ABSTRACT
Objective To investigate the correlation between red cell volume distribution width (RDW) and the mortality rate of acute respiratory distress syndrome (ARDS) patients after renal transplantation. Methods Clinical data of 106 ARDS patients undergoing renal transplantation were retrospectively analyzed. According to RDW, all patients were assigned into the normal (≤15.0%, n=68) and increasing RDW groups (>15.0%, n=38). Baseline data and the incidence of adverse events were statistically compared between two groups. Kaplan-Meier survival curve was adopted to compare the 50 d-mortality rate between two groups. Cox's proportional hazards regression model was utilized to identify the risk factors of the mortality of ARDS patients. Results Among 106 patients, the 50 d-mortality rate was calculated as 43.4% (46/106). The sequential organ failure assessment (SOFA) score, serum creatinine, hemoglobin and platelet count significantly differed between two groups (all P<0.05). In the increasing RDW group, the 50 d-mortality rate and the incidence of infectious shock were significantly higher than those in the normal RDW group (both P<0.05). Kaplan-Meier survival curve demonstrated that the 50 d-mortality rate significantly differed between two groups (P<0.01). Cox's proportional hazards regression model univariate analysis revealed that hemoglobin level<100 g/L, serum creatinine>133 μmol/L, platelet count<100×109/L, severe ARDS and RDW>15.0% were the potential risk factors of the 50 d-mortality rate in ARDS patients (all P<0.05). Multivariate analysis demonstrated that severe ARDS [odd ratio (OR)=12.77, 95%confidence interval (CI) 11.63-15.39, P<0.001] and RDW>15.0% (OR=2.01, 95%CI 1.02-3.94, P<0.043) were the independent risk factors of the 50 d-mortality rate in ARDS patients. Conclusions RDW elevation is correlated with the severity of disease and 50 d-mortality rate in ARDS patients following renal transplantation. RDW can serve as a clinical parameter to predict the prognosis of ARDS patients after renal transplantation.
ABSTRACT
Objective To investigate the effect of daptomycin on the serum levels of proclacitonin (PCT) and copeptin in septicopyemia patients induced by methicillin-resistant Staphylococcus aureus (MRSA). Methods 54 cases septicopyemia patients induced by MRSA were selected and divided into two groups, 27 cases in each group. The two groups received fluid replacement therapy and nutrition support, the control group received vancomycin (0.5g per times, three times daily) with intravenous drip, and the study group received daptomycin (6mg/kg, once daily) with intravenous drip. The serum PCT, proclacitonin levels pre-and post-treatment in two groups were detected, the acute physiology and chronic health evaluationⅡ (APACHEⅡ) and sepsis-related organ failure assessment (SOFA) were used to evaluate the patients' condition, the clearance time of pathogenic bacteria was recorded and the clinical efficacy was compared between two groups. Results Compared with before treatment, serum PCT, C-reactive protein (CRP), interleukin-1β(IL-1β) and IL-6 in two groups decreased(P<0.01), the count of WBC, NE% and copeptin decreased (P<0.01), the APACHEⅡ and SOFA score were lower(P<0.05); compared with the control group, the PCT, CRP, IL-1 beta and IL-6 in study group were lower(P<0.05), the count of WBC, NE% and copeptin level were lower(P<0.05), APACHEⅡ and SOFA score were lower(P<0.05), the pathogen clearance rate was higher(P<0.05), clearance time was shorter(P<0.05), the total efficiency was higher(P<0.05). Conclusion Daptomycin can reduce serum PCT and copeptin in patients with septicopyemia induced by MRSA, and remove pathogenic bacteria rapidly, inhibit the inflammatory reaction, safe and reliable.

ABSTRACT
Objective: To observe the protective effect of fasudil hydrochloride against acute renal injury in septicopyemia rats. Methods: A total of 60 Wister rats were included in the study and divided into control group (n = 10), model group (n = 25) and treatment group (n = 25). Model group and treatment group received intraperitoneal injection of endotoxin (ET) to establish acute renal injury models while the control group only received daily intraperitoneal injection of normal saline 1 mL. Five rats were taken out of model group and treatment group respectively at 1 h (T1), 6 h (T2), 12 h (T3), 24 h (T4) and 48 h (T5), for intraperitoneal injection of ET 30 mg/kg. Treatment group received intraperitoneal injection of fasudil hydrochloride 30 mg/kg 1 h before injection of ET. For three groups, 5 mL blood samples were collected from postcava for determination of serum creatinine and urea nitrogen levels at different time points. Concentrations of serum tumor necrosis factor α and ET-1 were determined by using ELISA. The renal pathologic changes were observed under the microscope. Results: Serum creatinine levels in both model group and treatment group were significantly higher than control group at T2-T5 (P < 0.05) while the levels in treatment group were significantly lower than control group at T3-T5 (P < 0.05). At T2-T5, blood urea nitrogen levels in model group and treatment group were significantly higher than control group (P < 0.05) while the levels in treatment group were significantly lower than model group at T3-T5 (P < 0.05). Concentrations of serum tumor necrosis factor α in model group and treatment group were significantly higher than control group at T1-T5 (P < 0.05) while the levels in treatment group were significantly lower than model group at T1-T5 (P < 0.05). Serum ET-1 concentrations in model group and treatment group were significantly higher than control group at T1-T5 (P < 0.05) while the levels in treatment group at T1-T4 were significantly lower than model group (P < 0.05). Rats in control group showed no swelling or hyperemia in kidney cells but normal structure and normally arranged renal tubular epithelial cells. Obvious injury was observed in model group at T3 and renal tubular epithelial cells in disorder and at swelling condition, hyperemia and angiectasis in glomerulus, degenerative opacities and vacuolar degeneration, and maximized injury were observed at T4. Injury in renal tissue in treatment group was significantly milder than model group. Conclusions: Fasudil hydrochloride has the significantly protective effect against acute renal injury in septicopyemia rats.
