Actions of the 5-HT(4) serotonergic receptor partial agonist, tegaserod, were investigated on mucosal secretion in the guinea-pig and human small intestine and on electrophysiological behaviour of secretomotor neurons in the guinea-pig small intestinal submucosal plexus. Expression of 5-HT(4) receptor protein and immunohistochemical localization of the(More)
BACKGROUND AND PURPOSE To test a hypothesis that: (i) duodenal pH and osmolarity are individually controlled at constant set points by negative feedback control centred in the enteric nervous system (ENS); (ii) the purinergic P2Y(1) receptor subtype is expressed by non-cholinergic secretomotor/vasodilator neurons, which represent the final common excitatory(More)
OBJECTIVES To report the clinical, laboratory, and histological characteristics in a cohort of 28 Chinese patients with immunoglobulin G4-related disease (IgG4-RD). METHOD The patients were admitted to, or were out-patients in, Peking Union Medical College Hospital (PUMCH) between January 2011 and May 2012 according to the criteria for IgG4-RD. Clinical(More)
Objective: To clarify the efficacy and safety of cyclosporine A (CsA) as salvage therapy in patients with severe active ulcerative colitis (UC) and refractory to steroids. Methods: A total of 24 severe active UC patients refractory to steroids and hospitalized from 2006 to 2012, were retrospectively enrolled.Data including demographic features, clinical(More)
Endothelin antagonists, novel tripeptides containing a series of unnatural amino acids, were synthesized and characterized. A linear peptide BQ-485, perhydroazepin-1-yl-L-leucyl (1)-D-tryptophanyl (2)-D-tryptophan (3), was selected as the parent compound. The introduction of D-Phe derivatives into these peptidic ET antagonists resulted in potent activity(More)
OBJECTIVE To investigate the bowel symptoms and psychological status of patients with irritable bowel syndrome (IBS) with diarrhea (IBS-D), and to verify whether sigmoid colon mucosal mast cells (MCs) and their activation have effect on the symptoms and psychological status of IBS-D patients. METHODS Patients meeting Rome Ⅲ diagnostic and subtyping(More)
