Chinese Medicine(CM)has been widely used as an important avenue for disease prevention and treatment in China especially in the form of CM prescriptions combining sets of herbs to address patients’symptoms and syndromes.However,the selection and compatibility of herbs are complex and abstract due to intrinsic relationships between herbal properties and their overall functions.Network analysis is applied to demonstrate the complex relationships between individual herbal efficacy and the overall function of CM prescriptions.To illustrate their connections and correlations,prescription function(PF),prescription herb(PH),and herbal efficacy(HE)intranetworks are proposed based on CM theory to identify relationships between herbs and prescriptions.These three networks are then connected by PF-PH and PH-HE interlayer networks adopting herb dosage to form a multidimensional heterogeneous network,a Prescription-Herb-Function Network(PHFN).The network is applied to 112 classic prescriptions from Treatise on Exogenous Febrile and Miscellaneous Diseases to illustrate the application of PHFN.The PHFN is constructed including 146 functions in PF intra network,89 herbs in the PH intra network,and 163 herbal efficacies in the HE intra network.The results show that herb pairs with synergistic actions have stronger relevance,such as licorice-cassia twig,licorice-Chinese date,fresh ginger-Chinese date,etc.The integration of dosage to the network helps to indicate the main herbs for cluster analysis and automatic formulation.PHFN also reveals the internal relationships between the functions of prescriptions and composed herbal efficacies. 展开更多

Objective To explore the medication rules of traditional Chinese medicine(TCM)and mechanism of action of hub herb pairs for treating insomnia.Methods Totally 104 prescriptions were statistically analyzed.The association rule algorithm was applied to mine the hub herb pairs.Network pharmacology was utilized to analyze the mechanism of the hub herb pairs,while molecular docking was applied to simulate the interaction between receptors and herb molecules,thereby predicting their binding affinities.Results The most frequently used herbs in TCM prescriptions for treating insomnia included Semen Ziziphi Spinosae,Radix Glycyrrhizae,Radix et Rhizoma Ginseng,and Poria cum Radix Pini.Among them,the most commonly used were the supplementing herbs,followed by heat-clearing,mind-calming,and exterior-releasing ones,with their properties of warm and cold,flavors of sweet,Pungent,and bitter,and meridian tropisms of liver,lungs,spleen,kidneys,heart,and stomach.The hub herb pairs based on the association rules included Radix Astragali-Radix et Rhizoma Ginseng,Rhizoma Chuanxiong-Radix Glycyrrhizae,Seman Platycladi-Semen Ziziphi Spinosae,Pericarpium Citri Reticulatae-Radix Glycyrrhizae,Radix Polygalae-Semen Ziziphi Spinosae,and Radix Astragali-Semen Ziziphi Spinosae.Network pharmacology revealed that the cAMP signaling pathway might play a key role in treating insomnia synergistically with HIF-1 signaling pathway,prolactin signaling pathway,chemical carcinogenesis receptor activation,and PI3K-Akt signaling pathway.Molecular docking indicated that there was good binding between the active ingredients of the hub herb pairs and the hub targets.Conclusions This study identified six hub herb pairs for treating insomnia in TCM.These hub herb pairs may synergistically treat insomnia with HIF-1 signaling pathway,prolactin signaling pathway,chemical carcinogenesis receptor activation,and PI3K-Akt signaling pathway through the cAMP signaling pathway. 展开更多

Growth and competition of 14 herb species were investigated in the experimental microcoenosiums in laboratory under the following environmental factors and treatment levels: high and low fertility, clipping and un-clipping, and with and without microbial infusion. The most intense competition and the biggest difference in biomass among the species were detected in the high fertility microcoenosiums subjected to no clipping disturbance. Clippings or low fertility reduced the growth of the competitors and resulted in more even biomass distribution among the species. Successive clippings reduced the total accumulative biomass of the microcoenosiums. Microbial infusion significantly increased the growth of legume species Lotus corniculatus L. and Trifolium pratense L. The growth of Alopecurus pratensis L. was also raised by microbial infusion, whereas Dactylis glomerata L. had more biomass in without-microbial-infusion microcoenosiums than in microbial infusion ones. Most of the 14 species were not obviously affected. The positive effect of microbial infusion was more marked in the low fertility microcoenosiums. 展开更多

[ Objective] The paper presents the effects of Chinese herbal extract on the performance of local chickens for its application in animal production. [Method] The herbal extract Ⅰ and Ⅱ were added to the basal diet of 10 day-old chickens at the ratio of 0.6%, respectively. Then the chickens was fasted and respectively weighed at 0, 17, 24 and 31 days old. And the feed consumption and mortality of each group were recorded to determine average weight, average daily gain, and feed conversion ratio. Economic benefit was also analyzed. [ Result] There was no significant difference in average daily gain between the test groups and the control group as well as between the two test groups (P〉0.05) ; there was signifi- cant difference in feed conversion ratio between the test groups and the control group ( P 〈0.05), but no significant difference between the two test groups ( P 〉 0.05) ; the survival rate and the economic benefits of the test groups were significantly higher than that of control ( P 〈 0.05).

[ Objective] To evaluate the efficacy of integrated Chinese herbs and western medicine on the treatment of swine toxoplasmosis, in order to increase cure rate and lower recurrence rate. [ Method] Pigs artificially infected by Toxoplasma gondii were treated with compound suffonamide and a self-designed Chinese herbs formula, and the quantities of toxoplasma in ascites were determined. Animal regression experiment was per- formed after mice were inoculated with pathological samples of the pigs infected with toxoplasma. After treatment with integrated Chinese herbs and western medicine, the clinical manifestations of pigs were observed and the level of circulating antigen (CAg) in sera was detected. Curative effect indexes of integrated Chinese herbs and western medicine-treated group were compared with that of Chinese herbs-treated group, western medi- cine-treated group and positive control group. [ Result] All the toxoplasma trophozoites were killed by integrated and westem medicine. Regression expedment results showed that toxoplasma appeared only in one mouse that was inoculated with brain of pig. The treated pigs had nonsignificant clinical symptoms; the peak of serum CAg was lower than that of the positive control group and CAg turned negative faster than that of Chinese herbs-treated group, westem medicine-treated group, and positive control group.
