    ABSTRACT: This study was designed to demonstrate the safety and efficacy of esomeprazole combined with flupentixol/melitracen for the treatment of gastroesophageal reflux disease (GERD) patients with emotional disorders. METHODS Two hundred eighty-nine GERD patients with emotional disorders were divided randomly into two groups: group 1 received esomeprazole only (monotherapy) and group 2 received esomeprazole and flupentixol/melitracen (combination therapy). The patients' GERD questionnaire (GerdQ) and hospital anxiety and depression (HAD) scores were obtained before and after treatment. Changes in the scores, rates of symptom remission, and adverse effects were compared between the two groups.

    ABSTRACT: This single center, randomized, and controlled study aimed to compare the effectiveness and safety of polyethylene glycol electrolyte lavage (PEG-EL) solution and colonic hydrotherapy (CHT) for bowel preparation before colonoscopy. A total of 196 eligible outpatients scheduled for diagnostic colonoscopy were randomly assigned to the PEG-EL (n = 102) or CHT (n = 94) groups. Primary outcome measures included colonic cleanliness and adverse effects. Secondary outcome measures were patient satisfaction and preference, colonoscopic findings, ileocecal arrival rate, examiner satisfaction, and cecal intubation time. The results show that PEG-EL group was associated with significantly better colonic cleanliness than CHT group, fewer adverse effects, and increased examiner satisfaction. However, the CHT group had higher patient satisfaction and higher diverticulosis detection rates. Moreover, the results showed the same ileocecal arrival rate and patient preference between the two groups (P > 0.05). These findings indicate that PEG-EL is the preferred option in patients who followed the preparation instructions completely.

    ABSTRACT: BACKGROUND: To assess the diagnostic effectiveness, cardiopulmonary safety, and patient comfort of transnasal endoscopy (TNE), compared with conventional endoscopy (CES) and sedated endoscopy (SES), and to compare procedural risks and patient satisfaction/preference. METHODS: In this prospective, randomized, and controlled protocol, eligible patients (n = 397) in an outpatient clinic were randomized to CES (n = 133), SES (n = 134), or unsedated TNE (n = 130) due to upper gastrointestinal (GI) complaints. Patients were continuously monitored for systolic/diastolic blood pressure (SBP/DBP), pulse rate (PR), and SpO(2) throughout the endoscopy. All subjects (n = 392) completing their assigned endoscopy were asked to evaluate endoscopy satisfaction, pain, and nausea/vomiting on visual analog scales. Patient preference for the assigned endoscopy was assessed against previous endoscopy experience or by willingness to repeat the assigned endoscopy. RESULTS: Endoscopic outcomes for the esophagus, stomach, and duodenum were comparable among the three groups. SBP/DBP and PR were more stable in patients undergoing TNE than in those undergoing CES or SES, while SpO(2) remained stable and above 95 % among all three groups. Patients were more satisfied with TNE than with CES and experienced less pain and nausea/vomiting. Patients exhibited a high preference for SES, whereas 67.6 % of patients who previously underwent SES and were randomly assigned to TNE were willing to undergo TNE again. CONCLUSIONS: TNE has comparable diagnostic effectiveness to CES and SES, but is less stressful on cardiopulmonary function, indicating that TNE is a more comfortable, preferred, and cost-effective endoscopic technique than CES and SES.

    ABSTRACT: H. pylori interacts with gastric epithelial cells, which may activate signaling pathways important for gastric cancer invasion. Ezrin, a membrane cytoskeletal crosslinker protein, is well documented to regulate cell adhesion and cell motility. The aim of the present study was to determine whether ezrin is involved in H. pylori-induced cancer cell motility and invasion. The VIL-2 of RNA interference plasmid vector and control plasmid vector were constructed. AGS (a human gastric adenocarcinoma cell line) cells were transfected by these plasmid vectors. The stable expression cell lines AGS(ezrin) was obtained by G418 resistance screening. The express levels of ezrin protein and the cellular invasive potential of four groups, including the AGS control, AGS(ezrin) control, AGS co-culture with H. pylori, AGS(ezrin) co-culture with H. pylori were detected. Meanwhile, the morphology, cell migration and adhesion were determined respectively. Co-culture with H. pylori stimulated AGS cell motility and invasion, up-regulated ezrin expression at the protein level and induced a Hummingbird phenotype. The silencing of ezrin expression suppressed the motility and invasion of gastric cancer cells and inversed the cell invasion phenotype and enhanced the ability for cell adhesion. Knockdown of ezrin by RNAi suppresses H. pylori-enhanced migration and invasion of gastric cancer cells. These findings indicate that ezrin may play a key role in the migration and invasion of gastric cancer cells, and thus may be a therapeutic target to prevent metastasis of gastric cancer promoted by H. pylori infection.

    ABSTRACT: To clarify the role of the mitochondrial pathway in apoptosis induced by H. pylori infection in gastric epithelial cells. Cells of a gastric adenocarcinoma cell line SGC-7,901 were co-cultured with H. pylori NCTC 11,637, with or without preincubation with the inhibitors of caspases -3, -8, and -9. Apoptosis was determined by flow cytometry. RT-PCR was used to determine the expression of Bid, Bax, and Bcl-2 mRNA, and Western blotting was used to determine the expression of Bid, Bax, and Bcl-2 proteins, and the activation of caspases -3 and -9. H. pylori directly induced apoptosis in SGC-7,901 cells. Apoptotic indices (AIs) were 6.30 +/- 0.40%, 11.57 +/- 0.78%, 8.63 +/- 0.67%, and 7.22 +/- 0.97%, respectively, at 6, 12, 24, and 48 h after SGC-7,901 cells were co-cultured with H. pylori. H. pylori up-regulated the expression of Bid and Bax at both protein and mRNA levels, and induced a time-dependent activation of caspases -3 and -9. Apoptosis was inhibited significantly by the preincubation of SGC-7,901 cells with the inhibitors of caspase-3 (AIs were 1.72 +/- 0.59%, 2.97 +/- 0.55%, 4.38 +/- 1.56%, and 3.29 +/- 0.83%, respectively, at 6, 12, 24, and 48 h), and caspase -9 (AIs were 2.47 +/- 0.53%, 6.68 +/- 0.47%, 5.97 +/- 0.46%, and 5.43 +/- 0.15%, respectively, at 6, 12, 24, and 48 h). The caspase-8 inhibitor also reduced H. pylori-induced apoptosis by 20%. H. pylori infection induces apoptosis and the activation of caspases -3 and -9 in gastric cancer cells. Moreover, the caspase inhibitors significantly suppress H. pylori-induced apoptosis. These findings suggest that the mitochondrial pathway may be the major pathway in H. pylori-induced apoptosis in gastric epithelial cells.

    ABSTRACT: To explain the role of mitochondrial pathway in the apoptosis of SGC-7901 cell line induced by concentrated Helicobacter pylori culture supernatant (CHCS). Cytochrome oxidase (COX) I expression was detected by Western blotting. Cell apoptosis and mitochondrial membrane potential were measured by flow cytometry. CHCS could induce the apoptosis of SGC-7901 in a dose- and time-dependent manner. Apoptotic rates gradually enhanced followed by the concentrations increasing. The mitochondrial membrane potential (MMP) began to descend after treating CHCS for 4 h, and MMP descended most distinctly in 8 h. It descended the lowest point in 12 h, and it had no special changes in 24 h. The expression of COX I was notably lower than that of control group after CHCS treating (632.8 +/- 40.6 vs 895.1 +/- 44.2, P < 0.05). Mitochondrial pathway may play an important role in the apoptosis of SGC-7901 cells induced by CHCS.
