OBJECTIVE: To assess the impact of albumin (Alb) administration on the prognosis of patients with acute kidney injury (AKI). METHODS: Clinical data of AKI patients in the intensive care unit (ICU) were retrospectively analyzed from the American Medical Information Mart of Intensive Care-IV (MIMIC-IV), including demographic data, acute physiology score (APS), comorbidities, vital signs, laboratory indicators, treatment status, ICU length of stay, and outcome indicators. The main outcome measure is ICU mortality. AKI patients were divided into Alb infusion group and Alb non infusion group based on whether they received Alb treatment. Multiple imputation was used to process missing data and eliminate variables that missing more than 30%. To ensure the stability of the results, propensity score matching (PSM) and inverse probability weighting (IPW) were used to correct the results. Using Kaplan-Meier survival curve and Cox proportional hazards regression model to evaluate the effect of Alb infusion on ICU survival rate in AKI patients. Perform subgroup analysis based on patient age, gender, and comorbidities to evaluate the prognostic effects of Alb on different patient subgroups. RESULTS: A total of 6 390 AKI patients were included, including 1 721 in the Alb infusion group and 4 669 in the Alb non infusion group. After adjusting for key covariates in the Cox regression model, compared with the Alb non infusion group, patients in the Alb infusion group were significantly younger in age, with APS III score, proportion of vasoactive drugs and continuous renal replacement therapy (CRRT) use, sepsis proportion, heart rate, respiratory frequency, aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine (Cr), lactic acid (Lac), and arterial partial pressure of carbon dioxide (PaCO₂) levels significantly higher. The proportion of hypertension, myocardial infarction, and congestive heart failure, as well as blood pressure, urine output, platelet count (PLT), and Alb levels were significantly lower. The results of univariate and multivariate Cox regression analysis on the raw data showed that the risk of death in the Alb infusion group was significantly lower than that in the Alb non infusion group [hazard ratio (HR) = 0.69, 95% confidence interval (95%CI) was 0.60-0.80, all P < 0.05]. The results after propensity score matching (PSM) and inverse probability weighting (IPW) processing are consistent with the original data trend (both P < 0.05). The Kaplan-Meier survival curve showed that the cumulative survival rate during ICU stay in the Alb infusion group was significantly higher than that in the Alb non infusion group (24.48% vs. 12.17%, Log-Rank test: χ² = 74.26, P < 0.05). Subgroup analysis shows that Alb infusion has a more significant survival benefit for AKI patients who use vasoactive drugs, have concurrent sepsis, and do not have liver disease. CONCLUSION Albumin infusion can decrease the ICU mortality of AKI patients.

Objective:To investigate the effect of heat shock protein 60 (HSP60) overexpression on the ability of bone marrow mesenchymal stem cells (MSCs) and its therapeutic effect on rats with phosgene induced acute lung injury.Methods:HSP60 was transfected into MSCs by adenovirus. Western blot was used to measure the expressions of HSP60 before and after transfection. CCK-8 assay was used to detect the activity of MSCs, flow cytometry was used to detect the apoptotic ability of MSCs, and Transwell assay was used to observe the migration ability of MSCs. Sixty SPF grade male SD rats were randomly divided into control group, phosgene exposure group (inhalation of phosgene for 5 min) , MSCs group (phosgene exposure, MSCs treatment group) and transfected MSCs group (phosgene exposure, overexpression of HSP60 MSCs treatment group) . The pathological changes of lung were observed by lung pathological section, lung wet dry ratio, the degree of pulmonary edema, the total cell count and total protein content of alveolar lavage fluid, the inflammatory changes of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in BALF and serum were observed. The data were analyzed by Graphpad Prism 8.0 software. Paired comparisons were performed by non paired t-test. One way ANOVA was used for comparison between groups. Results:The proliferation ability of MSCs transfected with HSP60[ A= (0.69±0.05) ] was significantly higher than that of MSCs not transfected with HSP60[ A= (0.27±0.02) ] ( P<0.05) . Compared with the phosgene exposure group, the pulmonary edema and inflammatory factor infiltration of MSCs group and MSCs transfected group were reduced. However, compared with MSCs group, the degree of pulmonary edema in MSCs transfected group was significantly improved, the levels of inflammatory factors IL-6 and TNF-α were significantly decreased, and the total protein content and total cell count in bronchoalveolar lavage fluid were less ( P<0.05) . Conclusion:MSCs transfected with HSP60 can enhance the ability of proliferation, anti apoptosis, migration and the curative effect in rats with phosgene induced acute lung injury.

Objective To probe into the role of nursing classification and marking management in ICU nursing management. Methods According to the admission date,the first 87 patients hospitalized in our department were assigned into the control group and another 84 into the intervention group.Then the human resources were divided based on the ABCD nursing classification and marking management for ICU.The two groups were compared in terms of adverse events.Results The incidences of pressure sores, non-planned extubation,improper clinostatism for using respirator,hypoglucycaemia during reinforced treatment with insulin, respirator-associated pulmonary pneumonia,tube-associated infection,and multidrug resistant bacteria in the intervention group were all significantly lower than those in the control group (allP<0.05).Conclusion The nursing classification and marking management for ICU nursing management can enhance the nursing quality.

Objective To observe the effect of intelligent trunk intensive training on motor and balance for patients with stroke. Methods 80 stroke patients were divided into treatment group (n=40) and control group (n=40) randomly. Both groups accepted routine rehabilitation,and the treatment group accepted intelligence trunk intensive training in addition for 6 weeks. They were assessed with Rivermead Movement Index (RMI), the Berg Balance Scale (BBS), Sheikh trunk control ability evaluation before and after treatment. Results All the scores improved after treatment in both groups (P<0.001), and improved more in the treatment group than in the control group (P<0.001).The score of trunk control positively correlated with the score of RMI and BBS respectively (r=0.576, r=0.592, P<0.05). Conclusion Intelligent trunk intensive training can further improve the motor and balance of patients with stroke.
