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.

It reduced the detection time greatly and has great value in early diagnosis of bacteria in intracranial infection. It should be of great significance for guiding clinical treatment.

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.

An efficient and repeatable approach in transforming the foxtail millet (Setaria italica ) using Agrobacterium LBA4404 horboring the plasmid pBI121 was established. Factors affecting transformation efficiency were investigated including the genotype, explants, the density of bacteria, the duration for inoculation and co-cultivation, and the concentration of acetosyringone in the medium. The maximum transformation conditions were: the callus induced from inflorescence was used as explant; the duration for inoculation with Agrobacterium at low cell density was 30-40 min; for the co-cultivation , the suitable concentration of acetosyringone in the medium was 0.1 mmol/L, and the duration was 2 days.

Objective Tubulointerstitial fibrosis(TIF) is the most important marker reflecting the degree of renal function decline and prognosis and hydrogen sulfide ( H2 S) is crucial in maintaining normal renal function and many diseases of renal injury. The aim of the article was to investigate the effects of exogenous H2 S on the expressions of angiotensinⅡ ( AngⅡ) , proliferating cell nuclear antigen (PCNA) and transforming growth factor beta-1 (TGF-β1) in rats with unilateral ureteral obstruction (UUO). Methods TIF rat model was built with UUO. Ninety-six SD rats were randomly divided into four groups:sham operation group, modelgroup, UUO+low-dose NaHS treatment group ( low dose group) and UUO+high-dose NaHS treatment group ( high dose group) ( n=24, respectively) . Rats in model group were treated with left-side ureteral obstruction and ureteral separation without obstruction was done in sham operation group. UUO rats in two treatment groups were injected intraperitoneally with two different doses of sodium hydrosulfide (NaHS, donor of endogenous H2 S), respectively. HE and Massonstaining and immunohistochemical staining were performed at the 7 d, 14 d and 21 d, respectively. Results In sham operation group, the expressions of AngⅡ, PCNA, and TGF-β1 were found in microamount in tubulointerstitium at each time points. Compared with sham operation group, the expressions of AngⅡ, PCNA and TGF-β1 in model group increased( P<0.01) . While in comparison to model group, the expressions of AngⅡ, PCNA and TGF-β1 decreased in low dose group and high dose group, but no significant differ-ence was found between low dose group and high dose group. Conclusion Exogenous H2 S supplementation can attenuate TIF partly via downregulating the expressions of AngⅡ, PCNA and TGF-β1 .
