Objective To observe the effects of salmeterol / fluticasone combined with tiotropium in the treatment of sever to very sever COPD. Methods Eighty patients with severe to very severe stable COPD were recruited from outpatient of Central Hospital of Cangzhou between May 2008 and October 2009. The subjects were randomly divided into a salmeterol /fluticasone group and a combination group. The salmeterol / fluticasone group received salmeterol / fluticasone propionate, and the combination group received the combination therapy of tiotropium and salmeterol / fluticasone propionate. All patients had received the treatment for 12 months. At baseline and at the end of 1-month, 3-month, 6-month, 12-month, lung function ( FEV1 , IC and FVC) , six-minute walk distance and the St. George’s Respiratory Questionnaire ( SGRQ) score were assessed. The number of exacerbations and the time to the first exacerbation were also recorded. Results At every visit, lung function ( FEV1 , IC and FVC) , six-minute walk distance and the SGRQ score were improved in both groups compared with baseline ( Plt;0. 05) , especially in the combination group ( Plt;0.05) . Compared with the salmeterol /fluticason, the combination therapy with tiotropium significantly decreased the incidence of exacerbations and prolonged the time to the first exacerbation ( Plt;0.05) . And there was no significant difference between two groups in adverse effects ( Pgt;0.05) . Conclusions The combination therapy with salmeterol / fluticasone propionate and tiotropium was superior to salmeterol / fluticasone propionate in treatment of sever to very severe stable COPD patients in improving lung function, exercise tolerance, and quality of life, without additional adverse effects.
Abstract： Objective To find out goodness and weakness by comparing totally thoracoscopic surgery （TTS）and median sternotomy （MS）with cardiopulmonary bypass for pediatric open heart operation. Methods One hundred and fortyseven patients with ventricular septal defect(VSD) and atrial septal defect(ASD) were randomly divided into two groups according to operative methods, TTS group: patients were operated by totally thoracoscopy; MS group: patients were operated by median sternotomy with cardiopulmonary bypass. The clinical records from two groups were compared on operative effect, complications, hospitalization, ventilation time,variations of main data of blood routine test, drainage of pleura cavity, blood loss and transfusion, and pulmonary function. Results There were no death in two groups. There was VSD residual leak the same day after operation which was cured by TTS in one patient of TTS group. There was one case which bleeding was stopped by second operation in MS group. Followup visit were made to 41 patients for 3 months, no heart murmur was detected. The ultrasonic cardiography (UCG) showed that correcting of VSD and ASD were good and had no residual leak. The hospitalization,aortic clampping time, ventilation time and variations of main data of blood routine test, drainage of pleura cavity, blood transfusion and blood loss in TTS group had no significant difference to those in MS group (Pgt;0.05). Operating times was longer in TTS group than that in MS group, while stays in the intensive care unit were shorter in TTS group than that in MS group (Plt;0.01). Preoperative and 3 months postoperative pulmonary function of both teams had no statistically significant difference in two groups (Pgt;0.05). Conclusion TTS is a safe and effective method to pediatric VSD and ASD as MS is.
Lung transplantation has been a standard treatment option for patients with end-stage lung disease. However, the demand for donor lungs exceeds the poor of available organs, resulting in considerable waiting list mortality. Among all the useful methods so far, ex vivo lung perfusion (EVLP) has been considered a useful technique in lung transplantation, which helps prolong donor lung preservation and repair donor lung injuries. Current studies have demonstrated EVLP can evaluate the donor lung function continuously and provide platform for pharmaceutical or even gene therapy. Moreover, EVLP improves the function of marginal donor lungs and increases the quantity of lungs meeting the transplant criteria, which could extend the donor pool. This article reviews the clinical application and research progress of EVLP in lung transplantation.
Abstract： The principles of 2010 National Comprehensive Cancer Network（NCCN） clinical practice guidelines in non-small cell lung cancer address that anatomic pulmonary resection is preferred for the majority of patients with non-small cell lung cancer and video-assisted thoracic surgery (VATS) is a reasonable and acceptable approach for patients with no anatomic or surgical contraindications. By reviewing the literatures on general treatment, pulmonary segmentectomy, pulmonary function reserve, and the anatomic issue of early stage non-small cell lung cancer surgery, the feasibility and reliability of thoracoscopic pulmonary segmentectomy are showed.
0bjective To investigate the prevalence of gastroesophageal reflux(GER)in acute exacerbation of chronic obstructive pulmonary disease(AECOPD)and to explore the influence of GER on the acidity of airway and pulmonary ventilation function in AECOPD patients．Methods Sixty-five hospitalized AECOPD patients and 20 healthy volunteers were enrolled in this study．According to “GER survey”questionnaire，AECOPD patients were allocated into GER group and non-GER group and expired breath condensate(EBC)pH and pulmonary ventilation function were detected．Breath condensate samples were collected using a specially designed condensing chamber(EcoScreen，Germany)．Results About 30.8％ (20／65)AECOPD patients were complicated with GER．EBC pH was lowest in GER group，middle in non-GER group and highest in the control group[6.oo±0.75 VS 6.76±0.77 and 7.97±0.12，both Plt;0.05)．The pulmonary ventilation function(FEV1、FEV1％pred)in AECOPD patients with GER were lower than those without GER(both Plt;0.05)．Conclusions There iS a high prevalence of GER in AECOPD patients．And the airway pH is reduced in AECOPD patients，especially when complicated with GER，which may play an important role in the development of COPD．
Objective To investigate the rate of pulmonary function test, medication treatment, and relevant factors among patients with chronic obstructive pulmonary disease (COPD) aged 40 years or older in community of Guangdong Province, and to provide evidences for targeted intervention of COPD. Methods A multistage stratified cluster sampling was conducted in the community residents, who participated in the COPD surveillance project of in Guangdong Province during 2019 to 2020. A total of 3384 adults completed questionnaire and pulmonary function test. The Rao-Scott χ2 test based on complex sampling design, and non-conditional Logistic regression were used to explore possible influencing factors of pulmonary function test and medication treatment in COPD patients. Results Out of the 3384 adults, 288 patients with COPD were confirmed, including 253 males (87.8%) and 35 females (12.2%), and 184 patients (60.4%) were over 60 years old or more. The pulmonary function test rate was 10.7% [95% confidence interval (CI) 6.8% - 14.6%], and medication treatment rate was 10.6% (95%CI 7.0% - 14.1%). The results showed that wheezing, awareness of COPD related knowledge and pulmonary function test were related to whether COPD patients had pulmonary function test (P<0.05). Wheezing and personal history of respiratory diseases were related to medication treatment rate (P<0.05). Conclusions The rates of pulmonary function test and medication treatment among COPD patients aged 40 years or older are low. Health education about COPD should be actively carried out, and the screening of individuals with a history of respiratory diseases and respiratory symptoms should be strengthened so as to reduce the burden of COPD diseases.
【Abstract】 Objective To explore the clinical value of vibration response imaging ( VRI) in patients with chronic obstructive pulmonary disease ( COPD) . Methods 255 COPD patients and 78 healthy volunteers were enrolled and lung function test and VRI examination were performed. The parameters of VRI included dynamic image grades, vibration energy graph grades, vibration value, quantitative lung data ( QLD) of right lung, and crack counts. Results The VRI parameters of the COPD group were as follows, ie.dynamic image grades of 3. 07 ±1. 34, graph grades of 7. 81 ±3. 27, vibration value of 1. 57 ±0. 46, QLD of( 49. 5 ±12. 6) % , crack counts of 5. 27 ±7. 74. The VRI parameters of the control group were as follows, ie.dynamic image grades of 1. 14 ±1. 00, graph grades of 2. 24 ±1. 27, vibration value of 1. 87 ±0. 40, QLD of( 44. 0 ±7. 7) % , crack counts of 0. 21 ±0. 88. There were significant differences in all parameters between the two groups ( all P lt;0. 05) . There was a linear relationship between VRI and FEV1% pred ( r = 0. 548,P lt;0. 01) . The model of the linear regression was Y =80. 833 - 2. 735X1 - 5. 406X2 ( Y: FEV1% pred, X1 :VRI graph grades, X2 : dynamic image grades) . Conclusion VRI is a promising method to diagnose and assess the severity of COPD.
