COVID-19 Resulting in Potential Hearing Damage of Rodents

Objectives To find out the association between the sensorineural hearing loss and coronavirus disease 2019(COVID-19),the expression of ACE2 and TMPRSS2 in hamsters and mice was detected.Design Using the public data from the National Center for Biotechnology Information and the Global Initiative on Sharing All Influenza Data,the expression of ACE2 and TMPRSS2 at the transcriptomic,DNA,and protein levels of ACE2 in the brain,inner ear,and muscle from the golden Syrian hamsters(Mesocricetus auratus)and mice(Mus musculus)was assessed.Results We identified ACE2 and TMPRSS2 expressed at different levels in the inner ear and brain at DNA and transcriptomic levels of both mice and hamsters.The protein expression from the brain and inner ear showed a similar pattern,while the expression of ACE2 from the inner ear was relatively higher than that from the muscle.Conclusion Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)shows genetic potential to infect the hearing system of rodents and lead to sudden sensorineural hearing loss that can be used as a characteristic to detect asymptomatic patients of COVID-19.

The effect of acupuncture at “Jǐng Jiājǐ”(颈夹脊) on auditory brainstem response threshold of guinea pigs with sensorineural hearing loss

Objective To explore the effect of acupuncture at ＂Jing Jiaji＂ （颈夹背） on sudden hearing loss by observing the changes of the threshold of auditory brainstem response （ABR） of deaf guinea pigs. Methods Sixty healthy guinea pigs were selected, with computer randomization, 20 were randomly divided into a normal control group （group A）, while the rest were randomly and equally divided into a model group （group B） and an acupuncture group （group C） when turned deaf after gentamycin sulfate and furosemide were administered. No treatment was administered for either the group A or the group B, while acupuncture at ＂Jing Jiaji＂ was given for the group C for 30 days. The ABR thresholds of each group were observed and recorded separately after the treatment for 15 days and 30 days. Results The ABR threshold in the group C was lower than that in the group B after the treatment of 15 days （P〈O.05）. After the treatment of 30 days, the ABR threshold in the group C was obviously lower than that in the group B （P〈0.01）, and was obviously lower than that before acupuncture （P〈0.01）. Conclusion Acupuncture at ＂Jing Jiaji＂ has definite effect on improving the hearing of deaf guinea pigs.

Clinical observation on the different frequency hearing damages in sudden deafness treated by electroacupuncture combined with western medicine comprehensive therapy

Objective To compare the difference in the clinical efficacy on the different frequency hearing damages for the patients with sudden deafness between the comprehensive therapy of electroacupuncture and western medicine and the simple western medicine comprehensive therapy. Methods Fifty-eight cases were randomized into an acupuncture plus medication group （28 cases, 32 damaged ears） and a western medicine group （30 cases, 34 damaged ears）. In the acupuncture plus medication group, the comprehensive therapy of electroacupuncture and western medicine was used. The main points were ěrmén （耳门 TE 21）, Tīnggōng （听宫 SI 19）, Tīnghuì （听会 GB 2）, Yìfēng （翳风 TE 17）, etc. The western medicine therapy was the comprehensive treatment with vasodilators, the medicines for promoting nerve function and releasing inner ear edema and hyperbaric oxygen. In the western medicine group, the western medicine comprehensive therapy was adopted. 10-day treatment made one session. Two sessions of treatment were required. In 1 or 2 sessions of treatment, the efficacy was observed, the electric audiometry was evaluated. Additionally, the blood routine and liver and kidney functions were detected. Results The total effective rate was 50.0% （16/32） in the acupuncture ＋ medication group and was 55.9% （19/34） in the western medicine group. The efficacies were similar between the two groups （P〉0.05）. In 1 and 2 sessions of treatment, at 250 Hz, 500 Hz and 1 kHz, the electric audiometry values in either group were recovered significantly as compared with those before treatment （all P〈0.01）. At 2 kHz, in 1 and 2 sessions of treatment, the improvements of the electric audiometry values were significant as compared with those before treatment in the acupuncture plus medication group separately （P〈0.05, P〈0.01）. At 4 kHz, the differences were not significant statistically before and after treatment in either group （all P〉0.05）. There were no abnormalities in the blood routine and liver and kidney function detections before and after treatment in either group. Conclusion Either the comprehensive therapy of electroacupuncture and western medicine or the simple western medicine comprehensive therapy is effective in the treatment of low frequency hearing damage of sudden deafness. Either of them has no effect on high frequency hearing damage. But for the middle frequency hearing damage, the efficacy of the comprehensive therapy of electroacupuncture and western medicine is superior to that of the simple western medicine comprehensive therapy.

Deafness genes for nonsyndromic hearing loss and current studies in China

Objectives To review the identified deafness genes related to nonsyndromic hearing loss (NSHL) and summarize their expressions and functions in the cochlea and to introduce the current studies of molecular genetics on NSHL in China Methods The presented data are based on a review of the literature as well as the author's experience with NSHL and communications with other researchers in China over the past 3 years Results Currently, 23 deafness genes related to NSHL have been cloned and identified Some genes are associated with both NSHL and syndromic hearing loss (SHL), in both dominant and recessive deafness Deafness genes have a highly specific expression pattern in the inner ear Some functional categories are starting to emerge from a characterization of deafness genes There are interacting genes in the genetic background that influence the extent of hearing impairment The GJB3 gene, which is associated with high frequency hearing impairment, was cloned in a Chinese laboratory Mutations in some genes, such as GJB2 and mitochondrial 12S rRNA, have been screened in Chinese patients with NSHL Mapping new deafness gene loci as well as identifying new genes and their functions is an active area of study in China Conclusions It is challenging for us to continue identifying new deafness genes and analyze gene functions By identifying genes responsible for monogenic hearing impairment, more insight may be gained into the molecular process of hearing and the pathology of hearing loss
