ABSTRACT
OBJECTIVE: To study the effect of Epstein-Barr virus(EB) virus infection on acute exacerbation of chronic obstructive pulmonary disease. METHODS: 156 patients with acute exacerbation of chronic obstructive pulmonary disease were divided into two groups, 41 patients with EB virus infection and the group 115 patients without EB virus infection.which colleceted from the Department of Respiratory and Critical Care Medicine, Guizhou Provincial People's Hospital From October 2015 to August 2017. Epstein-Barr virus(EB) DNA was detected by PCR, serum EB antibody IgG and IgM were detected by Elisa, and the expression level of PCT, CRP, IL6,IL-17 and IL-10 in serum were detected by Elisa.Sputum culture and sensitivity were used to analyze the bacteriological characteristics. The characteristics of common pathogens of pulmonary infection were also analyzed in patients with Epstein-Barr virus(EBV) infection,and the therapeutic effects and prognosis were analyzed comprehensively. RESULTS: The EBV-infected AECOPD patients had significantly higher levels of PCT, CRP and IL-6 IL-17, IL-10 in serum of patients with lung infection than those of AECOPD patients with non-EB virus infection. The etiological characteristics of EBV-infected AECOPD patients were mostly G-, The EBV-infected AECOPD patients whose the proportion of drug-resistant bacteria increased, anti-infective treatment time prolonged, complications increased, admitted to intensive care unit increased. Blood gas, the infection of Epstein-Barr virus AECOPD patients was significantly higher PaCO2, PaO2 decreased significantly, and the difference was statistically significant. However, the lung function, no significant difference between the two groups. CONCLUSION: EBV infection aggravates inflammatory response in patients with AECOPD, and promotes the progress and deterioration of the disease.
ABSTRACT
Aim The effects of antibiotics and anticoagulants on mouse peritonaeum were ob-served to explore the factor of the peritoneal dialysis related sclerosing peritoni-tis. Methods The experimental models of peritoneal dialysis were established in miceby infusing different kind of drugs to the peritoneal cavity and the changes of the peri-toneal membrane for each drug at different time were observed by the autopsy and lightmicroscope for several weeks. Results Amikacin, Cefradine, Zinacef, Ciprofloxacin,Heparin and Urokinase could induce sclerosing changes of peritoneal membrane such asloss of peritoneal mesothelum infiltration of inflammatory cells and of proliferation fibrecell.These changes were irreversible after the drugs were stoped.Conclusion Thedrugs commonly used in peritoneal dialysis may in different degree result in peritonealsclerosis.
