研究目的: |
1. 证明 IBS-D 患者存在冷刺激所致的内脏超敏性; 2. 探讨 IBS-D 患者摄入冷食后腹痛的部位和严重程度与肠道 TRPA1 通道的表达水平的相关性; 3. 进一步阐明 TRPA1 通道介导 IBS-D 患者温度感知障碍导致腹痛的主导机制为外周敏化还是中枢敏化,及其可能的机制。 |
||||||||||||||||||||||
|
Objectives of Study: |
1. Prove that IBS-D patients have visceral hypersensitivity caused by cold stimuli; 2. Explore the relationship between the location and severity of abdominal pain in IBS-D patients after eating cold foods and the expression levels of TRPA1 channels in the gut; 3. Further clarify whether the main mechanism by which TRPA1 channels mediate temperature perception disorders leading to abdominal pain in IBS-D patients is peripheral sensitization or central sensitization, and its possible mechanism. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
在结肠镜检查前,采用电子数据记录表收集患者一般人口学信息(匿名化编号处理),并通过IBS-SSS、HADS量表和VAS评分分别采集疾病严重程度、焦虑抑郁状态及冷食后腹痛数据 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Before colonoscopy, an electronic data record form was used to collect general demographic information of the patients (anonymized by coding). Data on disease severity, anxiety and depression status, and post-cold food abdominal pain were collected using the IBS-SSS, HADS, and VAS scales, respectively. |
