Methods:
Patients with dry eye who were treated in the Ophthalmology Ward and Outpatient Department of the First Hospital of Hunan University of Chinese Medicine from October 1, 2020, to October 30, 2021 were enrolled as the research participants in the study. They were assigned to two groups based on traditional Chinese medicine (TCM) syndrome types: heat stagnation in liver meridian pattern group and Qi-Yin deficiency pattern group. Healthy volunteers who underwent health check-ups in the Health Management Department were included as healthy group following the random number table method. The tears of the patients and the healthy volunteer participants were tested by high-performance liquid chromatography-mass spectrometry (LC-MS). The differential metabolites were screened out by multivariate statistical analysis, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment was performed on the differential metabolites. Finally, the association analysis of differential proteins and metabolites was conducted to verify and supplement the metabolites.
Results:
A total of 32 dry eye patients were enrolled, including 16 cases with heat stagnation in liver meridian pattern and 16 cases with Qi-Yin deficiency pattern. Fourteen healthy volunteers were included as healthy group. There were no significant differences in baseline characteristics among the three groups (P > 0.05). A total of 412 biomarkers were determined in Qi-Yin deficiency pattern group, mainly including lipids, lipid-like molecules, organic acids and their derivatives, organic heterocyclic compounds, and nucleosides and their analogues. For heat stagnation in liver meridian pattern group, 112 metabolites were determined, mainly including organic acids and their derivatives, lipids, and lipid-like molecules. The KEGG enrichment results of pathways and the relative content analysis of differential markers demonstrate that purine metabolism and caffeine metabolism pathways are common metabolic characteristics of all dry eyes. Among them, deoxyinosine monophosphate (dIMP) and 2-(formamido)-N1-(5-phospha-D-ribosyl) acetamidine can serve as their biomarkers. The main characteristics of Qi-Yin deficiency syndrome pattern were the significant enhancement of metabolic pathways such as lysine degradation, ovarian steroidogenesis, cholesterol metabolism, pyrimidine metabolism, and bile secretion (P < 0.05). Dry eye associated with the heat stagnation in liver meridian pattern is mainly characterized by inhibition of the valine, leucine, and isoleucine biosynthesis pathways (P < 0.05).
Conclusion
Metabolomics can be used as an effective basis for TCM syndrome classification. Different patterns of dry eye syndrome exhibit typical characteristics in the types and concentrations of metabolites, which correspond to the syndrome classification in TCM. This study initially confirms the rationality of TCM syndrome classification and provides significant reference for the mechanism of dry eye and drug development.

Malignancies are diseases resulting from an imbalance of cell growth and proliferation, endangering human health and life. Currently, there is no clinically effective treatment for tumors. Tumor cells may alter cell adhesion and tumor cell migration and movement by degrading the extracellular matrix, generating vascular factors, affecting epithelial-mesenchymal transformation, or altering the tumor microenvironment. The mechanisms which lead to multidrug resistance (MDR) are the regulation of membrane proteins, apoptosis-regulated gene expression, enzyme-mediated multidrug resistance, DNA damage repair, and epithelial-stromal transformation, resulting in ineffective treatment of tumors. Therefore, the search for natural, safe, and effective chemosensitizers has become a critical part in tumor research. Due to the increasing use of Chinese medicine in cancer treatment, researchers have conducted more extensive studies on its monomers and compounds. In addition, the mechanisms of Chinese medicine in inhibiting tumor invasion and metastasis and reversing drug resistance are gradually unraveled. The monomers and compounds of Chinese medicine may inhibit tumor invasion, metastasis, and drug resistance by enhancing the sensitivity of chemotherapy drugs and adjuvant properties. Furthermore, they can also improve the tolerance of patients to chemotherapy drugs, relieve side effects of chemotherapy, reduce the chance of recurrence, and prolong the life of patients. The development of traditional Chinese medicine plays an important role in reducing tumor recurrence and metastasis, reversing drug resistance, prolonging the prognosis of cancer patients, improving their quality of life, and prolonging their survival time. Currently, various types of Chinese medicines have been proven to be capable of reducing tumor invasion and metastasis, and reversing drug resistance. The present article reviewed development and findings of Chinese medicine as an anti-tumor invasion, anti-metastasis, and anti-tumor resistance therapy in recent years, in order to provide ideas for future research on anti-tumor effect of active components in Chinese medicine.
