Objective To investigate the effects of piperazine ferulate tablets combined with Huangqi injection on β2-microglobulin,NGAL and clinical efficacy in patients with acute renal failure.Methods A total of 56 patients with acute renal failure from June 2012 to October 2015 in our hospital were collected and randomly divided into the experimental group and the control group with 28 cases in each group.All patients before the treatment of conventional care,diuretics and vasodilators to increase the patient's serum protein and vitamins,so that patients with the body's pH,moisture and electrolyte balance,and gave hemodialysis and low molecular heparin anticoagulant therapy.Patients in the control group were treated on the base of the conventional therapy withastragalus injection 20mL/time,one time a day,intravenous drip,treatment of four weeks; patients in the experimental group were treated on the base of the control group with piperazine ferulate tablet 200mg/time,three times/day,treatment of four weeks.After treatment,compared patients' β2 microsphere protein,NGAL and KIM-1 levels.Results There was no significant difference in the survival rate between the two groups.Compared with before treatment,β2 microsphere protein,NGAL and KIM-1 levels in two groups were lower(P<0.05);Compared with control group,β2 microsphere protein,NGAL and KIM-1 levels in the experimental group were lower(P<0.05).Conclusion Piperazine ferulate tablets combine with astragalus injection in the treatment of patients with acute renal failure have a better clinical curative effect,speculate that the mechanism is relate to reduce β2 microsphere protein,NGAL and KIM-1 levels.

AIM and METHODS: Chemotactic migration of peripheral blood mononuclear cell(PBMNC) of healthy blood donors(BD) and patients with blood stasis syndrome(BSS) across polycarbonate membrane(PCM) and human umbilical vein endothelial cell(HUVEC) monolayer, IL-8 produced by migrat PBMNC and effects of protocatechuic aldehyde(PCA) on the process mentioned above were investigated. RESULTS: 1) The numbers of migrating PBMNC in group BSS was higher than that in group BD(P
