Objective To explore the effects of interleukin- 1?(IL-1?)on the biological activity of human periodontal ligament(PDL) cells in vitro. Methods Human PDL cells were cultured in DMEM medium containing IL-1?(0.1,0.5,1,5 and 10ng/ml) for 1,2,3,4 and 5 days, respectively. The proliferation of PDL cells was measured by MTT assay at the first, second, third, fourth and fifth days after IL-1? treatment, respectively. Fibronectin level in the medium was determined by ELISA at the fourth days after 10ng/ml IL-1? treatment, and alkaline phosphatase(ALP) activity was measured by enzyme kinetic method. Results IL-1? inhibited the growth of human PDL cells in a dose-dependent manner, and its lowest effective concentration was 1ng/ml(P

Objective The purpose of this study is to compare the most comfortable levels and neural re-sponse imaging threshold between children of cochlear implants with large vestibular aqueduct syndrome and normal inner ears. Methods Thirty-eight implanted children participated in this study and were divided into two groups. Group A consisted of 32 patients with normal inner ears and group B 6 patients with radiographically proven large vestibular aqueduct syndrome. All of the patients were the recipients of the cochlear implants by Advanced Bionics. The initial time for the first programming session was approximately one month after surgery. The psychophysical tests included M- level tests. Programming techniques used in the test were suitable for the age of patients. Sound-Wave 1.4 software was used to test tNRI. Results Using the rank sum test, M-level and tNRI of electrode 3,7,11 and 15 did not differ significantly between group A and B(P>0. 05). Conclusion The parameters of mapping are not significantly different between the implanted children with large vestibular aqueduct syndrome and normal inner ear. The management and procedures of mapping used to the subjects with normal inner ear can be applied to the children with large vestibular aqueduct syndrome.

OBJECTIVE: This article evaluates the auditory and speech perception outcomes of sensorneural hearing loss with cerebral white matter abnormalities after cochlear implantation. METHOD: A retrospective analysis was performed on the cochlear implantatees with cerebral white matter abnormalities by using the categories of auditory performance and speech intelligibility rating, and compared with the non-syndrome patients with sensorineural hearing loss. Paired t-test was used for statistical analysis. RESULT: There was statistical difference between normal group and white matter changes group with sensorineural hearing loss after 6 month. No statistical difference was found after 12 month and 24 month. CONCLUSION In the short term, the cochlear implant can be performed safely in patients with white matter changes. After a formal rehabilitation training,no significant difference in auditory or language ability was found between normal group and white matter changes group with sensorineural hearing loss.

OBJECTIVE: Through the use of the categories of auditory performance (CAP-II), the speech, spatial and qualities of hearing scale-parents' version (SSQ-P), children using hearing implants quality of life (CuHI-QoL) in patients with prelingual hearing impairment to compare the rehabilitation effect between preoperative and postoperative auditory performance, speech behavior and quality of life and at the same time to figure out dose rehabilitation effect connected to age. METHOD: Mainly used classification method to compare the audotory performance, speech behavior and quality of life of 50 patients before and after 2.5 years after the implantation. At the same time these 50 patients are divided on the basis of the age received the surgery, A group received the surgery before 6(1.0-5.9) years old and group B received the therapy after this age (6.0-10.9). Their auditory performance, speech behavior and quality of life were all evaluated. RESULT: There were statistical difference between two kinds of classification method of CAP-II. In the study of SSQ-P and CuHI-QoL, there was no statistical difference in well-being and happiness before and 3 years after the implant, also there was no statistical difference in parental stress between two age groups. In addition to the above two, the rest all have statistical significance. CONCLUSION After the implant, postoperative auditory performance, speech behavior and quality of life all had improved and the smaller the age, the better the performance.
