OBJECTIVE:
To investigate the current situation of early diagnosis and intervention in 0-9 months old infants with hearing loss and analysis factors that will affect early diagnosis and intervention.
METHOD:
One hundred and eighty-six infants referred to the West China hospital from February 2014 to September 2014 were included. All 186 children were referred due to the fact that either they failed infant hearing screening or outer ear malformation. Early diagnosis and/or intervention were performed on those 186 children and their records of early diagnosis and intervention were analyzed.
RESULT:
Among the 186 infants, 167 (89.8%) were diagnosed with an average age at (4.0 ± 1.4) months. Among the 167 infants with final diagnosis, there were 31 (18.6%) infants diagnosed as conductive hearing loss (CHL), and 99 cases (59.3%) diagnosed as sensorineural hearing loss (SNHL), among whom, there were 75 (44.9%) bilateral SNHL and 24 (14.4%) unilateral SNHL. There were 2 cases (1.20%) with SNHL on one side and atresia on the other side. 5 (2.99%) of all conductive hearing loss cases with unilateral atresia and 2 cases with auditory neuropathy (AN) were found. 33 infants (19.8%) were found to have normal hearing. 30.7% (23/75) infants diagnosed as bilateral SNHL and 8.3% (2/24) infants diagnosed as unilateral SNHL were fitted with hearing aids. The fitting rate in infants with bilateral SNHL with mild, moderate, severe to profound degrees were 0 (0/23), 24.0% (6/25), 66.7% (6/9), 61.1% (11/18) respectively. The average intervention age was (5.0 ± 2.1) months.
CONCLUSION
Although the early diagnosis and intervention situation in this study are very close to international standard, there are still infants without final diagnosis and infants with hearing loss without hearing aid fitting. Further studies and efforts to promote early diagnosis and intervention in infants with hearing loss are needed.

Objective To investigate the accuracy of real-time continuous glucose monitoring(RT-CGM)system in the type 2 diabetes mellitus(T2DM). Methods A total of 318 subjects hospitalized between 2013 May to 2014 August were recruited. Each subject received a RT-CGM system. In order to calibrate the interstitial glucose level, finger-stick blood glucose were measured at least four times every day. Patients were divided into three groups according to their finger-stick blood glucose level:≤6.99 mmol/L, 7.0-10.0 mmol/L and≥10.01 mmol/L. Pearson correlation was used to analyze the relationship between the finger-stick glucose and interstitial glucose gained from RT-CGM. Clarke error grid analysis was used to analyze the accuracy of RT-CGM. Results (1)A total of 2, 815 glucose meter values from finger-stick were com?paired with glucose from RT-CGM. A positive relationship(r=0.847)were found between CGM and finger-stick blood glu?cose. The correlation was closer with higher finger-stick blood glucose levels(r=0.457, 0.648 and 0.852 respectively in≤6.99 mmol/L group, 7.0-10.0 mmol/L group and≥10.01 mmol/L group. P<0.001).(2)The Clarke error grid analysis re?vealed that 76.69%of the readings from RT-CGM were clinical perfect (zone A), 20.28%were acceptable (zone B), 3.03%were unacceptable (zone C-E). Clinical perfect rate was lower when the finger-stick glucose≤6.99 mmol/L , compared with that when it is between 7.0-10.0 or≥10.01 mmol/L group(73.12%vs 78.63%&79.28%,P<0.05), there was no significant difference between group of 7.0-10.0 mmol/L with group≥10.01 mmol/L (P>0.05). Conclusion RT-CGM provides accu?rate blood glucose values to guide the treatment of diabetes, and the accuracy is more reliable in high glucose environment.

Objective To report the clinical, myopathological and genetic features in myofibrillar myopathy (MFM) with numerous cytoplasmatic-spheroid bodies. Methods Ten patients in 5 successive generations began to present progressive proximal limbs weakness at 35 to 40 years old. Additionally, 4 cases manifested diarrhea and 6 cases accompanied with cardiorespiratory symptoms. An open biopsy was performed on the proband. In addition to histological, enzymhistochemical staining and ultrastructural examination, immunohistochemical staining with antibody against tau, desmin, ubiquitin, dysferlin, dystrophin-C', dystrophin-N' and dystrophin-R were done. All the exons of the MYOT, CRYAB, DESMIN, LDB3, LMNA, SEPNI gene and the FLNC exon 48 were analysed. Results Cytoplasmatic bodies and spheroid bodies were found in the fibers. The deposited material were positive for tau, desmin, ubiquitin, dysferlin and dystrophin-R, dystrophin-C'. Electron microscope showed granular dense Z-disc material in the inclusions which were surrounded by thin filament. There was no mutation in the above exons of the 7 candidate genes. Conclusions Myofibrillar myopathy involves multiple system impairment. Cytoplasmatic and spheroid bodies contain microtubule and membrane associated protein. The disease might be induced by some unknown genetic abnormities.

Objective To report filaminopathy with novel insertion mutation in a Chinese family.Methods Total 19 patients from successive 5 generations involved in an autosomal dominant family. The detailed clinical manifestations had been described (Chinese Journal of Neurology, 2008, 41:751-755).The filamin C gene sequencing was performed in 3 patients, 5 family members without symptoms and 50 normal persons. The amplified fragments of the exon 18 in filamin C gene were cloned into pBluesripts vectors, then sequenced and identified with capillary electrophoresis. Results 18-nucleotide deletion and 6-nucleotide insertion were identified in the exon 18 of filamin C gene. The mutation caused the disturbance of the seventh immunoglobulin-like domain in filamin C, leading to the instability of dimmers of filamin C.Another 2 patients in the family had same mutation while 5 family members without symptoms and 50 normal controls were normal. Conclusion The novel nucleotide deletion-insertion in exon 18 of filamin C gene causes filaminopathy. This disease can appear in non-Nordic race.
