OBJECTIVE:To compare the incidence of cerebral events in patients with ischemic cerebrovascular disease compli-cating with cerebral microbleeds(CMBs)at the last stage of antiplatelet agent use. METHODS:140 patients with ischemic cerebro-vascular disease were selected from Beijing Anzhen Hospital Affilicated to Capital Medical University during Jan. 2013-Jan. 2014, and then divided into CMBs group and non-CMBs group according to whether complicated with CMBs,with 70 cases in each group. After followed up for 1 year(regular use of aspirin 100 mg/d and/or clopidogrel 75 mg/d),the incidence of recurrent cere-bral infarction and cerebral bleeding and mortality were compared. RESUTLS:The incidence of recurrent cerebral infarction was 12.9% in CMBs group and 8.6% in non-CMBs group,without statistical significance(P=0.412);the incidence of cerebral bleed-ing was 10.0% in CMBs group and 1.4% in non-CMBs group,with statistical significance(P=0.029);the mortality of cerebro-vascular event at the last stage was 5.7% in CMBs group and 4.3% in non-CMBs group,without statistical significance (P=0.698). CONCLUSIONS:The risk of cerebral bleeding increase in patients with ischemic cerebrovascular disease complicating with CMBs after the application of antiplatelet agent. For patients with ischemic cerebrovascular disease complicating with CMBs,the application of antiplatelet agent should be based on the complete judgment and weighing of benefit and bleeding risk.

BACKGROUND:Culture supernatant containing myocardiocyte has been demonstrated to induce differentiation of bone marrow-derived mesenchymal stem cel s into myocardiocyte-like cel s. This may associate with some or several cytokines in the culture supernatant.
OBJECTIVE:To explore if the supernatant of myocardiocyte induces bone marrow-derived mesenchymal stem cel s to differentiate into myocardiocyte-like cel s is associated with the different cytokine content in the supernatant of myocardiocyte.
METHODS:Bone marrow-derived mesenchymal stem cel s were isolated and cultured in vitro by the whole bone marrow adherent culture. Cardiocytes were isolated and cultured by enzyme digestion. Bone marrow-derived mesenchymal stem cel s (1×108/L) and cardiocytes (1×105/L) were cultured for 72 hours and the supernatant was col ected. Hepatocyte growth factor, insulin-like growth factor 1, platelet-derived growth factor, stem cel factor, fibroblast growth factor and vascular endothelial growth factor levels in culture supernatant of bone marrow-derived mesenchymal stem cel s and cardiocytes were detected by enzyme-linked immunosorbent assay.
RESULTS AND CONCLUSION:The content of insulin-like growth factor 1, platelet-derived growth factor and fibroblast growth factor in the supernatant of cardiocytes was significantly higher in cardiocytes group compared with bone marrow-derived mesenchymal stem cel s group (P<0.01). Results indicated that insulin-like growth factor 1, platelet-derived growth factor and fibroblast growth factor in the supernatant of cardiocytes may have capability to induce bone marrow-derived mesenchymal stem cel s to differentiate into myocardiocyte-like cel s, and insulin-like growth factor 1 may serve as the main cytokine.
