Objective:To understand the coronavirus disease 2019(COVID-19)prevention and control work and the problems and difficulties faced by non-government primary medical institutions in China during the epidemic period.Methods:A survey on the coronavirus disease 2019(COVID-19)prevention and control work of non-government primary medical institutions was conducted on April 14 to 21, 2020 with the self-designed questionnaire. The questionnaire contained three parts: the first part was basic information of medical staff in non-government primary medical institutions, including position and institutional information; the second part was the status quo of non-government primary medical institutions participating in the prevention and control of COVID-19, including the specific work and difficulties faced by the responders during the epidemic period; and the third part was the prevention and control effect of COVID-19 in the responders′ institutions, including whether there were confirmed cases and infected medical staff. An online invitation was issued among the members of General Practice Branch of Chinese Non-government Medical Institution Association. The invited participants included the heads, general practitioners and other medical personnel of the non-government primary medical institutions the invited participants voluntarily scanned the online two-dimensional code to fill in.Results:A total of 761 individuals in primary health institutions from 20 provinces, municipalities and autonomous regions in China participated in the survey. There were 290 (38.1%) men and 471 (61.9%) women with age of 40(32, 48) years; 83.0% (632/761) had worked for more than 5 years; 33.8% (257/761) owned primary professional titles and 33.0% (251/761) owned intermediate titles. Among all participants 28.5% (217/761) were general practitioners, 26.9% (205/761) were institutions/department managers, 14.6% (111/761) were specialists and 40.3% (307/761) were other related personnel. A total of 549 institutions continued to operate during the epidemic period and 96.5% (530/549) participated in the work related to the prevention and control of the epidemic, including prescreening and triage, health consultation, follow-up of suspected patients, donation, quarantine of suspected cases, follow-up of close contacts/discharged patients, diagnosis and treatment of patients with new coronavirus pneumonia. 44.7% (340/761) of respondents participated in the epidemic prevention as front-line staff and directly contacted patients/suspected patients, and 63.1% (480/761) participated in the epidemic prevention work of primary medical institutions, including clinical outpatient service, prescreening triage and screening. The working sites were not limited to the institutions, but also other sites including high-speed railway station. The 97.8% (744/761) responders expressed their willingness to participate in epidemic prevention work under the unified leadership and command of the state. The 63.9% (486/761) of the responders were worried about the lack of protective equipments and measures, and 90.4% (688/761) respondents showed that they needed medical supplies (protective equipment: masks, goggles, protective gowns, etc.).Conclusion:The participation of non-government primary medical institutions and their staff in COVID-19 infection prevention and control is a key component of the epidemic prevention process.

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.

Objective To observe the clinical curative effect of enteral nutrition (EN) liquid rich in omega-3 polyunsaturated fatty acids (ω-3PUFA) for patients suffering from acute respiratory distress syndrome (ARDS) and treated with mechanical ventilation.Methods A prospective study was conducted, 40 patients with ARDS admitted and treated in the intensive care unit (ICU) and respiratory department in the Traditional Chinese Medicine Hospital of Huzhou from May 2007 to October 2016 were enrolled, and they were randomly divided into a study group and a control group, each group 20 cases. The same heat EN support of different prescriptions was given respectively in the two groups, nasal feeding with EN emulsion rich in ω-3PUFA (TPF-T) was applied in the study group, while in the control group, nasal feeding with EN suspension liquid of protein fiber type (TPF) was given, and the target energy established for the two groups was 104.0 - 125.5 kJ·kg-1·d-1. In the two groups, before and after treatment for 7 days, the changes of nutrition indexes [total protein (TP), albumin (ALB)], inflammatory index [C-reactive protein (CRP)], immune indexes (T cell subgroup CD4, CD8 and CD4/CD8), blood gas analysis indexes [arterial blood oxygen partial pressure (PaO2), oxygenation index (PaO2/FiO2)] and mechanical ventilation time, the length of stay in ICU and fatality rate were observed; the occurrences of false aspiration, feeding tube obstruction, high blood sugar, excessive water, diarrhea, constipation, etc. complications related to the process of the treatment were observed in the two groups. Results After treatment, the levels of TP, ALB, CD4, CD4/CD8, PaO2, PaO2/FiO2 in two groups were higher than those before treatment, the levels of CRP and CD8 were lower than those before treatment, and the improvement degrees of indexes in study group were superior to those in the control group [TP (g/L): 59.9±4.8 vs. 58.6±4.1, ALB (g/L): 31.9±3.4 vs. 31.1±4.4, CRP (mg/L): 25.8±18.5 vs. 38.1±24.9, CD4: 0.30±0.05 vs. 0.28±0.04, CD8: 0.21±0.03 vs. 0.19±0.04, CD4/CD8: 1.57±0.39 vs. 1.55±0.42, PaO2 (mmHg, 1 mmHg = 0.133 kPa): 152.7±15.8 vs. 140.6±22.2, PaO2/FiO2 (mmHg): 304.5±32.1 vs. 280.2±44.1]; the survival patient mechanical ventilation time (days: 7.1±2.2 vs. 9.2±3.5) and length of stay in ICU (days: 10.4±2.8 vs. 12.6±3.6) were significantly shorter in study group than those in control group (allP < 0.05), and fatality rate was 15.0%in both groups.Conclusion The EN liquid rich in ω-3PUFA is more beneficial to the recovery of respiratory function than EN of protein fiber type in patients with ARDS, and the former EN also can shorten the mechanical ventilation time and the length of stay in ICU.

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.

Objective To discuss the relationships between qi-arrival and mind-control, qi-arrival and qi-regulation, and to define qi-arrival by tracing the relevant records in Nei Jing (Classic of Internal Medicine) and Nan Jing (Classic of Difficult Issues). Method Thirty-seven relevant ancient books of the two classics were reviewed and the notes by WANG Bing, MA Shi, and YANG Shang-shan were referred. Result Mind-control requires the spirits of the practitioner, patient and environment, as well as observing and waiting for the arrival of qi. Regarding qi-regulation, theories involve that qi-arrival achieves same reinforcing and reducing effect as qi-regulation, qi-regulation is elucidated from the correct location of acupoint, proper needling depth and direction, and to regulate qi by observing the arrival of qi. Besides, the changes of internal and external environments also influence qi-arrival via qi-regulation and mind-control. Conclusion Qi-arrival is closely related to mind-control and qi-regulation in obtaining, differentiation, and adjustment. Mind-control and qi-regulation assist each other through the whole acupuncture process, which is the core of qi-arrival.

Objective:To investigate the status quo of the management of chronic obstructive pulmonary disease (COPD) in primary care health institutions in Miyun District of Beijing.Methods:The Measures to Improve Medical Services in Primary Medical and Health Institutions was issued by Beijing Municipal Health Commission in June 2019. In August 2020, a survey on COPD management status after the measures was conducted with self-designed questionnaire among 19 community health service centers and 61 general practitioners (GPs) from 4 centers in Miyun District of Beijing. Two questionnaires were used for the survey: one was on the status of medical institutions (institution questionnaire, filled by the person in charge of the center) and other was on COPD knowledge of general practitioners (doctor questionnaire, filled by selected GPs). Results:For health institution, 19 valid questionnaires were collected. Among them, 12 centers were equipped with lung function examination equipment after reform; 17 centers were equipped with inhaled corticosteroids/long acting β 2 receptor agonists (ICS/LABA); 12 centers carried out the contract management of family doctors for COPD; 267 patients signed the contract, 7 centers followed up the signed patients at least twice a year; 13 centers referred patients to Miyun District Hospital with 2 024 referrals per year. For GPs, 61 valid questionnaire were collected with a recovery rate of 100% (61/61). Among them 12 GPs (20%) had contracted management for COPD patients; 12 GPs (20%) had referred COPD patients to the secondary or tertiary hospitals; and 9/12 of GPs referred the patients for lung function examination due to the needs of diagnosis or follow-up.The mean COPD-related knowledge score was (58.9±20.0), compared with the score of 65 GPs from the 4 same community centers tested in 2018 (63.2±18.9), there was no significant difference ( t=0.456, P>0.05). Conclusions:The implementation of the primary care institution measures in Beijing promoted the management of COPD and improved capacity building in primary health institutions, also promoted the work docking between primary health institutions and secondary, tertiary hospitals. However, it is still necessary to strengthen the ability training of general practitioners in relevant knowledge and skills to improve their management ability of COPD.
