Study on predictive models for swallowing risk in patients with AECOPD.

BACKGROUND: Dysphagia is considered a complication in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). However, AECOPD may have risk factors for dysphagia. METHODS: Through a cross-sectional study, which included 100 patients with AECOPD. General information, Pulmonary function, COPD assessment test (CAT) and modified Medical Research Council (mMRC) were collected by questionnaire. The questionnaires were administered by uniform-trained investigators using standard and neutral language, and swallowing risk was assessed by using a water swallow test (WST) on the day of patient admission. RESULTS: Among the 100 included patients, 50(50%) were at risk of swallowing. Multivariate analysis using logistic regression analysis showed that age ≥ 74 years old, mMRC ≥ level 2, hospitalization days ≥ 7 days and the use of BIPAP assisted ventilation were important influencing factors for swallowing risk in patients with AECOPD. CONCLUSION: Patients with AECOPD are at risk for dysphagia, assessing age, mMRC, hospitalization days and the use of BIPAP assisted ventilation can be used to screen for swallowing risk, thus contributing to the implementation of early prevention measures.

[Analysis of animal models of stable chronic obstructive pulmonary disease based on clinical features of traditional Chinese medicine and western medicine].

This study analyzed the advantages and disadvantages of existing animal models in China and abroad and their goodness of fit based on the clinical characteristics and diagnostic criteria of stable chronic obstructive pulmonary disease(COPD) in traditional Chinese medicine(TCM) and western medicine, followed by the collation and summarization of model evaluation methodologies. The results showed that the existing animal models of stable COPD were mainly modeled via smoke exposure or the combination of multiple methods like smoke exposure plus lipopolysaccharide or protease or bacterial infection. These animal models generally failed to simulate the clinical characteristics of TCM, and their goodness of fit in western medicine was higher than that in TCM. There is a lack of research on the animal models of stable COPD and the disease-syndrome combination models. Although the modeling is guided by the pathogenesis or mechanism of diseased humans, the established models were still not identical with the actual clinical situations. In-depth research is needed to develop quantitative standards for stable COPD models.

Safety and efficacy of acupuncture for the treatment of chronic obstructive pulmonary disease: A systematic review protocol.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease with increasing morbidity and mortality that cause huge social and economic loss. Although recommended by guidelines, pulmonary rehabilitation has not been widely applied in clinics because of its inherent limitations. Acupuncture therapy (AT) as one of the most popular treatments in traditional Chinese medicine has been used to treat COPD. We aim to evaluate the safety and efficacy of acupuncture in the treatment of COPD. METHODS: Web of science, PubMed, Springer, Medline, Cochrane Library, EBASE, WHO International Clinical Trials Registry Platform (ICTRP), China National Knowledge Infrastructure Database (CNKI), Wan Fang Database, Chinese Scientific Journal Database (VIP), and Chinese Biomedical Literature Database will be searched from their inception to May 10, 2019. Randomized controlled trials that evaluated the safety and efficacy of acupuncture for the treatment on patients with COPD will be included. The primary outcome measures will include Dyspnea scores, lung function and blood eosinophils. The secondary outcome measures will include St George's Respiratory Questionnaire and 6-minute walk distance. Study selection, data extraction, and risk of bias assessment will be independently undertaken, respectively. Statistical analysis will be conducted by RevMan software (version 5.3). RESULTS: This study will provide high-quality synthesis based on current evidence of acupuncture treatment for COPD in several aspects, including symptom score, quality of life score, side effects and laboratory examination, such as lung function text, blood eosinophils (EOS) etc. CONCLUSION:: The results of this study will provide updated evidence for weather acupuncture is an effective and safe intervention for COPD. ETHICS AND DISSEMINATION: It is not necessary for this systematic review to acquire an ethical approval. This review will be disseminated in a peer-reviewed journal or conference presentation.

Efficacy and safety of Chinese medicines for asthma: A systematic review protocol.

BACKGROUND: Asthma is a complex disease associated with many factors such as immunologic, environmental, genetic, and other factors. Common medicines used to treat asthma include ß-agonist and glucocorticoid. However, in the long-term treatment, the effect of the above-mentioned drugs is not satisfactory, so many patients choose oral Chinese medicines instead of western medicines. The introduction of Chinese medicines therapies, a rapid proliferation of the literature on management of asthma in general, call for novel ways of evidence synthesis in this area. This systematic review is to systematically summarize and evaluate a large number of evidences for Chinese herbal interventions for asthma. Evaluate the efficacy and safety of Chinese medicines in the treatment of asthma and inform a decision aid for the clinical encounter between patients and clinicians. In addition, it helps to establish a future research agenda. METHODS: Five English databases (PubMed, Web of science, EBASE, Springer Cochrane Library, and WHO International Clinical Trials Registry Platform) and 4 Chinese databases (Wanfang Database, Chinese Scientific Journal Database, China National Knowledge Infrastructure Database, and Chinese Biomedical Literature Database) will be searched normatively according to the rule of each database from the inception to the present. The literature screening, data extraction, and quality assessment will be conducted by 2 researchers independently. Data will be synthesized by either the fixed-effects or random-effects model according to a heterogeneity test. Asthma control test symptom score will be assessed as the primary outcome. The curative effect of single symptom and sign; Withdrawal and reduction of western medicines in a course of treatment, including: time, type, and quantity; Maintenance of western medicines after the course of treatment, including: type, quantity; Asthma Quality of Life Questionnaire; laboratory efficacy indexes as the secondary outcome. General physical examination; routine examination of blood, urine, and stool; electrocardiogram; liver and kidney function examination; possible adverse reactions and related detection indicators as the security indexes. Meta-analysis will be performed using RevMan5.3.5 software provided by the Cochrane Collaboration. RESULTS: This study will provide high-quality synthesis based on current evidence of Chinese medicines treatment for asthma in several aspects, including asthma control score, side effects and laboratory examination such as lung-function test, serum total immunoglobulin, and so on. CONCLUSION: The results of this study will provide updated evidence for whether Chinese medicines is an effective and safe intervention for asthma.

Tai Chi for the treatment of chronic obstructive pulmonary disease: A systematic review protocol.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease with increasing morbidity and mortality that cause huge social and economic loss. Although recommended by guidelines, pulmonary rehabilitation has not been widely applied in clinics because of its inherent limitations. Free from restrictions of specific training venues and equipment, Tai Chi, as a kind of pulmonary rehabilitation, has been used to cure the COPD, yet the efficacy and safety of Tai Chi remains to be assessed. In this study, we aim to draw up a protocol for systematic review to evaluate the efficacy and safety of Tai Chi for COPD. METHODS: We will search the following electronic databases from inception to December 31, 2018: PubMed, Web of Science, Medline, Cochrane Central Register of Controlled Trials, Springer, EMBASE, the China National Knowledge Infrastructure Database, Wan Fang Database, the Chinese Scientific Journal Database, and Chinese Biomedical Literature Database. Clinical trial registrations, potential gray literatures, relevant conference abstracts and reference list of identified studies will also be searched. The literature selection, data extraction, and quality assessment will be completed by 2 independent authors. Either the fixed-effects or random-effects model will be used for data synthesis based on the heterogeneity test. Changes in lung function will be evaluated as the primary outcome. Symptom assessment, quality of life (SGRQ), medication usage, exacerbations, and adverse events will be assessed as the secondary outcomes. The RevMan V.5.3.5 will be used for Meta-analysis. RESULTS: This study will provide a synthesis of current evidence of Tai Chi for COPD from several aspects, such as lung function, SGRQ, medication usage, exacerbations, and adverse events. CONCLUSION: The conclusion of our study will provide updated evidence to judge whether Tai Chi is an effective solution to COPD patients. PROSPERO REGISTRATION NUMBER: PROSPERO CRD42019122791.

Acupuncture for the treatment of allergic rhinitis: A systematic review protocol.

BACKGROUND: Allergic rhinitis is a major chronic inflammatory disease of the respiratory tract. A large number of epidemiological investigations have shown that the prevalence of allergic rhinitis (AR) is increasing, resulting in a large burden of disease. Desensitizing drugs such as nasal glucocorticoids and antihistamines are commonly used to treat allergic rhinitis, but this method has a long treatment period and is prone to repeated attacks, and there are certain adverse reactions. Acupuncture can be used to treat a wide variety of diseases including allergic rhinitis without the occurrence of drug damage. We aim to evaluate the efficacy and safety of acupuncture in the treatment of allergic rhinitis. METHODS: Relevant databases include the English databases incorporating Web of science, PubMed, Springer, Medline, Cochrane Library, EBASE, WHO International Clinical Trials Registry Platform (ICTRP), as well as the Chinese databases like the China National Knowledge Infrastructure Database (CNKI), Chinese Scientific Journal Database (VIP), Wanfang Database, and Chinese Biomedical Literature Database will be searched normatively according to the rule of each database from the inception to September 1, 2018. Reference list of identified studies, potential gray literatures, relevant conference abstracts, and clinical trial registrations will also be searched. The literature screening, data extraction, and quality assessment will be conducted by 2 researchers independently. Data will be synthesized by either the fixed-effects or random-effects model according to a heterogeneity test. Symptom score will be assessed as the primary outcome. Rhinoconjunctivitis quality of life questionnaire (RQLQ), participants with asthma can use asthma control test (ACT), medicine usage and scoring, laboratory examination, and side effects or adverse events will be evaluated as the secondary outcome. Meta-analysis will be performed using RevMan5.3.5 software provided by the Cochrane Collaboration. RESULTS: This study will provide high-quality synthesis based on current evidence of acupuncture treatment for allergic rhinitis in several aspects, including symptom score, drug score, quality of life score, asthma control score, side effects and laboratory examination such as nasal function test, serum total immunoglobulin (IgE), nasal secretion smear, etc. CONCLUSION:: The results of this study will provide updated evidence for weather acupuncture is an effective and safe intervention for allergic rhinitis. ETHICS AND DISSEMINATION: It is not necessary for this systematic review to acquire an ethical approval. This review will be disseminated in a peer-reviewed journal or conference presentation.
