Objective: The primary aim of this research is to systematically sort out and analyze available documents for yang deficiency syndrome in traditional Chinese medicine, providing innovative ideas and methods for statistical study of yang deficiency syndrome. Methods: Based on the China National Knowledge Internet (CNKI) and Chongqing VIP databases, using "yang deficiency", "deficiency cold", and "patient" as keywords, we searched literature of clinical researches and used "ratio-comparison" and "integration-comparison" to analyze objective data after data preprocessing. Relative importance value of physiological and biochemical parameters were reflected by P value calculated by ratio-comparison or Q value by integration-comparison. Results: With calculation of relative importance values of clinical indicators among various systems, we got the ranking of relative importance of different indexes. Triiodothyronine and urine 17-hydorxycorticosteroid of endocrine system, immunoglobulin A of immune system, and the ratio of cyclic adenosine monophosphate to cyclic guanosine monophosphate, which had great |P| (or |Q|) values and negative P (or Q) values, had a clearly lower level in yang deficiency patients than in the control; hemorheological indicators such as plasma viscosity, whole blood reduced viscosity and erythrocyte electrophoresis time had small |P| (or |Q|) values. These indicators, however, showed less importance for reflecting yang deficiency. Conclusion: Ratio-comparison method and integration-comparison method employed in this study have merits of efficiency and robustness. After detailed compiling and mining of all available data, we have made reasonable advice on the most relevant index of yang deficiency for further study of the essence of this syndrome.

The theory of four properties (Qi) and five tastes (Wei) is the core of the property theory of Chinese materia medica. It is known that Qi and Wei are associated with the pharmacological effects (Xiao) of herbs. This study took records of all 365 Chinese herbs in Shennong's Classic of Materia Medica (Shennong Ben Cao Jing) as the data resource and established a three-dimensional data cube, in the purpose of finding out and analyzing the frequent patterns and valued association rules of Qi, Wei and Xiao based on Apriori algorithm. The results of this study may give rise to innovative ideas and methods in research of traditional Chinese materia medica.

Studying the essence of syndromes (Zheng) in traditional Chinese medicine (TCM) is a fundamental challenge in basic theoretical research of TCM. The relationship between any given syndrome and biochemical indicators is one of the important aspects of the study. As the indexes selected in each study are specific to a particular Western medical disease diagnosis, and the disease factor is inevitably introduced into the study, the effect of disease factor on the index changes cannot be assessed effectively by traditional data processing methods. This is known as "the same syndrome with different reasons", which has resulted in confusion in TCM research. This study aimed at providing a mathematical tool to address this issue. Based on information theory and the residual-split method, the syndrome information, which was covered in the index variation, was quantitatively calculated in this paper as an independent part of the disease factor. A mathematical model capable of objectively assessing and statistically testing the effect of the syndrome factor on the index changes was established. Applying this model to literature data of studies on the relationship between cyclic nucleotides and yang-deficiency syndrome showed following results. First, the values of yang-deficiency syndrome information were negative for cyclic adenosine monophosphate (cAMP) while positive for cyclic guanosine monophosphate (cGMP) in all included literature. This indicated that the group of yang-deficiency syndrome was correlated with an obvious trend of reduced cAMP levels and increased cGMP levels. Second, the statistical test results of yang-deficiency syndrome information of the two indexes were different among the literature included. The quality of original data was considered as a possible reason. Third, the significant differences between the yang-deficiency group of a specific disease and the normal group may, in some cases, be caused by a disease factor rather than a syndrome factor. The mathematical model provided a reasonable mathematical tool for the analysis of disease factor and syndrome factor in clinical research of TCM, suggesting that the mathematical model may give rise to innovative ideas and methods in the study of syndromes.

Background Fractalkine is involved in the impairment of endothelium by mediating inflammatory cell chemotaxis.Aspirin inhibites many kinds of cytokine expression.Objective To investigate the effect of aspirin on tumor necrosis factor ?(TNF-?) stimulated fractalkine expression in human umbilical vein endothelial cells (HUVEC) and its mechanism.Methods HUVEC were grouped as follows:control group;TNF-?-stimu- lated;TNF-?+NS-398;TNF-?+PDTC and TNF plus various concentration of aspirin (0.02,0.2,1.5 mmol/L). The level of mRNA and protein expression of fractalkine and nuclear factor(NF)-kB p65 was determined by RT- PCR and Western blot.Results 1)Fractalkine mRNA and protein level was increased after 4 ?g/L TNF-? stim- ulation in HUVEC(both P

Hydrocortisone-induced yang-deficiency animal model has now become the generally accepted model of yang deficiency. However, assessing the most appropriate dose of hydrocortisone is a long-term challenge. For analyzing the modeling dose, the authors have built several kinds of yang-deficiency models induced by hydrocortisone at different doses, and analyzed the experimental data with various mathematical statistical methods. In order to discuss the effects of the modeling dose on the basis of previous research, the authors introduced Ridit analysis.

The concepts of cold and hot herbal properties in traditional Chinese medicine (TCM), reflecting the efficacy trends of medicinal herbs, have the Fuzzy characteristics. It is suited for the application of Fuzzy mathematics in research of herbal properties. For a comprehensive evaluation of herbal properties, this work constructed and made a practice of the Fuzzy discrimination model regarding the biological performance of Chinese materia medica.

To compare the effects of Oleum Cinnamomi and water extract of Cortex Cinnamomi in rats with yang-deficiency cold syndrome based on mathematical analysis.

The properties of Chinese materia medica are believed to be the summarization of the effects of biological performance on the various body states. Systemic discussion of chemical-factor elements, body-condition elements, biological-performance elements and their interrelationships is needed for research into the properties of Chinese materia medica. Following the practical characteristics of Chinese medicine, the three-element mathematical model was formed by introducing some mathematical concepts and methods and was used to study the cold or hot property of Chinese medicine, and to investigate the difference in biological performances of the two properties.

OBJECTIVE To present the modified intranasal endoscopic dacryocystorhinostomy (MIEDCR) and the clinical results. To discuss the modified operative technique and its purpose. METHODS A total of 31 cases (35 eyes) with chronic dacryocystitis who underwent MIEDCR were included in this study. There were 27 female and 4 male. The age was ranged from 9 to 70 years (mean 31 years). The preoperative dacryocystography was taken in all cases. The follow up time was 6 to 20 months. RESULTS Among the 31 cases with chronic dacyocystitis, 4 patients suffered bilateral chronic dacyocystitis. Dacryocystitis related to nasal endoscopic surgery was found in 2 cases (2 eyes). Four cases (5 eyes) had prior laser lacrimal duct surgery. Two patients had external dacrypcystorhinotomy experience. 34 MIEDCR procedures (97.1 %) were successful. Twenty eight patients (32 eyes) were free of their symptoms and kept stoma patency. The shift of mucosal flap was found in one case when Merocel was removed. The rhinostomy of another 2 cases were closed due to mucosal scar and one of them received revision surgery. There were no operative complications. CONCLUSION The preserved nasal mucosal flap which was replaced over the denuded bone would avoid scar formation and hyperostosis and is benefit to gain a satisfied and good clinical effects of dacryocystorhinostomy.
