Downregulation of microRNA-382 is associated with poor outcome of esophageal squamous cell carcinoma.

Aim: To study the potential prognostic role of microRNA-382 (miR-382) in esophageal squamous cell carcinoma (ESCC).

Methods: Forty six patients were divided into 2 groups according to postoperative survival time: the poor outcome group (28 patients), who showed early metastasis but no recurrence, and died within 1 year after surgery, 12 patients of the group received postoperative chemotherapy treatment that was given after early metastasis happening; the good outcome group (18 patients), who had no clinical metastasis and recurrence, and survived 5 years or more after surgery, all patients did not receive any postoperative treatment. Total RNA was extracted from the patients' formalin-fixed and paraffin-embedded esophageal cancer tissues.

[Expression of activin A in tissue and serum of patients with esophageal squamous cell carcinoma and its clinical significance].

Objective: The aim of this study was to explore the expression of activin A in esophageal squamous cell carcinoma and its clinical significance.

Methods: Immunohistochemical (IHC) staining was used for detecting the expression of tissue activin A in sixty-four patients with esophageal squamous cell carcinoma, and enzyme-linked immunosorbent assay (ELISA) was used for detecting the serum activin A in the patients before and after surgery. The relationship between expression of activin A in the esophageal cancer tissue with clinicopathological features and its influence on prognosis were analyzed.

Involvement of microRNA-198 overexpression in the poor prognosis of esophageal cancer.

Objective: This study aimed to investigate whether the miR-198 expression level is related to clinicopathological factors and prognosis of esophageal cancer.

Methods: MicroRNA was extracted from esophageal cancer patients who underwent surgery for assessment using the Taqman@ MicroRNA assay. The correlation between miR-198 expression and clinicopathological features was analyzed, and the significance of miR-198 as a prognostic factor and its relationship with survival was determined.

Differential expression of miRNAs in esophageal cancer tissue.

The aim of this study was to explore the association of specific microRNAs (miRNAs) with the development of esophageal cancer (EC) and to identify new molecular markers for EC by analyzing the expression profiles of miRNAs in EC tissues. The expression profiles of miRNAs in paired EC and paracancerous normal tissues were detected and bioinformatically analyzed using miRNA assays. The outcomes were validated using real-time polymerase chain reaction.

Screening of microRNA in patients with esophageal cancer at same tumor node metastasis stage with different prognoses.

Patients at the same pathological stage of esophageal cancer (EC) that received the same surgical therapy by the same surgeon may have distinct prognoses. The current study aimed to explore the possibility of differentially- expressed microRNAs (miRNAs) underlying this phenomenon. Samples were collected from EC patients at the same tumor node metastasis (TNM) stage but with different prognoses.

[Distribution of Pb and Zn in transgenic metallothionein tobacco].

Transgenic metallothionein (MT) plant can clear the heavy metals from soil and environment, but the distribution of metals in plants has not been studied systematically. The Pb and Zn contents in different parts of transgenic MT tobacco plant of sixth generation and traditional plant (same culture variety as control) were analyzed. The Pb and Zn contents in total transgenic plant were 21.

Stem cells and cancer: evidence for bone marrow stem cells in epithelial cancers.

Cancer commonly arises at the sites of chronic inflammation and infection. Although this association has long been recognized, the reason has remained unclear. Within the gastrointestinal tract, there are many examples of inflammatory conditions associated with cancer, and these include reflux disease and Barrettos adenocarcinoma of the esophagus, Helicobacter infection and gastric cancer, inflammatory bowel disease and colorectal cancer and viral hepatitis leading to hepatocellular carcinoma.

[Effects of hypertonic saline on erythrocyte adherence function and bacterial infection of hemorrhagic shock rabbits].

Aim: To explore the effect of hypertonic saline on the erythrocyte adherence function and bacterial infection of hemorrhagic shock rabbits.

Methods: 60 Japanese rabbits were randomly divided into 6 groups, 10 for each group. Artery catheterization and heparin were given to the rabbits in group 1 (sham shock group).
