Pathogenic significance and possible pathogenic mechanism of human endogenous viruses in development of schizophrenia / 病毒学报

The association between psychogenic illness and human endogenous viruses (HEVs), including human endogenous retrovirus and Borna disease virus, remains unclear. As the component of human genome, HEVs may become the joint of various pathogenic factors of schizophrenia (SZ), such as heredity, environment, and immunity. In this review, we strive to uncover the clinical and laboratory evidence for the roles and possible pathogenic mechanism of HEVs in the development of SZ.

Biological activities of the coagulation factor VIII, IX in platelet concentrates collected by platelet apheresis during preservation / 中国实验血液学杂志

The study was to explore the change of coagulation factor VIII and IX activities in the platelet suspension collected by platelet apheresis during storage at 22 degrees C. 18 samples of platelet concentrates were collected by the cs-3000 plus and stored at 22 degrees C and then FVIII: C, FIX: C activities were detected at 0, 12, 24, 48, 72, 96, 120 hours respectively by SYSMEX CA-1500. The results showed that FVIII: C activity was (100.51 + 44.02)% at 0 hour, and then decreased dramatically to 10% - 40% of primary level from 12 to 120 hours, while FIX: C activity was (120.93 +/- 20.50)% at 0 hour and decreased to 10% - 35% of primary level from 24 to 120 hours. In conclusion, FVIII and FIX in the platelet concentrates stored at 22 degrees C could keep their biological activities at physiologically high levels.
