Objective:To screen,identify,and compare the serum biomarkers between anovulatory dysfunctional uterine bleeding(ADUB)and ovulatory dysfunctional uterine bleeding(ODUB)in Lizu females.Methods:The subjects included 128 ADLB patients,63 ODUB patients,and 93controls.The serum and supernate of the subjects’mense were collected and stored at-80°C until use.Differential proteins in the sera of three groups were screened using surface-enhaneed laser desorption ionization time-of-flight mass spectrometry.The screened proteins were then identified by tricine-SDS-PAGE gel and spectrometry.Protein expression levels in the menses of ADUB,ODUB,and control subjects were determined using ELISA,RT-PCR,and Western blotting.SPSS 14.1 was used for statistical analysis and chart drawing(a=0.05),Results:Three differentia)protein peaks with peak values of 11.80,13.59,and 14.68 km/z were,screened and identified as serum amyploid protein A(SAA),vascular endothelial growth factor,and vitamin K epoxide reductase,respectively.The SAA was highly expressed in the menses of ADUB and ODUB patients but poorly expressed in the controls.The vascular endothelial growth factor was highly expressed in the menses of ODUB and controls but poorly expressed in ADUB patients.Meanwhile,the vitamin K epoxide reductase was highly expressed in the menses of ADUB and control subjects but poorly expressed in ODUB patients.Conclusions:The SAA is the common serum biomarker of ADUB and ODUB.ADUB may be related to angiogenesis impairment,whereas ODUB may be associated with blood coagulation disruption.

The SAA was highly expressed in the menses of ADUB and ODUB patients but poorly expressed in the controls. vascular endothelial growth factor was highly expressed in the menses of ODUB and controls but poorly expressed in ADUB patients. Meanwhile while the vitamin K epoxide reductase was highly expressed in the menses of ADUB and control subjects but poorly expressed in ODUB patients. Conclusions: The SAA is the common serum biomarker of ADUB and ODUB. ADUB may be related to angiogenesis impairment, and ODUB may be associated with blood coagulation disruption.
