Infrastructure of radiation oncology in China: a national survey for development and allocation of radiotherapy equipment during the 14 th Five-Year Plan period / 中华放射肿瘤学杂志

Objective:To investigate the current status of radiotherapy personnel and equipment in China, and to provide data basis for scientific allocation and effective use of radiotherapy equipment during the 14 th Five-year Plan period. Methods:From October to December 2020, a group of experts from China Association of Medical Equipment carried out an online questionnaire investigating the basic situation of radiotherapy in China, and the contents of the survey include radiotherapy centers, professional personnel, equipment, technology, equipment utilization rate, forecast of personnel and equipment in the next five years, etc. The data were reviewed by provincial medical societies/associations.Results:There were 1538 radiotherapy centers and 32978 radiotherapy professionals in Mainland China, including 18966 radiotherapy physicians, 4475 physicists and 9537 technicians. There were 2139 linear accelerators, 57 cobalt 60 accelerators, 457 afterloaders, 6 proton/heavy ion machines, 1034 conventional 2D simulators, 1208 CT simulators, and 89 MR simulators. 1459 centers can provide 3D conformal radiotherapy, 1256 centers can deliver intensity-modulated radiotherapy, 514 centers can offer volumetric modulated arc therapy, 422 centers can provide brachytherapy. According to the estimated data reported by the participating centers, in the next five years, the demand of professionals and machines will be increased by 4868 radiotherapy physicians, 2078 physicists and 3796 technicians, and 994 linacs, 896 CT simulators, 313 MR simulators and 54 proton heavy ions.Conclusions:The radiotherapy industry in China grows fast. During the 14 th Five-Year Plan period, the radiotherapy industry still has strong market demand as well as increase demand of personnel and equipment. Strengthening the market competitiveness of domestic radiotherapy enterprises, improving the equipment utilization rate in primary hospitals, providing comprehensive and systematic training and promoting standardized clinical application can resolve the issues of the lack and unbalanced distribution of radiotherapy resources, and maintain the fast and sustainable development of radiotherapy in China.

Chinese medicinal materials industry during the 14th Five-Year Plan period: trends and development suggestions / 中国中药杂志

This study steps through the future perspectives and gives the development suggestions of Chinese medicinal materials(CMM) industry by presenting the characteristics and open problems during the 13 th Five-Year Plan period. The development of CMM industry presents the following trends:(1)the development of Dao-di herbs speeds up with the increasing demand for high-quality CMM;(2)the mismatch between supply and demand is aggravating, which presses for supply-side structural reform;(3)ecological planting will become the core mode of production and bolster rural revitalization;(4)the demand for CMM with both medical and edible values keeps growing, and the antibiotic-free feed policy brings significant opportunities;(5)the "Internet Plus CMM" wave emerges, which promotes the construction of traceability system. Finally, we put forward the following suggestions for the sustainable development of CMM industry:(1)optimizing the layout for the production of Dao-di herbs according to local conditions;(2)strengthening the commercialization of the seeds and the breeding, multiplication, and extension of CMM to accelerate the realization of specialized seed production, mechanized seed processing, localized variety layout, and county-based unified seed supply;(3)ensuring the safety of pesticide use and accelerating the registration of special pesticides;(4)promoting both theoretical and practical research on ecological production of CMM;(5)publicizing the demonstration and popularization of CMM traceability system. Overall, significant progress has been achieved in the CMM industry during the 13 th Five-Year Plan period, and this industry is in a critical stage of high-quality development, facing both challenges and opportunities.

Discussion on the strategy of the development of the cancer basic research in a cancer hospital under the new situation based on the supporting guidance of the NSFC / 中华医学科研管理杂志

Objective:According to the characteristics of basic science research in the field of cancer during the 14 th five-year plan period, the scientific construction pattern which is available for the development of basic research in a cancer hospital is explored. Methods:A series of policy adjustments and the directions of research and development promulgated by the National Natural Science Foundation of China (NSFC) which supports basic and applied basic research in various scientific fields during the middle and late period of the 13 th five-year plan and the beginning year of the 14 th five-year plan is expounded and analyzed. Results:The cancer basic research will be more systematic, interdisciplinary and clinical fusion, and the clinical application of basic research achievements will be the key purposes under the new research pattern.Conclusions:The construction of basic research in the hospital should be combined with the characteristics of the new research pattern. The overall scientific and systematic layout of the research should be strengthened, the interdisciplinary research model should be established, and the clinical applied basic research should also be encouraged and supported, as well as the efficiency of transformation of basic research achievements needs to be further improved.

Vertebroplastia percutânea nas fraturas vertebrais por osteoporose: avaliação a longo prazo / Percutaneous vertebroplasty for vertebral osteoporotic fractures: long term analysis

OBJETIVO: Avaliar a resposta terapêutica a longo prazo da vertebroplastia percutânea para o tratamento da dor decorrente de fraturas de corpo vertebral por osteoporose. MÉTODO: Foram realizadas 26 vertebroplastias percutâneas em 15 pacientes com dor por fraturas osteoporóticas de corpo vertebral, durante o período de julho de 2001 a maio de 2004. Imediatamente antes e após o procedimento, foi aferido o grau de dor de cada paciente com base em uma escala verbal álgica entre zero e dez. Esta aferição foi repetida a longo prazo, com um ano de intervalo, sendo ainda investigada a satisfação do paciente, a deambulação e as atividades diárias (escalas de cinco pontos). RESULTADOS: Observou-se que a maioria dos pacientes (n=13) apresentava escala verbal de dor entre 8 e 10 antes da vertebroplastia. Houve importante redução álgica no dia seguinte, com 9 pacientes apresentando ausência de dor e três pacientes escala álgica entre 1 e 4 (p<0,001). No acompanhamento a longo prazo, com um ano de intervalo, a melhora dos sintomas se manteve, sem diferença significativa na escala de dor, na deambulação e nas atividades diárias. Quando questionados se fariam novamente este tratamento no caso de nova fratura vertebral, 14 pacientes responderam que sim. CONCLUSÃO: A vertebroplastia percutânea pode ocasionar importante melhora da dor em pacientes com fraturas osteoporóticas de corpo vertebral, quando bem selecionados, com boa resposta a longo prazo.

OBJECTIVE: To assess the long-term efficacy of percutaneous vertebroplasty for the treatment of pain resulting from osteoporotic vertebral fractures. METHOD: 26 percutaneous vertebroplasty procedures were performed for osteoporotic vertebral fractures in 15 patients during the period between July 2001 and May 2004. Before and after the procedure, a 10-point scale of pain was obtained. These scale was repeated at long-term follow up in two different moments after the procedure with one year interval. During these moments, the satisfaction, ambulation and ability to perform activities of daily living (five-point scale) were also analyzed. RESULTS: The majority of patients (n=13) presented the 10-point pain scale between 8 and 10 before the percutaneous vertebroplasty. After the procedure, there was important improve of the pain, and nine patients presented zero point-scale and three patients between 1 and 4 (p<0.001). At long-term follow up with one year interval, there was no significant difference between the pain scale, the ambulation and the ability to perform activities of daily living. Fourteen patients reported a future willingness to undergo the procedure for treatment in case of a new compression fracture. CONCLUSION: Percutaneous vertebroplasty can be a useful procedure for the treatment of pain and disability after secondary osteoporotic vertebral fractures with durable results in selected patients.
