Human exposure to environmental chemicals may play a role in the pathogenesis of recurrent spontaneous abortions described (Ursa). Bisphenol A (BPA) and bisphenol S (BPS) has been suggested to affect reproductive health. However, the mechanism is still unclear. To explore the relationship between BPA and BPS exposure and oxidative stress and immune homeostasis, we conducted a cross-sectional and reveal the level of BPA and BPS in relation to these two factors should be involved in miscarriage.
Ursa 111 patients were recruited and we analyzed urinary concentrations of BPA and BPS, biomarkers of oxidative stress (8-hydroxydeoxyguanosine and 8-isoprostane) and immune serum biomarkers balance ( IL -1β, IL -2, IL -4, IL -6, IL -8, IL -10, IL – 12p70 , IL -13, TNF-α, TGF-β and IFN-γ). Multivariate linear regression models were used to evaluate the relationship between exposure to bisphenols and biomarker results. After adjustment for age, BMI, menstrual cycle, and the history of parity, BPA adjusted creatinine was significantly associated with an increased 8-isoprostane (β = 0.74, 95% CI = 0.07, 1.41; p = 0.031) and IFN -γ (β = 0.18, 95% CI = 0.00, 0.36; p = 0.046). There is no statistical correlation between CPM and biomarkers of oxidative stress or immune balance is observed when all participants were analyzed.
Further analysis revealed that in the subgroup of BPS> limit of detection (0.01 ng / ml), creatinine adjusted BPS was significantly associated with an increase in IL -10 (β = 0.22, 95% CI = 0.00 , 0.45; p = 0.048). Our findings indicate that exposure to BPA and BPS may be associated with oxidative stress and immune imbalance in patients Ursa. Overall, our work might suggest a potential pathogen and the etiologic association between bisphenols, biomarkers and Ursa, which offers a hypothesis for further study.

The role and function IκKα / β in monocytes disorders
The following major trauma, sepsis or surgery, some patients show a disturbance of monocyte inflammatory response characterized by decreased response following bacterial challenge. To investigate this phenomenon is poorly understood, we adopted the model of endotoxin tolerance in vitro utilizing primary Human CD14 + monocytes to focus on the effects of impairment IκKα / β, an important part of the pathway NF.
Impaired monocyte IκKα decreased mRNA and protein expression and decreased phosphorylation IκKα / β complex. secretome monocytes disorders that show different traces of cytokine / chemokine monocyte-naive, and that TNF-α is the most sensitive cytokine or chemokine in this arrangement impairment. Inhibition IκKα / β with novel selective inhibitor of monocyte phenotype reproduced disturbed by decreased production of TNF-α, IL -6, IL – 12p70 , IL -10, GM-CSF, VEGF, MIP-1β, TNF-β, IFN-α2 and IL -7 in response to LPS challenge.

surgical patients with infection is also exhibited impaired monocyte phenotype and decreased SITPEC, TAK1 and MEKK gene expression, which is important for IκKα / β activation. atients with infection is also exhibited impaired monocyte phenotype and decreased SITPEC, TAK1 and MEKK gene expression, which is important for IκKα / β activation. Our results emphasize that monocyte function disorders is, at least in part, related to the unregulated IκKα / β activation, and that IκKα / β possibly involved in the installation of monocyte inflammatory response is sufficient. Future studies may want to focus on adjuvant therapy to increase IκKα / β function to restore the function of monocytes in the issue of clinical importance.
