Objective Event related potentials (ERP), especially mismatch negativity (MMN), as index, was utilized to study the processing of Chinese tones recognized by cochlear implant (CI) users and normal hearing subjects. Methods The auditory materials were Chinese words with four tones consisting of three different oddball blocks. The ERP and MMN of CI users and normal hearing subjects were recorded and analyzed in relation to the discrimination of those tones as tested. Results The ERP and MMN of CI users and normal hearing subjects were presented. The MMN of CI users includes two negative waves: the first negative wave (MMN1) occurred approxi-mately 100 ms, and the second wave (MMN2) at 300 ms. The MMN of normal hearing subjects includes two nega-tive waves too: the first negative wave (MMN1) occurred approximately 150 ms, and the second wave (MMN2) al-so at 300 ms. The MMN1 peak latency of CI users was obviously shorter than that of normal hearing subjects and the MMN2 peak latency of CI users shorter than that of normal hearing subjects too, but the difference of MMN2 peak latency between CI users and normal hearing subjects was not as significant as that of MMN1. Conclusion In the preattentive stage, CI users could process Chinese tones as normal hearing subjects, but compared with the pro-cessing of normal hearing subjects, there are some differences in the processing of CI users.

Objective To measure the outcomes of the cochlear implantation for patients with Warrensburg syndrome in comparison with non-syndromic patients with sensorineural hearing loss. Methods 16 of 1 300 Waardenburg syndrome patients who received cochlear implants at PUMC hospital were reviewed in this papers. The authors will discuss the effects between Warrensburg syndrome and non- syndromic patients with sensorineural hearing loss by means of the Parents Evaluation of Aural-Oral Performance of Children (PEACH). Results There were no statistical difference in quiet, in noise, in overall results and in conversation on the phone between Warrensburg syndrome and non-syndromic patients. There was statistical difference between in quiet and in noise in every group. Conclusion The auditory perception and speech recognition between Warrensburg syndrome and non-syndromic patients with sensorineural hearing loss is same, and the results in quiet is better than that in noise.

Objective To investigate the value and diagnostic efficiency of the quantitative dynamic contrast enhanced-magnetic resonance imaging (DCE-MRI) and intravoxel incoherent motion (IVIM) parameters using three dimention (3D)-histogram analysis for discriminating the Gleason score (GS) of prostate cancer. Methods A total of 53 patients pathologically confirmed as prostate cancer by systemic prostate biopsy who had routine , DCE and DWI-MRI scans were retrospectively analyzed. There were 15 cases for low-risk and 38 cases for intermediate/high-risk prostate cancer. The 3D ROI of all lesions based on T2WI was achieved by image registration to get the quantitative parameters of DCE-MRI and DWI-IVIM. The parameters of DCE-MRI contains: transfer constant (Ktrans), rate constant (Kep) and extracellular-extravascular volume fraction (Ve).The DWI-IVIM related quantitative parameters were ADC, diffusion coefficient (D), diffusion coefficient related to perfusion (D*) and perfusion fraction (f). Then the histogram analysis of these quantitative parameters was performed to get the mean, median, 25th percentile, 75th percentile, Skewness and Kurtosis. Using the Spearman rank correlation analysis to evaluate the correlation of these parameters and GS of prostate cancer. The diagnostic performance of these quantitative histogram parameters related to the GS in identifying low-risk and intermediate/high-risk of prostate cancer was carried by ROC. Results The Kep and Ktrans (mean, median, 25th, 75th) of DCE-MRI were positively correlated with GS (r value was 0.346 to 0.696, P<0.05). The ADC (mean, median, 25th, 75th), D (mean, median, 25th, 75th, Skewness, Kurtosis) and D*(25th) of DWI-IVIM were correlated with GS (r value was-0.544 to 0.428, P<0.05). The DCE-MRI quantitative parameters Kep (25th) had the highest area under curve (AUC, 0.961); The ADC (median) and D (25th) had higher AUC( 0.832, 0.888) in the quantitative parameters of DWI-IVIM, the difference between Kep(25th) and ADC (median) was statistically significant (Z value was 2.212, P value was 0.027). The difference of AUC between Kep (25th) and D (25th), D (25th) and ADC (median) was not statistically significant (Z values were 1.027 and 1.398, P values were 0.162 and 0.304, respectively).Conclusion DCE and IVIM quantitative parameters (Kep, Ktrans, ADC, D) histogram analysis results are correlated with GS, and can be used for distinguishing low-risk from intermediate/high-risk prostate cancer.

OBJECTIVE: To analyze the changing features of mandarin-tone recognition in lower prelingual children with cochlear implant after mapping. METHOD: Twenty-nine children with CI were registered in this test, who were divided into two groups according to the age received the operation. They were group A whose ages were 3 to 4.5 years old, and group B whose ages were 5.0 to 6.5 years old. The time after first mapping was between 1.5 and -2.0 years. The test only included close-set phonetic recognition which was mainly used to evaluate Mandarin-tone recognition. The Phonetic Recognition List was used as the test material. RESULT: The results showed that the percentages of correct recognition were same-single-syllable tones average (63.00+/-16.75)%; bi-syllable tones average (75. 60+/-11.18)%; single-character words average (72.38+/-11.39)% in A group children and respectively, (49.46+/-13.91)%; (64.71+/-9.64)%; (55.71+/-8.59)% in B group children. The recognition scores exceeded chance level in all results and they were better in A group. Statistical analysis(t test) showed significant difference between two groups. CONCLUSION The age is one of the most influence factors about Mandarin-tone recognition after implanting in pre-lingual children with CI. It is another important factor to influence studying Chinese after operation in the children.

OBJECTIVE: To investigate the hearing and speech rehabilitation results of cochlear implantation in patients with common cavity deformity. METHOD: A retrospective study was performed on 19 patients with common cavity deformity who received multi-channel cochlear implantation from 1995 to 2010 in Peking Union Hospital, with assisted evaluation of auditory nerve pathways by intraoperative electrical evoked auditory brain stem response (EABR); matched with 19 implantees with no deformity. Paired T test was performed to compare T values, dynamic range; Rank-sum test was performed to compare scores of categories of auditory performance (CAP) and speech intelligibility rating (SIR). RESULT: The T value of common cavity inner ear malformation group (172.59 +/- 14.57) was significantly higher than that of the control group (139.63 +/- 19.45) (P < 0.05), no significant difference in dynamic range (P > 0.05); hearing and speech rehabilitation after implantation showed that the results of CAP and SIR values (5.50 +/- 0.94 and 3.00 +/- 0.82) scored significantly lower than the control group (6.90 +/- 0.77 and 3.90 +/- 0. 57) (P < 0.05), but significantly increased compared with that before. Some children appeared facial twitch at boot time caused by electrical stimulation of the facial nerve (surface pumping rate of 31.58%). CONCLUSION Common cavity is a kind of severe inner ear malformations, but to perform a comprehensive preoperative evaluation, select the appropriate surgical technique, employ personalized postoperative booting, transfer machines and long-term auditory intensive language training, the children can get varying degrees of language and hearing recovery according to the severity of deformity. On the whole, the rehabilitation outcome was significantly worse in patient with deformity than its counterpart without deformity.

OBJECTIVE: To investigate the intra-operative electrical evoked auditory brain stem response (EABR) characteristics and the hearing and speech rehabilitation effects of cochlear implantation (CI) in patients with internal auditory canal stenosis (IACS). METHOD: A retrospective study was performed on 16 patients with IACS (IACS group) matched with 16 implanted without IACS (control group), who received multi- channel CI because of pre-lingual sensorineural hearing loss. The integrity and functional status of the auditory pathway were assessed by EABR, recording waveforms, thresholds and dynamic ranges intra-operation before CI. Interviewed the implanted parents or teachers, asking them to rate the implanted hearing and speech ability according to Categories of Auditory Performance (CAP) and Speech Intelligibility Rating (SIR). Paired T test was performed to compare scores of CAP and SIR between before and 1 year after CI, while Spearman test was performed to compare correlation between EABR grades and post-operative CAP scores. RESULT: Among the IACS group, 2 cases weren't recorded typical EABR waveforms and without auditory response 1 year after a successful CI. The EABR waveforms in the IACS group were poorer than that in the control group, their EABR thresholds higher than the control group, and their EABR dynamic ranges less than the control group. The hearing and speech rehabilitation after CI showed that the results of CAP and SIR values (3.47 +/- 1.09 and 1.62 +/- 0.50) scored significantly lower than the control group (5.06 +/- 0.79 and 2.59 +/- 0.58) (P < 0.05), but significantly increased compared with pre-operation. Intra-operative EABR grades and post-operative CAP scores showed significant correlation (r = 0.78 , P < 0.05). CONCLUSION Intra-operative EABR can accurately monitor the integrity and functional status of the auditory pathway, be of important clinical value in predicting whether patients can acquire auditory responses with the aid of CI. CI can help patients with IACS to improve the ability of hearing and speech with EABR to screen out compatible implanted.

OBJECTIVE: To evaluate the pathological position of auditory neuropathy and investigate the hearing and speech rehabilitation results of cochlear implantation in patients with auditory neuropathy. METHOD: In our hospital, among the patients received cochlear implantation, 8 cases with auditory neuropathy were selected, and 8 cases of non-auditory neuropathy patients with profound deafness were selected as matched control group with the background close to the study group. The preoperative hearing data of these two groups were retrospectively analyzed. During operation, the homemade stimulation electrodes were inserted to test the electric evoked auditory brainstem response(EABR) for assessing the auditory pathway; EABR and neural response telemetry(NRT) were tested after implantation, and T, C value were acquired 1 month later. CAP, SIR and speech recognition rate were used to assess hearing and speech rehabilitation effect 12 months after booting. RESULT: Intra-operative EABR wave can be derived in 8 cases of auditory neuropathy, but the wave pattern exhibited variations compared with normal wave. It needed increased stimulation or adjusted parameters, with variable V latency. After cochlear implantation, the waveforms of NRT and EABR were similar between the two groups, and the post-operative V waveform was close to the intra-operative EABR. 8 pairs of patients can present listening response after booting. There was no statistically significant difference in T, C value, CAP (6.50 +/- 0.94 and 6.90 +/- 0.77) and speech recognition rate (85.00% +/- 11.66% and 89.50% +/- 9.02%) between the auditory neuropathy group and the control group 1 year after booting. CONCLUSION Pre-operative EABR can be used as an effective tool to assess the auditory pathway of auditory neuropathy patients, improving the pre-operative examination and helping with selecting the suitable cochlear implant patient. Cochlear implantation can help patients with auditory neuropathy to improve hearing and speech.

The auditory nervous system has a rapid development period after birth, if there lack enough sensory(auditory) stimulation during this period, there should be a serious and negative impact on the growth and development of auditory center. In the auditory deprivation persist in the critical period, the auditory and visual cortex should be in cross-model reorganization and reorientation of cortical function. Cochlear implantation, especially intervention in the younger age, could excite the auditory cortex, and continuous stimulation to the cerebral cortex can promote the adaptation and reconstruction of auditory function. Speech and language skills can be developed by the synergistic effect of multiple sensory modalities.

This paper reviews the clinical researches on acupuncture and moxibustion and Tuina therapy for hemiplegia, due to cerebral apoplexy. It is found that acupuncture and Tuina therapy mainly includes acupuncture, moxibustion, massage, electroacupuncture, as well as the combination of acupuncture and Chinese medicine, acupuncture and massage therapy or the combination of modern rehabilitation technics. The researches showed that all treatments have good clinical effect and few adverse reactions. However, most of the researches focus on self-control, and lacks comparability. There stilllacks strict RCT and unified standard of operation scheme. Besides, the researches on the mechanism should be strengthened.

Objective:To explore the consistency of MRI-based ovarian-adnexal report and data system (O-RADS) score and its diagnostic value for ovarian adnexal masses.Methods:The MRI data of 309 patients with ovarian adnexal masses confirmed by pathology were retrospectively collected from January 2017 to August 2021 in the Second Affiliated Hospital of Soochow University, including 327 lesions consisted of 250 benign lesions, 21 borderline lesions, and 56 malignant lesions confirmed by pathology. Borderline and malignant lesions were classified into the malignant group ( n=77) and benign lesions were classified as benign group ( n=250). Two radiologists scored all lesions according to the MRI-based O-RADS, and scored again after 6 months. The proportion of borderline/malignant lesions in each MRI-based O-RADS score was calculated. The weighted Kappa test was used to assess the intra-reader and inter-reader consistency of the image interpretation results. The receiver operating characteristic (ROC) curve analysis was used to evaluate the diagnostic efficacy of MRI-based O-RADS classification for distinguishing benign and malignant ovarian adnexal masses. Results:The weighted Kappa value of the MRI-based O-RADS score between the two radiologists was 0.810 (95%CI 0.764-0.855), and the weighted Kappa values of the two radiologists′ scores at different times were 0.848 (95%CI 0.806-0.889) and 0.875 (95%CI 0.835-0.914), respectively. The borderline/malignant lesions accounted for 0/16, 0.8% (1/127), 10.1% (10/99), 76.0% (57/75), 9/10 and 0/17, 0 (0/122), 8.0% (8/100), 76.2% (48/63), and 84.0% (21/25) of the lesions in the two radiologists based on the MRI O-RADS score of 1, 2, 3, 4, and 5, respectively. When adopting O-RADS score>3 as a cut-off value, the area under the ROC curve of the two radiologists for distinguishing benign and malignant ovarian adnexal masses was 0.928 (95%CI 0.895-0.954) and 0.942 (95%CI 0.911-0.965), respectively. The sensitivity was 0.857 and 0.896, the specificity was 0.924 and 0.924, and the accuracy was 0.908 and 0.917 respectively.Conclusion:The MRI-based O-RADS yields high diagnostic efficiency in the evaluation of benign and malignant ovarian adnexal masses, and the intra-reader and inter-reader consistency of the image interpretation is strong.
