Objective To investigate the influence of support and intervention technique with multi-dimensions on uncertainty in illness for cancer children′s parents. Methods With convenience sampling method, a total of 74 cases of hematological malignant and solid tumor patients′ parents in Hematology and Tumor Centre of Children′s Hospital of Fudan University were selected. There were 35 cases in the intervention group, which were given multi-dimension-support and intervention technique for 8 weeks as well as regular chemotherapy and nursing care. There were 39 cases in the control group, who were only given regular chemotherapy and nursing care. The level of uncertainty in illness in both groups were evaluated after 8 weeks of the base-line investigation. Results The scores of uncertainty in illness reduced over time in both groups (F=95.402,P<0.01). After 8 weeks, the scores of the intervention group were lower than those of the control group (F=24.079,P < 0.01). Conclusions The all-round, multi-dimension and real-time techniques of support and intervention could decrease the level of uncertainty in illness for cancer children′s parents.

Objective To observe the changes of PECAM-1,Bcl-2 and Bax expressed by ischemic cerebrum of adult rats after focal cerebral ischemia. Methods Middle cerebral artery occlusion (MCAO) models were made by operation with Longa suture method in Wistar rats. The expression levels of PECAM-1,Bcl-2 and Bax at the 6th,12th,18th,24th,48th,72nd hour after MCAO were detected by immunohistochemistry staining. Results The expression levels of PECAM-1,Bcl-2 and Bax in cerebrum were significantly increased after MCAO. The expression levels of Bcl-2 we、re up to the peak at the 12th hour after MCAO, while the levels of Bax and PECAM-1 were up to the peak at the 24th and 48th hour after MCAO. At the 72nd hour after MCAO, the expression levels of PECAM.1.Bcl-2 and Bax were still higher than that in the control group(all P＜0.001).Conclusions PECAM-1,Bcl-2 and Bax participate in the different pathological stages of focal cerebral ischemia.

Objective To compare the efficacy and safety of singular double antithrombotie therapy (DT) using warfarin plus clopidogrel and the combined antithrombotie therapy of 3-month triple antithrombotie therapy (TT) using warfarin, aspirinand clopidogrel and 9-month double antithrombotie therapy (DT) for the patients with atrial fibrillation undergoing PCI. Methods Ninety patients with atrial fibrillation undergoing PCI were randomly divided into two groups evenly: one group was treated with dual antithrombotic therapy group (DT) and the other group with the combined therapy, e. g. 3-month triple antithrombotie therapy (TT) and 9-month double antithrombotie therapy (DT + TT for short). All patients were followed-up by 12 months. The two groups were compared in terms of incidences of death , myocardial infarction , stroke , target-vessel revascularisation , stent thrombosis and bleeding adverse events. Results The incidences of myocardial infarction, stroke, target-vessel revascularisation , stent thrombosis and bleeding adverse events in the TT + DT group were all significantly lower than the DT group (P < 0.05). The follow-up on the safety indicated that the rate of bleeding in the TT +DT group was insignificantly higher than the DT group (P > 0.05). Conclusion There is no significant difference in safety between the two groups. However, the therapy of TT + DT is more effective.
