Objective To observe the effect of Yiqi Gushen Liquid（qi-boosting kidney-securing liquid） on flammation state in maintenance hemodialysis patients.Methods Seventy-two maintenance hemodialysis patients were randomized into treatment group（37 cases） and controlled group（35 cases）.Bicarbonate dialysis was given to both groups 8 to 12 hours weekly and Yiqi Gushen Liquid（40ml/L） was added in the treatment group.The treatment course lasted for 6 months.The malnutrition-inflammation score（MIS） was observed before and after treatment.Results After treatment

the MIS score of dietary intake

gastrointestinal symptoms

the arm muscle circumference

skinfold thickness in the arm muscle

serum albumin

transferrin and total score improved significantly in the treatment group（P<0.05）.There was no significant difference in MIS between groups and in the control group as compared with before and after treatment（P>0.05）.Conclusion Yiqi Gushen Liquid could reduce the MIS and improve the prognosis for maintenance hemodialysis patients.
