The study of quality control of Chinese medicine has always been the hot and the difficulty spot of the development of traditional Chinese medicine (TCM), which is also one of the key problems restricting the modernization and internationalization of Chinese medicine. Multivariate statistical analysis is an analytical method which is suitable for the analysis of characteristics of TCM. It has been used widely in the study of quality control of TCM. Multivariate Statistical analysis was used for multivariate indicators and variables that appeared in the study of quality control and had certain correlation between each other, to find out the hidden law or the relationship between the data can be found,.which could apply to serve the decision-making and realize the effective quality evaluation of TCM. In this paper, the application of multivariate statistical analysis in the quality control of Chinese medicine was summarized, which could provided the basis for its further study.

Objective To assess the estimated 10-year risk of stroke among hypertensive outpatients known with diabetes from cardiovascular clinics of 36 tertiary hospitals in China and to analyze the characteristics of the risk factors and the 10-year risk of stroke between the southern and the northern patients.Methods A multi-center prevalence survey was conducted from October 2011 to June 2012.Hypertensive outpatients known with diabetes were enrolled from cardiovascular clinics of 36 tertiary hospitals in China.A total of 15 914 outpatients were included in the final analysis.The 10-year probability of stroke was evaluated by the Framingham stroke risk profile.According to the 10-year probability of stroke,patients were divided into low risk (≤ 5％),medium risk (6％ ～9％) and high risk (≥10％).Results (1) Of all the hypertensive outpatients known with diabetes,the mean age was (64.6 ± 10.1) years and the mean systolic pressure was (138.7 ± 19.3) mmHg(1 mmHg =0.133 kPa).Among them,7.4％ with atrial fibrillation,11.2％ with left ventricular hypertrophy,57.2％ with cardiovascular diseases,17.1％ smokers and 37.0％ using mono-hypoglycemic agent.The southern patients who were older with more smokers had higher proportions of men and left ventricular hypertrophy,lower Levels of systolic blood pressure,and lower proportions of other cardiovascular diseases than those of the northern patients (all P ＜ 0.05).(2) The mean 10-year probability of stroke was (20.9 ± 16.2) ％.The southern patients had a higher mean 10-year probability of stroke than that of the northern patients [(22.4 ± 17.1)％ vs (19.7 ± 15.2)％] (P ＜ 0.01).After adjusted by age and sex,the southern patients still had a higher mean 10-year probability of stroke (P ＜0.05).(3) All the patients had 7.7％ with low risk,17.4％ with medium risk,and 74.9％ with high risk.The southern patients had lower proportions of low and medium risk than those of the northern patients (6.7％ vs 8.4％,15.5％ vs 18.9％),but had a higher proportion of high risk than that of the northern patients (77.7％ vs 72.7％,all P ＜ 0.01).Conclusions Among the hypertensive outpatients known with diabetes from the cardiovascular clinics of our study,most of them were at the 10-year high risk of stroke.The southern patients had a higher mean 10-year probability of stroke than that of the northern patients.

Objective:To establish a method of evaluating the reproducibility of the preparation process of Xiaozheng-Zhitong cataplasm. Methods:Used fingerprint spectrum technology and in vitro release test to evaluate the reproducibility preparation process of Xiaozheng-Zhitong cataplasm. By using HPLC to establish the fingerprint of Xiaozheng-Zhitong cataplasm. The chromatographic column was an Agilent HC-C18 column (4.6 mm×250 mm, 5 μm); the detection wavelength was 280 nm; the flow rate was 1 ml/min; the column temperature was 25 ℃. The mobile phase was acetonitrile-0.2% phosphoric acid aqueous solution, used gradient elution method. An HPLC method for the determination of tetrahydropalmatine content was established, and the vertical Franz diffusion cell method was used to investigate its in vitro release. Results:The results showed that the similarity between the 10 batches of Xiaozheng-Zhitong cataplasm and the control map was above 0.95, indicating that the process of Xiaozheng-Zhitong cataplasm was stable and feasible; the cumulative release amount of tetrahydropalmatine was 0.23 mg in 24 hours, and the cumulative release rate in 8 hours was 91.54%, and the RSD of 6 samples at each time point was <3%. Conclusion:The method of evaluating the reproducibility of the preparation process of Xiaozheng-Zhitong cataplasm was established by using fingerprint technology and in vitro release; it can provide a reference and scientific basis for the evaluation of the reproducibility of the preparation process of the plaster.

0.05).Conclusions By our detection to healthy full-term neonates of their lipid levels,the recommended borderline up-limits of TC,TG and LDL-C are above 2.71 mmol/L,1.29 mmol/L and 1.12 mmol/L,respectively.The recommended up-limits are above 3.28 mmol/L,1.63 mmol/L and 1.78 mmol/L,respectively.
