ABSTRACT
Objective To investigate the treatment of threatened abortion progesterone maternal serum pro-gesterone -induced blocking factor (PIBF)levels and clinical significance,in order to be able to provide theoretical references of progesterone treatment of threatened abortion.Methods Threatened abortion women (study group)and non -threatened abortion women (control group),50 patients in the observation group given progesterone therapy, enzyme -linked immunosorbent assay (ELISA)was used to detect serum progesterone and PIBF levels of the obser-vation group before treatment and two weeks later,the control group was selected and named after two weeks.Results Observation group after treatment 47 patients progesterone tocolysis successful,success rate was 94.00%,tocolysis bleeding stop time 8.42d,abdominal pain time 11.32d.PIBF of the observation group was (313.52 ±90.43)mmol/L, which was lower than that of the control group (398.47 ±104.25)mmol/L,the difference was statistically significant (t =10.90,P 0.05).Conclusion Reduced PIBF during early pregnancy may be one of the reasons of threatened abortion,the use of progesterone therapy can increase PIBF expression,possibly through this pathway plays a role in tocolysis,so when using progesterone tocolysis monitoring PIBF levels helps evaluate the efficacy of tocolysis.
ABSTRACT
Objective To study the expression of splice variant of progesterone-induced blocking factor (PIBF) of healthy adult and hepatocellular carcinoma (HCC) patients. Methods Western blot was used to find out the expression in 3 normal livers and tumor and para-tumor tissue of 8 HCC patients. Use T Test to compare the difference. Immunohistochemistry was used to detect the expression in tumor and para-tumor tissue of 48 HCC patients. The splice variant of PIBF serum concentrations of 103 healthy adult, pre-operation and part of 5 days post-operation of 109 HCC patients was tested with ELISA. Result The expression of HCC tissue is lower than para-tumor tissue. The serum concentrations of healthy adult and HCC patients is 73.04 ± 6.29 ng/mL and 49.10 ± 4.07 ng/mL, and the difference was statistically significant (P=0.010). The analysis of blood concentrations of pre-operation and part of 5 days post-operation of 15 HCC patients indicate that the expression of pre-operation is lower than post-operation, and the difference was statistically significant (P = 0.008). Conclusion The splice variant of PIBF is low expressed in HCC tissue and serum. PIBF is a potential protein plays important role in cancer.
