  • Changes of Pulmonary Surfactant Protein D in Serum and Lung Tissue of Rats with Chronic Obstructive Pulmonary Disease

    Objective To investigate the relationship of pulmonary surfactant protein D( SP-D) with chronic obstructive pulmonary disease ( COPD) by measuring SP-D level in serum and lung tissue of rats with COPD.Methods The rat COPD model was established by passive smoking as well as intratracheal instillation of lipopolysaccharide ( LPS) . Thirty male SD rats were randomly divided into a control group, a LPS group, and a COPD group( n =10 in each group) . The pathologic changes of lung tissue and airway were observed under light microscope by HE staining. Emphysema changes were evaluated by mean linear intercept ( MLI) of lung and mean alveolar number ( MAN) . The level of SP-D in serum was measured by enzymelinked immunosorbent assay ( ELISA) . The expression of SP-D in lung tissue was detected by Western-blot and immunohistochemistry.Results The MLI obviously increased, and MAN obviously decreased in the COPD group compared with the control group ( Plt;0.05) . There was no significant difference in the MLI and MAN between the LPS group and the control group ( Pgt;0.05) . The serum SP-D level was ( 49.59 ±2.81) ng/mL and ( 53.21±4.17) ng/mL in the LPS group and the COPD group, which was significantly higher than that in the control group [ ( 42.14±2.52) ng/mL] ( Plt;0.05) . The expression of SP-D in lung tissue was 0.56±0.01 and 0.63±0.01 in the LPS group and the COPD group, which was also obviously ber than that in the control group ( 0.39 ±0.01) ( Plt;0.05) .Meanwhile the SP-D levels in serumand lung tissue were higher in the COPD group than those in the LPS group ( Plt;0.05) . The levels of SP-D between serum and lung tissue were positively correlated in all three groups ( r=0.93, 0.94 and 0.93, respectively, Plt;0.01) .Conclusion Both the SP-D level in serum and in lung tissue increase significantly in COPD rats and correlate well each other, which suggests that SP-D may serve as a biomarker of COPD.

    ObjectiveTo translate the King’s Brief Interstitial Lung Disease (K-BILD) to Chinese, so as to provide an well reliability and validity assessment instrument for health status of patients with interstitial lung disease.MethodsBrislin’s transition model, six expert’s panel and pre-survey were used for initial Chinese version of K-BILD. Items analysis, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), internal consistency reliability and test-retest reliability were used for validity and reliability test with 122 respondents.ResultsTen-item Chinese version of K-BILD were proved to have great psychometric qualities, two factors were extracted by EFA, which could explain 63.35% of the total variance. Furthermore, the CFA demonstrates the fit indices of two-factors mode: χ2/df=0.797, RMSEA=0.000, NFI=0.848, IFI=1.048, CFI=1.000, TLI=1.071. Cronbach’s α and Guttman Split-half were 0.893 and 0.861, respectively. Besides, the test-retest reliability of the scale was 0.805.ConclusionThe Chinese version of K-BILD scale has good validity and reliability, which is applicable for health status assessment in patient with interstitial lung disease.

  • Effects of Thyroid Hormone Replacement Therapy on Critically Ill COPD Patients with Decreased Serum Thyroid Hormone

    Objective To investigate the therapeutic effects of thyroid hormone replacement on critically ill COPD patients with low serum thyroid hormone. Methods Sixty-seven critically ill patients with acute exacerbation of COPD ( AECOPD) , and complicated with respiratory and/ or heart failure and low serum thyroid hormone, admitted from July 2008 to June 2011, were recruited for the study. They were randomly divided into an intervention group ( n = 34) and a control group ( n = 33) . The control group received conventional treatment and the intervention group received conventional treatment plus additional thyroid hormone replacement therapy. Results Compared with the control group, the overall efficacy of the intervention group was not significantly different ( 88. 2% vs. 81. 8% , P gt; 0. 05) , while average effective time was significantly shorter [ ( 9. 6 ±2. 5) d vs. ( 12. 3 ±2. 8) d, P lt; 0. 05] . The post-treatment serum FT3 , FT4 , TT4 , and h-TSH levels were significantly higher in the intervention group than those in the control group, and significantly higher than baseline ( P lt;0. 05) . Conclusions For AECOPD patients complicated with respiratory and/or heart failure and low serum thyroid hormone, thyroid hormone supplement at low dosage will help to improve serumthyroid hormone level, and promote early recovery.

  • 慢性阻塞性肺疾病与细菌感染

    20 世纪五六十年代, 一些学者认为反复细菌感染是COPD 发病机制中的重要因素, 之后吸烟被证实是更为主要的病因。到七八十年代时, 越来越多的学者认为细菌感染可能只是COPD 发病中有较小致病意义的一个附带现象, 而更有可能是导致慢性阻塞性肺疾病急性加重( AECOPD) 的原因并因此作用于COPD 的发展。近年来, 新的分子学、细胞学及免疫学技术的应用使得学者们对于细菌感染在COPD中的作用又有了许多新的认识。

  • Effects of the budesonide nebulization in the treatment of mechanically ventilated patients with chronic obstructive pulmonary disease

    Objective To explore the effect of budesonide nebulization in the treatment of mechanically ventilated patients with chronic obstructive pulmonary disease(COPD).Methods A total of 25 intubated and ventilated COPD patients complicated with respiratory failure was randomly divided into two groups.The control group consisted of 12 patients received salbutamol nebulization on the routine treatment.The budesonide group consisted of 13 patients received budesonide plus salbutamol nebulization on the routine treatment.Variables such as tumor necrosis factor-α(TNF-α) and interleukin-8(IL-8) in the bronchoalveolar lavage fluid(BALF) , incidence of ventilation-associated lung injury(VALI) , days of mechanical ventilation ,, days of hospitalization and survival rate were measured and compared.Results The survival rate and incidence of VALI were not different significantly between the two groups.However , the levels of TNF-α and IL-8 in BALF of the control patients were significantly lower than those in the budesonide group[ ( 1.2±0.2 ) mg/L vs ( 1.5±0.4 ) mg/L ,( 85.7±26.5 )( 125.6±30.4 ), both Plt;0.05).And the days of mechanical ventilation and hospitalization were statistically shorter in the budesonide group compared with the control group[ (7.2±2.5 ) d vs ( 10.5±6.2 ) d , (10.5±4.7 ) d vs (15.8±6.6 ) d , both Plt;0.05].Conclusion Our data suggest that nebulization of budesonide can suppressed the pulmonary inflammation and decreased days of the mechanical ventilation and hospitalization in mechanically ventilated COPD patients.

  • Risk factors associated with failure of noninvasive positive pressure ventilation in acute respiratory failure due to acute exacerbation of chronic obstructive pulmonary disease

    Objective To analyze the risk factors of treatment failure by noninvasive positive pressure ventilation (NPPV) in patients with acute respiratory failure (ARF) due to acute exacerbation of chronic obstructive pulmonary disease (AECOPD), and explore the best time that NPPV be replaced by invasive ventilation when NPPV failure occurs. Methods The data of patients with ARF due to AECOPD who were treated with NPPV from January 2013 to December 2015 were retrospectively collected. The patients were divided into two groups: the NPPV success group and the NPPV failure group (individuals who required endotracheal intubation or tracheotomy at any time). The Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ score was analyzed; the Glasgow Coma Scale score, respiratory rate (RR), pH value, partial pressure of oxygen (PaO2), PaO2/fraction of inspired oxygen (FiO2) ratio, and partial pressure of carbon dioxide were also analyzed at admission, after 2 hours of NPPV, and after 24 hours of NPPV. Results A total of 185 patients with ARF due to AECOPD were included. NPPV failed in 35.1% of the patients (65/185). Multivariate analysis identified the following factors to be independently associated with NPPV failure: APACHEⅡscore≥30 [odds ratio (OR)=20.603, 95% confidence interval (CI) (5.309, 80.525), P<0.001], RR at admission≥35 per minute [OR=3.723, 95%CI (1.197, 11.037), P=0.020], pH value after 2 hours of NPPV<7.25 [OR=2.517, 95%CI (0.905, 7.028), P=0.070], PaO2 after 2 hours of NPPV<60 mm Hg (1 mm Hg=0.133 kPa) [OR=3.915, 95%CI (1.374, 11.508), P=0.010], and PaO2/FiO2 after 2 hours of NPPV<200 mm Hg [OR=4.024, 95%CI (1.542, 11.004), P=0.010]. Conclusion When patients with ARF due to AECOPD have a higher severity score, have a rapid RR at admission, or fail to improve in terms of pH and oxygenation after 2 hours of NPPV, the risk of NPPV failure is higher.
