Objective To investigate the underlying molecular mechanisms of brain injury in rats after cardiac arrest and cardiopulmonary resuscitation (CPR) by observing necroptosis of brain cells and changes of 90 cytokines in brain tissue. Methods Sprague-Dawley (SD) rats were divided into Sham group (n = 10) and cardiac arrest group (n = 10) according to random number table method. The model of asphyxia cardiac arrest for 6 minutes followed by CPR model was established. Tracheal intubation in Sham rats were routinely performed without inducing cardiac arrest. Neurological deficit score (NDS) was evaluated, blood samples were collected and rats were sacrificed, then serum S100B level was measured by enzyme linked immunosorbent assay (ELISA) on the third day after CPR. Necroptotic cells in brain were detected by immunofluorescence staining. The levels of 90 cytokines expression in brain were measured by antibody array. The relative ratio of the two groups of protein expression ≥ 1.5 or ≤ 0.5 and P less then 0.05 repr nerve cells.Objective To observe the value of heart-type fatty acid-binding protein (H-FABP) and echocardiographic indexes in the diagnosis of cardiac insufficiency in sepsis. Methods A prospective observational study was conducted. Eighty patients with sepsis admitted to the department of critical care medicine of the First Affiliated Hospital of Medical College of Shihezi University from October 2016 to January 2018 were enrolled. General clinical data such as gender, age, acute physiology and chronic health evaluation II (APACHE II), sequential organ failure assessment (SOFA) score, hospitalization time and 28-day mortality were recorded. Echocardiographic indexes at 1, 3, 7, 10 days after diagnosis, and white blood cell (WBC), neutrophilic granulocyte percentage (N%), N-terminal pro-brain natriuretic peptide (NT-proBNP), serum H-FABP level were recorded. Sepsis patients were divided into normal cardiac function group (n = 30) and cardiac insufficiency group (n = 50) according to cardiac function, the differences of eas 0.738, 93.37%, 56.77%; H-FABP was 0.673, 80.26%, 57.25%, respectively. H-FABP was tested in parallel with LVEDV, SV, LVEF, CO, LVFS, EPSS, IVRT, A', Sm, and the positive predictive values were higher than the single diagnostic test (85.45%, 93.91%, 96.72%, 94.74%, 89.43%, 98.00%, 92.00%, 99.42%, 93.60%, respectively), the negative predictive values were lower than the single diagnostic test (50.89%, 57.93%, 49.15%, 58.18%, 57.05%, 45.74%, 57.92%, 64.13%, 47.78%, respectively). Conclusions Cardiac ultrasound indicators LVEDV, SV, LVEF, CO, LVFS, EPSS, IVRT, A', and Sm combined with H-FABP are of certain value in the diagnosis of sepsis-associated heart dysfunction.Objective To explore a better indicator that can predict septic shock induced acute kidney injury (AKI) by combining renal resistive index (RRI) and central venous pressure (CVP). Methods A prospective observational study was conducted. Patients with septic shock admitted to department of critical care medicine of Hebei General Hospital from November 2017 to October 2018 were enrolled. Baseline characteristics such as age, gender, underlying diseases, infection sites, acute physiology and chronic health evaluation II (APACHE II) in the first 24-hour, sequential organ failure assessment (SOFA) were recorded; Doppler-based RRI was obtained on the first day when hemodynamics was relatively stable, meanwhile the dose of norepinephrine and hemodynamic parameters were assessed. Urine output per hour, the total duration of mechanical ventilation, the length of intensive care unit (ICU) stay and 28-day mortality were also collected. Observational end point was death at discharge or the 28th day after ICU admission, wnce interval (95%CI) was 1.03-1.40, P = 0.022; RRI OR = 3.02, 95%CI was 2.64-3.48, P = 0.006; Lac OR = 2.43, 95%CI was 1.32-4.50, P = 0.005; PCT OR = 1.20, 95%CI was 1.05-1.38, P = 0.009]. ROC curve analysis showed that the area under ROC curve (AUC) values of CVP ≥ 9.5 mmHg (1 mmHg = 0.133 kPa) and RRI ≥ 0.695 for predicting septic shock induced AKI were 0.656 and 0.662 respectively. The AUC value of the combination of RRI and CVP was greater compared with either RRI or CVP alone in predicting septic shock induced AKI, which AUC value was 0.712, 95%CI was 0.615-0.809, the sensitivity was 59% and the specificity was 75%. Conclusions High CVP and RRI were independent risk factors for septic shock induced AKI. The combination of RRI and CVP performs poorly in predicting septic shock induced AKI. Further studies are needed to describe factors influencing Doppler-based assessment of RRI, which may help clinicians to prevent AKI early.Objective To observe the changes of renal function in critically ill patients using vancomycin and analyze the renal protective effect of high dose vitamin C (VC) on vancomycin nephrotoxicity. Methods Retrospective analysis was carried out to enroll the patients who were hospitalized in emergency intensive care unit (ICU) of Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2012 to October 2019. All patients were administered with vancomycin or VC infusion in addition. According to the infusion of vancomycin alone or in combination with VC, the patients were divided into vancomycin group and vancomycin in combination with VC group; vancomycin group was further divided into two groups according to before vancomycin or after vancomycin usage; combination group were further divided into two groups according to before VC use or after VC. https://www.selleckchem.com/products/zanubrutini-bgb-3111.html The initial dosage of vancomycin was calculated according to the actual weight of the patient and adjusted according to the renal functimycin is high. Intravenous high dose VC can significantly reduce the nephrotoxicity of vancomycin and shorten the length of hospital stay. When vancomycin is used in critically ill patients, VC can be used in combination to reduce or avoid drug-induced renal injury, improve curative effect and reduce toxic effects.Objective To investigate the diagnostic and diagnostic values of plasma microRNA-21-3p (miR-21-3p) and miR-551-5p expression in patients with acute pancreatitis (AP). Methods A prospective observational study was conducted. AP patients admitted to the Third People's Hospital of Hainan Province from January 1st 2017 to December 31st 2019 were enrolled. The patients were divided into mild acute pancreatitis (MAP) group, moderate severe acute pancreatitis (MSAP) group and severe acute pancreatitis (SAP) group according to their severity. Fasting venous blood was collected from all subjects the day after admission, and real-time quantitative polymerase chain reaction (PCR) as used to detect the expression levels of plasma miR-21-3p and miR-551-5p. Rehabilitation, discharge or death were end points of study. In addition, 50 healthy people in the same period were selected as the control group. The receiver operating characteristic (ROC) curve was used to analyze the value of the expression levels of plasma miR-21-3p and miR-551-5p for the diagnosis and prognosis of SAP.
