OBJECTIVE:
To assess the clinical effeetiveness of prelingually deaf children after cochlear implantation at different ages so as to provide reasonable expectations for the patients and guidance for the clinical treatment.
METHOD:
Electronic databases PubMed, YZ365. COM, WANFANG DATA, CMJD, CHKD, CNKI were searched using relevant keywords. Extracted data included author, year of publication, diagnosis, et al. Reported treatment outcomes were clustered into speech discrimination and hearing abilities. Meta-analyses were performed on studies with numerical results using random or fixed effects model.
RESULT:
There were eight randomized control studies including 442 patients. Comparing speech perception of prelingually deaf children after cochlear implantation younger than three years old (experimental group) and 3-6 years old (control group), three and six months after operation showed that experimental group performed significantly worse than control group; 12 months after operation showed that experimental group performed significantly better than control group. Comparing hearing abilities, three and six months after operation showed that experimental group performed significantly worse than control group; 12 months after operation showed showed that experimental group performed significantly better than control group. Comparing speech perception of younger or older than 4. 5 years old children showed that after 1.5-2 years of operation children implanted younger than 4.5 years of age performed significantly better than children implanted older than 4.5 years old. Comparing speech perception of 7-12 years old children showed that after 3, 6, 12 months of operation patients of 7-12 years old performed significantly better than those children older than 12 years old. Comparing speech perception of implantation younger or older than 18 years old (7-14 yeas old was group A, > 14-18 yeas old was group B, older than 18 yeas old was group C) showed that after one and four years of operation A > B > C, and there were significant differences among them. Comparing warble tone threshold average (WTA) showed that after one year of operation A < B < C, and there were significant differences among them. However, after four years of operation, there was no significant difference among them.
CONCLUSION
Prelinguistically deafened patients younger than three years old with cochlear implantation, insisting on scienctific rehabilitation training for a long period of time can receive the optimal recovery effect. The older patients are suggested as early as possible receiving cochlear implantation. The longer they are implanted, the better results they will receive. Moreover, the younger age they are implanted, the faster postoperative language progress they will receive. Further controlled studies with longer follow-up periods and more person included may make the effectiveness of cochlear implantaion more reliable.

OBJECTIVE:
Assess and compare the clinical efficacy and safety of cochlear implantation in deaf patients with inner ear malformation and in the ones with normal inner ear structure, so that to clarify whether it is effective to restore hearing for the deaf patients with inner ear malformation.
METHOD:
The literature with relevant key words were retrieved in the databases including PubMed, YZ365. com, WANFANG data, CMJD, CHKD and CNKI with language limited to Chinese and English. Extracted data included author, year of publication, diagnosis, treatment, et al. The clinical efficacy of cochlear implantation was assessed by the complications, electrode impedance, behavior T-level, hearing abilities and speech discrimination. Meta-analysis was performed using random or fixed effects model according to the heterogeneity of data.
RESULT:
There were 11 randomized control studies involving 655 patients included in this study. There was no statistically significant difference among the deaf patients in mixed inner ear-malformation group, Mondini group and large vestibular aqueduct syndrome group in the aspects of postoperative complications, electrode impedance, behavior T-level, hearing abilities and speech discrimination.
CONCLUSION
Cochlear implantation could be the way of treatment and rehabilitation for deaf patients with inner ear malformation. Further controlled studies with longer follow-up periods and more multiracial cases included may help to evaluate the efficacy of cochlear implantation for deaf patients with inner ear malformation more reliably.

Objective:To investigate the relationship between herpesviridae and malignant or benign laryngeal diseases.Method:128 paraffin-embedded laryngeal squamous cell carcinoma and laryngeal epithelium hyperplastic lesions were detected by polymerase chain reaction (PCR) and PCR-ISH for herpesviridae. Result:HSV-1 was detected in 10 cases by PCR,among them 3 were laryngeal squamous cell carcinoma (LSCC),1 was carcinoma in situ(CIS),4 were laryngeal polyps and 2 were laryngeal keratosis. Except 1 LSCC and 1 CIS, 8 of 10 cases were positive while detected by PCR-ISH. In benign diseases, signals were shown from basal layer to superficial cell; in malignant lesions, the signals were scattered in the diseases.Conclusion:Most of laryngeal diseases were not related to herpesviridae, but HSV-1 may acts as initiator in the development of a few cases.

Objective:To explore whether the phospholipidoproteinaceous material deposit within the alveoli by a high-ifeld 3T MRI has signal characters and its application for diagnosing pulmonary alveolar proteinosis.Methods:A total of 11 patients with pulmonary alveolar proteinosis previously diagnosed by ifberoptic bronchoscope lung biopsy underwent 64-slice helical CT scans and 3T MRI scans, and the CT scans and the MRI scans were compared.
Results:hTe phospholipidoproteinaceous material deposit within the alveoli presented longer or equal T1 relaxation time and longer T2 relaxation time, without characters of fatty or deposits of protein-like substance signals and enhancement. The distribution, form, number and size of the lesions at T2WI were almost the same as those at CT, the lesions were irregular in morphology, and there was a clear boundary between the lesions and the adjacent normal lung tissues. Dynamic contrast-enhanced MRI showed thickened pulmonary arteriolae and venulae in the lesions with more obviously thickened pulmonary venulae, which were in conformity with the pulmonary artery and venule enhancement. CT scan in 1 out of the 11 cases showed lesions in both lungs mainly consisted of stripe-shaped and reticular structures, and no obvious sign of pulmonary alveolar proteinosis residue was found. MRI scan detected alveolar proteinosis that failed to be shown by CT scan.
Conclusion:3T MRI T2WI can easily detect the lesions of long T2 signals formed by the lipoproteinaceous material deposit within the alveoli. In the lesions, geographic appearance was presented, and the crazy paving pattern was dimly visualized. MRI can relfect the morphological characters of PAP like CT and it is slightly better compared with CT in such aspects as evaluating the theraputic effect of lung lavage. As supplement to CT, high-field 3T MRI can serve as an important examination for lung diseases.
