まとめ
刺激性腸症候群 (IBS) の患者およびネズミの内臓過敏症を効果的に軽減します. この治療は腸内微生物群を調節し マスト細胞の活性化を阻害し 腸内バリア機能を改善します
科学分野:
- 胃腸内科
- 神経科学
- 統合医療
背景:
- 内臓過敏症 (VHS) は,刺激性腸症候群 (IBS) の痛みの主要な要因である.
- 電気治療 (EA) は,IBS 症状の緩和に 期待されているが,その根本的なメカニズムは十分に理解されていない.
- VHを調節するバリアオのアクポイントの役割は,さらなる調査を必要としています.
研究 の 目的:
- バリアオのアキュポイントでのEAがIBSにおける内臓過敏症を緩和するメカニズムを明らかにする.
- 腸内細菌群,マスト細胞活性化,神経信号伝達経路に対するEAの影響をIBSモデルで調査する.
主な方法:
- 40人のIBS患者とエセティック酸/抑制ストレス誘発のラットモデルを対象としたトランスレーション研究.
- 患者とネズミのバリアオの点での標準化されたEA治療;ネズミの偽治療.
- 腸内敏感性 (VAS,AWR),マスト細胞脱粒化 (ヒスタミン,SP),腸内バリアの整合性 (ZO-1,オクラジン),腸内微生物群組成 (16S rDNA),および神経経路 (TRPV1,MAPK) の評価
主要な成果:
- EAはIBS患者とネズミの両方の内臓過敏性を有意に減少させた.
- EA治療は腸内微生物の多様性を回復し,有益なバクテリアを増やし,病原生物を抑制しました.
- EAはマスト細胞の脱粒化を抑制し,腸のバリア機能を強化し,TRPV1/MAPKの信号伝達を調節し,ニューロン-マスト細胞の交信を妨害しました.
結論:
- 腸内微生物群,マスト細胞活性化,TRPV1媒介の神経信号をターゲットにすることで,バリアオのアクუპポイントでのEAは内臓過敏症を緩和します.
- これらの発見は,複数の病理的経路に対処するIBSの潜在的な非薬物療法としてEAを支持します.
- この研究は,複雑な腸-脳相互作用を調節する の治療的可能性を強調しています.

Irritable Bowel Syndrome I: Introduction
369
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

Drugs for Treatment of Diarrhea-Predominant IBS
292
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists
395
Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...

Drugs for Treatment of Constipation-Predominant IBS
326
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...
