This study aims to explore the mechanism of Jiaotai Pills in treating depression based on metabolomics and network pharmacology. The chemical constituents of Jiaotai Pills were identified by UHPLC-Orbitrap Exploris 480, and the targets of Jiaotai Pills and depression were retrieved from online databases. STRING and Cytoscape 3.7.2 were used to construct the protein-protein interaction network of core targets of Jiaotai Pills in treating depression and the "compound-target-pathway" network. DAVID was used for Gene Ontology(GO) function and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analyses of the core targets. The mouse model of depression was established with chronic unpredictable mild stress(CUMS) and treated with different doses of Jiaotai Pills. The behavioral changes and pathological changes in the hippocampus were observed. UHPLC-Orbitrap Exploris 120 was used for metabolic profiling of the serum, from which the differential metabolites and related metabolic pathways were screened. A "metabolite-reaction-enzyme-gene" network was constructed for the integrated analysis of metabolomics and network pharmacology. A total of 34 chemical components of Jiaotai Pills were identified, and 143 core targets of Jiaotai Pills in treating depression were predicted, which were mainly involved in the arginine and proline, sphingolipid, and neurotrophin metabolism signaling pathways. The results of animal experiments showed that Jiaotai Pills alleviated the depression behaviors and pathological changes in the hippocampus of the mouse model of CUMS-induced depression. In addition, Jiaotai Pills reversed the levels of 32 metabolites involved in various pathways such as arginine and proline metabolism, sphingolipid metabolism, and porphyrin metabolism in the serum of model mice. The integrated analysis showed that arginine and proline metabolism, cysteine and methionine metabolism, and porphyrin metabolism might be the key pathways in the treatment of depression with Jiaotai Pills. In conclusion, metabolomics combined with network pharmacology clarifies the antidepressant mechanism of Jiaotai Pills, which may provide a basis for the clinical application of Jiaotai Pills in treating depression.

This study aimed to investigate the effect of Jiaotai Pills on protein expression in the hippocampus of the rat model of chronic unpredictable mild stress(CUMS)-induced depression by quantitative proteomics and explore the anti-depression mechanism of Jiaotai Pills. The SD rats were randomized into control, model, Jiaotai Pills, and fluoxetine groups(n=8). Other groups except the control group were subjected to CUMS modeling for 4 weeks. After 4 weeks of continuous administration, the changes of behavior and pathological morphology of the hippocampal tissue were observed. Proteins were extracted from the hippocampal tissue, and bioinformatics analysis was performed for the differentially expressed proteins(DEPs) identified by quantitative proteomics. Western blot was employed to verify the key DEPs. The results showed that Jiaotai Pills significantly alleviated the depression behaviors and hippocampal histopathological changes in the rat model of CUMS-induced depression. A total of 5 412 proteins were identified in the hippocampus of rats, including 65 DEPs between the control group and the model group and 35 DEPs between the Jiaotai Pills group and the model group. There were 16 DEPs with the same trend in the Jiaotai Pills group and the control group, which were mainly involved in sphingolipid, AMPK, and dopaminergic synapse signaling pathways. The Western blot results of Ppp2r2b, Cers1, and Ndufv3 in the hippocampus were consistent with the results of proteomics. In conclusion, Jiaotai Pills may play an anti-depression role by modulating the levels of Ppp2r2b, Cers1, Ndufv3 and other proteins and regulating sphingolipid, AMPK, and dopaminergic synapse signaling pathways.

AIM:To investigate the change of late sodium current (INaL) and the effect of Ca2+/calmodulin-dependent protein kinaseⅡ (CaMKⅡ) inhibitor KN-93 on INaLin the cardiomyocytes after isoproterenol-induced heart fai-lure (HF) in rabbits. METHODS:The rabbit model of HF was induced by injecting isoproterenol (300 μg·kg-1· d-1) for 15 d. One month later, all rabbits received by echocardiography and HE staining to observe the morphological changes of myocardium for evaluating the HF model. The protein expression of NaV1.5, CaMKⅡδ and phosphorylated CaMKⅡδ was determined by Western blot. The ventricular myocytes were isolated from the rabbits of normal saline(NS) group and HF group by Langendorff perfusion, and the whole-cell patch-clamp technique was used to record INaL. RE-SULTS:Compared with NS group,the heart rate in HF group was increased (P<0.01), the ventricular cavity was en-larged (P<0.05),and the cardiac function was decreased(P<0.01). Compared with NS group,the cardiomyocytes in HF group arranged in disorder, vacuolar degeneration and myocardial interstitial edema were observed, and fibrous tissue increased. The protein levels of NaV1.5,CaMKⅡδ and phosphorylated CaMKⅡδ in HF group were higher than those in NS group(P<0.01). INaLin HF group significantly increased compared with NS group (P<0.01). After adding sea anemone toxin Ⅱ (ATXⅡ), the density of INaLin HF group and NS group was significantly increased, but that in HF group increased more obviously than that in NS group (P<0.01). After ATXⅡ had induced stable current, we added KN-93 into NS group and HF group,and we found that the ATXⅡ-increased INaLin NS group and HF group was signifi-cantly decreased(P<0.05).CONCLUSION:CaMKⅡinhibitor KN-93 inhibits the increase in INaLin HF rabbits,which may be related to the activity of CaMKⅡδ and the regulation of CaMKⅡ δ on INaL.
