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.

OTX1 gene is one of the pivotal transcriptional factors involved in the neurogenesis.In order to overexpress the OTX1 gene in distinct cell types and find out its contribution to the proliferation and differentiation of stem cells in vitro,OTX1 cDNA was subcloned into lentiviral vectors.The resulting constructions pDUETOTX1,pDUETGFPOTX1 and pDUETGFP were packaged in 293 cells producing viral particles to transduce 293T cells,SY5Y cells,mouse embryonic stem cells and E15 neural stem cells.It was proved that the transferred OTX1 gene was located in the nuclei of the transduced cells in stead of plasma.Lentivirus is an ideal vector delivering gene to different cells.The overexpression of OTX1 in transduced 293T cells were validated by Western blot and immunofluorescence.

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.

Objective To investigate the relationship between pure -tone audiometry (PTA ) ,speech dis‐crimination abilities in quiet or in noise and the international outcome inventory for hearing aids (IOI-HA) in pres‐bycusis patients .Methods Twenty presbycusis subjects were tested in this study .Pure-tone audiometry (PTA) and speech discrimination threshold were obtained before being fitted with hearing aids .They weared hearig aids more than six months ,and pure-tone audiometry ,speech discrimination scores in quite(the level = 65 dB SPL) and in noise(signal to noise ratio = 10 dB) were carried out in sound field .A stepwise forward multiple-regression analysis was performed to investigate the impact of PTA and speech discrimination scores to IOI-HA .Results The PTAs before or after hearing aid fittings showed a negative association with IOI-HA ,while speech discrimination scores in quiet or in noise before or after hearing aid fittings showed a positive association with IOI-HA .Speech discrimination threshold in noise was identified as a single predictor of IOI-HA(P<0 .001) .Conclusion The relation between speech discrimination scores in noise and IOI-HA suggests that a poor score might limit the hearing aids outcome .The speech discrimination scores in noise help the clinicians predict the outcomes of hearing aid in real‐ities .

Objective To observe the changes in cardiopulmonary exercise test (CPET) variables of children with frequent premature ventricular contraction (PVC)before and after creatine phosphate treatment,to examine the difference of CPET results between PVC patients and healthy children,and to evaluate the effect of frequent PVC on the cardiac reserve function in children.Methods One hundred and nine frequent PVC children and 98 healthy children underwent treadmill exercise test and CPET respectively,the changes of CPET variables were observed among patients before and after treatment as well as among the healthy children.CPET variables include maximal oxygen consumption/kg (VO2max/kg),maximal oxygen consumption/heart rate( VO2max/HR),HR( at different time point),anaerobic threshold ( AT),and AT/VO2 maximum prediction (AT/VO2max pred).Results Before creatine phosphate treatment,VO2max/kg,VO2max/HR and AT/VO2max in frequent PVC children were ( 22.9±7.4 ) ml/( kg·min),( 9.3 ± 1.5 ) ml,( 15.5 ±2.7 ) ml/( kg· min).After creatine phosphate treatment,VO2 max/kg,VO2 max/HR and AT/VO2 max were (26.4 ± 6.0) ml/( kg· min),( 11.4 ± 3.3 ) ml,and ( 17.4 ± 3.8 ) ml/( kg· min).These CPET variables after creatine phosphate treatment in frequent PVC children were obviously higher than those before treatment and there was a significant difference [ VO2 max/kg ( t =2.11,P ＜ 0.001 ),VO2 max/HR ( t =4.02,P ＜ 0.001 ),AT( t =10.2,P ＜ 0.001 )].Control group of 98 healthy children had negative CPET results.Conclusion Cardiac reserve function decreases in frequent PVC children.After treatment,the exercise capacity and cardiac reserve function can be improved.CPET can reflect cardiac functional reserve changes in PVC children.

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.
