OBJECTIVE: To investigate the lexical tone perception and quality of life of Nurotron cochlear implant users. METHOD: Forty-nine adult cochlear implant users participated in this study. Mandarin tone identification test developed by Beijing Institute of Otolaryngology was used to evaluate the tone perception. Nijmegen cochlear im plantation questionnaire (NCIQ) was administered to quantify the quality of life. RESULT: (1) The average scores of tone perception in quiet was 67.26%. The tone perception rates under quiet condition for all cochlear implant recipients were higher than the opportunity level. (2) The average scores of tone perception under noisy condition was 51.92%. Exc ept for two recipients, the tone perception rates under noise condition for the rest recipients were better than chance. (3) The confusion patterns of tone recognition showed that Tone 3 was the easiest tone to perceive. (4) The postimplant scores for the total , basic sound perception, advanced sound perception, speech pro duction, self-esteem, activity and social interactions of NCIQ were 55.4, 72.4, 54.0, 63.4, 50.7, 47.3 and 44.7, respectively. CONCLUSION The Nurotron cochlear implant users had the ability for lexical tone perception and had an improvement in quality of life after cochlear implantation.

OBJECTIVE: To evaluate preverbal communication skills in Chinese deaf children with cochlear implants, and to provide a basis for designing the habilitation program and establish a precursor for outcomes of habilitation. METHOD: Thirty children with cochlear implants participated in this study with a mean age of 32 months. They all had used the cochlear implant system within 12 months with a mean of 5. 8 months. All the children were diagnosed with prelingual profound hearing loss before cochlear implantation. Tait video analysis was used to analyze and assess the preverbal communication skills including turn-taking, autonomy, eye contact and auditory awareness. All statistical analyses were performed using the SPSS 13.0 statistical software package with a criterion of statistical significance set at P < 0.05. RESULT: The skill of turn-taking developed quickly within 12 months after cochlear implantation. The vocal turn developed in a similar pattern, and the score of gesture turn decreased slowly. The skills of autonomy and appropriate eye contact showed small changes over time at a lower level. The score of auditory awareness increased gradually after surgery. CONCLUSION Children established a vocal/auditory mode of early communicative behavior following cochlear implantation. They preferred to communicate with others in a more vocal style. Video analysis is a useful tool to assess preverbal communication skills in deaf children with cochlear implants in China.

Background:The morbidity of ulcerative colitis(UC)is high,and is easily recurrent.A number of systematic review/meta-analysis have explored the efficacy and safety of fecal microbiota transplantation(FMT)in the treatment of UC with varying conclusions,however,the quality of these studies has not yet been adequately assessed.Aims:To overview the systematic review/meta-analysis of FMT for UC.Methods:Systematic review/meta-analysis of FMT in the treatment of UC were retrieved from PubMed,Cochrane Library,Embase,Web of Science,CNKI,CBM,Wanfang,VIP and other databases from the date of database establishment to May 2023,while gray literatures were searched and experts were consulted.Literature screening and extract information were performed by two researchers.The PRISMA checklist,AMSTAR-2 tool was used to assess the reporting quality and methodological quality,respectively,as well as to grade the quality of evidence for outcome measurements based on the GRADE system.Results:Seventeen systematic review/meta-analysis were finally included.The original studies included randomized controlled trials and observational studies.Most of the studies drew positive conclusions about the efficacy and safety of FMT in the treatment of UC.The PRISMA checklist score was 12.5-22.5,and the mean score was 17.68.Three studies reported relative completeness;ten had some deficiencies;and four had relatively serious report deficiencies.AMSTAR-2 tool showed that two were of intermediate quality,three were of low quality,and twelve were of very low quality.GRADE system ratings showed that six of the eight outcome measurements were of intermediate quality and two were of low quality.Conclusions:FMT may be a safe and effective treatment for UC,but the quality of the current evidence is low and users of clinical evidence need to treat the above evidence with caution.

OBJECTIVE: To investigate the law of auditory remodeling by studying the Cortical Auditory Evoked Potential in a group of post-lingually deaf adults in the early stage of the cochlear implant use. METHOD: Ten post-lingually deaf adults implanted with PULSAR ci 100 of Medel device ranged from 19 to 52 years old with duration of deafness from 3 months to 23 years.were involved. Their P1-N1-P2 responses to /ba/ at around 60-70 dB SPi and open-set speech recognition scores of mono-syllabic words were recorded at 1. 3 and 6 months after the switch-on of cochlear implants. RESULT: Six out of 10 typical waveforms of Pl-N1-P2 were obtained. The other I were with atypical waveforms. The group with atypical waveform was characterized by long duration and early onset of deafness. There was no significant difference regarding either the amplitude or the latency of each peak at the 3 data collection time points. There was significant difference among the 3 data collection time points about the speech recognition scores with the highest score at the 6th month of switch on. There was no significant correlation between the peak of the CAEP and speech recognition score. CONCLUSION In the first 6 months of cochlear implant use in the post-lingually deaf adults, the duration and the onset age of deafness played important role in respect of the presence and waveform morphology of the CAEPs. It needs at least 6 months for the central auditory system to make use of the audio input from the cochlear implant.
