研究设计:

病例对照研究 

Study design:

Case-Control study 

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.

Inclusion criteria

排除标准:

Exclusion criteria:

1. History of abdominal surgery or trauma; 2. History of intestinal vascular diseases; 3. Use of antibiotics, gastrointestinal prokinetic agents, or drugs that may affect TRPA1 function (such as capsaicin, non-steroidal anti-inflammatory drugs, certain calcium channel antagonists, etc.) within one month prior to enrollment; 4. Organic lesions of the intestinal mucosa detected by colonoscopy; 5. Pregnant women; 6. Patients with severe cardiac, pulmonary, or renal systemic diseases.

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.
