Objective To evaluate the effectiveness of gamma knife and radioactive effect for glioma.Methods MR images of 106 cases with glioma treated by gamma knife were analysed based on classified.Results The effectiveness of gamma knife was the best for ependyoma and oligodendroglioma,the secondly for astocytoma (Ⅰ~Ⅱ) .The effectiveness for astrocytoma( Ⅲ~Ⅳ)was not well.The effective rate in 1 year after treament for astocytoma(Ⅰ~Ⅱ)was far higher than 2~3 years later.The 2nd year after treatment was the peak time for edema around tumor and the special radioactive contrast enhancement on MR.Conclusion Gamma knife is a effective therapy for glioma,especially for ependyoma,oligodendroglioma and astocytoma(Ⅰ~Ⅱ).The radioactive effect showed as edema and radioactive contrast enhancement on MR can become smaller or disappear 2 years later after treament.

The blood donation, component preparation and manufacturing, laboratory, issuing and quality control were studied and compared between the UK and China, in order to learn British experience in the clinical practice and blood services. The age limits of blood donors, blood collection units, donation times per year, laboratory items, and the types(volumes) of component preparation and manufacturing in the UK are more superior than those in China. In addition, the blood quality monitoring and regarding indicators are more scientific and reasonable in the UK. The full reimbursement of clinical blood expenses for patients has been realized in the UK. The British experience in continuous safeguard of the blood safety and balance of requirement and availability contributes to the constant and scientific development of British blood services over the years, and is worthy of references.
