RESUMO
Objective:In order to allow the large instruments to play the greatest role in scientific research management and technology coverage.Methods:Texts review of the opening and sharing of large-scale instrument platforms of domestic and foreign universities and scientific research institutions was conducted, combined with the experience of more than 10-year operation of the technology platform of State Key Laboratory of Natural and Biomimetic Drugs of Peking University.Results:There are particular problems in the opening and sharing of large-scale instrument technology service platforms at this stage. Through building the hierarchical management of large instruments and equipment, building an efficient and flexible shared management information system, introducing high-level instrument management and high-level talents, and strengthening the security management of the shared platform, State Key Laboratory of Natural and Biomimetic Drugs of Peking University realized the opening and sharing of large-scale instrument technology service platforms. We consider that the current large-scale instrument technology service platforms of universities and research institutes are necessary and feasible to be shared. It is greatly significant to improve the utilization rate of scientific research instruments and to innovate to the ability of the whole society.Conclusions:At this stage, efficient management, system capabilities, and team building can effectively promote the opening and sharing of large-scale instrument technology service platforms.
RESUMO
Objective:In order to study the necessity of introducing PhD students into the large-scale instrument platform and how to make them play a better role in work through management.Methods:The status of technicians in large-scale instrument and equipment platforms of domestic and foreign universities and scientific research institutions were investigated; combined with the experience of more than 10 years of operation of the technology platform of State Key Laboratory of Natural and Biomimetic Drugs of Peking University, the analysis was carried out.Results:In recent years, the large-scale instrument platforms of major universities and scientific research institutions have strengthened the introduction of high-level talents and the construction of the team. Maintain the stability of the instrument service staff through management measures such as rank promotion and salary enhancement.Conclusions:High-precision instruments are the foundation of the instrument technology platform, and well-educated talents are the core of the instrument technology platform. Only when more PhD students join the technology platform, can the high-precision instruments and equipment exert their maximum functions and promote scientific research.
RESUMO
Objective To investigate the potential benefits of hepatic resection for patients with hepatic metastasis of gastroenteropancreatic neuroendocrine tumors.Methods A search in Cochrane Library,PubMed,Medline,Embase,CBM,Wanfang Databases for identifying randomized trails.Criteria for inclusion were established based on validity criteria by Cochrane Methods Group on screening and diagnostic tests,and correlated indexes of 10 articles including 1 567 patients were extracted for Meta-analysis.Results Compared with non-surgical treatment group,the 3-year survival rate (OR:0.07,95 ％ CI:0.02,0.22 ; Pheterogeneity =0.93,P ＜ 0.00001),the 5-year survival rate (OR:0.19,95 ％ CI:0.15,0.24 ; Pheterogeneity ＝ 0.11,＜ 0.00001) were significantly increased in the surgical group.Conclusions Surgical resection is the preferred treatment of gastroenteropancreatic neuroendocrine tumors in patients with liver metastasis.Surgery is safe and effective,furthermore it takes the advantages of significantly extend the surgical live time.
