Objective To optimize the extracting condition of total isoflavones from Fructus Sophorae by subcritical water extraction.Methods Taking isoflavones yield as index and genistin as control,the technology parameter of subcritical water extraction of Fructus Sophorae isoflavones was optimized by single factor and orthogonal experiment.Results The yield of Fructus Sophorae total isoflavones in the extracts was 23.3% at 130 ℃ for 45 min with the liquid-solid ratio of 12.5 mL/g.Conclusion Compared with traditional extracting methods,subcritical water extraction is a new developing technology in recent years.Its advantage is fast,good-selective.

So far, an evaluation system for the patent value of traditional medicine is in absence. For this reason, an evaluation system had been established in this paper, by taking advantage of unique attributes of traditional medicine. This system consisted of 10 key indexes equipped with the algorithm for the calculation of original value and comparative value. The comparative value of patent was easier to show the value difference among patents. In consideration of strong correlation between the legal value, technical value, and economic value of the patent and be-tween evaluation indexes thereof, three kinds of value were combined together without discrimination for integral e-valuation. Besides, with inclusion of specific indexes in this field, the non-specific indexes related or indexes un-available were excluded. Because there is no personal rating involved, this evaluation system is appropriate for the automatic evaluation of patents of traditional medicine and other fields .

Objective To observe the effects of modifiedDanshen Decoction on spermidine/spermine acetyltransferase (SSAT) /polyamine pathways of SD rats with IRI; To investigate its protective mechanism. Methods The model of IRI was established by ligating left anterior descending coronary artery for 30 min followed by reperfusion for 90 min. The SD rats were randomly divided into the control group, sham-operation group, model group and modifiedDanshen Decoction group, with 10 rats in each group. The myocardial infarction size was measured by using TTC staining. The contents of SSAT were measured by ELISA. The SSAT mRNA and SSAT protein expression level were detected with real-time fluorescent quantitative PCR method and Western blot, respectively. The contents of polyamines (putrescine, spermidine, spermine) in cardiac tissue were detected by HPLC. Results Compared with sham-operation group, the myocardial infarction size, the SSAT content, the SSAT mRNA and SSAT protein expression levels of model group increased significantly, the contents of polyamines decreased significantly, with statistical significance (P<0.01); Compared with model group, the myocardial infarction size of modifiedDanshen Decoction group was significantly reduced, while the SSAT content and SSAT mRNA and protein expression level decreased significantly, the contents of polyamines increased, with statistical significance (P<0.05, P<0.01).ConclusionModifiedDanshen Decoction can adjust the SSAT polyamine pathways and increase polyamine content in cardiomyocytes, and thus play a role of protection of myocardial ischemia-reperfusion injury.

ObjectiveTo construct and evaluate the transformation model of the Constitution in Chinese Medicine Questionnaire (CCMQ) to SF-6Dv1 health utility and broaden the applications of CCMQ. MethodsThe data of CCMQ and SF-6Dv1 were collected from 595 participants at baseline, 3 months and 6 months after the comprehensive intervention suitable for the corresponding traditional Chinese medicine (TCM) constitution. The estimation and validation datasets were constructed, and four statistical algorithms including the ordinary least squares (OLS), MM robust regression (MM), censored least absolute deviations (CLAD) and the Tobit model were used to create alternative models. The mean absolute error (MAE), root mean square error (RMSE) and intraclass correlation coefficient (ICC) were used to evaluate the prediction performance of the model. ResultsThe constitution scores of all TCM constitutions by CCMQ was significantly correlated with the SF-6Dv1 health utility value measured at three timepoints; the health utility value of the SF-6Dv1 was positively correlated with gentleness type (r=0.596, r=0.578, r=0.606, all P<0.05) and negatively correlated with eight unbalanced constitutions (r=

ObjectiveTo present the health status of traditional Chinese medicine (TCM) constitutions more intuitively and comprehensively based on improved radar chart. MethodsParticipants who completed a 26-week comprehensive intervention based on TCM constitution from February 2013 to January 2014 in Zhuhai branch of Guangdong Provincial Hospital of Chinese Medicine were included in the study. They were divided into groups according to gender and age, i.e. young, middle-aged, and elderly male and female groups. TCM constitution scale and health survey short form (SF-36) were used to evaluate the 9 basic TCM constitution types and quality of life at three time points, including pre-intervention (T1), at 13-week intervention (T2), and at 26-week intervention (T3). The improved radar charts were drawn to visually present the comprehensive evaluation results on the health status of 9 TCM constitutions, and graphic features (area S value, perimeter L value) were extracted to construct a comprehensive health index for TCM constitutions (H value). Spearman correlation analysis was used to analyze the correlation between H value and SF-36 total score. ResultsAmong the included 509 participants, there were 45 elderly male, 76 elderly female, 60 middle-aged male, 140 middle-aged female, 53 young male and 135 young female. The radar charts for comprehensive evaluation of TCM constitution health status showed that the total areas for all groups increased at T3 compared to T1, with the most significant increase in the young population. In the middle-aged population, the fan-shaped areas of certain constitutions decreased at T2 than T1. At T3, the radar chart shapes for females were more balanced than males in the same age group. By calculating the features of function graphs, it was found that the S, L, and H values for the elderly population were relatively higher than those for the middle-aged and young population with the same gender, and the young population increased by highest ratio. The values measured at T3 compared to T1 showed average increase of 26% for S value (11% for the middle-aged and 14% for the elderly), 22% for L value (10% for the middle-aged and the elderly each), and 22% for H value (10% for the middle-aged and 9% for the elderly). The female had lower S and L values, as well as higher H value than the male of the same age group measured at T3. The correlation coefficient between the H value of all participants and the total SF-36 score was 0.662 (P<0.01). ConclusionThe comprehensive evaluation model for the health status of TCM constitution based on the improved radar chart constructed in this study can present the health status of TCM constitutions and intervention effectiveness more comprehensively and intuitively. It is suggested to regulate the constitution in pursuit of the dynamic balance of the constitution health status, as well as consider the parts from the whole, and put focus on the balance of nine TCM constitutions.
