Since its founding,the Management Center of Shenzhen Public Hospitals,on the basis of summarizing and inheriting reform outcomes in the past,has been working on to streamline the relationship between the government,public hospitals and the society in line with the general reform requirements of the stateupholding public welfare nature,motivating and ensuring sustainability.The center carries out a general reform covering the hospital management system,operating mechanism,supervision mode,and service mode.This way the center has built a set of contemporary hospital management system fitting Shenzhen' s conditions,encouraging hospital operations to better embody the interests of the government,medical workers and the society,and to better cover quality,equity and efficiency,thus effectively improving the management performance and services of the hospitals in question.

In the development of primary care system,Shenzhen has called into play the model of hospital-centering,and made it a link to build a new urban medical service system of clear-cut levels,rational division of responsibilities and mutual benefit.This design provides the primary care with a good credit,a reasonable medical insurance system,and appropriate technical support.Furthermore,it improved the efficiency of unban health resource allocation and utilization and alleviated residents' burden of medical costs.This study aims to introduce the measures and advantages in the implementation of the primary care system in Shenzhen,analyze the problems found in Shenzhen' s community health service system and make recommendations for the improvement.

Shenzhen implemented the health reform on the separation of drug prescribing and dispensing.This policy abolished the drug price addition system,which interrupted the interest chain between hospitals and pharmaceutical enterprises,and curbed the over-medication and use of expensive drugs.Such a reform has lowered the average cost of diagnose and treatment,the out-of-pocket payment by those covered by social insurance,outpatient infusion and the utilization of antibiotics.To further strengthen these outcomes and maintain the momentum of this policy,Shenzhen will further improve the compensation system for public hospitals,encourage the medical staffs' work enthusiasm and implement the reform measures actively.

As requested by both central government and Guangdong provincial government on the reform to separate drug prescribing and dispensing,Shenzhen has introduced its 1 + 6 comprehensive program.Breaking through from the drug price addition system,the program stages such six measures as the health service payment system reform,the compensation system reform among public hospitals,reform of the competition mechanism between pharmaceutical distribution enterprises and hospital pharmacies,reform of drug procurement methods,investigation and punishment of commercial briberies in drug purchase,and enhanced supervision of public hospitals.The paper detailed these measures and explained these innovative practices.

This articles introduced the development of the four systems and eight mechanisms in Shenzhen's health reform,and described the implementing measures of the public hospitals reform and major mechanisms reform.It also reviewed the major achievements and challenges met in the health reform and made an outlook of the future steps in the reform.

In order to reform the medical talent evaluation system, establish evaluation systems of physician competency, and implement physician resources management systems according to work position, and the compensa-tion system which reflects the value of medical services, The basic principles and standards of different physician tiers and grades are created in Shenzhen based on literature review, expert consultation and the methods from the American Centers for Medicare and Medicaid Services ( CMS) . Some results have achieved, including medical competency as-sessment of a certain number of physicians in the pilot project ( the coincidence rate of special hospitals is higher than general hospitals, respectively 78. 9% and 44. 8% ), comprehensive personnel systems reforms in public hospi-tals, and the trial selection of medical talents. The paper also provides some implications:The cognition of all sectors of society and physician themselves should be improved, Transitional policies for position recruitment and performance pay needs further improvement. Meanwhile, the grade evaluation system of non-physicians must also be given greater attention.

With the application of high throughput sequencing and other technologies, in recent years people have found that bacteria are not only the causative factors of common breast diseases such as mastitis, but also may be involved in the occurrence and development of breast cancer. There are unique bacterial communities in the internal tissues of the breast, and their existence may be related to the incidence of breast cancer. Recent studies have found that intestinal flora may also affect the incidence of breast cancer by regulating estrogen and other pathways. Further exploration of the influence of bacteria on breast cancer will provide new ideas for diagnosis and treatment of breast cancer.

By analyzing the present development and reform experiments for public hospitals in Shenzhen,the author proposed the following directions for such a reform:1) Accelerating steps of the development strategy "One Large and One Small",to achieve a balanced deployment of local healthcare resources;2) Building a public hospitals group with reasonable resources deployment and information resources sharing;3) Advancing reforms of public hospitals,building an administrative system of public hospitals featuring separation between government functions and hospitals operations and that between hospital administration and hospital building;4) Improving the supervision mechanism for public hospitals featuring distinct rights and responsibilities and powerful regulatory practice;5) Building a scientific operation system of efficient incentives and self constraints;6) Building a service model for public hospitals featuring separation of medical service and pharmaceuticals sales and normalized system.

OBJECTIVE:To prepare Yinxingye extract pellets and study its in vitro drug release rate.METHODS:The Yinxingye extract were coated with 3 coating materials(opadryⅡ,Eudragit L30D-55 and Eudragit S 100,respectively)to be prepared into pallets by centrifugalized palletizing method;and the 3 different coated pallets were prepared into mixed pallets in an pre-designed ratio.The in vitro release of the 3 coated pallets and the mixed-coated pallets were determined by changing the pH-gradient of media(0.1 mol?L-1 hydrochloric acid,pH 5.8 PBS,pH 7.2 PBS).RESULTS:The pallets coated with 3 different coating materials released quickly in 0.1 mol?L-1 hydrochloric acid,pH 5.8 PBS and pH 7.2 PBS,and the pellets with mixed coating materials had a sustained release until a complete release within about 8 h in pH gradient-changed media.CONCLUSION:The preparation process is feasible and provides theoretic basis for industrial production.

?AIM:To compare the coherence and difference on the fundus examination made with two kinds of optical coherence tomography ( OCT): Angio-OCT and fourier domain-optical coherence tomography ( FD-OCT) .?METHODS:Using Angio-OCT and FD-OCT to measure the retinal nerve fiber layer ( RNFL ) thickness, optic parameters, and ganglion cell complexes ( GCC ) thickness from 20 subjects respectively.The coherence was tested with Pearson's correlation coefficient, the difference was tested with paired Student t testing.?RESULTS:The total correlation of the RNFL thickness, optic parameters, GCC thickness made with two kinds of OCT was between 0.7-0.8;the RNFL thickness, optic disk area etc.made with the Angio-OCT were lower than those made with FD-OCT except for the GCC thickness.?CONCLUSION: The results made with two kinds of OCT from the same subject has certain coherence, but cannot be compared directly.
