Objective To explore the influence of naloxone hydrochloride injection on levels of IL-6,IL-8,IL-18 and TNF-α in patients with COPD complicated with respiratory failure.Methods A total of 60 COPD patients with respiratory failure were randomly divided into control group (n =30) and experimental group (n =30).The control group was given conventional medical treatment,while the experimental group was treated with naloxone on the basis of the control group.Results After treatment,the inflammatory factors IL-6,IL-8,IL-18,TNF-and blood gas indicators p(CO2) in the experimental group were significantly lower than the control group (P ＜ 0.05),and blood gas indicators p (O2) and pH were significantly higher than the control group (P ＜ O.05).The pulmonary function indexes FVC,FEV1 ％ and PEF in the experimental group were significantly higher than those in the control group (P ＜ 0.05).The hospital stay in the experimental group was significantly shorter than the control group (P ＜ 0.05).The total effective rate of the experimental group was significantly higher than that of the control group (P ＜ 0.05).Conclusion Naloxone hydrochloride injection is effective in the treatment of COPD patients with respiratory failure.

Objective To analyze the risk factors of poor prognosis in patients with extended-spectrum β-lactamase producing enterobacterales(ESBL-E)bloodstream infection,and establish a nomogram prediction model to provide help for clinical diagnosis and treatment.Methods A total of 235 patients with ESBL-E bloodstream infection were collected from the First People's Hospital of Jiande City.According to their prognosis,the patients were divided into survival group(n=211)and death group(n=224).The clinical data of the patients were collected,and the independent risk factors of poor prognosis were screened by multivariate Logistic regression analysis.The nomogram was established and verified.Results The mortality of ESBL-E bloodstream infection patients with shock,respiratory failure,diabetes and leukemia,ICU admission,hypoproteinemia,increased or decreased white blood cells,and thrombocytopenia was higher(P＜0.05).Multivariate Logistic regression analysis showed that combined shock,respiratory failure and leukemia were independent risk factors for death from ESBL-E bloodstream infection.Conclusion The nomogram prediction model of adverse prognostic risk factors in patients with ESBL-E bloodstream infection can provide help for clinicians to judge the poor prognosis in the early stage,and it is of reference significance to take early intervention measures to reduce the mortality of patients.
