RESUMO
OBJECTIVE: To summarize current hotspots and predict the potential trends in traditional drugs of diabetes treatment for further research. METHODS: Publications on the application of traditional drugs in diabetes treatment were searched from PubMed without language limits. Highly frequent MeSH terms were identified through Bibliographic Item Co-Occurrence Matrix Builder (BICOMB). Biclustering analysis results were visualized utilizing the gCLUTO software. Finally, a strategic diagram was generated. RESULTS: Totally 2,386 relevant publications were obtained from PubMed on November 9th, 2018, and 69 highly frequent MeSH terms were identified. Biclustering analysis revealed that these highly frequent MeSH terms were classified into 7 clusters. After calculating the density and centrality of each cluster, strategy diagram was presented. Cluster 0 "Chinese medicine monomers such as antioxidant and hypoglycemic effects" was considered as the most potential research hotspot. CONCLUSIONS: In this study, we found 7 topics related to the application of traditional drugs in diabetes treatment. The molecular mechanisms of Chinese medicine monomers in diabetes could become a potential hotspot with high centricity and low density.

Previous studies suggested the potential associations of trimethylamine N-oxide (TMAO) and its metabolic precursor l-carnitine with obesity. However, existing evidence is limited and inconsistent. In the present study, we perform a cross-sectional analysis of the associations of serum levels of TMAO and l-carnitine with obesity measures, including BMI, body fat distribution and body composition in 1081 participants from the general Newfoundland population. The dietary effects of TMAO and l-carnitine in preventing high fat diet-induced obesity in both male and female mice were also evaluated. We found significant associations between higher serum l-carnitine levels and obesity (higher BMI, body fat mass and VT%) in women, but not in men after controlling multiple confounding factors. Serum TMAO levels were positively associated with age, but not obesity in both men and women. Dietary TMAO had no influence on fat accumulation in high fat diet-fed mice. However, l-carnitine supplementation prevented high fat diet-fed induced obesity in both male and female mice by up-regulating lipolysis and down-regulating lipogenesis in white adipose tissues. The present study provides further evidence for the relationships between TMAO, l-carnitine and obesity.
