Medical science and technology are important as they concerns people's life. Innovation of medical science and technology is therefore significant for the development of the science and technology. This article discussed the current situation of medical science and technology in China,and analyszed its opportnities and challenges. In addition, strategies for its development during the Twelfth Five-year Plan period are proposed, namely, to develop HLS, construct the innovative systems of medical science and technology, and to promote the coordinated development of the medicine and science and technology.

AIM: To compare two methods of HPLC-MS/MS and MEIA to monitor the tacrolimus concentrations for organ transplantation patient.METHODS: After developing and validating the HPLC-MS/MS method to determine the concentrations of tacrolimus,the tacrolimus samples were quantitated by two methods of HPLC-MS/MS and MEIA,respectively.Evaluate two methods by statistical analysis of quantitative results.RESULTS: The mean concentration were(4.86?0.46) ng/mL by HPLC-MS/MS and(5.52?0.43) ng/mL by MEIA.The coefficient correlation of two methods was 0.8771,and the two methods have good correlations in statistics.The mean concentration ratio was(90.3?5.3)%.CONCLUSION: The HPLC-MS/MS method is a more precise method for to determining the effective concentration of tacrolimus,which is suitable for daily TDM.

The article reviewed the current status, reform measures and progress of the tiered medical services in Zhejiang province, and analyzed main roadblocks in such a system.Proposals made in the paper include such reform measures as further expanding quality medical resources of better talents and equipments to enhance primary medical institutions;forming the gatekeeper practice featuring firstvisit at community health centers with enhanced primary capabilities;insisting on joint reform of medical treatment, medical insurance and drugs, promoting the development of tiered medical services and utilization efficiency of medical resources in the province.

Since the launch of the comprehensive public hospital reform in Zhejiang Province, the price of medical services has been adjusted, and the charging structure of medical services has been improved. Likewise, medical insurance policies have been optimized. Through several price adjustment strategies, such as the“loosen-re-strain” policy, the labor of medical personnel has been better valued, the operation of public medical institutions has been stabilized, and the allocation of medical resources has been optimized. Hence, this paper aims to measure the achievements and drawbacks of the medical service price adjustments by analyzing the various strategy. It is suggested that the comprehensive public hospital reform should be further intensified via the advancement of coordination of healthcare, medical insurance and medicine, the exploration of new procurement mechanisms for drugs and medical equipment, the establishment of dynamic adjustment mechanisms for medical service pricing, the exploration of new management mechanisms for medical services, and the strengthening of medical service supervision.

Based on the ongoing health reform and Wenzhou's economic and social developments,this article made a complete analysis on the policy packages initiated by Wenzhou government in August 2012,in an effort to encourage and involve private capital to launch medical institutions.These policies and measures released take into account the policy and legal environment for private capital in medical sector in China,and target the demands of deepening health reform and shortage of health development funding.Such efforts of Wenzhou are designed as breakthroughs in terms of market access,doctors mobility,return on investment,health insurance and fiscal policy.

Community Health Committee (CHC), an innovative public participation mechanism of grassroots health service management, established a bottom-up communication channel between the public and government to communicate health related problems and opinions, and set up a grassroots community health services supervision system. The rural residents were endowed with opportunities to take part in grassroots health care decision making and management by CHC. CHC changed the top-down model of traditional health management, improved the grassroots medical services, and increased governance capability of local government We introduced the CHC practice in Zhejiang project counties, exhibited the primary effects and experience of this pilot program, and explored new mechanism and model for rural community residents to participate in grassroots health service management

Objective To study the correlation of HBV infection pretransplantation and posttrans-plantation and HCMV recurrence after liver transplantation (LT). Methods We reviewed historical patient medical records of LT patients in recent two years in our hospital. All the patients were divided into HBV in-fection group and a control group based on a peripheral blood HB antigen assay before LT. The HBV infec-tion group was divided into HBV reactive infection group and HBV non-relapse group. HCMV antigen pp~65 was detected by immunohistochemical methods. HB antigens and antibodies were detected by time-resolved fluorescence immunoassay, and liver enzyme levels were detected by conventional methods. Results Com-paring two groups of patients, pp65-positive rates of LT patients with HBV infection and control group pa-tients were 84.3% and 57.9% respectively (P=0.024). While in HBV recurrence infection group and non-recurrence infection group, the incidences of HCMV recurrence were 90.9% and 83.3% (P=0.843). The changes in the liver transaminases level in both groups have no statistical significance (P>0.05). Conclusion Pretransplantation HBV infection may increase the incidence of HCMV recurrence. Posttrans-plantation HBV reactive infection, however, may not increase the incidence of HCMV reactive infection. Meanwhile, compare with either HBV infection or HCMV infection alone, co-infection may not serious in liv-er enzymes levels.

Objective To improve the quality standard of compound Chaihu tea. Methods Pupleuri Radix, Puerariae Lobatae Radix and Forsythiae Fructus were identified by thin layer chromatography (TLC).HPLC method was used to determine the content of puerarin.The determination was performed on a Shimadzu VP-ODS-C18column (250 mm×4.6 mm,5μm) with the mobile phase of methanol-0.2% H3PO4(23:77).The flow rate was 1.0 mL·min-1, the column temperature was set at 30 ℃ and the detection wavelength was 250 nm. Results The TLC spots were clear and well-separated without negative interference.The good linear correlation existed within the range of 1.340 8-56.632 8μg· mL-1 for puerarin (r=0.999 9, n=6) and the average recovery was 102.98% with RSD being 1.48% (n=6). Conclusion The method is simple and accurate.It can be used for quality control of compound Chaihu tea.

Covered in the paper are the policies and progress of the county-level public hospital reform in the province,and a summarized analysis of the self-appraisal reports and hospital reform statements submitted by the health authorities and up to 300 hospitals in 79 counties of the province.As found in the papers,the ongoing reform in Zhejiang is focused on reforming the business models in place,seeking breakthroughs from the zero mark-up policy on drug sales,in addition to such policies as reducing drug costs,adjusting medical service pricing,financial subsidies,and medical insurance payment reforms.Despite the initial success,further policy studies are needed in terms of internal management,upper and lower linkage,and personnel incentives.

The paper covered the initial success of Zhejiang province in furthering its development of a basic healthcare system in alignment of social and economic growth. Such progress has been achieved by adhering to the principles of coordinated arrangement,highlighting key points and step-by-step progress. Also presented are the methods and experiences of the province in its reform and perspectives for furthering the ongoing reform.
