AIM: To establish the method of fingerprinting analysis on Zedoary turmeric oil by GC.Zedoary turmeric oil for the quality control of reference. METHODS: GC method was used to determine the fingerprint and its similarity of Zedoary turmeric oil calculated on Excel and cluster analysis. RESULTS: Seventeen samples of Zedoary turmeric oil indicated that there was a little similarity among them.Based on the cluster analysis,all the Zedoary turmeric oils could be divided into two categories,self-made and market purchasing oil,the latter oils purchased from Liaoning province and Jiangsu province varied considerably.Every category had a common fingerprint mode with clear resemblance. CONCLUSION: When finding the difference between the self-made and the market purchasing Zedoary turmeric oil,quality control requires serious consideration.

Statistical analysis includes statistical description and inference. The former one describes central and dispersion tendency,sampling error and characteristics of data distribution.The key of statistical description is how to properly select the relevant statistic which primarily depends on three elements:characteristics of sample,type of data and its characteristics of distribution.Secondly,we should pay attention to correct matching and combination use of statistics. Statistical inference includes parameter estimation and hypothesis testing. We usually use interval estimation to do parameter estimation.The correct selection of the methods of hypothesis testing needs the following six factors,research purpose,number of research factors,number of groups or research level,types of experiment design,data types and distribution characteristics,and the sample size.

Objective To compare the efficacy of α1 adrenergic receptor blocker,5α-reductase inhibitor or combination therapy in benign prostatic hyperplasia (BPH),and to explore the application of multi-level statistical model in assessment of BPH treatments.Methods Pragmatic clinical trials (PCT) design was used.BPH patients received drug therapy including α-adrenergic receptor blocker,5α reductase inhibitor,and combination therapy were followed up for 4 years.Multilevel statistical model was used to compare the scores of international prostate symtom score(IPSS) and BPH qality of life scale(QLS) among the 3 therapeutic regimens.Results The intra class correlation coefficients of I-PSS and BPH-QLS were 0.6136 and 0.6946 respectively,which indicated that both data were hierarchical structured.During the follow-up period,scores of IPSS and BPH-QLS were improved along with the drug therapy in 3 regimens.There was curve relationship between treatment time and IPSS and BPH-QLS scores in 3 regimens (all P<0.05),and there was no significant differences in the trend of curves between the 3 regimens (P>0.05).Conclusions For BPH patients with moderate symptoms bothering the quality of life,α-adrenergic receptor blocker,5α-reductase inhibitor,or combination therapy are significantly effective in reducing symptoms and improving quality of life.There are no efficacy differences among the 3 drug therapy during the 4-years follow-up.Compared with traditional analysis,multilevel statistical model is a more suitable and precise method for assessment of BPH treatments.

Green hospital construction is a new challenge for medical industry after global sustainable development strategy was put forward. The core connotation of green hospital includes green building, green healthcare, patient safety, and doctor-patient harmony. Many countries have established green building evaluation system to deal with energy crisis. Leadership in Energy and Environmental Design (LEED), Green Guide for Health Care (GGHC) in the U.S., and Evaluation System for Green Hospital Building (CSUS/GBC 2-2011) in China have guiding signiifcance for the development of green hospitals in China. The evaluation system of green hospitals home and abroad still focuses on green building, and establishment of suitable synthesis evaluation system of green hospitals in China needs further research.

AIM: To use seven parts cortex phellodendri and one part Rhizoma atractrylodis to extract mixedly,and study mouse's pharmacokinetic parameter of berberine derived from extract. METHODS: Evodiamine was taken as the marker,HPLC was used to determine berberine content in rat plasma. RESULTS: The linear range of rat's plasma sample was within 0.006 6-0.211 2 ?g/mL,RSD was little than 10%,detection limit was 0.0033 ?g/mL.The main pharmacokinetic parameters consisted of 2 h(T_max),0.183 mg/L(C_max),10.87 h(MRT_0-24),21.562?4.448(MRT_0-∞). CONCLUSION: Berberine in combination of cortex phellodendri and Rhizoma atractylodis can be quickly absorb and achieve the peak value,but metabolize slowly.

The violence behavior is a kind of aggressive behaviors or attempt to hurt another person psychologically,physically or in other forms.Recently,violent incidents occur more and more frequently,and especially among teenagers.A number of concerns on violence continue to rise,and interpersonal violence is the most concerned type.Perpetrators are violence implementers who determine the occurrence and outcome of violence.Many studies provided the risk factors of interpersonal violence,that expounds the influence of personal level,interpersonal relationship,community background and social factors of interpersonal violence.The establishment of the socioecological risk-factor structural model which focuses on the perpetrators' indi vidual,is of great significance for the effective intervention for interpersonal violence.

Comprehensive evaluation methods are generally used to assess the population data. When we need to estimate the sample data in special situations, the impacts brought by the sampling error should be considered. Due to lack of the accurate measurement for the sensitivity and stability in the comprehensive evaluation methods, sampling errors usually cannot be estimated in the sampling research. Monte Carlo simulation was used in this article to solve the probability of the ordering results, and the matlab programs were presented. Based on the simulated results, we change the conventional “absolute conclusion” of comprehensive evaluation methods to “probability results” for the sample data, and put forward a new sorting and ranking method for the results of comprehensive evaluation.
