Observation on the Effect of Non-Invasive Ventilator Combined with Conventional Therapy in the Treatment of Chronic Obstructive Pulmonary Disease Complicated with Respiratory Failure

Objective:To explore the clinical effect of a non-invasive ventilator combined with conventional therapy in the treatment of patients with chronic obstructive pulmonary disease(COPD)combined with respiratory failure.Methods:68 patients with COPD combined with respiratory failure treated in our hospital from September 2021 to October 2023 were selected as the research subjects.Using the random number table method,they were divided into a control group and an experimental group of 34 cases each.The control group received conventional symptomatic treatment,and the experimental group received non-invasive ventilator treatment based on the control group.The clinical effects,blood gas indicators(partial pressure of carbon dioxide(PaCO_(2)),partial pressure of oxygen(PaO_(2)),arterial oxygen saturation(SaO_(2))),lung function(forced expiratory volume in 1 second(FEV1),forced vital capacity(FVC),6 min walking distance),complications,and inflammatory factor levels(c-reactive protein(CRP),interleukin-6(IL-6),neutrophil-to-lymphocyte ratio(NLR))of the two groups of patients were observed.Results:(1)The clinical efficacy of the patients in the experimental group(33/97.06%)was more significant as compared with the control group(25/73.53%)(P<0.05);(2)After treatment,the clinical efficacy of the two groups of patients in terms of FEV1,FEV1/FVC,6-minute walking distance,PaO_(2)and SaO_(2)all increased in the experimental group as compared to that of the control group(P<0.05);(3)After treatment,the PaCO_(2),CRP,IL-6,and NLR of the two groups of patients decreased,and the decrease in the experimental group was higher than that of the control group(P<0.05);(4)The patients’complication rate in the experimental group(2/5.88%)was lower as compared to that of the control group(9/26.46%)(P<0.05).Conclusion:Non-invasive ventilators combined with conventional therapy achieved good clinical results in treating patients with COPD and respiratory failure.

Meta-analysis of the acupoint application therapy for stable chronic obstructive pulmonary disease

Objective:To systematically evaluate the clinical efficacy and safety of acupoint application in the treatment of stable chronic obstructive pulmonary disease.Methods:A comprehensive search of domestic and international databases,the search time is limited to nearly ten years,collecting traditional Chinese medicine acupoint application in the treatment of chronic obstructive pulmonary disease in stable phase of randomized controlled trials.Literature screening,information extraction and literature quality evaluation were carried out independently by two researchers,and Meta analysis was carried out by Revman software.Results:A total of 42 RCTs with a total of 4192 patients were included.The results of Meta analysis showed that:Compared with the routine treatment of western medicine,the addition of acupoint application therapy can significantly increase the effective rate[RR=1.23,95%CI(1.19,1.27),P<0.00001]and FEV1/FVC[MD=4.46,95%CI(3.17,5.76),P<0.00001].Significantly improved BODE index[MD=-0.63,95%CI(-0.87,-0.40),P<0.00001],SGRQ score[MD=-6.77,95%CI(-9.81,-3.72),P<0.00001],CAT score[MD=-3.33,95%CI(-3.87,-2.79),P<0.00001]and TCM syndrome integral[MD=-3.51,95%CI(-3.96,-3.06),P<0.00001].The differences is statistically significant and the safety profile is good.Conclusion:On the basis of routine treatment of COPD western medicine,acupoint application therapy can significantly improve the clinical symptoms of patients with less adverse reactions.However,due to the limitations of the research,high-quality research is still needed to provide further evidence.

Dance Movement Therapy: A Promising Lifestyle Intervention in the Management of Chronic Obstructive Pulmonary Disease

Chronic Obstructive Pulmonary Disease(COPD),a progressive multicomponent malady with high morbidity and mortality,is an important public health challenge,throughout the world.Despite remarkable progress in its diagnostic and therapeutic modalities,significant number of patients,especially the elderly,continue to suffer from distressing dyspnoea and harrowing extra-pulmonary manifestations limiting their daily activities,with resultant exercise intolerance.Dance Movement Therapy(DMT),a pleasurable and feasible exercise,has been found to be equally efficacious when compared to routinely prescribed physical exercises.Moreover,it has aesthetic expression,attractive to both genders irrespective of age,tempting to those with disabilities,and a fruitful tool in developing self-confidence.During the current stressful situation,caused by COVID-19 pandemic,the COPD patients,notably those over 70 years,are particularly vulnerable to intensification of symptoms and some of them may experience serious disorders of mental illness.Home isolation,social distancing,limiting outdoor activities and prohibiting participation in group exercises,though being appropriate prophylactic measures,are likely to add to already existing physical inactivity and heighten stress and depression,with deleterious effects on overall well-being.Solo dancing,while restricted to home,is a highly accessible,doable,sustainable and well rewarding alternative.

Ambulatory Oxygen in Chronic Obstructive Pulmonary Disease

Ambulatory oxygen has been shown to improve pulmonary hemodynamics and reduce dynamic hyperinflation in patients with Chronic Obstructive Pulmonary Disease. Therefore, it is hypothesized to be of benefit in patients with either exertional desaturation or dyspnoea. There is evidence of short-term improvements in exercise distance, exercise time, breathlessness, oxygen saturation and minute ventilation. However, longer term studies only identified improvements in oxygenation and minute ventilation. The benefits were even more limited in patients with no resting hypoxemia. The role in improving exercise training in pulmonary rehabilitation by increasing exercise time and reducing dyspnoea was marginal and no improvements were detected in walking distance or quality of life. Practical considerations make compliance with ambulatory oxygen therapy a major issue with the weight of oxygen and social unacceptability the most often quoted problems. The evidence for any benefit of ambulatory oxygen is therefore limited despite the theoretical benefits.

Cognitive Behavioral Therapy:A Strategy for Depressive Moods Reduction of in Patients Experiencing Chronic Obstructive Pulmonary Emphysema Disease

Patients with Chronic Obstructive Pulmonary Disease(COPD)often experience difficulty breathing,decreased exercise tolerance and respiratory function as the disease progresses.Pulmonary rehabilitation training can improve respiratory symptoms,increase exercise tolerance and quality of life through exercise stimulation.However,after the end of pulmonary rehabilitation training,the patient's movement behavior is not easy to maintain.Cognitive behavioral therapy(CBT)can effectively enhance cognition,strengthen the motivation of"regular motor behavior",and maintain motor behavior,which can be used as a maintenance strategy for pulmonary rehabilitation training.Objective:To study the effect of cognitive behavioral therapy on the rehabilitation effect and the changing stage of"regular motor behavior"in COPD patients.Methods:30 patients consulted in the Rehabilitation Department of the Third Veterans Hospital of Sichuan Province were interviewed by telephone,and the exercise status and rehabilitation status were recorded and analyzed.From 30 patients,severe and extremely severe(GOLD grade III-IV)in motivation period of"regular exercise behavior"(not starting regular exercise but had exercise thoughts)were randomly divided into two groups.Pulmonary rehabilitation group(CBT-PR group,n=15)conducted one-to-one CBT intervention for 30-40 minutes to discuss the reasons for regular exercise and teach exercise precautions and principles using exercise education form;conventional pulmonary rehabilitation group(conventional PR group,n=15)conducted intensive pulmonary rehabilitation education without consultation and discussion.Both groups underwent 4 weeks of outpatient rehabilitation training,And the regular exercise ability was detected in the first and third months after training(6-Minutes Walking Distance,6-WMD;Short Physical Performance Battery,SPPB),(International Physical Activity Questionnaire,IPAQ),(St.George's Respiratory Scale,St.George's Respiratory Questionnaire,SGRQ),change.

Combination of "low-dose" ribavirin and interferon alfa-2a therapy followed by interferon alfa-2a monotherapy in chronic HCV-infected nonresponders and relapsers after interferon alfa-2a monotherapy

AIM To report on the efficacy, safety and tolerability of interferon alfa-2a combined with a "low dose" of ribavirin for relapsers and non responders to alpha interferon monotherapy.METHODS Thirty-four chronic hepatitis C virus-infected non-responders to interferon alfa2a monotherapy (a course of at least 3 months treatment) and 13 relapsers to interferon alfa 2a monotherapy (a dose of 3 to 6 million units three times per week for at least 20 weeks but not more than 18 months) were treated with the same dose of interferon alfa-2a used before (3 to 6 million units three times per week) and ribavirin (10 mg/ kg daily) for 6 months. In complete responders, interferon alfa-2a was administered for further 6 months at the same dose used before as monotherapy.RESULTS Seven (20.6%) of 34 non-responders stopped the combined therapy due to adverse events, including two patients with histological and clinical Child A cirrhosis. In 17/27 (63%)non-responders, the combined therapy was stopped after three months because of non-response. Ten of the 27 non-responders completed the 1;2-month treatment course. At a mean follow up of 28 months (16- 37 months)after the treatment, 4/10 (15%) previous non-responders still remained complete responders,All 13 previous relapsers completed the 12-month treatment course. At a mean follow up of 22months (9 - 36 months) after treatment, 6/13(46%) the previous relapsers were stillsustained complete responders.CONCLUSION Our treatment schedule of the combined therapy for 6 months of interferon alfa2a with a low dose of ribavirin (10 mg/kg/day)followed by 6 months of interferon alfa-2amonotherapy is able to induce a sustainedcomplete response rate in 15% of non-responders and 46% of relapsers with chronic hepatitis C virus-related liver diseases comparable to those obtained with the standarddoses of ribavirin 1000 - 1200 mg/day.Randomized prospective controlled trials using lower total amounts of ribavirin in combination with interferon should be performed.

Long-term alpha interferon and lamivudine combination therapy in non-responder patients with anti-HBe-positive chronic hepatitis B:Results of an open,controlled trial

AIM: To investigate the safety and efficacy of long-term combination therapy with alpha interferon and lamivudine in non-responsive patients with anti-HBe-positive chronic hepatitis B.METHODS: 34 patients received combination treatment (1 month lamivudine, 12 month lamivudine+interferon, 6month lamivudine), 24 received lamivudine (12 months),24 received interferon (12 months). Interferon was administered at 6 MU tiw and lamivudine at 100 mg orally once daily. Patients were followed up for 6 months after treatment.RESULTS: At the end of treatment, HBV DNA negativity rates were 88 % with lamivudine+interferon, 99 % with lamivudine and 55 % with interferon, (P=0.004, combination therapy vs. interferon, and P=0.001 lamivudine vs.interferon), and serum transaminase normalization rates were 84 %, 91% and 53 % (P=0.01 combination therapy vs. interferon, and P=0.012 lamivudine vs. interferon). Six months later, HBV DNA negativity rates were 44 % with lamivudine+interferon, 33 % with lamivudine and 25 % with interferon, and serum transaminase normalization rates were 61%, 42 % and 45 %, respectively, without statistical significance. No YMDD variants were observed with lamivudine+interferon (vs. 12 % with lamivudine). The combination therapy appeared to be safe. CONCLUSION: Although viral clearance and transaminase normalization are slower with long-term lamivudine+interferon than that with lamivudine alone, the combination regimen seems to provide more lasting benefits and to protect against the appearance of YMDD variants. Studies with other regimens regarding sequence and duration are needed.

Factors influencing the failure of interferon-free therapy for chronic hepatitis C:Data from the Polish EpiTer-2 cohort study

BACKGROUND The introduction of direct-acting antiviral drugs into clinical practice has revolutionized the treatment of chronic hepatitis C,making it highly effective and safe for patients.However,few researchers have analyzed the factors causing therapy failure in some patients.AIM To analyze factors influencing the failure of direct antiviral drugs in the large,multicenter EpiTer-2 cohort in a real-world setting.METHODS The study cohort consisted of patients with chronic hepatitis C treated at 22 Polish centers from 2016-2020.Data collected from the online EpiTer-2 database included the following:hepatitis C virus(HCV)genotype,stage of fibrosis,hematology and liver function parameters,Child-Turcotte-Pugh and Model for End-stage Liver Disease scores,prior antiviral therapy,concomitant diseases,and drugs used in relation to hepatitis B virus(HBV)and/or human immunodeficiency virus(HIV)coinfections.Adverse events observed during the treatment and follow-up period were reported.Both standard and machine learning methods were used for statistical analysis.RESULTS During analysis,12614 patients with chronic hepatitis C were registered,of which 11938(mean age:52 years)had available sustained virologic response(SVR)data[11629(97%)achieved SVR and 309(3%)did not].Most patients(78.1%)were infected with HCV genotype 1b.Liver cirrhosis was diagnosed in 2974 patients,while advanced fibrosis(F3)was diagnosed in 1717 patients.We included patients with features of hepatic failure at baseline[ascites in 142(1.2%)and encephalopathy in 68(0.6%)patients].The most important host factors negatively influencing treatment efficacy were liver cirrhosis,clinical and laboratory features of liver failure,history of hepatocellular carcinoma,and higher body mass index.Among viral factors,genotype 3 and viral load also exerted an influence on treatment efficacy.Classical statistical analysis revealed that treatment ineffectiveness seemed to be influenced by the male sex,which was not confirmed by the multivariate analysis using the machine learning algorithm(random forest).Coinfection with HBV(including patients with on-treatment reactivation of HBV infection)or HIV,extrahepatic manifestations,and renal failure did not significantly affect the treatment efficacy.CONCLUSION In patients with advanced liver disease,individualized therapy(testing for resistance-associated variants and response-guided treatment)should be considered to maximize the chance of achieving SVR.

目的:针对慢性阻塞性肺疾病(chronic obstructive pulmonary disease,COPD)患者存在的症状多样性、自我管理能力不足及心理健康复杂性等特点,探讨计算机化认知行为疗法(computerized cognitive behavioral therapy,CCBT)的干预效果。方法:采用单中心、双盲、随机对照试验,将2023年3—10月于山西医科大学第一医院就诊的72例急性加重期COPD患者纳入研究对象,采用随机数字表法将患者随机分配至观察组(37例)和对照组(35例)。对照组治疗包括常规护理及电话随访,观察组在对照组的基础上接受为期6周的CCBT。采用主要指标(焦虑和抑郁程度)和次要指标[呼吸困难、6分钟步行距离(6-minute walk distance,6MWD)、失眠和疲乏状况]作为评价指标,并于治疗前、中、后进行比较。结果:观察组在CCBT干预6周后的焦虑评分[(53.64±1.46)分]、抑郁评分[(56.59±3.52)分]、呼吸困难评分[(2.14±0.67)分]、失眠评分[(6.19±1.65)分]和疲乏评分[(40.65±0.33)分],均低于干预3周后的焦虑评分[(55.14±2.37)分]、抑郁评分[(58.55±2.33)分]、呼吸困难评分[(2.72±0.45)分]、失眠评分[(7.97±1.57)分]和疲乏评分[(46.09±0.26)分],干预6周后的6MWD[(280.00±8.33)m]高于干预3周后的6MWD[(268.59±7.86)m],差异均有统计学意义(F值分别为16.141、76.745、14.976、46.250、42.337、11.700,P值分别为<0.001、<0.001、<0.001、<0.001、<0.001、0.001);且在干预3周后对照组焦虑评分[(57.43±2.33)分]、抑郁评分[(62.46±2.39)分]、呼吸困难评分[(3.06±0.42)分]、失眠评分[(9.83±1.65)分]及疲乏评分[(47.49±0.33)分]均低于观察组,6MWD[(262.14±9.11)m]高于观察组,差异均有统计学意义(t值分别为―4.564、―7.673、―3.200、―4.881、―3.334、2.992,P值分别为<0.001、<0.001、0.002、<0.001、<0.001、0.004)。干预6周后对照组焦虑评分[(55.04±2.36)分]、抑郁评分[(59.89±2.42)分]、呼吸困难评分[(2.74±0.56)分]、失眠评分[(9.00±1.77)分]和疲乏评分[(43.11±0.33)分]均高于观察组[分别为(53.64±1.46)分、(56.59±3.52)分、(2.14±0.67)分、(6.19±1.65)分、(40.65±0.33)分],6MWD[(275.29±7.85)m]低于观察组[(280.00±8.33)m],差异均有统计学意义(t值分别为―2.354、―4.917、―4.149、―6.988、―5.305、2.467,P值分别为0.021、<0.001、<0.001、<0.001、<0.001、0.016)。结论:基于CCBT的非药物辅助治疗方式,可明显改善COPD患者的症状群相关症状,有效提高患者生活质量;增加干预时间可以显著提高患者治疗效果。

基于态靶辨治理论诊疗慢性阻塞性肺疾病

慢性阻塞性肺疾病是常见的呼吸系统气道慢性病,严重影响患者的生活质量。传统的中医辨证论治体系存在对疾病的发生发展规律认识不足,对检查化验指标改善欠佳的问题。仝小林院士经过多年的临床实践,提出“态靶辨治”的现代中医诊疗体系,并将其用于慢性疾病临床诊疗过程中。基于此,以“态靶辨治”理论为指导,结合临床经验与现代药理学研究成果,将慢性阻塞性肺疾病发病过程分为“痰、阻、瘀、衰”四态(四期),每态下进行分证,并结合治疗靶点,确定各阶段相应的靶方靶药,构建慢性阻塞性肺疾病的态靶辨治体系,为提高该病的中医治疗效果提供新的路径。
