The microflora is the important component of tongue coating besides the desquamated epithelial cells. Tongue coating microflora might be an important linkage between the modern medical research and the classic traditional Chinese medicine theory. Therefore, the present paper summarised the application value of tongue coating microflora in health and disease to enrich the scienti fic connotation of traditional Chinese medicine tongue diagnosis and promote the development of integration of traditional Chinese medicine and modern medicine.展开更多

By sequencing the V3-V4 region of the 16S rRNA, we investigated the microbial community structure and diversity on the tongue coating. <b>Results:</b> There was no significant difference in the microbial diversity on the tongue coating between the two groups. However, compared with the control, the atrophic gastritis group had a smaller number of operational taxonomic units (OTUs). At the class level, patients with atrophic gastritis had lower relative abundances of <i>Betaproteobacteria</i> and <i>Spirochaetia</i> than the control group. At the gene level, the abundance of <i>Neisseria</i> and <i>Aggregatibacter</i> in atrophic gastritis group had significantly decreased compared with control ones. Furthermore, functional prediction revealed that 24 metabolic pathways significantly differed between the two groups. <b>Conclusions:</b> Our findings provide novel evidence that tongue coating microbiota may be a biomarker for characterizing patient with atrophic gastritis, but its mechanism needs to be further elaborated.展开更多

However, the conventional method to examine the tongue lacks an acceptable standard and does not provide the means for sharing information. This paper describes a segmentation method to extract tongue coatings. First, the tongue body was extracted from the original image using the watershed transform. Then, a threshold method was applied to the image to eliminate the light from the camera flash. Finally, a threshold method using the Otsu model in combination with a splitting-merging method was used in the red, green, and blue (RGB) space to extract the thin coating. The combination of the above two methods is applied in the hue, saturation, and value (HSV) space to extract the thick coating. The feasibility of this method is tested by experiments, and the accuracy of segmentation is 95.9%.展开更多

Mechanism of the formation and change of tongue coating is an important scientific problem. In recent years, researches indicated that in addition to apoptosis related genes, epidermal growth factor(EGF) and epidermal growth factor receptor(EGFR) also contribute to tongue coating formation. In this paper, we summarized recent studies on the potential role of EGF and EGFR in regulating the formation of tongue coating to provide some reference for the further investigations on tongue coating formation mechanisms.展开更多
