[Gene methylation in stool for the screening of colorectal cancer and pre-malignant lesions].
To evaluate association between DNA methylation of MAL, CDKN2A, and MGMT in stool and development of colorectal cancer, and to evaluate the screening value of these biomarkers in colorectal cancer and pre-malignant lesions. ⋯ DNA methylations levels of MAL, CDKN2A, and MGMT in stools are significantly higher in colorectal cancer and colon adenoma, which may serve as an noninvasive approach for the screening of colorectal cancer and pre-malignant lesions.

Editorial[Necessity and feasibility of screening for colorectal cancer in China].
Incidence and mortality of colorectal cancer has increased significantly in recent years. Screening for colorectal cancer is the most effective method to decrease mortality. Colorectal adenoma is the precancerous lesion of colorectal cancer and can be detected through colonoscopy, which is the crucial in the early diagnosis and early treatment for colorectal cancer. ⋯ The selection of candidate for screening has direct effect on the efficacy of screening. The methods in common use include fecal occult blood test, questionnaire for high risk factors of colorectal cancer, colonoscopy, sigmoidoscopy, and CT virtual colonoscopy. Among those, colonoscopy is the most reliable method and widely used in the screening for colorectal cancer.

Editorial["Damage control surgery" concept in gastrointestinal surgery].
In recent years, damage control is well established as a potentially life-saving procedure in a few selected critically injured patients. The "damage control" concept also has been shown to increase overall survival and is likely to modify the management of critically ill patients suffering from gastrointestinal disease. In these patients the "lethal triad" of hypothermia, acidosis, and coagulopathy acts as a vicious cycle that often can not be interrupted and marks the limit of the patient's ability to cope with the physiological consequences of traditional and extensive surgical procedures. ⋯ During the initial operation, the surgeon carries out only the absolute minimum necessary to improve patient's condition and to control bleeding, obstruction, and/or infection. The second phase consists of secondary resuscitation in the intensive care unit, characterized by maximization of hemodynamics, correction of coagulopathy, rewarming, and complete ventilatory support. During the third phase, definitive operation is performed.
