To explore the potential molecular mechanism of complex rose-bergamot essential oil on anti-anxiety with facial spots based on network pharmacology.

OBJECTIVE: To explore the potential mechanism of complex rose-bergamot essential oil against anxiety accompanied with facial spots through network pharmacology. METHODS: The components of rose and bergamot essential oils were determined by GC-MS and obtained from literature, and their action targets were predicted by PubChem, SwissADME and SwissTargetPrediction databases. Using "Anxiety disorder" and "Facial pigmentation" as keywords, the relevant targets of anxiety disorder and facial spots were mined in the databases of DrugBank, TTD, GeneCards, and OMIM. The intersection targets of complex rose-bergamot essential oil and anxiety accompanied with facial spots diseases were obtained by making Venn diagram, respectively. Protein-protein interaction (PPI), Gene Ontology (GO), and Kyoto Encyclopedia of genes and genomes (KEGG) pathway enrichment analysis of intersection targets were carried out through STRING platform, Metascape, and KEGG Mapper databases. The "complex essential oil- component- target- pathway" network was constructed by Cytoscape software. The key active compounds and core targets were docked by AutoDock software. RESULTS: A total of 34 active components of complex rose-bergamot essential oil and 405 corresponding targets were obtained. The intersection targets of complex essential oil with anxiety disorder and facial spot were 88 and 34, respectively, and the related KEGG pathways were 137 and 123 items, respectively. Neroli acetate, Neroli alcohol, and Linalool in complex rose-bergamot essential oil could play a therapeutic role in anxiety disorder by regulating key targets such as SLC6A4, GRIN2B and DRD2 to participate in the neuroactive ligand-receptor interaction and serotonergic synapse and other pathways, they also could play a role in the treatment of facial spots by regulating key targets such as EGFR, VEGFA, and PIK3CA in the PI3K-AKT, JAK-STAT and other signal pathways. The molecular docking between the key compounds and the core targets showed that the binding energy was less than 0 kcal /mol, indicating that the compound and the target could bind stably. CONCLUSION: Complex rose-bergamot essential oil can play a role in the treatment of anxiety disorder with facial spots through the synergistic mechanism of multicomponent, multitarget, and multipathway.

The value of enhanced computed tomography-based nomograph model in the differential diagnosis of gastric schwannoma and gastric stromal tumor / 中华消化杂志

Objective:To construct enhanced computed tomography (CT)-based nomograph model, to assist physicians in differentiating gastric schwannoma from gastric stromal tumor.Methods:From January 1, 2012 to January 1, 2022, at the Second Affiliated Hospital of Zhejiang University School of Medicine and Ningbo Hwamei Hospital, University of Chinese Academy of Sciences, 57 patients with gastric schwannoma and 275 patients with gastric stromal tumor confirmed by surgical pathology were retrospectively collected, among whom 39 patients with gastric schwannoma and 201 patients with gastric stromal tumor were enrolled in the training set, and the other 18 patients with gastric schwannoma and 74 patients with gastric stromal tumor were enrolled in the validation set. The contrast-enhanced CT imaging features (tumor size index, arterial phase CT value, venous phase CT value, necrosis, calcification, integrity of mucosal surface, and uniform enhancement, etc.) and clinical data (history of gastritis, carbohydrate antigen 19-9 (CA19-9), carcinoembryonic antigen, and monocyte to lymphocyte ratio (MLR), etc.) were collected. The least absolute shrinkage and selection operator (LASSO) regression analysis was used to screen the independent predictive factors of imaging features in the differential diagnosis of gastric schwannoma and gastric stromal tumor, and a nomograph model was constracted. Logistic regression analysis was used to analyze and screen the independent predictive factors of clinical indicators to distinguish gastric schwannoma from gastric stromal tumor, and a clinical control model was established. The receiver operating characteristic curve(ROC) was used to analyze the area under the curve (AUC) of the nomograph model in the training set and the verification set, and concordance index (CI) and decision curve analysis (DCA) were used to evaluate the predictive efficiency and clinical application value of the nomograph model. DeLong test was used for statistical analysis.Results:The results of LASSO regression analysis showed that tumor size index, arterial phase CT value, venous phase CT value, necrosis, calcification, integrity of mucosal surface, and uniform enhancement were independent predictive factors of imaging features in the differential diagnosis of gastric schwannoma and gastric stromal tumor(all P<0.05). The results of logistic regression analysis indicated that the history of gastritis ( OR=0.280, 95% confidence interval 0.138 to 0.566), CA19-9 ( OR=0.940, 95% confidence interval 0.890 to 0.993), carcinoembryonic antigen ( OR=0.794, 95% confidence interval 0.661 to 0.952), and MLR ( OR=0.087, 95% confidence interval 0.009 to 0.860) were independent predictive factors of clinical indicators in the differential diagnosis of gastric schwannoma and gastric stromal tumor ( P<0.001, =0.028, 0.013 and 0.037). The AUCs of the nomograph model in the training and validation set were 0.881 and 0.850, respectively, and the AUCs of the clinical control model in the training and validation set were 0.814 and 0.772, respectively, and the differences were statistically significant ( Z=2.57 and 1.96, P=0.005 and 0.030). The average CI of the nomograph model was 0.885. The results of DCA analysis showed that the overall benefit of the nomograph model was higher than that of the clinical control model. Conclusion:The enhanced CT-based nomograph model can effectively distinguish gastric schwannoma from gastric stromal tumor, and can help physicians to make precise clinical decisions.
