Abstract:
AIM:There is little evidence proving the molecular mechanism of WenxinKeli ( WXKL) .This study tried to explore the gene ex-pression profile and pathology alteration of WXKL-treated rabbits with myocardial infarction .METHOD: Twenty male adult rabbits were randomly divided into 4 groups:sham, model, WXKL and captopril groups .Model, WXKL and captopril groups underwent the ligation of the left anterior descending coronary artery , while sham group went through an identical procedure without ligation .WXKL (817 mg? kg-1? d-1), captopril (8 mg? kg -1? d-1) and distilled water (model and sham) were administered orally to the rabbits. 4 weeks later, hearts were taken out for expression chip and pathological staining (HE, Masson and TUNEL) after echocardiography. RESULT:WXKL could down-regulate genes associated with inflammation (CX3CR1, MRC1, and FPR1), apoptosis (cathepsin C and TTC5) and neuro-hormonal system (ACE and EDN1), and up-regulate angiogenesis promoting gene like RSPO 3, which explained why WXKL group represented with better cardiac function , less histopathological injury and slighter apoptosis .CONCLUSION:WXKL plays an important role in suppressing inflammation , inhibiting renin-angiotensin system and alleviating apoptosis , and might be a promising Chinese medicine in treating patients with myocardial infarction .
