RESUMO
OBJECTIVE: To tentatively establish a diagnosis and treatment mode for effectively controlling the progress of cerebral microlesions (CM) and preventing the incidence of cerebral infarction (CI) by comparing different intervention modes for treating CM. METHODS: Using a prospective, nonrandomized, controlled trial, 408 subjects with multiple CM were assigned to the Chinese medical pharmacy intervention group (Group A, 100 case), the aspirin intervention group (Group B, 104 cases), the negative control group (Group C, 100 cases), and the non-intervention group (Group D, 104 cases). No intervention was given to those in Group D. Patients in the other 3 groups were intervened by life style and routine therapies of vasculogenic risk factors. Those in Group A took Guizhi Fuling Pill (GFP) and earthworm powder additionally. Those in Group B took aspirin additionally. They were routinely followed-up. The CM, the changes of vasculogenic risk factors, and the incidence rate of CI were compared among the 4 groups. RESULTS: The total effective rate of CM was 66.67% in Group A, obviously higher than that of Group B (52.32%), Group C (42.86%), and Group D (37.04%), respectively. It was obviously higher in Group B than in Group D, showing statistical difference (P <0.01, P <0.05). After treatment, the serum levels of LDL-C, TC, and TG were obviously lower in Group A than in Group B (P <0.05); the serum levels of LDL-C and TC were obviously lower in Group A than in Group C (P <0.01); the systolic pressure was obviously lower in Group A than in Group D (P <0.05). The systolic pressure and the serum TC level were obviously lower in Group C than in Group D (P <0.05). The incidence rate of CI was 2.17% (2/92 cases) in Group A, obviously lower than that of Group C (11.36% ,10/88 cases) and Group D (14.44%, 13/90 cases), showing statistical difference (P <0.05). But there was no statistical difference between Group A and Group B (6.74% ,6/89 cases) (P >0.05). CONCLUSIONS: GFP combined earthworm powder could treat CM, control vasculogenic risk factors, and finally prevent the incidence of CI. Standard Chinese medical intervention mode showed the optimal effects in treating CM and preventing the incidence of CI, and perhaps it could be spread clinically.
