Association between tongue coating thickness and ultraviolet fluorescence in patients with functional dyspepsia

Abstract

The aim of this study was to examine the correlation between the tongue coating thickness (TCT) and ultraviolet (UV) fluorescence and propose a new method for the estimation of TCT using a computerized tongue image acquisition system (CTIS). In this prospective and observational single-center study, we acquired tongue images under visible light and near-UV light for 60 patients with functional dyspepsia. Tongue images were acquired twice within a 30-minute interval to assess the reliability of CTIS. Then, the tongue coating was scraped and weighed to derive the wet weight of the tongue coating (WWTC). The percentage of the tongue coating area was calculated from the tongue images acquired under visible light. Mean color values (mCVs) for the UV fluorescence of the dorsal surface of the tongue were also computed. The reliabilities of the derived mCVs and percentage of the tongue coating area were acceptable (intraclass correlation coefficients, 0.907–0.947). The mCVs were more strongly correlated with WWTC than with the area, with mCV of modified lightness showing the strongest association ( r = 0.785, P < .01). Finally, we suggested an estimation model for TCT based on the results. The results of this study suggest that both UV fluorescence of the dorsal tongue and the distribution area of tongue coating are useful parameters for the quantitative assessment of tongue coating. We believe that these findings will contribute to the development of a clinically useful CTIS.

Mosapride Citrate Combined with Divine Qu Disinfectant Oral Liquid for Children Function Dyspepsia and the Influence of Serum Factors

“…Long-term living and learning pressure, excessive psychological burden, etc., will lead to abnormal gastrointestinal hormone secretion and autonomic nervous dysfunction. In recent years, mosapride citrate tablets combined with Shenqu Xiaoshi oral liquid have been applied in children with functional dyspepsia, and the effect has been satisfactory [ 16 ]. In this study, the scores of abdominal distension, abdominal pain, lack of appetite, nausea and vomiting, irregular stool, and mental fatigue in the combined group were lower than those in the Western medicine group at 14 d after treatment ( p < 0.05), indicating that mosapride citrate tablet combined with Shenqu Xiaoshi oral liquid can reduce the score of functional dyspepsia in children, which is conducive to the recovery of children.…”
