To study the characteristics of pharmacological effects of property combinations of traditional Chinese medicines (TCMs) distributing in the stomach meridian based on medicinal property combination, in order to further define the association relationship between properties of TCMs and their pharmacological effects, and build a bridge for the interpenetration and combination between the medicinal property theory of TCMs and their pharmacological effects. On the basis of the studies on the medicinal property theory of TCMs distributing along the kidney meridian and their pharmacological effects, efforts were made to collect relevant data for medicinal properties and pharmacological effects and mine the characteristics of pharmacological effects that were corresponding to relevant medicinal property combination by processing materials related to medicinal properties and pharmacological effects with the association rules method. According to the analysis, TCMs distributing along the kidney meridian with different medicinal property combinations were significantly differentiated in the pharmacological effects, but shared identical pharmacological effects, such as immunological enhancement. In this study, TCMs distributing along the kidney meridian with different medicinal property combinations were taken as the carriers to closely integrate the traditional Chinese medicine theory with the modem study achievements, lay a solid foundation for further developing and enriching the traditional Chinese medical property theory, while providing a new perspective on the development of modem medicine.

The five-flavor theory of traditional Chinese medicines (TCM) and the flavor efficacy generation mechanism has long been focuses and difficulties in studies on traditional Chinese medicinal properties. In this paper, by using the pharmacophore-based virtual screening technique, the authors discussed the relations between the pungent property and transient receptor potential vanilloid 1 (TRPV1) by studying the TCM components' role in regulating TRPV1 ion channel. The results showed that the matching relationship between TRPV1 agonist pharmacophore model and TCM chemical components could identify the active ingredients from pungent herbs. Therefore, the authors proposed that TRPV1 is one of the potential targets for efficient pungent herbs. The pungent property of TCMs is decided by its chemical components, and consistent with the inherited and additive characteristics.

OBJECTIVETo observe the relation between Pi deficiency syndrome (PDS) and the configuration and functions of extensor digitorum longus (EDL)and soleus (SOL).
METHODSTotally 36 ICR mice were randomly divided into 3 groups according to weight matching principle, the control group, the exhausted group, and the rhubarb group, 12 in each group. Two PDS models were established by either purgation with rhubarb diarrhea (as Group A) or exhausted swimming plus sleep deprivation (as Group B).The cross sectional area (CSA) of type I and II fibers of extensor digitorum longus (EDL) and soleus (SOL), relative proportions of type I and II fibers were measured by m-ATPase histochemical method. The isotonic contraction and the maximum tetanus contraction of EDL and SOL were detected by PowerLab system.
RESULTSCompared with the control group, the body weight, body temperature, and the general health condition of PDS model rats obviously decreased; the spleen index and the thymus index were also lower; the maximal isotonic contraction and the maximum tetanus contraction obviously decreased; the cross section areas of EDL and SOL were reduced with loosely arranged cells. In EDL, the proportion of type I fibers was added and the proportion of type II fibers was lowered. In SOL, there was no change in the proportion of type I and type II fibers.
CONCLUSIONSEDL and SOL were obviously atrophied in the two PDS model mice. The type I fibers of SOL was more significantly atrophied in Group B.

In this study, microcalorimetry was adopted to establish a novel method for detecting the hemagglutination process of Radix Isatidis (Banlangen in Chinese, BLG), and to evaluate the hemagglutination activity diversity of BLG from various habitats. The hemagglutination biothermokinetics curves of positive reagent (phytohemagglutinin, PHA) and 8 batches BLG from different regions of the hemagglutination with 20% rabbit erythrocyte were recorded by microcalorimetry, then biothermokinetics parameters were abstracted, the hemagglutination utility of samples were calculated and analyzed by principal component analysis (PCA) and cluster analysis (CA), meanwhile the results were authenticated by micro-plate agglutination. It showed that the hemagglutination was an exothermic reaction, the reaction rate constant (k: 0.039-73.6 min(-1)), maximum reaction power (Pmax: -1 140.2 - 988.2 microW) and reaction enthalpy (Hi: -529.9 - 717.9 microJ) had good linear correlation with BLG extraction concentration (0.2-1.0 g mL(-1), r > 0.97), and PCA showed Pmax (531-1 335 microW) and Ht (585.2-989.2 microJ) could represent the hemagglutination activity diversity of BLG samples, just confirming with the results of micro-plate agglutination (the agglutination dilution was 3-11 respectively). According to the hemagglutination utility, the BLG samples from Good Agriculture Practice (GAP) regions, main producing area and general regions could be clustered correctly; meanwhile, the biothermokinetics curves with perfect distinctive fingerprint and specificity could give out more information for the quality control and evaluation for BLG. In conclusion, the microcalorimetry method established for detecting the hemagglutination activity of BLG samples on rabbit erythrocyte is sensitive and reliable, and could be adopted as an effective technique in detection aggulatination precisely, quantitatively and consecutively; and provide a novel approach for examining and evaluating quality for Chinese herbal medicine with aggulatinative activity such as BLG.
