Abstract:
This study was aimed to investigate the expression and activity of membrane surface tissue factor (TF) of monocytes and platelets in peripheral blood cells from patients with cerebral infarction and their clinical significance. The TF expressions in monocytes and platelets from 25 patients with cerebral infarction were detected by flow cytometry, the TF activity was detected by chromogenic reaction method, and compared with 24 normal people used as control. The results showed that the TF expressions of monocytes and platelets in peripheral blood cells from patients with cerebral infarction were significantly higher than that in normal controls (p<0.01), and TF activity was also higher in patients than that in controls (p<0.01). In conclusion, the expression and activity of membrane surface in patients with cerebral infarction were enhanced, the hematocyte-derived tissue factor as a trigger in coagulation pathway is involved in pathological thrombosis in patients with cerebral infarction.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
