Abstract:
Objective:To investigate the role of Th1/Th2 shift in unexplained recurrent spontaneous abortion (URSA) and to study the effect and molecular mechanism of Bushen Guchong decoction on URSA treatment by regulating Th 1/Th2 paradigm.Methods:30 cases of URSA patients were given Bushen Guchong decoction administration ; meanwhile,30 cases of normal pregnancy women were taken as control group.Th1/Th2 paradigm in peripheral blood monocytes of URSA patients before and after Bushen Guchong decoction administration was detected by flow cytometry.Moreover,the mRNA expression of the specific transcription factors for Th1 and Th2 subsets -T-bet and GATA-3 were detected by RT-PCR assay.Furthermore,the relationship between the Th1/Th2 paradigm and the uterine bleeding time after Bushen Guchong decoction administration was analyzed by Pearson correlation and re -gression tests.Results: Compared with normal pregnancy women , the proportion of Th1 subset of URSA patients was increased significantly (P<0.05),while the proportion of Th2 subset was decreased markedly (P<0.05).Additionally,the ration of Th1/Th2 subsets was increased in URSA women (P<0.05).After Bushen Guchong decoction treatment ,the proportion of Th1 subsets in URSA patients and T-bet mRNA expression were up-regulated significantly ( P<0.05 ) , whereas the Th2 proportion and GATA-3 mRNA expression were down-regulated obviously (P<0.05).Moreover,the ratio of Th1/Th2 was decreased significantly (P<0.05).Correlation analysis showed that the uterine bleeding time was positively related to both the proportion of Th 1 and the ratio of Th1/Th2, while negatively related to the proportion of Th 2 subsets.Conclusion:Th1/Th2 shift was involved in URSA.Bushen Guchong decoction up-regulated the transcription level of GATA-3 and down-regulated the transcription level of T-bet.Thereby, Bushen Guchong decoction exerted the curative effect on URSA by revising Th 1/Th2 shift.
