Objective To establish a new identification method of Ophiopogonis japonicus from different habitats.Methods Using 1H-NMR to get the all component information on O.japonicus,and using pattern recognitions,such as principal component analysis(PCA),partial least squares-discriiminate analysis(PLS-DA),and hierarchical cluster analysis(HCA) to analyze the data from the 1H-NMR spectra.Results The 1H-NMR-pattern recognition(PR) method could identify the samples of O.japonicus from different habitats successively.Conclusion The 1H-NMR-PR is an useful method for identification of O.japonicus from different habitats and could be used for the quality control of traditional Chinese medicinal materials.

Objective: To evaluate the third round of Zhejiang Comprehensive AIDS Response (CARES) program (nine national areas and three provincial areas) and the control effect of AIDS, so as to provide reference for AIDS prevention and control. Methods: According to the final assessment protocol of the third round of China CARES, the data of 23 assessment items which were collected from online database and field investigation for 12 response areas of Zhejiang in 2014 and 2018 were evaluated. The endemic situation and detection of AIDS in CARES areas was compared with those in non-CARES areas, in order to evaluate the achievement of Zhejiang CARES areas. Results: The rates of reaching the standard ranged from 91.30% to 100.00% in 12 CARES areas. Six indexes in leadership and innovation, fifteen (seventeen in total) indexes in HIV/AIDS control and prevention reached the standard. The items that failed included the awareness rates of AIDS and indicators in “prevention and intervention”. The rates of of reaching the standard in “publicity and education”, “monitoring and testing”, “prevention and intervention”, and “treatment and follow-up” increased from 55.56%, 79.17%, 79.76% and 65.00% in 2014 to 91.67%, 100.00%, 90.48% and 100.00% in 2018, respectively. The proportion of HIV testing people in permanent residents was 30.94% in CARES areas in 2018, which was significantly higher than 20.70% in non-CARES areas (P<0.05). The proportion of new reported HIV/AIDS in CARES areas was 50.87%, and the average increase was 4.48%, which was lower than 9.95% in non-CARES areas. Conclusion The third round of Zhejiang CARES program has remarkable achievement and plays a positive role in the prevention and control of AIDS.
