Objective To explore the effect of rythropoietin ( EPO) on the proliferation of high glucose -cultured human kidney mesangial cells ( MCs) and its expression levels of cytokines and inflammatory factors and investigate the biological effects of EPO on renal tissue.Methods From December 2014 to May 2015, obtained MCs and employed random number table method to divide them into eight groups: blank control group , high glucose induction group , mannitol control group , EPO control group , 5 U/ml EPO intervention group , 10 U/ml EPO intervention group , 20 U/ml EPO intervention group and Rho kinase inhibitor group.The mRNA levels of RhoA and ROCK 1 were determined by RT-PCR; connective tissue growth factor ( CTGF) , Collagen Ⅳ、 Interleukin -6 ( IL-6 ) and tumor necrosis factor -α( TNF -α) were detected by ELISA;absorbance value (OD value) of cell proliferation was measured by CCK -8.Results High glucose induction group was higher ( P<0.05 ) than blank control group in the mRNA expression levels of RhoA and ROCK 1;5 U/ml EPO intervention group , 10 U/ml EPO intervention group and 20 U/ml EPO intervention group were lower (P<0.05) than glucose induction group in the mRNA expression levels of RhoA and ROCK 1; the pairwise comparison among 5 U/ml EPO intervention group , 10 U/ml EPO intervention group and 20 U/ml EPO intervention group showed significant differences ( P<0.05) in the mRNA expression levels of RhoA and ROCK1;Rho kinase inhibitor group was higher (P<0.05) than 5 U/ml EPO intervention group, 10 U/ml EPO intervention group and 20 U/ml EPO intervention group in the mRNA expression levels of RhoA and lower in the mRNA expression levels of ROCK 1.The mRNA expression level of RhoA was positively correlated with that of ROCK 1 in high glucose induction group , 5 U/ml EPO intervention group , 10 U/ml EPO intervention group and 20 U/ml EPO intervention group ( r=0.829, 0.898, 0.831, 0.861;P<0.05) .High glucose group was higher (P <0.05) than blank control group in the levels of CTGF and Collagen Ⅳat 24 h and the levels of IL-6 and TNF-αat 24 h and 48 h;5 U/ml EPO intervention group , 10 U/ml EPO intervention group , 20 U/ml EPO intervention group and Rho kinase inhibitor group were higher ( P<0.05) than blank control group and were lower than high glucose induction group in the levels of CTGF and Collagen Ⅳat 24 h and the levels of IL-6 and TNF-αat 24 h and 48 h;10 U/ml EPO intervention group , 20 U/ml EPO intervention group and Rho kinase inhibitor group were lower (P<0.05) than 5 U/ml EPO intervention group in the levels of CTGF and Collagen Ⅳat 24 h and the levels of IL-6 and TNF-αat 24 h and 48 h;20 U/ml EPO intervention group and Rho kinase inhibitor group were lower ( P<0.05) than 10 U/ml EPO intervention group in the levels of CTGF and Collagen Ⅳat 24 h and the levels of IL-6 and TNF-αat 24 h and 48 h.At 24 h, 48 h and 72 h, high glucose induction group , EPO control group , 5 U/ml EPO intervention group , 10 U/ml EPO intervention group and 20 U/ml EPO intervention group were higher (P<0.05) than blank control group in the OD value of MCs proliferation , and Rho kinase inhibitor group was lower ( P<0.05 ) than high glucose induction group in the OD value of MCs proliferation;the pairwise comparison among 5 U/ml EPO intervention group , 10 U/ml EPO intervention group and 20 U/ml EPO intervention group showed significant differences in the OD value of MCs proliferation ( P<0.05);in each of the three groups, the pairwise comparison of OD value of MCs proliferation among 24 h, 48 h and 72 h showed significant differences ( P<0.05) .Conclusion High glucose can inhibit the proliferation of MCs;high glucose can increase the expression of CTGF , Collagen Ⅳ, IL-6 and TNF-α, and EPO can inhibit the expression of CTGF , Collagen Ⅳ, IL-6 and TNF-αin MCs cultured by high glucose in certain concentration range and time range , facilitate proliferation and protect kidney.The mechanism may be related with the signal transduction pathway of RhoA /ROCK.
