MicroRNAs have been documented playing key roles in cancer development and progression. Here, we investigate the role of miR-125b in gastric cancer metastasis. We found that the expression of miR-125b was up-regulated in gastric cancer tissue specimens compared with their corresponding nontumorous tissues, and the up-regulated miR-125b level was significantly associated with TNM stage and lymph node-metastasis.

Delayed traumatic diaphragmatic hernia: A case-series report and literature review.

Background: Traumatic diaphragmatic hernias (TDHs) are sometimes difficult to identify at an early stage and can consequently result in diagnostic delays with life-threatening outcomes. It is the aim of this case study to highlight the difficulties encountered with the earlier detection of traumatic diaphragmatic hernias.

Methods: Clinical data of patients who received treatment for delayed traumatic diaphragmatic hernias in registers of the First Affiliated Hospital of Xi'an Jiaotong University from 1998 to 2014 were analyzed retrospectively.

Recovery of Urinary Functions After Laparoscopic Total Mesorectal Excision for T4 Rectal Cancer.

Background: Postoperative urinary dysfunction after total mesorectal excision (TME) is lessened by preservation of the autonomic nerves, but in T4 rectal tumors such injury often cannot be prevented. This retrospective study evaluated the recovery of urinary function of patients with injury to a single pelvic autonomic nerve subsequent to laparoscopic TME, relative to patients without nerve damage.

Methods: Patients with T4 rectal cancer who underwent laparoscopic TME were divided according to the presence of a single pelvic autonomic nerve injury (37 cases) or no injury to autonomic nerves (54 cases; control).

HOTTIP and HOXA13 are oncogenes associated with gastric cancer progression.

A long non-coding RNA named HOTTIP (HOXA transcript at the distal tip) coordinates the activation of various 5' HOXA genes which encode master regulators of development through targeting the WDR5/MLL complex. HOTTIP acts as an oncogene in several types of cancers, whereas its biological function in gastric cancer has never been studied. In the present study, we investigated the role of HOTTIP in gastric cancer.

[Effects of β-elemene on proliferation and apoptosis of SGC7901 gastric cancer cells in vitro and the underlying mechanisms].

Objective: To investigate the effects of β-elemene in suppressing the proliferation and apoptosis of SGC7901 gastric cancer cells in vitro and explore the underlying mechanisms.

Methods: Using MTT assay, flow cytometry, and clonogenic survival assay, we assessed the effects of β-elemene on the viability, apoptosis, cell cycle distribution, and clonogenic survival of gastric cancer SGC7901 cells and gastric mucosal epithelial GES-1 cells. Western blotting was employed to determine the changes in the protein expression profiles in SGC7901 cells in response to β-elemene treatment.

β-elemene enhances the radiosensitivity of gastric cancer cells by inhibiting Pak1 activation.

Aim: To explore the potential of β-elemene as a radiosensitizer for gastric cancer cells and the underlying mechanisms.

Methods: SGC7901, MKN45, MKN28, N87, and AGS human gastric cancer cell lines were used to screen for radioresistant gastric cancer cell lines. A 3-(4,5-dimeth-ylthiazol-2-yl)-2,5-diphenyltetrazolium (MTT) assay was used to determine the effects of β-elemene and IPA-3 on cell viability in MKN45 and SGC7901 gastric cancer cell lines.

The impact of insulin on chemotherapeutic sensitivity to 5-fluorouracil in gastric cancer cell lines SGC7901, MKN45 and MKN28.

Background: The role of insulin in the pathogenesis of cancer has been increasingly emphasized because of the high incidence of obesity and metabolic syndrome and their correlated complication including cancer. This study aimed to explore the impact of insulin on chemoresistance to 5-fluorouracil in gastric cancer and the possible mechanisms.

Methods: Tissue samples of gastric cancer and adjacent normal gastric mucosa from patients with or without obesity were performed immunohistochemical staining for P-glycoprotein.

SIRT1 is a regulator of autophagy: Implications in gastric cancer progression and treatment.

Silent mating type information regulation 1 (SIRT1) is implicated in tumorigenesis through its effect on autophagy. In gastric cancer (GC), SIRT1 is a marker for prognosis and is involved in cell invasion, proliferation, epithelial-mesenchymal transition (EMT) and drug resistance. Autophagy can function as a cell-survival mechanism or lead to cell death during the genesis and treatment of GC.

[Down-expression of FOXA2 in gastric adenocarcinoma].

Objective: To investigate the expression of FOXA2 in human gastric adenocarcinoma and its correlation with cell migration and invasion.

Methods: Fifty-six pairs of gastric adenocarcinoma and matched tumor-adjacent tissues were freshly collected. The expressions of FOXA2 and epithelial cadherin (E-cadherin) in the gastric specimens were detected using immunohistochemistry.

MicroRNA-153 acts as a prognostic marker in gastric cancer and its role in cell migration and invasion.

MicroRNA (miRNA)-153 (miR-153) has been considered as a novel tumor-related miRNA and is found to be significantly deregulated in human cancers. In this study, we found that the expression levels of miR-153 were obviously lower in gastric cancer tissues than those in matched adjacent nontumor tissues. Otherwise, miR-153 was expressed at significantly lower levels in aggressive tumor tissues.
