Chinese herbal property theory (CHPT) is the fundamental characteristic of Chinese materia medica different from modern medicines. It reflects the herbal properties associated with efficacy and formed the early framework of four properties and five flavors in Shennong's Classic of Materia Medica. After the supplement and improvement of CHPT in the past thousands of years, it has developed a theory system including four properties, five flavors, meridian entry, direction of medicinal actions (ascending, descending, floating and sinking) and toxicity. However, because of the influence of philosophy about yin-yang theory and five-phase theory and the difference of cognitive approach and historical background at different times, CHPT became complex. One of the complexity features was the multiple methods for determining herbal property, which might include the inference from herbal efficacy, the thought of Chinese Taoist School and witchcraft, the classification thinking according to manifestations, etc. Another complexity feature was the multiselection associations between herbal property and efficacy, which indicated that the same property could be inferred from different kinds of efficacy. This paper analyzed these complexity features and provided the importance of cognitive approaches and efficacy attributes corresponding to certain herbal property in the study of CHPT.

Chinese herbal property is the highly summarized concept of herbal nature and pharmaceutical effect, which reflect the characteristics of herbal actions on human body. These herbal actions, also interpreted as presenting the information about pharmaceutical effect contained in herbal property on the biological carrier, are defined as herbal property expressions. However, the biological expression of herbal property is believed to possess complex features for the involved complexity of Chinese medicine and organism. Firstly, there are multiple factors which could influence the expression results of herbal property such as the growth environment, harvest season and preparing methods of medicinal herbs, and physique and syndrome of body. Secondly, there are multiple biological approaches and biochemical indicators for the expression of the same property. This paper elaborated these complexities for further understanding of herbal property. The individuality of herbs and expression factors should be well analyzed in the related studies.

Herbal property theory of traditional Chinese medicines is the theoretical guidance on authentication of medicinal plants, herborization, preparation of herbal medicines for decoction and clinical application, with important theoretical value and prac- tical significance. Our research team proposed the "three-element" theory for herbal properties for the first time, conducted a study by using combined methods of philology, chemistry, pharmacology and mathematics, and then drew the research conclusion that herbal properties are defined as the chemical compositions-based comprehensive expression with complex and multi-level (positive/negative) biological effects in specific organism state. In this paper, researchers made a systematic mathematical analysis in four aspects--the correlation between herbal properties and chemical component factors, the correlation between herbal properties and organism state fac- tor, the correlation between herbal properties and biological effect factor and the integration study of the three elements, proposed future outlook, and provided reference to mathematical studies and mathematical analysis of herbal properties.

Objective: To assay minimal biofilm eradication concentration (MBEC) of various extraction compounds from Galla Chinensis to 5 oral bacterial biofilms, and then to set up traditional Chinese medicine empirical study methods of pharmacodynamic susceptibility. Methods:5 cariogenic bacteria strains were selected (Streptococcus mutans ATCC25175, Streptococcus sanguis ATCC10556, Lactobacillus rhamnosus AC413, Actinomyces naeslundii WVU627, Actinomyces viscosus ATCC19246) in present study. Various extraction compounds of Galla Chinensis were GCE (aqueous extract), GCE-B(300 ml/L alcohol extract), GCE-C(500 ml/L acetone extract),GCE-D(1 000 ml/L acetone extract), gallic acid and methyl gallate. ①Observed oral bacterial biofilm formation in MBECTM-Device at different-time-stages. ②MBECTM -HTP-Assay:The minimal inhibitory concentration (MIC) and minimal biofilm eradication concentration (MBEC) of various extraction compounds of Galla Chinensis on 5 oral bacteria strains were determined. Results:5 oral bacterial biofilm were readily formed on the lid of MBECTM-Device under selected condition (observed by SEM). 5 oral cariogenic bacteria growing as planktonic populations were sensitive to 6 extraction compounds of Galla Chinensis. When compared to 6 extraction compounds of Galla Chinensis, 5 oral cariogenic bacterial biofilm were 2-16 times less susceptible than growing planktonic bacteria. GCE and GCE-B are the most effective medicine against 5 oral cariogenic bacterial biofilm. GCE-C and GCE-D were effective in killing oral-bacterial biofilm at relatively high concentration, but gallic acid and methyl gallate were less effective.Conclusion:GCE and GCE-B are the most effective medicine against 5 oral cariogenic bacterial biofilm of 6 extraction compounds from Galla Chinensis. MBEC can provide a relatively accurate medicine concentration for clinical test.

Eight mongrel dogs were involved in the investigation of sevoflurane effects on renal blood flow (RBF). After intravenous anesthesia and surgical preparation, RBF, MAP, HR, CVP, CO and SV were recorded as baseline. Sevoflurane was then administered to achieve end-tidal concentrations of 1, 2, 3 and 4% in succession. Following 20 mins equilibration at each concentration, and 30 mins after the termination of inhalation, the above parameters were measured repeatly for comparing. Results showed significant dose-related depressions of RBF, MAP, HR and CO with sevoflurane. RBF didn't reduce significantly until MAP decreased to 9.3kPa, with end-tidal concentration of sevoflurane no less than 3%, it didn't recover in step with improved hemodynamic parameters after sevoflurane withdrawal. This study indicates that sevoflurane may influence little on autoregulation of RBF, its dose-related cardiac depression may be responsible for the reduction of RBF.

Objective To study the effect of the combination of rivaroxaban and Xuesaitong injection on deep venous thrombosis (DVT) of lower extremity after spinal surgery.Methods The clinical data of 90 patients undergoing spinal surgery from May 2013 to May 2015 were retrospective analyzed.The patients were divided into two groups randomly: the treatment group and control group.Forty-five patients in treatment group were treated with rivaroxaban and Xueshuantong injection from 1 st day after surgery to one week after off-bed activity, and forty-five patients in control group were treated with rivaroxaban alone.The vessels of lower extremity were detected by doppler ultrasonography pre-surgery, 7-10d and 3 months post-surgery, then the rates of DVT and pulmonary embolism were statistically analysed.Results The DVT rate in treatment group was 8.89%(4 cases), which was significantly lower than 24.4% (11 cases) in control group (P<0.05).Conclusion The anticogulant effect of the combination of rivaroxaban and Xuesaitong injection is stronger than rivaroxaban alone.
