Objective To study effect of virus inactivation/removal treated by solvent/detergent method and dry heating at 80℃, 72 h for inactivation in human coagulation factor Ⅷ.Methods Human coagulation factor Ⅷextracted from healthy human plas-ma were treated by solvent/detergent method and dry heating at 80℃, 72 h for inactivation .The virus inactivation effect was validated by adding the indicator virus ( PRV, Sindbis, HIV, EMCV, PPV).Results The methods could effectively inactivate lipid-enveloped and non lipid-enveloped viruses which could be used for virus inactivation /removal during human coagulation factor Ⅷexperiments , the residual amount of TNBP in production was less than one percent ten thousand (10 ppm), the residual Tween-80 concentration was less than one percent hundred thousand (100 ppm),which all met the safety standards .Conclusion and no significant change was ob-served in the activation and other indicators of human coagulation factor Ⅷ.

Alzheimer's disease (AD) is the most common type of dementia. Almost two-thirds of patients with AD are female. The reason for the higher susceptibility to AD onset in women is unclear. However, hormone changes during the menopausal transition are known to be associated with AD. Most recently, we reported that follicle-stimulating hormone (FSH) promotes AD pathology and enhances cognitive dysfunctions via activating the CCAAT-enhancer-binding protein (C/EBPβ)/asparagine endopeptidase (AEP) pathway. This review summarizes our current understanding of the crucial role of the C/EBPβ/AEP pathway in driving AD pathogenesis by cleaving multiple critical AD players, including APP and Tau, explaining the roles and the mechanisms of FSH in increasing the susceptibility to AD in postmenopausal females. The FSH-C/EBPβ/AEP pathway may serve as a novel therapeutic target for the treatment of AD.
