Currently, the study of the immune microenvironment of the maternal-fetal interface has been a heated topic in reproductive immunology research. More and more studies show that the immune imbalance in the maternal-fetal interface plays a very important role in the incidence of intrahepatic cholestasis of pregnancy(ICP). However, the precise etiology and mechanism of immune imbalance in the occurrence of ICP is still unknown. In order to clarify the potential immunologic mechanisms of ICP, this review summarizes the recent studies of the decidual immunology microenvironment and the potential immunologic mechanisms related to the development of ICP.展开更多

The levels of TXA2/PGI2 balance-related indicators, bone metabolism indicators and stress hormones in serum as well as the expression levels of stress molecules in peripheral blood were measured before surgery and 3 d after surgery.Results:Compared with those of same group before surgery, serum 6-keto-PGF1α, t-PA, PICP, BALP and OCN levels of both groups of patients were significantly lower whereas serum TXB2, PAI-1, D-D,β-CTX, RANKL, NE, COR and ANG-Ⅱ levels as well as peripheral blood NF-κB and HSP70 expression were significantly higher after surgery, and serum 6-keto-PGF1α, t-PA, PICP, BALP and OCN levels of experimental group after surgery were higher than those of control group whereas serum TXB2, PAI-1, D-D,β-CTX, RANKL, NE, COR and ANG-Ⅱ levels as well as peripheral blood NF-κB and HSP70 expression were lower than those of control group.Conclusion:Danshen Chuanxiongqin therapy after proximal femoral fracture surgery can adjust the TXA2/PGI2 balance, improve the bone metabolism and reduce the stress level.展开更多
