Objective To evaluate the family and individual quality of life for the prelingually deaf adolescents with cochlear implants and compare the influence of preoperative communication mode.Methods A retrospective study was conducted in 21 prelingually profoundly deaf adolescents divided into the nonverbal group and oral group according to preoperative communication modes.The scores of the children using hearing implants quality of life (CuHI Qol) and nijmegen cochlear implant questionnaire (NCIQ) were collected and compared statistically between the two groups.Results The postoperative scores of CuHI Qol (51.71±8.9) in 21 patients were significantly higher than those before operation (42.14±6.04,P<0.001), and no significant differences were observed in the family influence between the two groups while the scores of oral group were significantly higher than the nonverbal group in parents' expectation and quality of life(P<0.05).The NCIQ scores of the oral group were significantly higher than nonverbal group(P<0.05) in the following subdomains : advanced sound perception, speech production, social interactions and there was no statistical difference in basic sound perception, self-esteem and activities.Conclusion The quality of life of prelingually deafened adolescents with cochlear implants can be improved obviously and patients with oral communication mode before operation have better quality of life.

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 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

AIM To investigate the significance of CGRP and ET in the coronary syndrome and the significance of their changes in the incidence of the acute coronary syndrome.Methods Group with UA group ( n =30), AMI group ( n =28), control group ( n =25) were established.In control group blood sample take on an empty stomach in the morning ,while group with AMI on hospitalization and after one week, group with UA at angina pectoris attack and after remission. The concentration of plasm CGRP and ET were measured .Results The plasm CGRP concentration in group with AMI was higher than that in group with UA and that in control group ,the plasm ET elevated markedly, while the rate of CGRP/ET decreased; Compared with that in the remission period of the acute coronary syndrome ,The plasm CGRP elevated, the plasm ET elevated markedly, while the rate of CGRP/ET decreased.Among defferent acute coronary syndrome ,the plasm CRGP and ET concentrantion was highest in AMI group,higher in group with accelerated UA, high in group with initial attack UA;the rate of CGRP/ET was highest in group with initial UA,higher in group with accelerated UA,high in group with AMI.Conclusions The changes of plasm CGRP and ET concentration are well correlated with the extent of coronary lesion, the level of plasm CGRP and ET and the imbanlance of thier receptor play an important role in the pathogenesis and development of acute coronary syndrome.

Objective To evaluate the ability of 64-slice spiral CT(64-MSCT) in demonstrating the coronary collateral circulation(CCC).Methods Patients undergoing 64- MSCT coronary angiography with relatively good image quality from August 2005 to April 2007 were entered into the study according to following requirements: patients underwent a traditional coronary artery angiography (CAG) after the coronary CT imaging; the CAG showed there was stenosis greater than 90% in at least one major coronary artery.The CCCs were assessed in CAG by the Rentrop grading, and the CAG served as the gold standard to determine the accuracy of 64-MSCT angiography in detecting collateral circulations.All CCCs were grouped angiographieally into three groups of CC0, CC1 ,and CC2 by Werner collateral collection(CC) grading.In the 64-MSCT coronary angiography imaging, a new grading(MSCT-CC) was used to evaluate CCCs.The consistency between these two grading standards was analyzed by Kappa test.Resalts A total of 97 patients were entered into the study, among whom at least one CCC was found by CAG in 37 patients and at least one CCC was detected by 64-MSCT angiography.Taken the CAG results as the reference standard, the sensitivity and specificity of the 64-MSCT angiography in detecting patients with the CCCs were 89.2% (33/37) and 93.8% (60/64) respectively.The sensitivity of the 64-MSCT angiography detecting the CCCs was 75.8% (47/62). All the CCCs detected by CAG and 64-MSCT angiography were grouped into three groups according to Werner grading: 4 in CC0 group, 24 in CC1 group and 19 in CC2 group.The CCCs were grouped into three groups according to MSCT-CC: 7 in MSCT-CC0 group, 22 in MSCT-CC1 group and 18 in MSCT-CC3 group.The consistency of the two grading criteria was relatively high (Kappa = 0.857, P < 0.01).Conclusion 64-MSCT angiography can accurately evaluate the coronary collateral circulation.

Results In 8 patients with pulmonary embolism,43 vessels were involved with pulmonary embolism.The presence of pulmonary embolism on CT was seen as a total occlusion,partial filling defect,mural filling defect et al;dilated of pulmonary artery trunk;all signs with deceleration of pulmonary blood or “mosaic sign”. 5 patients were reexamined with this method.The emboli dissoved partly or entirely.Conclusion Multiple spiral CT angiography is a noninvasive and effective method for examining pulmonary embolism.

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.
