Abstract: An intestinal microorganism metagenomic feature is a bacteroid intestinal pattern. By using the intestinal metagenomic pattern, it was found that type 2 diabetic patients with different intestinal parasitic bacterial flora had remarkably different responses to treatment with the diabetic hypoglycemic drug acarbose. Therefore, before treatments, the intestinal patterns of the patients can be assessed to select those patients likely to experience optimal curative effects, and to determine whether acarbose is suitable for the treatment of individual patients with type 2 diabetes. In addition, while intestinal patterns are conventionally distinguished by DNA sequencing or PCT amplification of parasitic bacteria in excrements, the intestinal patterns can be well distinguished using a bile acid composition, especially secondary bile acids, under baseline conditions. The intestinal patterns can be identified through markers in blood, and then be used as markers for diagnosis.
