This study aimed to explore the mechanism of Xiaoyao San(XYS) in the treatment of three diseases of liver depression and spleen deficiency, ie, depression, breast hyperplasia, and functional dyspepsia, and to provide a theoretical basis for the interpretation of the scientific connotation of "treating different diseases with the same method" of traditional Chinese medicines. Traditional Chinese medicine systems pharmacology database and analysis platform(TCMSP) was used to screen the active components of XYS which underwent principal component analysis(PCA) with the available drugs for these three diseases to determine the corresponding biological activities. The targets of XYS on depression, breast hyperplasia, and functional dyspepsia were obtained from GeneCards, TTD, CTD, and DrugBank databases. Cytoscape was used to plot the "individual herbal medicine-active components-potential targets" network. The resulting key targets were subjected to Kyoto encyclopedia of genes and genomes(KEGG) pathway analysis and gene ontology(GO) enrichment analysis. A total of 121 active components of XYS and 38 common targets in the treatment of depression, breast hyperplasia, and functional dyspepsia were collected. The key biological pathways were identified, including advanced glycation and products(AGEs)-receptor for advanced glycation and products(RAGE) signaling pathway in diabetic complications, HIF-1 signaling pathway, and cancer-related pathways. The key targets of XYS in the treatment of depression, breast hyperplasia, and functional dyspepsia included IL6, IL4, and TNF, and the key components were kaempferol, quercetin, aloe-emodin, etc. As revealed by the molecular docking, a strong affinity was observed between the key components and the key targets, which confirmed the results. The therapeutic efficacy of XYS in the treatment of diseases of liver depression and spleen deficiency was presumedly achieved by reducing the inflammatory reactions. The current findings are expected to provide novel research ideas and approaches to classify the scientific connotation of "treating different diseases with the same method" of Chinese medicines, as well as a theoretical basis for understanding the mechanism of XYS and exploring its clinical applications.

Guilingji (GLJ), a traditional Chinese medicine, is of wide concern because of its remarkable antiaging effect with a long application history. It mainly consists of traditional Chinese herbs, that is, Ginseng radix et rhizoma rubra. This study focused on the anti-aging effects of GLJ on natural aging rats and its underlying mechanisms. Morris water maze was used to determine the learning and memory ability of rats. The levels of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), malondialdehyde (MDA), acetylcholine (ACh), and acetylcholinesterase (AChE) in serum were determined. Furthermore, a 1H-NMR-based serum metabolomics coupled with multivariate data analysis was used to identify potential biomarkers and corresponding metabolic pathways. The results showed that GLJ significantly improved the learning and memorial dysfunctions of natural aging rats. The mechanisms of the anti-aging and memory ameliorative effects of GLJ related to balancing oxidative stress, improving cholinergic system. Its specific mechanism of action may be through regulating pyruvate metabolism and arginine and proline metabolism.

ETHNOPHARMACOLOGICAL RELEVANCE: Guilingji (GLJ), a famous and classical traditional Chinese medicine (TCM) prescription, has been used to extend the lifespan and improve the life qualities of the elderly for hundreds of years in China. AIM OF THE STUDY: We aimed to explore the protective effects of GLJ on the testicular dysfunction of aging rats, as well as the regulating effects of GLJ on the metabolic disturbance and metabolite changes in natural aging rats. MATERIALS AND METHODS: Forty 23-month-old rats were divided randomly into four groups, including the old control group and three groups of GLJ treatment at 37.5, 75, and 150 mg/kg doses, respectively. Additionally, 10 four-month rats were included as the youth control group. Testicular dysfunction was first evaluated by measuring the changes in the wet weights of the testicles, concentration of serum testosterone (T), and morphologic changes of the testis. Subsequently, an 1H NMR-based metabolomics approach coupled with multivariate analysis, including partial least squares discriminant analysis (PLS-DA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) was applied to monitor the metabolite changes. RESULTS: Compared with the old control group, the wet weights of the testicles and T concentration were significantly increased, while the morphologic abnormality of testicular tissues was improved by a 4-week treatment course with GLJ. Furthermore, compared with the old control group, the urinary levels of alanine, pantothenate, phenylalanine, ß-hydroxybutyrate and pyruvate were significantly decreased after a 4-week treatment course with GLJ. Additionally, we found that amino acid metabolism and pyruvate metabolism were significantly involved in the regulatory effect of GLJ. CONCLUSIONS: The current findings provided, for the first time, sound evidence of the protective effects of GLJ on testicular dysfunction from both biochemical and metabolomics perspectives. The mechanisms of GLJ could be related to regulating amino acid metabolism and pyruvate metabolism. The current study lays an important foundation for further research and for the broad clinical application of GLJ.

ETHNOPHARMACOLOGICAL RELEVANCE: The quality control of Traditional Chinese medicine (TCM) is a scientific problem and an industrial issue, which hampers the development of evidence based TCM. The concept of quality markers (Q-markers) is proposed and has been applied to the quality evaluation of TCM based on its clinical efficacy. However, more specific methods are needed to put this idea into practice. The standard decoction is a representative of decoction used in clinical practice and it can be used for the discovery of Q-markers related to the clinical efficacy of TCM. AIM OF THE STUDY: In this study, a systemic strategy was established to discover Q-markers related to the clinical efficacy of TCM Ephedrae Herba (EH), dried stem of Ephedra sinica Stapf. The different processed materials of EH have different clinical applications, though originating from the same medicinal herb. MATERIALS AND METHODS: The standard decoction of each of the processed materials was prepared and a 1HNMR metabolomics approach and total polysaccharide analysis were used to identify potential Q-markers related to the different clinical applications of EH. Correlation analysis was made of the measured biological activity and the holistic chemical profile. RESULTS: The results showed that total polysaccharides and alkaloids were Q-markers for EH preparations. CONCLUSION: This study demonstrates that the standard decoction is a reasonable research objective to explore chemical markers that correlate with the clinical efficacy of TCM.

OBJECTIVE: To observe the effect of Dingguier umbilical paste on rats with functional dyspepsia and mice with splenic asthenia, and investigate the related mechanism. METHOD: Functional dyspepsia models of rats were made by irregular food intake plus diluted hydrochloric acid. Successional treatments were offered for 14 days. The rats weights, contents of serum NO, AChE and MC were measured. The rats with splenic asthenia were made by rhubarb feed, and observed the affection of gastric emptying. RESULT: Compared with those in the model control group, the weight of rats in all dosages Dingguier umbilical paste groups increased obviously (P < 0.05), pepsin activity of rats in the dosage (1.34 g x kg(-1)) Dingguier umbilical paste groups was significantly higher and the contents of NO and quantities of MC in the dosage (2.67 g x kg(-1)) Dingguier umbilical paste groups decreased clearly (P < 0.05), and the contents of serum AChE in all dosages Dingguier umbilical paste groups rose apparently. The weight of mice with splenic asthenia increased obviously, accelerated gastric emptying, and improved the symptom. CONCLUSION: Dingguier umbilical paste has significant improvement of indigestion. The related mechanism may be to reduce the content of serum NO and the quantity of MC and enhance the content of serum AChE.
