Objective: To explore the effect of salvianolate combined with the conventional therapy on acute ischemic stroke and observe the influence on serum inflammatory cytokines of interleukin-6(IL-6).Methods: According to the random number table, 70 patients were randomly divided into the observation group (n =35) and the control group (n =35), and both were given the conventional therapy for acute ischemic stroke.The observation group was given intravenous injection of 200mg salvianolate in 250ml normal saline once a day additionally.The treatment course was 2 weeks.Another 30 persons with physical examination were in the healthy control group.The neurologic damage deficiency score (NIHSS score) was evaluated after the 3-, 7-,10-and 14-day treatment in the groups, the serum IL-6 in 24 h after onset, and after the 3-, 7-,10-and 14-day treatment was detected and compared with that in the healthy control group.Results: After the 7-day treatment, NIHSS score in the observation group decreased significantly when compared with that on admission (P＜0.05), and remained the decreasing trend.After the 10-day treatment, NIHSS score in the control group decreased significantly when compared with that on admission (P＜0.05).After the 7-day treatment, NIHSS score in the observation group was lower than that in the control group (P＜0.05).Compared with that in the healthy control group, the serum level of IL-6 in the observation group and the control group was higher in 24 h of admission (P＜0.05).The serum level of IL-6 in the observation group decreased after the 7-day treatment, and was similar to that in the healthy control group after the 14-day treatment (P＞0.05).The serum level of IL-6 in the control group decreased after the 10-day treatment, while was higher than that in the healthy control group during the whole study period (P＜0.05).The serum level of IL-6 in the observation group was lower than that in the control group after the 7-day treatment (P＜0.05), and the peak value in the observation group was notably lower than that in the control group (P＜0.05).Conclusion: Salvianolate combined with the conventional therapy can effectively decrease the NIHSS score and the content of IL-6 in the patients with acute ischemic stroke, which shows better effect than the conventional therapy alone.
