Rationale: Gastrointestinal solitary extramedullary plasmacytoma (EMP) is rare, just occupies about 5% of all EMPs. The most common site is small intestine followed by stomach. The colorectal incidence is much rare.

The present study aimed to demonstrate the potential of lncRNAs to be used as biomarkers in EGC. Reverse transcription‑quantitative polymerase chain reaction was used to measure the expression levels of lncRNAs, including X inactive‑specific transcript (XIST), Yiya, brain cytoplasmic RNA 1 (BCYRN1), ribosomal RNA processing 1B (RRP1B), KCNQ1 opposite transcript 1 (KCNQ1OT1) and testes development related 1 (TDRG1), in EGC tissues compared with normal adjacent tissues (NATs).

The present study included 484 patients with colon cancer that underwent colon resection between December 2003 and December 2011. All follow-ups were censored in December 2013 with a median follow-up time of 43 months.

Among them, polyelectrolyte complexes (PEC) films consisted of chitosan (CS) and sodium alginate (SA) could be obtained via spontaneously assembling under physiological gastrointestinal environment. Here, we utilized these self-assembled PEC films as an efficient coating materials to develop controlled-released matrix tablets through compression coating process, with paracetamol (APAP) as model drug.

CRC is characterized by the changes in the expression levels of biomarkers, including voltage-gated proton channel Hv1, matrix-remodeling associated 5 (MXRA5), DEK (inducing positive supercoils into circular DNA) and protein inhibitor of activated signal transducer and activators of transcription 3 (PIAS3). Thus, sedentary behavior may affect the expression levels of these biomarkers in the colorectal tissue.

But due to the anatomic complexity of the stomach and the duodenum, to a certain degree, there are some technical difficulties in the placement of postpyloric feeding tube, especially in critically ill patients. This study aimed to evaluate the efficacy and safety of placing nasoenteral feeding tube with a transnasal ultrathin endoscope.

Objective: To investigate the expression of GST-pi and Topo II-alpha, and their relationships with clinicopathological parameters in colorectal carcinoma.
Methods: The expression of GST-pi and Topo II-alpha were detected by avidin-biotin-peroxide complex (ABC) method in tumor specimens, matched paratumor tissues from 60 cases with colorectal carcinoma and normal colonic tissues from 15 cases.
Results: The expression rates of GST-pi and Topo II-alpha were 90.
Aim: One-week triple therapy with proton pump inhibitors, clarithromycin and amoxicillin has recently been proposed as the first-line treatment for Helicobacter pylori (H. pylori) infection; however, data regarding the effects of this regimen in China are scarce. The aim of this prospective and randomized study was to compare the efficacy of clarithromycin and metronidazole when they were combined with omeprazole and amoxicillin on eradication of H.

Methods: Thirty-eight patients, with premalignant gastric lesions including 18 colonic-type intestinal metaplasia (IM) and 20 mild or moderate dysplasia, were randomly divided into a treatment group (n = 19) receiving folic acid 10 mg thrice daily and a control group (n = 19) receiving sucralfate 1,000 mg thrice daily for 3 mo. All patients underwent endoscopies and four biopsies were taken prior to treatment and repeated after concluding therapy.

Aim: Cyclooxygenase (COX)-2 is over expressed in gastrointestinal neoplasm. Helicobacter pylori (H pylori) infection is causally linked to gastric cancer. However, the expression of COX-2 in various stages of H pylori-associated gastric carcinogenesis pathway has not been elucidated.
