Ojective To determine the risk factors and the clinical distribution of multiple drug resistant bacteria in stroke- associated pneumonia (SAP) patients with multiple drug-resistant bacterial infections from in-tensive care unit, providing guidance for clinical treatment of SAP. Methods A retrospective study was de-signed to analyze the clinical data of the SAP patients from January 2012 to December 2015. Univariate analysis and multivariable regression analysis were taken for risk factors of MDR infections , and investigated the distribu-tion and drug resistance of MDR. Results There were 183 SAP patients, of which 131patients (71.6%) had MDR infection. There are 193 MDR strains in the 131 patients , the first 5 MDR strains were Acinetobacter bau-mannii, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus and Escherichia coli. MDR in-fection is highly associated with sever unconsciousness , time of stay in ICU longer than 7 days , ventilator time longer than 7 days and late-onset pneumonia and the difference was significant (P < 0.05). Conclusion SAP patients with MDR bacterial infections are in association with the following risk factors: sever unconsciousness , time of stay in ICU longer than 7 days, ventilator time longer than 7 days and late-onset pneumonia. The rate of MDR bacterial infections was high , and these MDR strains were widely different degrees of resistance to many antibiotics.

Objective To observe the effects of Ulinastatin on pulmonary vascular endothelium permeability and respiratory function in patients with extrapulmonary acute respiratory distress syndrome(ARDS exp). Methods The data of 39 patients with ARDS exp were retrospectively analyzed.According to whether treated with Ulinastatin or not, all patients were divided into Ulinastatin group(n = 21)and control group(n = 18); The level of extravascular lung water index (EVLWI), pulmonary vascular permeability index(PVPI) and respiratory function were measured before and after the treatment. Results The mortality rate of Ulinastatin group was lower than that of control group (28.6% vs 38.9%). The time of decreasing EVLWI, PVPI and improving PaO2/FiO and respiratory function in Ulinastatin group was shorter than that of control group, and the effect was superior. Conclusion Ulinastatin could reduce EVLWI and PVPI, improve pulmonary compliance and oxygenation, and reduce mortality rate in patients with extrapulmonary acute respiratory distress.

From the point of view of ethics review work situation of our country, the existing capacity of our review of ethical problems in development are analyzed, a preliminary summary of the Chinese medicine ethics review ca-pacity development, systematically analyzes the Assessment Human Research Protection System of TCM and Chinese medicine clinical research ethics review platform evaluation work, and to improve the ethical review system to perfect supervision system, improve the medical ethics review standards and guidelines, carrying out the innovation and con-struction of ethical review professional knowledge training, to promote Chinese medicine ethics review certification and accreditation system construction work and Chinese medical ethics review of the clinical research objective, the practice of ethical review management of Chinese medicine are discussed.

OBJECTIVETo assess the effects of continuous blood purification (CBP) on extravascular lung water and respiratory function in patients with extrapulmonary acute respiratory distress syndrome (ARDSexp).
METHODSThe data of 31 patients with ARDSexp admitted in our department were retrospectively analyzed.Sixteen of the patients received CBP, and the other 15 patients did not (control group). The level of extravascular lung water index (EVLWI), pulmonary vascular permeability index (PVPI), and respiratory function were measured before and after CPB.
RESULTSThe mortality rate was significantly lower in CBP group than in the control group (12.5% vs 33.3%, P<0.05). The patients in CPB group showed markedly earlier and significantly greater improvements in EVLWI, PVPI, PaO2/FiO, and respiratory function than the control patients (P<0.05).
CONCLUSIONCBP can reduce EVLWI and PVPI, improve pulmonary compliance and oxygenation, and reduce mortality rate in patients with ARDSexp.

Few studies have described the key features and prognostic roles of lung microbiota in patients with severe community-acquired pneumonia (SCAP). We prospectively enrolled consecutive SCAP patients admitted to ICU. Bronchoscopy was performed at bedside within 48 h of ICU admission, and 16S rRNA gene sequencing was applied to the collected bronchoalveolar lavage fluid. The primary outcome was clinical improvements defined as a decrease of 2 categories and above on a 7-category ordinal scale within 14 days following bronchoscopy. Sixty-seven patients were included. Multivariable permutational multivariate analysis of variance found that positive bacteria lab test results had the strongest independent association with lung microbiota (R2 = 0.033; P = 0.018), followed by acute kidney injury (AKI; R2 = 0.032; P = 0.011) and plasma MIP-1β level (R2 = 0.027; P = 0.044). Random forest identified that the families Prevotellaceae, Moraxellaceae, and Staphylococcaceae were the biomarkers related to the positive bacteria lab test results. Multivariable Cox regression showed that the increase in α-diversity and the abundance of the families Prevotellaceae and Actinomycetaceae were associated with clinical improvements. The positive bacteria lab test results, AKI, and plasma MIP-1β level were associated with patients' lung microbiota composition on ICU admission. The families Prevotellaceae and Actinomycetaceae on admission predicted clinical improvements.
