[Effect of erigeron injection on platelet level of CD62p and serum content of TNF-alpha and IL-6 in patients with acute cerebral infarction].

OBJECTIVE

To investigate the clinical effect of Erigeron injection (El) on positive expression rate of CD62p in platelet and content of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) in serum of patients with acute cerebral infarction (ACI).

METHODS

Sixty-eight patients with ACI were randomly divided into the treated group (n = 35) and the control group (n = 33). Conventional treatment were given to both groups, and EI 40 ml/d were given additionally to the treated group, the treatment course for both groups was 15 days. The positive expression of platelet CD62p and the serum TNF-alpha and IL-6 in patients before and after treatment were determined with flow cytometric (FCM) and electrochemical-luminescence (ECL) techniques respectively.

RESULTS

The total curative effect in the treated group were significantly higher than that in the control group (P < 0.05). Levels of platelet CD62p and serum TNF-alpha and IL-6 in ACI patients before and after treatment were significant higher than those in the healthy group (P < 0.05), all the three parameters were significantly decreased after treatment, and the lowering in the treated group was more significant than that in the control group (P < 0.05).

CONCLUSIONS

The effect of El on ACI patients may relate to its action in down-regulating the expression of platelet CD62p, alleviating the immune response and inflammatory injury of central nervous system induced by cytokines.
