Objective To investigate the effect oflevecamitine on nutrition,microinflammation status in ma-intenance hemodialysis (MHD) patients. Methods Forty two MHD patients were selected, who had undergone he-modialysis for at least two months before the study. One gram of levoeamitine was injecfed to the patients at the end of each dialysis treatment for six months. The parameters of inflammation stress were studied. Results After treatment with levocarnitine for six months, the average levels of dry body weight decreased markedly. ( P<0.05 ), The aver-age serum levels of C2reaetive protein (CRP),interleuldn26 (IL26) ,tumor necrosis factor2α(TNF2α), (P<0.01 ). Difference was not significant between serum lipid parameters before and after the treatment. Conclusion Intravenous supplement with levocamitine in MHD patients, appears to be associated with an improvement of nutrition and mieroinflammation status.

Objective: To investigate the clinical effect of plasma exchange (PE) versus double plasma molecular adsorption system combined with PE (DPMAS+PE) in the treatment of toxic hepatic failure. Methods: A total of 67 patients with toxic hepatic failure who were admitted during the same period of time were divided into PE group, DPMAS+ PE group, and control group. The 22 patients in the PE group were treated with PE alone, and the 24 patients in the DPMAS+PE group were given DPMAS combined with PE. The clinical out-come was compared between the three groups. Results: Both treatment groups had significantly higher clinical response rate and 24-week survival rate than the control group. After treatment, both treatment groups had significant reductions in the serum levels of total bilirubin (TBil) , direct bilirubin (DBil) , alanine aminotransfer-ase (ALT) , and aspartate aminotransferase (AST) , and the PE group had significant reductions in the albumin (Alb) level and activated partial thromboplastin time (APTT) (P<0.05) ; the DPMAS+PE group showed no sig-nificant changes in the Alb level and APTT (P>0.05). There were no significant differences in TBil, DBil, ALT, and AST between the two treatment groups after treatment (P>0.05). After treatment, the PE group had significantly higher Alb level and APTT than the DPMAS + PE group (P<0.05). Compared with the control group, both treatment groups had significant reductions in TBil, DBil, ALT and AST after treatment (P<0.05). Conclusion The two artificial liver support techniques can significantly improve patients' liver function and in-crease their survival rate, and the combined artificial liver support technique can reduce the amount of plasma used.
