Objectives To explore the pathological characteristics, treatment and prognosis of medulloblastoma (MB) in children. Methods Pathological characteristics, treatment outcomes and other clinical data were retrospectively analyzed in 60 children with MB. Results The MB in all 60 children were high-grade tumor. The pathological type was mainly classic (45 cases, 75.00%) and other subtypes were seen in 15 cases (25.00%). Forty-eight (80.00%) children had total resection by micro-surgery, 9 children (15.00%) subtotal resection, and 3 children (5.00%) partial resection. Twenty-seven children were treated by radiotherapy after surgery, 6 children were treated by chemotherapy after surgery, and 5 children were treated with radiotherapy combined chemotherapy after surgery. Thirty-eight cases were followed up. The 2-year survival and disease-free survival rates were 63.16%and 55.26%. The 5-year survival and disease-free survival rates were 26.32%and 18.42%. The children with des-moplastic/nodular type survived significantly longer than the children with large cell anaplastic. The children with total resection survived significantly longer than the children with partial resection. The children with radiotherapy or chemotherapy survived significantly longer than the children without chemotherapy (P<0.05). Conclusions MB in most of children is high-grade tu-mors and the prognosis is poor. The pathological type is related with prognosis. Microsurgical total resection is the first choice of treatment. Postoperative radiotherapy and chemotherapy can increase the survival rate.

Objective To study the relationship between white blood cell(WBC) count and cardiac events in acute ST-elevation myocardial infarction(STEMI) patients treated with reperfusion in the early stage. Methods Two hundred and thirty-five patients with acute STEMI were divided into two groups:percutaneous coronary intervention group (PCI group, 97 patients) and thrombosis therapy group (138 patients). WBC count and cardiac events of the two groups before and after treatment (3 h and the second day and the third day) were recorded and compared. Results The level of WBC count had no changes in two groups before and after treatment in first 3 h (P>0.05) , while the level of WBC count was significantly decreased, and the level of WBC count was significantly lower in PCI group than that in thrombosis therapy group (P<0.05). The rate of no cardiac events and two cardiac events in two groups has no significant differences (P > 0.05). The rate of one cardiac events in PCI group was significantly higher than that in thrombosis therapy group (P<0.05). The rate of three cardiac events in PCI group was significantly lower than that in thrombosis therapy group (P<0.05). WBC count had a positive correlation with cardiac events rate (r = 0.231, P < 0.05). Conclusions Primary percutaneous coronary intervention decreases WBC count and cardiac events rate. In patients with acute myocardial infarction, level of WBC count has positive relationship with cardiac events.
