Objective To study the importance of back pain-lassitude as the key symptom in the differentiation of kidney-deficiency syndrome in diabetes patients.Methods Totally 460 diabetics were divided into the pain group(154 cases)and non-pain group(306 cases).The 39 symptoms,signs and behavior were abstracted and each patient was scored according to the details of kidney deficiency scale to analyze the constitution and distribution of kidney-deficiency syndrome.Results There was a significant difference in the total symptom score of the two groups(P

Forsythia suspensa is a herbal medicine that widely used for heat-clearing and detoxification in clinical practice. However, the molecular mechanism of its heat-clearing and detoxifying effect is still unclear. Based on the theory and methods of network pharmacology, the efficacy of the heat-clearing and detoxification of Forsythia suspensa was analyzed in this study. A total of 114 of compounds in Forsythia suspensa were collected, and 15 of effective compounds were obtained by analyzing the bioavailability (OB) and drug-like properties (DL). Then 26 corresponding targets were obtained using reverse pharmacophore-docking method. Using the BioGPS database, the organ location of the target initially was revealed. The compound-targetdisease network model of Forsythia suspensa was constructed by using the Cytoscape, which showed that the material basis of the heat-clearing and detoxification of Forsythia suspensa was to synthesize and synergize the effects by combining various active ingredients of multiple targets, simultaneously. This study explains the scientific mechanism of the heat-clearing and detoxification of Forsythia suspensa, and provides a theoretical foundation for clinical rational usage of Forsythia suspensa.
