Abstract
Objective To observe the changes of CD11 a, CD11c and CD54 and its' influence on prognosis after the intervention of hyperbaric oxygen(HBO) in patients with acute cerebral infarction (ACI).Methods Sixty-four ACI patients were divided into control group( C group) and HBO therapy group( HBOT group).C group (33 cases) received routine treatment only, HBOT group ( 31 cases) received routine treatment and hyperbaric oxygen therapy.CD 11 a, CD11 c and CD54 were measured in both groups at ≤72h, the 7th d, 10th d, 12th d, 20th d after ACI, and neural functional damage scores(NDS) were evaluated at the same time.CD11a, CDllc and CD54 were also measured in normal control group (25 cases).Results Plasma levels of CD11a, CD11c and CD54 rose significantly both in HBOT group and C group and peaked at≤72 h after ACI, there was no significant difference between two groups (P > 0.05), then declined at the 7th d.Levels of CD11 a, and CD11c maintained at the peak for 7 d in H BOT group and for 10 d in C group.CD54 peak remained for 10 d in HBOT group, and for 12 d in C group.A correlation analysis and linear regression analysis showed that the NDS levels at 20th d (short-term curative effect), 6 months and 12 months (long-term outcome) could be explained by 97.3 % , 96.7% and 96.6% , respectively by the admission levels of CD11 a and/or CD11 c and/or CD54 and other related factors.Conclusion After hyperbaric oxygen therapy peak level duration of CD11a, CD11c and CD54 could be shortened.Hyperbaric oxygen could influence intercellular adhesion molecule changing process, reduce leukocytes adhesion, decrease expressions of CD11a CD11c and CD54, and protect ACI patients.Before treatment, expression of CD11a, CD11c and CD54 may predict the severity, short or long-term outcome and prognosis of ACI patients.
