Objective To evaluate the efficacy and safety of Salviae miltiorrhizae Injection (include Danshen Injection and Fufang Danshen Injection) for chronic cor pulmonale. Design A systematic review of randomized clinical trials. Method Randomized trials comparing Salviae miltiorrhizae Injection plus routine treatment versus muting treatment alone were identified by electronic and manual searches. No blinding and language limitations were applied. The Jadad scale assessed the methodological quality of trials. Results Thirty randomized trials (n=2 161) were identified. The methodological quality of all trials included was low. The combined results (RR and 95%CI) of symptom scores was 1.20 (1.15 to 1.26). Because of the significant heterogeneity, many other markers of the blood rheology can not be combined. The reason for heterogeneity should include the differences among cases and studies. Because of lacking enough studies, the conclusions about mortality and oxidants/antioxidants markers were not b. Only a few studies had reported adverse events. Conclusions Based in the review, Salviae miltiorrhizae Injection may have positive effect on symptom scores in patients with chronic cor pulmonale. But for mortality, the markers of blood rheology and oxidants/antioxidants, there is no reliable conclusion. However, the evidence is not b due to the general low methodological quality, the variations among studies and experimental markers themselves, and lacking of more relevant and important markers. Further large trials are needed.
ObjectiveTo investigate the effect of pulmonary rehabilitation on pulmonary function,perception of dyspnea and quality of life in stable COPD patients of different severity. Methods300 patients with COPD in stable stage were divided into a moderate COPD group (n=120),a severe COPD group (n=100) and a very severe COPD group (n=80). Each group was randomly subdivided into a control group and a treatment group. The treatment groups received pulmonary rehabilitation for 6 months in addition to usual care,and the control groups received usual care without pulmonary rehabilitation. Pulmonary function(FEV1),6 minute walking distance (6MWD),modified medical research council (mMRC) scale,and acute exacerbation frequency of COPD were compared before and after intervention and among groups. ResultsAfter pulmonary rehabilitation for 6 months,the quality of life score and 6MWD were significantly improved in the treatment groups with moderate,severe,very severe COPD,and the increscent of 6MWD was greatest in the severe COPD patients. The mMRC of the patients with very severe COPD improved significantly after pulmonary rehabilitation(P<0.05). Lung function before and after the intervention in three groups all showed no significant difference (P>0.05). The acute exacerbation frequency of the severe COPD patients was significantly reduced by pulmonary rehabilitation (P<0.05), while there was no significant change in the moderate and very severe groups (P>0.05). ConclusionPulmonary rehabilitation can improve exercise tolerance and quality of life of COPD patients with different severity,reduce acute exacerbation frequency in severe COPD,reduce the dyspnea degree in very severe COPD. Pulmonary rehabilitation is a cost-effective treatment for stable COPD.
ObjectiveTo explore the changes of the B lymphocyte-derived microparticles (BLMPs) in the bronchoalveolar lavage fluid in patients with chronic obstructive pulmonary disease (COPD),and analyze the correlation between BLMPs changes and the stages of the disease. Methods33 COPD patients in acute exacerbation and 12 COPD patients in stable phase in Southwest Hospital,Xinqiao Hospital,and First Affiliated Hospital of Chongqing Medical University between March 2012 and March 2013 were enrolled in the study. 31 subjects who underwent physical examination and bronchoscopy were recruited as control. The lavage fluid specimens were collected through fiberoptic bronchoscopy,then marked with the corresponding antibodies after centrifugation. The numbers of microparticles were analyzed by flow cytometry. ResultsThe number of the BLMPs was significant different among three groups (P<0.05). Compared with the control group and the stable COPD group,the number of BLMPs in the AECOPD group was significantly reduced (P<0.05). Compared with the control group,the number of the BLMPs in the stable COPD group was reduced but with no significant difference (P>0.05). The numbers of BLMPs had no correlation with the smoking history,gender,age and body surface area. ConclusionThe number of BLMPs is reduced in COPD,especially in the acute exacerbation stage,so the reductions of the BLMPs may be associated with the stages of the disease. Smoking,gender,age,body surface area have no effect on the number of BLMPs.
目的 观察噻托溴铵治疗慢性阻塞性肺疾病急性加重期（AECOPD）临床疗效与安全性。 方法 选取 2010 年 1 月－2011年12月入院的69例AECOPD 患者随机分为试验组（A组，n=36）和对照组（B组，n=33），A组在B组常规治疗的基础上吸入噻托溴铵。治疗起始及结束分别观察两组肺功能指标、慢性阻塞性肺疾病评估测试（CAT）评分、血气分析、6分钟步行距离、住院时间及药物不良反应。 结果 两组均显示出一定的临床效果，A组治疗后肺功能指标、CAT评分、血气分析、6分钟步行距离均优于B组，差异均具有统计学意义（P＜0.05）。A组住院时间短于B组（P＜0.05），且无严重不良反应。 结论 AECOPD患者在常规治疗同时吸入噻托溴铵，疗效显著且临床安全性较高。
Objective To investigate the prevalence and predisposing factors of gastroesophageal reflux（GER）in patients with chronic obstructive pulmonary disease（COPD）and its impacts on the frequency of COPD exacerbations.Methods 50 patients with acute exacerbation of COPD were enrolled in the study.All patients filled a modified version of clinically validated standardized Mayo Clinic GER questionnaire.Pulmonary function tests（PFT），body mass index（BMI），serum albumin，and medications were recorded.The patients were divided in to GER group（13 patients with GER symptoms longer than one year and diagnosed GER by gastroscope） and non-GER group（37 patients without GER symptoms）.Results There were no significant differences in the BMI，serum albumin，use of inhaled steroids and theophylline between the two groups.Forced expiratory volume in one second as a percentage of the predicted value（FEV1%pred）（37% vs 38.3%，P=0.608.），residual volume % predicted（123.4 % vs 137.8%，P=0.222），and residual volume to total lung capacity（139.4% vs 141.5%，P=0.798） were not significantly different between the two groups.The number of COPD exacerbations per year was significantly higher in patients with GER compared to patients without GER（4.5 vs 1.3，P=0.006）.Conclusions The severity of airflow obstruction and the hyperinflation is unlikely to contribute to the development of GER.Patients with GER experience significantly more exacerbations per year when compared to patients without GER，suggesting more highlight warrant in treatment of GER in COPD patients.
根据慢性阻塞性肺疾病全球创议(GOLD)的定义，慢性阻塞性肺疾病急性加重(AECOPD)是“在COPD的自然病程中发生的事件，气紧、咳嗽或／和咳痰等基础症状加重超出正常的日间变异的范围，急性发病，可能需要改变常规的治疗”[1]。AECOPD意味着对医疗卫生资源耗用的增加，如非预约的就医、使用药物增加，使用抗生素或口服皮质激素甚至住院，等等。仅仅依据是否占用卫生资源来定义AECOPD并不适当，这一点还要取决于医疗卫生资源的可获得性，同时有研究提示部分AECOPD可以是自限性的，特别是轻度急性加重。另一方面，占用医疗卫生资源的形式可以大致评估AECOPD的严重程度，如需要增加常规的吸人性药物常常意味着轻度AECOPD，需要短程口服抗生素或糖皮质激素意味着中度AECOPD，而需要住院者多为重度AECOPD。AECOPD是导致COPD患者健康状态降低乃至死亡的主要原因，也是耗用医疗卫生资源从而构成COPD疾病负担的主要部分，需要采用有力的干预措施以降低其发生率[2]。
Objective To evaluate the effects of indoor temperature and relative humidity on acute exacerbations of chronic obstructive pulmonary disease（AECOPD）.Methods A total of 70 moderate to very severe COPD patients were recruited.The data including indoor temperature and relative humidity twice daily，increase over their stable symptoms in "major" symptoms（dyspnea，sputum purulence，sputum amount） and "minor" symptoms（nasal discharge/congestion，sore throat，cough），and adjustment of medication were recorded on diary cards.All data were collected from Jan 2005 to Dec 2005 by telephone inquiring or home visiting.Furthermore，the corresponding median outdoor temperature，relative humidity and air pressure from atmosphere bureau were compared with indoors parameters to examine the different effects on AECOPD.Results Fifty-five cases completed the whole investigation.Indoor temperature and relative humidity were both risk factors when logistic regression was used to evaluate the effect.Our research showed that AECOPD was significantly related to indoor and ourdoor environment factors.The correlation coefficient of all factors were r=－0.686（indoor temperature），r=－0.671（outer temperature），r=0.105（indoor humidity），r=－0.115（outer humidity），r=0.545（atmospheric pressure） respectively.Conclusions The indoor temperature and relative humidity，especially low temperature and high relative humidity，had important effects on AECOPD of moderate to very severe patients.It may be helpful to prevent AECOPD by adjusting the indoor temperature and relative humidity.
