Objective To detect the levels of plasma gelsolin(GSN),vitamin D binding protein(VDBP)and coagulation?related parameters in peripheral blood between pre?eclampsia,then analyze their relationships with the onset or development of pre?eclampsia. Methods A total of 30 women with severe pre?eclampsia(SPE)and 30 women with mild pre?eclampsia(MPE)were enrolled for the study and randomly chosen as trial group. 30 normal pregnancies with matching gestational ages were selected as control group?1 and 30 normal full?term pregnancies were randomly chosen as control group?2. The levels of GSN,VDBP,platelet(PLT),prothrombin time(PT),thrombin time(TT),activated partial thromboplas?tin time(APTT),fibrinogen(FIB),and D?dimer were compared between those groups. Results The levels of GSN,VDBP and PLT,PT,APTT, FIB in SPE group were significantly lower than that of MPE group(P<0.05),and the level of D?dimer was significantly higher(P<0.05). In healthy pregnant women between control group?1 and control group?2,GSN fell during gestational weeks,with a concomitant rise in VDBP with no significance(P>0.05). There were no statistical difference among all the levels of coagulation?related parameters in healthy pregnant women(P>0.05). Conclusion GSN and VDBP levels in pre?eclampsia are significantly lower than that of normal pregnant women,along with pathological hy?percoagulative state,and which are related to severity of disease.
