Objective To evaluate the diagnostic value of serum albumin (Alb),total protein (TP),body mass index (BMI),Mini Nutritional Assessment (MNA) and hand strength in the nutritional status in maintenance hemodialysis (MHD) patients.Methods A total of 126 MHD patients were included in this study who had been on MHD for at least 3 months.Depending on the levels of Alb,patients were divided into two groups:normal nutrition group (group A) and malnutrition group (group B).TP,BMI,MNA and hand strength were also detected at the same time.Independent samples t test,Spearman correlation analysis,ROC curve were used to analyze their difference between the two groups and evaluate their diagnostic value in nutritional status in MHD patients.Results Age,sex,height,weight and dialysis ages had no statistical significant difference (P ＞ 0.05) between group A and group B,while Alb,TP,BMI,MNA and hand strength had statistical significant difference (P ＜ 0.05) between two groups.After adjusting for age,sex and hemodialysis age,Alb,TP,BMI,MNA and hand strength were positively correlated with each other (P ＜ 0.05).Since the area under the ROC curve of BMI was the smallest,BMI had the lowest diagnostic value in evaluation of the nutritional status in those patients.Conclusions Alb,TP,MNA and hand strength are good indexes in evaluation of the nutritional status in MHD patients but BMI is not.

Objective:To evaluate the effect of ulinastatin on hyperoxia-induced acute lung injury (ALI) and its relationship with Wnt/β-catenin signaling pathway in infantile rats.Methods:A total of 36 clean-grade Sprague-Dawley rats, aged 14 days, weighing 40-50 g, were divided into 3 groups ( n=12 each): control group (C group), hyperoxia-induced ALI group (ALI group) and ulinastatin group (UTI group). Hyperoxia-induced ALI was induced by inhaling oxygen at concentration greater than 90% for 72 h. At 1 day after the model was established successfully, ulinastatin 50 000 U/kg was injected intraperitoneally daily at the same time for 3 consecutive days in group UTI, while the equal volume of normal saline was injected intraperitoneally at the same time point in C and ALI groups.The animals were sacrificed at 4 days after the model was established successfully, the lung tissues were taken for determination of the wet/dry weight ratio (W/D ratio), for microscopic examination of the pathological changes which were scored, for measurement of interleukin-6 (IL-6) IL-1β and tumor necrosis factor-alpha (TNF-α) (by enzyme-linked immunosorbent assay) and for detection of the expression of phosphorylated glycogen synthase kinase (p-GSK-3β), Wnt3a and β-catenin by Western blot, and ultrastructure was examined with with an electron microscope. Results:Compared with C group, W/D ratio and lung injury score were significantly increased, the contents of IL-6, IL-1β and TNF-α were increased, and the expression of p-GSK-3β, Wnt3a and β-catenin were up-regulated in lung tissues in group ALI ( P<0.05). Compared with group ALI, W/D ratio and lung injury score were significantly decreased, the contents of IL-6, IL-1β and TNF-α were decreased, and the expression of p-GSK-3β, Wnt3a and β-catenin were down-regulated in lung tissues in group UTI ( P<0.05). The ultrastructure injury in group UTI was reduced as compared with group ALI. Conclusion:The mechanism by which ulinastatin can alleviate hyperoxia-induced ALI is related to inhibiting the activation of Wnt/β-catenin signaling pathway and decreasing inflammatory response in infantile rats.
