Current status and development trend of coagulation factor Ⅷ activity / 中华检验医学杂志

The detection of coagulation factor Ⅷ activity plays an important role in the diagnosis, typing, efficacy monitoring and detection of inhibitor titer in hemophilia A, acquired hemophilia A and von Willebrand disease. However, due to the diversity of detecting systems, the difference of reagent composition, the existence of interfering substances and other influence factors, the detection of coagulation factor Ⅷ activity in the laboratories in China still needs to be improved.

Pediatric primary nephrotic syndrome patients comprehensive detection of plasma protein Z and coagulation factor Ⅷ activity analysis / 国际检验医学杂志

Objective To investigate the changes of plasma protein Z and coagulation factor Ⅷ activity in children with primary nephrotic syndrome.Methods 94 children with primary nephrotic syndrome were se-lected as the observation group,and 63 healthy children were selected as the control group.The blood samples of peripheral blood were collected from the study group,and plasma protein Z and coagulation factor Ⅷ were measured by enzyme linked immunosorbent assay.Enzyme linked immunosorbent assay was used to measure plasma protein Z and coagulation factor Ⅷ.The changes of plasma protein Z and coagulation factor Ⅷ in the two groups were compared,and the changes of plasma protein Z and coagulation factor Ⅷ in the acute and re-covery phase,and the correlation between plasma protein Z and coagulation factor Ⅷ were observed.Results The observation group of plasma protein Z level is lower than the control group,blood coagulation factor Ⅷlevels higher than the control group,and the difference was statistically significant(P<0.05);plasma protein Z level in acute stage is lower than the recovery period,and coagulation factor Ⅷ level is higher than the recov-ery period,the differences were statistically significant(P<0.05);plasma protein Z and coagulation factor Ⅷwas negatively correlated.Conclusion The plasma protein Z level in children with primary nephrotic syn-drome is significantly reduced,and the activity of coagulation factor Ⅷ is significantly increased.Detection of plasma protein Z and coagulation factor Ⅷ level can predict primary nephrotic syndrome in children.
