Patients with IBD have increased risk for colorectal cancer. Because the pathogenesis of colorectal carcinoma has not been entirely defined yet and there is no ideal treatment for colon cancer, cancer prevention has become increasingly important in patients with IBD. The two adopted methods to prevent the development of colon cancer in clinical practice include the prophylactic colectomy and colonoscopic surveillance.But patients and physicians seldom accept colectomy as a routine preventive method and most patients do not undergo appropriate colonoscopic surveillance. Chemoprevention refers to the use of natural or synthetic chemical agents to reverse, suppress, or to delay the process of carcinogenesis.Chemoprevention is a particularly useful method in the management of patients at high risk for the development of specific cancers based on inborn genetic susceptibility, the presence of cancer-associated disease, or other known risk factors. Prevention of colorectal cancer by administration of chemopreventive agents is one of the most promising options for IBD patients who are at increased risks of the disease. The chemopreventive efficacy of nonsteroidal antiinflammatory drugs (NSAIDs) against intestinal tumors has been well established. But with reports that NSAIDs aggravated the symptoms of colitis, their sustained use for the purpose of cancer chemoprevention has been relatively contraindicated in IBD patients. Another hopeful candidate chemoprevention drug for IBD patients is 5-aminosalicylic acid (5-ASA), which is well tolerated by most patients and has limited systemic adverse effects, and no gastrointestinal toxicity. 5-ASA lacks the well-known side effects of longterm NSAIDs use. Retrospective correlative studies have suggested that the long-term use of 5-ASA in IBD patients may significantly reduce the risk of development of colorectal cancer. According to the literature, this agent might well satisfy clinical expectations with respect to a safe and effective chemopreventive agent. 展开更多

With the sustained and stable development of Chinas economy, the urbanization process is accelerating, and the number of construction projects in various regions has increased significantly. How to ensure the quality of construction projects is the problem that relevant institutions need to solve. Foundation is the foundation structure of construction engineering, and the deep foundation pit support construction can affect the overall quality of foundation construction, and then affect the stability and safety of construction engineering. Therefore, it is necessary to strengthen technical research, and take effective control measures. This paper analyzes and summarizes the construction technology and control measures of deep foundation pit support in construction engineering, and introduces engineering examples to explore the specific application methods of related technologies. 展开更多

Those who hardly know about Ding Ming might be likely to assume that Ding's works are much influenced by masters like Zhao Wuji.Picasso, Van Gogh and Joan Miro.Ding was unable to hear and speak due to illness since his childhood.Living in the out-of-the-way comtryside.he barely knew about great artists and their works when he started his painting carreer at the age of 11. Therefore many people believe that Ding observes the world in a way similar to that of the masters. 展开更多
