【摘要】 功能性便秘(FC)是一種原發并且持續性的便秘,是由各種因素引起的,如生活方式的改變、情緒低下、飲食方式不健康等。對于FC,目前的治療方法很多,但沒有一種方法能通用到所有病例,便秘的發生機制還不明確。最近的研究表明,腸道菌群與FC二者有著密不可分的聯系,腸道菌群紊亂可能促進便秘的發生發展。而益生菌能促進腸道菌群恢復平衡,從而達到對FC的治療作用。本文結合國內外相關研究成果,介紹了腸道菌群的改變、便秘與菌群改變的相關機制、改善腸道菌群的常用方法及合生元的治療等方面,闡述腸道菌群失調與FC之間的研究進展。

Research Progress on Intestinal Flora Characteristics and Biostime Therapy in Patients with Functional Constipation/LI Weichao, LIU Chunyuan, GAO Zhaowei, ZHAO Feng. //Medical Innovation of China, 2024, 21(02): -179
[Abstract] Functional constipation (FC) is a primary and persistent form of constipation that is caused by a variety of factors, such as lifestyle changes, low mood, and an unhealthy diet. For FC, there are many treatment methods, but no one method can be universal to all cases, and the mechanism of constipation is not clear. Recent studies have shown that intestinal flora is closely related to FC, and intestinal flora disturbance may promote the occurrence and development of constipation. Probiotics can promote intestinal flora to restore balance, so as to achieve the therapeutic effect of FC. Based on the relevant research results at home and abroad, this paper introduces the changes of intestinal flora, the related mechanisms of constipation and microbial flora changes, the common methods to improve intestinal flora and the treatment of Biostime, and expounds the research progress on the relationship between intestinal flora disorders and FC.

功能性便秘(FC)屬于功能性腸病之一,發病無明顯的腸道及全身器質性病變,其確切的病因目前仍知之甚少。其診斷主要依賴于患者在平常生活中排便時的感覺和臨床表現。目前FC的診斷依據是最新羅馬Ⅳ標準,根據羅馬Ⅳ診斷標準,FC必須符合下述2點或2點以上:(1)超過1/4的排便存在費力感;超過1/4的排便有不凈感;超過1/4的排便為塊狀便或硬便;超過1/4的排便有直腸、肛門梗阻感/阻塞感;超過1/4的排便需以手法幫助;每周自發排便不超過3次,癥狀出現至少6個月,且近3個月持續存在;(2)不用瀉藥幾乎不排稀便;(3)且不符合腸易激綜合征(IBS)的診斷標準[1]。相比于先前羅馬Ⅲ標準,羅馬Ⅳ對FC的診斷顯得更加科學、嚴謹,治療方案也更加趨于合理、規范。大量的臨床研究表明,在治療FC患者的過程中,調節腸道菌群能有效改善FC患者的癥狀[2]。……
