Radioimmunoassay was used to determine serum CRP and PCT levels;the observation group was further grouped according to the median of CRP and PCT levels, and serum levels of pro-inflammatory factors, anti-inflammatory factors and stress hormones of high level group and low level group were detected.Results:Serum CRP and PCT levels of observation group were significantly higher than those of normal control group (P<0.05);serum pro-inflammatory factors interleukin-1β (IL-1β), interleukin-6 (IL-6) and interleukin-8 (IL-8) levels of high CRP and PCT level groups within observation group were higher than those of low CRP and PCT level groups (P<0.05), anti-inflammatory factors interleukin-4 (IL-4) and interleukin-13 (IL-13) levels were lower than those of low CRP and PCT groups (P<0.05), and stress hormones angiotensin II (Ang II), aldosterone (ALD) and cortisol (Cor) levels were higher than those of low CRP and PCT level groups (P<0.05).Conclusions:Serum CRP and PCT levels in patients with acute exacerbation of COPD are positively correlated with the inflammatory response extent in the body, and can be used as the auxiliary means for early disease diagnosis, treatment effect evaluation and prognosis judgment.展开更多

Cigarette smoking is the major risk factor for the development of COPD. This study evaluated the levels of cyclophilin B in sputa from patients with COPD and COPD with acute exacerbation (AECOPD). Materials and Methods: Two-dimensional electrophoresis was used for differential display proteomics. Western blotting was used to identify and quantify cyclophilin B in sputum from subjects with AECOPD and COPD. Results: Forty-nine protein spots differed in relative intensity between the AECOPD (n = 6) and COPD (n = 6) subjects. Twenty proteins showed increased expression in the sputum of AECOPD subjects, and 29 proteins were present at lower levels in AECOPD sputum compared with COPD sputum. One of these proteins was associated with cyclophilin B. Cyclophilin B concentrations were lower in sputum from subjects with COPD (n = 4) versus AECOPD (n = 4). Conclusion: The sputum proteomic analysis suggests that changes in various proteins are associated with the development of AECOPD.展开更多

Moreover, 30 healthy individuals who came for physical examinations in the same period were served as the control group. ELISA was used to detect the plasma ET-1 and IL-8 levels, and their correlation was analyzed. The arterial blood gas and coagulation fibrinolysis indicators among the three groups were compared.Results: The plasma ET-1 and IL-8 levels in observation 1 and 2 groups were significantly higher than those in the control group. The plasma ET-1 and IL-8 levels in observation 1 group were significantly higher than those in observation 2 group. PaO2 in observation 1 and 2 groups was significantly lower than that in the control group, while PaCO2 was significantly higher than that in the control group. The comparison of PaO2 and PaCO2 between the two groups was not statistically significant. PT and APTT in observation 1 and 2 groups were significantly shortened when compared with the control group, while TT was significantly delayed. PT in observation 1 group was significantly shortened when compared with observation 2 group. Fbg and t-PA contents in observation 1 and 2 groups were significantly higher than those in the control group. Fbg, t-PA, and D-D contents in observation 1 group were significantly higher than those in observation 2 group.Conclusions:The hypercoagulation state is presenting in patients with AECOPD merged with CHD, with increased ET-1 and IL-8, both of which can play a synergistic effect, and are involved in the pathogenesis.展开更多

Methods: Forty patients with respiratory failure due to acute exacerbation of COPD were enrolled to this study. All patients underwent a comprehensive echocardiographic examination including tissue doppler imaging within first 12 hours of admission. NT-pro BNP serum levels were measured on admission. Patients were followed up for outcome of weaning failure. Results: Right ventricular Tei index was higher in patients with failed weaning in comparison to successfully weaned patients (mean 0.66 versus 0.36, P P = 0.007). There was no difference in serum NT-Pro BNP between successfully weaned patients and patients with weaning failure. Right ventricular Tei index showed higher accuracy in predicting weaning failure than the left ventricular Tei index (AUC 0.932 versus 0.754), while serum NT-Pro BNP showed no discrimination in predicting weaning failure (AUC 0.556). Conclusion: Tei index was superior to NT-ProBNP in prediction of weaning failure in COPD patients.展开更多

There was no difference in serum NT-Pro BNP between successfully weaned patients and patients with weaning failure. Right ventricular Tei index showed higher accuracy in predicting weaning failure than the left ventricular Tei index (AUC 0.932 versus 0.754), while serum NT-Pro BNP showed no discrimination in predicting weaning failure (AUC 0.556). Conclusion: Tei index was superior to NT-ProBNP in prediction of weaning failure in COPD patients.
