Abstract:
Objective:To observe the effects of wear particles from joint prosthesis on the expression of macrophage migration inhibiting factors(MMIF).Methods:Suspension with titanium particles was prepared and mice macrophages were cultured.The following experimentations were respectively carried on the third generation of mice macrophages.①The cells were divided into 4 groups,cells in group A were added with nothing,while cells in group B,C and D were added with titanium particles suspension(0.01%,0.05% and 0.1%,respectively).The contents of MMIF protein and MMIF mRNA of the 4 groups were respectively detected through enzyme linked immunosorbent assay(ELISA)and polymerase chain reaction(PCR)after culturing for 24 hrs.②The cells were divided into 2 groups,cells in control group were added with nothing,while cells in observation group were added with 0.1% titanium particles suspension.The contents of MMIF protein and MMIF mRNA of the 2 groups were respectively detected through ELISA and PCR at 0,6,12,24 and 36 hrs from the beginning of the experimentation.③The cells were divided into 4 groups,cells in groupⅠwere added with nothing,and cells in groupⅡwere added with 0.1% titanium particles suspension and groupⅢwere added with pyrrolidine dithiocarbamate(PDTC)(100 μmol/ml),while cells in groupⅣwere firstly added with PDTC(100 μmol/ml)and titanium particles suspension(0.1%)one hr later.The contents of MMIF protein of the 4 groups were detected through ELISA after culturing for 24 hrs.④The cells were divided into 2 groups,cells in group a were added with nothing,while cells in group b were added with 0.1% titanium particles suspension.The contents of phosphorylation p65 of the 2 groups were respectively detected through ELISA at 0,0.5,1,3 and 6 hrs from the beginning of the experimentation.Results:①Effect of titanium particles suspension concentration on MMIF expression:There were statistical differences in the contents of MMIF protein and MMIF mRNA of macrophages among the 4 groups(F=207.158,P=0.000; F=64.955,P=0.000).There were no statistical differences in the contents of MMIF protein and MMIF mRNA between group A((3.93±0.11)ng/ml,(0.03±0.01))and group B((4.21±0.27)ng/ml,(0.10±0.01)(P=0.167; P=0.223); the contents of MMIF protein and MMIF mRNA of group A were lower than those of group C((6.56±0.27)ng/ml,(0.25±0.09))and there were statistical differences(P=0.000; P=0.004); the contents of MMIF protein and MMIF mRNA of group A were lower than those of group D((7.82±0.21)ng/ml,(0.70±0.09)),and there were statistical differences(P=0.000; P=0.000); the contents of MMIF protein and MMIF mRNA of group B were lower than those of group C(P=0.000; P=0.025)and group D(P=0.000; P=0.000); the contents of MMIF protein and MMIF mRNA of group C were lower than those of group D(P=0.000; P=0.000).②Effect of titanium particles stimulation time on MMIF expression:There were no statistical differences in the contents of MMIF protein and MMIF mRNA of control group among different time points(F=0.310,P=0.865; F=0.065,P=0.991).There were statistical differences in the contents of MMIF protein and MMIF mRNA of observation group among different time points(F=32.857,P=0.000; F=15.621,P=0.000).Further comparison between any two time points showed that there were no statistical differences in the contents of MMIF protein and MMIF mRNA between 6 hrs((4.14±0.24)ng/ml,(0.08±0.04))and 0 hr((3.60±0.40)ng/ml,(0.03±0.01))(P=0.133,P=0.621); the contents of MMIF protein and MMIF mRNA at 12 hrs((5.61±0.47)ng/ml,(0.36±0.21))were larger than those at 0 hr,and there were statistical differences(P=0.000; P=0.004); the contents of MMIF protein and MMIF mRNA at 24 hrs((7.15±0.10)ng/ml,(0.71±0.12))were larger than those at 12 hrs,and there were statistical differences(P=0.000; P=0.003); the contents of MMIF protein and MMIF mRNA at 36 hrs((5.22±0.85)ng/ml,(0.31±0.18))were lower than those at 24 hrs(P=0.000; P=0.004)and larger than those at 0 hr(P=0.000; P=0.003).③Effect of titanium particles and PDTC on the expression of MMIF protein:After experimentations,the MMIF protein contents were(3.77±0.42)ng/ml(groupⅠ),(7.59±0.28)ng/ml(groupⅡ),(4.23±0.42)ng/ml(groupⅢ)and(6.48±0.5)ng/ml(groupⅣ),respectively.The results of analysis of variance of factorial design showed that single use of 0.1% titanium particles suspension could promote the expression of MMIF protein(F=153.363,P=0.000),while single use of PDTC(100 μmol/ml)had no influence on the expression of MMIF protein(F=1.762,P=0.221).PDTC(100 μmol/ml)could depress the promotive effect of 0.1% titanium particles suspension on expression of MMIF protein(F=10.325,P=0.012).④Effect of titanium particles suspension concentration on NF-κB signal pathway in macrophages:There were no statistical differences in phosphorylation p65 contents among different time points in group a(F=0.248,P=0.904).There were statistical differences in phosphorylation p65 contents among different time points in group b(F=30.217,P=0.000).Further comparison showed that phosphorylation p65 contents at 0.5 hr((17.68±0.55)pg/mg)was higher than that at 0 hr((10.38±3.18)pg/mg)(P=0.005); phosphorylation p65 contents at 1 hr((23.31±2.05)pg/mg)was higher than that at 0.5 hr(P=0.020); phosphorylation p65 contents at 3 hrs((31.80±1.84)pg/mg)was higher than that at 1 hr(P=0.002); phosphorylation p65 contents at 6 hrs((18.42±3.61)pg/mg)was lower than that at 3 hrs(P=0.000)and larger than that at 0 hr(P=0.003).Conclusion:Wear particles from joint prosthesis can up-regulate the expression of MMIF through NF-κB signal pathway and promote inflammatory reactions around prosthesis,which leads to bone absorption and osteolysis,and leads to aseptic prosthesis loosening as a further result.
