Résumé
OBJECTIVE To investigate the clinical efficacy of Gushen antai pills combined with heparin sodium in the treatment of antiphospholipin antibody （ACA）-positive recurrent abortion. METHODS A total of 203 ACA-positive recurrent abortion patients were randomly divided into control group （n＝101） and combination treatment group （n＝102）. Control group was additionally treated with heparin sodium on basis of basic treatment， and combination treatment group was additionally treated with Gushen antai pills on the basis of control group. Serum samples were collected from patients， the levels of interleukin 6 （IL- 6）， tumor necrosis factor α （TNF-α）， cyclooxygenase 2 （COX-2）， β-human chorionic gonadotropin （β-HCG） and ACA were detected by enzyme-linked immunosorbent assay. The antibody-negative conversion rate was calculated， the clinical efficacy of the patient was observed， and the occurrence of adverse drug reactions was recorded. RESULTS After treatment， the pregnancy success rate and antibody-negative conversion rate of combination treatment group were significantly higher than those in the control group （P＜0.05）， and the abortion rate was significantly lower than that in the control group （P＜0.05）. Compared with before treatment， serum levels of IL-6， TNF-α and ACA in 2 groups were decreased significantly （P＜0.05）， while the levels of COX-2 and β-HCG were increased significantly （P＜0.05）； the changes of above indexes in combination treatment group were more significant（P＜0.05）. There was no statistical significance in the incidence of adverse drug reactions between 2 groups（P＞0.05）. CONCLUSIONS Gushen antai pills can maintain high expression of β-HCG， reduce the level of ACA and improve immune microenvironment in patients with ACA-positive recurrent abortion by increasing the serum level of COX-2 and decreasing the serum level of IL-6， so as to increase the success rate of pregnancy.
