Objective This paper is to explore the relationship between the placement of the bone oscillator and bone-conducted thresholds to ASSR stimuli in adults with normal hearing and to investigate the amplitude and the threshold differences to bone-conducted auditory steady-state responses (BC-ASSR) stimuli between single - and multiple-stimulus conditions. Methods Two groups of subjects were selected with 0. 5, 1, 2 and 4 kHz brief tones repeated at the rate of 77, 87, 93 and 101 Hz using a B-71 bone oscillator either in single- or multiple ted no significant differences between mastoid and behind-the-ear placements. The mean and standard deviations of bone-conducted behavioral thresholds to ASSR stimuli at 0.5, 1, 2 and 4 kHz were 62.6±4.8,47.1±4.8,46.8cant difference between the two conditions while the mean and standard deviations of BC-ASSR thresholds at 0.5, 1, 2 and 4 kHz were 96.7±9.7,70.3±11.6,60.6±7.4,52.8±7.2 dB re: 1μN (ppe), respectively. Conclusion The behavioral bone-conducted thresholds to ASSR stimuli with mastoid and behind-the-ear placemen yielded no significant differences. When the stimuli intensity was 50 dB nHL, the amplitudes in single-stimulus condition were significantly higher than those to multiple-stimulus condition. There were no significant differences for BC-ASSR thresholds between single- and multiple-stimulus condition.

Objective To explore the value of ultrasonographic diagnosis of deltoid contracture (DC). Methods A total of 37 children with bilateral asymmetric shoulder were reviewed retrospectively, and 8 cases with 9 shoulders were surgically confirmed DC. The results of the ultrasonography and surgery were compared. Results The sensitivity of ultrasonographic diagnosis of DC was 88.89% and specificity was 100%. No statistically significant difference of contracture thickness measurement was found between surgery and ultrasonography. Ultrasonographic findings of DC in children included hyperechoic areas (7 cases) or hypoechoic area (1 case). Conclusion Ultrasounogrphy is an effective method for diagnosis of DC in children.

Objective To investigate the correlated clinic factors of prostecdtive efficacy and recurrence in chronic hepatitis B patients who got the combinated fully respond to Lamivudine.Methods To divide the chronic hepatitis B patients who got the combinated fully respond to Lamivudine into two groups,according to whether the curative effect was consolidated after the withdrawal of lamivudine therapy for two years.Group A was consolidated and group B was repeated.To compare the two groups correlated clinic factors.Results Consolidated ratio of prostecdtive efficacy was 64.71% in the first year,then it dropped to 55.88% in the second year.There was apparent difference between two groups which included:ages,total months of treatment,serum HBV DNA before and after treatment,ALT,time to HBeAg seroconversion and consolidation.Particularly is time stoped a medicine,the pro-s 1 Ag was negative,the HbeAg fixed amount is a 0 Ncus/ml,two all match 33 example,only 1 while stopping a medicine for 12 months relapse,two years long-term curative effect consolidation rate reaches to 97%,.But come short of twos to all match 35 example,29 HBVDNA rebound,relapse of illness,two years long-term curative effect consolidation rate reaches to 17.14% only.(P=0.0000).Conclusions To achieve the withdrawal indication after long-term antiviral therapy with nucleoside according to The Guideline of Prevention and Treatment for Chronic Hepatitis B,it still must refer to that the pro-s1Ag was negative.whether the quantitated index of HbeAg had achieved to 0Ncu/ml,otherwise,it was necessary to extend the course of treatment of antiviral therapy.The extensive course of treatment was very safe,because the ratio of mutation of YMDD and some other virus was tiny.

Objective To evaluate the results of the treatment and prevention measures for pathological dislocation of the hip following septic arthritis in the newborns. Methods Twenty cases undergone open reduction were studied restropectively. In addition, greater trochanterplasty was penformed in 15 cases, acetabularplasty in 14 cases, greater and lesser trochanterplasty in 2 cases. Rusults A successful rate of reduction achieved in 90％ of the patients; however, central reduction was achieved in only 38.8％ . 20 patients were followed-up for 6 months to 12 years. The stability and motility of the hip gradually improved in majority of the patients. The cases with severe destruction followed by absence of femoral head and neck had unsatisfactory results. Shortening deformity were found in six cases, and subluxation, dislocation, rigidity of the hip in one case each. Conclusion The greater trochanterplasty had a good result for reduction and maintaining the position. Early diagnosis and early open drainage were key measures for prevention of pathological dislocation of the hip resulting from the acute septic arthritis in the newborn.
