OBJECTIVE:To establish a method for the determination of related substances in Vildagliptin tablets. METHODS:HPLC method was adopted. The determination was performed on Xterra MS C18 column with mobile phase consisted of [phosphate buffer-water-acetonitrie-methanol(400 : 600 : 15 : 15,V/V/V/V)]-[phosphate buffer-acetonitrile-methanol(400 : 450 : 150,V/V/V)](gra-dient elution)at the flow rate of 1.2 mL/min. The detection wavelength was set at 210 nm and column temperature was 35 ℃. The sample size was 10 μL. RESULTS:The linear ranges were 18.80-188.0 μg/mL for impurity A(r=0.9995),22.64-226.4 μg/mL for impurity B(r=0.9996),21.74-217.4 μg/mL for impurity C(r=0.9997),19.12-191.2 μg/mL for impurity D(r=0.9998). The limits of detection were 4.18,2.68,1.12,1.34 μg/mL,respectively;RSDs of precision,stability and reproducibility tests were lower than 3%;the recoveries of impurity A,B,C and D were 97.9%-103.1%(RSD=2.01%,n=9),98.8%-104.1%(RSD=1.93%,n=9),98.0%-103.6%(RSD=1.81%,n=9),100.8%-104.1%(RSD=0.98%,n=9),respectively. CONCLU-SIONS:The method is simple and accurate,and can be used for the determination of related substances in Vildagliptin tablets.

Objective:To establish a method for the determination of the related substances in ticagrelor tablets. Methods:An op-timal HPLC method was set up and a Hypersil BDS C18 column (200 mm × 4. 6 mm, 5μm) was adopted. The mobile phase A was wa-ter (pH was adjusted to 3. 0 by phosphoric acid) and the mobile phase B was acetonitrile with gradient elution at a flow rate of 1. 0 ml ·min-1 , and the detection wavelength was set at 255 nm. The column temperature was 30 ℃, and the volume of injection was 5 μl. Results:The resolutions between ticagrelor and the adjacent impurity ( impurity E) , and between ticagrelor and the known impurities were all greater than 1. 5. Impurity A-H all had a good linear relationship within the range of 2. 0-20. 0 μg·ml-1(r>0. 996 0). The average recovery was 99. 8%, 98. 1%, 96. 5%, 101. 2%, 99. 3%, 100. 7%, 102. 1% and 103. 4% with RSD of 1. 02%, 0. 88%, 1. 13%, 0. 56%, 0. 79%, 1. 11%, 0. 63% and 1. 39%, respectively(n=9). Conclusion:The method is reproducible and accurate in the determination of the related substances in ticagrelor tables.

Application ofmolecular diagnostic technique has shown greatpotential and technical advantages in the diagnosis and treatment of cardiovascular disease ( CVD ) .It can be used toscreening , diagnosis , treatment and prognostic evaluation of CVD disease .Early screening helps to notice the risk of the disease, make us take appropriate measures to reduce the health care costs and improve outcomes .To achieve the highest diagnostic efficiency by applying different molecular diagnostic strategies in different diseases.In term of treatment, molecular diagnostic technologies are mainly used in the drug discovery , personalized drug therapy and treatment options; In addition, prognostic assessment of CVD is also an important development direction of molecular diagnostic technique .However, there are severe challenges remained in applying molecular diagnostic techniques in CVD disease , such as the basic andclinicalapplication research and the quality control , etc.

Objectives:To investigate the efficacy of STI/HIV preventive intervention on prostitutes and to discuss the ethical issues.Method:Anonymous questionnaire survey was used to collect the KAB data before and after health education. The data were analysed by using SPSS10.0 software. Results:140 prostitutes received health education and 87 prostitutes were evaluated after intervention.Both the condom knowledge and the condom use during sex increased significantly after health education(P

Objective To explore the treatment to craniocerebral injury.Methods 6 patients suffered from serious, developing head injury with epidural and subdural hematoma were processed by cone socket hematoma drainage in ward before hematoma was eliminated.Results Hematoma drainage can be performed within 20 min after hospitalization. No case died and no infection occured. The score of Glasgow Outcome Scale were Ⅴ(2 cases), Ⅳ(2 cases),Ⅲ(1 case) and Ⅱ(1 case) 3 months after operation.Conclusion Cone socket hematoma drainage in ward is a good method to treat craniocerebral injury.

We collected 22 cultivated population of Lonicera japonica from 17 areas. The characteristics of non-glandular hairs were observed and measured by the scanning electron microscopy. The principal components analysis and correlation analysis were conduct based on length and density of L. japonica. The results showed a significant negative correlation between length and density of non-glandular hairs, and the characteristics of non-glandular was not corrrelated significantly with latitude. The correlation results indicated that the density was a key to separate "Damaohua" and "Jizhuahua". The contribution of climate and soil was important to the cultivated population. This reminded that the characteristics of non-glandular hairs were affected by environmental and genetic interaction.

Sixty-three morphological traits from 743 specimens of the 41 taxa within the cultivated Lonicera japonica were observed and measured, such as the height of plants, the length of leaf, the width of leaf, the length of anther, the alabastrum's number of one branch, the color of alabastrum and so on. A numerical taxonomy is presented by using the cluster analysis, principal components analysis (PCA) and factor analysis. Sixteen of 63 characters were screened by means of PCA and used for cluster analysis of 41 taxa with the method of Ward linkage and average euclidean distance. The cluster analysis showed that the 41 taxa could be divided into 5 groups when the Euclidean distance coefficient was 11.84. The factor analysis indicated that the shape of leaf, color of alabastrum, the pilosity and color of twiggery were of significance for the cultivated L. japonica classification. The results of this study will be a base for the core collection and breeding of L. japonica.

OBJECTIVE To study the bactericidal efficacy of glutaraldehyde,and its stability and change in pH value.METHODS The carrier quantity bactericidal test,field mimic bactericidal test,stability test,pH value detection,periodical biological surveillance and follow-up investigation of hospital infection were used.RESULTS After using of 20 000 mg/L of neutral glutaraldehyde on Candida albicans(ATCC 10231),Pseudomonas aeruginosa(ATCC27853),Escherichia coli(ATCC 25922) and other 3 clinical isolates separately for 3,5,and 10 min,the average killing rate was 97.90%,99.83% and 100.00%;on the field mimic bactericidal test with MRSA contaminated gastroscope,the average killing rate was 87.84%,99.50%,and 100.00%,respectively.The concentration of disinfectant after storaging 14d on 54℃ was decreased,only loss 1.46%,the concentration loss of disinfectant on using endoscope 5,7,and 14d after disinfection was 2.64%,0.69% and 0.94%,respectively.The value of pH was decreased from 7.22 to 6.00,6.50,and 6.20.The qualification rate of 260 various endoscopes after surveillance was 100.00%.Their was one of hospital infection happened among 3 200 patients after endoscopy which were followed up.CONCLUSIONS The results show that,only under the following circumstances,namely the concentration of glutaraldehyde being no less than 20 000mg/L and the action time being no less than 10 min,timely alteration of glutaraldehyde,and regular biological and concentration monitoring could the disinfection of endoscope be qualified so that hospital infection can be prevented,and medical dispute may be put to an end.

Objective This study aimed to establish an anatomic basis for the microscopic surgical anatomy of the cavemous sinus via the extended transsphenoidal approach.Methods Simulated surgery via extended transsphenoidal ap-proach was performed on seven adult cadaver heads with red--colored latex injected arteries.The cavernous segment of the ICA and its branch vessels and its relationship with cranial nerve were exposed and its anatomic parameters were measured under microscope.Results The tuberculum sellae,clivus,sellar base,ICA prominence,and optic nerve prominence are the important bone landmarks to define the surgical area.The average of the extent of bone removal of extended transsphe-noidal approach is 37.6 mm(range:28.7 mm～44.0 mm).Conclusions The bone removal from sellar base to the media edge of the foramen rotundum and over the ICA prominence can effectively expose the entire unilateral cavernous sinus.The microscopic cavernous sinus surgery via the extended transsphenoidal approach is an optimal surgical approach for the le-sions that invade the cavernous sinus from sella.
