RESUMO
Over the past decade, remarkable progress has been made in prevention and control of endemic diseases in China through implementation of the 12th and the 13th Five-Year National Plans for Prevention and Control of Endemic Diseases and the Three-Year Action Plan for Special Prevention and Control of Endemic Diseases. Based on the latest monitoring data of endemic diseases and the evaluation results of the control and elimination of endemic diseases of the 13th Five-Year Plan, this paper analyzed current main problems in prevention and control of endemic diseases in China, focusing on implementation of prevention and control measures for iodine deficiency disorders, endemic fluorosis, and endemic arsenicosis, as well as the treatment and management of patients. Accordingly, corresponding countermeasures and suggestions are put forward from three aspects, including prevention and control mechanism, implementation of prevention and control measures, and scientific research, so as to provide scientific basis for the country and various regions to consolidate the achievements of prevention and control of endemic diseases and accurately implement the prevention and control measures of endemic diseases.
RESUMO
Objective:To understand main problems existing in the construction of advanced stroke centers in China and put forward solutions, for reference in promoting the standardization construction of advanced stroke centers and improving the efficiency of acute stroke treatment.Methods:The data were derived from relevant data of on-site export guidance in the construction of advanced stroke centers at 175 tertiary hospitals from 2020 to 2021, and the scores of on-site evaluation indicators for the establishment of stroke centers and their formal approval were compared and analyzed. Based on on-site investigation and expert consultation, the common problems existing in the construction of advanced stroke centers were summarized. All data were analyzed by descriptive analysis, the scores of on-site evaluation indicators were expressed by ± s, and paired t test was used for comparison between groups. Results:Compared with the total score(693.04±72.06) of on-site evaluation at the stage of project launch, the total score(747.94±78.10) of on-site evaluation for formal approval of stroke centers of 70 hospitals was higher, and the difference was significant( P<0.01). There were seven common problems in the construction of stroke centers in 175 hospitals, including insufficient attention paid by hospitals, lack of effective performance incentive policies, imperfect treatment procedures and medical norms, and so on. Conclusions:Experts on-site guidance plays an important role in the construction of stroke centers in China. At present, there were still problems to tackle in the construction of stroke centers in hospitals. In order to promote the standardized construction of stroke centers in China and improve the efficiency of stroke treatment, the authors suggest fuorther strengthening the importance attached by hospital leadership and the coordination and organization of functional departments, establishing stroke center models conforming to the actual situation of the hospital, seting up the post of brain and heart health manager, and improving the regional prevention and treatment level of acute stroke.
RESUMO
Phycocyanin is an important light-harvesting pigment antenna protein in cyanobacteria, rhodophyta, cryptophyta, and glaucophyta, with a variety of bioactivities. The introduction of purification and bioactivities of phycocyanin contributes to a significant improvement in developing it into final processed products. In fact, the knowledge of phycocyanin has experienced a rapid increase in the past 20 years, and has promoted the relevant technological revolution with a decisive contribution to final application. The purpose of this review is to critically introduce the present knowledge of purification and bioactivities of phycocyanin, and to illustrate main problems and prospects.
