Objective To explore the value of MSCTU in ureterovesical junction diseases.Methods MSCTU data in 41 patients with different diseases in ureterovesical junction were retrospectively analyzed.All patients underwent plain and triphase contrast en-hanced CT scans.The primary imaging data were transmitted to a worksation to get the maximum intensity projection (MIP),vol-ume rendering (VR),multiplanar reconstruction (MPR)and curve plannar reconstruction (CPR)images.Results (1)CT showed congenital abnormality in 7 patients including ectopic ureteral orifice in 1,megaloureter in 1,duplication of the urter in 4 and uret-erocele in 2.(2)Urinary stone in 25 with bladder filling defect in 1 1.(3)Tumor in 9 including polyp in 1,urothelial carcinoma in 6 and prostate cancer in 2.MSCTU clearly showed the location,shape,size of the ureterovesical junction diseases and the relationship with surrounding structures.Conclusion MSCTU plays an important role in diagnosis of ureterovesical junction diseases with an ac-curate rate of 97.5%(40/41).

Objective To explore and evaluate the effect of 32P and pinyangmycin injected in combination for the treatment of maxillofacial hemangioma. Methods The patients were randomly divided into three groups. The first group of patients was treated with 32P; 100 patients were enrolled in this group, of which 37 were male and 63 female. 32P dosage between 0.37 and 0. 74 MBq per cm3 was prepared together with 0.5 ml of 2 %lidocaine, and appropriate normal saline, and then the mixture was injected into hemangioma every two weeks. The second group was given pinyangmycin, and the third group received both 32P and pinyangmycin. The second group included 30 male and 60 female, and the third group 64 male and 136 female. The dose and frequency were given as the same to the first group. Results 88.5 % of patients were cured using both 32P and pinyangmycin, and the cure rate was 77.0 % and 71.7 % with either 32P or pinyangmycin. Conclusion These results prove that 32P and pinyangmycin injected in combination for the treatment of maxillofacial hemangioma is more effective than either 32P or pinyangmycin alone, and furthermore, the method is easy, safe and has less complications.

Beijing has been one of the epicenters attacked most severely by the SARS-CoV (severe acute respiratory syndrome-associated coronavirus) since the first patient was diagnosed in one of the city's hospitals. We now report complete genome sequences of the BJ Group, including four isolates (Isolates BJ01, BJ02, BJ03, and BJ04) of the SARS-CoV. It is remarkable that all members of the BJ Group share a common haplotype, consisting of seven loci that differentiate the group from other isolates published to date. Among 42 substitutions uniquely identified from the BJ group, 32 are non-synonymous changes at the amino acid level. Rooted phylogenetic trees, proposed on the basis of haplotypes and other sequence variations of SARS-CoV isolates from Canada, USA, Singapore, and China, gave rise to different paradigms but positioned the BJ Group, together with the newly discovered GD01 (GD-Ins29) in the same clade, followed by the H-U Group (from Hong Kong to USA) and the H-T Group (from Hong Kong to Toronto), leaving the SP Group (Singapore) more distant. This result appears to suggest a possible transmission path from Guangdong to Beijing/Hong Kong, then to other countries and regions.
