Objective To evaluate the value of sonourethrography in the diagnosis of dysuria after bipolar transurethral plasmakinetic prostatectomy. Methods Sixty male patients with dysuria after bipolar transurethral plasmakinetic prostatectomy underwent sonourethrography and re-operation.The clinical data of these patients were reviewed. Results The sonourethrographic findings were similar with the operative findings in 57 cases.In the 60 cases,there were 11 cases with bladder neck closure,10 cases with bladder neck stricture,30 cases with urethral stricture (16 located at membranous urethra,12 located at pars cavernosa urethra and 2 in external orifice of urethra),5 cases with prostate remnant,1 case with calculi in prostatic urethra,2 cases with dysfunction of detrusor of bladder and 1 case with flap of internal urethral orifice,Conclusions Sonourethrography could be a reliable diagnostic method for dysuria after bipolar transurethral plasmakinetic prostatectomy.It may be helpful for clinical treatment.

Objective To investigate the application value of magnetic resonance diffusion tensor imaging (DTI) in auditory pathway of sensorineural hearing loss (SNHL) infants caused by cytomegalovirus (CMV) infection.Methods Thirtyone SNHL infants caused by CMV infections were included,and were divided into bilateral hearing loss (BPHL;n=13) group and unilateral hearing impairment (UPHL;n=18) group (including damaged side [lpsi subgroup] and the undamaged side [contrast subgroup]).Thirty-one infants without hearing loss as control group.The fractional anisotropy (FA),the mean diffusivity (MD),the axial diffusivity (AD) and the radial diffusivity (RD) of bilateral inferior colliculus (IC)and lateral lemniscus (LL) were obtained with DTI technique.The statistical analysis was performed.Results Compared with the control group,the FA value reduced and the RD value increased at LL and IC in the BPHL group (all P＜0.001).Compared with the contrast subgroup,the FA value reduced and the RD value increased at IC and LL in lpsi subgroup (all P＜0.001).Compared with the control group,the FA value reduced at LL in the lpsi subgroup,and FA values reduced and RD value increased at IC (all P＜0.001).Compared with the contrast subgroup,the FA value reduced and RD value increased at LL,and RD value increased at IC in the BPHL group (all P＜0.001).The FA value at IC was negatively correlated with auditory threshold (r=-0.966,P＜0.001).No matter in IC or in LL,the MD and AD had no statistical differences (all P＞0.05).Conclusion White matter of auditory pathway of SNHL infant caused by CMV infection is obviously altered,suggesting white matter myelination or myelin dysplasia.

OBJECTIVETo develop a brief version scale with good validity and reliability to evaluate self-management knowledge, attitude and behavior (KAB) of diabetes patients in a shorter time.

METHODS20 authority experts who specialized in the field of diabetes clinical and non-communicable disease self-management, and familiar with the relevant content of diabetes self-management were selected. Face to face and Email consultation methods were applied in two rounds delphi expert consultations to choose items from the Diabetes Self-management Knowledge, Attitude, and Behavior Assessment Scale (DSKAB, total scale, 98 items). In the first round of expert consultation, experts were asked to select the core items from every dimension and score the extent of familiarity and basis of judgment. In the second round of expert consultation, the significance of the core items which were selected by experts in first round, were graded. The items which entered into the brief scale were determined by harmonious condition of expert opinions.

RESULTSTwo rounds of consultation reclaimed 16 and 15 responses respectively, Positive coefficients of experts were 80% and 94% respectively, and both authoritative coefficients were 0.90. In the first round of consultation, experts selected 44.3 ± 6.2 items on average, 42 items were selected according to the integrity of the scale for measuring dimension and content at last. In the second round of consultation, experts thought that the 42 items could measure the important contents of each dimension comprehensive and representative, the item importance scores of knowledge, attitude, and behavior subscale were 8.42 ± 1.17, 8.61 ± 1.24, 8.61 ± 1.02 respectively, and the coordination coefficients of the three subscale were 0.36, 0.20, 0.49 (χ(2) were 89.74, 11.13, 96.03, P<0.05). The total coordination coefficient was 0.38 (χ(2) =199.36, P<0.001), which indicated the concentration of experts(')opinion was acceptable, showed the brief scale with good face validity and content validity.

CONCLUSIONThe brief scale could evaluate Diabetes Self-management KAB Scale rapidly and relatively comprehensive in groups or individuals diabetes with good face validity and content validity.
