Due to the coronavirus disease 2019 pandemic, the traditional outpatient and medical center pulmonary rehabilitation models for chronic obstructive pulmonary disease have been limited, while pulmonary rehabilitation technology has always been the focus of clinical and scientific research in rehabilitation. This article reviews the application status of remote pulmonary rehabilitation for chronic obstructive pulmonary disease under the coronavirus disease 2019 epidemic in recent years. From the selection and method of remote pulmonary rehabilitation equipment before the epidemic, to the development of rehabilitation forms and equipment innovation after the epidemic, the current status and problems of remote pulmonary rehabilitation are clarified. Establishing a remote pulmonary rehabilitation model in line with China’s national conditions is the direction and goal of future development.
Objective To investigate the preventive effect of simvastatin，a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor，on hypoxic pulmonary hypertension and the relation between it and the angiotensin Ⅱ receptor-1（AT1R） expression in pulmonary arteriole.Methods Thirty male Sprague-Drawley rats were randomly allocated into three groups：a control group，a hypoxic group and a simvastatin preventive group.The animal model of hypoxic pulmonary hypertension was established by exposing the rats to normobaric hypoxic condition（8 h×6 d×3 w），and the preventive group were treated with simvastatin 10 mg/kg before hypoxic processing while the control and hypoxic groups were treated with sodium chloride.The mean pulmonary pressure（mPAP），serum cholesterol concentration，right ventricular hypertrophy index [RV/（LV+S）]，percentage of the wall thickness in the external diameter（WT%），percentage of the wall area in the total vascular area（WA%），and the AT1R expression in pulmonary arterioles were measured.Results When compared with the hypoxic group，in the preventive group，the mPAP and RV/（LV+S）obviously reduced [（22.6±3.86）mm Hg vs （29.3±2.27）mm Hg，（25.13±0.75）% vs （33.18±1.58）%，Plt;0.01 respectively]，the indices of wall thickness of rat pulmonary arteriole and area also decreased significantly [WT%：（15.98±1.96）% vs （25.14±1.85）%；WA%：（54.60±3.94）% vs 74.77±4.52）%；Plt;0.01 respectively]，and the positive degree of AT1R still lessened noticeably（1.23±0.09 vs 1.57±0.13，Plt;0.01）.All of the indices above in the hypoxic group increased markedly compared with the control group（Plt;0.01 respectively）.However，the differences of serum cholesterol among three groups were not significant（Pgt;0.05）.Conclusions Simvastatin can suppress the expression of AT1R in pulmonary vessel and prevent hypoxic pulmonary hypertension.
ObjectiveTo construct the general practice tutors’ ability system in community training bases under the background of hospital-community integrated teaching of general practice.Methods From January to April 2021, literature analysis, expert group consultation, in-depth interview and questionnaire survey were conducted to construct the grass-roots general practice tutors’ ability system, and exploratory factor analysis method was applied, using main component analysis to extract the competency elements. Results There were 4 first level indicators and 20 second level indicators in the system, among which the first level indicators were personal characteristics and professionalism, teaching and research ability, basic level clinical practice ability, and base organization management ability. Conclusion This research enriches the indicators and connotations of the general practice tutors in community training base of general practice, and provides empirical research basis for the selection, ability training and performance evaluation of tutors in community practice bases of general practice medicine.
Objective To investigate pre-hypertension in aspects of its incidence, accompanied cardiovascular risk factors, and difference between urban and rural areas in Chengdu. Methods By cluster random sampling method, a total of 2 011 patients aged 35-70 years from urban and rural communities in Chengdu were selected as respondents. The investigation was conducted through questionnaire, physical examination and laboratory tests, so as to find out the main cardiovascular risk factors of pre-hypertension. All data were dual input into computer by a specially-assigned person. SPSS 13.0 software was used for analysis, Chi-square test was adopted for categorical data, and Plt;0.05 was taken as an index for significant difference. Results a) The incidence rate of pre-hypertensive in Chengdu was 33.6%, and it was 45.67% and 46.31% in urban and rural areas, respectively. In rural area, more male (51.04%) were affected than female (42.83%). b) The smoking population with pre-hypertension were mainly the male, and the ratio of rural male was 60% (132/220), far higher than that of urban male which was 32.6% (59/181). c) The pre-hypertensive population accompanied with diabetes was higher in urban (27.97%) than rural (14.01%). d) The pre-hypertensive population accompanied with hypercholesterolemia or low HDL was 33.04% (150/454) in urban, as twice as that in rural which was 16.41% (76/471). e) The pre-hypertensive population accompanied with abdominal obesity was far higher in urban (28.41%) than rural (12.74%). Conclusion Smoking is the risk factor which needs to be primarily intervened for male hypertensive patients in rural area. Impaired glucose tolerance is the common risk factor for both urban and rural residents, and hyperlipidemia is the most primarily risk factor for urban pre-hypertensive patients, followed by diabetes, and abdominal obesity.
Chronic obstructive pulmonary disease is often accompanied by anxiety or depression. The exacerbation of anxiety and depression can lead to the deterioration of chronic obstructive pulmonary disease, reduce patients’ quality of life, worsen poor prognosis, and increase the risk of death. Anxiety and depression are one of the important causes of death in patients with chronic obstructive pulmonary disease, but the complexity of their risk factors and pathogenesis often lead to clinicians being unable to make accurate diagnosis and treatment in a timely manner. Based on existing research, this article elaborates on the risk factors and pathogenesis of chronic obstructive pulmonary disease complicated with anxiety or depression, aiming to improve the diagnosis and treatment ability of clinical physicians for chronic obstructive pulmonary disease complicated with anxiety or depression, achieve timely diagnosis and treatment, improve patients’ prognosis, and improve quality of life.
