Context: Colorectal neoplasm and coronary artery disease (CAD) share similar risk factors, and their co-occurrence may be associated.

Objectives: To investigate the prevalence of colorectal neoplasm in patients with CAD in a cross-sectional study and to identify the predisposing factors for the association of the 2 diseases.

Design, Setting, And Participants: Patients in Hong Kong, China, were recruited for screening colonoscopy after undergoing coronary angiography for suspected CAD during November 2004 to June 2006.

Background: Both serum IL-6 levels and CpG island methylation have been shown to have prognostic significance in gastric cancer, it was suggested that an important link existed between IL-6 and methylation of cancers.

Aim: To investigate the prognostic value of IL-6 serum level and the association between serum IL-6 levels and CpG island methylation at p16, DAPK, MGMT and E-cadherin in patients with gastric cancer.

Patients And Methods: Methylation status was assessed by MSP in 75 surgical specimens of gastric adenocarcinoma.

Background And Aims: The role of clopidogrel in patients at risk for gastrointestinal complications is uncertain, although it has been recommended for patients who have gastrointestinal intolerance to aspirin. We tested the hypothesis that clopidogrel is as effective as esomeprazole and aspirin in preventing recurrences of ulcer complications.

Methods: This was a prospective, double-blind, randomized, controlled study of 170 patients who developed ulcer bleeding after the use of low-dose aspirin between November 2002 and January 2005.

Purpose: Selective cyclooxygenase-2 (COX-2) inhibitors cause significantly fewer peptic ulcers than conventional nonselective nonsteroidal anti-inflammatory drugs (NSAIDs) in patients at low risk or high risk for peptic ulcers. On the other hand, proton pump inhibitor co-therapy has also been shown to be effective in preventing relapse of peptic ulcers in high-risk patients using nonselective NSAIDs. We compared the efficacy of a selective COX-2 inhibitor with that of proton pump inhibitor co-therapy in the reduction in the incidence of ulcer relapse in patients with a history of NSAID-related peptic ulcers.

Background And Aims: Transient lower esophageal sphincter relaxation (TLESR) is the major mechanism for gastroesophageal reflux in the Western population. The major reflux mechanism in Chinese patients with GERD has not been studied before.

Methods: Fifty-four patients with GERD and 28 controls underwent stationary baseline manometry and the 24-h ambulatory esophageal pH monitoring.

Aim: Population-based assessment of noncardiac chest pain (NCCP) is lacking. The aim of this study was to evaluate the prevalence, psychosocial factors and health seeking behaviour of NCCP in southern Chinese.

Methods: A total of 2 209 ethnic Hong Kong Chinese households were recruited to participate in a telephone survey to study the epidemiology of NCCP using the Rose angina questionnaire, a validated gastroesophageal reflux disease (GERD) questionnaire and the hospital anxiety-depression scale.

Purpose: To evaluate whether pretherapeutic serum soluble E-cadherin is an independent factor predicting long-term survival in gastric cancer. Gastric cancer remains the second leading cause of cancer-related deaths in the world, but a satisfactory tumor marker is currently unavailable for gastric cancer. Soluble E-cadherin has recently been found to have prognostic value in gastric cancer.

Objective: This study sought to explore some psychosocial factors that distinguished individuals with noncardiac chest pain (NCCP) from those without NCCP, and whether these psychosocial factors were associated with anxiety and depression that are co-morbid factors of NCCP.

Methods: A matched case-control design was adopted to compare differences in psychosocial factors among a target group of patients with NCCP (N = 70), a pain control group of patients with rheumatism (N = 70), and a community control group of healthy individuals (N = 70).

Results: Compared with subjects from the two control groups, NCCP patients tended to monitor more, use more problem-focused coping, display a coping pattern with a poorer strategy-situation fit, and receive less emotional support in times of stress.

Background And Aim: Decrease in expression of the E-cadherin-catenin complex is an important element in gastric carcinogenesis. However, the expression of the complex in gastric precancerous lesions has not been well studied. The present study aimed to examine the serial change in expression of E-cadherin-catenin complex in the precancerous lesions of gastric cancer patients.

Objective: This study examined how patients with functional dyspepsia (FD) and duodenal ulcer (DU) coped with first-time endoscopy, a highly relevant real-life stressor. We adopted an observational method to enhance the ecological validity of the study on stress and coping.

Methods: A matched case-control design was adopted to compare differences between 30 Chinese FD patients from a select sample and 30 Chinese DU patients (13 females and 17 males in each group) in observed coping behaviors, mood states, and subjective appraisals of endoscopy.
