[Protective effects of artesunate combination on experimental cerebral malaria and nerve injury].

Cerebral malaria (CM) is the leading cause of death in children under 5 years in Africa, severe neurological sequelae may occur in surviving children. Although artesunate has made breakthrough progress in the clinical treatment of CM, the clinical problems of high mortality and high morbidity have not yet been completely resolved. In this study, an experimental cerebral malaria (ECM) model was established by infecting C57BL/6 mice with Pb ANKA (Plasmodium berghei ANKA) to compare parasitemia level, survival rates, and rapid murine coma behavior scale scores, cerebral microvascular obstruction, haemozoin deposition in the liver, body temperature and weight to investigate the anti-cerebral malaria effect of the artesunate compound combination. The results showed that the artesunate compound combination could improve the survival rate of Pb ANKA-infected mice, reduce the level of parasitemia, effectively improve the symptoms of ECM neurological injury, reduce cerebrovascular obstruction and haemozoin deposition in the liver, and also significantly improve body temperature, weight and other basic indicators. The results showed that the artesunate compound combination improved the pathological changes and neurological damage caused by CM. It is expected to provide a theoretical basis for human cerebral malaria patients in clinical adjuvant therapy.
