Subsequently to the publication of the above article, an interested reader drew to the authors' attention that two pairs of data panels featured in Figs. 2E and 6D, portraying the results from cell invasion and migration assay experiments, appeared to contain overlapping sections, such that data which were intended to show the results from differently performed experiments had apparently been derived from a smaller number of original sources. The authors were able to re‑examine their original data (which was also presented to the Editorial Office), and realized that errors has been made in the compilation of Fig.

Long non‑coding RNAs can regulate the malignant tumor phenotype either as tumor suppressors or oncogenes. The present study investigated the underlying mechanism of LINC00238 in liver cancer. LINC00238 was identified as a downregulated molecule in The Cancer Genome Atlas liver hepatocellular carcinoma dataset through Gene Expression Profiling Interactive Analysis software.

The combination of nitric oxide (NO) and siRNA is highly desirable for cancer therapy. Here, the furoxans-grafted PEI polymer (FDP) with caspase-3 responsive cleavable DEVD linker was synthesized, and used to bind siRNAs via electrostatic interaction and self-assembled into FDP/siRNA nanoplexes by hydrophobic force. After cellular uptake and lysosomal escape, the FDP/siRNA nanoplexes could achieve GSH-triggered NO release, and then increase the activity of caspase-3.

Lanthanum can reduce absorption of phosphate by forming lanthanum phosphate complexes after oral administration of lanthanum carbonate tablets (FOSRENOL®) in patients. Based on the pH-responsive interaction of phosphate and lanthanum ions, the chitosan coated siRNA-loaded lanthanum phosphate nanoparticles (CS/LaP/siRNA NPs) were prepared for improving cancer treatment, in which polysaccharide chitosan was used as the outer shell to control the excessive growth of lanthanum phosphate complexes, and enable intestinal mucoadhesion. The CS/LaP/siEGFR NPs exhibited significant biological activities in human colorectal cancer HT-29 cells by the synergistic effects of siEGFRs and lanthanum ions, such as downregulation of EGFR and upregulation of miR-34a.

Although microRNAs (miRNAs) function as the important tumor gene regulators, they still confront with many challenges in systemic delivery. Here, the amphiphilic gemcitabine-oleic acid prodrugs (GOA) binding miRNAs with hydrogen bond are assembled into nanoparticles (GOA/miR NPs) through hydrophobic interaction via denaturation-annealing processes and nano-precipitation technique. The non-cationic GOA/miR NPs with an average size of ~150 nm and a zeta potential of ~ - 15 mV exhibit a stable encapsulation of miRNAs with non-sequence selectivity.

Tumor samples of pancreatic ductal adenocarcinoma patients, who underwent resection surgery, were implanted into NOD/SCID mice to construct pancreatic cancer patient-derived xenograft (PDX) models and explore the biological changes in the different generations of PDXs. Ten PDXs were successfully generated, and the tumor formation rate of F1 PDXs was found to be 38.46%, which was lower than F2 (77.

The precise intraoperative navigation of the surgical plane remains challenging in liver surgery; however, an innovative imaging technique-real-time virtual sonography (RVS)-may provide a solution. In this modality, preoperative three-dimensional (3D) resection simulation data are transmitted to an RVS workstation and can be used in combination with intraoperative ultrasound to navigate the surgical plane in real time. This paper describes this technique and our experiences in detail.

Aims: To compare the short- and long-term outcomes in patients with pancreatic benign or borderline neoplasm who underwent central pancreatectomy (CP) and distal pancreatectomy (DP).

Methods: The inclusion criteria were as follows: (1) single benign or low-grade malignant tumor; (2) tumor confined to the pancreatic neck or proximal body; and (3) tumor amenable to either CP or DP. Short and long-term outcomes, including complications, pancreatic exocrine and endocrine function, and quality of life (QoL) were analyzed retrospectively.

Background: Delayed postoperative arterial bleeding is rare and may be life-threatening. When the bleeding source is the hepatic artery, complete ligation or embolization from the proximal to the distal area of the ruptured lesion usually results in complete occlusion of hepatic arterial flow.

Methods: To evaluate the frequency and severity of ischemic liver injury following complete hepatic artery occlusion, a retrospective study was conducted.

Reactive lymphoid hyperplasia is a rare disease that forms a mass-like lesion and is characterized by the proliferation of non-neoplastic, polyclonal lymphocytes forming follicles. We recently encountered 2 cases of reactive lymphoid hyperplasia of liver, both of which were asymptomatic and mimicked hepatocellular carcinoma by various imaging modalities. Based on the clinical impression of hepatocellular carcinoma, surgical resections were performed.

Background/aims: The relationships between Hepatitis B virus infection, cirrhosis and colorectal cancer liver metastasis have not been investigated simultaneously and it remained unclear that whether the immune changes caused by Hepatitis B virus infection or the structural changes caused by cirrhosis conduce to the lower incidence of liver metastasis.

Methodology: Data of 1413 colorectal cancer patients were reviewed to investigate the impacts of Hepatitis B virus infection and cirrhosis on the occurrence and prognosis of liver metastasis.

Results: The incidence of liver metastasis in the Hepatitis B virus infection group or in the cirrhotic group was lower than the control groups (9.

Background: Carcinoma of the right colon invading the pancreas or duodenum is rare. Evidence of the indication, operative morbidity, and survival of en bloc pancreaticoduodenectomy and right colectomy for right colon cancer invading adjacent organs is limited.

Objective: : The goal of this study was to investigate the feasibility, safety, indication, and long-term results of en bloc pancreaticoduodenectomy and right colectomy in the treatment of locally advanced right-sided colon cancer.

Liver is the most common metastatic site of gastrointestinal stromal tumor(GIST). The recurrence rate is high even after hepatectomy. Although tyrosine kinase inhibitors (TKI) makes the resection feasible for some of the liver metastasis of GIST and significantly increase the overall survival, surgery still can not be substituted.

Objective: To investigate the diagnosis and treatment of delayed post-pancreaticoduodenectomy arterial bleeding (DPPAB).

Methods: Records of 336 patients who underwent pancreaticoduodenectomy (PD) between January 2000 and December 2010 were retrospectively analyzed. Detailed data of patients with DPPAB were assessed by a thorough review of medical records.

Objective: To establish a scoring system predicting the ascites postoperatively by analyzing the variant factors associated with massive ascites after hepatectomy in the patients with hepatocellular carcinoma (HCC).

Methods: From January 2005 to January 2010, 324 patients with HCC underwent hepatectomy were analyzed retrospectively. There were 282 male and 42 female, aging from 17 to 84 years (mean age, 54 years).

Introduction: The feasibility and safety of pancreaticoduodenectomy (PD) combined with long segmental mesentericoportal vein (MPV; >5 cm) resection and end-to-end anastomosis without graft has rarely been demonstrated.

Materials And Methods: Eight patients with pancreatic head adenocarcinoma underwent PD combined with long MPV resection between August 2006 and May 2008 in Peking University School of Oncology.

Results: By liver mobilization and Cattell-Braasch maneuver, direct and tension-free end-to-end anastomosis was easily performed even when the resected segment of the MPV was longer than 5 cm.

Aim: To explore the preliminary identification of serum protein pattern models that may be novel potential biomarkers in the detection of gastric cancer.

Methods: A total of 130 serum samples, including 70 from patients with gastric cancer and 60 from healthy adults, were detected by surface-enhanced laser desorption and ionization time-of-flight mass spectrometry (SELDI-TOF-MS). The data of spectra were analyzed by Biomarker Patterns Software (BPS).
