Abstract:
BACKGROUND: With the deep investigations of pathophysiological mechanism of acute cerebral infarction, it is discovered that inflammation occupies an important stance in the ischemic injuries of central nervous system ( CNS ), in which tumor necrosis factor-αt (TNF-α), interleukin- 1β(IL-1β), and soluble intercellular adhesion molecule(sICAM-1) become hotspots in the researches.OBJECTIVE: To investigate the relationship between the levels of serous inflammatory cell factors and the course of the disease, the severity of the situation in patients with ischemic stroke.DESIGN: A case-control study based on patients and healthy individuals.SETTING: Department of neurology in a university hospital.PARTICIPANTS: Fifty ischemic stroke patients including 23 males and 27 females with an average age of(60.26 ± 8.77) years old were selected from the outpatient and inpatient Departments of Neurology of the Renmin Hospital of Wuhan University between January 2001 and December 2003. Forty healthy controls including 18 males and 22 females with an average age of (61.05 ± 8.09) years old were selected from the subjects who had physical check up at outpatient department during corresponding period.INTERVENTIONS: Serous TNF-α, IL-1 β and sICAM-1 levels were detected by double-antibody-ELISA.MAIN OUTCOME MEASURES: Serous levels of TNF-α, IL-1β and sICAM-1 in patients with ischemic stroke of different stage, with different infarction volume and different neural functional defects.RESULTS: Serous TNF-α, IL-1β and sICAM-1 levels of patients with cerebral infarction during acute phase and convalescence were significant higher than that of control group( P ＜ 0.01 ), and the levels was significantly higher in acute phase than convalescence ( P ＜ 0.05 ) . The elevation was closely correlated with the degree of neural functional defect and the size of infarction volume, and furthermore, the serous content of TNF-α was also correlated with IL-1β and sICAM-1 levels.CONCLUSION: TNF-α, IL-1β and sICAM-1 interact and participate in the inflammation and reperfusion injury of acute cerebral infarction. Surveillance on them can provide experimental indicators for early clinical therapy and rehabilitative intervention, which is good for the control of the development and recurrence of stroke.
