Objective To explore the incidence and clinical characteristics of Han and Uygur pa- tients with ulcerative colitis(UC)in xinjiang.Methods Six hundred and ninty nine patients with UC from 2000 to 2006 were retrospectively reviewed.Patients were divided into 2 groups according to ethnic back- ground,including 522 Han patients and 177 Uygur patients.General data,age,clinical manifestation,le- sion range,lesion degree and complications were recorded in the 2 groups respectively.Results The detec- tion rate of UC by endoscopy in Urgur group was higher than that in Han group(P

OBJECTIVETo analysis the clinical characteristics of 1000 Hz probe tone tympanometry obtained from normal neonates who passed the OAE screening. To calculate the normal range of the variances of the tympanometry, which may serve as the guide for newborn hearing screening and detect middle ear function in neonates.

METHODSOAE screening were performed to screen the hearing with GSI-70 Automated OAE. The 1000 Hz probe tone tympanograms were obtained from 650 neonates who passed the TEOAE screening in both ears and were on the normal physiological conditions after birth with GSI Tympstar Version II Middle Ear Analyzer. The means, the standard deviation, the 95% confidence interval were analyzed.

RESULTSThe 1000 Hz tympanometric data showed the 1Y1B1G tympanogram in 732 ears (56.3%), the 1Y3B1G tympanogram in 145 ears (11.2%), the 0Y0B0G tympanogram in 269 ears (20.7%), other shapes in 154 ears (11.8%) according to the Vanhuyse model. The 1000 Hz tympanometric datas showed the single-peaked tympanogram in 967 ears, the 95% confidence interval of the tympanometric data were as follows: tympanometric peak pressure (Tpp) was from -55.0 to 180.0 daPa, peak compensated static acoustic admittance (Peak Ytm) was 0.03-1.18 mmHo, tympanometric width (TW) was 70.0-230.0 daPa.

CONCLUSIONSThe majority of 1000 Hz tympanograms from this study show the single-peaked in normal neonates. The 95% confidence interval of the tympanometric data may serve as a guide for hearing screening and detecting middle ear function in neonates.

OBJECTIVETo investigate the PET-CT manifestation and clinical features of patients with Waldenstrom macroglobulinemia(WM) .

METHODSThe clinical features, laboratorial examination results and PET-CT manifestation of 12 patients with WM were analyzed retrospectively.

RESULTSThe average age of 12 patients with WM was 63.5 years old, the most common incipient symptoms were fatigue and hyperviscosity syndrome. The median SUVof bone marrow was 4.9 (range of 2.1 to 21.9), with diffusely increasedF-FDG uptake in all the patients. In 6 patients, the median SUVof splenomegaly and lymphadenectasis was 3.2 (range of 2.3 to 5.2) and 5.2 (range of 3.6 to 11.2), respectively. The SUVof bone marrow, splenomegaly and lymphadenectasis did not related with white blood cell count, hemoglobin level, blood platelet count, β2- microglobulin level and serum monoclonal IgM of such patients, respectively (both P>0.5). In univariate analysis, serum monoclonal IgM and the SUVof lymphadenectasis were found to be the prognostic factors (both P<0.5).

CONCLUSIONTheF-FDG PET-CT feature of Waldenstrom macroglobulinemia has some characteristics which are helpful for setting up the clinical therapeutic schedule.
