本文对34例腹泻型肠激惹综合征粪便中常见的9种厌氧、需氧菌进行了定量分析,结果证实这类患者肠道存在着菌群失调,以类杆菌、双歧杆菌、肠杆菌明显减少为主(P<0.01),经菌群调整治疗有效。文章提出,尽管这种肠道菌群的改变为原发或继发尚难肯定,但它的存在应引起我们的高度重视。 In this paper, 34 cases of diarrhea-predominant irritable bowel syndrome in feces of 9 kinds of anaerobic aerobic bacteria were quantitatively analyzed, the results confirmed that such patients with intestinal flora dysbacteriosis, Bacteroides, Bifidobacterium, intestinal Bacilli significantly reduced (P <0.01), adjusted by the flora effective treatment. The article suggests that although this change in gut flora is still difficult to identify as primary or secondary, its existence should arouse our attention.
