Objective To evaluate the effect of an Internet support program on uncertainty in illness in breast cancer patients after operation. Method One hundred and nineteen breast cancer patients after surgery who were discharged from Shanghai Cancer Hospital were assigned into the control group (63 cases) and the intervention group (56 cases). A 12-week Internet support program was offered to the patients in the intervention group, while the patients in the control group received the routine follow-up. Measurement of uncertainty in illness was taken at the sixth week and the twelfth week after the baseline survey. Results The total score of the uncertainty in illness as well as the factor scores of ambiguity and lack of information showed downward trend in both the intervention group and the control group, and the three indexes in the intervention group declined more rapidly than those in the control group. The scores of the three indexes in the intervention group were significantly lower than those in the control group at the twelfth week. Conclusion The Internet support program which offers abundant information, multi-disciplinary cooperation and real-time interaction intervention is an effective approach in reducing uncertainty in illness for breast cancer survivors.

Objective To evaluate the effect of a nurse-led case management intervention on arm function and uncertainty for women with breast cancer.Methods 90 women with breast cancer were divided into the intervention group and the control group according to their nurses,with 45 patients in each group.All participants were followed six months after surgery.The intervention group attended a 6-month nurse-led case management program,while the control group received the routine care and follow-up only.Questionnaires on arm function and uncertainty were administered 1 month,3 months and 6months after the surgery respectively.Score changes were compared by repeated-measure ANOVA and MANOVA.Results The arm function of the intervention group was better than the control group,except for the 10th day after the operation,there were significant differences at other three time points.The disease uncertainty level of the intervention group was better than that of the control group,except for the dimension of unpredictability,there were evident differences in other dimensions at other three time points.Conclusions The nurse-led case management intervention could improve arm function recovery and decrease the uncertainty to disease of breast cancer survivors.

Objective To discuss the clinical value of susceptibility weighted imaging (SWI) in the brain vascular malformations. Methods Imaging data of 34 patients with brain vascular malformations proved by digital subtraction angiography (DSA) or pathology obtained on Siemens Sonata 1.5T MR system were studied prospectively, and compared with those of conventional MRI (cMRI) and SWI. Results All 41 lesions of 34 patients with brain vascular malformations showed clearly by SWI. These patients were diagnosed by surgical findings or DSA. These nidus comprised 19 cavernous angiomas, 9 arteriovenous malformations and 6 cerebral venous malformations. Conclusion SWI should be used for clinical diagnosis of brain vascular malformations, and providing more complete and detailed information combining with other sequence.
