ABSTRACT
Objective:To explore the effect of case management of chronic obstructive pulmonary disease (COPD) in the nurse-led clinics.Methods:A total of 50 patients with COPD who met the selection criteria in the outpatient department of the respiratory department of Shantou Central Hospital were enrolled from March 2019 to March 2020. Case management was carried out by specialist nurses in the outpatient department. Body Mass Index (BMI), the forced expiratory volume in one second/predicted value ratio (FEV 1%pred), modified British medical research council (mMRC), 6-min walking distance (6MWD), COPD assessment test (CAT), and St.George Respiratory Questionnaire (SGRQ), basic activities of daily living (BADL) were compared before and after 6 months′ case management. The difference of medication compliance after case management was also analyzed. Results:There were statistically significant differences in the mMRC[(1.9±1.2) vs (1.4±1.1) points], 6MWD[(238.1±84.9) vs (284.1±113.8) m] and CAT scores [(19.7±6.6) vs (17.1±5.9) points], which suggested the improvement of dyspnea, self-conscious symptoms and exercise performance in these patients (all P<0.05). The BADL scores [(87.8±5.4) vs (90.00±7.5) points] and the total score of SGRQ [(48.0±7.3) vs (45.0±6.9) points] were significantly different (both P<0.01). These indicators were improved after the implementation of case management. Patients were followed up for 1 month, 3 months and 6 months, and the improvement of medication compliance score was statistically significant [(7.1±0.8) vs (7.4±0.8) vs (7.7±0.5) points] ( P<0.01). Conclusion:The implementation of respiratory nursing clinic can effectively manage COPD patients, improve medication compliance of patients, so as to improve the degree of dyspnea, self-conscious symptoms, self-care ability and exercise endurance of patients.
ABSTRACT
With the development of computer network technology,network teaching has become an important mode of continuing medical education.There are many kinds of medical imaging websites from both domestic and foreign.In general,they can be divided into three main categories,in terms of society official websites,academic journal websites,and educational resource websites.On the basis of the introduction of the representative domestic and international medical imaging websites,this paper analyzes the advantages and disadvantages of them,and emphasizes some measures to improve the application value of them in continuing medical education,including to establish an authoritative academic website to achieve continuing medical education credits,to strengthen the resources and function of various medical image sites,and to promote intelligent and personalized self-learning,etc.We hope the combination of medical imaging websites with continuing medical education will be much closer,so as to provide a good platform for imaging personnel to improve their professional level and scientific research ability.
ABSTRACT
This paper introduced the current situation of WeChat's official accounts of medical imaging.According to the operation agents,they can be divided into different categories,including professional societies,hospitals and departments,medical companies,academic journals,medical imaging websites and personal accounts.This paper also analyzed the advantages and disadvantages of WeChat's official accounts of medical imaging.Some measures were proposed to improve their application value in continue medical education (CME),such as establishing a platform of WeChat's official account with high approval and authority to award CME credit,integrating various kinds of network resources,strengthening the abundance,systematicness,chronergy and practicality of the resources,setting up and improving the evaluation mechanism of CME credit award,so as to provide a CME platform for the staff of medical imaging.
ABSTRACT
Picture archiving and communication system ( PACS ) based on digital teaching platform of medical imaging consists of web teaching system and teaching resource library of medical imaging.The web teaching system includes four function modules of classroom management,work management,teaching management and test management.The teaching resource library includes script,pictures,and audio,video and animation materials of theoretical books,typical cases,examination techniques and medical imaging equipments.Utilized in theoretical and practical classes,the teaching characteristic of medical imaging is made prominent,and the subjective motility of the students is brought into play.
ABSTRACT
[Objective]To investigate the protective effect of Tanshinone IIA (TSⅡA) against interleukin-1β (IL-1β) induced obstruction of energy metabolism of rabbit annulus fibrosus cell in vitro.[Methods]Rabbit annulus fibrosus (AF) cells were cultured in 3-dimension alginate beads and randomly divided into 7 groups. Various concentrations of TSⅡA and IL-1β was added to the medium for intervention: no drug was added in group A as normal control, 4 μg/ml TSⅡA in group B, 10 μg/ml IL-1β in group C, and both 10 μg/ml IL-1β and different concentrations of TSⅡA in groups D-G (0.5 μg/ml, 1 μg/ml, 2 μg/ml and 4 μg/ml respectively). After 3 days of incubation, the cells were collected for measuring the activity of Na+-K+-ATPase and succinate dehydrogenase (SDH), MTT assay for cell proliferation, and AnnexinⅤ-PI staining for cell apoptosis.[Results]The activity of Na+-K+-ATPase of group G (10 μg/ml IL-1β+4μg/ml TS IIA; 3.23±0.28 U/mgprot) was increased significantly as compared with group C (10 μg/ml IL-1β; 1.118±0.15 U/mgprot, P＜0.01). The activity of SDH of group G was 12.48±0.97 U/mgprot, which was obviously higher than that of group C (3.03±0.60 U/mgprot, P＜0.01). The absorbance of MTT assay of group G (0.77±0.06) was significantly increased as compared with group C (0.31±0.07,P＜0.01). The absorbance of groups D-G increased as the concentration of TSⅡA increased. The apoptotic cell rate and dead cell rate of group G was 21.08±1.46% and 8.99±0.33%, which were both lower than that of group C (43.11±2.7,P＜0.01 and 11.71±0.32,P＜0.01).[Conclusion]TSⅡA is able to promote cell proliferation and decrease cell apoptosis of AF by alleviating IL-1β induced inhibition on cell energy metabolism.
ABSTRACT
Objective To explore the clinical value of radiological equipment for injury treatment in earthquake. Methods s One hundred and forty-three cases of the injury in earthquake using radiological equipment were analyzed retrospectively. Resultss All of the cases were performed X-ray plain film examination, CT in 78 cases and MRI in 19 cases. Imaging examination could establish definitive diagnosis in 143 cases of the injury in earthquake. Conclusion Radiological equipment is the most valuable examination equipment in diagnosis of the injury in earthquake.
