Irritable Bowel Syndrome
Conditions
Keywords
IBS, Ionotropic glutamate receptors
Brief summary
The study aims to determine the expression of the ionotropic glutamate receptors in colon of irritable bowel syndrome (IBS) patients and evaluate the relationship between the ionotropic glutamate receptors and IBS symptoms.
Detailed description
Ionotropic glutamate receptors participate in pain in nervous system. In this study,participants will examine the expression of the ionotropic glutamate receptors in colon of irritable bowel syndrome (IBS) patients and evaluate the relationship between the ionotropic glutamate receptors and IBS symptoms. Participants may futher study the mechanism using cell experiment.
Interventions
Patients will undergo colonoscopy and participants will get biopsies from the colon.

Eligibility
Inclusion criteria
Patients meeting IBS Rome III criteria. Asymptomatic individuals for health surveillance or patients for follow up after polypectomy.
Exclusion criteria
Patients with known cancers or abdominal surgery. Alarm symptoms such as anaemia, gastrointestinal bleeding or obstruction, marked weight loss, abdominal mass. Patients who are unwilling to sign or give the informed consent form. Patients with impaired cardiac, liver or renal function. Patients with coagulopathy. Patients with pregnancy or breastfeeding.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| the expression of the ionotropic glutamate receptors | 4 months | Participants will examine the expression level of ionotropic glutamate receptors using quantitative real-time RT-PCR and western blot ,examine the distribution using immunohistochemy. |
| the relationship between the ionotropic glutamate receptors and IBS symptom | 6 months | Symptoms will be assessed though the severity of abdominal pain or discomfort and seizure frequency.Participants will evaluate the relationship between the expression level or the distribution of ionotropic glutamate receptors and IBS symptom. If there is a link between them, participants will study the underlying molecular mechanisms. |
