Clinical characteristics and risk factors of patients with uremic encephalopathy / 中华急诊医学杂志

Objective:To analyze and compare clinical characteristics and risk factors of patients with uremic encephalopathy (UE).Methods:A retrospective analysis was performed from January 2014 to January 2019 in our hospital. Seventy patients diagnosed with chronic kidney disease (CKD) at the end stage (according to diagnosis standard of CKD) complicated with UE were classified into the UE group. In principle matching with sex, age and duration of disease, seventy patients with chronic kidney disease at the end stage but without UE were classified into the non-UE group (NUE group). The demographic data, laboratory examination, CT or MRI examination were recorded and analyzed by using t or χ 2 test. In addition, independent risk factors of patients with UE were analyzed by using Logistic model. Results:A total of 70 patients in the UE group and 70 patients in the NUE group were collected. The proportion of patients with a history of alcohol comsumption, chronic obstructive pulmonary disease and polycystic kidney disease were higher in the UE group than in the NUE group ( P<0.05). There were no significant differences in hypertension, diabetes, and coronary artery disease history between the two groups ( P>0.05). The proportion of cerebral focus and lesions for brain white matter revealed by head CT or MRI in the UE group were significantly higher than that in the NUE group ( P<0.05). The serum NLR and UA levels in the UE group were higher than those in the NUE group ( P<0.05), but the serum ALB and FT3 levels in the UE group were lower than those in the NUE group ( P<0.05). Logistic regression analysis showed that serum NLR, ALB and FT3 levels were independent risk factors for UE patients. Conclusions:Cerebral focus and lesions for brain white matter revealed by CT or MRI are typical abnormal in UE patients. The serum NLR, FT3 and ALB levels are independent risk factor for UE patients.

Effects of Ulinastatin on pulmonary vascular endothelium permeability and respiratory function in ;patients with extrapulmonary acute respiratory distress syndrome / 实用医学杂志

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.

Risk factors and etiology of multiple drug-resistant bacterial infection of stroke-associated pneumonia pa-tients in intensive care unit / 实用医学杂志

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.
