Background: Although chronic erosive gastritis (CEG) is common, its clinical characteristics have not been fully elucidated. The lack of consensus regarding its treatment has resulted in varied treatment regimens.
Aim: To explore the clinical characteristics, treatment patterns, and short-term outcomes in CEG patients in China.
Gut microbiome is integral to the pathogenesis of ulcerative colitis. A novel probiotic Lactobacillus intestinalis (L. intestinalis) exerts a protective effect against dextran sodium sulfate-induced colitis in mice.
View Article and Find Full Text PDFImbalance of gut microbiota homeostasis is related to the occurrence of ulcerative colitis (UC), and probiotics are thought to modulate immune microenvironment and repair barrier function. Here, in order to reveal the interaction between UC and gut microbiota, we screened a new probiotic strain by 16S rRNA sequencing from Dextran Sulfate Sodium (DSS)-induced colitis mice, and explored the mechanism and clinical relevance. (), as a potential anti-inflammatory bacterium was decreased colonization in colitis mice.
View Article and Find Full Text PDFLong noncoding RNAs (lncRNAs) are emerging as a new class of important regulators of signal transduction in tissue homeostasis and cancer development. Liquid-liquid phase separation (LLPS) occurs in a wide range of biological processes, while its role in signal transduction remains largely undeciphered. In this study, we uncovered a lipid-associated lncRNA, small nucleolar RNA host gene 9 (SNHG9) as a tumor-promoting lncRNA driving liquid droplet formation of Large Tumor Suppressor Kinase 1 (LATS1) and inhibiting the Hippo pathway.

Runt-related transcription factor 3 (Runx3) is an important transcription factor that functions as a tumor suppressor in gastric cancer. Whether there is an interplay between LncRNAs and Runx3 remains unclear.

Lymphatic metastasis is commonly observed in gastric cancer (GC), but hematogenous metastasis is more likely responsible for the cancer-related mortality. Since Stephen Paget first introduced the "seed and soil hypothesis" a century ago, growing evidence recognizes that numerous essential secreted factors and signaling pathway effectors participate in the pre-metastatic niche formation and distant organ metastasis. The cross-talk between GC cells and surrounding microenvironment may consist of a series of interrelated steps, including epithelial mesenchymal transition, intravasation into blood vessels, circulating tumor cell translocation, and secondary organ metastasis.

Objective: To summarize the current evidence on the biomarkers associated with DNA methylation in the screening and diagnosis of colorectal cancer (CRC).
Methods: A literature search was conducted on the databases of PubMed and Web of Science to identify articles published from 1 January 2000 to 6 June 2015 with language striction. Stuides focusing on the association between noninvasive biomarkers indicating DNA methylation and CRC were included.
Aim: To investigate the performance of magnifying endoscopy with narrow-band imaging (ME-NBI) in the diagnosis of early gastric cancer (EGC).
Methods: Systematic literature searches were conducted until February 2014 in PubMed, EMBASE, Web of Science, Ovid, Scopus and the Cochrane Library databases by two independent reviewers. Meta-analysis was performed to calculate the pooled sensitivity, specificity and diagnostic odds ratio and to construct a summary receiver operating characteristic (ROC) curve.
Cytomegalovirus, regarded as a trigger of several autoimmune diseases, is an opportunistic pathogen. Patients with ulcerative colitis (UC) undergoing steroid treatment are susceptible to this infection. In the presence of cytomegalovirus, inflammation becomes more complex.

The diagnosis of pituitary dysfunction is very difficult in inpatients with liver cirrhosis, because the symptoms are intricate and similar. We here report a case of a male patient complaining of fatigue and anorexia for more than two years. On duration of hospital stay, hyponatremia was irreformable.

Objective: To determine DNA methylation status of ZIC1 and KLOTHO gene in colorectal carcinomas and its relationship with clinicopathological features of patients.
Methods: The mRNA expression of ZIC1 and KLOTHO genes in colorectal carcinomas was detected by real-time quantitative RT-PCR, and the promoter methylation status was detected by methylation specific PCR (MSP). The relationship of ZIC1 and KLOTHO methylation status with clinicopathological features of colorectal carcinoma was analyzed.
The potential anti-senescence gene Klotho (KL) has been recently found to participate in the progression of several different human cancers including breast, lung, and cervical cancer. In this current study, we identified KL as a candidate tumor suppressor gene silenced through promoter hypermethylation in colorectal cancer (CRC). KL gene expression is found to be absent or reduced in colon cancer cell lines (5/6, 83.

Objective: To investigate the effect of small interfering RNA on cell proliferation and apoptosis in gastric cancer cell lines with high expression of RegIα.
Methods: Total RNA was isolated from six gastric cancer cell lines,and the expression of RegI α mRNA was detected by RT-PCR. RegI α RNAi expression vector was constructed and stably transfected into MKN45 and AGS cells with high RegI α expression, empty-vector was used as control.

Objective: To construct RegIα over-expression vector and to evaluate the effect of RegIα on the proliferation and apoptosis of gastric cancer MKN28 cells in vitro.
Methods: Full sequence of RegIα cDNA was amplified from normal gastric tissue samples by RT-PCR and cloned into pIRES2-EGFP vector. RT-PCR and Western blot were performed to detect expression levels of RegIα in MKN28 cells.
Objective: To detect whether muscovite exerts its protective role in the progression of atrophic gastritis (AG) and evaluate the possible mechanism.
Methods: AG rats were established and then randomly divided into groups administrated with different doses of muscovite for 8 weeks. Histological changes in gastric antrum and the number of parietal cells, chief cells, and G/D cells were observed.
Background And Aims: The aim of this study was to investigate whether rectal administration of muscovite can ameliorate colonic inflammation in a rat model of experimental colitis, and its possible mechanism.
Methods: Female Sprague-Dawley (SD) rats with trinitrobenzene sulfonic acid (TNBS)-induced colitis were treated with rectal administration of muscovite or 5-aminosalicylic acid (5-ASA) daily for 14 days. The changes in body weight, macroscopic damage and histologic scores were subsequently evaluated.

As one of major epigenetic changes responsible for tumor suppressor gene inactivation in the development of cancer, promoter hypermethylation was proposed as a marker to define novel tumor suppressor genes. In the current study we identified ZIC1 (Zic family member 1, odd-paired Drosophila homolog) as a novel tumor suppressor gene silenced through promoter hypermethylation in gastric cancer, the second leading cause of cancer death worldwide. In all of gastric cancer cells lines examined, ZIC1 expression was downregulated and such downregulation was accompanied with the hypermethylation of ZIC1 promoter.

Several models of experimental ulcerative colitis have been reported previously. However, none of these models showed the optimum characteristics. Although dextran sulfate sodium-induced colitis results in inflammation resembling ulcerative colitis, an obvious obstacle is that dextran sulfate sodium is very expensive.
