Objective To describe the prevalence and distribution of anxiety disorders among people aged 18～65 yrs in Liaoning Province. Methods 15 518 subjects in 7 200 families aged 18～65 yrs were randomly selected from 3 cities and 3 counties by multi-stage stratified random cluster sampling.They were assessed for DSMⅢ-R diagnoses by face to face interview with Composite International Diagnostic Interview(CIDI-1.0). Results There were 13 359 subjects had finished the survey,and the response rate was 86.09%.The 2-week,12-month and lifetime prevalence of anxiety disorders were 2.22%,4.60% and 7.21% regulated by Liaoning provincial population in 2000,and1.91%,3.97%and6.32% regulated by countrywide population in 2000.The major disorders were specific phobia and agoraphobia,and their lifetime prevalence were 3.80% and 3.04%,respectively.The people with higher prevalence were females,aged 25~55,with lower educational and economic level. Conclusion Anxiety disorders become a serious public health problem in Liaoning province.Prevention measures should be taken among people with high risk.

Objective To investigate the correlation of CYP2D6 gene polymorphism and serum tamoxifen (TAM) and its active metabolites (4-hydroxy tamoxifen,4-OH-TAM) in terms of prognosis of breast cancer patients.Methods The oral mucosas and serum were obtained from 200 breast cancer patients receiving oral TAM from Jan 2008 to Oct 2010.Real-time RT-PCR was used to determine CYP2D6* 10 gene polymorphism.The relationship between CYP2D6* 10 gene polymorphism and clinicopathological features and prognosis was assessed by Chi-square test and Cox proportional model.Serum TAM and 4-OH-TAM concentration were determined by liquid chromatography-trap mass spectrometry (LC-MS).Results Of 200 breast cancer patients,CYP2D6 * 10/* 10 homozygotes were found in 94 cases (47％),CYP2D6 wt/wt wild type in 48 cases (24％) and CYP2D6 wt/* 10 heterozygote in 58 cases (29％).The concentration of serum 4-OH-TAM in patients with CYP2D6 wt/wt wild type and wt/* 10 heterozygote was significantly higher than that in patients with CYP2D6 * 10/ * 10 homozygote (F =4.31,P =0.01).CYP2D6 gene polymorphism was not related to clinicopathological features (P ＞ 0.05).Logrank test showed that patient's disease-free survival with mutational CYP2D6 (mean,47.2 months) was significantly shorter than that in patients without mutational CYP2D6 (mean,51.2 months) (P =0.018).Cox proportional model showed that CYP2D6 genotype was related to disease-free survival (HR =2.755,95％CI:1.230 ～6.173,P =0.014).Conclusions CYP2D6 *10/* 10 genotype is related to curative effect of TAM on breast cancer patients,detection of CYP2D6 * 10/* 10 genotype helps improve the choice of TAM therapy.

The quality control of Chinese patent medicines containing animal-derived crude drugs is relatively difficult, because the effective constituents of most animal-derived crude drugs remain unknown. Even if there are relevant methods, they are usually qualitative, and quantitative indicators are either lacking or have poor specificity. This paper has proposed to use molecular quantitative technology to control the quality of Chinese patent medicines containing animal-derived crude drugs. In this study, a molecular quantitative method based on fluorescence quantitative PCR was established for the determination of Jinqian Baihua She in Jinlong Capsule. The method has good specificity, sensitivity, and repeatability. There is a good linear relationship between the content of DNA fragments and the CT (cycle threshold) value. The content of the Bungarus multicinctus-specific fragment in Jinlong Capsule is 24.1-46.6 IU·mg^-1. It is suggested that the content of the specific fragment of Jinqian Baihua She should not be less than 19.3 IU·mg^-1 as one of the quality control criteria of Jinlong Capsule. The study can provide a reference for the quality control of Chinese patent medicines containing animal-derived crude drugs.

Objective: To study the compatible stability of cyclophosphamide (CTX) and Mesna admixture for injection in 4 commonly used infusions (5% glucose injection,0.9% sodium chloride injection,fructose injection and xylitol injection) at different temperatures.Methods: An HPLC method was adopted to determine the contents of CTX for injection in 24h respectively under 5℃ and 25℃.The appearance and pH value of the admixture were investigated.Results: No significant changes of appearance, pH value or content of the admixture were found out in 24h under 5℃ and 25℃.Conclusion: CTX and Mesna admixture for injection is compatible with the 4 commonly used infusions under 5℃ and 25℃ for clinical use in 24 h.

Objective:To investigate the inhibitory effect of cytokine-induced killer cells (CIK) against implanted gastric cancer cells. Methods:Gastric cancer SGC-7901 cells were subcutaneously injected into the inguina of nude mice to establish gastric cancer model. The tumor bearing mice were randomly divided into CIK group and fibroblasts group,in which mice were subcutaneously injected with fluorescence dye SP-DiI labeled CIK and fibroblasts HFL-I cells,respectively. Distribution of CIK and HFL-I cells in different tissues of gastric cancer bearing mice were observed. Meanwhile,tumor volume was measured after different treatments and tumor inhibitory rate was calculated. Tumor necrosis areas in different groups were observed. Results:SP-DiI labeled CIK was mainly located in the gastric cancer tissues 10 d after injection,and was hardly detected at the injection sites,liver,spleen and lung tissues (P
