Evaporative light scattering detector(ELSD) and charged aerosol detector(CAD) methods were established in this study for the content determination of four kinds of sugars in Zhusheyong Yiqi Fumai(YQFM), and the factors affecting the accuracy of CAD methods were discussed. HPLC-ELSD chromatographic separation was performed on a Shodex Asahipak NH2 P-50 column with acetonitrile-water(75∶25)as the mobile phase, with a flow rate of 0.8 mL·min~(-1), drift tube temperature of 80 ℃. The analysis by HPLC-CAD was performed on the same column with acetonitrile-water as mobile phase for gradient elution, with a flow rate of 0.8 mL·min~(-1), a neb temperature of 45 ℃, and power function(PF) of 1.3. The samples of YQFM were detected by ELSD and CAD respectively. It was found that YQFM was composed of fructose, glucose, sucrose and maltose. The linear relationship of the two methods was good, and the recoveries, reproducibility and stability of these four kinds of sugars measured by the two methods satisfied the requirements of methodology. Both CAD and ELSD detectors were accurate and reliable in detecting saccharides components in YQFM. In addition, it was revealed in this study for the first time that the PF parameter of CAD had an important influence on the accuracy of sugar determination and acted as the key parameter of CAD method. It was also found that for CAD, a non-linear detector, there was no significant difference between the results of linear regression and logarithmic regression.

Objective: To evaluate the service competence of 99 smoking cessation clinics in Zhejiang Province, so as to provide reference for the improvement. Methods: The questionnaire, prepared by Tobacco Control Office of Chinese Center for Disease Control and Prevention, was used to investigate all the smoking cessation clinics in Zhejiang Province, to score the basic and developmental indicators, and to assess the qualified rates ( basic indicators >50 points and total scores >60 points ). Results: There were 99 smoking cessation clinics, with 52 in secondary hospitals and 47 in tertiary hospitals. The overall assessment scored from 11 to 96 points, with an average of ( 53.99±16.56 ) points. The smoking cessation clinics in secondary and tertiary hospitals scored ( 53.92±15.88 ) points and ( 54.06±17.45 ) points. The scores of basic and developmental indicators were ( 45.66±12.16 ) points and ( 8.33±5.39 ) points, with the scoring rates of 65.23% and 27.77%. The overall assessment of 43 smoking cessation clinics were qualified and the rate was 43.43%, which was 44.23% in secondary hospitals and 42.55% in tertiary hospitals. Conclusion The qualified rate of smoking cessation clinics in Zhejiang Province was 43.43%, which was similar between second hospitals and tertiary hospitals.

The purpose of this study was to investigate the feasibility of the salvianolic acids reference extract for quality control for Salvia miltiorrhiza and salvianolic acids for injection. An Agilent ZORBAX SB-C18( 4. 6 mm×250 mm,5 μm) column was used with mobile phase consisting of 0. 1% formic acid-water and 0. 1% formic acid-acetonitrile in gradient elution procedure. The column temperature was 30 ℃; the flow rate was 1 m L·min-1; and the detection wavelength was 288 nm. The content of rosmarinic acid,lithospermic acid and salvianolic acid B in S. miltiorrhiza was determined by using the salvianolic acids reference extract as control substance. The content of caffeic acid,salvianolic acid E,rosmarinic acid,lithospermic acid,salvianolic acid B,and salvianolic acid Y in the salvianolic acids for injection was also determined. The linear relationship between chemicals was good( r>0. 998 9),and the injection precision RSD was 0. 30%-0. 90%. The sexual RSD is between 1. 4% and 3. 0%,and the RSD of the reproducibility of the extract is between 2. 1% and 5. 2%. The recovery rate of the three components in S. miltiorrhiza was 96. 80%-99. 20%,and the recovery rate of the six components in salvianolic acids for injection was 88. 90%-107. 5%. The solution of S. miltiorrhiza and salvianolic acids for injection were stable within 48 h. A total of 8 batches of S. miltiorrhiza and injection were determined by the reference extract,and the difference was smaller than that measured by the monomer control. This study preliminarily verified that the salvianolic acids reference extract can be used as a substitute for the monomer control for the quality control of S. miltiorrhiza and salvianolic acids for injection.

To establish an on-line monitoring method for extraction process of Schisandrae Chinensis Fructus, the formula medicinal material of Yiqi Fumai lyophilized injection by combining near infrared spectroscopy with multi-variable data analysis technology. The multivariate statistical process control (MSPC) model was established based on 5 normal batches in production and 2 test batches were monitored by PC scores, DModX and Hotelling T2 control charts. The results showed that MSPC model had a good monitoring ability for the extraction process. The application of the MSPC model to actual production process could effectively achieve on-line monitoring for extraction process of Schisandrae Chinensis Fructus, and can reflect the change of material properties in the production process in real time. This established process monitoring method could provide reference for the application of process analysis technology in the process quality control of traditional Chinese medicine injections.

Objective To learn the smoke-free environment and smoking status at or below county-level governments of Zhejiang Province, and to promote a smoke-free government.Methods By multi-stage random sampling method, 4 cities were selected in Zhejiang Province, then 4 counties were selected in 4 cities, finally12 governments were selected in 4 counties.With the methods of field observation,interview and questionnaire survey,smoke-free environment and smoking behavior , tobacco related knowledge of civil servants were investigated.Results A total of 12 governments and 405 civil servants were investigated.The smoke-free environment of 12 governments were relatively well.The total smoking rate of civil servants was 17.78%, and the highest was 26.67% in Jiande City, and the lowest were 9.00% in Zhuji City.For the civil servants ,male(26.62%), aged 50-(40.74%),divorced or widowed(40.00%),graduation of technical secondary school (33.33%),cadre of section rank(57.14%),above 20 years' work(28.81%),smoking anywhere at home(50.00%), smoking in certain areas at work(22.95%)were significantly higher.The rate of cognition on the hazards of smoking was lower among the smokers than that of non-smokers (P<0.05).The rate of agreement on MPOWER tobacco control strategies and smoking bans in public places were lower among the smokers than that of non-smokers (P<0.05).Non-conditional logistic regression analysis showed that age of 30-39(OR=9.87,95%CI:1.45-67.29),50-(OR=9.87,95%CI:1.45-67.29), smoking anywhere at home(OR=12.28,95%CI:2.95-51.18),and smoking in certain areas at home(OR=6.57,95%CI:3.07-14.08) may be the risk factors about smoking behavior.Conclusion The situation of smoking control at or below county-level governments in Zhejiang Province was good, and smoking rates has declined.But tobacco related knowledge and behavior of civil servants were relatively insufficient.Aiming at the problems found in the investigation, it is necessary to strengthen education on smoking control among civil servants, and to promote a smoke-free government.
