Objective To investigate the characteristics of common deafness genes mutation from 222 sensori-neural hearing loss patients in Guangxi province.Methods A deafness-related gene mutations detection kit was used to detect 15 mutation sites in four deafness-associated genes.A total of 222 hearing impaired patients,who were selected from January 2015 to April 2016,were tested.The samples that could not be diagnosed with DNA mi-croarray were subjected to PCR and sequenced to detect other mutations.Results Among the 222 patients with sen-sorineural deafness,the total mutation rate was 10.36% (23/222),including GJB2 235delC homozygous in 3 cases (1.35%),235delC single heterozygous mutation in 8 cases (3.60%),35delG single heterozygous mutation in 2 cases (0.90%),GJB2 235delC and 109 A>G mutations in 2 cases (0.90%),SLC26A4 1229C>T homozygous in 2 case (0.90%),IVS7-2 A>G heterozygous mutation in 2 cases (0.90%);IVS7-2A>G,IVS11+47T>C and 1548 insC mutations in 2 cases (0.90%);GJB3 538C>T heterozygous mutation in 1 cases (0.45%);Mitochondrial 12S rRNA gene heterogeneous mutations in 1 case (0.45%).One of them carry both two mutations:GJB2 235 del C and SLC26A4 1226 G>A.Conclusion The results indicate that GJB2 and SLC26A4 were the main genes in this study,and in Guangxi province the mutation rate is significantly lower than the national average level.3 new muta-tions (SLC26A4 IVS11+47T ! C,1548insC and GJB2 109A>G)were found.There may be some rare mutations among sites or genes caused deafness in Guangxi.

OBJECTIVE:
To investigate the mutation characteristics of common deafness gene from 127 non-syndromic hearing loss patients in Guangxi province.
METHOD:
Deafness-related gene mutations detection kit was used to detect 15 mutation sites in four deafness-associated genes, and a total of 127 hearing impaired patients were tested. The samples that could not be diagnosed with DNA microarray were subjected to PCR and sequenced to detect other mutations.
RESULT
Among the 127 patients with non-syndromic deafness, the total mutation rate is 8.66% (11/127), including GJB2 235delC homozygous in 3 cases (2.36%), 235delC single heterozygous mutation in 2 cases (1.57%), GJB2 235delC and 109 A > G mutations in 2 cases (1.57%); SLC26A4 1229C > T homozygous in 1 case (0.79%), IVS7-2A > G, IVS11 + 47T > C and 15448insC mutaion in 2 cases (1.57%); mitochondrial 12S rRNA gene mutations were not detected. The result indicates that GJB2 and SLC26A4 were the main genes in this study, and the mutation rate is significantly lower than the national average level. Three new mutations (SLC26A4 IVS11 + 47T > C,1548insC and GJB2 109A > G) were found. There may be rare mutations among sites or genes associated with deafness in Guangxi.

OBJECTIVE:
To explore the genetic basis for a Chinese pedigree affected with non-syndromic hearing loss (NSHL).
METHODS:
Commercialized gene chip was applied to detect common mutations associated with congenital deafness. Whole exome sequencing was carried out for patients for whom gene chip yielded a negative result. Candidate variants were verified by Sanger sequencing.
RESULTS:
Two patients from the pedigree were discovered to carry compound heterozygous variants of the TRIOBP gene, namely c.3299C>A and c.5185-2A>G. Their parents had normal hearing and were both heterozygous carriers of the above variants. Both variants had co-segregated with the disease phenotype in the pedigree and were unreported previously.
CONCLUSION
Pathogenic variants of the TRIOBP gene comprise an important factor for NSHL. The novel c.5185-2A>G and c.3299C>A variants discovered in this study have enriched the mutational spectrum of the TRIOBP gene and enabled molecular diagnosis and genetic counseling for the family.

OBJECTIVE:
To observe the effect of acupoint application of gel plaster on quality of sleep and life in patients with insomnia.
METHODS:
A total of 63 patients with insomnia were randomized into a gel plaster group (32 cases, 1 case dropped off) and a placebo plaster group (31 cases). Acupoint application of gel plaster was applied at Yintang (GV 29) and Yongquan (KI 1) in the gel plaster group, placebo plaster was applied at the same acupoints in the placebo plaster group. The treatment was given from bedtime to early moming of the next day, 5 days were as one course, with 2-day interval, totally 4 courses were required in the both groups. Pittsburgh sleep quality index (PSQI), Epworth sleepiness scale (ESS) and Flinders fatigue scale were used to evaluate the sleep quality and fatigue level of the patients in the both groups before and after treatment and at 2 weeks of follow-up. The variations of insomnia TCM syndrome score and the 36-item short-form health survey (SF-36) score before and after treatment were observed.
RESULTS:
Compared before treatment, the scores of PSQI, ESS and FFS after treatment and at follow-up were decreased in the both groups (
CONCLUSION
Acupoint application of gel plaster can effectively improve the quality of sleep and life in patients with insomnia.
