Methods: The GSE2347219 dataset was analyzed using the GEO2R online tool. Sixty healthy pregnant women and sixty patients who were sPE were collected and serum was collected. The expression levels of serum B7-H4 and FAS were analyzed by RT-qPCR. The diagnostic value of FAS and B7-H4 for sPE and the predictive value of adverse cardiovascular outcomes were assessed by direct ROC analysis. Predictive probability values were analyzed by binary logistics regression followed by ROC analysis to assess the diagnostic value and predictive value of adverse cardiovascular outcomes of combined FAS and B7-H4. Cardiomyocytes were cultured using sPE serum, and hypertrophic and fibrotic factors were detected in the cells. Results: Analysis of GSE2347219 dataset showed that FAS and B7-H4 were upregulated in sPE placental tissues. Serum assay results indicated that FAS and B7-H4 were upregulated in sPE serum. Direct ROC analysis showed that FAS and B7-H4 could distinguish sPE cases from normal pregnant women and that they could predict adverse cardiovascular outcomes. Binary logistic regression analysis and ROC analysis showed that B7-H4 in combination with FAS could effectively differentiate sPE cases from normal pregnant women and effectively predict adverse cardiovascular outcomes. sPE serum culture elevated the levels of hypertrophic factors (ANP, BNP, and β-MHC) and fibrosis factor COL1A1 in cardiomyocytes. Conclusion: B7-H4 (VTCN1) in combination with FAS can be used as a diagnostic factor and predictor of adverse cardiovascular outcomes in patients with sPE.展开更多

In order to investigate the relationship between B7-H1 and immune escape of bladder cancer, B7-H1 expression in 50 cases of bladder cancer was detected by using immunohistochemical method. Survival curves were con- structed using the Kaplan-Meier method and independent prognostic factors were evaluated using the Cox regression model. Our results showed that the positive rate of B7-H1 immunostaining in normal bladder tissue and bladder cancer was 0 and 72% respectively. The expression of B7-H1 was strongly associated with the pathological grade, clinical stage and recurrence （P〈0.05）. The survival rate was significantly lower in patients with B7-H1 positive group than in those with B7-H1 negative group and multi-variable analysis revealed that B7-H1 could be regarded as an independent factor in evaluating the prognosis of bladder cancer. It is concluded that the expression of B7-H1 is strongly associated with neoplastic progression and prognosis of bladder cancer. The manipulation of B7-H1 may become a beneficial target for immunotherapy in human bladder cancer.展开更多
