RESUMEN
According to traditional Chinese medicine theory, tongue coatings reflect changes in the body. The goal of this study was to identify a metabolite or a set of metabolites capable of classifying characteristics of traditional Chinese medicine syndromes in erosive gastritis. In this study, we collected tongue coatings of patients with erosive gastritis with damp-heat syndrome (DHS), liver depression and qi stagnation syndrome (LDQSS), and healthy volunteers. Then, we analyzed the differences in metabolic characteristics between the two groups based on metabolomics. We identified 14 potential biomarkers related to the DHS group, and six metabolic pathways were enriched. The differential pathways included pyrimidine metabolism, pantothenate and CoA biosynthesis, citrate cycle (TCA cycle), pyruvate metabolism, glycolysis/gluconeogenesis, and purine metabolism. Similarly, in the LDQSS group, we identified 25 potential biomarkers and 18 metabolic pathways were enriched. The top five pathways were the TCA cycle, sphingolipid metabolism, fatty acid biosynthesis, pantothenate and CoA biosynthesis, and the pentose phosphate pathway. In conclusion, the DHS group and the LDQSS group have different characteristics.
RESUMEN
Objective To investigate the effects of anxiety ,depression and life events on patients with non-erosive gastroesophageal reflux disease (NERD) .Methods From November 2016 to December 2017 ,at The First Affiliated Hospital of the Medical College ,Shihezi University ,135 patients with NERD (NERD group) and 133 volunteers who received physical examination at the same period were enrolled (healthy control group) .The scores of self-rating anxiety scale (SAS) ,self-rating depression scale (SDS ) ,life event scale (LES ) and gastroesophageal reflux disease questionnaire (GerdQ ) of the enrolled individuals were obtained by questionnaire .Mann-Whitney ranking test ,chi square test and Spearman rank correlation test were performed for statistical analysis .Results The patients with anxiety in NERD group accounted for 46 .67％ (63/135) ,which was higher than that in healthy control group (1 .50％ ,2/133) ,and the difference was statistically significant (χ2 =74 .38 , P< 0 .01) .The patients with depression in NERD group accounted for 12 .59％ (17/135) ,which was higher than that of healthy control group (0 ,0/133) ,and the difference was statistically significant (χ2 = 17 .88 ,P< 0 .01) .The SAS score of NERD group was 48 points (45 points ,52 points) ,which was higher than that of healthy control group (37 points (33 points ,43 points)) ,and the difference was statistically significant (Z=-11 .03 ,P<0 .01) .The SDS score of NERD group was 46 points (41 points ,50 points) ,which was higher than that of healthy control group (36 points ,32 points to 40 points) ,and the difference was statistically significant (Z= -11 .03 , P<0 .01) .The LES score of NERD group was 32 points (10 points ,45 points) , which was higher than that of healthy control group (3 points ,0 points to 32 points) ,and the difference was statistically significant (Z= -2 .18 ,P=0 .03) .The score of LES negative events in NERD group was 21 points (3 points ,36 points) ,which was higher than that of the healthy control group (0 points ,0 points to 23 points) , and the difference was statistically significant (Z= -2 .19 , P=0 .03) .GerdQ score was positively correlated with SAS ,SDS ,LES scores and LES negative event score ,and the differences were all statistically significant (r=0 .65 ,0 .60 ,0 .29 and 0 .29 ,all P< 0 .05) .Conclusions Anxiety ,depression and life events are the influencing factors of NERD .The greater the impact of anxiety ,depression and life event (especially negative live events) ,the more severe the NERD symptoms .
