Expression and significance of adiponectin in serum and placenta tissue in preeclampsia pregnancy women / 中国医师进修杂志

ABSTRACT

Objective To analyze the expression and significance of adiponectin in serum and placenta tissue in preeclampsia pregnancy women.Methods Serum adiponectin levels were measured by Enzyme-linked immuno sorbent assay (ELISA) in 52 cases of normal pregnant women (control group),58 cases of mild preeclampsia pregnancy women (mild preeclampsia group),and 55 cases of severe preeclampsia pregnancy women (severe preeclampsia group).Insulin resistance was estimated using the homeostatic model assessment-insulin resistance index (HOMA-IR).The expression of adiponectin in placenta tissue was detected by immunohistochemical SP methods in three groups.Results Fasting glucose level in severe preeclampsia group was higher than that in control group and mild preeclampsia group [(5.56 ± 1.37) mmol/L vs.(4.55 ± 0.51),(4.68 ± 0.66) mmol/L],fasting insulin level and HOMA-IR in mild preeclampsia group and severe preeclampsia group were higher than those in control group [(14.19 ±3.42),(14.90 ±6.64) mU/L vs.(9.87 ± 1.75) mU/L,1.04 ±0.37,1.18 ±0.56 vs.0.67 ±0.21],serum adiponectin level in severe preeclampsia group was higher than that in control group and mild preeclampsia group [(15.79 ± 4.86) mg/L vs.(11.47 ±3.50),(11.92 ± 2.96) mg/L],the differences were statistical significance (P ＜ 0.05).There was no difference of adiponectin expression levels in placenta tissue among three groups (P ＞0.05).There was no significant correlations between serum adiponectin level and HOMA-IR,expression levels of adiponectin in placenta tissue(P ＞ 0.05).Conclusions Serum adiponectin levels and HOMA-IR are higher in the severe preeclampsia pregnancy women.Increased serum adiponectin levels may be an appropriate feedback regulation in preeclampsia pregnancy women.
