An improved everted gut sac method was applied to the study of prescription compatibility effect on the major components in Danshen extracts. With the separation and detection by HPLC-ECD, 5 major peaks could be detected in intestinal absorbed solution after prescription administration. Following the identification by HPLC-MS/MS, peak 2, 3, 4, and 5 were rosmaric acid, lithospermic acid, salvianolic acid B, and salvianolic acid A, respectively, which also confirmed with reference standards of those components. Through paralleling substance identification, peak 2, 3, 4, and 5 could be found as the major components in Danshen extracts, except Salvianolic acid E which is undetectable in intestinal solution. The contents of peak 2, 3, and 4 did not show difference before and after compatible prescription administrated, where the peak 5 had a significant increase in the same process. Those results revealed that peak 5, salvianolic acid A, might lead to an increasing pharmacological effect after prescription compatibility.

Objective To examine the occupational stability,training needs and capacity building requirements of the general practitioners purposely trained to work in rural communities,for improvement of policies regarding their training and issues related. Methods There counties were selected by stratified random sampling, where general practitioners graduated from such training completed an anonymous questionnaire. Focus group interviews were made to officials of the local Health and Family Planning Commission,those of primary healthcare institutions,and general practitioners themselves. Results The of the 190 valid questionnaires recovered, male accounted for 34. 2% and female 65. 8%. These general practitioners were mostly satisfied with their working environment, social status, work stress and job achievement,yet with lower satisfaction with their salary and availability of medical devices. Consideration of resignation was reported by only 5. 3% of them,with more males than females. As high as 63. 2% of them prefer to work in hospitals of county level. 91. 1% of them held it as necessary to participate in standard resident training,and 98. 4% held it as necessary to have on-job training. 94. 7% of them have participated in further education to gain a bachelor degree in medicine. Conclusions These doctors were found with high stability to work in rural communities and low turnover intention. Further studies are required to encourage these general practitioners to serve rural communities in a long term, and to improve the standard resident training mechanism,and their career development.

Objective To explore the functional orientation of township hospitals in developed areas to achieve goals of the ongoing health reform.Methods Two rounds of Delphi consultation was made among 18 experts from around the country to learn the degree of importance of every function.Results The experts' average seniority of service in their fields was 23.28±10.41 years.The positivity coefficients of the two-round consultation were 100%.Kendall' S coefficients of the two-round consultation were 0.226 and 0.265 (p<0.01).These data are of statistical importance,suggesting consensus among these experts and the consultation meeting the needs of forecast.In these consultation,seven class-1 functions and and 27 class-2 functions were determined.Medical services and public health services account for similar proportion of work of township hospitals.Conclusion The functional orientation was feasible and forward looking,for reference of township hospitals in developed areas.

Objective To analyze functioning and disability, unmet needs and the service for people with disabilities in Shenzhen, Guangdong, China. Methods Based on International Classification of Functioning, Disability and Health (ICF) and World Report on Disabil-ity, the theoretical framework had been constructed, and the unmet needs and service status for people with disabilities in Shenzhen in 2015 had been statistically analyzed. Results For the statistics of disability by categories, physical disability composed of 42.5%, speech disability composed of 1.5%;people with severe and extremely severe disabilities composed of 52.8%;Futian District composed of 19.7%, Yantian District composed of 2.2%;people aged 0 to 18 years composed of 17.4%, and people aged over 60 years (27.0%) were the larger group. For the unmet needs of people with disabilities, 25%needed rehabilitation therapy, 18.8%needed functional training, 23.2%needed assis-tive devices, and 32.9%had no need. For rehabilitation sevice in Shenzhen, 24.4%received rehabilitation therapy, 17.4%received function-al training, 20.4%received assistive devices, and 37.6%did not receive any service. For the barrier-free reconstruction, 4.6%needed bath-room reconstruction, and 0.7%needed internet access screen software. Conclusion The status of functioning and disability, unmet needs and service development of rehabilitation in Shenzhen had been analyzed. There was still a gap between unmet needs and services of rehabilita-tion. It recommended to construct precise services delivery based on unmet needs, improve the full coverage and quality of service of reha-bilitation.

As an essential trace element in living organisms, copper is actively involved in normal physiological processes in various systems and is maintained at low level to achieve copper homeostasis. Copper homeostasis, once being disrupted, would induce cell death, and this new form of cell death is known as copper death. In recent years, copper death has been increasingly recognized as an important factor mediating the onset and progression of central nervous system (CNS) diseases. Therefore, we review the pathogenic mechanism of copper death in CNS diseases, as well as its therapeutic strategies so as to deepen the understanding of researchers.
