ABSTRACT
Ulcerative colitis (UC) is a non-specific, chronic and relapsing intestinal inflammatory disease with unknown etiology. Biological agents had been used to treat UC, and efficacy was superior to traditional therapeutic drugs, however, many problems followed. This article reviewed the application of biological agents in the treatment of moderate-to-severe UC, therapeutic drug monitoring, special conditions occurred during the use of biological agents and their management.
ABSTRACT
Inflammatory bowel disease (IBD) is a chronic non-specific inflammatory digestive tract disease with unknown etiology. Patients with IBD are recommended to take life-long follow-up and treatment due to the long disease course and repeated recurrence of disease. With the development of ultrasound technology, trans-abdominal bowel ultrasound has been brought into focus in recent years because of its high sensitivity, specificity, free of radiation, convenience and economy. This article reviewed the characteristics of ultrasound of IBD and the application and value of trans-abdominal bowel ultrasound in IBD.
ABSTRACT
Inflammatory bowel disease(IBD)is a non-specific,chronic intestinal inflammatory disease,which mainly includes ulcerative colitis(UC)and Crohn's disease(CD). The pathogenesis of IBD is not completely clear,and is mainly related to gene,environment,dysfunction of immune system and intestinal mucosal barrier. As the first defense line of intestinal mucosal barrier,the mucus barrier plays an important role in the occurrence and development of IBD. This article reviewed the advances in study on mucus barrier in IBD.
ABSTRACT
Objective To investigate the effect of hemodialysis(HD) on the endothelial cells of the patients with end-stage renal disease(ESRD). Methods The study population consisted of 30 patients with undergoing first hemodialysis treatment and 20 healthy individuals from March to November of 2003.The number of circulating endothelial cells(CEC) and the concentration of von Willebrand factor(vWF) were measured in HD patients at predialysis,1h during HD,2h during HD,and the end of HD.CEC and vWF were observed in healthy subjects. Results CEC and vWF were increased in HD patients compared with healthy individuals,and elevated continuously during HD.Increased CEC and vWF were correlated significantly with duration of HD. Conclusion Endothelial cell dysfunction exists in the patients with ESRD.HD procedures may cause endothelial cell damage.
