研究目的: |
肠易激综合征(Irritable bowel syndrome, IBS)是一种最常见的功能性胃肠病之一,也是消化科的常见疾病,其主要特征是在无可见结构异常的情况下反复出现腹痛伴排便习惯改变[1]。全球流行病学研究表明,IBS的全球总体患病率约为4.1%[2]。各个国家和地区的患病率存在较大差异,一项基于中国、日本和韩国的流行病学调查显示,三个国家的IBS患病率分别约5.5%,14.9%和15.6%[3]。IBS病程长,可能反复发作,可显著降低患者生活质量和工作效率,并可能导致焦虑、抑郁等心理负担,同时明显增加了社会的医疗资源消耗和经济负担。根据功能性胃肠病的罗马IV标准,IBS 可分为便秘型(IBS-C)、腹泻型(IBS-D)、混合型(IBS-M)及未分型(IBS-U),既往研究显示,IBS-D是最常见的亚型,约占全部IBS患者的31.5%[4,5]。此外,IBS-D患者因同时伴随反复腹痛与频繁腹泻,通常表现出更为严重的症状。 IBS的病理生理学机制尚不完全清楚,但目前认为脑-肠轴交互的功能紊乱导致胃肠道动力障碍、内脏高敏感和中枢神经系统处理异常是IBS最重要的发病机制。此外,还可能包括遗传相关、肠道微生态失衡、肠道通透性异常、粘膜免疫功能紊乱等[6]。目前针对IBS-D的治疗包括健康教育、饮食干预、药物治疗和心理治疗,主要以缓解症状和改善生活质量为目标。然而,许多患者的治疗效果仍不理想,症状容易反复发作。此外,药物治疗往往针对IBS的其中一种症状,作用有限而且其副作用可能导致治疗过程中的矛盾。例如,止泻药洛哌丁胺可有效减少大便次数、改善稀便,但对腹痛几乎无作用,且可能导致便秘、腹胀等不良反应;解痉药可缓解腹部绞痛,但由于其抗胆碱能作用,使用过程中常出现口干、头晕、尿潴留及便秘等症状;三环类抗抑郁药等中枢性神经调节剂虽然在改善IBS的整体症状方面具有中等强度的证据支持,但其镇静、抗胆碱能副作用以及耐受性问题,明显限制了在日常临床实践中的长期应用[7-9]。 神经调节(neuromodulation)作为一种新兴的治疗方式,是通过电、磁、化学刺激及光遗传学等方式作用于中枢、自主或外周神经系统,从而调控神经活动。神经调节包括侵入式神经调节和非侵入式神经调节技术,已有多种方式被FDA(美国食品药品监督管理局)批准用于临床,例如迷走神经刺激(VNS)被用于治疗癫痫和抑郁症;深部脑刺激(DBS)应用于强迫症以及包括帕金森病在内的运动障碍;骶神经刺激(SNS)用于治疗盆底疾病和大小便失禁等[10-13]。 经皮神经电刺激(Transcutaneous electrical acustimulation, TEA)是一种常用的非侵入性的神经调节技术,通过体表电极传递低频脉冲电流刺激位于特定穴位的浅表外周神经,最常选择的穴位包括PC6(内关)和ST36(足三里)。TEA已被证实对胃食管反流、功能性消化不良、胃轻瘫、便秘及IBS等多种胃肠道疾病有良好的疗效[14-18]。机制研究显示,TEA可增强迷走神经传出活动、抑制交感过度兴奋、降低内脏传入敏感性、调节中枢痛觉加工网络,并减轻炎症信号[10],这些均与IBS-D的病理生理机制密切相关。且TEA使用体表电极刺激外周神经,替代了传统的电针或针灸的方法,更加安全、便捷,患者可居家自行操作。目前尚缺乏大规模及多中心的临床研究证实TEA在IBS-D患者中的疗效。 |

Objectives of Study: |
Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorders and a frequent condition encountered in gastroenterology practice. It is characterized by recurrent abdominal pain associated with changes in bowel habits in the absence of identifiable structural abnormalities [1]. Global epidemiological studies indicate that the overall prevalence of IBS is approximately 4.1% worldwide [2]. However, the prevalence varies substantially across different countries and regions. An epidemiological survey conducted in China, Japan, and South Korea reported IBS prevalence rates of approximately 5.5%, 14.9%, and 15.6%, respectively [3]. IBS is typically a chronic condition with a relapsing course, which can significantly impair patients’ quality of life and work productivity, and may lead to psychological burdens such as anxiety and depression. In addition, it imposes a considerable burden on healthcare resources and societal economic costs.According to the Rome IV criteria for functional gastrointestinal disorders, IBS can be classified into four subtypes: constipation-predominant (IBS-C), diarrhea-predominant (IBS-D), mixed type (IBS-M), and unclassified type (IBS-U). Previous studies have shown that IBS-D is the most common subtype, accounting for approximately 31.5% of all IBS cases [4,5]. Moreover, patients with IBS-D often experience both recurrent abdominal pain and frequent diarrhea, and therefore tend to present with more severe symptoms.The |

随机方法(请说明由何人用什么方法产生随机序列): |
受试者将按照1:1的比例随机分配至TEA组或假TEA组。随机化将按照研究中心进行分层。对于每个中心,由独立统计学专家使用计算机生成的随机序列表进行随机分配,采用固定区组大小为4的区组随机化方法,每个区组中包含2个TEA和2个假TEA的分配顺序,并以随机顺序排列。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Patients will be randomized in a 1:1 ratio to the TEA group or the sham TEA group. Randomization will be stratified by study center. For each center, an independent statistician will generate a computer-generated randomization list using permuted blocks with a fixed block size of 4, with two assignments to TEA and two to sham TEA in each block arranged in a random order. Eligible subjects will be assigned the next available randomization number in numerical order within their center. Investigators are not permitted to alter, skip, or select randomization numbers. |

盲法: |
由于 TEA 与假 TEA 的刺激部位不同,实施治疗的研究人员将知晓受试者的分组情况。然而,所有受试者、结局评估人员以及数据分析人员均保持盲法。实施干预的人员知晓分组,但受试者、结局评估人员和数据分析者保持盲法,以降低观察者偏倚和测量偏倚。设备为各单位既有库存,无厂家专门为本研究更改结构或包装。对照组采用同型号仪器,但电极贴于非穴位区域,并给予不产生生理效应的对照刺激(假刺激),外观和操作方式与 TEA 组一致,以维持盲法并减少安慰剂效应 |
|
Blinding: |
Because the stimulation sites of TEA and fake TEA are different, the researchers implementing the treatment will be aware of the grouping of the subjects. However, all subjects, outcome assessors and data analysts remained blinded. The personnel implementing the intervention were aware of the grouping, but the subjects, outcome assessors, and data analysts remained blinded to reduce observer bias and measurement bias. The equipment is in the existing inventory of each unit. No manufacturer has specially modified the structure or packaging for this research. The control group was equipped with the same model of instrument, but the electrodes were attached to non-acupoint areas, and a control stimulus (false stimulus) that did not produce physiological effects was given. The appearance and operation methods were consistent with those of the TEA group to maintain blinding and reduce the placebo effect |
