosiglitazone, a peroxisome proliferator-activated receptor gamma (PPARgamma) agonist, has a crucial role in growth inhibition and induction of apoptosis in several carcinoma cell lines. In this study, we examine rosiglitazone-induced sensitization of HCC cell lines (BEL-7402 and Huh-7 cells) to 5-FU.
