ABSTRACT
Objective To observe compatibility rationality and comparative advantage of analgesic effect of Yuanhu Zhitong Dropping Pills (YZDP) compared with its ingredient and Yueyueshu through dysmenorrhea model induced by oxytocin.Methods Using dysmenorrhea model induced by ip injection of oxytocin to observe the effect of YZDP,Corydalis extract and Angelica dahurica extract on the latency and times of writhing response,and ELISA method was used to test the level of factors associated with pain in plasma,including 5-serotonin (5-HT),norepinephrine (NA),β-endorphin (β-EP),prostaglandin F2α (PGF2α） and prostaglandin E2 (PGE2),and level of dopamine (DA) in brain tissue.Q value was calculated by prime probability addition method,and according to whether the Q value was greater than one to determine whether the effects of YZDP was better than that of single component.Results Compared with model group,YZDP,Corydalis extract and Angelica dahurica extract could significantly prolong the latency of writhing response,decrease writhing times (P ＜ 0.05,0.01 and 0.001),and the Q values were greater than one.Compared with Yueyueshu,effect of Yuanhuzhitong dropping pills was significantly increased (P ＜ 0.05 and 0.01).YZDP and Corydalis extract could increase the level of β-EP as well as PGE2,and decrease the level of 5-HT,NA,DA,PGF2α and the ratio of PGF2α to PGE2 obviously in dysmenorrhea model rats (P ＜ 0.05,0.01 and 0.001).A.dahurica extract can significantly reduce 5-HT and DA level (P ＜ 0.05,0.01).Q values of β-EP,NA,DA and PGE2 were greater than one.Compared with Yueyueshu,YZDP increased the levels of β-EP and PGE2,and decreased the levels of 5-HT,PGF2α and PGF2α/PGE2 significantly (P ＜ 0.05 and 0.01).Conclusion YZDP has significant analgesic effect on dysmenorrhea model and has compatibility rationality because of better analgesic effect than ingredient use only.Compared with Yueyueshu,YZDP has the characteristic of working early and better analgesic effect.

ABSTRACT
This study was designed to explore the mechanism of Yuanhu Zhitong Dropping Pills (YHZT) in the treatment of primary dysmenorrhea by pharmacological network technology and establish a research approach of "Compound-Target-Pathway-Disease" network. Twenty-eight compounds absorbed into blood including 22 prototype and 6 metabolites of YHZT were submitted to PharmMapper and Kyoto Encyclopedia of Genes and Genomes (KEGG) bioinformatics softwares to predict the target proteins and related pathways respectively. The network of "Compound-Target-Pathway-Disease" was constructed and analyzed using Cytoscape software. The in silico prediction results showed that the 28 constituents of YHZT affected 111 pathways through 109 target proteins. Among them, a total of 52 proteins and 31 pathways were related to the primary dysmenorrhea. The effect of YHZT on primary dysmenorrhea may be dependent on regulation of the proteins and pathways related with hormonal regulation, central analgesia, spasmolysis, inflammation and immunoregulation.
ABSTRACT
The research of effective components of Chinese materia medica (CMM) is one of the key points of modernization of traditional Chinese medicine (TCM), is the core of interpreting overall efficacy and mechanism of TCM, and is the important foundation of realizing the safety, efficacy, and quality control of CMM. Previous studies mostly focused on the binary research mode of "component-effect". However, in this paper, the triarchic theory of "property-effect-component" was proposed and the research strategy and mode of exploring the mechanism, effective components, and quality markers (Q-Marker) of TCM were established based on the basic properties of TCM, basic concepts and terms of TCM theory and also related with the core contents of TCM theory including syndrome differentiation and treatment, rules of treatment, method of treatment, compatibility regularity, and drug property. The Yuanhu Zhitong Dropping Pills (YZDP) were taken as an example for demonstration research and corydaline, tetrahydropalmatine, protopine, imperatorin, and isoimperatorin were determined to be the Q-Marker of YZDP.
