[ABSTRACT]AIM:Toobservetheeffectofazithromycinontheratswithchronicobstructivepulmonarydisease ( COPD) , and to explore the underlying mechanism about the airway inflammation and mucus hypersecretion.METH-ODS:Male SD rats were randomly divided into normal control group, COPD model group, azithromycin treatment group. The COPD model was established by the method of cigarette smoking combined with intratracheal injection of LPS.Patho-logical changes of the bronchi and lung tissues of the rats were observed with HE staining.Pulmonary ventilation function in the rats was detected with pulmonary function instrument.The levels of IL-8, IL-17 and TNF-αin bronchoalveolar lavage fluid (BALF) were measured by ELISA.The expression of MUC5ac and TLR4 at mRNA and protein levels in bronchi and lung tissues was determined by real-time PCR and Western blot.RESULTS:HE staining showed that the changes of bron-chi and lung tissues in model group were consistent with typical pathological manifestations of COPD .Compared with model group, these changes were alleviated in treatment group.The pulmonary functions in model group were significantly de-creased compared with control group.The levels of IL-8, IL-17 and TNF-αin the BALF in model group were significantly increased compared with control group (P<0.05).The expression of MUC5ac and TLR4 at mRNA and protein levels in model group was significantly higher than that in control group (P<0.05).Compared with model group, the degree of the descent in pulmonary function in treatment group was significantly lessened.Compared with model group, the levels of IL-8, IL-17 and TNF-αin treatment group were significantly inhibited (P<0.05).Furthermore, the expression of MUC5ac and TLR4 at mRNA and protein levels in treatment group was significantly lower than that in model group ( P<0.05 ) . CONCLUSION:Azithromycin decreases the levels of IL-8, IL-17 and TNF-αin the BALF of COPD model rats, inhibits the protein expression of MUC5ac and TLR4 in the lung tissues, thus playing a preventive and therapeutic role to reduce airway inflammation and airway mucus hypersecretion.

Objective:To establish a 180-day mortality predictive score based on frailty syndrome in elderly sepsis patients [elderly sepsis score (ESS)].Methods:A prospective study for sepsis patients aged 60 years and above who were admitted to a medical intensive care unit of the General Hospital of Southern Theatre Command from January 1st, 2018 to December 31st, 2018 was conducted. Univariate analysis was performed on 19 independent variables including gender, age, body mass index (BMI), tumor, charlson comorbidity index (CCI), activity of daily living (ADL), instrumental activity of daily living (IADL), mini-mental state examination (MMSE), geriatric depression scale (GDS), clinical frail scale (CFS), sequential organ failure assessment (SOFA), Glasgow coma scale (GCS), acute physiology and chronic health evaluation (APACHEⅡ, APACHEⅣ), modified NUTRIC score (MNS), multiple drug resistance (MDR), mechanical ventilation (MV), continuous renal replacement therapy (CRRT) and palliative care. Continuous independent variables were converted into classified variables. Multivariate binary regression analysis of risk factors was conducted to screen independent risk factors which affecting 180-day mortality in elderly sepsis patients. Then a 180-day mortality predictive score was established, and the discrimination of the mortality of patients using CFS, SOFA, GCS, APACHEⅡ, APACHEⅣ, MNS scores were compared.Results:A total of 257 patients were enrolled, with a 180-day mortality of 60.7%. Univariate analysis showed that age, tumor, CCI, ADL, IADL, MMSE, CFS, SOFA, GCS, APACHEⅡ, APACHEⅣ, MNS, MDR, MV, CRRT, palliative care were risk factors of 180-day mortality in elderly sepsis patients [age: odds ratio ( OR) = 1.027, 95% confidence interval (95% CI) was 1.005-1.050, P = 0.018; tumor: OR =2.001, 95% CI was 1.022-3.920, P = 0.043; CCI: OR = 1.193, 95% CI was 1.064-1.339, P = 0.003; ADL: OR = 0.851, 95% CI was 0.772-0.940, P = 0.001; IADL: OR = 0.894, 95% CI was 0.826-0.967, P = 0.005; MMSE: OR = 0.962, 95% CI was 0.937-0.988, P = 0.004; CFS: OR = 1.303, 95% CI was 1.089-1.558, P = 0.004; SOFA: OR = 1.112, 95% CI was 1.038-1.191, P = 0.003; GCS: OR = 0.918, 95% CI was 0.863-0.977, P = 0.007; APACHEⅡ: OR = 1.098, 95% CI was 1.053-1.145, P < 0.001; APACHEⅣ: OR = 1.032, 95% CI was 1.020-1.044, P < 0.001; MNS: OR = 1.315, 95% CI was 1.159-1.493, P < 0.001; MDR: OR = 2.029, 95% CI was 1.197-3.437, P = 0.009; MV: OR = 6.408, 95% CI was 3.480-11.798, P < 0.001, CRRT: OR = 2.744, 95% CI was 1.529-4.923, P = 0.001, palliative care: OR = 5.760, 95% CI was 2.177-15.245, P < 0.001]. By binary regression analysis, CFS stratification ( OR = 1.934, 95% CI was 1.267-2.953, P = 0.002), MV ( OR = 4.531, 95% CI was 2.376-8.644, P < 0.001), CRRT ( OR = 2.471, 95% CI was 1.285-4.752, P = 0.007), palliative care ( OR = 6.169, 95% CI was 2.173-17.515, P = 0.001) were independent risk factors of 180-day mortality in elderly patients with sepsis. The model of "ESS = 0.660×CFS stratification+1.511×MV+0.905×CRRT+1.820×palliative care" was established. Receiver operating characteristic curve (ROC curve) analysis showed that the area under the ROC curve (AUC) for predicting 180-day mortality by ESS was 0.785 (95% CI was 0.730-0.834, P < 0.001). When the best cut-off value was 2.2 points, its sensitivity was 78.9%, specificity was 70.3%, the positive predictive value was 80.4%, and the negative predictive value was 68.3%. Simplified ESS was defined as "0.5×CFS stratification+1.5×MV+1×CRRT+2×palliative care". ROC curve analysis showed that AUC for predicting 180-day mortality by simplified ESS was 0.784 (95% CI was 0.729-0.833, P < 0.001). When the best cut-off value was 2.0 points, sensitivity was 76.9%, specificity was 70.3%, the positive predictive value was 80.0%, and the negative predictive value was 66.4%. Compared with CFS, SOFA, GCS, APACHEⅡ, APACHEⅣ and MNS, ESS had a significant difference in discriminating 180-day mortality in elderly patients with sepsis (AUC was 0.785 vs. 0.607, 0.607, 0.600, 0.664, 0.702, 0.657, 95% CI: 0.730-0.734 vs. 0.537-0.678, 0.537-0.677, 0.529-0.671, 0.598-0.730, 0.638-0.766, 0.590-0.725, all P < 0.05). Conclusions:CFS, MV, CRRT, and palliative care are independent risk factors of 180-day mortality in elderly patients with sepsis. We established ESS based on these risk factors. The ESS model has good discrimination and can be used as a reference and assessment tool for prediction and treatment guidance in elderly patients with sepsis.

INTRODUCTION: The purpose of this study was to assess the application of the early warning score system (EWS-S) and gauge physician awareness, perceptions of necessity and attitudes regarding these tools based on previously experienced unnoticed clinical deterioration (CDET). METHODS: A cross-sectional survey was carried out via an online questionnaire at a large 3,500-bed Class 3A general hospital in China. A total of 299 physicians of adult general wards were asked to answer a translated questionnaire that was localised from the original version. Demographic profiles of patients were included as well as three other sections assessing awareness of CDET/EWS-S and gauging attitudes towards and perceptions of the necessity of EWS-S at our hospital. RESULTS: A high level of physician awareness of the CDET problem was observed. Most physicians knew about the existence of a systematic assessment tool for clinical application. Physicians with previous experience in reanimation, unplanned transfer to intensive care unit (UTICU) and/or death tended to consider EWS-S necessary in attentive and well-trained staff (p < 0.05). Physicians who had previous experience with UTICU were more likely to recommend implementing EWS-S in their wards compared with those without such experience (p < 0.05). CONCLUSION Most physicians have positive attitudes towards EWS-S. However, their awareness should be further heightened. Physicians who had previous experience with CDET/UTICU were more likely to employ EWS-S in their clinical practices. To better facilitate the implementation of EWS-S in Chinese hospitals, existing facilities, policy supports, standardised managements and the development of information systems should be strengthened.
