RESUMO

ObjectiveBased on the experience of traditional quality evaluation, the quality of Atractylodis Macrocephalae Rhizoma(AMR) with different production methods such as direct seeding, transplanting after seedling raising, topping and non-topping, and difference in growth years was compared. MethodVernier caliper was used to measure the trait data of AMR in different production methods. Paraffin sections of AMR with different production methods were made by saffron solid green staining, and the microstructure was observed. The contents of water-soluble and alcohol-soluble extracts in AMR with different production methods were determined according to the 2020 edition of Chinese Pharmacopoeia. The content of water-soluble total polysaccharides in AMR with different production methods was detected by sulfuric acid-anthrone method. Fiber analyzer was used to detect the content of fiber components in AMR with different production methods. The contents of monosaccharides, oligosaccharides and some secondary metabolites in AMR with different production methods were detected by ultra performance liquid chromatography(UPLC), and the differences of chemical components were compared by multivariate statistical analysis methods such as principal component analysis(PCA) and partial least squares-discriminant analysis(PLS-DA). ResultIn terms of traits, the 3-year-old AMR with direct seeding and without topping was close to the high-quality AMR with "phoenix-head and crane-neck, strong sweetness and clear aroma" recorded in ancient materia medica, followed by the 3-year-old AMR with topping after transplanting, while the 2-year-old AMR with topping after transplanting with high market circulation rate was generally fat and strong with mild odor. In the microscopic aspect, the arrangement of xylem vessels and fiber bundles in the 3-year-old samples formed two obvious rings. Compared with the 2-year-old samples cultivated in Bozhou and Zhejiang, the 3-year-old samples without topping after transplanting had more wood fibers. In terms of chemical composition, the contents of 70% ethanol extract, fructose, glucose, sucrose, 1-kestose, atractylenolide Ⅰ, chlorogenic acid, neochlorogenic acid, cryptochlorogenic acid and other components in 3-year-old AMR with direct seeding and without topping were significantly higher than those in the other three samples(P<0.05). The contents of cellulose, 70% ethanol extract, sucrose, atractylenolide Ⅰ, atractylone and other components in 3-year-old AMR with topping after transplanting were significantly higher than those in the 2-year-old AMR with high market circulation rate(P<0.05), while the contents of water-soluble extract and water-soluble total polysaccharides in 2-year-old samples with topping after transplanting were significantly higher than those in the 3-year-old AMR with topping after transplanting, direct seeding and without topping(P<0.05). ConclusionUnder the current mainstream production mode, too much manual intervention makes AMR heavily enriched in polysaccharides and increased the yield, but the accumulation of sweet substances, fragrant substances and fiber substances is insufficient, which affects its quality. The current quality standard of AMR has some shortcomings in guiding the high quality production of it, it is suggested to revise the quality standard of AMR, supplement the quantitative analysis of secondary metabolites, and strengthen the production of imitation wild AMR.

RESUMO

By reviewing the research history on quality comparison between wild and cultivated Chinese crude drugs, this paper systematically combed the relevant research reports since the 1950s, and summarized and analyzed the results of existing comparative studies, and found that the existing comparative research on the quality of wild and cultivated Chinese crude drugs were mainly focused on several aspects, including characteristics, microstructures, chemical compositions, pharmacodynamic effects, and genetic diversity. Among these, comparative studies of chemical compositions have been the dominant approach, with a particular emphasis on comparing the contents of index components. However, research on pharmacodynamic effects remained relatively limited. Due to various factors such as sample quantity, sample origin, growth period and cultivation methods, the differences in quality between wild and cultivated Chinese crude drugs vary significantly. In general, most wild Chinese crude drugs exhibited higher quality than cultivated products, with significant differences in their characteristics. The contents and proportions of some chemical components underwent noticeable changes, particularly with a marked increase in the proportion of primary metabolites after cultivation. The quality of cultivated Chinese crude drugs is closely related to the cultivation practices employed. Chinese crude drugs produced through wild nurturing, simulated wild planting, ecological cultivation, and other similar methods demonstrate quality levels comparable to those of wild Chinese crude drugs. Based on the analysis results, it is recommended to explicitly specify the cultivation practices and cultivation period of cultivated Chinese crude drugs in comparative studies of the quality between wild and cultivated Chinese crude drugs. Multiple technical approaches, including characteristics, microscopy, non-targeted metabolomics combined with quantitative analysis of differential components, and bioefficacy evaluation, should be employed to comprehensively assess the quality disparities between wild and cultivated Chinese crude drugs. Moreover, research efforts should be intensified to investigate the changes in pharmacodynamic effects resulting from differences in plant cell wall composition, primary metabolites, and secondary metabolites, in order to guide the production of high-quality Chinese crude drugs.

RESUMO

Objective:To investigate the status quo of nursing capacity for chronic respiratory disease in community health service centers.Methods:A questionnaire survey on nursing capacity for chronic respiratory disease was conducted in November 2018 among nurses working in internal medicine, general practice and chronic disease management departments of 4 community health service centers in Beijing Miyun District. The questionnaire included the knowledge and work content of chronic respiratory diseases. At the same time semi-structured interviews was conducted on the role of nurses in the management of chronic respiratory diseases among nurses selected by purposive sampling method.Results:In the study 63 valid questionnaires were collected and 14 nurses were interviewed. The results showed that the total score of nurses′ knowledge about chronic respiratory diseases was (62.0±14.4), and the scores of knowledge of chronic obstructive pulmonary disease (COPD), bronchial asthma and obstructive sleep apnea were (55.5±19.3), (61.0±21.6), (69.5±25.1), respectively. The total knowledge score of nurses with middle-rank professional title or above was higher than that of those with primary title [(67.0±12.9) vs. (54.0±13.6), t=-3.07, P<0.01]. The work contents mainly involved were nursing procedures(22/63,34.9%), health education(18/63,28.6%) and nursing evaluation(8/63,12.7%).Three themes were extracted from the deep interviews: the main work contents for nurses should be nursing procedures, nurses should participate in the chronic respiratory disease management as a member of the integrated medical team; nurses expected practice-oriented trainings of chronic respiratory disease management. Conclusions:The knowledge of chronic respiratory diseases among nurses in community health center needs to be improved, and the nursing skills special for respiratory diseases are needed. It is suggested to develop training courses and nursing guidelines suitable for community health centers and for nurses to participate in chronic respiratory disease management as team members, so that nurses in primary care institutions can play a better role in the management of chronic respiratory diseases.

RESUMO

Objective:To analyze the status of prevention and control of COVID-19 in primary care institutions at the early stage of the epidemic.Methods:Thirty healthcare professionals from various places of China were recruited in the study from 6 thto 16 th February 2020 through WeChat platform advertising and by purposive sampling method. They were general practitioners (GPs), administrators, and other specialists, all of whom were involved in the prevention and control of COVID-19. Personal interview and focus group discussion were conducted online. The topic guide was as follows: (1) Introduction of the work that primary healthcare professionals carried out during the outbreak of COVID-19. (2) Difficulties and challenges that healthcare professionals encountered. (3) Opinions on the prevention and control of COVID-19. (4) Advices on future outbreak of similar epidemics or disease. NVivo 12 software system was used to code and classify the interview content, and thematic framework analysis was used to sort out and analyze the data and extract the interview themes. Results:Six themes were extracted: (1) The community hospital leaders led the work in time but job distribution and prevention procedures were insufficient; and the workload of GPs was heavy. (2) Primary care settings had carried out pre-screening and triage; while outpatient clinic continued to provide health care service for local residents, especially stressing online service and consultation to reduce the population mobility. (3) GPs should make full use of technical advantages and participate in joint prevention and control. (4) GPs offered various health education to residents to improve their awareness of self-protection. (5) GPs lacked professional skills and needed more related training, while the current training were still insufficient. (6) There were not enough supplies and GPs had increasing worries about the infection risks.Conclusions:GPs play an important role in effectively curbing the spread of the epidemic. It is suggested that the setting of triage and fever clinic in primary care institutions need to be readjusted; and the training of prevention and control knowledge and skill for GPs need to be strengthened in the future.

RESUMO

Objective:To investigate the current status of chronic respiratory disease (chronic obstructive pulmary disease, bronchial asthma and obstructive sleep apnea) management capacity in community health centers in Beijing Miyun district.Methods:From November 21 to 22,2018,nineteen community health centers and 65 general practitioners in Miyun district of Beijing were selected to participate in a questionnaire survey. The self-designed questionnaire was divided into two parts: the questionnaire for medical institutions(institution questionnaire)and questionnaire for general practitioners(doctor questionnaire). The institution questionnaires were distributed by the Miyun District Health Commission,and filled in by the person in charge of the institution; the knowledge questionnaires were sent to all general practitioners of 4 community health service centers. The two independent sample t test was used to compare the measurement data in accordance with normal distribution between the two groups, and analysis of variance was used for multi group comparison. Results:Nineteen institution questionnaires were sent to all centers in the district and all 19 valid questionnaires were recovered. Among them, 18 centers thought that chronic respiratory diseases should be included in the management of chronic non-communicable diseases, and health records should be established to achieve regular follow-up monitoring, but only one center had put asthma in the record. Nine centers purchased pulmonary function instrument; 8 centers were equipped with inhaled glucocorticoid, and 1 center was equipped with β 2-receptor agonists. The effective recovery rate of knowledge questionnaire was 100.0% (65/65). There was no significant difference in the knowledge scores of three kinds of chronic respiratory diseases (chronic obstructive pulmary disease, bronchial asthma, obstructive sleep apnea) among general practitioners [(63±19), (64±23), (62±21), F=0.087, P>0.05]. The scores of general practitioners with different ages and professional titles were (57±15), (66±13), (42±16) and (54±19), (67±12), (68±11) respectively. There were significant differences in the knowledge scores of general practitioners with different ages and professional titles ( F= 8.582 and 6.079, all P<0.05). The average scores of general practitioners with age>50 years or junior professional title were lower than others. Conclusions:The leaders of each center in Miyun district have a clear understanding of the necessity of diagnosis and treatment of chronic respiratory diseases, but there are still some problems, such as insufficient attention to chronic respiratory system, insufficient investment in disease management infrastructure, and lack of professional knowledge of chronic respiratory diseases among general practitioners. It is hoped that in the future, chronic respiratory diseases can be introduced into public health service projects, investment in related disease infrastructure will be strengthened, and comprehensive respiratory knowledge and ability training courses suitable for grass-roots general practitioners can be popularized as soon as possible.
